As the International Space Station orbits Earth with three occupants already onboard, on the ground below in Baikonur, Kazakhstan, three more crewmates are engaged in activities leading up to a March 21 liftoff on a Soyuz MS-08 spacecraft to join them. (You can watch this launch live on NASA TV, with coverage beginning at 12:45 p.m. EDT.)
Today the future Expedition 55-56 crew members, NASA Flight Engineers Ricky Arnold and Drew Feustel, along with Soyuz Commander Oleg Artemyev, engaged with journalists for media day, sharing how they will continue work on hundreds of experiments in biology, biotechnology, physical science and Earth science aboard humanity’s only permanently occupied microgravity laboratory. This crew will build on the trend of long-term increase in U.S. crew size from three to four, allowing NASA to maximize time dedicated time for investigative research.
Meanwhile, off the Earth, the Expedition 55 crew reconfigured the JEM Airlock in support of an upcoming experiment: Materials on ISS Experiment – Flight Facility (MISSE-FF) payload operations. This study exposes sample plates containing a variety of surface materials to the harsh environs of space outside the station for varying durations. Data collected will inform satellite designers how different materials can degrade over time—a topic of great importance when it comes to designing and building spacecraft and structures to withstand a journey through the cosmos.
On Friday, Flight Engineer Scott Tingle of NASA will wrap up the week talking to science teachers—and lots of them—via an educational in-flight event with the National Science Teachers Association National Conference. During this downlink highlighting the Year of Education on Station, teachers from as far as the United Arab Emirates will pose their own burning questions for the astronaut and learn more about how to living—and working—is accomplished in microgravity.
