Using the instrument, which can detect ammonia’s chemical signature by the infrared light it absorbs, the authors found elevated levels of the gas near several sources, including agricultural fields, livestock…
Scientists knew from previous Cassini data-mining that nitrogen- and oxygen-bearing organic compounds were present in particles from Saturn’s E ring, a faint, wide outer band around the planet fed by…
The IUVS data also offers an estimated upper limit of the comet’s ratio of deuterium (a heavy isotope of hydrogen) to regular hydrogen, a tracer of the comet’s origin and…
The two satellites make up the Copernicus Sentinel-6/Jason-CS (Continuity of Service) mission, the latest in a series of ocean-observing radar altimetry missions that have monitored Earth’s changing seas since the…
Launch timelineMeasuring 19.1 feet (5.82 meters) long and 7.74 feet (2.36 meters) high (including the communications antennas), the satellite weighs in at around 2,600 pounds (1,200 kilograms) when loaded with…
The Sentinel-6B mission continues a decades-long effort to monitor global sea level and ocean conditions using precise radar measurements from space. Since the early 1990s, satellites launched by NASA and…
2. Data from the Copernicus Sentinel-6/Jason-CS mission helps NASA prepare for the next phase of space exploration.The better we understand Earth, the better NASA can carry out its mission to…
In order to best position JPL going forward, we are taking steps to restructure and establish an appropriate size to ensure future success. As part of this effort, JPL is…
The images demonstrate how the L-band SAR can discern what type of land cover — low-lying vegetation, trees, and human structures — is present in each area. This capability is…
The difference longer wavelengths of light make, even within the infrared spectrum, are stark when comparing the images from Webb’s MIRI and NIRCam (Near-Infrared Camera) instruments. Glowing gas and dust…
