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 ..
The Pentagon has canceled a ground control system for the US military’s GPS satellite navigation network after the program’s enduring problems “proved insurmountable,” the US Space Force announced in a press release Monday. The Global Positioning System Next-Generation Operational Control System, known by the acronym OCX, was officially canceled by Michael Duffey, the Pentagon’s defense acquisition ..

The third flight of Blue Origin’s heavy-lift New Glenn launcher began Sunday with the company’s first successful reflight of an orbital-class booster, but ended with a setback for Jeff Bezos’ flagship rocket, a key element in NASA’s Artemis lunar program. The 321-foot-tall (98-meter) New Glenn launch vehicle ignited its seven methane-fueled BE-4 engines at 7:25 ..
