WASHINGTON — The Japanese and Canadian space agencies announced plans May 26 to send small rovers to the moon in the next several years, as Lockheed Martin unveiled a partnership with automaker General Motors to propose a rover for NASA’s Artemis program. The Japanese space agency JAXA said it is working with several Japanese companies
SEOUL, South Korea — South Korea signed the Artemis Accords May 27, becoming the 10th signatory to the pact that governs norms of behavior for those who want to participate in the NASA-led Artemis lunar exploration program. On the same day, South Korea and the United States signed an agreement on “civil global navigation satellite

WASHINGTON — A delay of up to two years in the next New Frontiers planetary science mission competition won’t change the potential destinations for that mission. NASA announced May 12 it was delaying the release of a draft announcement of opportunity for the fifth New Frontiers mission from this October to as late as October
On July 4, 2026, the United States will celebrate the 250th anniversary of its independence. America should commemorate this historical milestone in 2026 by landing humans on the moon for the first time since 1972. Sending humanity back to the moon in 2026 is not only technically feasible, but it also fits squarely in the

SAN FRANCISCO – At the direction of the Biden Administration, the National Oceanic and Atmospheric Administration’s National Environmental Satellite, Data and Information Service (NESDIS) is adopting a portfolio approach. “For us that means not just launching one satellite at a time and building that satellite really well, but seeing how all the systems work together,”
Kendall: If confirmed ‘I’ll evaluate the plans and directions currently being implemented’ WASHINGTON — President Biden’s nominee to be secretary of the Air Force Frank Kendall told lawmakers May 25 he will ensure the Space Force gets the necessary resources to continue to stand up units and acquire new systems. During a Senate Armed Services
By: Hannah Pell Image credit: ProtoDUNE / CERN. Why does matter exist in the universe? Can we find evidence of proton decay, supporting Einstein’s dream of unified forces? These questions, among a host of others, are very much open for debate within high-energy physics, and one particle has the potential to help answer all of

Rep. Jim Cooper worries that Space Force acquisitions are headed down a similar path as past Air Force programs WASHINGTON — The U.S. Space Force has plans to acquire billions of dollars worth of new satellites over the coming years and needs to make sure it avoids the missteps that plagued previous acquisitions, said the
TAMPA, Fla. — A OneWeb-led group has secured government funding to launch a beam-hopping satellite in 2022, demonstrating how a spacecraft could switch its coverage area in real-time to respond to surges in demand. OneWeb, which has launched a third of its initial 650-strong constellation to low Earth orbit (LEO), said the so-called Joey-Sat spacecraft
Patterns of grey matter degeneration seen within two variants of FTD (A, B) differ from the pattern seen in Alzheimer’s disease (C). (Courtesy: S R Shaw et al Brain 10.1093/brain/awab032) The researchers then performed voxel-based morphometry analysis of participants’ whole-brain MR images to examine voxel-by-voxel changes in grey matter signal intensities. They discovered that that
WASHINGTON — The European Space Agency has issued contracts to two European industry groups to begin concept studies of lunar satellite systems that would provide communications and navigation services. ESA announced the awards May 20 to two consortia, one led by Surrey Satellite Technology Ltd. (SSTL) and the other by Telespazio, to begin studies for
The Space Enterprise Consortium plans to issue a request for prototype proposals by June 30 WASHINGTON — The U.S. Space Force next month will solicit industry bids for deep-space radar sensors that can track active satellites and debris in high orbits above 22,000 miles. One or more contractors will be selected to develop prototype concepts
Tungsten component produced by 3D printing using electron beam melting. Photo: Markus Breig, KIT Tungsten has many excellent properties. It resists corrosion, and its melting point of 3422 °C is the highest of all metals, making it an ideal material for components that operate at extreme temperatures. There is a problem, though: it is highly
HELSINKI — China’s Zhurong rover descended onto the surface of Mars late May 21, a week after the vehicle’s historic landing in Utopia Planitia. The China National Space Administration (CNSA) announced Saturday that the six-wheeled Zhurong had reached the surface at 10:20 p.m. Eastern Friday. The rover will now begin science and exploration tasks in
