NASA outlines recommendations to clear path for Boeing to resume Starliner flights
NASA has completed an exhaustive review of software problems and procedural oversights that prevented an unpiloted Boeing Starliner capsule from docking with the space station last year. The agency is implementing 80 recommendations to clear the way for a second test flight later this year and, if all goes well, Boeing's first piloted flight next spring, officials said Tuesday.

Spacewalkers complete another round of battery replacement work
Picking up where they left off last week, two space station astronauts ventured back outside the outpost Wednesday to continue the replacement of aging batteries in the lab's solar power system. Two more spacewalks later this month should complete the multi-year project.

NASA delays Mars rover launch to no earlier than July 30
A technical issue with the United Launch Alliance Atlas 5 rocket that will send NASA's $2.4 billion Perseverance rover toward Mars has pushed the mission's launch date back to no earlier than July 30, nearly two weeks into a month-long window for the rover to head to the Red Planet, or else face a two-year delay.

Cassidy, Behnken begin final series of space station battery upgrades
Two astronauts floated outside the International Space Station early Friday for the first of four planned spacewalks to wrap up a complex multi-year job to replace 48 aging batteries in the lab's solar power system with 24 more powerful lithium-ion units.

Astronauts gear up for Friday spacewalk amid planning for August Crew Dragon return
Space station commander Chris Cassidy and Robert Behnken plan to float outside Friday for the first of up to four spacewalks needed to complete the replacement of aging batteries in the lab’s solar power system. NASA managers hope to get the work done in time for Behnken and crewmate Douglas Hurley to return to Earth aboard their Crew Dragon capsule by around Aug. 2, officials said Wednesday.

Launch of NASA’s Perseverance Mars rover delayed to July 22
