Each month, Earth Observatory offers up a puzzling satellite image here on Earth Matters. In celebration of Earth Month 2013, we’re upping the ante. We are going to release a new puzzler image every day this week. The first image is above. Your challenge is to use the comments section to tell us what part […]

Suomi NPP is the result of a partnership between NASA, NOAA, and the Department of Defense.
New Status: Russian Segment (RS) Extravehicular Activity (EVA) #32: Flight Engineer (FE)-1 Vinogradov and FE-4 Romanenko performed a 6 hour 38 minute EVA. Egress was at 9:03 am. All planned tasks were completed nominally, including installation of the Obstanovka experiment, and the removal and replacement of the Laser Radar Reflector (LRR). The LRR is used as …
New Status: Ku-Comm Unit #1 High-Rate Communications System (HRCS) COAX Connections: Commander (CDR) Hadfield and Flight Engineer (FE)-6 Marshburn connected Ku Comm Unit 1 to the Space to Ground Transmitter Receiver Controller (SGTRC) final configuration. The Ground activated Ku-Comm Unit 1 and confirmed video, payload data and Orbiter Communication Adapter (OCA) were functioning nominally. This completes …
By Ludovic Brucker We were on Greenland’s ice sheet for only a week, but despite the short deployment, we had to accomplish two main science objectives. The first was drilling two deep cores into the firn (aged snow) and ice (30- and 65-m deep, respectively), to insert temperature probes that will record temperature evolution at […]
New Status: Blood Pressure (BP) Regulation (Reg) Experiment: Hadfield set up the Human Research Facility (HRF) PFS (Pulmonary Function System) and the European Physiology Module (EPM) Cardiolab (CDL) Leg/Arm Cuff System (LACS) and conducted the first ever session of this experiment. Marshburn is scheduled to conduct the experiment Friday. The test will help to identify the …
New Status: Mobile Servicing System (MSS) Operations: Last night Robotics Ground Controllers powered up MSS and maneuvered the Space Station Remote Manipulator System (SSRMS) into position to support a video survey of Pressurized Mating Adapter (PMA)2. They used the SSRMS Tip Elbow Camera Light Pan/Tilt Assembly (CLPA) to perform the survey then maneuvered the SSRMS back …
By Clément Miège Hi there! Today I will give you some background on the radar measurements we collected in southeast Greenland. The radar we deployed is sensitive to snow density changes and to wet snow. The main goal of the radar measurements was to provide information about the spatial variations of the top of the […]
New Status: 49 Progress (49P) Undock: 49P undocked nominally from the ISS Service Module (SM) aft port at 7:02 am CDT. 49P performed a nominal 15-sec (∆V ≈ 0.67 m/s) automated separation burn at 7:05 am CDT, followed by a nominal 10.695 m/s retrograde phasing burn at 10:15 am CDT. 49P will perform free flight burns …
By Jay Kyne (Greenland Aquifer Team’s driller) At first we all talked on the phone about it. And then I saw the picture: another driller had drilled into water and, as the drill hung on the surface, there was water dripping from it. Of course that drill quickly froze. So the question was: how do […]
