It is travelling around the Sun at a speed of almost 69,000 mph, and it has gone almost 391 million miles since launch. The spacecraft health continues to be excellent. Current activities include routine Sun-pointing about every other day, and other housekeeping tasks. Science activities include measurements of the interplanetary environment by the magnetometer, dust detector, and ultraviolet instruments, which are stored in a computer memory and read out to the Earth about twice a week. The Galileo flight team is preparing for the next trajectory correction maneuver, scheduled for Friday and Saturday, May 11-12.

Rosenthal "An error by a ground controller put the Hubble Space Telescope to sleep again overnight but the $1.5 billion instrument was re-awakened Wednesday and was functioning normally again." The telescope went into a "safe-mode" when the 10- foot diameter aperture cover closed and its motion triggered the shut-down. Ground controllers failed to tell the telescope not to close its protective cover during a test, the AP reported. NASA said the spacecraft operated just as it should for 72 hours without ground control and it has now functioned three times: When the door was first opened, when an errant cable caused resistance to one of the the high-gain antenna's movements and the during the latest test. While 10 hours in the lengthy start up process were lost, no delay was expected in getting the first pictures from the telescope early Saturday. The AP reported NASA saying that "problems of that nature are ex- pected during a start-up process that will take more than six months before the first real scientific re- turns."

The "golden disc" on VOYAGER 1 and 2 (which houses the Interstellar Record) has no such engraving on it. On the PIONEER plaque, there is a representative nude male and female human drawn in front of a schematic of the PIONEER probe (to help indicate our size in relation to the craft). The man is exten- ding his right arm upward in what will hopefully be interpreted by whomever finds the spacecraft as a friendly salutation. The woman is standing next to him with both of her arms down. The plaque's designers did not want both people to raise there arms, lest the beings who find it (presumably non-human) think that all humans have their right arms in that position. In one of the images on the VOYAGER record, though, there is a reproduction of the nude man and woman from the PIONEER plaque, but this time it is the woman who is raising her arm in greeting and the man who is "merely" standing there. PIONEER 10 was launched to Jupiter in 1972. PIONEER 11 was launched to Jupiter and Saturn in 1973. VOYAGER 1 and 2 were launched to study Jupiter, Saturn, Uranus, and Neptune in 1977.

However, the list of unknowns was fairly old. I believe that planetary science has moved on, and the list must now be longer. For example: Bombardment: Earth gets occasional hits from major solid objects. This can have a major effect on evolution - both by destruction, and by allowing minority creatures (mammals?) to move into previously filled niches. What would be the effect of more bombardment, or of less? Gee, good question. Magnetic field: This shields us from a lot of solar radiation. Is the Earth's field unusual? Who knows? It seems to have a connection with: Continental Drift: This is important because it recycles the ocean floor. Neither Mars nor Venus have continental drift, so we can't blithely assume that it's common on rocky planets. Solar stability: Perhaps Sol is unusually quiet. If its output were to grow or to shrink by various percentage points, then the Earth's biosphere-as-we-know-it would collapse. So, long-term stability is important.

You know that its the hottest terrestrial planet? Do you know that the longest any UNMANNED craft has survived is a few hours? The Russians have been sending their Venera landers there for years. The best they've been able to do is 46 hours with Venera 16 (Vega 2) in 1985. What makes you think that we could withstand the 460C temperatures that machines could not? >- The athmosphere of Venus has the same quantity of oxygen as here. It's not the oxygen. Venus's atmosphere is composed of 3.5% Nitrogen, as opposed to Earth's 80%. What little oxygen there is shares the same 5% of Venus's atmosphere as the sulfuric & hydrochloric acid present. And, lest we forget, 96% CO2! If that wasn't enough, recall that the clouds on Venus are made up largely of sulphuric acid. Of course, if you *do* find someone to build you a suit to withstand that, it will have to withstand an atmospheric pressure 90 times that of Earth. If you find one of those, it might be wiser to sell it to alt.flamers......

What is the feasiblity and possibility of working a shuttle rendezvous to pick up a satellite which has been in orbit for quite a while? Maybe there are a couple of old Big Birds which would be nice to deorbit? ALSO, what would be be possibility of "flying back" an old space probe into LEO, rather than letting them drift around for years and years. You'd need some propellant leftover and some communications capabilities to tell it what to do, but I'm amazed as to what one can do with a couple of large planets for assistance....
