I take it on faith that even though Quayle may occasionally garble his
message, he is still quite informed and intelligent.
In the case of his Mars comments, I think he was boiling a long
dissertation down for public consumption.

Interesting info on the DCY/DC-1 launch facilities. No need for the
massive VAB like the one at KSC. And with the miles of support roads
(or railway tracks in the case of the exUSSR's Baikonour Cosmodrome)eliminated.
I get the feeling that the launch pads could be more generic than existing
pads-KSC's 39A and B are only for the shuttle, Pad 41 (I think) is only for
Titan III's, etc.
Overall, the SSTO concept is most facinating.

Reply to Mary Shafer's message about the DC-X:
(stuff deleted)
My appologies for my lack of info on the DCX vehicle. I just assumed that
since it was referred to as a space vehicle that it woul go into space.
I had no idea the project was canceled.

MARS OBSERVER MISSION STATUS
October 23, 1992
The Mars Observer spacecraft is on the correct cruise
trajectory to Mars and all spacecraft subsystems are performing
well. Instrument payload and payload data checkouts are
continuing as planned.
The Magnetometer and Gamma Ray Spectrometer have been
successfully checked out. Testing of the Mars Balloon Relay
instrument took place on Sunday, Oct. 18, with excellent results.
The Mars Observer Camera underwent a focusing test on Oct. 20,
with similar results. Two other instruments, the Pressure
Modulator Infrared Radiometer and Thermal Emission Spectrometer,
also completed initial checkouts, and the Laser Altimeter was
checked out yesterday during a three-hour test. The first part
of this payload flight sequence will be completed tomorrow, Oct.
24.
Data from the Transfer Orbit Stage (TOS) was successfully
played back on the third attempt on Oct. 7, 1992. The Deep Space
Network reported that most of the TOS telemetry -- about one hour
and 16 minutes -- was recovered and recorded on the ground. A
preliminary review from the TOS program staff indicates that the
rocket motor and electrical systems performed well. A more
comprehensive evaluation is currently under way.
The spacecraft is scheduled to perform its second trajectory
correction maneuver, TCM-2, on Jan. 8, 1993.
Today the spacecraft is about 5 million miles (8 million
kilometers) from Earth, traveling at a speed of about 7,000 miles
per hour (11,000 kilometers per hour) relative to Earth. Its
velocity relative to the sun is about 73,000 miles per hour
(115,000 kilometers per hour).

Subject: re HRMS for ETI
Surely NASA must have some estimates of the probability of
success of it's HRMS.I've read of estimates ranging from almost
certain to impossible of finding other intelligent life in the
universe.Just cause the universe is so huge it doesnt mean that
life exists elsewhere.The Anthropic Principle speculates along
those lines.Could someone enlighten me on NASA's estimates
before they decided to undertake this project - both for the
Targeted Search and the Sky Survey. Some details of the
calculation taking into account astrophysics, evolution of
solar systems, biological science, evolution of life etc.
will be helpful.
Thanks.
