The Bigelow Expandable Activity Module’s (BEAM) hatch was opened up for the first time today. Astronaut Jeff Williams entered BEAM and checked sensors, installed air ducts and reported back to Earth that it was in pristine condition. After Williams completed the BEAM checks he exited and closed the hatch for the day.

The crew will enter BEAM a couple of more times through Wednesday to check sensors and gear. BEAM will stay attached to the International Space Station for two years of tests of its durability.

The rest of the Expedition 47 crew moved right along with human research studies benefiting astronauts in space and people on Earth. British astronaut Tim Peake explored how astronauts adapt to tasks requiring high concentration and detailed procedures. Williams later collected biological samples for stowage and analysis for the Multi-Omics experiment that is studying the immune system.

Commander Tim Peake and Flight Engineer Yuri Malenchenko are packing their Soyuz TMA-19M spacecraft and getting ready for a June 18 departure. Peake will join the duo for the ride home after living in space for six months.
