SpaceX Crew Dragon Returns from Space Station on Demo-1 Mission
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 Simplified High Impact Energy Landing Device (SHIELD) is a lander concept being tested at NASA's Jet Propulsion Laboratory (JPL). It could one day provide a new way for low-cost missions to land on Mars.
Rather than rely on parachutes or retrorockets, SHIELD would include a collapsible, accordion-like base to absorb the energy of a landing. A full-size prototype of the base was tested on Aug. 12, 2022. The prototype was hurled at the ground from the top of a nearly 90-foot-tall (27-meter-tall) drop tower at JPL. A steel plate ensured the impact was even harder than what would be experienced on Mars.
The design worked: After crushing against the steel plate at 110 mph (177 kph), several electronic components inside the SHIELD prototype, including a smartphone, survived the impact.

SWOT: Earth Science Satellite Will Help Communities Plan for a Better Future
A new Earth science mission, led by NASA and the French space agency Centre National d'Études Spatiales (CNES), will help communities plan for a better future by surveying the planet's salt and freshwater bodies. 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.

SWOT is expected to launch from Vandenberg Space Force Base in California in December 2022.
The mission is a collaboration between NASA and CNES, with contributions from the Canadian Space Agency and UK Space Agency. JPL, which is managed for NASA by Caltech in Pasadena, California, leads the U.S. component of the project.
