The bottom line: Astronauts likely won’t exceed Artemis II’s distance from Earth on most lunar landing missions, but it’s conceivable that on some occasions, circumstances will align to propel a crew a little beyond the 252,756-mile mark. The sure bet will come when someone finally takes aim at Mars. “Big disappointment” Haise, the only Apollo ..

The US Space Force released a list Friday of a dozen companies working on Space-Based Interceptors for the Pentagon’s Golden Dome initiative, a multilayer defense system to shield US territory from drones and ballistic, hypersonic, and cruise missile attacks. The roster of Golden Dome Space-Based Interceptor (SBI) contractors, some of which were previously reported, includes ..
On top of that, when analyzing the beaks, the team noticed a distinct pattern. The wear wasn’t uniform. The right edge of the jaw was consistently more worn down, chipped, and scratched than the left. The team concluded this asymmetry wasn’t an accident but a proof of lateralized behavior. It’s a tendency we observe in ..
Shortly after their discovery, carbon nanotubes seemed to be a material wonder. There were metallic and semiconducting forms; they were tiny and incredibly light; and they could only be broken by tearing apart chemical bonds. The ideas for using them seemed endless. But then the reality of working with them set in. It was hard ..
[embedded content] The gravitational constant, affectionally known as “Big G,” is one of the most fundamental constants of our universe. Its value describes the strength of the gravitational force acting on two masses separated by a given distance—or if you want to be relativistic about it, the amount a given mass curves space-time. Physicists have ..
“Russia remains a capable space power, even while its space industry suffers from systemic underfunding, quality control issues, international sanctions, and export controls,” US intelligence agencies wrote in their annual unclassified threat assessment released earlier this year. Russia’s space industry has far less money than the US and Chinese space programs. Russian factories produce fewer ..
Scientifically, it will be used to image exoplanets in distant orbits from their stars. But it also serves an engineering purpose: starting the development of a coronagraph for the planned Habitable Worlds Observatory that will need to be 100 times more effective at blocking out stars. Compared to something like the Webb Telescope, Roman is ..

Under the newly adopted policies, the Corps of Engineers must weigh the energy produced per acre for any projects under its oversight against the potential impact of alternative uses of the land. The Department of the Interior was ordered to make a similar consideration. For the purposes of a temporary injunction, that turned out to ..
