Nasa Updates

When scientists and engineers want to send commands to a spacecraft in deep space, they turn to the Deep Space Network, NASA’s international array of giant radio antennas used to communicate with spacecraft at the Moon and beyond. Operators at the Deep Space Network take commands, break them into digital bits, precisely aim these big antennas at the spacecraft, and send the commands to the spacecraft using radio waves. The antennas of NASA’s Deep Space Network are the indispensable link to robotic explorers venturing beyond Earth. They provide the crucial connection for commanding our spacecraft and receiving their never-before-seen images and scientific information on Earth, propelling our understanding of the universe, our solar system and ultimately, our place within it. Managed by NASA’s Jet Propulsion Laboratory for the Space Communications and Navigation (SCAN) Program, based at NASA Headquarters within the Space Operations Mission Directorate, the Deep Space Network is what enables missions to track, send commands to, and receive scientific data from faraway spacecraft.

On March 8, 2019, the SpaceX Crew Dragon spacecraft undocks from the International Space Station, after nearly 5 days aboard the orbiting laboratory during the company’s Demo-1 mission for NASA’s Commercial Crew Program and descends to re-enter the Earth’s atmosphere. Just over 5 hours later, the uncrewed spacecraft splashes down in the Atlantic Ocean off the coast of Florida and is recovered by SpaceX teams.

The Surface Water and Ocean Topography (SWOT) mission will measure the height of water in lakes, rivers, reservoirs, and the oceans. As climate change accelerates the water cycle, more communities around the world will be inundated with water while others won’t have enough. SWOT data will be used to improve flood forecasts and monitor drought conditions, providing essential information to water management agencies, civil engineers, universities, the U.S. Department of Defense, disaster preparedness agencies, and others who need to track water in their local areas. In this video, examples of how SWOT data will be used in these communities are shared by a National Weather Service representative in Oregon, an Alaska Department of Transportation engineer, researchers from the University of Oregon and University of North Carolina, a NASA Jet Propulsion Laboratory scientist working with the Department of Defense, and a JPL scientist working with the Louisiana Coastal Protection and Restoration Agency.
