Full disclosure: I will definitely be seeing The Martian anyway because it comes out right before my birthday and I loved the book. But this new trailer thingy with Neil DeGrasse Tyson in it is really excellent:

I also read a couple of interesting pieces about the movie over the weekend:

• At Popular Science, “Why NASA Helped Ridley Scott Create ‘The Martian’ Film”
• At Computer World, “7 real NASA technologies in sci-fi movie The Martian“
• At Outer Places, “Space Advocates Hope to Use The Martian Movie to Encourage Political Support for Future Mars Missions”
