Maybe you have heard people call Earth “the water planet.” The nickname is well-deserved. As this mosaic of images from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite conveys so well, the majority of Earth’s surface is covered by either liquid or frozen water.
TripleLux-B (BIOLAB): Gerst unstowed tools and items needed for the installation of the distribution and cleaning (D&C) cassette of the Biolab Microscope. This activity was performed in preparation of the upcoming TripleLux-B experiment. The objective of Triplelux-B is to further understand the cellular mechanisms underlying the increase in radiation responses, and the impairment of the …
NASA astronaut Barry Wilmore worked throughout Tuesday inside Japan’s Kibo laboratory to remove a Cubesat deployer from the laboratory’s airlock. The deployer experienced problems in August, when some of the mini satellites did not deploy as expected and later deployed spontaneously. Wilmore’s Expedition 41/42 crewmates Elena Serova and Alexander Samokutyaev worked throughout the day on …
There was a daylight fireball seen from Arkansas to Alabama this morning at about 9:38 CST. If you saw the meteor and have information on its directionality, where you saw it from, etc., please comment below. Also, it would be helpful if you filled out an eyewitness report on amsmeteors.org.
Russian Joint Research (RJR) Surface Sampling: Serova performed air sampling in USOS Segment Modules (Columbus, Japanese Pressurized Module (JPM), Lab, Node 1, 2, and 3). The investigation refines locations and surfaces prone to microbial contamination throughout the ISS, share monitoring technologies and data between NASA and Roscosmos, and provides a scientific basis for decisions about …
Expedition 41 Commander Max Suraev and Flight Engineers Reid Wiseman and Alexander Gerst are in their final week aboard the International Space Station. All three homebound crew members spent time on Monday preparing for their departure. Expedition 41 will end Nov. 9 when it undocks inside the Soyuz TMA-13M spacecraft at 7:29 p.m. EST. Gerst …
At the southern tip of Chile, the city of Punta Arenas is in a prime location for accessing Antarctica. This is one of the reasons IceBridge calls Punta Arenas home for several weeks during Antarctic field campaigns. But IceBridge isn’t the only scientific game in town. The U.S. Antarctic Program (USAP), British Antarctic Survey (BAS) and […]
Circadian Rhythms: Gerst donned instrumentation to begin the 36 hour Circadian Rhythm experiment which investigates the role of synchronized circadian rhythms, or the “biological clock,” and how it changes during long-duration spaceflight. Researchers hypothesize that a non-24-hour cycle of light and dark affects crewmembers’ circadian clocks. The investigation also addresses the effects of reduced physical …
The Expedition 41 trio of Reid Wiseman, Alexander Gerst and Max Suraev are returning home November 9. They checked their Sokol suits, which are worn during a Soyuz launch and entry, for leaks and started preparing for their departure. NASA astronaut Barry Wilmore, who will be in space until March, worked on the Zebrafish Muscle …
