6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Located off the coast of Ecuador, Paramount seamount is among the kinds of ocean floor features that certain ocean-observing satellites like SWOT can detect by how their gravitational pull affects the sea surface. NOAA Okeanos Explorer Program More accurate maps based on data from the SWOT mission can improve underwater navigation and result in greater knowledge of how heat and life move around the world’s ocean. There are better maps of the Moon’s surface than of the bottom of…

Alien life could survive on Earth-like planets circling dead stars, study suggests

NeRD

White dwarfs may be stellar corpses, but that doesn’t mean that everything around them has to be lifeless. That’s the conclusion of Florida Institute of Technology researcher Caldon Whyte, who’s particularly fascinated by these stellar remnants. Until now, scientists have generally thought that planets orbiting white dwarfs would be unsuitable for life because the dynamic temperature decrease of their dead parent star makes their atmospheres too unstable. As the James Webb Space Telescope (JWST) increasingly investigates white dwarf systems, however, Whyte and colleagues developed a model capable of assessing if…

New Bridge Ready to Serve NASA, America’s Space Interests

NeRD

The high-rise bridge that serves as the primary access point for employees and visitors to NASA’s Kennedy Space Center in Florida is fully operational. In the late hours of March 18, 2025, the Florida Department of Transportation (FDOT) opened the westbound portion of the NASA Causeway Bridge, which spans the Indian River Lagoon and connects NASA Kennedy and Cape Canaveral Space Force Station to the mainland. This new bridge span (right side of photo) sits alongside its twin on the eastbound side, which has accommodated traffic in both directions since…

SpaceX launches 23 Starlink internet satellites to orbit from Florida’s Space Coast (video, photos)

NeRD

SpaceX launched yet another batch of its Starlink internet satellites to orbit from Florida this afternoon (March 18). A Falcon 9 rocket carrying 23 Starlink craft, including 13 with direct-to-cell capability, lifted off from Cape Canaveral Space Force Station today at 3:57 p.m. EDT (1957 GMT). About eight minutes later, the rocket’s first stage touched down on the SpaceX drone ship “A Shortfall of Gravitas,” which was stationed in the Atlantic Ocean. It was the 19th launch and landing for this particular booster, according to a company mission description. A…

Never-‘stuck’ Starliner astronauts return to Earth at last with Crew-9 duo in SpaceX Dragon splashdown

NeRD

The first astronauts to fly on board two different commercial spacecraft during a single mission have returned to Earth, splashing down with two of their International Space Station crewmates. Sunita “Suni” Williams and Barry “Butch” Wilmore did not set out to make history other than being the first crew to launch on Boeing’s CST-100 Starliner capsule. After their capsule encountered propulsion issues, though, and NASA, out of an abundance of caution, decided to land it without them on board, Williams and Wilmore were reassigned to SpaceX‘s Crew Dragon to complete…

Watch the sun set over the moon in epic video from private Blue Ghost lunar lander

NeRD

Firefly Aerospace’s Blue Ghost lunar lander made the most of its last few hours of life on the moon. The solar-powered Blue Ghost shut down on Sunday evening (March 16), shortly after the sun set over its lunar locale. The lander watched our star’s descent and disappearance over the cratered horizon, capturing the oncoming, killing darkness in a poignant video that Firefly shared with the world today (March 18). “These are the first high-definition images taken of the sun going down and then going into darkness at the horizon [on…
