Northrop Grumman’s upgraded Cygnus XL vehicle experienced an engine issue on Tuesday, delaying its arrival to the International Space Station until further notice. This is the first flight of the larger version of the company’s solar-powered spacecraft, which is carrying 11,000 pounds of science investigations, food, supplies, and equipment to the space station’s crew. The cargo ship launched on Sunday at 6:11 p.m. ET on board a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station in

Experimental Spacecraft Headed to Space Station Suddenly Shuts Down

Lost in space. A whopping 11,000 pounds of supplies and scientific instruments that were headed to the International Space Station are in limbo after a high-profile malfunction. Northrop Grumman's Cygnus XL spacecraft encountered a serious problem with its main engine during its maiden voyage, NASA announced on Tuesday. The spacecraft, which is just over five feet longer than the aerospace giant's Cygnus spacecraft, launched from the Cape Canaveral Space Force Station in Florida on Sunday eve

Biggest Cygnus Cargo Ship Delayed on Its Way to the ISS Due to Engine Shutdown

A record supply load won’t reach the International Space Station as scheduled

A problem with the main engine on Northrop Grumman's Cygnus XL spacecraft will keep it from delivering 11,000 pounds of supplies and experiments to the International Space Station as scheduled on Wednesday. In a statement released Tuesday afternoon, NASA said ground teams are evaluating backup plans that might still allow the Cygnus spacecraft to reach the space station, just not on schedule. The problem arose early Tuesday when the spacecraft's main engine shut down earlier than expected durin

Northrop Grumman’s new spacecraft is a real chonker

What happens when you use a SpaceX Falcon 9 rocket to launch Northrop Grumman's Cygnus supply ship? A record-setting resupply mission to the International Space Station. The first flight of Northrop's upgraded Cygnus spacecraft, called Cygnus XL, is on its way to the international research lab after launching Sunday evening from Cape Canaveral Space Force Station, Florida. This mission, known as NG-23, is set to arrive at the ISS early Wednesday with 10,827 pounds (4,911 kilograms) of cargo to

Scientists Pinpoint Cause of Mysterious Electrical Surges on Satellites

In 1994, two Canadian TV satellites failed within mere hours of each other. The pair was in a geostationary orbit when a major solar storm hit, resulting in electrostatic discharges that disabled their control electronics. Anik E1 and E2 are just one example of the effects of electric charge buildup on satellites, known as spacecraft environment discharge. New findings show a direct correlation between a spacecraft’s electric discharge and peaks in the flux of electrons in space, identifying hu

Russian space official: “We need to stop lying to ourselves” about health of industry

The chief of Russia's main spacecraft manufacturer issued a dire warning this week, saying that his corporation has reached a "critical" condition and cannot continue in its present state. "The situation is critical: multi-million dollar debts, interest on loans that 'eat up' the budget, many processes that are ineffective, and a significant part of the team has lost motivation and a sense of shared responsibility," wrote Igor Maltsev, chief of RSC Energia, which is located near Moscow.

Part of Starship Explodes During SpaceX's Latest Test Flight

Coming off a string of explosive failures, on Tuesday night SpaceX once again launched its gigantic Starship rocket into space, with both its stages successfully returning to their separate landing targets on Earth. This time, the only huge explosions were planned one: final blasts as the two spacecraft touched down. After the launch had been scrubbed twice over the two prior days, the company's engineers could finally breathe a sigh of relief. The flight demonstrated several key objectives, i

Russia’s state-run human spaceflight company may be near bankruptcy

Last-Minute Software Patch Saves Jupiter Probe Ahead of Critical Venus Flyby

An exceptionally heavy interplanetary probe is on an eight-year journey to Jupiter, using the gravity of Earth and Venus to propel it on its path toward the gas giant. Just weeks before its scheduled flyby of Venus, the European Space Agency’s JUICE mission went silent, threatening its ability to perform the planetary encounter. Unable to communicate with the spacecraft, teams of engineers got to work on figuring out the problem under a tight schedule, hoping their efforts would reach JUICE as

NASA's Juno mission leaves legacy of science at Jupiter

The NASA spacecraft tasked with uncovering the secrets of Jupiter, king of the planets, is running out of time. The Juno probe has already survived far longer than anticipated—its path around the solar system’s largest planet has repeatedly flown it through a tempest of radiation that should have corroded away its instruments and electronics long ago. And yet here it is: one of the greatest planetary detectives ever built, still pirouetting around Jupiter, fully functional. But it may not be fo

Project Hyperion: Interstellar ship design competition

Project Hyperion explores the feasibility of crewed interstellar travel via generation ships, using current and near-future technologies. A generation ship is a hypothetical spacecraft designed for long-duration interstellar travel, where the journey may take centuries to complete. The idea behind a generation ship is that the initial crew would live, reproduce, and die on the ship, with their descendants continuing the journey until reaching the destination. These ships are often envisioned as

The ‘Hail Mary’ That Saved NASA’s Juno Camera From Jupiter’s Radiation Hell

NASA’s Juno spacecraft, which launched in 2011 to investigate Jupiter’s origin and evolution, travels through the solar system’s most intense planetary radiation fields. When the spacecraft’s JunoCam—a color, visible-light camera—began to suffer the consequences in December 2023, the mission team back on Earth had to think of a remote fix before they lost their chance to photograph the Jovian moon, Io. A relatively simple process was ultimately what enabled the long-distance save: heating the i

Astronomers Detect Entirely New Type of Plasma Wave Above Jupiter’s North Pole

Since entering Jupiter’s orbit in 2016, NASA’s Juno spacecraft has been hard at work unveiling the many mysteries of our solar system’s largest planet. And its latest discovery may be one of the most intriguing yet: an entirely new type of plasma wave near Jupiter’s poles. In a paper published Wednesday in Physical Review Letters, astronomers describe an unusual pattern of plasma waves in Jupiter’s magnetosphere—a magnetic “bubble” shielding the planet from external radiation. Jupiter’s excepti

If You Thought Your Life Was a Mess, Spare a Thought for Boeing's Massively Failed Starliner Spacecraft

Even after pouring $2 billion into its much-maligned Starliner spacecraft, NASA and Boeing remain committed to getting back off the ground. As Ars Technica reports, the head of NASA's commercial crew program, Steve Stich, revealed last week that Boeing and its propulsion supplier, Aerojet Rocketdyne, are making considerable changes to the astronaut shuttle following a disastrous first crewed mission to the International Space Station last year. The spacecraft experienced several "in-flight ano

After a partly successful test flight, European firm eyes space station mission

Last month, the parachutes on Hélène Huby's small spacecraft failed to deploy, and the vehicle and its cargo crashed into the ocean on Earth. It was both a success and a failure. The success was that after Huby founded The Exploration Company in Europe, she managed to move nimbly with the "Mission Possible" spacecraft such that it cost less than $25 million to build and reached space in less than three years. The vehicle ticked off a number of successes in spaceflight before making a controlle

Boeing’s Starliner Won’t Get to Fly This Year, but the Wonky Spacecraft Is Far From Dead

It’s been more than a year since Starliner’s failed test flight left a crew stranded in space, and Boeing’s spacecraft still isn’t ready to fly. In a recent update, NASA officials said they are working toward launching a mission aboard Starliner in 2026, and there probably won’t be any astronauts involved. During a press briefing last week, Steve Stich, NASA’s commercial crew program manager, told reporters that Boeing is making several changes to its Starliner spacecraft to keep its thrusters

The ISS is nearing retirement, so why is NASA still gung-ho about Starliner?

After so many delays, difficulties, and disappointments, you might be inclined to think that NASA wants to wash its hands of Boeing's troubled Starliner spacecraft. But that's not the case. The manager of NASA's commercial crew program, Steve Stich, told reporters Thursday that Boeing and its propulsion supplier, Aerojet Rocketdyne, are moving forward with several changes to the Starliner spacecraft to resolve problems that bedeviled a test flight to the International Space Station (ISS) last

Remember That Asteroid NASA Deflected in a Test of Saving Earth? We Have Bad News

In late 2022, NASA celebrated its Double Asteroid Redirection Test (DART) as a massive success, a proof of concept for saving humanity in case a similar space rock were to ever head straight for Earth. The small spacecraft smashed into asteroid Didymos' moonlet Dimorphos at a violent 14,000 mph, knocking it severely off course. But three years later, astronomers found that the collision had some unintended consequences. As detailed in a paper published last week in the Planetary Science Journa

With Varda Space, leading Silicon Valley players make big bet on making drugs in space

Pharmaceutical scientists come up against a hard limitations here on Earth: gravity. Varda Space wants to change that. The company has raised a massive new round to turn space into the “ultimate high ground” for the production of critical pharmaceutical components that can be brought back to Earth and used to make finished drugs. The company’s $187 million Series C funding round announced Thursday will be used to build out a new laboratory facility that could transform Varda’s orbital manufact

Investors appear to like a company with big space manufacturing ambitions

After flying three missions into low-Earth orbit this year, Varda Space Industries appears to be making credible progress toward developing the nascent manufacturing-in-space industry. Investors seem to think the same, as the California-based company announced an impressive $187 million Series C round of funding on Thursday. This brings the company's total amount of money raised since its founding in 2021 to $325 million. "A decent chunk of the capital is going to go toward scaling up our prod

After successfully entering Earth's atmosphere, a European spacecraft is lost

A European company that seeks to develop orbital spacecraft for cargo, and eventually humans, took a step forward this week with a test flight that saw its "Mission Possible" vehicle power up and fly successfully in orbit before making a controlled reentry into Earth's atmosphere. However, after encountering an "issue," the Exploration Company lost contact with its spacecraft a few minutes before touchdown in the ocean. In an update on LinkedIn Tuesday morning, the company characterized the te

Alert: There's a Lost Spaceship in the Ocean

It's lost forever? Dive Mind In science fiction, we often have the trope of a spacecraft becoming lost in space — but what about being lost at sea? That's what happened this week with an eight-foot-wide experimental spacecraft flown by a European aerospace outfit called The Exploration Company, according to a company statement on LinkedIn. When the vehicle came back to Earth, mission control lost contact with the craft when it entered the ocean. "The capsule was launched successfully, powere

SpaceX's String of Starship Failures Continues With Massive Rocket Explosion

SpaceX's ongoing mission to prepare Starship spacecraft for trips to the moon and, eventually, Mars suffered a setback when a spacecraft exploded this week in South Texas. The explosion happened during what SpaceX called routine testing in preparation for Starship's 10th flight since 2023, which was expected to happen later this month. SpaceX uses a different rocket design to launch its Starlink internet satellites. On X, the space company wrote, "On Wednesday, June 18 at approximately 11 p.m

The Mysterious Inner Workings of Io, Jupiter’s Volcanic Moon

The original version of this story appeared in Quanta Magazine. Scott Bolton’s first encounter with Io took place in the summer of 1980, right after he graduated from college and started a job at NASA. The Voyager 1 spacecraft had flown past this moon of Jupiter, catching the first glimpse of active volcanism on a world other than Earth. Umbrella-shaped outbursts of magmatic matter rocketed into space from all over Io’s surface. “They looked amazingly beautiful,” said Bolton, who is now based a
