Video: Change of command aboard International Space Station

The composite structure of Sierra Nevada Corp.’s first space-rated Dream Chaser space plane has arrived at the company’s Colorado factory for integration with computers, a heat shield and mechanical systems before launch to the International Space Station in late 2021.

Leaving six crewmates behind in orbit, a Russian commander, his NASA co-pilot and a first-time flier from the United Arab Emirates undocked from the International Space Station early Thursday, executed a fiery plunge back to Earth and landed safely on the steppe of Kazakhstan.

In a rapid-fire crew rotation, a NASA astronaut and two Russian cosmonauts are packing up for the trip back to Earth Saturday, leaving the International Space Station just eight days after the arrival of another three-person crew and three weeks before their own replacements arrive to boost the lab’s crew back to six.
