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
