A new study says tens of thousands of people die prematurely each year because diesel engines don’t really run as cleanly as they do in laboratory tests.
The Expedition 51 crew trained today for the next SpaceX Dragon mission due early next month. The five crew members also explored how microgravity affects their bodies to help scientists keep astronauts healthy in space. The next Dragon mission, SpaceX CRS-11, is scheduled to launch June 1 to deliver new space science gear to the …
Grasp Commissioning: To complete commissioning for the Grasp investigation hardware, Pesquet performed tasks in a seated position. Grasp is intended to provide insight into how the central nervous system integrates information from different sensory modalities encoded in different reference frames to coordinate movements of the hand with objects in the environment. Performed on the ISS, …
OsteoOmics: The crew fixated BioCells in Biocell Habitat 1 inserted the sample into the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). 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 by examining osteoblasts, which form bone, …
Two NASA astronauts switched their spacesuits to battery power this morning at 7:20 a.m., EDT aboard the International Space Station to begin a spacewalk planned to last about 2.5 hours. Expedition 51 Commander Peggy Whitson and Flight Engineer Jack Fischer will replace a critical computer relay box. The relay box, known as a multiplexer-demultiplexer (MDM), …
External (EXT) Multiplexer/Demultiplexer (MDM)-1 R&R Extravehicular Activity (EVA): With IV support from Thomas Pesquet, today Peggy Whitson (EV1) and Jack Fischer (EV2) performed a 2 hour 46 minute EVA to Remove & Replace (R&R) the EXT MDM-1 that failed on Saturday, May 20th. While Whitson performed the EXT MDM R&R, Fischer installed the Lab Nadir …
Expedition 51 Commander Peggy Whitson and Flight Engineer Jack Fischer of NASA concluded their spacewalk at 10:06 a.m. EDT. During the spacewalk, which lasted two hours and 46 minutes, the two astronauts successfully replaced a computer relay box, and installed a pair of antennas on station to enhance wireless communication for future spacewalks. Spacewalkers have …
Expedition 51 Commander Peggy Whitson and Flight Engineer Jack Fischer of NASA will venture outside the International Space Station for a 2.5-hour contingency spacewalk Tuesday, May 23. The spacewalk will begin about 8 a.m. EDT, with complete coverage on NASA Television and the agency’s website beginning at 6:30 a.m. Whitson and Fischer will replace a …
External (EXT) Multiplexer/Demultiplexer (MDM)-1 Failure: On Saturday EXT MDM-1 experienced an anomaly. Attempts to recover the MDM remotely were unsuccessful. Ground Teams configured EXT MDM-2 as primary and set up systems for the next worse failure per established Flight Rules. An IMMT was held Sunday and directed Team 4 to assess the feasibility of performing …
