Watch live as Elon Musk unveils his vision for missions to Mars

A SpaceX Falcon 9 rocket booster descended under engine power to a floating landing platform in the Atlantic Ocean on Friday, notching the first-ever rocket landing at sea minutes after liftoff from Cape Canaveral with a supply ship hauling 3.5 tons of cargo to the International Space Station.

On the eve of its blazing entry into the Martian atmosphere, NASA’s InSight spacecraft briefly pulsed its control jets Sunday to target a safe, flat landing zone near the planet’s equator — the last in a series of trajectory correction maneuvers since the mission’s launch in May.
