Data collected by the Soil moisture And Nitrogen Detection Satellite, known as SANDS, could

WASHINGTON — The Defense Advanced Research Projects Agency is kicking off a study to develop an “analytical framework” to guide development of integrated lunar infrastructure over the next decade. DARPA announced the 10-Year Lunar Architecture, or LunA-10, project Aug. 15, seeking ideas from both potential developers or lunar power, communications, navigation and other infrastructure as

WASHINGTON — Artificial intelligence startup Wallaroo Labs won a $1.5 million contract from the U.S. Space Force to continue the development of machine learning models for edge computers in orbit. The New York-based company, known as Wallaroo.ai, is partnered with New Mexico State University for the Small Business Technology Transfer Phase 2 contract, announced Aug.

WASHINGTON — SkyWatch, a satellite data distributor based in Ontario, Canada, announced a new imagery product that combines radar and optical images.   SkyWatch operates a platform called EarthCache that gives its customers access to commercial satellite data. The company said there is now a growing demand for integrated images that combine visually appealing pictures from

WASHINGTON — Momentus recently cut its workforce by 30% as the cash-strapped company seeks to reduce its costs while looking for “strategic options” to raise funding. In an Aug. 14 earnings call about its second quarter financial results, Eric Williams, chief financial officer of Momentus, said that the company reduced its headcount, including both full-time

TAMPA, Fla. — Terran Orbital expects to get $180 million this year from Rivada Space as it prepares to build 300 satellites for the venture, even as plans to fund the full $2.4 billion manufacturing contract remain under wraps. It would be the first significant revenues Terran Orbital has gained from Rivada under a contract

WASHINGTON — BAE Systems, a defense and security conglomerate based in the United Kingdom, announced Aug. 17 it intends to acquire Ball Aerospace for $5.5 billion.

When the materials scientist Ross Colman and colleagues read a preprint claiming that a material called LK-99 is a superconductor at room temperature and ambient pressure, they set out to replicate the result in their lab. But unlike other scientists doing the same thing, Colman’s group decided to share their work with the public in

Wide open question: binary-star observations back MOND.(Courtesy: NASA Goddard Space Flight Center/Chris Smith (USRA)) A new study of data from the European Space Agency’s Gaia space mission claims to have found evidence of gravity acting contrary to the predictions of Newton and Einstein, but not everyone agrees that this is the smoking gun for a
