Video: Change of command aboard International Space Station

These images show the liftoff of SpaceX’s Crew Dragon Resilience spacecraft on top of a 215-foot-tall Falcon 9 rocket from pad 39A at NASA’s Kennedy Space Center in Florida, carrying four astronauts on an expedition to the International Space Station.

Something went wrong with a Russian Progress cargo spacecraft moments before it deployed into orbit Tuesday on the way to the International Space Station, and investigators are analyzing whether the stricken supply ship may have lost control after a botched separation from its Soyuz rocket booster.

In a major shakeup at NASA Headquarters, agency Administrator Jim Bridenstine said Wednesday that Bill Gerstenmaier, the widely respected director of human spaceflight, has been replaced in the midst of an ambitious push to meet the Trump administration’s directive to send astronauts back to the moon within five years.
