The weather forecast continues to look good for launch this morning from Vandenberg Air Force Base. Skies are partly to mostly cloudy, there's nothing significant on the radar, and winds are light at 9 to 10 knots. There are no watches or warnings in effect, and weather is "green" on all constraints, according to 1st …
SMAP will produce accurate, high-resolution results through the combined efforts of its two instruments, a radar and a radiometer. The radar emits a signal, then measures the backscatter that bounces back from Earth. The radiometer, on the other hand, simply records the microwave signal our planet naturally emits. "Active Passive" in the mission's name refers …
Think for a moment about the soil beneath your feet or outside your window. It is damp, dry, or frozen? Maybe it's flood-prone, or dry to the point of cracking. Locally and globally, soil moisture matters. Water in Earth's soil represents only a small percentage of our planet's total quantity of water. But food crops …

The Expedition 42 crew worked Wednesday with fruit flies, a humanoid robot and a Dragon spacecraft. Also, Europe’s Automated Transfer Vehicle-5 fired its engines for nearly five minutes, slightly lowering the station’s orbit to prepare for an upcoming ISS Progress 58 resupply mission. Commander Barry Wilmore and Italian astronaut Samantha Cristoforetti packed gear inside the …
Sally RideEarth Knowledge Acquired by Middle School Students (Sally Ride EarthKAM): Samokutyaev installed the 180 mm lens on the EarthKam and continued with the week long imaging session. Not everyone can go to space, but everyone can see Earth from an astronaut’s perspective with the Sally Ride EarthKAM program. Thousands of students can remotely control …
Managers from NASA and United Launch Alliance (ULA) met Tuesday at Vandenberg Air Force Base in California to assess the status of NASA's Soil Moisture Active Passive (SMAP) spacecraft and the ULA Delta II rocket that will boost SMAP into space. At the conclusion of the Launch Vehicle Readiness Review, a poll was taken and …
NASA's Soil Moisture Active Passive (SMAP) spacecraft will be boosted into orbit aboard a United Launch Alliance Delta II rocket from Vandenberg Air Force Base in California. Learn how SMAP and the Delta II were readied for liftoff.
