Walt Petersen is the Ground Validation Scientist for the Global Precipitation Measurement (GPM) mission, based at NASA’s Wallops Flight Facility in Virginia. He manages all of GPM’s ground validation operations, the field campaigns that ensure that satellites measure rainfall and precipitation from space accurately. From May 1 to June 15, he is leading the Iowa […]
New Status: 51 Progress (P) Reboost – Yesterday the International Space Station (ISS) performed a nominal 1.53 meters per second reboost using 51P thrusters. This reboost provided phasing for the upcoming 33 Soyuz landing and 35 Soyuz launch. Nutrition and Pro-K Experiment Sample Collections: Cassidy collected blood and urine samples and stowed them in the Minus Eighty …
Thanks to everybody who offered answers to our five puzzlers last week. Congratulations to Christina Stiefel for solving Puzzler #5, Alan Wessman for solving Puzzler #3, and Angie Connelly for solving Puzzler #2! Honorable mention to Marcus Scherer for nearly solving Puzzler #1. Puzzler #1 showed undisturbed rainforest canopy in Brazil in part of Pará […]
51 Progress (51P) Docking: 51P successfully docked to the ISS Russian Segment Service Module (SM) aft port with this morning with contact and capture occurring at 7:26 am CDT. All Progress systems operated nominally with the exception of Kurs АСФ2 antenna which had still not deployed. A software patch was uplinked to the 51P vehicle which …
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 fifth image is above. Your challenge is to use the comments section to tell us what part […]
New Status: 51 Progress (51P) Docking Status: Following yesterday’s launch, the Progress 51P Kurs-A antenna АСФ2 failed to deploy nominally. All attempts by MCC-M to deploy the antenna have been unsuccessful. MCC-M is working a plan to dock Progress to the SM AFT docking port with the antenna in the stowed configuration, which will be reviewed …

By Clément Miège Hi there! Today I have another story to share with you! It’s about the tracking of the temperature evolution of the firn aquifer temperature by using two thermistor strings that we set up in the two holes made by Jay (see Jay’s post on drilling for details). By tracking temperatures over a […]
New Status: 51 Progress (51P) Launch: 51P launched at 5:12 am CDT. Ascent was nominal and the vehicle reached orbital insertion at 5:21 am CDT. All appendages except Kurs-A antenna АСФ2 were deployed. Telemetry shows the АСФ2 antenna remains in its fully stowed position. The Russians are troubleshooting in the hopes of deploying the antenna. A …
