Three members of the International Space Station’s Expedition 57 crew, including NASA astronaut Serena Auñón-Chancellor, returned to Earth Thursday, safely landing at 12:02 a.m. EST (11:02 a.m. local time) in Kazakhstan.
Auñón-Chancellor and her crewmates, Expedition 57 Commander Alexander Gerst of ESA (European Space Agency) and Soyuz commander Sergey Prokopyev, launched June 6 and arrived at the space station two days later to begin their mission.
The Expedition 57 crew contributed to hundreds of experiments in biology, biotechnology, physical science and Earth science aboard the world-class orbiting laboratory. Highlights included investigations into new cancer treatment methods and algae growth in space. The crew also installed a new Life Sciences Glovebox, a sealed work area for life science and technology investigations that can accommodate two astronauts.
During the 197 days, they circled the globe 3,152 times, covering 83.3 million miles. This was the first flight for Auñón-Chancellor and Prokopyev and the second for Gerst, who – with a total of 362 days in orbit – now holds the flight duration record among ESA astronauts.
