BEAM and Dragon Work, DNA Studies Before Station Lifts Orbit













ISS - Expedition 61 Mission patch.

It is back to work for the six-member Expedition 61 crew from the U.S., Russia and Italy after celebrating Christmas aboard the International Space Station. The space residents checked out BEAM and a commercial resupply ship and researched a variety of space phenomena.

NASA astronaut Andrew Morgan opened up the Bigelow Expandable Activity Module (BEAM) today for some housecleaning work. He and fellow NASA Flight Engineer Christina Koch relocated gear stowed in front of BEAM’s hatch and sampled the module’s air and surfaces for microbes. BEAM has been attached to the station since April 2016.

Koch then moved on to loading cargo inside the SpaceX Dragon cargo craft due to return to Earth on January 5. Flight Engineer Jessica Meir started the packing work today as the crew readies research results for splashdown in the Pacific Ocean aboard Dragon.

Meir also explored what microgravity does to genetics sequencing DNA samples with student-designed tools. Next, she ran a combustion experiment and observed how different samples burn and how flames spread in weightlessness.

Commander Luca Parmitano of ESA (European Space Agency) is also gathering hardware for return to Earth inside Dragon. He is packing the obsolete power and electronics gear retrieved during a series of spacewalks earlier this year. Engineers on the ground will analyze how years of exposure to the harsh space environment impacted the devices that powered multiple station systems.

Russia’s docked cargo craft, the Progress 74, will fire its engines twice beginning tonight to lift the station’s orbit to support Russian spacecraft activities in 2020. Cosmonauts Alexander Skvortsov and Oleg Skripochka readied the orbital lab today and shuttered windows for the orbital reboost.
