OsteoOmics: The crew changed BioCell media in BioCell Habitat 4. The media in all four of the habitats are changed in this second of four weeks of OsteoOmics operations. Crewmembers experience bone loss in orbit, stemming from the lack of gravity acting on their bones. OsteoOmics investigates the molecular mechanisms that dictate this bone loss …
Intense heat and fire will fill the north side of the flame trench beneath the pad when NASA’s Space Launch System (SLS) rocket and Orion spacecraft lift off from Launch Complex 39B at NASA’s Kennedy Space Center in Florida. A project to upgrade the walls of the flame trench to withstand these conditions recently was …
Commander Peggy Whitson will work outside the space station for the ninth time in her career on Friday. She will be joined by Flight Engineer Jack Fischer who will embark on his first spacewalk. The duo will exit the Quest airlock around 8 a.m. EDT for about 6.5 hours of external tasks. They will replace …

The Expedition 51 crew reviewed Friday’s spacewalk today and researched how the human body adapts to microgravity. At the Johnson Space Center, three future International Space Station crew members introduced themselves live on NASA TV. Astronauts Peggy Whitson and Jack Fischer reviewed procedures for Friday morning’s spacewalk this morning. The duo will replace an avionics …
OsteoOmics: The crew changed BioCell media in BioCell Habitat 2. The media in the other four habitats will be changed this week. This is the second of four weeks of OsteoOmics operations. Crewmembers experience bone loss in orbit, stemming from the lack of gravity acting on their bones. OsteoOmics investigates the molecular mechanisms that dictate …
We created some interesting patterns reminiscent of alien crop circles during our snow surveys in Alaska’s Wrangell St Elias National Park last month. Anne Nolin, Chris Cosgrove, Kelly Sivy and I were flown to the Jaeger Mesa cabin in an R44 helicopter, and from there we spent a week measuring snow depth and density along […]
The Expedition 51 crew is getting ready for a spacewalk Friday and working on several scientific investigations. Robotics controllers also swapped out a power relay box over the weekend through a complex and innovative robotic procedure. Astronauts Peggy Whitson and Jack Fischer will exit the International Space Station for a 6.5-hour spacewalk on Friday. The …
Main Bus Switching Unit (MBSU) 2 Remove & Replace (R&R): Friday evening and into Saturday, Robotics Ground Controllers maneuvered the Special Purpose Dexterous Manipulator (SPDM) Arms and successfully removed the failed MBSU 2 and replaced it with a spare. The failed MBSU was then installed onto External Stowage Platform (ESP)-2. After a successful power up …
Your challenge is to use the comments section to tell us what we are looking at, when the image was acquired, and why the scene is interesting.
