Live coverage: International crew lands in Kazakhstan

SpaceX test-fired a Falcon 9 rocket Saturday at Cape Canaveral, a critical test before liftoff Wednesday with several tons of cargo heading to the International Space Station.

NASA astronaut Nick Hague will take the place of Anne McClain on a spacewalk Friday outside the International Space Station, teaming up with crewmate Christina Koch  to continue a series of battery upgrades on an excursion that would have been the first all-female spacewalk in history.

Two astronauts floated outside the International Space Station Sunday for the first in a series of spacewalks to upgrade the lab’s aging solar power system, assembling a support fixture that eventually will hold a new solar blanket.
