NASA’s Swift Mission Ends, Leaves Behind Scientific Bonanza
NASA’s Neil Gehrels Swift Observatory has ended its science mission now that the spacecraft is orbiting less than 171 miles (275 kilometers) above Earth’s surface. The greater atmospheric drag at this height prevents the satellite’s telescopes from steadily gazing at their astronomical targets. Swift conducted its final observation on Oct.
Securing our frontier model training environment unverified
OpenAI explains how we strengthened containment for frontier model training and evaluation, including offline environments and high-compute red-teaming.
White Dwarfs Are Actually…Yellow, Green, Pink, and Purple?
The universe hosts a myriad of star types, including supergiants, giants, main sequence, red dwarfs, brown dwarfs, white dwarfs, and neutron stars. What makes these stars stand out are just their sizes, but their colors, as each one hosts a distinct color based on their surface temperature, specifically orange, red, blue, and white based on cooler to hotter temperatures.
SpaceX launches Starlink satellites from California as Falcon 9 cadence slows (video)
SpaceX launched its newest batch of Starlink broadband internet satellites today (Oct. The spacecraft, Starlink Group 15-15, were stacked 27 high inside the payload fairing of a SpaceX Falcon 9 rocket, which lifted off from Pad 4E at Vandenberg Space Force Base at 6:48 p.m. EDT (2248 GMT; 3:48 p.m. local time in California).
Two sources, one subject: what does each one report?

NASA, Partners Accelerate Lander Development for 2028 Moon Missions
As NASA returns humans to the lunar surface and establishes a long-term presence on our closest celestial neighbor, the agency and commercial human landing system providers Blue Origin and SpaceX have streamlined the designs and changed both concepts of operations for its future crewed landers. Since NASA established initial contracts with Blue Origin and SpaceX for crewed missions to the Moon, the agency has redefined Artemis III to demonstrate rendezvous and docking capabilities between test versions of landers from each provider and the agency’s Orion spacecraft in low Earth orbit next year.
NASA Artemis Update: SLS Stacking, Sortie Suit, Dual 2028 Paths
NASA released its October Artemis Update on Friday, covering the near-term status of the Space Launch System (SLS), a lighter “sortie” version of the lunar spacesuit, and two parallel architectures for delivering astronauts to the lunar surface. Many of the elements had been discussed in prior program updates. However, the briefing did include the first public images of crew cabin hardware from both SpaceX and Blue Origin.
