As the DC-8 flies around the world for the ATom project, we are crossing many time zones and occasionally loosing and gaining days! For most of the first half of the project, I didn’t really notice these time changes. I gained the most time leaving Boston for California and had one to two hourly stretches […]
By Eric Lindstrom One of the most common questions I get (and the first comment to this blog) is “How do you measure ocean salinity from space?” During the SPURS-1 campaign in 2012 I wrote a blog post on this topic. Basically the story is one of building a very sensitive instrument (a radiometer) to […]
Two NASA astronauts switched their spacesuits to battery power this morning at 8:04 a.m. EDT aboard the International Space Station to begin a spacewalk planned to last some six and a half hours. Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins will install the first of two international docking adapters (IDAs) that will …
Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins of NASA will begin a spacewalk outside of the International Space Station at 8:05 a.m. EDT Friday. NASA TV coverage will begin at 6:30 a.m. NASA TV’s Public Channel (NTV-1) will broadcast enhanced coverage of the spacewalk including operational commentary, in-studio experts and features. The …
Mouse Epigenetics Cage Unit Maintenance: The crew completed standard maintenance activities for the Mouse Epigenetics experiment by refilling the Transportation Cage Units with water and checking the water nozzles of the individual cages. The Mouse Epigenetics investigation studies altered gene expression patterns in the organs of male mice that spend one month in space, and …
A new port for commercial crew vehicles was robotically removed from the back of the SpaceX Dragon Wednesday night. The International Docking Adapter was placed in position for its installation Friday morning to a pressurized mating adapter attached to the Harmony module. VIDEO: International Docking Adapter is Extracted from SpaceX Dragon Two spacewalkers, Commander Jeff …
Fluid Shifts Operations In the Service Module: With ground team assistance, crewmembers performed Fluid Shifts Imaging exams by configuring the Optical Coherence Tomography (OCT) and the Distortion Product Otoacoustic Emission (DPOAE) hardware, before completing a DPOAE test, OCT exam, and a Tonometry exam. The purpose of this investigation is to characterize the space flight-induced fluid …
On August 13, 2016, we published an image and video showing meteors streaking across the night sky. The perspective is a new one. Instead of looking up from the ground, the camera recorded the action from the vantage point of the International Space Station (ISS). In case you missed it, you can see the image and read […]
By Eric Lindstrom Fieldwork in physical oceanography, like many sciences, requires enormous preparation followed by a shorter very intensive period of action. SPURS-2 is no exception. The work over the next six weeks has been in the planning and staging for several years. Now, all the gear and scientists have reached the ship and we […]
This year we teamed up with the Cold Regions Research and Engineering Lab (CRREL) (thank you Dave Finnegan and Adam Lewinter for the collaboration to produce repeat LiDAR surveys of our Rio Behar catchment primary study areas). LiDAR stands for Light Detection and Ranging (or, depending on where you are in the world, Laser RADAR), […]
