The Surface Water and Ocean Topography (SWOT) mission is a satellite altimeter jointly developed and operated by NASA and CNES, the French space agency, in partnership with the Canadian Space Agency (CSA) and UK Space Agency (UKSA). The objectives of the mission are to make the first global survey of the Earth’s surface water, to observe the fine details of the ocean surface topography, and to measure how terrestrial surface water bodies change over time.

While past satellite missions like the Jason series altimeters (TOPEX/Poseidon, Jason-1, Jason-2, Jason-3) have provided variation in river and lake water surface elevations at select locations, SWOT will provide the first truly global observations of changing water levels, stream slopes, and inundation extents in rivers, lakes, and floodplains. In the world’s oceans, SWOT will observe ocean circulation at unprecedented scales of 15–25 km (9.3–15.5 mi), approximately an order of magnitude finer than current satellites. Because it uses wide-swath altimetry technology, SWOT will almost completely observe the world’s oceans and freshwater bodies with repeated high-resolution elevation measurements, allowing observations of variations.

The inflatable antenna technology concept was originally called the Large Balloon Reflector (LBR) concept when it was picked up by the NASA Innovative Advanced Concepts (NIAC) program in 2013. It may have sounded like a wild idea to some at first, but because NASA gave it a chance this technology could revolutionize high-speed communications. NASA 360 takes a look at a NASA Innovative Advanced Concept (NIAC) that launched a business, became a space mission, and could change the way we communicate on Earth.

The National Oceanic and Atmospheric Administration’s (NOAA) Geostationary Operational Environmental Satellite-T (GOES-T) satellite spacecraft lifts off from Canaveral Space Force Station’s Space Launch Complex 41 at 4:38 p.m. EST, March 1, 2022, on a joint effort with NASA to help meteorologists observe and predict local weather events.

Hurricanes are some of the most powerful and destructive weather events on Earth. To help study these powerful storms, NASA is launching TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats), a collection of six small satellites designed to measure storm strength by detecting the thermal radiation naturally emitted by the oxygen and water vapor in the air.

In June 2021, NASA launched a test version of the satellite, called a pathfinder, ahead of the constellation of six weather satellites planned for launch in 2022. When launched, the TROPICS satellites will work together to provide near-hourly microwave observations of a storm’s precipitation, temperature, and humidity. The mission is expected to help scientists understand the factors driving tropical cyclone intensification and to improve forecasting models.

Hundreds of meltwater lakes hide deep beneath the expanse of Antarctica’s ice sheet. With a powerful laser altimeter system in space, NASA’s Ice Cloud and land Elevation Satellite-2 (ICESat-2) is helping scientists “see” under the ice.

Globally, 2020 was the hottest year on record, effectively tying 2016, the previous record. Overall, Earth’s average temperature has risen more than 2 degrees Fahrenheit since the 1880s. Temperatures are increasing due to human activities, specifically emissions of greenhouse gases, like carbon dioxide and methane.
