Welcome to Edition 7.07 of the Rocket Report! SpaceX has not missed a beat since the Federal Aviation Administration gave the company a green light to resume Falcon 9 launches after a failure last month. In 19 days, SpaceX has launched 10 flights of the Falcon 9 rocket, taking advantage of all three of its Falcon 9 launch pads. This is a remarkable cadence in its own right, but even though it's a small sample size, it is especially impressive right out of the gate after the rocket's grounding.

A quick turnaround for Rocket Lab. Rocket Lab launched its 52nd Electron rocket on August 11 from its private spaceport on Mahia Peninsula in New Zealand, Space News reports. The company's light-class Electron rocket deployed a small radar imaging satellite into a mid-inclination orbit for Capella Space. This was the shortest turnaround between two Rocket Lab missions from its primary launch base in New Zealand, coming less than nine days after an Electron rocket took off from the same pad with a radar imaging satellite for the Japanese company Synspective. Capella's Acadia 3 satellite was originally supposed to launch in July, but Capella requested a delay to perform more testing of its spacecraft. Rocket Lab swapped its place in the Electron launch sequence and launched the Synspective mission first.

Welcome to Edition 7.05 of the Rocket Report! The Federal Aviation Administration grounded SpaceX's Falcon 9 rocket for 15 days after a rare failure of its upper stage earlier this month. The FAA gave the green light for Falcon 9 to return to flight July 25, and within a couple of days, SpaceX successfully launched three missions from three launch pads. There's a lot on Falcon 9's to-do list, so we expect SpaceX to quickly return to form with several flights per week.

Big delay for a reusable rocket testbed. The French space agency, CNES, has revealed that the inaugural test flight of its Callisto reusable rocket demonstrator will not take place until late 2025 or early 2026, European Spaceflight reports. CNES unveiled an updated website for the Callisto rocket program earlier this month, showing the test rocket has been delayed from a debut launch later this year to until late 2025 or early 2026. The Callisto rocket is designed to test techniques and technologies required for reusable rockets, such as vertical takeoff and vertical landing, with suborbital flights from the Guiana Space Center in South America.

The emails from United Launch Alliance started popping into the inboxes of photographers a few days after the Fourth of July holiday. Although that day is meant to celebrate freedom and the red glare of rockets, the communication threatened to strip both from some of the company's most ardent devotees.

The message from the launch company announced the implementation of a new "annual agreement" between ULA and all people who place remote cameras at Space Launch Complex-41, the company's active launch site at Cape Canaveral Space Force Station. Anyone interested in setting remotes for future launch dates had 11 days to review and sign the agreement.

The language was clear: Photographers were welcome to set up remote shots at ULA launches if they worked for the media or wanted to post their work on social media. However, photographers could not sell this work independently, including as prints for fellow enthusiasts or for use in annual calendars.

United Launch Alliance delivered a classified US military payload to orbit Tuesday for the last time with an Atlas V rocket, ending the Pentagon's use of Russian rocket engines as national security missions transition to all-American launchers.

The Atlas V rocket lifted off from Cape Canaveral Space Force Station in Florida at 6:45 am EDT (10:45 UTC) Tuesday, propelled by a Russian-made RD-180 engine and five strap-on solid-fueled boosters in its most powerful configuration. This was the 101st launch of an Atlas V rocket since its debut in 2002, and the 58th and final Atlas V mission with a US national security payload since 2007.

The US Space Force's Space Systems Command confirmed a successful conclusion to the mission, code-named USSF-51, on Tuesday afternoon. The rocket's Centaur upper stage released the top secret USSF-51 payload about seven hours after liftoff, likely in a high-altitude geostationary orbit over the equator. The military did not publicize the exact specifications of the rocket's target orbit.

United Launch Alliance is targeting September 16 for the second test flight of the new Vulcan rocket, and a flawless mission could finally set the stage for the first Vulcan launch for the US military by the end of the year.

The US Space Force has contracted ULA's Vulcan rocket to launch the majority of the military's space missions over the next few years. Pentagon officials are eager for Vulcan to get flying so they can start checking off a backlog of 25 military space missions the Space Force wants to launch by the end of 2027.

By any measure, the first Vulcan launch in January was a resounding success. On its debut flight, the new rocket delivered a commercial lunar lander to an on-target orbit. The next Vulcan mission, which ULA calls Cert-2, will be the rocket's second certification flight. The Space Force requires ULA to complete two successful flights of the Vulcan rocket before entrusting it to launch national security satellites.

Welcome to Edition 7.01 of the Rocket Report! We're compiling this week's report a day later than usual due to the Independence Day holiday. Ars is beginning its seventh year publishing this weekly roundup of rocket news, and there's a lot of it this week despite the holiday here in the United States. Worldwide, there were 122 launches that flew into Earth orbit or beyond in the first half of 2024, up from 91 in the same period last year.

Firefly launches its fifth Alpha flight. Firefly Aerospace placed eight CubeSats into orbit on a mission funded by NASA on the first flight of the company’s Alpha rocket since an upper stage malfunction more than half a year ago, Space News reports. The two-stage Alpha rocket lifted off from Vandenberg Space Force Base in California late Wednesday, two days after an issue with ground equipment aborted liftoff just before engine ignition. The eight CubeSats come from NASA centers and universities for a range of educational, research, and technology demonstration missions. This was the fifth flight of Firefly's Alpha rocket, capable of placing about a metric ton of payload into low-Earth orbit.

United Launch Alliance and Blue Origin are worried about SpaceX's plans to launch its enormous Starship rocket from Florida.

In documents submitted to the Federal Aviation Administration last month, ULA and Blue Origin raised concerns about the impact of Starship launch operations on their own activities on Florida's Space Coast. Blue Origin, Jeff Bezos' space company, urged the federal government to consider capping the number of Starship launches and landings, test-firings, and other operations, and limiting SpaceX's activities to particular times.

Elon Musk, founder and CEO of SpaceX, called Blue Origin's filing with the FAA "an obviously disingenuous response. Not cool of them to try (for the third time) to impede SpaceX’s progress by lawfare." We'll get to that in a moment.

Welcome to Edition 6.50 of the Rocket Report! SpaceX launched its 10th Falcon Heavy rocket this week with the GOES-U weather satellite for NOAA, and this one was a beauty. The late afternoon timing of the launch and atmospheric conditions made for great photography. Falcon Heavy has become a trusted rocket for the US government, and its next flight in October will deploy NASA's Europa Clipper spacecraft on the way to explore one of Jupiter's enigmatic icy moons.

Sir Peter Beck dishes on launch business. Ars spoke with the recently knighted Peter Beck, founder and CEO of Rocket Lab, on where his scrappy company fits in a global launch marketplace dominated by SpaceX. Rocket Lab racked up the third-most number of orbital launches by any US launch company (it's headquartered in California but primarily assembles and launches rockets in New Zealand). SpaceX's rideshare launch business with the Falcon 9 rocket is putting immense pressure on small launch companies like Rocket Lab. However, Beck argues his Electron rocket is a bespoke solution for customers desiring to put their satellite in a specific place at a specific time, a luxury they can't count on with a SpaceX rideshare.

The second flight of United Launch Alliance's Vulcan rocket will take off in September with a dummy payload in place of Sierra Space's Dream Chaser spaceplane, preserving a chance for ULA to begin launching US military satellites on the new rocket by the end of the year, officials announced Wednesday.

Tory Bruno, ULA's CEO, announced the change in flight plan for the second Vulcan rocket in a conference call with reporters. There was little hope Sierra Space's Dream Chaser would be ready to make its first resupply run to the International Space Station before the end of the summer.

Dream Chaser had been booked to launch on the second test flight of ULA's Vulcan rocket for the last five years. With the near-flawless inaugural flight of Vulcan in January and a successful second flight later this year, ULA's Vulcan will be certified by the US Space Force to loft the military's most sensitive national security satellites into orbit.

After years of lobbying, protests, and bidding, Jeff Bezos's space company is now a military launch contractor.

The US Space Force announced Thursday that Blue Origin will compete with United Launch Alliance and SpaceX for at least 30 military launch contracts over the next five years. These launch contracts have a combined value of up to $5.6 billion.

This is the first of two major contract decisions the Space Force will make this year as the military seeks to foster more competition among its roster of launch providers and reduce its reliance on just one or two companies.

After years of delays, Boeing's Starliner spacecraft finally rocketed into orbit from Florida on Wednesday, sending two veteran NASA astronauts on a long-delayed shakedown cruise to the International Space Station.

The Starliner capsule lifted off at 10:52 am EDT (14:52 UTC) on top of a United Launch Alliance Atlas V rocket. Fifteen minutes later, after shedding two strap-on boosters and a core stage powered by a Russian RD-180 engine, the Atlas V's Centaur upper stage released Starliner right on target to begin a nearly 26-hour pursuit of the space station. Docking at the space station is set for 12:15 pm EDT (16:15 UTC) Thursday, where NASA astronauts Butch Wilmore and Suni Williams will spend at least a week before coming back to Earth.

In remarks shortly after Wednesday's launch, NASA Administrator Bill Nelson said Wilmore and Williams, both former US Navy pilots, will "test this thing from izzard to gizzard" to ensure Boeing's Starliner is ready for operational six-month crew rotation missions to the ISS.

Fresh off repairs at the launch pad in Florida, United Launch Alliance engineers restarted the countdown overnight for the third attempt to send an Atlas V rocket and Boeing's Starliner spacecraft on a test flight to the International Space Station.

NASA astronauts Butch Wilmore and Suni Williams were expected to awake early Wednesday, put on their blue pressure suits, and head to the launch pad at Cape Canaveral Space Force Station to board the Starliner capsule on top of the 172-foot-tall Atlas V rocket.

Once more through the door

Wilmore and Williams have done this twice before in hopes of launching into space on the first crew flight of Boeing's Starliner spacecraft. A faulty valve on the Atlas V rocket prevented liftoff May 6, then engineers discovered a helium leak on the Starliner capsule itself. After several weeks of troubleshooting, NASA and Boeing officials decided to proceed with another launch attempt Saturday.

A computer controlling the Atlas V rocket's countdown triggered an automatic hold less than four minutes prior to liftoff of Boeing's commercial Starliner spacecraft Saturday, keeping the crew test flight on the ground at least a few more days.

NASA astronauts Butch Wilmore and Suni Williams were already aboard the spacecraft when the countdown stopped due to a problem with a ground computer. "Hold. Hold. Hold," a member of Atlas V launch team called out on an audio feed.

With the hold, the mission missed an instantaneous launch opportunity at 12:25 pm EDT (16:25 UTC), and later Saturday, NASA announced teams will forego a launch opportunity Sunday. The next chance to send Starliner into orbit will be 10:52 am EDT (14:52 UTC) Wednesday. The mission has one launch opportunity every one-to-two days, when the International Space Station's orbital track moves back into proper alignment with the Atlas V rocket's launch pad in Florida.

NASA and Boeing officials are ready for a second attempt to launch the first crew test flight on the Starliner spacecraft Saturday from Cape Canaveral Space Force Station, Florida.

Liftoff of Boeing's Starliner, capsuled atop a United Launch Alliance Atlas V rocket, is set for 12:25 pm EDT (16:25 UTC). NASA commander Butch Wilmore and pilot Suni Williams, both veteran astronauts, will take the Starliner spacecraft on its first trip into low-Earth orbit with a crew on board.

Senior managers from NASA and Boeing told reporters on Friday that they plan to launch the first crew test flight of the Starliner spacecraft as soon as June 1, following several weeks of detailed analysis of a helium leak and a "design vulnerability" with the ship's propulsion system.

Extensive data reviews over the last two-and-a-half weeks settled on a likely cause of the leak, which officials described as small and stable. During these reviews, engineers also built confidence that even if the leak worsened, it would not add any unacceptable risk for the Starliner test flight to the International Space Station, officials said.

But engineers also found that an unlikely mix of technical failures in Starliner's propulsion system—representing 0.77 percent of all possible failure modes, according to Boeing's program manager—could prevent the spacecraft from conducting a deorbit burn at the end of the mission.
