Photos: Atlas 5 rocket aims for International Space Station

Astronauts Christina Koch and Jessica Meir carried out history’s first all-female spacewalk Friday, floating outside the International Space Station and successfully installing a 230-pound replacement battery charger in the lab’s solar power system. The historic excursion was carried out in a blaze of public interest that rose all the way to the White House.

Firefly Aerospace and Aerojet Rocketdyne have announced a strategic partnership to collaborate on rocket propulsion, an agreement that could lead to Firefly’s use of Aerojet’s AR1 engine in a new medium-lift launcher.

A logistics-delivery vessel for the International Space Station, launched and operated privately by commercial companies on behalf of NASA, is scheduled to arrive at the lab complex Saturday at 6:05 a.m. EDT (1005 GMT).
