High tech wealthy civilisations might see terraforming Venus as a desirable luxury [not lots sillier than having several hundred shoes, or a $10,000 dog house]. I could also imagine a noisy group of social misfits being handed a new 'eden' to fill a demand for a 'natural' style homeland. The bottom of a gravity well in 720 K, 90 bar CO2 and corrosive chemical soup might strike a gov't as a fine place for refusniks to go [perhaps with life support :) ].

That would increase the cost considerably. Magellan will arive at Venus in 3 months and do the above mentioned mapping. Manned mission can be more useful on other projects. For example, the scientific benefits from a manned lunar base would be well worth the costs.

Both instruments are located in Columbia's payload bay and will be operated during 12-hour shifts by the crew. Liftoff of the 10th flight of Columbia is scheduled for 12:45 a.m. EDT on May 17 from launch pad 39-A at the Kennedy Space Center, Fla. Columbia will be placed into a 218 statute (190 nautical) mile circular orbit, inclined 28.5 degrees to the equator. Nominal mission duration is expected to be 8 days 19 hours 55 minutes. Deorbit is planned on orbit 139, with landing scheduled for 8:40 p.m. EDT on May 25 at Edwards Air Force Base, Calif. Columbia's middeck will carry the Shuttle Amateur Radio Experiment (SAREX) to communicate with amateur radio stations within line-of-sight of the orbiter in voice mode or data mode. This experiment has previously flown on STS-9 and STS-51F. Also on this mission, Columbia will function as the subject for ground sensor operations as part of the Air Force Maui Optical Site (AMOS) calibration test. Commander of the seven-member crew is Vance Brand. Pilot is Guy Gardner. STS-35 is Brand's fourth trip to space. He previously flew on the Apollo-Soyuz Test Project mission in 1975. He also commanded Shuttle missions STS-5 in November 1982 and STS-41B in February 1984. Gardner previously piloted STS-27 in December 1988. Mission Specialists are Mike Lounge, Jeffrey Hoffman and Robert Parker. Lounge previously flew on STS-51I in August 1985 and STS-26 in September 1988. Hoffman flew as a Mission Specialist on STS-51D in April 1985. Parker's previous spaceflight experience was STS-9 in November 1983. Payload Specialists Ronald Parise and Samuel Durrance round out the STS-35 crew. Both are making their first space flights. * STS-35 QUICK LOOK * ===================== Launch Date: May 17, 1990 Launch Window: 12:45 a.m. - 3:09 a.m. EDT Launch Site: Kennedy Space Center, Fla.

SAREX communicates with amateur stations in line-of- sight of the orbiter in one of four transmission modes: voice, slow scan television (SSTV), data or (uplink only) fast scan television (FSTV). The voice mode is operated in the attended mode while SSTV, data or FSTV can be operated in either attended or unattended modes. During the mission, SAREX will be operated by Payload Specialist Ron Parise, a licensed operator (WA4SIR), during periods when he is not scheduled for orbiter or other payload activities. At least four transmissions will be made to test each transmission mode. Ronald A. Parise, 38, also will serve as a Payload Specialist. Parise is a senior scientist in the Space Observatories Department, Computer Science Corporation in Silver Spring, Md. He is a member of the research team for the Ultraviolet Imaging Telescope, one of the instruments scheduled for flight as part of the Astro payload. He is from Warren, Ohio. Parise has participated in flight hardware development, electronic system design and mission planning activities for the Ultraviolet Imaging Telescope project. He is pursuing his astronomical research interests with the International Ultraviolet Explorer satellite under a NASA grant. He received a bachelor of science degree in physics, with minors in mathematics, astronomy and geology from Youngstown State University, Ohio, and a master of science degree and a doctor of philosophy degree in astronomy from the University of Florida. The primary pair of frequencies intended for use during the mission is 145.55 MHz as the downlink from Columbia, with 144.95 MHz as the uplink. A spacing of 600 KHz was deliberately chosen for this primary pair to accommodate those whose split frequency capability is limited to the customary repeater offset. SAREX crew-tended operating times will be dictated by the time of launch. As a secondary payload, SAREX will be operated by Parise during his pre- and post-sleep activities each day. This means that wherever the Shuttle is above Earth during those operating windows, amateur stations can communicate with Columbia. Currently, those windows provide coverage for Australia, Japan, South America and South Africa. The continental United States has little or no coverage except through a network of ground stations in other parts of the world in conjunction with relay links back to the United States. Another part of the SAREX is the "robot," providing an automated operation which can proceed with little human intervention. The robot will generally be activated during one of the crew-tended windows and deactivated during the next one. This gives approximately 12 hours on and 12 hours off for the robot, with the operational period chosen to cover all of the U.S. passes. SAREX has previously flown on missions STS-9 and STS- 51F in different configurations, including the following hardware: a low-power hand-held FM transceiver, a spare battery set, an interface (I/F) module, a headset assembly, an equipment assembly cabinet, a television camera and monitor, a payload general support computer (PGSC) and an antenna which will be mounted in a forward flight window with a fast scan television (FSTV) module added to the assembly. Antenna location does not affect communications and therefore does not require a specific orbiter attitude for operations. The equipment is stowed in one middeck locker. SAREX is a joint effort of NASA and the American Radio Relay League (ARRL)/Amateur Radio Satellite Corporation (AMSAT).

One suggestion was to fly by Venus first and/or (?) this way either reduce the one way trip time to Mars or get an earlier return window to earth. That means if you add an additional planet to your trip, you save time, pro- pellant, and money.
