NASA Space Technology In June, engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, unveiled an innovative, 11-inch hybrid rocket motor testbed.The new hybrid testbed, which features variable flow capability and a 20-second continuous burn duration, is designed to provide a low-cost, quick-turnaround solution for conducting hot-fire tests of advanced nozzles and other rocket engine hardware, composite materials, and propellants.Solid rocket propulsion remains a competitive, reliable technology for various compact and heavy-lift rockets as well as in-space missions, offering low propulsion element mass, high energy density, resilience in extreme environments, and reliable performance.“It’s time consuming and costly to put a new solid rocket motor through its paces – identifying how materials perform in extreme temperatures and under severe structural and dynamic loads,” said Benjamin Davis, branch chief of the Solid Propulsion and Pyrotechnic Devices...

NASA Space Technology To celebrate two years since the James Webb Space Telescope (JWST) started sending images back to Earth, NASA has released yet another stunning image taken by the revolutionary space telescope.The second-anniversary JWST image shows two interacting galaxies that make up a single object called Arp 142, which appears like a cosmic penguin with its cosmic egg. Fittingly for a celebration of the JWST's two years of science results, the new image is a two-for-two. Arp 142's Penguin and Egg scene comprises two interacting galaxies located around 326 million light-years from Earth in the constellation of Hydra. It has been observed before, but never in as much detail as this view from the JWST has allowed.Related: James Webb Space Telescope sees an ancient black hole dance with colliding galaxiesThe distorted spiral galaxy at center,...

NASA Space Technology Boeing Starliner astronauts Sunita Williams and Barry “Butch” Wilmore spoke to reporters Wednesday and said they’re confident the spacecraft will bring them safely back to Earth. In the meantime, Williams said, they’re both enjoying their extended stay aboard the International Space Station. Image: NASA TVThe crew of Boeing’s Starliner spacecraft said Wednesday they’re confident the capsule will carry them safely back to Earth at the end of their extended stay aboard the International Space Station, despite helium leaks in the ship’s propulsion system and trouble with maneuvering thrusters.Launched June 5, commander Barry “Butch” Wilmore and co-pilot Sunita Williams originally expected to spend about eight days in space, putting the Starliner through its paces in the ship’s first piloted test flight.But the helium leaks and thruster issues have prompted NASA to extend their...

NASA Space Technology Amyloid plaques are misfolded proteins aggregates beetween neurons, Alzheimer’s disease illustration (Credits: Getty Images/iStockphoto)A nasal spray that helps ‘wash’ Alzheimer’s-causing proteins out of the brain could one day offer hope to millions who suffer from the disease.Alzheimer’s is the most common form of dementiaaffecting more than 940,000 people in the UK alone. As the world’s population ages, the number is increasing, expected to almost double every 20 years.While the causes of the disease are still not fully understood, scientists have been studying the build-up of tau proteins in the brain that lead to cognitive decline. The proteins clump and form tangles, disrupting signals along neurons, or brain cells.Now, a team from the University of Texas Medical Branch (UTMB) has found a potential way to get rid of the proteins.The team developed a...
