Mankind could leave its first footprints on Mars sometime in the 2030s. And if we want to get there, we’re gonna need a new ride. That’s why NASA’s building the Space Launch System (SLS), a heavy lift vehicle that’s intended, eventually, to carry astronauts into deep space.
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.
