NASA's Nancy Grace Roman Space Telescope is gliding toward its distant observation post on a pinpoint trajectory so precise that engineers estimate the spacecraft's fuel load will last twice as long as their initial expectations, the space agency confirmed Monday.

The $4.3 billion observatory's designers originally planned to load enough propellant into Roman's four fuel tanks for a minimum lifetime of five years, plus a potential five-year mission extension. That was a conservative estimate. NASA officials knew an on-target launch and perfect execution of the observatory's first post-launch course correction maneuver would leave Roman with a hearty fuel reserve.

"As a result of exquisite planning by our orbital dynamics team, brilliant execution by the operations team, and a precise launch from SpaceX, Roman has fuel for at least 22 years of potential science operations," Jamie Dunn, center director at NASA's Goddard Space Flight Center, said in a press release.

Air Force Secretary Troy Meink made the first public declaration Monday that the United States has placed "space control weapons" in orbit, an announcement that will surely reverberate in the power centers of Beijing and Moscow.

Space Force officials have previously expressed their interest in acquiring space-based weapons, and Pentagon leaders have become more open to discussing space warfare in recent years. Therefore, Meink's announcement Monday at the Air and Space Forces Association's annual Air, Space & Cyber Conference near Washington, DC, was not entirely unexpected.

“Today, we continue to ensure we remain ready to meet the challenges of evolving threats, wherever they exist. This is why the United States now has on-orbit space control weapons capable of defending the joint force against hostile adversary action,” Meink said in prepared remarks.

The European Space Agency is moving "full steam ahead" with development of a robotic mission to Venus after NASA officials determined they were unlikely to fulfill a commitment to provide a US-built radar instrument for the spacecraft, the mission's project scientist said.

The European orbiter, named Envision, will map the Venusian surface at 10 times higher resolution than the last radar mission sent to Venus by NASA in the 1990s. The planet is enshrouded in a blanket of thick clouds of sulfuric acid, rendering its mysterious surface unseen by optical cameras in orbit. Radar is the most effective way to penetrate the clouds of Venus to reveal the terrain below, and scientists will use Envision to look for signs of active volcanism.

NASA and ESA signed a memorandum of understanding in 2024 outlining their partnership on Envision. NASA agreed to supply a US-made synthetic aperture radar instrument, Envision's primary means of mapping the surface of Venus, along with providing tracking and communications support through NASA's Deep Space Network. In exchange, ESA would include US researchers on Envision's science team. Europe would build the Envision spacecraft and the rest of its science instruments and provide the launch on an Ariane 6 rocket.

Isar Aerospace, founded in 2018 by three students at a German university, successfully launched a privately developed rocket into low-Earth orbit Saturday from a Norwegian spaceport inside the Arctic Circle.

The two-stage rocket, named Spectrum, became the first fully commercial launch vehicle in Europe to reach orbit. With Saturday's success, Isar is the clear leader among a pack of several European launch startups vying to inject some competition into Europe's stagnant launch market.

Isar's 92-foot-tall (28-meter) Spectrum rocket lifted off at 4:12 pm EST (20:12 UTC) Saturday from Andøya Spaceport in northern Norway, where it was 10:12 pm local time and the final bluish hues of daylight faded from the late summer sky. Seven minutes later, the rocket was in orbit.

One week ago, more than 200 miles above the Earth, a refrigerator-size satellite making its way toward an attempted rescue of NASA's $500 million Swift gamma-ray observatory suddenly spun out of control.

It didn't look good. The spacecraft, named Link, was rotating on multiple axes, rendering it unable to maintain a reliable communications link with the ground and complicating efforts to arrest the spin. Two of the satellite's three reaction wheels, used for pointing, also stopped working. Through sporadic radio contact, engineers discovered a problem with some of the spacecraft's cold gas thrusters used for finer attitude control.

The Link satellite is built, owned, and operated by Katalyst Space Technologies, a satellite servicing startup that won a $30 million contract from NASA to fly up to the Swift observatory, grab onto it, and boost its orbit before succumbing to aerodynamic drag and burning up int he atmosphere.

A fast-moving wildfire, one of many raging across Spain, bore down on the Madrid Deep Space Communications Complex on Friday, forcing an evacuation and temporarily suspending operations at one of NASA's most important tracking stations.

The tracking station is part of NASA's Deep Space Network, operating in concert with similar facilities in California and Australia to provide global coverage as Earth's rotation brings the planets, stars, and deep space probes in and out of view. The network supports more than 40 missions from the Moon to the edge of the Solar System, including Artemis, the James Webb Space Telescope, and NASA's twin Voyager spacecraft.

A NASA spokesperson confirmed the tracking station in Spain, located in the hills nearly 40 miles (65 kilometers) west of central Madrid, was evaluated Friday "due to ongoing wildfires in the region. Photos and video from the area showed flames and smoke plumes rising over the ground station's antenna array, anchored by a 230-foot-diameter (70-meter) radio dish and a collection of smaller 112-foot (34-meter) antennas.

A spacecraft fitted with two flexible robotic arms is on the way to geosynchronous orbit after launching earlier this week on a SpaceX Falcon 9 rocket, kicking off a planned decade-long mission to open new frontiers in satellite servicing.

The Mission Robotic Vehicle, owned and built by Northrop Grumman, rocketed into orbit from Cape Canaveral Space Force Station in Florida on Tuesday. Three small propulsion pods, each functioning as standalone spacecraft, accompanied the MRV aboard the Falcon 9 rocket.

The Falcon 9 deployed all four payloads within about an hour of liftoff. It will take about a year for the satellites to maneuver from their initial elliptical drop-off orbit into a circular orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator. At this altitude, the MRV and the three Mission Extension Pods (MEPs) will travel in lockstep with Earth's rotation, operating in the same kind of orbit as numerous civilian and military communications satellites, missile warning platforms, and a growing number of spy satellites.

Welcome to Edition 9.04 of the Rocket Report! We've had to wait an extra week for SpaceX to get its 13th Starship test flight off the ground. A last-second abort on July 16 led engineers to roll the booster back to its hangar in South Texas to swap out engines. Starship is now back on the launch pad. Liftoff is set for Friday evening. A flawless launch and reentry will put SpaceX on the cusp of an orbital flight later this year. Ars will have a comprehensive recap story after the completion of the test flight.

India's first private rocket reaches orbit. Indian space officials celebrated the debut flight of Skyroot Aerospace’s Vikram-1 rocket, India’s first fully commercial satellite launcher, as a “grand success” Saturday after an on-target climb into a 280-mile-high orbit following liftoff from an island spaceport in the Bay of Bengal, Ars reports. The Vikram-1 lifted off from India’s primary spaceport on Sriharikota Island around midday local time. The launch was delayed more than a half-hour to resolve a last-minute technical problem. The countdown resumed, culminating in the command to ignite Vikram-1’s solid-fueled first stage booster to propel the rocket off the launch pad.

The Space Development Agency was established in 2019 to help speed up the deployment of US military space systems by sidestepping the Pentagon's traditional sluggish bureaucracy.

Seven years later, SDA is finally launching its first batches of operational satellites, just as the Pentagon plans to shutter the semi-autonomous agency and fold it back into the Space Force's procurement pipeline, newly reorganized under several program acquisition executives in a bid to streamline weapons buying.

SDA's fate is not a surprise, and lawmakers in both houses of Congress have backed the agency's closure in drafts of this year's National Defense Authorization Act.

SpaceX called off a test flight of its powerful Starship rocket and Super Heavy booster as the countdown clock reached zero Thursday at the company's spaceport in South Texas.

The launch team at Starbase, Texas, just north of the US-Mexico border, aimed to launch the more than 400-foot-tall rocket at 5:45 pm local time (6:45 pm EDT; 22:45 UTC). The countdown proceeded smoothly throughout the day, culminating in the loading of more than 11.5 million pounds of liquid methane and liquid oxygen into the two-stage rocket.

But the computers controlling the countdown called an abort during the Super Heavy booster's engine startup sequence. SpaceX scrubbed the launch attempt, and engineers began preparations to drain the rocket's propellant tanks. Officials did not immediately announce when they plan to try to launch again.

A SpaceX Falcon 9 rocket lifted off on Tuesday to test a new reentry vehicle designed to deliver cargo anywhere in the world from low-Earth orbit.

The company developed the new saucer-shaped reentry pod, called Starfall, under a veil of secrecy. Its purpose is to support the "transport and delivery of goods through space," according to an environmental assessment published by the Federal Aviation Administration last month.

The first demonstration of the Starfall vehicle began at 6:53 am EDT (10:53 UTC) with liftoff aboard a Falcon 9 rocket from Cape Canaveral Space Force Station, Florida. At least one Starfall reentry pod rode to orbit on the Falcon 9, perhaps alongside another undisclosed payload. After circling the planet two times, the Falcon 9's upper stage was expected to release Starfall for atmospheric reentry, targeting a parachute-assisted splashdown in the Pacific Ocean around 800 miles west of California.

Welcome to Edition 8.46 of the Rocket Report! We don't mention Starship in the body of this week's report, so I'll give a brief update here. The next test flight of SpaceX's mega-rocket—Flight 13—could happen as soon as next month, according to Gwynne Shotwell, the company's president and chief operating officer, in a recent interview with CNBC. There's still a fair bit of work to go before Flight 13, so don't count on a launch next month just yet. What we do know, based on Shotwell's comments to CNBC, is the next Starship test flight will look a like like the previous one last month, with a suborbital flight path and a splashdown of the ship in the Indian Ocean. SpaceX is holding off on an orbital flight until at least the following launch, Flight 14, after the ship was unable to complete a critical engine restart in space on the last flight.

Isar test flight scrubbed again. Isar Aerospace still commands top position among a new generation of European rocket startups, but the company’s efforts to launch a critical test flight of its Spectrum rocket continue to encounter roadblocks, Ars reports. The latest delay came Monday, when Isar scrubbed a launch attempt after "detecting off nominal behavior in the vehicle’s fluid systems," according to a social media post. "The teams are analyzing the new data to isolate the root cause." Isar is flush with cash, having raised nearly $1 billion to date, but is still lacking in the critical currently of flight experience. The Spectrum rocket has flown just once to date, on a failed launch last year that lasted less than 30 seconds.

WALLOPS ISLAND, Virginia—Just 10 months ago, NASA asked three companies if they could do something nobody had done before. Could they build and launch a satellite to save a $500 million astronomy mission at risk of crashing back to Earth? What's more, could they do it in less than a year on a tight budget?

Katalyst Space Technologies, a startup founded in 2020, presented the most compelling solution. "They came back with a response that was technically and programmatically plausible, and then we were like, 'Yeah, let’s do it,'" said Shawn Domagal-Goldman, director of NASA's astrophysics division.

That was in August of last year. In September, NASA awarded Katalyst a $30 million contract to build, test, and launch a small satellite to chase down Swift and latch onto it with three robotic arms. Then, Katalyst's Link servicing spacecraft will boost Swift's orbit back to a safe operating altitude, allowing it to resume scientific observations. Easier said than done.
