Editor’s Note: This article was updated Nov. 20, 2024 shortly after BioSentinel’s mission marked two years of operation in deep space. Astronauts live in a pretty extreme environment aboard the International Space Station. Orbiting about 250 miles above the Earth in the weightlessness of microgravity, they rely on commercial cargo missions about every two months to deliver new … Read more
The Advanced Composite Solar Sail System, which launched in April 2024, and deployed its reflective sail in August, is currently orbiting approximately 600 miles (1,000 kilometers) above Earth and is frequently visible in the night sky to observers in the Northern Hemisphere. Fans of the spacecraft can look for the sail in the night sky using … Read more
In May 2024, a geomagnetic storm hit Earth, sending auroras across the planet’s skies in a once-in-a-generation light display. These dazzling sights are possible because of the interaction of coronal mass ejections – explosions of plasma and magnetic field from the Sun – with Earth’s magnetic field, which protects us from the radiation the Sun … Read more
NASA is advancing an innovative approach to enabling commercial inspection of defunct, or inoperable, satellites in low Earth orbit, a precursor to capturing and repairing or removing the satellites. The agency has awarded Starfish Space of Seattle, Washington, a Phase III Small Business Innovation Research (SBIR) contract to complete the Small Spacecraft Propulsion and Inspection … Read more
NASA’s TBIRD (TeraByte InfraRed Delivery) demonstration and its host spacecraft — the PTD-3 (Pathfinder Technology Demonstrator-3) — have completed their technology demonstration. The TBIRD payload spent the past two years breaking world records for the fastest satellite downlink from space using laser communications. NASA’s PTD series leverages a common commercial spacecraft to provide a robust … Read more
“I’m proud of how the team responded to the situation and is making the best use of the time we have in orbit,” said Jeremy Perkins, BurstCube’s principal investigator at Goddard. “Small missions like BurstCube not only provide an opportunity to do great science and test new technologies, like our mission’s gamma-ray detector, but also … Read more
A pair of CubeSats from NASA’s Pathfinder Technology Demonstrator, or PTD, series lifted off on SpaceX’s Transporter-11 rideshare mission at 11:56 a.m. PDT Friday, August 16, from Vandenburg Space Force Base in California. The two small satellites, PTD-4 and PTD-R, will help advance NASA’s efforts to validate novel technologies and increase small spacecraft capabilities in … Read more
NASA announced a new round of opportunities for CubeSat, developers to build spacecrafts on that will fly on upcoming launches through the agency’s CSLI (CubeSat Launch Initiative). CubeSats are a class of small spacecraft called nanosatellites. The initiative provides space access to U.S. educational institutions, certain non-profit organizations, and informal educational institutions such as museums and science centers, as well as … Read more
NASA launched CURIE (CubeSat Radio Interferometry Experiment) as a rideshare payload on the inaugural flight of ESA’s (European Space Agency) Ariane 6 rocket, which launched at 4 p.m. GFT on July 9 from Europe’s Spaceport, the Guiana Space Center in Kourou, in French Guiana. Designed by a team from the University of California, Berkeley, CURIE … Read more
“This is a very ambitious and very exciting mission,” said Principal Investigator David Sundkvist, a researcher at the University of California, Berkeley. “This is the first time that someone is ever flying a radio interferometer in space in a controlled way, and so it’s a pathfinder for radio astronomy in general.” Source link
