Analog-1: As part of the preparation for the Analong-1 investigation, which arrives later, the crew performed a software load on the appropriate computer. Space is such a harsh place for humans and machines that future exploration of the Solar System may involve sending robotic explorers to “test the waters” on uncharted planets before sending humans. …
By Katie Orndahl /YUKON AND NORTHWEST TERRITORIES, CANADA/ I spent my summer searching for arctic spirits: barren-ground caribou who are, somehow, both omnipresent and elusive. My journey, it turns out, would trace the migration route of the Porcupine caribou herd, linking boreal forest and arctic tundra ecosystems unlike any other northern mammal. The wild landscape …
Science experiments continue aboard the International Space Station as two NASA astronauts prepare for their first spacewalk together, which is set to take place Friday. The Expedition 61 crew researched a variety of space phenomena today and reviewed procedures for tomorrow’s excursion. Flight Engineers Christina Koch and Jessica Meir will venture out into the vacuum …
US Extravehicular Activity (EVA) Battery Charging Discharging Unit (BCDU) 2B2 Replacement Preparations: Over the past weekend when activating the new Li-Ion 2B2 battery BCDU, the converter close command failed; ground teams have determined that performing an EVA to replace the failed BCDU with a new spare will restore full functionality to the Channel 2B. Today, …

The Expedition 61 crew is adjusting its schedule this week to accommodate the new spacewalk plans at the International Space Station. Astronauts Christina Koch and Jessica Meir are continuing their preparations …
US Extravehicular Activity (EVA) Battery Charging Discharging Unit (BCDU) 2B2 Replacement Preparations: During periods of insolation, the BCDU extracts power from the primary power bus, conditions this power and charges the batteries. During periods of eclipse, the BCDU extracts power from the battery bus, conditions this power and supplies it to the primary power bus …
NASA has set the first all-female spacewalk for later this week while the Expedition 61 crew works life science today aboard the International Space Station. A new commercial cargo vehicle is also being readied for future delivery missions. NASA astronauts Christina Koch and Jessica Meir are readying their spacesuits and reviewing procedures for a spacewalk …
