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), […]

Flight controllers and the Expedition 48 crew are preparing for tonight’s International Docking Adapter extraction work and Friday morning’s installation spacewalk. The orbital residents are also continuing to load the SpaceX Dragon with gear and science for return to Earth. Controllers on the ground checked the Canadian robotics systems they will use to remove the …

Hi there, After a science-packed 3 weeks on the ice sheet, the team has returned to Kulusuk, more successful than we ever expected. We accomplished the following: Drilled ice cores at three sites to measure firn density, and to take chemistry samples Installed wells at three sites for water sampling Measured firn permeability at different […]

Fluid Shifts Imaging with Chibis in the Service Module (SM): With ground team assistance, crewmembers continued the final week of this set of Fluid Shifts operations by configuring the Ultrasound 2 hardware prior to performing ultrasound scans in the SM while using the Chibis. The Fluids Shift investigation is divided into three segments: Dilution Measures, …

Space station and Commercial Crew managers wrapped up a spacewalk briefing Monday afternoon discussing the installation of a new International Docking Adapter at the end of the week. Spacewalkers Jeff Williams and Kate Rubins will begin the installation work Friday at 8:05 a.m. EDT to enable future crew vehicles from Boeing and SpaceX to dock …

On the next part of our journey the DC-8 traversed the tropical Pacific Ocean. I have always been deeply fascinated by this part of the atmosphere. The tropical Pacific Ocean lies over very warm water heated by the sun, and it is often considered to be the “firebox” of the atmosphere, the place where vast […]
