Live coverage: International Space Station crew lands in Kazakhstan

The Perseverance rover’s sterilized sample tubes — designed to seal Martian rock and sediment for eventual return to Earth — are installed on the spacecraft as teams at NASA’s Kennedy Space Center prepare to enclose the rover inside the payload shroud of its Atlas 5 launcher for liftoff July 20.

SpaceX’s first Falcon Heavy rocket took off on its inaugural test launch from NASA’s Kennedy Space Center in Florida at 3:45 p.m. EST (2045 GMT). The high-power launcher successfully boosted Elon Musk’s electric Tesla sports car into deep space as a shakedown for future Falcon Heavy missions.

NASA astronaut Jessica Meir took control of the International Space Station’s Canadian-built robot arm Monday to capture a Northrop Grumman Cygnus supply ship carrying crew provisions, spacewalking gear to repair an aging particle physics experiment, tech demo satellites for the U.S. military, and an oven to bake the first cookies in space.
