SpaceX's Starship, the most powerful rocket ever built, must remain grounded while Elon Musk's company completes dozens of corrective actions to prevent a repeat of the spectacular explosion that marred its first orbital test flight, regulators said Friday.
The 63 steps include "redesigns of vehicle hardware to prevent leaks and fires, redesign of the launch pad to increase its robustness," Viasat researching more portable satcoms terminals for dismounted soldiers

Virgin Galactic notches fourth spaceflight in four months

Virgin Galactic on Friday announced it had sent three paying customers on an hour-long journey to space and back, racking up its fourth successful flight in as many months.
The private astronauts aboard the Galactic 03 mission were among the first people to buy their tickets from the company founded by British billionaire Richard Branson in 2004.
American real estate entrepreneur Ken Baxter, South Africa-born conservationist Timothy Nash, and British engineer and entrepreneur Adrian Reynard took their places aboard the rocket-powered spaceplane VSS Unity, along with Virgin Galactic's astronaut instructor Beth Moses.
"What a thrilling day for our three new private astronauts and the entire team at Virgin Galactic," said CEO Michael Colglazier.
Scientists study distributed satellite cluster laser networking algorithm with double-layer Markov DRL architecture

With the development of satellite networks, space-air-ground integrated networks, and the Internet of Things, the future giant constellations, high-resolution Earth observation, human-crewed spacecraft, space stations and other space-based information systems have put forward an increasingly urgent demand for large-capacity space networking and information transmission.
The space distributed satellite cluster (DSC) overcomes the resource constraints and technical bottlenecks of single-satellite platforms by using multiple heterogeneous satellites in the same orbit to cooperate with distributed payloads to achieve large-capacity high-speed networking and information transmission and exchange in space, providing an effective solution for the above-mentioned needs.
The high-speed variation of relative positions of multi-satellites in the same orbit and the visible state constraints of satellite-borne optical phased array antennas cause the topology of DSC to be dynamically time-varying and intermittent link interruptions. It is necessary to solve the problems of rapid topology reconstruction and dynamic continuous networking under these two situations.

Bound for a metal-rich asteroid of the same name, the Psyche mission is targeting Oct. 5 to launch from NASA's Kennedy Space Center in Florida.
The spacecraft's solar arrays are folded like an envelope into their stowed position. Xenon gas - fuel for the journey to the asteroid belt - is loaded. All four thrusters have passed their final tests. Engineers have confirmed the massive high-gai NASA's completes Oxygen-Generating Experiment MOXIE

Riding with the Perseverance rover, the instrument has proved to be a viable technology for astronauts on Mars to produce oxygen for fuel and breathing. When the first astronauts land on Mars, they may have the descendants of a microwave-oven-size device to thank for the air they breathe and the rocket propellant that gets them home. That device, called MOXIE (Mars Oxygen In-Situ Resource Utiliz On the road to spotting alien life

In early August, scientists and engineers gathered in a small auditorium at Caltech to discuss how to build the first space telescope capable of detecting life on planets like Earth. The proposed mission concept, called the Habitable Worlds Observatory (HWO), would be the next powerful astrophysics observatory after NASA's James Webb Space Telescope (JWST). It would have the ability to study sta Camera hack lets Solar Orbiter peer deeper into Sun's atmosphere

Scientists have used Solar Orbiter's EUI camera in a new mode of operation to record part of the Sun's atmosphere at extreme ultraviolet wavelengths that has been almost impossible to image until now. This new mode of operation was made possible with a last-minute 'hack' to the camera and will almost certainly influence new solar instruments for future missions.

The humble neutrino, an elusive subatomic particle that passes effortlessly through normal matter, plays an outsized role among the particles that comprise our universe. To fully explain how our universe came to be, we need to know its mass. But, like so many of us, it avoids being weighed.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years old. The result provides astronomers with vital clues about how the magnetic fields of galaxies like our own Milky Way came to be.
