How Do Spacecraft Slow Down? We Asked a NASA Technologist
How do spacecraft slow down? Rigid heat shields and retropropulsion have been the favorites of engineers for years. Now NASA is testing a new inflatable heat shield technology that could allow us to carry even larger payloads to worlds with atmospheres: https://www.nasa.gov/loftid
Launching on Nov. 1 aboard a United Launch Alliance Atlas V rocket along with NOAA’s JPSS-2 mission, the Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID, will demonstrate the heat shield’s ability to slow down and survive atmospheric entry: https://go.nasa.gov/3N7yzBG

NASA Tests Ways to Crash Land on Mars
We’re testing a new way of landing on Mars… by crashing into its surface.
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.

2:05 - Protecting Infrastructure - Alaska
2:54 - National Security - Department of Defense
3:24 - Coastal Protection - Mississippi River Delta
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.

Chasing Sprites in Electric Skies
Paul Smith is a night-sky fanatic and photographer. His obsession is sprites: immense jolts of light that flicker high above thunderstorms. Last October, he guided NASA scientist Dr. Burcu Kosar through the backroads of Oklahoma to catch one herself. Although she’d studied sprites for more than 15 years, she hadn’t yet chased one.

133 Days on the Sun | NASA Video
This video chronicles solar activity from Aug. 12 to Dec. 22, 2022, as captured by NASA’s Solar Dynamics Observatory (SDO). From its orbit in space around Earth, SDO has steadily imaged the Sun in 4K x 4K resolution for nearly 13 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system.
With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 133-day time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme-ultraviolet wavelength that shows the Sun’s outermost atmospheric layer: the corona. Compiling images taken 108 seconds apart, the movie condenses 133 days, or about four months, of solar observations into 59 minutes. The video shows bright active regions passing across the face of the Sun as it rotates. The Sun rotates approximately once every 27 days. The loops extending above the bright regions are magnetic fields that have trapped hot, glowing plasma. These bright regions are also the source of solar flares, which appear as bright flashes as magnetic fields snap together in a process called magnetic reconnection.
While SDO has kept an unblinking eye pointed toward the Sun, there have been a few moments it missed. Some of the dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. Other blackouts are caused by instrumentation being down or data errors. SDO transmits 1.4 terabytes of data to the ground every day. The images where the Sun is off-center were observed when SDO was calibrating its instruments.
SDO and other NASA missions will continue to watch our Sun in the years to come, providing further insights about our place in space and information to keep our astronauts and assets safe.
The music is a continuous mix from Lars Leonhard’s “Geometric Shapes” album, courtesy of the artist.

NASA's Psyche Mission to an Asteroid: Official NASA Trailer
Join the journey as NASA’s Psyche mission team prepares for a targeted Oct. 5, 2023, launch to explore a unique metallic asteroid orbiting the sun between Mars and Jupiter. The asteroid, likely made largely of nickel-iron metal mixed with rock, could contain metal from the core of a planetesimal (the building block of an early rocky planet) and may offer a unique window into the violent history of collisions and accretion that created the terrestrial planets like Earth. Arizona State University leads the Psyche mission.
JPL, which is managed by Caltech for NASA, is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar Technologies in Palo Alto, California, provided the high-power solar electric propulsion spacecraft chassis.
