NASA's SMAP (Soil Moisture Active Passive) satellite observatory conducted a field experiment as part of its soil moisture data product validation program in southern Arizona on Aug. 2-18, 2015. The images here represent the distribution of soil moisture over the SMAPVEX15 (SMAP Validation Experiment 2015) experiment domain, as measured by the Passive Active L-band System (PALS) developed by NASA's Jet Propulsion Laboratory, Pasadena, California, which was installed onboard a DC-3 aircraft operated by Airborne Imaging, Inc. Blue and green colors denote wet conditions and dry conditions are marked by red and orange. The black lines show the nominal flight path of PALS. The measurements show that on the first day, the domain surface was wet overall, but had mostly dried down by the second measurement day. On the third day, there was a mix of soil wetness. The heterogeneous soil moisture distribution over the domain is typical for the area during the North American Monsoon season and provides excellent conditions for SMAP soil moisture product validation and algorithm enhancement. The images are based on brightness temperature measured by the PALS instrument gridded on a grid with 0.6-mile (1-kilometer) pixel size. They do not yet compensate for surface characteristics, such as vegetation and topography. That work is currently in progress. http://photojournal.jpl.nasa.gov/catalog/PIA19879

Boeing’s CST-100 Starliner’s airbags inflate in preparation for landing in the New Mexico desert in the company’s Pad Abort Test for NASA’s Commercial Crew Program.

Boeing’s CST-100 Starliner’s four launch abort engines and several orbital maneuvering and attitude control thrusters ignite in the company’s Pad Abort Test, pushing the spacecraft away from the test stand with a combined 160,000 pounds of thrust, from Launch Complex 32 on White Sands Missile Range in New Mexico. The test, conducted Nov. 4, 2019, was designed to verify that each of Starliner’s systems will function not only separately, but in concert, to protect astronauts by carrying them safely away from the launch pad in the unlikely event of an emergency prior to liftoff.
