I've just finished Steve Squyres' _Roving Mars_, and can't recommend it highly enough. It really gets across the nuts and bolts -- and the emotional...

What was the total mass (w/ fuel) of the LEM, CM and SM? In other words, how much gross payload had the S-IVB put into translunar injection when it separated?...

I read recently that there is a great need for several tons of lunar regolith simulant. What would be required for someone to supply that need? How hard is it...

Pretend a hypothetical SSTO tops off its tanks in low Earth orbit. It now has plenty of fuel to get from LEO to the lunar surface. In fact, it has 4000m/s of...

The Lunar Lander has always fascinated me. The first (and only) manned spacecraft to land on another world. Not being a part of that part of history, I don't...

Here's an article that says scientists have used nanotubes to improve on gecko-like...

Is is possible to make it into earth orbit using a sub-G thrusting rocket motor together with a hypersonic lifting body? Assuming it is possible Newtonically,...

space cobwebs Looks like good news on producing fibers with the strength of spider silk, in quantity, for constructing the support member for that elevator...

I'm new here so bear with me.. I have a question regarding NOX nitrous oxide is RP-1 soluble in it while the NOX is a liquid? or what hydrocarbon is soluble in...

(Please excuse double post - I also sent this to sci.space.history) Hi all I've seen lots of spectacular images produced by the various Mars rovers and their...

Could someone direct me to a text version (ie regular Word text) of a 'pulse high' symbol? I've been looking everywhere but it's quite difficult. Thank you.

Could Hubble, along with the NexGen space telescope operate as a long baseline optical interferometer in some way? Perhaps a reference laser beam could be...

I noticed on Boeing's viewgraph of future Delta IV upgrades a mention of "cross-feed", which I took to mean propellant transfer between common core boosters in...

Oops... The Arcam EBM S12 fabrication speed is only about 17 cubic millimeters per second, but its scanning speed is 1 km/s. A much more powerful electron gun...

I am looking for data on the actual CG locations for flown lifting re-entry capsules. References/pointers/whatever appreciated. Thanks. -george william...
