HELSINKI — China has laid out its pathway for robotic and crewed lunar and deep space exploration, with a number of missions building towards a permanent moon base. Three upcoming robotic missions will set in place landers, orbiters, relay satellites and test key technologies needed to begin construction of China’s International Lunar Research Station (ILRS)

SEOUL, South Korea – India’s space agency ISRO launched a one-ton Earth observation satellite and eight nanosatellites to sun-synchronous polar orbit Nov. 26 aboard the nation’s workhorse Polar Satellite Launch Vehicle (PSLV) rocket. The rocket lifted off from the Satish Dhawan Space Centre at 1:26 a.m. Eastern. The launch was live-streamed on YouTube, which showed

Calçada) Massive stars in their “red supergiant” phase become around 100 times fainter in the visible part of the electromagnetic spectrum in the last few months before they collapse and explode as a supernova. This is the finding of researchers from Liverpool

WASHINGTON — NASA’s Orion spacecraft entered a high-altitude orbit around the moon Nov. 25 in the latest major step in the Artemis 1 uncrewed test flight. The Orion spacecraft fired the main engine in its European Service Module at 4:52 p.m. Eastern for 88 seconds. The maneuver changed the velocity of the spacecraft by about

TAMPA, Fla. — Echostar said Nov. 22 that Maxar Technologies is providing compensation for production issues that have delayed the launch of its Jupiter 3 satellite to at least the first half of 2023. The satellite operator said Maxar is “providing relief on future payments” under an amended contract, which also “expands EchoStar’s recourse” if

The new clock’s frequency instability is less than 4×10-19. (Courtesy: J Pan) Physicists have transferred time and frequency information over a distance of more than 100 km in free space, far exceeding the previous record. The technique, which makes it possible to synchronize and monitor optical clocks in environments where optical-fibre-based connections are impractical, could

The satellite communications industry is on a mission to virtualize every possible piece of ground infrastructure to catch up with the age of cloud-based networks. Converting hardware into software installed and managed remotely via third-party data centers would give satellite operators more flexibility over their networks and speed up how quickly they can respond to
