WASHINGTON — The Space Development Agency (SDA) wants to give commercial space companies a chance to prove their mettle for future military satellite contracts. The agency on May 31 released a solicitation for its “Hybrid Acquisition for Proliferated LEO” (HALO) program, which aims to establish a pool of pre-approved vendors eligible to compete for upcoming

If traversable wormholes exist, we could potentially detect their plasma blasts Rostislav Zatonskiy / Alamy Wormholes that are surrounded by matter, like the ring that gathers around a black hole, could create strange rotating clouds of hot plasma. Anything that falls in one end could shoot out the other at 200 million kilometres per hour,

TAMPA, Fla. — Federal Communications Commission chair Jessica Rosenworcel proposed new rules May 29 to cover the risk of debris-generating accidental explosions in space. The new rules would require applicants to assess and limit the probability of accidental explosions to less than one in a thousand for each satellite they submit for approval. The probability metric

md zakirul mazed konok/Alamy The past few years have seen a significant rise in inflation in many countries, driven by a range of factors from pandemic-fuelled shortages to the war in Ukraine. But even now, as inflation is falling, prices are still rising, albeit more slowly. This subtlety is often missed, intentionally or otherwise, by

TAMPA, Fla. — A communications satellite order from Japan’s flagship operator has brought the geostationary orbit (GEO) market back to par with last year. SKY Perfect JSAT said May 27 it had ordered the JSAT-31 satellite from Europe’s Thales Alenia Space for a launch in 2027 to provide broadband across Japan, Australia, New Zealand, Southeast

Joel Redman/Gallery Stock If you were to take one step to improve your health, what would it be: change what you eat, be more active or invest more time in your friendships?

HELSINKI — China’s experimental reusable spacecraft has released an unknown object into orbit while conducting its third mission. U.S. Space Force space domain awareness teams cataloged the object as 59884 (International designator 2023-195G). The suspected spaceplane launched Dec. 14, 2023 and has been in orbit 164 days. The object appears to have been released May
