A new rocket passed a key milestone with a successful test at Vandenberg Space Force Base this week en route to its maiden launch in two weeks.

Firefly Aerospace announced on Thursday that the firm had performed a static fire test of the Alpha launch vehicle, which stands 95 feet tall, at Space Launch Complex 2. 

“The fully-fueled, flight-ready vehicle fired its first stage engines for 15 seconds,” Firefly announced on Twitter.

A video posted online shows the static fire test with one crew member saying, “Burn, baby, burn.” Another crew member asked for the “plus count,” leading to someone else to report the tally “14, 15.”

“Made it all the way,” a crew member said, prompting applause from others audible in the background.

A static fire test involves counting down to zero and igniting the first stage engines while the rocket remains earthbound.

“The test was successful and clears the way for Firefly to make its first launch attempt, currently scheduled for Sept. 2,” the firm said.

The company did not release the intended launch time or any other details about the debut of the small rocket. Launch dates, especially for new rockets, can be fluid because of technical troubles requiring attention before liftoff or unfavorable weather.

Alpha's maiden flight will carry the Dedicated Research and Education Accelerator Mission, or DREAM, a collection of academic and educational payloads chosen after a global competition to find rideshare participants. More than two dozen DREAM payloads represent seven countries, according to Firefly's 2019 announcement.

For the past few months, there have been several false reports floating around social media about launch dates for this mission, although Firefly has said only that the team was working toward readying for the inaugural launch.

This week’s test came after an earlier attempt didn’t go as planned and it was aborted for what Firefly’s Eric Salwan, co-founder and director of commercial business development, called “a non-static, fire-related item."

“We reviewed the data and were satisfied that the launch site and launch vehicle are ready for the launch,” Salwan said in late June. 

The team also had to await the arrival a crucial component from a vendor related to the flight termination system undergoing qualification testing. 

In April, Firefly announced that the rocket had been raised from a horizontal position at the launch site.

“Today, on the 60th anniversary of man first reaching space, we fully installed Alpha and rotated vertical on Firefly’s Vandenberg launch pad,” the firm said. 

Firefly is using the former Delta II rocket launch pad, but the signature blue mobile service tower was removed by a contractor. That project sparked a fire, leading to dramatic pictures of flames and black smoke from the site last October.

This spring, Firefly also worked to line up additional financing and awarded a contract to Space Exploration Technologies to launch its Blue Ghost lunar lander in 2023. Blue Ghost will be carrying 10 payloads for NASA’s Commercial Lunar Payload Services (CLPS) mission.

Even as they work toward the first launch, the team has been building Alpha Flight 2 and 3 launch vehicles. The team expects to follow up with a second launch shortly after the first launch.

Based in Cedar Park, Texas, Firefly is developing a family of launch and in-space vehicles and services with a focus on affordability, convenience and reliability. Firefly’s rocket uses common technologies, manufacturing infrastructure and launch capabilities in providing rides to space for smaller payloads. 

Vandenberg expects to have a busy late summer with as many as four missions hoping to get off the ground in early September. That includes the United Launch AllianceAtlas V rocket carrying NASA’s Landsat 9 Earth-observing satellite.

Firefly Aerospace’s Alpha rocket ready for first launch

COLORADO SPRINGS — Firefly Aerospace is ready to make its first orbital launch attempt next week as the company balances a transition to operations with plans to develop new rockets and spacecraft.

Firefly announced Aug. 19 that it had set a Sept. 2 date for the first launch of its Alpha rocket from Vandenberg Space Force Base in California. The announcement came a day after the small launch vehicle performed a successful 15-second static fire test on the pad at Vandenberg.

In an interview during the 36th Space Symposium here Aug. 24, Tom Markusic, chief executive of Firefly, said the only milestone left before the scheduled launch is finalizing paperwork. “The static-fire test was perfect,” he said. “If we had let the rocket go it would have flown. All the data looks great.”

The company has extensively tested that rocket, including nearly 20 hot-fire tests. “This vehicle has definitely been put through its paces,” he said. “We’re ready to go.”

The rocket could have been ready sooner but for the delayed delivery of a component needed for its flight termination system. Markusic declined to identify the specific component or its supplier, but said it was one of the few major components that the company did not develop in-house.

“The vendor could not get the components qualified and delivered on time,” he said. “We’re a year behind schedule on that flight termination system.”

The inaugural Alpha launch will carry a payload called the Dedicated Research and Education Accelerator Mission (DREAM), a Firefly initiative to provide a free launch for academic and other private payloads. The launch will also test components of an orbital transfer vehicle the company is developing called the Space Utility Vehicle.

If the first launch is a success, Markusic said a second Alpha would be ready for launch as soon as December carrying a commercial payload. However, he acknowledged that the first launch of a new vehicle carries a higher risk of failure.

“It’s not unusual to have an anomaly on the first flight and then, just depending on the severity of the anomaly, it could be several weeks to several months” to correct the problem, he said. “Alpha is a pretty straightforward rocket design, so whatever problem we might have, we think it is something that can be addressed relatively quickly.”

A successful launch would create a different set of challenges, as Firefly moves from development to operations. “The transition from R&D to production is going to be very hard,” Markusic said.

Firefly announced Aug. 17 it hired a new chief operating officer, Lauren Lyons, who previously worked at SpaceX and Blue Origin. “She is going to focus on establishing the infrastructure and the capability to go to scale production while we still keep and grow that core hardware development capability for new vehicles,” he said. “You have to have both.”

Markusic said he will focus more on new vehicle development, including a medium-class launch vehicle called Beta as well as the Space Utility Vehicle and the Blue Ghost lunar lander. He said Firefly recently completed a conceptual design of Beta, which the company plans to develop over the next three years.

Firefly is also moving into the components business, starting with offering the engines it developed for Alpha to other customers. Markusic said Firefly has a contract to deliver about 50 engines to an unidentified company developing its own launch vehicle.

That’s a departure from the approach most companies have taken to be as vertically integrated as possible. “If you really want to get economies of scale, the more you can make, the better,” he said.

That components business will expand to other items, such as composite-overwrapped pressure vessels. “We have grander aspirations to have a large-scale e-commerce presence,” he said. “The dream is to point, click, and have a rocket engine the next day.”

Firefly’s Alpha rocket explodes on inaugural test launch

The first test flight of Firefly Aerospace’s privately-developed Alpha small satellite launcher ended in a fiery failure soon after liftoff Thursday from Vandenberg Space Force Base in California.

The rocket roared away from its pad at Space Launch Complex 2-West at 6:59 p.m. PDT (9:59 p.m. EDT; 0159 GMT) and all appeared to be going well as it climbed into a clear blue sky. The first sign of possible trouble came at about T+1 minute 47 seconds when a launch controller reported Alpha was not yet supersonic, a milestone it was supposed to have reached 40 seconds prior to that. At T+2 minutes 18 seconds the controller advised “vehicle is supersonic”. Shortly there after the rocket appeared to lose control and tumble for several seconds before exploding, approximately 2 minutes 29 seconds after launch.

Firefly Aerospace confirmed the mishap in a tweet: “Alpha experienced an anomaly during first stage ascent that resulted in the loss of the vehicle. As we gather more information, additional details will be provided.”

It was the inaugral flight for the two-stage Alpha rocket, which is designed to loft up to 2,200 pounds (1,000 kilograms) into a low-altitude orbit, or up to 1,388 pounds (630 kilograms) of payload to a 310-mile-high (500-kilometer) sun-synchronous polar orbit.

The kerosene-fueled rocket is one of many privately-developed small satellite launchers new to the market. It is powered by four Reaver engines on the first stage which generate more than 165,000 pounds of thrust at maximum power, and a Lightning engine on the second stage will produces more than 15,000 pounds of thrust.

Firefly says the size of its rocket — which can carry heavier payloads than Rocket Lab’s Electron or Virgin Orbit’s LauncherOne — differentiates it from other prospective launch providers in the smallsat launch market. It expects to sell a dedicated Alpha launch for $15 million per flight.

 

The fully-assembled Alpha launch vehicle stands around 97.6 feet (29.75 meters) tall and measures nearly 6 feet (1.8 meters) in diameter.

Firefly Aerospace, headquartered in Cedar Park, Texas, was previously named Firefly Space Systems before entering bankruptcy. The renamed company emerged from bankruptcy proceedings in 2017 under new ownership.

Noosphere Ventures, a Menlo Park, California-based firm led by managing partner Max Polyakov, now funds Firefly’s rocket development program.

Firefly’s other projects beyond the Alpha launcher include the Beta rocket, which will use upgraded engines to haul heavier payloads into orbit. Firefly also has ambitions for a robotic lunar lander, a space tug powered by electric thrusters, and a reusable spaceplane.

In addition to its pad at Vandenberg, Firefly is also developing a second launch site would be located at the disused Complex 20 launch pad at Cape Canaveral Space Force Station in Florida.

For this first test flight the rocket was carrying a suite of educational, artistic, and research payloads. The company offered free launch capacity through a program Firefly calls the Dedicated Research and Education Accelerator Mission, or DREAM.

The Alpha rocket was targeting a 186-mile-high inclined 137 degrees to the equator. The unusual orbit, called a retrograde orbit because the rocket will travel against the Earth’s rotation, required the Alpha launcher to head southwest over the Pacific Ocean on a track that would have taken it south of Hawaii.
