Splitting rockets: What would a military-NASA collaboration really mean?John Matson
built. However, Starship's hull is stainless steel, which makes it more durable than other rockets but also extremely heavy. At 5,000 tons, it has twice the dry mass of the SLS. NASA's rocket can make it all the way to the moon in one launch, but Starship will have to refuel in...

To drop back to its original energy level, the "stimulated" electron must release the energy it has absorbed, which is emitted as a photon: a single packet oflight. Physicist Anita Chandran, of the European Southern Observatory, explains it with emojis: ...
The Sick Building Syndrome is one the Gateway Foundation wants to avoid in this new territory, following in the footsteps of NASA which has only approved certain materials that have a minimum level of off-gassing. Where there’s reduced gravity, floating particles could...
Tonopah Test Range (Nevada):Also part of the broader Nevada National Security Site. Thevast area of flat terrainis ideal for rockets and low-altitude, high-speed aircraft operations. All of these locations are shrouded in secrecy, but none have the same cultural mystique as Area 51. ...
Experts have been discussing the space junk problem since the 1960s, leading NASA’s Donald Kessler to author a groundbreaking 1978 report on the chain of reactions that could occur once debris reached a certain level—an effect now referred to as the Kessler syndrom...
These satellites will continue to help cover the continental U.S., Canada and the U.K. At the same time, NASA and SpaceX have come to an information-sharing agreement to help avoid orbital collisions. SpaceX also revealed its next-gen Starlink V2 Mni satellites which now use the E-b...
The boosters are hard to spot against the bright blue backdrop. But soon the two light up their engines high in the sky — the entry burn, which slows the rockets down when re-entering the Earth’s atmosphere. The crowd shrieks. We lose sight of the boosters again when the burn is ...
SpaceX is the only company in the world that routinely guides its rockets back to a pinpoint landing after launch, the maneuver that triggers a startling sonic boom. The company mastered that technique over the course of a decade flying its workhorse Falcon 9 rockets. Lead study author Kent ...
