Washington (AFP) - NASA and the US military said Wednesday they had selected defense contractor Lockheed Martin to develop a nuclear powered rocket, with a view to using the technology for missions to Mars. The Demonstration Rocket for Agile Cislunar Operations (DRACO) program may launch as soon as 2027, officials said on a call. Nuclear thermal propulsion (NTP) systems could cut journey times, increase fuel efficiency, and require less propellant, meaning future spacecraft could carry larger payloads than today's best chemical rockets. NTP works by pumping a liquid propellant, in DRACO's cas...

Washington (AFP) - NASA's Space Launch System rocket is heading back to its assembly building for repairs next week, pushing the earliest possible launch date for its uncrewed test flight to the Moon to later this summer, officials said Monday. Since April 1 the space agency has been unsuccessfully attempting a key "wet dress rehearsal" test, so dubbed because it involves loading liquid propellant. The procedure is meant as a run-through of launch operations, including a final countdown to within ten seconds before blast off, but without actually firing the engines. But NASA teams have encount...

Washington (AFP) - NASA's massive new rocket eased onto its launchpad Friday, ready for a battery of tests that will clear it to blast off to the Moon this summer on an uncrewed flight. It left the Kennedy Space Center's Vehicle Assembly Building Thursday evening and began a nearly 11-hour journey on a crawler-transporter to the hallowed Launch Complex 39B, arriving at 4:15 am. Around 10,000 people had gathered to watch the event. Huge rocket, huge cost - With the Orion crew capsule fixed on top, the Space Launch System (SLS) Block 1 stands 322 feet (98 meters) high -- taller than the Statue o...

Washington (AFP) - NASA's massive new rocket is poised to make its first journey to a launchpad on Thursday ahead of a battery of tests that will clear it to blast off to the Moon this summer. It will leave the Kennedy Space Center's Vehicle Assembly Building at 5:00 pm Eastern Time (2100 GMT) and begin its glacially slow, 11-hour crawl on a transporter to the hallowed Launch Complex 39B, four miles (6.5 kilometers) away. Here's what you need to know. Huge rocket, huge cost - With the Orion crew capsule fixed on top, the Space Launch System (SLS) Block 1 stands 322 feet (98 meters) high -- ta...

Beijing (AFP) - A large segment of a Chinese rocket re-entered the Earth's atmosphere and disintegrated over the Indian Ocean on Sunday, China's space agency said, following fevered speculation over where the 18-tonne object would come down. Officials in Beijing had said there was little risk from the freefalling segment of the Long March-5B rocket, which had launched the first module of China's new space station into Earth orbit on April 29. But the US space agency NASA and some experts said China had behaved irresponsibly, as an uncontrolled re-entry of such a large object risked damage and ...
