Washington: Three members of the International Space Station’s Expedition 57 crew have returned to Earth safely after spending 197 days in space. The crew members — Sergey Prokopyev of the Russian space agency Roscosmos, Serena Aunon-Chancellor of NASA and Alexander Gerst of European Space Agency (ESA) — landed in Kazakhstan on Thursday, marking the end of a voyage that took them around the globe 3,152 times, covering 83.3 million miles.
The Expedition 57 crew members were launched on June 6 and arrived at the space station two days later to begin their mission. For the last 16 days of her mission, Aunon-Chancellor was joined by fellow NASA astronaut Anne McClain, marking the first time in which the only two US astronauts on a mission were both women, the US space agency said in a statement.
The Expedition 57 crew contributed to hundreds of experiments in biology, biotechnology, physical science and Earth science aboard the world-class orbiting laboratory. The 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.
