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 […]
New Status: ENERGY Experiment: Hadfield completed Day 4 of his 10-day ENERGY experiment session. The experiment includes eating a standardized meal, diet logging, specific water intake, measurements of Oxygen uptake, collection of urine samples, and wearing an armband activity monitor. A loss in astronauts’ body mass is a systematic observation during space flight. The aim of …
New Status: High Rate Communications System (HRCS) Ku Comm Unit 1 Installation: Commander (CDR) Hadfield and Flight Engineer (FE)-6 Marshburn removed the legacy High Rate Frame Multiplexer (HRFM) and Audio Interface Unit (AIU) scar bracket and installed the Ku Comm Unit 1 into Avionics Rack #3 (LAB1D2). Following Ku Comm Unit 1 installation, the ground performed …
By Lora Koenig April 9, 2013 — I suppose you could say I got up at 3:38 am this morning, but I don’t think I ever really went to sleep. I did get into my sleeping bag around 10 pm last night, but I didn’t sleep. Yesterday we had 20-knot katabatic winds, cold air flowing […]
