Video: Space station’s robot arm captures Dragon cargo ship

After a bit of a struggle with a balky bolt, space station commander Peggy Whitson replaced a failed external computer during a short, hurriedly planned spacewalk Tuesday while crewmate Jack Fischer installed a pair of antennas to improve wireless communications during future excursions.

NASA announced Monday that the launch of the first operational crew rotation mission to the International Space Station on SpaceX’s Crew Dragon spacecraft is set for the predawn hours of Halloween, eight days later than previously planned.

SpaceX launched a Falcon 9 rocket carrying 23 Starlink satellites at sunrise Monday, capping a busy long-weekend for the launch company that saw three launches and two scrubbed countdowns over four days.
