Here, an article about the feasibility of designing a space station like the one in "Elysium." Quote:
"The premise is totally believable to me. I spent 28 years working on NASA's International Space Station and retired last summer as the director of ISS at NASA Headquarters," Mark Uhran, former director of the International Space Station Division in NASA's Office of Human Exploration and Operations, said. "When I took a look at the Elysium space station, I thought to myself, that's certainly achievable in this millennium."
And here, an article about NASA scientists trying to test a theory on the origins of life on Earth. Quote:
Imagine Earth 4 billion years ago. The world was covered in an acidic ocean, its bottom studded with mineral chimneys or hydrothermal vents. These were not ordinary chimneys. They had pores that allowed selective molecules to pass through, setting up a chemical gradient.
The vents were the origins of all life on earth, according to a 25-year-old theory proposed by Mike Russell, a research scientist at NASA’s Jet Propulsion Laboratory, that is gaining traction in the astrobiology community. NASA’s Astrobiology Institute has invested $8 billion in proving the theory.
