New Status: improved Payload Ethernet Hub Gateway (iPEHG)-1 and -2 Installation: Commander (CDR) Hadfield upgraded PEHG-2 Wednesday and PEHG-1 today by removing the legacy PEHGs and installing two new iPEHGs. The new iPEHGs have enhanced configuration capabilities over the legacy PEHG, improved Gateway modes of operation and improved network protocols to support integration into Joint Station …
Our forecasters at Iowa State, and I believe via the National Weather Service, are calling this a “once in a career storm.” The heavy snow in central Iowa—really, almost on top of us right now, is the reason. We ran NPOL all night long with the D3R radar in cold rain that started around 2 […]
New Status: Burning and Suppression of Solids (BASS) Experiment (BASS): Cassidy conducted the 7th of 13 sessions planned for this experiment. BASS examines the burning and extinction characteristics of a wide variety of fuel samples in microgravity and will guide strategies for extinguishing fires in microgravity. BASS results contribute to the combustion computational models used …
We have been waiting for rain at the NPOL site. Yesterday evening it got very close- within 50 km or so. In the interim, we were waiting for convective cells to develop along what is called a radar “fine-line”. Fine-lines are little boundaries in the lowest part of the atmosphere associated with small changes in […]
A rain gauge will collect how much rain falls, but how exactly do scientists measure the size, shape, and fall speed of raindrops near the ground? Patrick Gatlin of NASA’s Marshall Space Flight Center, sent us a couple photos from Iowa of the instrument that does exactly that: a two-dimensional video disdrometer. Shaped like a […]
New Status: In-Flight Maintenance (IFM) improved Payload Ethernet Hub Gateway (iPEHG) Installation: Commander (CDR) Hadfield upgraded PEHG-2 (in LAB1D2) by removing the legacy PEHG and installing the new iPEHG. IPEGH-1 installation is scheduled for this Friday, May 3. The new iPEHG will have enhanced configuration capabilities over the existing PEHG, improved Gateway modes of operation and …
New Status: Mobile Servicing System (MSS) Operations: Today Robotics Ground Controllers powered up the Mobile Servicing System (MSS) and translated the Mobile Transporter (MT) from Worksite (WS) 4 to WS2. They then maneuvered the Space Station Remote Manipulator System (SSRMS) into position, grappled the Special Purpose Dexterous Manipulator System (SPDM), and released it from Mobile Base …
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 …
