I don't think they're massive enough to cause large tides, but they might be worth incorporating into a calendar for other reasons. Or not.

The satellite has been stabilized into about a 270 nmi orbit at 28.5 deg inclination. Expected duration of the satellite at this altitude is greater than 2000 years, assuming a 2500 pound cylindrical satellite, with a 12 foot diameter and the standard atmosphere - atmospheric effects at solar max may decrease this duration. (Reference: Ginsberg & Luders, "Orbit Planner's Handbook", 1976). Potential missions to retrieve Intelsat VI satellite are estimated from the latest shuttle manifest (January) using the assumptions of: 1) minimal flight manifest impact, 2) missions must be in 160 nmi altitude range at 28.5 deg inclination, 3) no bumping of DoD missions, 4) no consideration of use on spacelab missions.

That's the way the countdown is moving along with Goddard's Pegasus satellite, now scheduled for launch from a B-52 on April 4, according to Project Manager Bob Pincus. The two live barium canisters were attached to the payload last Thursday, Pincus explained, and they were mated with Pegasus on Friday. Plans call for some further ground tests this week, he explained, plus closing out on the thermal blankets and installing the fairing. The B-52 will carry the three-stage rocket and payload under its right wing and climb to 42,600 feet (12,900 meters) where it will drop the rocket and payload some 50 miles off the coast of California just west of Vandenberg Air Force Base. The NASA B-52 is scheduled to takeoff at 2:08 Eastern Time and make the drop an hour later at 3:08 p.m., Pincus said.

I don't expect there to never be cost overruns, or delays, or innocent errors, or even total failures. What I *do* want is honesty. NASA (read: upper level NASA bureaucracy) wasn't being honest with the public about the shuttle's expected failure rate or reasonable flight rate. Lou's attempt to blame the defrauded public for this was shameful. Paul F.

Correct. The TA is Towed Array, meaning that a ship pulls a structure, and the structure has a whole bunch of hydrophones on it. I forget what the rest stands for (it's been 15 years) but SUR is probably SURface, and S is Sonar or Signal or System or Something. Basically, the signal processing does synthetic-aperture type calculations, using phase information from the array. I recall they were worried about how to factor in the geometric distortions caused by the structure's flex. Yes, the U.S. Navy (more specifically, the submarine/antisubmarine branches) didn't really want foreign navies to have good underwater charts. -- Don D.C.Lindsay Carnegie Mellon Computer Science ------------------------------ Date: 28 Mar 90 09:25:16 GMT From: trident.arc.nasa.gov!yee@ames.arc.nasa.gov (Peter E.

N90-18 NOTE TO EDITORS: B-52/PEGASUS LAUNCH SCHEDULED FOR APRIL 4 First mission of the Pegasus air-launched space booster is now scheduled for April 4. Pegasus will be launched from underneath the wing of a B-52 aircraft operated by NASA's Ames- Dryden Flight Research Facility, Edwards, Calif. Pegasus is a three-stage space launch vehicle designed to deliver small payloads into low Earth orbit. Payloads for the first mission include PEGSAT, which carries instrumentation, a small satellite and barium chemical release experiments. The Pegasus program is sponsored by the Department of Defense Advanced Research Projects Agency. Pegasus was developed by Orbital Sciences Corp., Fairfax, Va., and Hercules Aerospace Co., Wilmington, Del. Launch will take place about 60 miles southwest of Monterey, over the Pacific Ocean. The event will be carried live on NASA Select television, Satcom F-2R, transponder 13. There will be a post-mission press briefing, also carried on NASA Select, at the Ames-Dryden facility. Media will be able to photograph takeoff of the B-52/Pegasus. Takeoff time is planned for 11 a.m. PDT, with launch at about 12:10 p.m. PDT. Media wishing to cover the mission should contact the Ames- Dryden Public Affairs Office, 805/258-8381, no later than April 2. Media who plan to photograph takeoff must be at the Dryden News Center no later than 9:45 a.m. PDT on launch day. ------------------------------ End of SPACE Digest V11 #196 *******************
