For the record, Feynmann also thought that besides the problem with
the solids that was fixed he thought there were other problems, such
as with the SSME's. He talked about this in _What Do You Care What
Other People Think?_ Even without that, it's worth a read.

Erich Von Daeniken ("the ancient gods were astronauts from other worlds") and
Andrew Thomas would absolutely LOVE your theory. Perhaps you should write a
book on the subject: how about "Aliens Ate My Saturn V"?

In the interest of upholding our Prime Directive, we must categorically deny
that we took any part in making the Saturn V, or that Chariots has any
correlation to reality...

Anyhow, *YOU'RE* the aliens, not us...  :) :)

The Korabl Sputnik series were unmanned Vostok spacecraft; the three

          KSC Release No. 32-91

          GROUNDBREAKING FOR KSC SPACE STATION FACILITY SLATED FOR MARCH 26

          KENNEDY SPACE CENTER,  FLA.  --  A  groundbreaking  ceremony  for
          NASA's  Space  Station Processing Facility (SSPF) will be held at
          10 a.m., Tuesday, March 26.

          Featured speakers for the ceremony include NASA's  Associate  Ad-
          ministrator for Space Flight Dr.  William B. Lenoir, KSC Director
          Forrest S.  McCartney,  Space Station  Freedom  Director  Richard
          Kohrs, KSC Space Station Project Office Manager Dick Lyon and KSC
          Director  of  Engineering Development Walt Murphy.   The ceremony
          will take place at the construction site in  the  KSC  Industrial
          Area, just east of the Operations & Checkout Building.

          The  SSPF will be a KSC-operated facility occupied by about 1,000
          NASA and contractor employees.  The three-story SSPF will include
          communications and electrical control areas, laboratories, logis-
          tics staging areas, operational control rooms, office areas and a
          cafeteria.   The SSPF will have over 63,000 square feet of  dedi-
          cated payload processing space, which includes a high bay and in-
          termediate bay.   A 5,000-square-foot airlock will be adjacent to
          the primary processing area.   Both the  airlock  and  processing
          area will be 100,000 parts-per-million-rated clean rooms.

          The  SSPF  is the biggest new construction facility undertaken at
          KSC since the Apollo era.

          The building was designed by Jacobs Engineering  Group,  Inc.  of
          Lakeland,  Fla.  and  will be constructed by Metric Constructors,
          Inc. of Tampa, Fla.  The building's cost is $56,215,000.

          News media wishing to cover the ceremony should  be  at  the  KSC
          News Center by 9:15 a.m. Tuesday, March 26, for transportation to
          the ceremony site.   Media representatives with permanent creden-
          tials may drive directly to the News Center.   Those who  require
          access  badges  should contact the News Center at 407/867-2468 to
          arrange access.

                        MAGELLAN STATUS REPORT
                           March 14, 1991

     The Magellan spacecraft is performing nominally.   All of the STARCALS
(star calibrations) and DESATS (desaturations) yesterday were successful.

     Last night a command was sent to the spacecraft to switch from
Transmitter B to A.  This appears to have cleared up the X-band communications
problem.  This morning a good signal-to-noise ratio of 8.4 on the high rate
data was observed.

     During the reconfiguration of AACS (Attitude and Articulation Control
Subsystem) Memory B yesterday, some alarms were noted when controllers reset
the off-line power flag.  Specifically, the heartbeat loss counter was
incremented and there was an indication of an attempt by the AACS computer to
access write-protected memory.  So the spacecraft controllers decided to put
the off-line power flag to its prior setting and delay the reactivation of
AACS Memory B until the reason for the alarms can be analyzed.

     No spacecraft commanding is planned for today.  Tomorrow, the upload of
tweak P1075, with the updates of the radar control parameter and mapping
quaternion files is planned.

Jonathan's Space Report

Mar 11 1991 (no.67)
----------------------------------------------------

Launch of STS-37/Atlantis and the Gamma Ray Observatory
remains due for early April.

Viktor Afanas'ev and Musa Manarov continue in orbit aboard the
Mir/Kvant/Kvant-2/Kristall/Soyuz TM-11/Progress M-6 complex.

An Ariane 4 rocket successfully orbited two satellites on Mar 2.
Astra 1B is a TV broadcasting satellite owned by the Luxembourg
based company SES (Societe Europeene des Satellites).
MOP (Meteosat Operational Programme) 2 is a European geostationary
weather satellite and will probably be renamed Meteosat 5 now
that it is in orbit. It is operated by ESA for the EUMETSAT
(European Meteorological Satellite Organization). The Arianespace SA
Ariane rocket is launched from the ESA base at Kourou in Guyane;
the third stage enters an elliptical geostationary transfer orbit
(GTO) with a perigee of a few hundred km and an apogee of 36000 km.
The two satellites separate from the third stage, and then once
at apogee ignite their internal rocket motors (a European MAGE rocket
for Meteosat, and probably a Thiokol Star 30 for Astra), putting
them in approximately circular equatorial 24 hour orbits. Small
thrusters are used to put the satellites in near exact stationary
orbits once they have drifted to the right longitude.

The 27th Raduga geostationary communications satellite
was launched on Feb 28 by 4-stage Proton from Baykonur.
Raduga is a C-band comsat for relay of telephone and TV
transmissions, first launched in 1975 for the Soviet
Ministry of Communications.

A Delta II 6925 launch vehicle placed the INMARSAT II F-2
satellite in geostationary transfer orbit on Mar 10.
INMARSAT is the International Maritime Satellite Organization.
The INMARSAT satellites provide L-band mobile communications
links for ships, aircraft and vehicles. The first INMARSAT II
was launched last year. There were no INMARSAT I satellites;
previously INMARSAT leased the MARECS satellites from ESA,
the MARISAT satellites from Comsat General Corp., and the
MCS transponders on the INTELSAT VA satellites.

10 years ago:  12 Mar 1981  Vladimir Kovalyonok and Viktor Savinykh
reached orbit in Soyuz T-4. They were the last long stay crew aboard
the Salyut 6 space station, remaining there for two and a half months.

20 years ago:  3 Mar 1971  The second Chinese satellite, Shi Jian,
was launched by a Chang Zheng 1 rocket. Its transmitter operated
for 8 years.

30 years ago: 9 Mar 1961. Korabl'-Sputnik-4 was launched by Vostok rocket
from Baykonur on one of the final unpiloted test flights of the Vostok
spaceship. The cabin, containing guinea pigs, mice, insects, and a
dog called Chernushka, was recovered after one orbit.

Especially when you think about the peak heating and peak aero loads
for a projectile thrown from the surface with enough energy to reach
orbit.  Simply put, it would burn up before it got there.  Railguns
would be great in a vacuum, though, at least in principle.  Now all we
need is the ability to get up there and use them....

Subject: Delta-Vee's around the solar system wanted


    I'm doing some trajectory calculations for various orbits involving disposal of nuclear waste, and I'm wondering if there is anybody out there with the following numbers already calculated.  If there is, I would appreciate it greatly if you could E-mail them to me at [e-mail].  The delta-vees I'm looking for specifically are:

    a) Direct escape from LEO to outside the solar system

    b) Escape from the solar system from LEO using a flyby of Jupiter

    c) Collision trajectory with the sun, direct from LEO

    d) Collision with sun from LEO, using a Jupiter flyby

    There were several other suggestions for trajectories to calculate, such as Oberth escapes from the solar system using a burn at Earth and another at perihelion, (possibly including a Jupiter flyby) but these were decided against by the group.

    If anyone has any ideas about means of getting rid of nuclear waste, or orbit information (delta-vee's, optimum trajectores, etc) that they think I might find useful, I would greatly appreciate it if they could please E-mail them to me soon.

    Thanks!
