Live coverage: Soyuz crew lands in Kazakhstan

NASA has selected Axiom Space, a Houston-based startup partnering with Boeing and other aerospace contractors, to attach a commercial habitat to the International Space Station and begin constructing an orbiting complex that the company says could ultimately replace the international research outpost.

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 hoisted its Falcon 9 rocket upright Sunday evening, hours before launching on a commercial resupply mission to the International Space Station. Technicians installed time-sensitive supplies into the Dragon cargo capsule earlier in the day.
