NASA astronaut Tim Kopra and ESA (European Space Agency) astronaut Tim Peake completed the primary task for their spacewalk on January 15, 2016 before it was ended early by Mission Control Houston. The astronauts replaced a failed voltage regulator that caused a loss of power to one of the station’s eight power channels last November, accomplishing …
My colleagues and I spend most of our time looking for stories, images, and data related to the latest and greatest remote sensing science at NASA and beyond. This often leads us to rather technical scientific journals and obscure websites that are hardly known for their artistry. But every now and then during the course […]
Extravehicular Activity (EVA) #35: Extravehicular Activity (EVA) #35: Peake and Kopra egressed the Airlock at 7am CST in order to perform EVA #35. During the EVA, Kopra’s carbon dioxide (CO2) sensor failed and then later he noticed a water bubble in his helmet. Based on the trend, the Flight Control Team decided to terminate the …
Today's blog post is from Amanda Zangari, a member of the New Horizons' Geology, Geophysics and Imaging Team. She works at Southwest Research Institute in Boulder, Colorado. My name is Amanda Zangari, and I've been a postdoc on the New Horizons mission for 2 ½ years. It's been a wild ride, and it's amazing how …
Astronauts Tim Kopra and Tim Peake ended their spacewalk at 12:31 p.m. EST with the repressurization of the U.S. Quest airlock following an early termination of the spacewalk after Kopra reported a small water bubble had formed inside his helmet. Commander Scott Kelly will assist the crew members with an expedited removal of their spacesuits …
Approximately 2 hours into today’s spacewalk, astronauts Tim Kopra and Tim Peake have completed the replacement of a failed voltage regulator that caused a loss of power to one of the station’s eight power channels last November. The astronauts will now continue with additional tasks, including the routing of cables in advance of International Docking …
Astronauts Tim Kopra and Tim Peake switched their spacesuits to battery power at 7:48 a.m. EST, signifying the start of today’s spacewalk, planned for about six and a half hours. Kopra is wearing a spacesuit with red stripes and is designated EV1. His helmet camera displays the number 17. Peake is wearing a spacesuit with …
Fluid Shifts: Kornienko continued his Return minus 45 day (R-45) Fluid Shifts activities today in the Russian Segment with assistance from Kelly and Volkov and guidance from the ground team. He performed Optical Coherence Tomography (OCT), Cerebral and Cochlear Fluid Pressure (CCFP) and Distortion Product Otoacoustic Emissions (DPOAE) tests, and a Tonometry exam. He also …
Commander Scott Kelly and one-year crewmate Mikhail Kornienko continue their contribution to the fluid shifts study with the aid of Russian cosmonaut Sergey Volkov. Data from this long-term study hopes to reveal correlations between the distribution of fluid in the body and changes in vision during prolonged stays in microgravity. Final preparations are underway for …
