This new spaceflight tech has a very retro feel. The world’s first wooden satellite, a tiny Japanese spacecraft called LignoSat, arrived at the International Space Station (ISS) today (Nov. 5) aboard a SpaceX Dragon cargo capsule. LignoSat measures just 4 inches (10 centimeters) on each side, but it could end up having a big impact on spaceflight and exploration down the road. “While some of you might think that wood in space seems a little counterintuitive, researchers hope this investigation demonstrates that a wooden satellite can be more sustainable and…

Over 100 astronomers from leading U.S. universities have signed an open letter calling for an assessment of potential impacts of satellite megaconstellations on Earth’s environment. The researchers urge the U.S. Federal Communications Commission (FCC), which approves satellite deployments in the U.S., to halt megaconstellation launches and conduct a thorough assessment of their possible environmental impacts before awarding further licenses. U.S. government agencies are bound by the National Environmental Protection Act (NEPA), which requires them to consider the environmental impacts of their decisions. A 1986 categorical exclusion, however, means that satellites…

Japanese space-sustainability company Astroscale just inked a $90 million deal to take a bus-sized rocket stage out of orbit by the end of the decade. The pioneering project, funded by the Japanese Aerospace Exploration Agency (JAXA), is a continuation of Astroscale’s ADRAS-J mission, which recently completed an up-close orbital inspection of a 12-year-old upper stage of a Japanese H-2A rocket. The new mission, called ADRAS-J2, will grab the 3-ton, 36-foot-long (11 meters) rocket stage using a robotic arm and pull it into Earth’s atmosphere to burn up, demonstrating a critical…

Scientists are trying to build a new sort of satellite, and have recently tested their idea with the Starling Formation-Flying Optical Experiment, or “StarFOX.” You may be getting flashbacks to the retro Star Fox video game series — and you’d be right to imagine this experiment as a science fiction fantasy brought into reality. There are no space-faring animals here, though. Basically, StarFOX is a quartet of small satellites that work in tandem — a satellite “swarm,” as it’s sometimes called. This concept isn’t entirely new, but there’s something that…

Satellites in space watched Hurricane Debby roar across Florida on Monday, bringing with it potentially record-setting rainfall and dangerous 80 mph (129 km/h) winds. NOAA’s GOES-East satellite recorded real-time views of Debby as it watched the hurricane unleash its force across the southeastern U.S. The footage, gathered from the satellite’s position about 22,236 miles (35,785 kilometers) above Earth’s equator, shows Debby strengthening in the Gulf of Mexico on Sunday, swirling dangerously close to Florida. Debby made landfall at Steinhatchee, Florida around 7 a.m. ET (1100 GMT) on Aug. 5 as…

The second-largest wildfire of 2024 continues to rage in northern California, and satellites are watching the destruction unfold. The Park Fire wildfire is currently burning north of Sacramento and has already consumed more than 560 square miles (1,455 square kilometers), an area larger than the city of Los Angeles. It is already the largest wildfire California has experienced this year. As of July 29, the fire was only 12% contained, according to InciWeb, a wildfire information service operated by the U.S. National Interagency Fire Center. As the fire continues to…

For the second time in a row, Lockheed Martin will be at the forefront of the creation of National Oceanic and Atmospheric Administration (NOAA)’s next generation weather satellites. Last month, National Aeronautics and Space Administration (NASA) awarded the aerospace company a $2.27 billion contract to develop and manufacture spacecraft for the next generation of NOAA satellites that will follow the Geostationary Operational Environmental Satellite (GOES) series, Geostationary Extended Observations (GeoXO). The contract includes developing three initial spacecraft and will also allow the option for an additional four. Work on the…
