The experimental jet was built to kill the sonic boom. First, it has to survive going supersonic.

NASA’s Fermi telescope may have finally uncovered the magnetic powerhouse behind the universe’s brightest supernovae. An international team of astronomers analyzing observations from NASA’s Fermi Gamma-ray Space Telescope has found what appears to be the first convincing detection of gamma rays from a rare type of extraordinarily bright stellar explosion known as a superluminous supernova.

Forty years ago, the future seemed just around the corner—and the vehicle that was going to take us there was NASA's Space Shuttle. Originally envisioned as part of a larger integrated space transportation system, the shuttle was billed as a fully reusable vehicle, totally unlike the one-and-done capsules of the fading Apollo era, capable of making monthly (and perhaps even weekly) ferry flights to low Earth orbit.
The shuttle, it was hoped, would transform human space flight from extraordinary to mundane. Brands like Coke and Pepsi were quick to hop aboard and expand the Cola Wars into space, and there were even plans to blast Sesame Street's Big Bird into orbit.
The loss of Challenger in January 1986—carrying educator Christa McAuliffe, who would have been the first private citizen in space—put the kibosh on all of that. The shuttle, while fantastically advanced, would never be the vehicle to help humankind slip all of our surly bonds, so to speak. Even operating at its most frantic peak in 1985 just before Challenger's loss, the shuttle hardware managed a maximum of nine flights in one calendar year; for most of the 1990s, it performed at five or six flights per year. Civilians in space—to say nothing of Big Bird—would have to wait.

NASA satellites designed to observe cyclone wind speeds and collapsing ice sheets have also proven capable of identifying the approximate locations of GPS jammers. That could help monitor high-risk areas for aircraft and ships navigating the growing prevalence of GPS interference worldwide.
Two different NASA satellite systems showed how they could locate a known but mysterious GPS jammer within several kilometers of its position in Iran, according to an experiment by Sean Gorman, CEO and cofounder of the location-based technology company Zephr.xyz that was detailed in the magazine GPS World. Such jammers use strong signals to overpower the weaker radio signals coming from US-operated GPS satellites and other global navigation satellite systems.
Such NASA satellites cannot perform “near-real time monitoring” or pinpoint the exact location of GPS jammers, said Clara Chew, principal scientist and lead of the GNSS systems and data team at the California-based satellite manufacturer Muon Space, who was not involved in the study. But Chew told Ars that identifying the approximate locations of GPS jammers “could potentially be helpful for flight planning” or for “indicating high risk areas for maritime shipping.”

NASA officials announced contract awards for the initial elements of a lunar base on Tuesday, including two rovers that will provide mobility to astronauts.
With the series of announcements, NASA Administrator Jared Isaacman sought to maintain momentum around a Moon Base initiative revealed two months ago as part of the space agency's return to the Moon. "For those waiting patiently, the grand return is close at hand, and we will not slow down," he said.
The manager for the lunar base, Carlos Garcia-Galan, said the space agency had selected two companies, Astrolab and Lunar Outpost, to build approximately 1-ton rovers that would be ready for delivery to the Moon in 2028. Astrolab will receive $219 million for its "CLV-1" rover, and Lunar Outpost $220 million for its "Pegasus" rover, building upon initial contracts awarded two years ago. Each rover is expected to have a range of 200 km and be capable of driving autonomously, with guidance from operators on Earth, in addition to being driven by astronauts.

SpaceX launched the first test flight of its upgraded Starship rocket and Super Heavy booster Friday, with mostly positive results.
The powerful rocket, propelled by 33 methane-fueled main engines, climbed away from SpaceX's Starbase launch facility in South Texas at 5:30 pm CDT (6:30 pm EDT; 22:30 UTC) Friday. Within a few seconds, the 408-foot-tall (124-meter) rocket, the largest ever built, cleared the launch tower and turned onto an eastward heading over the Gulf of Mexico.
Starship splashed down on target in the Indian Ocean a little more than an hour later to conclude the first flight of the latest version of SpaceX's stainless-steel mega-rocket. Starship V3 fared better on its debut than the first flights of Starship V1 and V2 in 2023 and 2025. Both past versions of Starship broke apart during launch on their inaugural flights.

NASA Administrator Jared Isaacman sent a long email to employees on Friday morning outlining several structural changes that are intended to make the sprawling agency more efficient and allow it to better accomplish major goals, such as returning to the Moon and building a base there.
"I believe it is imperative to concentrate resources towards the highest priority objectives in the National Space Policy and liberate the best and brightest from needless bureaucracy and obstacles that impede progress," Isaacman wrote in his 3,000-word letter.
Isaacman's message stressed that no one at NASA will lose their jobs, and no field centers will be closed as part of these changes. Rather, the overall intent is to improve operational efficiency and focus on the agency's core missions. Isaacman laid these out as: execute on the Artemis Program to return humans to the Moon; build an enduring Moon Base; develop a "Space Reactor Office" to get America underway on nuclear power in space; ignite an economy in low-Earth orbit; and build more X-planes and launch more science missions.
