@Ghost in the Machine: I was aware of the existence of the original, in that I knew (a) it was about going inside a computer program and (b) there were lightcycles.

@swenson: To the best of my knowledge there are very good reasons for believing that dark matter is nonbaryonic. For instance - abundances of elements generated in Big Bang nucleosynthesis and cosmic microwave background data from WMAP. If the missing mass was baryonic - regular everyday matter - then the predictions…

@Trystero: There are some interesting bits in it. Mainly the parts about Mars Direct mission modes and In Situ Resource Utilization.

I thought it was a fun but very straightforward action heist movie. Definitely not the mindscrew I'd been expecting, but very entertaining and beautifully filmed.

@collex: I agree. The first one was nothing special, but it looked pretty and it was entertaining fluff.

@ceti: They're persistent little blighters too.

@99TelepodProblems: Cool pic!

@collex: Oh. My interest in this project has plummeted like an Apollo without heat shield or parachutes.

The real story is here:

@Stompy1: We can breathe quite a variety of mixes as long as the partial pressure of oxygen is okay and the buffer gases aren't toxic. For instance Apollo flights used pure oxygen at 5 psi (this was on my mind, as I watched Apollo 13 this evening!)

@Batmanuel: Yes. It's about -170C on Titan. You'd need an air supply and a heated environment suit.

@twophrasebark: Sorry for the buzzkill.

For anyone in the UK, there's a fascinating Cold War exhibit at RAF Cosford.

@SG-17: I believe they decreased the yield of the Tsar Bomba to prevent the fireball touching the ground, which would lead to huge amounts of fallout.

While Cassini's findings are fascinating, this article - primarily the headline and the first paragraph - could not be more misleading.

Well, they do look quite interesting.

@Ghost in the Machine: I really love that movie.

@Mysta: I highly recommend Permutation City.

@laughingacademy: Number 27 has been completely destroyed.
