Vast announces line of high-power satellite buses
WASHINGTON — Commercial space station developer Vast is moving into satellite manufacturing with a line of high-power satellite buses.
The company announced May 19 Vast Satellite, a product line that uses the technologies Vast developed for commercial space stations to make satellite buses designed for applications ranging from broadband communications to orbital data centers.
The first product is a bus that provides 15 kilowatts of power. The flat-panel bus, with primary dimensions of 2.2 by 3.6 meters, has a dry mass of 700 kilograms and can host payloads of at least 350 kilograms. Designed for initial use in low Earth orbit, the bus has an electric propulsion system that provides more than 500 meters per second of delta-v, or change in velocity.
The “impossible” LED that could change everything
Scientists at the University of Cambridge have achieved what was once considered impossible by electrically powering insulating nanoparticles to create a completely new kind of LED. Using tiny organic “molecular antennas,” the team found a way to funnel energy into materials that normally cannot conduct electricity, producing ultra pure near infrared light with remarkable efficiency.
Schrödinger’s clock: Time could tick faster and slower at the same time
Time might be even stranger than Einstein imagined. Physicists are now exploring the possibility that a single clock could exist in a quantum superposition, ticking both faster and slower at the same time — almost like Schrödinger’s cat being both alive and dead simultaneously. Using incredibly precise atomic clocks and cutting-edge quantum technologies, researchers believe they may soon be able to test this bizarre prediction in the lab for the first time.
