While ULA studies Vulcan booster anomaly, it’s also investigating fairing issues

30 October 2024 at 15:13

A little more than a year ago, a snippet of video that wasn't supposed to go public made its way onto United Launch Alliance's live broadcast of an Atlas V rocket launch carrying three classified surveillance satellites for the US Space Force and the National Reconnaissance Office.

On these types of secretive national security missions, the government typically requests that the launch provider stop providing updates on the ascent into space when the rocket jettisons its two-piece payload fairing a few minutes after launch. And there should be no live video from the rocket released to the public showing the fairing separation sequence, which exposes the payloads to the space environment for the first time.

But the public saw video of the clamshell-like payload fairing falling away from the Atlas V rocket as it fired downrange from Cape Canaveral, Florida, on September 10, 2023. It wasn't pretty. Numerous chunks of material, possibly insulation from the inner wall of the payload shroud's two shells, fell off the fairing. The video embedded below shows the moment of payload fairing jettison.

For some reason, NASA is treating Orion’s heat shield problems as a secret

29 October 2024 at 01:44

For those who follow NASA's human spaceflight program, when the Orion spacecraft's heat shield cracked and chipped away during atmospheric reentry on the unpiloted Artemis I test flight in late 2022, what caused it became a burning question.

Multiple NASA officials said Monday they now know the answer, but they're not telling. Instead, agency officials want to wait until more reviews are done to determine what this means for Artemis II, the Orion spacecraft's first crew mission around the Moon, officially scheduled for launch in September 2025.

"We have gotten to a root cause," said Lakiesha Hawkins, assistant deputy associate administrator for NASA's Moon to Mars program office, in response to a question from Ars on Monday at the Wernher von Braun Space Exploration Symposium in Huntsville, Alabama.

Astronaut released from hospital after β€œmedical issue” upon return from space

25 October 2024 at 23:02

NASA said Saturday that an astronaut who was hospitalized after returning from space the day before has been released and is in "good health." The agency did not provide any more details on the matter, citing medical privacy protections.

The astronaut was one of four crew members who returned from a 235-day mission in low-Earth orbit with a predawn splashdown Friday. The four-person crew splashed down inside SpaceX's Crew Dragon Endeavour spacecraft at 3:29 am EDT (07:29 UTC) in the Gulf of Mexico south of Pensacola, Florida.

Commander Matthew Dominick, pilot Michael Barratt, mission specialist Jeanette Epps, and Russian cosmonaut Alexander Grebenkin were inside SpaceX's Dragon spacecraft for reentry and splashdown. NASA said one of its astronauts "experienced a medical issue" after the splashdown, and all four crew members were flown to Ascension Sacred Heart Pensacola for medical evaluation.

Rocket Report: Sneak peek at the business end of New Glenn; France to fly FROG

25 October 2024 at 11:00

Welcome to Edition 7.17 of the Rocket Report! Next week marks 10 years since one of the more spectacular launch failures of this century. On October 28, 2014, an Antares rocket, then operated by Orbital Sciences, suffered an engine failure six seconds after liftoff from Virginia and crashed back onto the pad in a fiery twilight explosion. I was there and won't forget seeing the rocket falter just above the pad, being shaken by the deafening blast, and then running for cover. The Antares rocket is often an afterthought in the space industry, but it has an interesting backstory touching on international geopolitics, space history, and novel engineering. Now, Northrop Grumman and Firefly Aerospace are developing a new version of Antares.

Boeing is still bleeding money on the Starliner commercial crew program

24 October 2024 at 21:58

Sometimes, it's worth noting when something goes unsaid.

On Wednesday, Boeing's new CEO, Kelly Ortberg, participated in his first quarterly conference call with investment analysts. Under fire from labor groups and regulators, Boeing logged a nearly $6.2 billion loss for the last three months, while the new boss pledged a turnaround for the troubled aerospace company.

What Ortberg didn't mention in the call was the Starliner program. Starliner is a relatively small portion of Boeing's overall business, but it's a high-profile and unprofitable one.

After nozzle failure, Space Force is β€œassessing” impacts to Vulcan schedule

23 October 2024 at 01:29

United Launch Alliance has started assembling its next Vulcan rocketβ€”the first destined to launch a US military payloadβ€”as the Space Force prepares to certify it to loft the Pentagon's most precious national security satellites.

Space Force officials expect to approve ULA's Vulcan rocket for military missions without requiring another test flight, despite an unusual problem on the rocket's second demonstration flight earlier this month.

ULA has launched two Vulcan test flights. Military officials watched closely, gathering data to formally certify the rocket is reliable enough to launch national security missions. The first test flight in January, designated Cert-1, was nearly flawless. The Cert-2 launch October 4 overcame an anomaly on one of Vulcan's strap-on solid rocket boosters, which lost its exhaust nozzle but kept firing with degraded thrust.

After seeing hundreds of launches, SpaceX’s rocket catch was a new thrill

21 October 2024 at 22:44

BOCA CHICA BEACH, Texasβ€”I've taken some time to process what happened on the mudflats of South Texas a little more than a week ago and relived the scene in my mind countless times.

With each replay, it's still as astonishing as it was when I saw it on October 13, standing on an elevated platform less than 4 miles away. It was surreal watching SpaceX's enormous 20-story-tall Super Heavy rocket booster plummeting through the sky before being caught back at its launch pad by giant mechanical arms.

This is the way, according to SpaceX, to enable a future where it's possible to rapidly reuse rockets, not too different from the way airlines turn around their planes between flights. This is required for SpaceX to accomplish the company's mission, set out by Elon Musk two decades ago, of building a settlement on Mars.

SpaceX prevails over ULA, wins military launch contracts worth $733 million

18 October 2024 at 23:23

The US Space Force's Space Systems Command announced Friday it has ordered nine launches from SpaceX in the first batch of dozens of missions the military will buy in a new phase of competition for lucrative national security launch contracts.

The nine launches are divided into two fixed-price "task orders" that Space Systems Command opened up for bids earlier this year. One covers seven launches with groups of spacecraft for the Space Development Agency's constellation of missile tracking and data relay satellites. The other task order is for two missions for the National Reconnaissance Office, the US government's spy satellite agency.

Two eligible bidders

The parameters of the competition limited the bidders to SpaceX and United Launch Alliance (ULA). SpaceX won both task orders for a combined value of $733.5 million, or roughly $81.5 million per mission. Six of the nine missions will launch from Vandenberg Space Force Base, California, beginning as soon as late 2025. The other three will launch from Cape Canaveral Space Force Station, Florida, a Space Systems Command spokesperson told Ars.

Biden administration curtails controls on some space-related exports

18 October 2024 at 00:25

The US Commerce Department announced Thursday it is easing restrictions on exports of space-related technology, answering a yearslong call from space companies to reform regulations governing international trade.

This is the most significant update to space-related export regulations in a decade and opens more opportunities for US companies to sell their satellite hardware abroad.

β€œWe are very excited about this rollout," a senior Commerce official said during a background call with reporters. "It’s been a long time coming, and I think it’s going to be very meaningful for our national security and foreign policy interests and certainly facilitate secure trade with our partners."

ULA is examining debris recovered from Vulcan rocket’s shattered booster nozzle

17 October 2024 at 13:55

When the exhaust nozzle on one of the Vulcan rocket's strap-on boosters failed shortly after liftoff earlier this month, it scattered debris across the beachfront landscape just east of the launch pad on Florida's Space Coast.

United Launch Alliance, the company that builds and launches the Vulcan rocket, is investigating the cause of the booster anomaly before resuming Vulcan flights. Despite the nozzle failure, the rocket continued its climb and ended up reaching its planned trajectory heading into deep space.

The nozzle fell off one of Vulcan's two solid rocket boosters around 37 seconds after taking off from Cape Canaveral Space Force Station on October 4. There were some indications of a problem with the booster a few seconds earlier, as tracking cameras observed hot exhaust escaping just above the bell-shaped nozzle, which is bolted to the bottom of the booster casing.

NASA launches mission to explore the frozen frontier of Jupiter’s moon Europa

15 October 2024 at 02:25

NASA's Europa Clipper spacecraft lifted off Monday from Kennedy Space Center in Florida aboard a SpaceX Falcon Heavy rocket, kicking off a $5.2 billion robotic mission to explore one of the most promising locations in the Solar System for finding extraterrestrial life.

The Falcon Heavy rocket fired its 27 kerosene-fueled engines and vaulted away from Launch Complex 39A at 12:06 pm EDT (16:06 UTC) Monday. Delayed several days due to Hurricane Milton, which passed through Central Florida late last week, the launch of Europa Clipper signaled the start of a five-and-a-half- year journey to Jupiter, where the spacecraft will settle into an orbit taking it repeatedly by one of the giant planet's numerous moons.

The moon of Jupiter that has most captured scientists' interest, Europa, is sheathed in ice. There's strong evidence of a global ocean of liquid water below Europa's frozen crust, and Europa Clipper is going there to determine if it has the ingredients for life.

SpaceX catches returning rocket in mid-air, turning a fanciful idea into reality

14 October 2024 at 00:14

BOCA CHICA BEACH, Texasβ€”SpaceX accomplished a groundbreaking engineering feat Sunday when it launched the fifth test flight of its gigantic Starship rocket and then caught the booster back at the launch pad in Texas with mechanical arms seven minutes later.

This achievement is the first of its kind, and it's crucial for SpaceX's vision of rapidly reusing the Starship rocket, enabling human expeditions to the Moon and Mars, routine access to space for mind-bogglingly massive payloads, and novel capabilities that no other companyβ€”or countryβ€”seems close to attaining.

The test flight began with a thundering liftoff of the 398-foot-tall (121.3-meter) Starship rocket at 7:25 am CDT (12:25 UTC) from SpaceX's Starbase launch site in South Texas, a few miles north of the US-Mexico border. The rocket's Super Heavy booster stage fired 33 Raptor engines, generating nearly 17 million pounds of thrust and gulping 20 tons of methane and liquid oxygen propellants per second at full throttle.

Starship is about to launch on its fifth flight, and this time there’s a catch

13 October 2024 at 07:49

Early Sunday morning, SpaceX will try something no one has ever done before. If all goes according to plan, around seven minutes after lifting off from South Texas, the huge stainless steel booster from SpaceX's Starship rocket will come back to the launch pad and slow to a hover, allowing powerful mechanical arms to capture it in midair.

This is SpaceX's approach to recovering Starship's Super Heavy booster. If it works, this method will make it easier and faster to reuse the rocket than it is to recycle boosters from SpaceX's smaller Falcon 9 launch vehicle. Falcon 9's boosters usually come down on a floating drone ship stationed hundreds of miles out to sea, requiring SpaceX to return the rocket to shore for refurbishment.

β€œWe’re going for high reusability," said Bill Gerstenmaier, SpaceX's vice president of build and flight reliability.

Rocket Report: ULA investigating SRB anomaly; Europa Clipper is ready to fly

11 October 2024 at 11:00

Welcome to Edition 7.15 of the Rocket Report! It's a big week for big rockets, with SpaceX potentially launching its next Starship test flight and a Falcon Heavy rocket with NASA's Europa Clipper mission this weekend. And a week ago, United Launch Alliance flew its second Vulcan rocket, which lost one of its booster nozzles in midair and amazingly kept going to achieve a successful mission. Are you not entertained?

Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

PLD Space is aiming high. Spanish launch provider PLD Space has revealed a family of new rockets that it plans to introduce beyond its Miura 5 rocket, which is expected to make its inaugural flight in 2025, European Spaceflight reports. The company also revealed that it was working on a crew capsule called Lince (Spanish for Lynx). PLD Space introduced its Miura Next, Miura Next Heavy, and Miura Next Super Heavy launch vehicles, designed in single stick, triple core, and quintuple core configurations with reusable boosters. At the high end of the rocket family's performance, the Miura Next Super Heavy could deliver up to 53 metric tons (nearly 117,000 pounds) of payload to low-Earth orbit. The Lince capsule could become Europe's first human-rated crew transportation spacecraft.

In a rare disclosure, the Pentagon provides an update on the X-37B spaceplane

10 October 2024 at 22:07

After more than nine months in an unusual, highly elliptical orbit, the US military's X-37B spaceplane will soon begin dipping its wings into Earth's atmosphere to lower its altitude before eventually coming back to Earth for a runway landing, the Space Force said Thursday.

The aerobraking maneuvers will use a series of passes through the uppermost fringes of the atmosphere to gradually reduce its speed with aerodynamic drag while expending minimal fuel. In orbital mechanics, this reduction in velocity will bring the apogee, or high point, of the X-37B's orbit closer to Earth.

Bleeding energy

The Space Force called the aerobraking a "novel space maneuver" and said its purpose was to allow the X-37B to "safely dispose of its service module components in accordance with recognized standards for space debris mitigation."

SpaceX’s next Starship launchβ€”and first catchβ€”could happen this weekend

8 October 2024 at 19:22

We may not have to wait as long as we thought for the next test flight of SpaceX's Starship rocket.

The world's most powerful launcher could fly again as soon as Sunday, SpaceX says, assuming the Federal Aviation Administration grants approval. The last public statement released from the FAA suggested the agency didn't expect to determine whether to approve a commercial launch license for SpaceX's next Starship test flight before late November.

There's some optimism at SpaceX that the FAA might issue a launch license much sooner, perhaps in time for Starship to fly this weekend. The launch window Sunday opens at 7 am CDT (8 am EDT; 12:00 UTC), about a half-hour before sunrise at SpaceX's Starbase launch site in South Texas.

SpaceX launches Europe’s Hera asteroid mission ahead of Hurricane Milton

7 October 2024 at 21:08

Two years ago, a NASA spacecraft smashed into a small asteroid millions of miles from Earth to test a technique that could one day prove useful to deflect an object off a collision course with Earth. The European Space Agency launched a follow-up mission Monday to go back to the crash site and see the damage done.

The nearly $400 million (363 million euro) Hera mission, named for the Greek goddess of marriage, will investigate the aftermath of a cosmic collision between NASA's DART spacecraft and the skyscraper-size asteroid Dimorphos on September 26, 2022. NASA's Double Asteroid Redirection Test mission was the first planetary defense experiment, and it worked, successfully nudging Dimorphos off its regular orbit around a larger companion asteroid named Didymos.

But NASA had to sacrifice the DART spacecraft in the deflection experiment. Its destruction meant there were no detailed images of the condition of the target asteroid after the impact. A small Italian CubeSat deployed by DART as it approached Dimorphos captured fuzzy long-range views of the collision, but Hera will perform a comprehensive survey when it arrives in late 2026.

ULA’s second Vulcan rocket lost part of its booster and kept going

4 October 2024 at 20:08

United Launch Alliance's Vulcan rocket, under contract for dozens of flights for the US military and Amazon's Kuiper broadband network, lifted off from Florida on its second test flight Friday, suffered an anomaly with one of its strap-on boosters, and still achieved a successful mission, the company said in a statement.

This test flight, known as Cert-2, is the second certification mission for the new Vulcan rocket, a milestone that paves the way for the Space Force to clear ULA's new rocket to begin launching national security satellites in the coming months.

While ULA said the Vulcan rocket continued to hit its marks during the climb into orbit Friday, engineers are investigating what happened with one of its solid rocket boosters shortly after liftoff.

ULA hasn’t given up on developing a long-lived cryogenic space tug

3 October 2024 at 16:40

The second flight of United Launch Alliance's Vulcan rocket, planned for Friday morning, has a primary goal of validating the launcher's reliability for delivering critical US military satellites to orbit.

Tory Bruno, ULA's chief executive, told reporters Wednesday that he is "supremely confident" the Vulcan rocket will succeed in accomplishing that objective. The Vulcan's second test flight, known as Cert-2, follows a near-flawless debut launch of ULA's new rocket on January 8.

β€œAs I come up on Cert-2, I’m pretty darn confident I’m going to have a good day on Friday, knock on wood," Bruno said. "These are very powerful, complicated machines."
