The Soviets have already made it clear that they intend to go there, and they have the technology to do so. Or perhaps they mean American? If they want an international effort, they should target their petition at ALL the Governments of the world capable of contributing to the human exploration of Mars. If they want an American effort, they should be more careful in the wording.

It burned up in the atmosphere, but: some chunks of it did not. Most noticable of these was the plutonium powered generator, now somewhere at the bottom of the Indian Ocean I believe. Not much has been said about this... The Galileo Jupiter probe will be similarly powered, current flightpath calls for a close Earth gravity assist fly-by.

A letter contract has been signed with Boeing Military Airplane Co., a division of the Boeing Company, Seattle, to reserve the aircraft for NASA use. The additional SCA will provide increased ferrying capability and eliminate a potential single-point failure in the space transportation system. The 231-foot long aircraft will be modified to carry Shuttle orbiter vehicles from landing sites to orbiter processing facilities at the Kennedy Space Center, Fla. Modifications will be made by Boeing at their manufacturing facilities in Wichita, Kan. The 747-100 is nearly identical to the original SCA and was selected to minimize costs associated with modifications and operations. The original SCA has transported orbiters since 1977 when orbiter Enterprise was first used for unpowered atmospheric flight tests. Since then, Columbia, Challenger, Discovery and Atlantis have been ferried coast to coast atop the SCA. Total cost of the aircraft and required modifications is currently under negotiations. That figure is expected to be available this summer. ----------------------------------------------------------------------- Reprinted with permission for electronic distribution NASA News Release 88-28 By Sarah Keegan Headquarters, Washington, D.C. and Jeffrey Carr Johnson Space Center, Houston ------------------------------ Date: 27 Mar 88 15:55:37 GMT From: cu-den!udenva!isis!scicom!embudo!markf@boulder.colorado.edu (markf) Subject: NASA News NASA NEWS NASA ISSUES UPDATED MIXED FLEET MANIFEST NASA ... issued an updated mixed fleet manifest reflecting current planning for primary payloads for Space Shuttle missions and expendable launch vehicles (ELVs) through Fiscal Year 1993. The manifest is for planning purposes only. Firm Shuttle payload assignmentsare made during the formal integration process at approximately 19 months prior to launch. The planned next Shuttle launch (STS-26) remains in August 1988. In addition to supporting Department of Defense mission requirements and the Commercial Space Initiative recently announced in conjunction with the new National Space Policy, this mixed fleet manifest continues to reflect the high priority assigned to civil space science and applications payloads, both on the Shuttle and ELVs. A decision to interchange the STS-29 and STS-28 missions eases the orbiter processing flow and enables NASA to maintain the required launch windows for two interplanetary missions in 1989 -- Magellan, a mission to map the planet Venus in April, Galileo, a cooperative project with Germany to survey Jupiter and its moons,in October. The Hubble Space Telescope also maintains its flight assignment date of June 1989. Astro-1, a Spacelab mission designed to study the univers in the ultraviolet spectrum is being reconfigured to enhance the study of Supernova 1987A, an event that has drawn the attention of astrophysicists from around the world. The Broad-Band X-Ray Telescope has been added to complement the Astro-1 mission now slated to fly on STS-35 in November 1989. Taking advantage of the recently announced Shuttle downweight additional capability, Spacelab missions are now planned to fly aboard the orbiter Columbia (OV-102), which was not previously possible. Two Spacelab payloads have been assigned flights in 1990 -- a Spacelab Life Science mission in March and the first of the Atomospheric Laboratory for Applications and Science mission series, Atlas-1, scheduled for projected schedule, is now slated for March 1990 and the Ulysses projected October 1990 launch date. Another important addition to the manifest is a misson to retrieve the Long Duration Exposure Facility (LDEF) in July 1989. Launched by the Space Shuttle in April 1984, LDEF originally was scheduled for retrieval in March 1985. The LDEF retrieval mission will replace Astro-1 as the payload for STS-32. The manifest supports the commercial space initiative announced with the National Space Policy, February 11, 1988, as follows: - The Industrial Space Facility (ISF) is manifested as a fully reimbursable payload under a pre-existing agreement. - The Spacehab is manifested as a fully reimbursable payload. - The Commercially Developed Space Facility (CDSF) will be manifested when the government's lease arrangements are complete. All of the above are subject to further negotiations with the appropriate commercial organizations and specific manifesting decisions will depend on commercial customer demand. This mixed fleet manifest continues to reflect NASA's plans to use ELVs for those payloads that do not need the capabilities of the Space Shuttle. Thirty-five ELV launches are planned through FY 1993. ------------------------------------------------------------------- Republished with permission for electronic distribution Nasa News Release 88-38 March 15, 1988 By Barbara E.

Actually, you have to play the odds when selecting a size for the structural members. If you build the members large enough so they cant be destroyed by meteoroids would be prohibitively expensive. Dust pitting the mirror may be more of a problem than meteoroids actually penetrating it. Michael. -- Internet: montague@sun.soe.clarkson.edu | Woody's my hero...

This will be a long range (15-25 years) set of goals and objectives for the lab. Most of the other NASA field centers have published such statements recently. It was reported that as a result of writing its statement, Lewis has already decided to divest itself of its communication effort. ------------------------------ Date: Thu, 31 Mar 88 10:33:14 PST From: tencati@vlsi.jpl.nasa.gov (Ron Tencati) Subject: Some Articles of Interest X-St-Vmsmail-To: ST%"space@angband.s1.gov" The following is a small compenduim of news articles relating to recent events of interest Ron Tencati Jet Propulsion Laboratory ---------------------------------------------------------------------------- WASHINGTON POST, MARCH 18 "SOVIETS TO FLY U.S. PLAQUE TO MARS MOON" "Soviet officials have agreed to place aboard their spacecraft bond for the Martian moon Phobos a plaque commemorating the moon's discovery by an American." The POST says in an informal ceremony in Houston, NASA science official Bevan French presented the plaque to scientist Lev Mukhin of the Soviet Space Research Institute. The Soviets have scheduled a July launch, scheduled to reach the Martian moon in the spring of 1989. "I can promise the plaque will be installed on the lander," the robot vehicle that will descend to the moon's surface, Mukhin said afterward. "This means it will remain on Phobos forever." The POST says the two moons of Mars, Phobos and Deimos, were discovered in 1877 by astronomer Asaph Hall of the U.S. Naval Observatory in Washington, D.C. ********************* WASHINGTON POST, MARCH 18 "SOVIET SATELLITE LAUNCH" "The Soviet Union entered the commercial space race with its first paid-for-launch of a foreign satellite, a 1-ton weather monitor for the Indian government that was placed into a near- Earth polar orbit on a Vostok rocket from the Baikonur Cosmodrome in Kazahstan." The POST says the head of the Soviet space engineering agency, Alexander Dunayev, said his government was losing money on the deal. No price was mentioned in the story. ******************* NEW YORK TIMES, MARCH 18 "U.S. REVISES SPACE MISSIONS" "The space agency has revised its schedule of space shuttle flights and cargoes, adding a mission that is to retrieve a bus- size satellite left in space in 1984 for what was to have been one year." The TIMES story says the satellite has led scientists to conclude that it could crash through the atmosphere and burn up if it is not retrieved. The story says the Shuttle schedule reverses the order of one military and once civilian flight early next year. It says this enables NASA to orbit a pair of communications satellites earlier than planned--because they will be needed in June 1989 when the Hubble Space Telescope is launched from a Shuttle. ******************** AEROSPACE DAILY, MARCH 18 "SUCCESS OF MANNED MISSION GOALS LINKED TO CORE TECHNOLOGIES" "Developing life support systems, determining criteria for crew selection and finding ways to deal with the rigours of long term space flight are some of the supporting research technologies which must be addressed further if NASA is to meet its long term space exploration goals, Ames Research Center officials reported." "We don't know how to do a lot of those things" necessary for long duration manned missions, said Bruce Webbon, chief of the Crew Research and Space Human Factors branch at Ames. "We haven't done the homework and the foundation isn't there." Webbon told the DAILY that project Pathfinder, which NASA requested $100 million in FY '89, will provide the missing link needed to develop the technology base which will make long term missions a reality. ********************* NEWSWEEK Magazine, MARCH 21 "THE SPACE RACE HEATS UP AGAIN" By: Frank Givney and John Schwartz "The ancient Romans had a saying: 'To the stars through difficulties.' America's private space industry might adopt it as a motto." The article says last month the Reagan administration issued a directive urging NASA to work more closely with the private sector, a boost that could be worth millions. It outlines the plans of Space Industries Inc., and its Industrial Space Facility; Space Services, run by former astronaut Donald "Deke" Slayton, and American Rocket Co. * * * * NEWSWEEK, MARCH 21 "IS THE NEW SHUTTLE ROCKET FIT FOR TAKEOFF?" By: Harry Hurt "More than two years after the Challenger disaster, the last shipment of main booster parts for the new space shuttle Discovery arrived at the Kennedy Space Center in Florida last week. Morton Thiokol, the Utah-based company that built the flawed Challenger booster, has made key changes in the solid rocket motors. But as technicians stack the parts for a planned Aug. 4 launch, a battle is still raging over whether the new booster is safe." The article goes on to discuss the various re-designed parts of the booster, and lists pro and con arguements about its ability to do the job safely. ******************** PHILADELPHIA INQUIRER, MARCH 17 "SCIENTISTS: STUDY SUPPORTS THEORY THAT METEORITE DOOMED DINOSAURS" By: Thomas Maugh "Two scientists who experimented with a 50-foot 'gun' to simulate the impact of a giant meteorite on prehistoric earth have concluded that such a collision could have raised temperatures enough to have killed off the dinosaurs." The story says research by the California Institute of Technology suggests that if a meteorite or comet 10 miles in diameter struck 65 million years ago, it would have released two to five times as much carbon dioxide as was already in the atmosphere. The carbon dioxide would have produced a "greenhouse effect." The story says this would have killed off many of the dinosaurs as well as the leafy plants they fed on. ------------------------------ End of SPACE Digest V8 #186 *******************
