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.

Tailored drinks could provide space nutrition

How could customizable drinks help provide astronauts on future, long-term space missions with the proper levels of nutrition? This is what a recent study published in ACS Food Science & Technology hopes to address as a team of researchers investigated novel methods for improving future astronaut diets. This study has the potential to help scientists, mission planners, and astronauts develop improved dietary plans, specifically as space mission durations are aimed to increase in the coming years.

For the study, the researchers introduced beverage nanoemulsion drinks, with emulsion drinks being a common drink that typically consists of a blended mixture of two normally non-mixable substances like an oily substance and watery substance with microscopic droplets within the liquid since they don’t full mix together. In this case, the researchers propose nanoemulsion drinks with even smaller droplets and consist of water and Omega-3 fatty acids (fish oil), which provide bone and muscle protection against space radiation.

In the end, the researchers found that customizable drinks with a variety of sweetness levels and flavors are the best options. Going forward, the researchers aspire to test the tastiness of the beverages under microgravity conditions, as they note the drinks taste like typical flat sodas after carbonation loss.
