Re the last remark about using large planets for assistance: gravitational assist only works if you want to accelerate the craft as well as re-point it. It always comes out of the encounter faster than it went in. If you want to get a craft in a distant orbit back to LEO, you'd have to slow it down by quite a bit when it got here. ------------------------------ Date: 7 May 90 17:15:11 GMT From: swrinde!cs.utexas.edu!uwm.edu!rpi!pawl13.pawl.rpi.edu!scholar@ucsd.edu (Scott E.

It docked with Mir early in the morning of May 8 and is said to have carried 2.5 Tonnes of food/fuel/supplies to the station. The Radio Moscow announcement stated that this is the last of the older Progress series, with the newer M being a reusable replacement (M series has flown 3 times, beginning in Aug. '89). It may be that this has been utilized because of the problems with the large Krystall expansion module which was to have flown to Mir early in April. That type of module typically brings about 7 tonnes of supplies (with a total module mass of 20 tonnes). Note that the older Progress M-3 had separated from Mir on Apr. 28th and was burned up in the atmosphere. (Radio Moscow May 5, 7, TASS announcements Apr. 29, May 6) Anatoly Solovyov and Alexander Balandin have now been in orbit for 87 days, exceeding the 84 day Skylab 4 mission (Nov. '73), the longest US flight. Indeed Solovyov, who also spent 9 days in zero G during the Soyuz TM-5/Mir mission in June '88, is now the 25th most experienced man in weightless flight. All these top 25 positions are now occupied by Soviet cosmonauts. It has been confirmed that the Soyuz TM-10 flight to Mir set for July will not carry a Soviet journalist to the station. Earlier Russian reporters had asked that the Soviet Journalist in Space mission be moved up to that date so that their countrymen could fly before the Japanese NHK reporter goes on the Soyuz TM-11 mission in Dec. However technical and training manners were too difficult to make this change according to a TASS announcement. Speculation is that the $12 million payment by the NHK television network for the Japanese visit is more important for their program than the prestige of having the first reporter in space being from the USSR. Of course many journalist in the west do not consider Soviet reporters all that highly so the gain by flying a Russian first would not be all that great.

Everywhere on the surface, it is of about 480 C +/- 10 C. And the inclination of the Equator over the orbit is of 3 degrees which simply means that Venus has no seasons. > Mark S. ------- ------------------------------ Date: 7 May 90 19:39:50 GMT From: zephyr.ens.tek.com!tektronix!sequent!crg5!gsmith@uunet.uu.net (Greg Smith) Subject: Re: space garbage Sorry if this was already covered in this thread, but my inquiring mind wants to know: Does anyone know what kind of survival procedure NASA has in place in the event of a suit puncture, during EVA, by 'space garbage' or other particles? Is there some type of automatic mechanism that would seal small holes? Also I would assume that judging by the degree of damage to the shuttle window caused by a very small particle, (was it a paint chip?) a similar collision during EVA would pass cleanly through the unlucky person in the suit, or is it somehow reinforced to stop most particles?

Yee) Subject: Payload Summary for 05/07/90 (Forwarded) STS-35 PAYLOAD STATUS REPORT MONDAY, MAY 7, 1990 -- 3 P.M. Patricia E. Phillips NASA Public Affairs/KSC 407/867-2468 ASTRO-1/STS-35 Payload operations toward the STS-35 flight continue at Launch Pad 39A. On second shift Sunday, the final pre-flight mass memory unit (MMU) subsystem load for Astro-1 was completed. This approximate five-hour operation included verification testing. Today, technicians will again renew the Broad Band X-Ray Telescope (BBXRT) liquid argon cooling. The next scheduled argon servicing will provide solidified argon, and will be completed at about L-61 hours before the launch of Columbia and her crew. The BBXRT coolant servicing has been designed to protect both the planned mission flight time for BBXRT, and also to provide the greatest amount of flexibility in the launch environ- ment. Based on current mission planning, the payloads team ap- proach will provide up to 6 launch opportunity days beginning 60 hours after argon servicing. Prelaunch operations will deplete about 2.5 days of argon, which, in a solidified form, will provide 16 days of cooling. With a possibility for a 10-day flight, 3.5 days remain for launch attempts. However, the primary science objectives for BBXRT can be accomplished in 8 flight days. Therefore, the mis- sion team has agreed to provide two additional launch opportunity days, if required. Those 2 days, plus the 3.5 days and the original launch day, provide the 6-window opportunity. The launch director and mission management team will determine the actual launch scrub/recycle, should any be required "The payloads team has done a really good job of responding to a demanding and rapidly-changing environment. We've met our timelines and were also able to work out a way to increase the launch opportunities while still protecting the science of BBXRT," said NASA KSC Payload Manager Glenn Snyder. Film installation in the Ultraviolet Imaging Telescope (UIT) will be accomplished about 5 days before flight. After flight, a specially-fitted platform will be used at Edwards Air Force Base to remove the UIT film. Astronaut Jeff Hoffman used this platform in the Orbiter Processing Facility to perform a fit check and also to verify that the film was readily accessible in case a spacewalk was required on orbit. Engineers and scientists have decided to upgrade the system's capability to maintain argon temperature, pressure, and venting by the addition of three pressure relief valves. The proposed change will increase the safety redundancy for nominal argon venting during on-orbit operations. At present, no impact is seen to the STS-35 launch schedule, since the operation can be performed on the pad in parallel with other activities. ------------------------------ End of SPACE Digest V11 #370 *******************
