SpaceX describes surgical intervention before launch of latest crew mission (opens the original)
Read excerpt
A four-person crew rocketed into orbit Thursday from Cape Canaveral Space Force Station, Florida, heading for a six-month expedition on the International Space Station. Riding a Falcon 9 rocket and Dragon spacecraft, the four crew members departed from Space Launch Complex-40 at Cape Canaveral at 11:10 am EDT (15:10 UTC) Thursday. Nine minutes later, they were in orbit to begin closing in on the space station for docking Thursday evening. The launch was delayed from mid-September to replace a ba
NASA squeezed Treasury, vibe coded, and broke the mold in bid to save Swift (opens the original)
Read excerpt
An attempt to save NASA’s $500 million Neil Gehrels Swift Observatory from dropping out of orbit fell short, but the behind-the-scenes machinations required just to make a rescue possible deserve recognition, government and commercial space officials said in a recounting of the mission. The rescue mission was developed by Katalyst Space Technologies, working under a $30 million contract awarded by NASA last September. NASA gave Katalyst nine months to build and launch a satellite to capture Swif
SpaceX's Starship goes orbital, deploying first next-gen Starlinks (opens the original)
Read excerpt
SpaceX’s Starship rocket thundered into the sky over South Texas early Monday. It was the 14th test flight of the world’s most powerful launch vehicle. This time, however, the rocket’s massive upper stage squeezed out some extra oomph from its Raptor engines and accelerated to orbital velocity. On all of Starship’s previous flights, SpaceX intentionally dialed back the full capability of the rocket to fly a suborbital trajectory, slow enough for Earth’s gravity to pull the vehicle back into the
With PRIMA, NASA will try to build a billion-dollar space telescope in record time (opens the original)
Read excerpt
The first in a new class of space telescopes is on track to reach the launch pad in the early 2030s, NASA announced this week. The PRIMA mission will be the first of NASA’s Probe Explorers, a new line of observatories intended to do more science for less money. The agency’s space telescopes typically fall into lower-cost “Explorer-class” missions, with cost caps in the range of a few hundred million dollars, or flagship observatories like the recently launched Nancy Grace Roman Space Telescope,
The Roman telescope has enough gas for 22 years, double NASA's expectations (opens the original)
Read excerpt
NASA’s Nancy Grace Roman Space Telescope is gliding toward its distant observation post on a pinpoint trajectory so precise that engineers estimate the spacecraft’s fuel load will last twice as long as their initial expectations, the space agency confirmed Monday. The $4.3 billion observatory’s designers originally planned to load enough propellant into Roman’s four fuel tanks for a minimum lifetime of five years, plus a potential five-year mission extension. That was a conservative estimate. NA
