Glenn Shuttle Mission a Success
The space shuttle Discovery landed at Florida's Kennedy Space
Center Saturday afternoon, November 7, wrapping up one of the most
publicized shuttle missions in history.
The shuttle landed at 12:04 pm EST (1704 UT) at Kennedy Space
Center's Runway 15. The shuttle had no problems with the landing,
even though the drag chute was not used to help slow the shuttle down.
Engineers had been concerned about the drag chute after the
drag chute door fell off seconds before launch October 29. There was
a remote possibility that the chute would deploy before landing, which
would have resulted in a harder-than-normal landing that might have
blown out a tire or damaged a strut.
Mission controllers were concerned with the weather in the
hours leading up to the landing, but skies remained clear and winds
were low enough to permit a landing on the first possible time. A
second landing time an hour and a half later was also available, as
were two landing times at Edwards Air Force Base in California.
Senator and former astronaut John Glenn reported no problems
with his return to Earth. Modifying a line he said in orbit last week
and during his first space mission in 1962, he commented just after
landing over the radio, "One-g and I feel fine."
"I'm about 95 to 98 percent back to normal," Glenn told
reporters at a post-flight press conference November 8. He
acknowledged that he couldn't move his head around quickly without
feeling uncomfortable, a condition common to astronauts after their
return to Earth.
Glenn said the mission went "very well", and he worked with
the rest of the crew without problems. "This is really an outstanding
crew," he said.
While Glenn said he has a "very definite obligation" to
complete the scientific followup to the mission, he said he had no
definite plans for any public relations followup, although he is open
to any plans NASA has. "I firmly believe this is a good program," he
said. "If I can help relay that feeling to more people, then I would
like to do that."
Mission STS-95, publicized for its flight of Glenn, is
regarded as a great success by NASA. The crew successfully deployed
and retrieved the Spartan-201 solar science satellite, deployed a
small Navy comsat, and conducted a number of experiments.
A week after the end of the mission, the publicity that
followed the mission had faded considerably. Glenn and the STS-95
crew were treated to a Veterans Day parade in Houston November 11, and
a ticker-tape parade is planned for New York this week. However, his
first post-flight interview, on the NBC TV program "Meet the Press"
November 15, was interrupted part way through by coverage of the Iraq
crisis.
The next shuttle flight is STS-88, the first International
Space Station assembly flight. Launch of the shuttle Endeavour is
scheduled for December 3.
ISS Orbit Change Dropped
Russia has withdrawn a request to alter the orbit of the
International Space Station so that it would lie in the same plane as
the existing Mir space station, the Russian Space Agency announced
Wednesday, November 11.
Russia had requested permission from NASA last week to launch
the Zarya control module, the first element of ISS, ten hours later
than planned. This would have put the module in the same orbit as
Mir, making the transfer of equipment or even entire modules from Mir
to ISS relatively easy.
Instead, a Russian Space Agency spokesman told Reuters, "The
launch will take place on November 20 at 9:40 am (1:40 am EST, 0640
UT) as planned."
Analysts in the U.S. were concerned that the request, made two
weeks before the launch, was a move to help them keep operating Mir.
The station is scheduled to be deorbited in mid-1999, but some
Russians have openly advocated keeping the station operational past
that date.
Some experts have also suggested that Russia would like to
take one or more existing modules from Mir and use them on ISS in
place of building new research modules, as originally planned. The
current poor state of the Russian economy may prevent their
construction, and has already delayed the launch of the Service Module
by over a year.
Another key Russian spoke out Wednesday in favor of keeping
Mir in orbit. "It is purely a political question that there is
pressure for us to get rid of Mir as soon as possible," veteran
cosmonaut Anatoly Solovyov told Reuters. "It is clear why. Who has the
station? We do."
Solovyov said Mir should be kept operational for at least two,
and as many as five, years. A spokesman for Energia RSC, the Russian
company that operates Mir for the Russian Space Agency, claimed that
up to 100,000 people could lose their jobs if Mir was deorbited next
year as planned.
Had Zarya's launch been adjusted to place it in a different
orbit, the launch of STS-88, the first shuttle mission dedicated to
ISS assembly, may have been delayed even longer. The online
publication NASA Watch reported Tuesday that the shuttle launch could
have been pushed back from December 3 to the 17th or 18th, because the
Sun's angle to the orbital plane would be high enough to violate solar
exposure limits.

Observers, Spacecraft Gear Up for Leonid Storm
Astronomers around the world are preparing to observe what may
be a heavy "storm" of meteors from the Leonids this week, while others
take measures to protect spacecraft from the hail of tiny rocks that
threaten to damage or disable them.
The Leonids are one of several meteor showers that take place
annually. The Leonids, associated with the comet Tempel-Tuttle, peaks
every November 17-18. However, about every 33 years the Leonids are
significantly stronger as the Earth passes through a region near the
comet itself. The last such peak was in 1966, so 1998 and/or 1999 are
thought likely to have similar meteor "storms".
The peak of the storm, when thousands of meteors are observed
over the course of a single hour, is forecast to be observable from
the Far East and central Asia. NASA has dispatched two aircraft that
will observe the storm while flying above Japan.
"The central theme of this mission is astrobiology," said
principal investigator Peter Jenniskens of the SETI Institute. The
instruments on the aircraft will look for traces of organic molecules
in the meteor trails. "This may help us understand how
extraterrestrial materials helped create the conditions on Earth
necessary for the origin of life."
Other observing plans are in the works worldwide, with efforts
concentrating on China, Mongolia, Thailand, and other regions expected
to be able to see the peak of the storm.
While astronomers prepare to feast on the burst of meteors
that will be visible, spacecraft operators are taking measures to
protect their satellites against any possible damage from the meteors.
While the meteors will be small, there will be many of them
during the peak of storm, all traveling at speeds up to 72 kilometers
per second (45 miles per second), making the Leonids 13-18 times more
energetic than a typical meteor. However, the Leonids are believed to
be smaller than typical meteors, lessening their effects.
Engineers are less concerned with damage from the Leonids
themselves but secondary effects from meteor impacts. "The meteoroids
are probably not going to punch a hole through a satellite," noted Jim
Woodburn, chief orbital scientist for Analytical Graphics, Inc.,
makers of Satellite Tool Kit software. "But when they hit something,
they are going so fast that the object will vaporize into plasma,
which has a real potential to wipe out the sensitive electronic
equipment on-board satellites."
In 1993 the European Space Agency's Olympus communications
spacecraft was lost after the Perseid meteor shower. Engineers
believe that a meteor hit the spacecraft, creating a plasma cloud that
shorted out the electronics on the spacecraft.
Controllers will move many satellites into orientations to
minimize the amount of the spacecraft exposed to the meteor stream,
although in most cases spacecraft operations will continue. In some
cases, like the Rossi X-Ray Timing Explorer, instrument will be turned
off to prevent them shorting out form an impact.
The Hubble Space Telescope will be rotated so that its mirrors
will be pointed away from the meteors, and its solar panels similarly
aligned. However, HST observations will continue, as the spacecraft
takes a 10-hour observation a quasar, along with Kuiper Belt Object
searches and engineering studies to investigate the properties of
meteor dust.
The Mir crew will continue work during the Leonids, but may be
ordered to the relative security of the Soyuz escape module during the
peak of the storm. A spacewalk last week by the Mir crew installed an
experiment to collect Leonid and other meteorite samples.
The storms, which may also be visible in the Leonid showers of
1999 and 2000, are expected to be the last for some time. The 33-year
cycle of storms will be interrupted in 2029 when a close pass to
Jupiter by comet Tempel-Tuttle will alter its orbit away from the
Earth, meaning the storms may not return for 100 years.
[Ed. Note: Check out our special feature on the Leonids at
http://www.spaceviews.com/features/leonids/ for more information about
this meteor storm and links to other resources on the Web. We'll be
adding more information over the next several days.]
DS1 Ion Engine Shuts Down
The ion engine on the experimental Deep Space 1 (DS1)
spacecraft shut down just a few minutes after it was used for the
first time Tuesday, November 10.
Mission controllers were able to recover the spacecraft from a
"safe mode" Friday, November 13, two days after a problem with a star
tracker stopped normal operations.
The engine, one of the showcase pieces of new technology on
the spacecraft, shut down 4 1/2 minutes after it was started around
2:30 pm EST (1930 UT) November 10. The cause of the shut down is not
known, and efforts to restart the engine Tuesday failed.
The engine test was the first time the ion engine had been
used to propel the spacecraft. The engine had been powered up and
checked out prior to Tuesday's test, without any problems.
JPL, the center running the DS1 mission, noted that ion engine
"turn-off" has been seen in ground tests and in Earth-orbit spacecraft
before. "Deep Space 1 is designed to test and validate the use of
such propulsion in deep space for the first time, so the ongoing
diagnosis of Tuesday's behavior is in keeping with the mission's
goals," mission officials reported in a statement.
The spacecraft collected "valuable diagnostic data" during the
engine problems, JPL reported, and also noted that all the other
systems on DS1 appeared to be functioning normally.
On Wednesday, November 11, DS1 entered a "safe mode" when
software on the spacecraft detected a problem with a star tracker.
The tracker, used to determine the orientation and location of the
spacecraft, lost its lock on a star. Efforts by the onboard
fault-protection software to correct the problem failed, so it placed
the spacecraft into a safe mode to await commands from Earth.
Engineers on the ground were able to get the star tracker
working again, but are unsure if it is a problem with the tracker
itself or software used to communication between the tracker and the
spacecraft's other systems. Controllers were able to put the
spacecraft back into normal cruise operations on Friday, November 13.
JPL reported that engineers will not work with the ion engine
until late next week, more than a week after the problem first
appeared. In the meantime other spacecraft systems, including
instruments and control systems, will be checked out.
DS1 is the first mission of the New Millennium Program, a NASA
effort to develop and flight-test new technologies that can be used in
future missions. The ion engine in DS1 is one of the key technologies
being tested on the mission, as well as advanced solar panels,
autonomous control systems, and scientific instruments.
DS1's prime mission is to test the new technologies, however,
there are science plans for the mission as well. The spacecraft,
launched October 24, is scheduled to fly by the asteroid 1992 KD in
July 1999, and may fly by two comets in 2001 if the mission is
extended. To meet those goals, though, the ion engine must work, as
the spacecraft has no other propulsion system.

Engine Problems Delay X-33 First Flight
The first flight of the X-33, a vehicle designed to test
technologies for use in future reusable launch vehicles, will be
delayed at least six months to the end of 1999 because of problems
with its engine, according to press reports.
The trade weekly Space News reported this week that problems
manufacturing the aerospike engine for the X-33 will push back the
launch to at least December 1999, six months later than planned, and
add $36 million to the cost of the program.
The problem is specifically related to difficulties bonding
key high-temperature portions of the XRS-2200 engine together,
according to a report in the Los Angeles Times. Rocketdyne, the
Boeing subsidiary building the engine as a subcontractor to Lockheed
Martin, has had problems with the V-shaped nozzle ramp of the engine.
Unlike conventional engines, an aerospike engine does not have
a bell-shaped nozzle for the exhaust to push against. Instead, a
nozzle ramp is used, which allows for the optimal expansion of the
exhaust plume, making the engine more efficient. Conventional nozzles
don't permit such expansion, reducing the efficiency of those engines,
particularly at high altitudes.
The delay will cost the project an additional $36 million, but
Rocketdyne will be expected to pick up the additional tab, according
to Jerry Rising, a Lockheed Martin vice president supervising the X-33
project. "We are not going to add any more [funding] to the program,
so we're expecting Rocketdyne to make up that difference," he told the
Times.
Other parts of the X-33 project are expected to continue as
planned, Rising said. Lockheed Martin will ship the completed X-33,
minus engine, to the test range at Edwards Air Force Base, California,
for tests. Lockheed Martin has also suspended overtime work on the
project.
However, one anonymous worker told the Times that the delay
will give other parts of the project a chance to catch up. "I think
most of us are happy that Rocketdyne said they were going to be late,"
said the unidentified employee, working for one of the subcontractors.
"I think everybody is running behind."
Lockheed Martin was awarded a NASA contract in July 1996 to
build the X-33. NASA planned to spend $941 million in a fixed-cost
contract, and Lockheed Martin planned to invest at least $220 million
into the project. The first launch was originally planned for March
1999, with fifteen test flights to be completed by December 1999. The
launch date was pushed back to July 1999 last year.
The X-33 is not designed to go into orbit. It will conduct a
series of atmospheric flights across the western U.S. to test the
engine, structures, and other features of the vehicle.
X-33 is a one-half scale model of VentureStar, a proposed
single-stage to orbit reusable launch vehicle. Lockheed Martin will
make a decision to build the VentureStar pending the results of the
X-33 flights. The VentureStar would cost an estimated $5 billion to
develop, and would be a privately, not NASA, funded project.
Mir Cosmonauts Complete Spacewalk
Two cosmonauts on the Russian space station Mir completed a
six-hour spacewalk late Tuesday, November 10, installing a meteorite
experiment to the hull of the space station, while officials on the
ground discussed extending the life of the aging station.
Cosmonauts Gennady Padalka and Sergei Avdeyev spent six hours
outside Mir November 10, starting at 2:24 pm EST (1924 UT). The two
installed a "meteorite trap", a French experiment to collect data on
meteorites, including pieces of the meteors themselves. The
experiment will stay on the station until early 1999, when it is
removed and sent back to Earth.
The spacewalk was timed so that the experiment would be in
place before the Leonid meteor shower next week. Astronomers expect
the shower to be especially intense this year and/or next year, part
of a 33-year cycle of Leonid meteor "storms".
The storm should not be a hazard to Mir, Russian officials
said, but they will order the crew to take shelter in the Soyuz
spacecraft docked to Mir during the heaviest part of the storm.
Padalka and Avdeyev also deployed a small student-built
satellite, Sputnik-41, and several other experiments during the
spacewalk, which ended at 8:18 pm EST (0118 UT November 11).
The spacewalk came as Russian Space Agency officials suggested
that Mir may not be deorbited as planned in mid-1999 but be kept in
orbit while assembly of the International Space Station begins. Last
week Russia requested to NASA that the launch of the first element of
the ISS, the Zarya control module, be pushed back 10 hours so its
orbit will be in the same plane as Mir, making the transfer of
equipment from one station to the other easier.
Same analysts in the U.S. suggest that the move is being
requested not as just a way to move equipment, but to transfer whole
modules from Mir to ISS, should Russia not be able to build its
planned research modules for the new station. This would require
keeping Mir in orbit past mid-1999 until ISS could accommodate the Mir
modules.
"There is nothing crafty in this," Boris Bodin, the RSA's head
of long-term planning, told Reuters. "Our thinking is based on
assuring the long-term presence of man in space."
NASA expects to make a decision this week on the Russia
request to change the orbit plane of the ISS, a move which could delay
the launch of STS-88, the first shuttle mission devoted to ISS
assembly. Zarya is slated for a November 20 launch and STS-88,
carrying the Unity docking module, for December 3.
Proton, Delta Boosters Launch Satellites
A Russian Proton rocket launched an American communications
satellite early Wednesday, November 4, while a Boeing Delta 2 lifted
off early Friday, November 6, carrying five satellites that will back
up the Iridium global phone service system.
The Proton launched the PanAmSat PAS-8 satellite at 12:12 am
EST (0512 UT, 10:12 am local time) from Baikonur, Kazakhstan. The
Proton and its Blok DM upper stage successfully placed PAS-8 into
orbit.
The satellite, build by Space Systems/Loral, will provide
video, telecommunications, and Internet-related services for the
Asia-Pacific region. PanAmSat plans to use the satellite to help
provide coverage of the 2000 Summer Olympics in Sydney, Australia.
The Delta 2 lifted off at 8:37 am EST (1337 UT) from
Vandenberg Air Force Base, California. The five Iridium satellites on
board the booster were successfully deployed about 85 minutes after
launch.
Four of the five satellites launch wills serve as on-orbit
spares, should any of the 66 active satellite fail. The fifth will
fill an operational slot in the satellite constellation.
The launch comes the same week as Iridium entered commercial
service, after a delay of just over a month. The company provides
worldwide cellular phone service, relaying calls from mobile phones
via the satellite constellation.

*** Policy ***
Consultants Issue Recommendations on NASA Space Flight Options
NASA should continue using the space shuttle until private
industry, in cooperation with but not funded by the space agency,
develops a human-rated reusable launch vehicle (RLV) that can meet
NASA's needs at reduced costs, a consultant report issued last week
concluded.
The report, commissioned by NASA and carried out by
Boston-based Hawthorne, Krauss, & Associates (HKA), explored several
options for future NASA space access, ranging from continued use of
the shuttle to using alternative RLVs. They concluded that a approach
combining several options, and not very different from
previously-stated NASA plans, was the best way to proceed.
"The key to NASA's success in significantly reducing launch
costs over the long-term is the active involvement of the private
sector in a substantive risk-sharing role," HKA noted in its report.
The firm noted that NASA should continue operating the space
shuttle in the near term, until a replacement vehicle is available.
That replacement RLV should be privately developed, with NASA as one
customer among many, although NASA should "enable the development" of
such a vehicle to make sure it is consistent with NASA's needs.
The consultants ruled out other options such as shuttle
upgrades, noting that options like liquid flyback boosters would costs
several billion dollars and keep NASA in the operations business.
Purchasing other RLV services, such as those planned by companies like
Kistler, Kelly, and Rotary Rocket, would also not be beneficial, since
they would not necessarily meet NASA's needs for human access.
However, HKA left open the option of transferring one or more
shuttles to private industry. Such a move could "generate valuable
commercial momentum" for NASA and create market awareness for future
commercial space projects.
Any effort by NASA to work with commercial RLV makers should
put as much of the risk of the project as possible on the companies
and not on NASA. "Significant private-sector risk sharing will best
assure that the new RLV project delivers on its projected costs and
capabilities," the consultants said.
Because of that, the report cautioned against the use of
government loan guarantees, one widely-cited way to support commercial
RLV development. "Loan guarantees... have the potential to place the
government in the position of accepting all (or most of) the risk,
with the private sector keeping all (or most of) the reward," HKA
reported. "This would be a bad outcome."
NASA plans to use the HKA report along with its Space
Transportation Architecture Study, currently in progress, to develop a
plan for future human space access by the space agency. One-year
contracts for the architecture studies were handed out in September.
ESA Gives Go Ahead for Mars Express
The European Space Agency (ESA) announced November 5 that has
approved plans for Mars Express, a combination orbiter and lander to
be sent to Mars in 2003.
All 14 member nations of ESA's Science Program Committee
approved the mission concept, contingent on funding being available
for the mission. The mission is projected to cost 150 million Euros
(US$175 million).
"The green light for Mars Express shows that Europe is
perfectly capable of seizing special chances in exploring space," said
Roger Bonnet, ESA's director of science. He noted that Mars Express
would be the least expensive and one of the most original Mars
missions planned.
Mars Express is scheduled for launch on a Russian Soyuz rocket
in June 2003. The spacecraft will carry seven scientific instruments,
including some related to European instruments lost on the Russian
Mars 96 spacecraft when it crashed to Earth shortly after its November
1996 launch.
The instruments will include a high-resolution camera and a
ground-penetrating radar. The latter instrument will give scientists
their first opportunity to search for groundwater or ice hidden
beneath the Martian surface.
The mission will also carry a lander. The Beagle 2 is being
designed by Open University in the UK with contributions from other
countries. The 60-kg (132-lb.) lander will carry a camera and
instruments to study the Martian soil and rocks for evidence of past
life. The addition of Beagle 2 is dependent on the lander's
developers meeting their own financial commitments.
The Mars Express mission will play two roles for ESA,
according to Bonnet. "Mars Express has been advertised by the Science
Program Committee as a test case for new approaches in procuring and
managing future science projects, with a view to achieving major
savings," he said. "In the international arena, Mars Express will
confirm Europe's interest in a major target for space research in the
new century, when we make our forceful debut at the Red Planet."

Australian Senate Introduces Space Bill
A bill designed to set the regulatory framework for commercial
space launches by expendable and reusable launch vehicles was
introduced into the Australian Senate on Thursday, November 12.
The Space Activities Bill of 1998 would create regulations for
securing licenses for commercial launches from Australian sites, as
well as licenses for the return of reusable launchers. It also sets
insurance requirements for any Australian launches.
The bill is similar to the Commercial Space Act of 1998,
passed by the U.S. Congress and signed into law last month. However,
while the American bill expanded an existing regulatory scheme to
promote further commercial space endeavors, the Australian bill aims
to create a new regulatory environment from scratch.
"Since the mid 1980s a range of commercial space launch
projects have been proposed for Australia," noted Sen. Rod Kemp, who
introduced the bill. "A clear legislative and regulatory framework is
essential for any of these projects to proceed."
Most recently, American company Kistler Aerospace decided
earlier this year to develop a spaceport in Woomera for its K-1
reusable launch vehicle. The company chose to go to Australia because
U.S. regulations at the time didn't permit the licensing of a reusable
launch vehicle.
Although there were no commercial launch regulations in
Australia at the time Kistler decision, the company reached an
agreement with the government. That agreement will remain in force
regardless of whether the Space Activities Bill is passed, Kemp said.
Kemp did not outline what the terms of the government's
agreement with Kistler was, but noted that the bill would "achieve a
regulatory regime largely consistent with that applied to Kistler."
Other aspects of the bill, including accident investigation and
penalty provisions, will affect Kistler if the bill is enacted.
The legislative framework in the bill would be implemented by
a new office, the Space Licensing and Safety Office (SLASO). The
current Australian budget includes A$1.3 million (US$830,000) to
establish the office.
The bill is Australia's latest effort to attract commercial
space companies. Earlier this year the Australian federal government
approved a waiver of the 22% national sales tax on launch vehicles and
satellites.
The bill passed through the initial formalities of a first and
second reading when introduced November 12. Further consideration of
the bill will take place later in the month.

NASA Selects Discovery Mission Candidates
NASA announced the selection of five finalists for the next
round of the Discovery Program of low-cost space science missions,
including two missions seeking a second chance at funding, Thursday,
November 12.
The five missions, ranging in focus from Mercury to Jupiter,
will receive funding to conduct four-month detailed studies before one
or two missions are selected for full funding in mid-1999.
"Deciding which one or two of these exciting finalists will be
fully developed will be a very difficult choice," said Ed Weiler,
acting associate administrator for space science at NASA. "Any one of
them promises to return unique insights into our solar system."
Two of the missions selected were also finalists in the last
round of Discovery Program selections in 1997. The Aladdin mission
would fire projectiles into the Martian moons Phobos and Deimos, then
fly through the debris created by the impacts to collect samples and
return them to Earth. The Mercury Surface, Space Environment,
Geochemistry and Ranging mission, or Messenger, mission would orbit
Mercury and provide the first global high-resolution images of the
innermost planet.
Among the other projects selected is "Deep Impact", which
would fire a 500-kg (1,100-lb.) projectile into the comet P/Tempel-1,
excavating fresh ice beneath the surface for study by the spacecraft.
The Interior Structure and Internal Dynamical Evolution of Jupiter
("INSIDE Jupiter") would orbit Jupiter and study its magnetic and
gravitational fields to learn more about the interior of the planet.
The Venus Sounder for Planetary Exploration, "Vesper", would orbit
Venus to study the composition and dynamics of the planet's middle
atmosphere.
NASA also announced that the Discovery Program would fund a
"Mission of Opportunity", a chance to fly an instrument on another
spacecraft. $5.3 million will go fund part of an instrument on
Europe's Mars Express spacecraft to study the interaction of the solar
wind with the Martian atmosphere.
Discovery missions are intended to be low-cost,
rapid-development missions to study specific planetary and space
science topics. NASA will select one or two of the finalists for full
funding in June 1999. Those missions will be required to launch by
September 2004 with a total development cost of no more than $190
million and total mission cost of $299 million.
Six Discovery missions have previously been selected. Of
those, three of them, the Near Earth Asteroid Rendezvous (NEAR)
mission, Mars Pathfinder, and Lunar Prospector, have already flown.
The fourth mission, Stardust, is scheduled for launch in February
1999. Stardust will fly through a tail of a comet to collect dust
samples and return them to Earth.
Genesis, a mission to study the solar wind, is scheduled for
launch in 2001. Contour, a mission to study the nuclei of three
comets, will launch in 2002.
X-Ray Observatory Mission Ends
A long-lived German X-ray astronomy satellite was shut down
Tuesday, November 3, after officials decided the damage to an
instrument from a recent mishap was irreversible.
A high-resolution camera on the Rontgensatellit (ROSAT) X-ray
observatory was damaged in September when it pointed too close to the
Sun. Engineers studying the instrument from then ground decided that
the instrument had been damaged beyond repair.
ROSAT, launched in 1990, had been suffering from a number of
problems in recent months. A failure in April of a navigational star
tracker, used to maintain the proper orientation of the satellite,
meant that the star tracker from another instrument had to be used in
its place.
That task proved to be more difficult than first thought, and
the spacecraft collected little data over the summer. Those problems
had largely been corrected with new software by September when the
accident with the High Resolution Imager (HRI) occurred.
HRI has been the only main focal plane instrument available
for use for the last four years on ROSAT, so its failure meant that
there was little use to continue to operate the satellite.
ROSAT started as a German project in 1975, and later grew to
include contributions from the United States and United Kingdom.
ROSAT was intended for launch on the space shuttle in 1987, but the
1986 Challenger accident delayed the mission. ROSAT was instead
launched on a Delta 2 booster in June, 1990.
For the first six months of its mission ROSAT made the first
all-sky survey of the sky at X-ray wavelengths, uncovering more than
60,000 X-ray sources, nearly 100 times more than any previous survey.
Since then ROSAT had been used for the specific study of X-ray
sources, from comets to quasars and neutron stars.
German officials said that large archive of data collected by
ROSAT will continue to be available for astronomers to use. Papers
using ROSAT data are being published in scientific journals at a rate
of more than one a day.

Astronomers Measure Rotation of Kuiper Belt Object
Astronomers have, for the first time, measured the rotation
period of a Kuiper Belt Object (KBO), one of thousands of large icy
bodies in the outer solar system, a team of European astronomers
reported last week.
The astronomers, from the European Southern Observatory in
Chile and the Observatoire de Paris, found that KBO 1996 TO66 rotates
once on its axis every six hours, a rate similar to comets and other
large icy bodies. They reported their findings at a special
conference in Germany.
The researchers used data from six nights of observations of
the KBO collected last year at ESO's New Technology Telescope in
Chile. They measured changes in brightness as 1996 TO66 rotated, and
found a repeating pattern ever six hours and 15 minutes, which they
inferred as the rotation period.
Using the brightness of the KBO and its distance -- some 45
Astronomical Units (6.8 billion km, 4.2 billion mi.) from the Sun --
they estimated that the object is about 600 km (370 mi.) in diameter.
That would make it among the largest KBOs known.
The rotation period, the first measured for a KBO, has
important implications. A large body like 1996 TO66 that has spent
its entire life in the outer solar system likely has not experienced
any forces strong enough to alter its rotation period, so may be
indicative of conditions during the formation of the solar system 4.5
billion years ago.
The rotation period is also similar to that of Chiron, a large
comet that orbits the Sun between Saturn and Uranus. It is much
shorter than the rotation period for Pluto and its moon Charon, who
each have rotation periods of nearly 6.4 days. However, while these
objects are thought to be the largest KBOs, they are locked in a
synchronous orbit around each other, and thus have had their rotation
rates changed since their formation.
1996 TO66 is one of more than 70 KBOs that have been
discovered since the first was found in 1992. These icy bodies are
thought to be left over from the formation of the solar system and may
serve as a source for comets. Up to 100,000 KBOs greater than 100 km
(60 mi.) in diameter are thought to exist.
While studies like these push current telescopes to their
limits, new larger telescopes and better instruments should permit
studies of KBOs, the astronomers say, and provide a better
understanding of the Kuiper Belt.
Astronomers Discover 1000th Pulsar
An international team of astronomers reported Friday, November
13, the discovery of 1000th pulsar known, an effort that highlights
the advanced technologies used -- and new difficulties faced -- in the
search for these unusual stars.
The discovery was made using a new search system at the Parkes
Radio Telescope in Australia, an effort that has discovered pulsars at
10 times the rate of any previous efforts.
Pulsars are rapidly-rotating neutron stars, dense remnants of
supernova explosions that weigh as much as the Sun but are only 20
kilometers (12 miles) in diameter. Neutron stars are so named because
their densities are so high that protons and electrons are thought to
combine to form neutrons.
Pulsars get their name from the rapid, regular radio pulses
that emanate from them. These pulses are formed by electrons flung
outward from the star in a beam formed by the star's powerful magnetic
field.
The first pulsar was discovered in 1967 and by last year 800
had been found. The new survey has discovered 200 in the last year,
and astronomers expect that 600 more will be found when the survey
ends in one year.
The increase in the discovery rate comes from a "multibeam"
receiver, whose 13 beams can scan different regions of the sky
simultaneously. "It's like having over a dozen giant radio telescopes
operating at once," explained Andrew Lyne of the University of
Manchester, England.
The new receiver required new data analysis systems to detect
the pulsars in the data, and also to deal with the increasing problem
of false detections from satellite signals, whose signals can mimic
pulsars. "Interference from human sources is a growing problem in
radio astronomy and we are having to strive ever harder to observe
through it," said team member Victoria Kaspi of MIT.
Astronomers hope the survey data will help them uncover
anything from a neutron star orbiting a black hole to gravitational
waves. The survey should also help astronomers find more rare
pulsars. "One of the main aims of the survey is to find more examples
of these rare types and perhaps other types not even known or
anticipated at present," said Dick Manchester of Australia's
Commonwealth Science and Industrial Research Organization.
The astronomers performing the pulsar survey include
researchers from the United Kingdom, United States, Australia, and
Italy.

Software Review: SkyBase
by Jeff Foust
If you've been following the development of the International
Space Station, odds are that you've grown a little impatient with its
interminable delays. And even with the first module scheduled for
launch from Kazakhstan in a few days, it will be years before it's
completed. If you'd like a look today at what the future will be
like, check out "SkyBase" from Piranha Interactive.
SkyBase is part educational tool, part simulator. The
software includes some basic information about the space station and
its systems, and details about each module of the ISS. There's also
information about the launch vehicle and launch sites that will be
used to put ISS in orbit.
The most interesting aspect, though, is the ability to
assemble your own space station, based on ISS components. You can put
the space station together, module by module, keeping any eye on power
and crew requirements. You can tour this station in 3-D from both the
inside and outside.
Playing with the space station assembly section is fun, but
this section could use more work. There are few goals for the
assembly section, and few penalties if you get something wrong. It
would be great if you had to design the station to meet some goals --
in terms of cost, number of launches, or scientific requirements --
but no such restrictions are place in SkyBase. The sheer number of
modules and other sections to choose from can be daunting, but you can
choose models from various stages of ISS construction, and work on
them from there.
SkyBase comes with only a very basic manual included in the
CD-ROM case, but the help section within the program fills that gap.
The program is very easy to install and run: I had no problems using
it on a relatively old and underpowered 133-MHz Pentium. If you're
looking for some fun space station simulations, SkyBase is a good
place to start.
SkyBase requires a 90 MHz or faster Pentium PC running Windows
95/98 and 16 MB of RAM. Also required are a 4x or faster CD-ROM,
sound card, and video display capable of 256 colors at 640x480
resolution. A modem can also be used to access the Internet from
within the program. The suggested retail price is US$29.95.

Airbreathing Engine Tests: Engineers have completed a series of tests
on a new air-breathing rocket engine that could dramatically lower the
cost of space access, NASA reported last week. Air-breathing engines,
like the one tested by the Marshall Space Flight Center, work
similarly to ordinary rocket engines but obtain their oxygen from the
atmosphere, much in the same way as a jet engine. Since a spacecraft
with such an engine would not have to carry its own oxidizer, it would
weigh far less and be much easier -- and presumably cheaper -- to get
into orbit. So far tested only in the lab, future flight versions are
in the works. "We've proven the technologies on the ground with
extensive testing of complex and technically challenging system
components," Uwe Hueter, manager of NASA's Advanced Reusable
Technologies research program, said. "Now, I believe we're ready to
demonstrate the technologies in flight."
Mars Pants: How do you prepare for the reduced gravity environment on
the surface of Mars? According to researchers at Oregon State
University, with a good pair of pants. Inflatable pants that raise the
center of gravity of a person can help astronauts adapt to lower
gravity conditions such as those found on Mars or the Moon, OSU
scientists found. The research could also have benefits for people
undergoing physical therapy. A prototype tested recently lowered the
effective weight of the wearer by 9 kg (20 lbs.) "When I try to walk
with the Mars pants on, I can actually feel myself rise up some off my
feet," said student Tyson Harty. "It changes my center of gravity and
affects the way I move."
Brits in Space: The British government is reportedly very interested
in flying an astronaut on the International Space Station, according
to reports late last week. The British paper The Daily Telegraph
reported Saturday, November 14, that British-born NASA astronaut
Michael Foale, best known for his tenure on the Mir space station last
year, helped bring together NASA and the government of Prime Minister
Tony Blair, who reportedly is keenly interested in getting Britain
involved in a project it so far has not contributed to. To fly an
astronaut on ISS, though, the UK will have to contribute something to
the station; engines to help keep the ISS in orbit may be one
contribution.
Space in the Movies: The surge in public interest in space from last
month's John Glenn launch may be the reason why space-related features
are getting picked up by networks and movie production companies. A
Dutch production company announced November 12 it plans to shoot a
feature on the life of Yuri Gagarin, the first man in space. The film
will be shot on location in Russia and Kazakhstan, including the
Baikonur launch site. Meanwhile, Fox has reached a deal with
filmmaker James Cameron, of "Titanic" and "Terminator" fame, to do a
miniseries based on the Red/Green/Blue Mars book trilogy by Kim
Stanley Robinson. The miniseries would be produced by early 2000, and
could later be turned into a series, Variety reported November 14.

Первый испанский космонавт будет работать и на Международной
космической станции
Испанский космонавт Педро Дюк (Pedro Duque), принимавший
участие в недавно закончившейся экспедиции Space Shuttle Discovery
STS-95, имеет хорошие перспективы работы на Международной
космической станции.
В этом полете принимал участие и самый старый астронавт -
77-летний Джон Гленн (John Glenn), который был первым американским
астронавтом, он первый раз летал в космос в 1962 г. А Педро Дюк
родился в марте 1963 г., он был самым молодым членом экипажа
экспедиции STS-95. Кроме того Дюк стал первым испанским
космонавтом. Теперь он, скорее всего, полетит в космос в качестве
астронавта Европейского космического агентства (ESA) на
Международной космической станции. Во время последнего полета,
который продолжался 9 дней, Дюк следил за работой научного
экспериментального оборудования ESA, эксперименты на котором были
подготовлены учеными из Бельгии, Великобритании, Франции,
Германии, Италии, Испании, Швеции и Швейцарии. Он принимал
большое участие и в медицинских экспериментах.

Ученые NASA будут ловить метеорные частицы потока Леониды с
помощью атмосферного зонда
[NASA] Hа российской станции "Мир" для поимки метеорных
частиц потока Леониды установлен специальный датчик-ловушка
российско-французского производства. А специалисты NASA запускают
для этой цели специальный атмосферный зонд, наполненный гелием. По
мнению руководителя этого проекта д-ра Дэвида Hоэвера (David Noever),
вероятность успеха невелика - менее 10%. Одной из целей эксперимента
также является поиск в пойманных метеорных частицах органических
соединений и других молекул, которые могут пролить свет на процессы
образования звезд и жизни на Земле. В пойманных частицах будут искать
аминокислоты и другие органические молекулы, необходимые для
возникновения жизни. Вряд ли жизнь могла возникнуть внутри комет, но
вещества которые они принесли на Землю миллиарды лет назад, в
земных условиях могли сыграть решающую роль в возникновении жизни.
Зонд планировалось запустить 17 ноября в 2 часа по Центральному
Стандартному Времени (11-00 по московскому времени). Подъем до
максимальной высоты 30 км должен длиться около 4 часов. Hа зонде
установлен аппарат для сбора метеорных частиц и ПЗС-видеокамера.
Ловить метеорные частицы планируется с помощью аэрогеля.
Аэрогель - это самое легкое из известных твердых веществ (его плотность
составляет 0,08 г/куб. см), оно считается самым лучшим средством для
захвата хрупких кометных частиц без повреждения последних. Летящая с
большой скоростью метеорная частица, застревая в аэрогеле оставляет в
нем конусообразный след длиной в 200 раз больше ее размера. Так как
аэрогель прозрачен, то видимые следы позволяют легко найти саму
частицу. Hа зонде установлены 24 аэрогельные ловушки диаметром 2,5 см
каждая.

NASA выбирает будущие космические проекты
[SpaceViews] В NASA объявлены 5 проектов-финалистов научной
программы Discovery. Из этих проектов в следующем раунде конкурса в
течение четырех месяцев детальных обсуждений будут отобраны один
или два, которые будут полностью профинансированы в июне 1999 г.
Диапазон целей этих проектов довольно широк - от Меркурия до
Юпитера. Два из них уже были финалистами в предыдущем отборе,
проводившемся в 1997 г. - проект Aladdin по отправке исследовательского
корабля к марсианским лунам Фобосу и Деймосу и возвращению его на
Землю и проект Mercury Surface по выводу космического корабля на
орбиту Меркурия и получения первых изображений высокого разрешения
этой планеты.
Третий проект - Deep Impact - предусматривает запуск 500-кг
космического корабля к комете P/Tempel-1 для исследования льда, из
которого состоит ее ядро. Следующий проект - INSIDE Jupiter -
предусматривает вывод спутника на орбиту Юпитера и исследование его
магнитных и гравитационных полей для уточнения внутренней
структуры планеты. В ходе реализации пятого проекта - Vesper -
космический корабль будет выведен на орбиту Венеры, откуда и будут
произведены исследования состава и динамики средних слоев атмосферы
этой планеты.
Кроме того NASA объявило о выделении 5,3 млн дол. для
разработки части оборудования европейского космического корабля Mars
Express, который проведет исследования взаимодействия солнечного
ветра с атмосферой Марса.
Один или два отобранных проекта будут реализованы к сентябрю
2004 г. Стоимость разработок не должна превысить 190 млн дол., а общая
стоимость проекта - 299 млн дол.

Открыт тысячный пульсар
Международная группа астрономов объявила об открытии
тысячного по счету пульсара. Это открытие было сделано с помощью
новой поисковой системы на радиотелескопе Parkes в Австралии.
Пульсары - это быстро вращающиеся нейтронные звезды, которые
появляются после взрыва сверхновой звезды, их масса сравнима с массой
Солнца, но их диаметр составляет всего лишь 20 км. Hейтронные звезды
получили такое название потому, что их плотность приблизительно
равно плотности протона и электрона, которые образуют нейтрон.
Пульсары получили свое название из-за испускаемых ими
радиоимпульсов, которые образуются при выбросе из недр звезды пучка
электронов, сформированного под действием мощного магнитного поля
звезды.
Первый пульсар был обнаружен в
1967 г. и к 1997 г. их было открыто 800
штук. В этом году астрономы открыли
200 пульсаров и в течение ближайшего
года предполагается открыть еще 600.
Такая высокая "скорость обнаружения"
пульсаров объясняется созданием
"многопучкового" приемника (на
снимке), который может сканировать
различные области звездного неба
своими 13 лучами.

Тема: Метеорный поток Леонид оказался не таким уж опасным
Привет всем!
Вот, свалилось из Internet...
Метеорный поток Леонид оказался не таким уж опасным
[SpaceViews] Hесмотря на мрачные прогнозы метеорный поток
Леонид пронесся не причинив большого вреда ни одному из
многочисленных спутников. Hе оправдались расчеты и интенсивности
метеорного дождя. Даже в оптимальных для наблюдения местах
количество "падающих звезд" оказалось намного меньше ожидаемого.
Два самолета NASA, летавших во время "пика" метеорного дождя
над Японским морем, записали в течение часа только 144 метеора, тогда
как по предварительным оценкам их число должно было доходить до
2000.
Однако наблюдатели в Европе и на Канарских островах были
вознаграждены за потраченное время, здесь пиковые значения превысили
несколько сотен метеоров в час.
Метеорный дождь не причинил вреда ни одному космическому
кораблю. Хозяева многих спутников приняли соответствующие меры
защиты, да и интенсивность метеорного потока оказалась невелика.
Во время прошлого пришествия потока Леонид зрелище было
гораздо более эффектным, тогда пиковое значение составило 144 тыс.
метеоров в час, или 40 штук в секунду.
Hа станции "Мир" также все закончилось благополучно. Станцию
заблаговременно повернули к потоку минимальным сечением, ее
дополнительно защищал грузовой корабль "Прогресс-М-40",
пристыкованный с этой стороны к модулю "Квант". Сами космонавты
Геннадий Падалка и Сергей Авдеев перешли на всякий случай в
спускаемый модуль "Союз ТМ-28", но, по их отзывам, мощного
метеорного потока они не наблюдали.
