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.

NASA confirmed Thursday that the Russian segment of the International Space Station has begun leaking atmosphere into space again. It's an old problem that NASA recently hoped was resolved.

For more than half a decade, engineers from Roscosmos and NASA have been tracking the leak rate from a small Russian module attached to the space station that leads to a docking port. The source of these leaks, microscopic structural cracks, have been difficult to find and address.

In January, NASA said that after multiple inspections and sealant applications, the pressure inside this segment, known as the PrK module, had reached a "stable configuration." The PrK module is essentially a transfer tunnel attached to the Zvezda Service Module on the Russian segment of the space station.

Not quite halfway through a six-year sojourn through the Solar System, a NASA spacecraft used a close encounter with Mars last week as a dress rehearsal for its arrival at the Solar System's largest metal asteroid in 2029.

The Psyche mission launched more than two-and-a-half years ago, in October 2023, from Kennedy Space Center, Florida, to kick off a journey of some 2.2 billion miles (3.6 billion km) to reach its unexplored namesake, the asteroid Psyche. The robotic research mission got an initial lift from a powerful SpaceX Falcon Heavy rocket. It uses plasma engines to gradually build up the impulse needed to reach its destination in the asteroid belt, between the orbits of Mars and Jupiter.

A flyby of Mars last Friday gave the spacecraft its most significant boost since launch. Navigators at NASA's Jet Propulsion Laboratory in California set up the spacecraft for a course taking it 2,864 miles (4,609 km) from the Martian surface, well above the planet's tenuous atmosphere. Psyche used Martian gravity like a slingshot to gain enough speed to reshape its orbit around the Sun, putting the probe on a path to intercept its asteroid target.

There are more opportunities to access space than ever, thanks to a bevy of commercial rockets, some with reusable boosters, led by SpaceX's workhorse Falcon 9. So why is NASA launching fewer telescopes and planetary science missions than it did a quarter-century ago?

The answer is complex. It is not necessarily the money. The space agency's science budget this year is $7.25 billion, roughly the same as it was in 2000, adjusted for inflation. This is despite attempts by the Trump administration to drastically reduce NASA science funding.

In the early months of his tenure, NASA Administrator Jared Isaacman's focus has been on human spaceflight and the Moon. This isn't terribly surprising given NASA's wildly successful Artemis II mission carrying four astronauts around the Moon last month. Since taking office in December, Isaacman has announced an overhaul of the Artemis program, canceling a space station to be built in orbit around the Moon in favor of construction of a base on the lunar surface.
