Also, where can I find information on the experiments that will be performed on this mission? PI's, equipment, maybe even some idea of what, exactly will be done, coporate sponsors, etc. I have access to the ames SPACE archive, if that helps. Many thanks.

This does not happen in normal air because oxygen is only about 20% of the air we breath. Therefore the partial pressure of oxygen at sea level is about (14 psi * 0.2) or about 2.8 psi. This is about the same oxygen partial pressure as is in the EVA suits used by the shuttle. Therefore the shuttle astronaut in an EVA suit is getting about the same amount of oxygen as he would at sea level on earth, but without all the other gases that are in our atmosphere, mostly nitrogen. Anyway, the oxygen pressure in a shuttle EVA suit is well below the toxic level.

The idea of Terraforming Venus is quite a challenge, but it is of only a limited interest to me since it would take thousands of years to complete such a task. The only thing I would like to add to the discussion here is that it is extremely dangerous to try to send comets on this planet (of Love... :-) ), for many of this stuff can reach the Earth, and the kinetic energy contained brought in by such a meteorite when it crashes at 12 to 100 km per second is sufficient to vaporize it hundreds of times (remember what happened in Siberia in 1908, was there really some kind of cooling down?). In other words we will WARM UP Venus instead of cooling it. And beside, I don't see we should disfigurate the venusian landscapes with craters. For God's sake, ALL the solid objects in our solar system (except Venus and Earth) are SURSATURATED with those boring, destructive round circles, so please, DON'T DESTROY THE BEAUTIE OF VENUS!!!!!

No, several female astronauts have flown. However, all this talk about whether or not there has been sex in space is pretty silly.

It operates in three different modes: ---------------------------------------------------------------------- Resolution(*) Field of View Bandpass Limiting Magnitude R=10^5 0.25 to 2.0 arc sec 1100-3200 A 11 R=2 x 10^4 0.25 to 2.0 arc sec 1100-3200 A 14 R=2 x 10^3 0.25 to 2.0 arc sec 1100-1700 A 17 Lambda (*) Resolution is indicated by R= ------------ , so that in the high delta Lambda resolution mode, R=10^5 corresponds to a resolution of 0.011A at 1100A ---------------------------------------------------------------------- The various resolutions and bandpasses are achieved using 6 different gratings, ranging from a 6000 line/mm holographic to a 316 line/mm echelle grating, which can use either of two cross-dispersers. Exposure lengths as short as 200ms, and the shortest interval allowed between integrations is 50ms. The detectors used are 512 channel Digicons, essentially pulse-counting diode arrays (i.e. antiques), which have quantum efficiencies in the 10-15% range. There are two Digicons, one a CsI/LiF device intended for use from around 1100 to 1500 A, and a second CsTe/MgF2 device which is sensitive from about Lyman-alpha to 3200A, although its sensitivity is low in the UV. The HRS also has plane (non-dispersive) optics for use in target acquisition. There are four mirror/plate combinations which allow acquisition of targets ranging from magnitude V=-1 to V=+21. The scientific goals of the instrument are very wide-ranging. Proposals granted time at this point deal with topics including accreting binaries, interstellar medium, stellar winds, and Local Group galaxies.

Hyperdrive, yes, but the Puppeteers were indeed involved. In a later book, it was pointed out that the Puppeteers had probably directed a star seed, which the Outsiders follow, toward We Made It so that humans would be able to get the drive before the Kzinti.

At high pressure there is serious danger, and even at one atmosphere there is some small risk I believe.
