Scientist, engineer, test subject and tradesperson—astronauts in orbit wear many different hats. In this 360° timelapse, ESA astronaut Matthias Maurer works to repair a faulty valve behind EXPRESS-Rack 3.
Water On-Off Valve 8 (WOOV-8), along with WOOV-6 and WOOV-7, determines whether the cooling water of Europe's Columbus module flows through, or bypasses, the heat exchange system that transfers waste heat to downstream cooling circuits outside the International Space Station. The valve has been a problem child for ground teams and astronauts for the past few years and was first replaced during a complicated operation in 2013.
It was last replaced by ESA astronaut Thomas Pesquet in October 2021, but continued issues led Matthias to try out a reserve valve to see if an unplanned conversion was possible. The operation was successfully completed on the real WOOV-8 in December 2021, and all involved breathed a sigh of relief.
Performing maintenance and repair tasks in weightlessness is especially difficult as astronauts have the added challenge of trying to hold themselves in position while turning a screw or securing a hatch.

In our weekend drive we aimed to get up close to the "Toron" block, which is a "float rock" or out of place chunk of bedrock in the workspace. Unlike many float rocks, Toron's original location (tantalizingly out of reach on "The Prow,") can be pinpointed with confidence, which allows us to analyze the upper reaches of The Prow from a safe position.

Animal diversity is fascinating, but how is this reflected in their genetic material, the genome? Is it possible to definitely distinguish animals from one another based on genetic information, and perhaps even make predictions about how genetic information changes over time? This has been the great hope since the beginning of the "genome era" in 2000, when the human genome was sequenced for the Ancient ice reveals mysterious solar storm

Through analyzes of ice cores from Greenland and Antarctica, a research team led by Lund University in Sweden has found evidence of an extreme solar storm that occurred about 9,200 years ago. What puzzles the researchers is that the storm took place during one of the sun's more quiet phases - during which it is generally believed our planet is less exposed to such events.

January 25, 2022 - New research provides further evidence that rocks representing up to a billion years of geological time were carved away by ancient glaciers during the planet's "Snowball Earth" period, according to a study published in Proceedings of the National Academy of Sciences.

The planned launch of an Astra Space rocket from Florida was scrubbed Saturday after the failure of ground equipment needed to launch.
"Unfortunately, due to a range asset that has gone out of service today, we are going to stand down from today's launch attempt of the ELaNa 41 Mission," said Carolina Grossman, director of product management at the company, during the live broadcast.
