NASA is dreaming of methane oceans and asteroid nets. Each year the space agency solicits ideas for space technology that could prove useful in the next few decades. Here are five of the 12 projects chosen this year by the NASA Innovative Advanced Concepts (NIAC) programme . Each project will receive $100,000 for further development, plus the possibility of an additional $500,000.
The supermassive black hole is 40 million times as massive as the sun and powers a quasar that existed 700 million years after the Big Bang.
The asteroid zoomed by Earth at a perfectly safe distance of around 1.8 million miles (2.9 kilometers).
Images show surprise changes to the spacecraft as it interacted with the atmosphere.
