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.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). 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.

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.

Anomaly resolution … This was the fifth flight of an Alpha rocket since 2021 and the fourth Alpha flight to achieve orbit. But the last Alpha launch in December failed to place its Lockheed Martin payload into the proper orbit due to a problem during the relighting of its second-stage engine. On this week’s launch, Alpha deployed its NASA-sponsored payloads after a single burn of the second stage, then completed a successful restart of the engine for a plane change maneuver. Engineers traced the problem on the last Alpha flight to a software error. (submitted by Ken the Bin)

Two companies added to DoD’s launch pool. Blue Origin and Stoke Space Technologies — neither of which has yet reached orbit — have been approved by the US Space Force to compete for future launches of small payloads, Breaking Defense reports. Blue Origin and Stoke Space join a roster of launch companies eligible to compete for launch task orders the Space Force puts up for bid through the Orbital Services Program-4 (OSP-4) contract. Under this contract, Space Systems Command buys launch services for payloads 400 pounds (180 kilograms) or greater, enabling launch from 12 to 24 months of the award of a task order. The OSP-4 contract has an “emphasis on small orbital launch capabilities and launch solutions for Tactically Responsive Space mission needs,” said Lt. Col. Steve Hendershot, chief of Space Systems Command’s small launch and targets division.

An even dozen … Blue Origin aims to launch its orbital-class New Glenn rocket for the first time as soon as late September, while Stoke Space aims to fly its Nova rocket on an orbital test flight next year. The addition of these two companies means there are 12 providers eligible to bid on OSP-4 task orders. The other companies are ABL Space Systems, Aevum, Astra, Firefly Aerospace, Northrop Grumman, Relativity Space, Rocket Lab, SpaceX, United Launch Alliance, and X-Bow.

Italian startup test-fires small rocket. Italian rocket builder Sidereus Space Dynamics has completed the first integrated system test of its EOS rocket, European Spaceflight reports. This test occurred Sunday, culminating in a firing of the rocket’s kerosene/liquid oxygen MR-5 main engine for approximately 11 seconds. The EOS rocket is a novel design, utilizing a single-stage-to-orbit architecture, with the reusable booster returning to Earth from orbit for recovery under a parafoil. The rocket stands less than 14 feet (4.2 meters) tall and will be capable of delivering about 29 pounds (13 kilograms) of payload to low-Earth orbit.

A lean operation … After it completes integrated testing on the ground, the company will conduct the first low-altitude EOS test flights. Founded in 2019, Sidereus has raised 6.6 million euros ($7.1 million) to fund the development of the EOS rocket. While this is a fraction of the funding other European launch startups like Isar Aerospace, MaiaSpace, and Orbex have attracted, the Sidereus’s CEO, Mattia Barbarossa, has previously stated that the company intends to “reshape spaceflight in a fraction of the time and with limited resources.” (submitted by EllPeaTea and Ken the Bin)

Chinese space firm unintentionally launches its new rocket

What goes up must come down —

Space Pioneer had been prepping the vehicle for its debut launch later this summer.

Space Pioneer

One of the most promising Chinese space startups, Space Pioneer, experienced a serious anomaly this weekend while testing the first stage of its Tianlong-3 rocket near the city of Gongyi.

The rocket was undergoing a static fire test of the stage, in which a vehicle is clamped to a test stand while its engines are ignited, when the booster broke free. According to a statement from the company, the rocket was not sufficiently clamped down and blasted off from the test stand “due to a structural failure.”

Video of the accidental ascent showed the rocket rising several hundred meters into the sky before it crashed explosively into a mountain 1.5 km away from the test site. (See various angles of the accident here, on the social media site X, or on Weibo.) The statement from Space Pioneer sought to downplay the incident, saying it had implemented safety measures before the test, and there were no casualties as a result of the accident. “The test site is far away from the urban area of ​​Gongyi,” the company said.

This is not entirely true, however. Located in the Henan province in eastern China, alongside the Yellow River, Gongyi has a population of about 800,000 people. The test stand is only about 5 km away from the city’s downtown and less than a kilometer from a smaller village.

Such accidents are rare in the launch industry but not unprecedented. Typically, during a static fire test, the mass of propellant on board a vehicle combined with strong clamps hold a rocket down. However, in 1952, a US Viking rocket broke loose of its moorings at White Sands Missile Range in New Mexico. It crashed 6 km downrange of the launch site without casualties.

How big of a setback?

It is unclear how big of a setback this will be for Space Pioneer, a quasi-private company founded in 2019. A little more than a year ago, Space Pioneer became the first Chinese company to reach orbit with a liquid-fueled rocket. It did so, impressively, on the first attempt of its small Tianlong-2 rocket. This was a notable achievement, but the rocket’s engines were provided by a Chinese state-operated firm, the Academy of Aerospace Liquid Propulsion Technology, rather than the private company.

For the larger Tianlong-3 rocket, Space Pioneer says it is manufacturing its own kerosene-fueled engines, known as TH-12. (They appear to have performed as expected this weekend.) Nine of these engines will power the Tianlong-3 rocket, which is intended to have a thrust of 17 tons to low-Earth orbit. The rocket’s design and the planned reuse of its first stage mimic the Falcon 9 rocket developed by SpaceX.

Space Pioneer had been prepping the vehicle for its debut launch later this summer or fall—and first-stage static-fire tests are indicative of a rocket’s final testing phase before liftoff. The company’s statement did not set a new timeline for a launch attempt but said it would complete the fault analysis “as soon as possible.”

China has the most vibrant commercial space industry in the world after the United States. Nearly a decade ago, the country’s leadership committed to sharing state-owned technology with companies that raised private funding, seeking to emulate the commercial success of SpaceX and other US companies.

Today, there are dozens of Chinese firms developing rockets, satellites, and other spaceflight products. Space Pioneer has been among the most promising, having raised more than $400 million since its inception five years ago.
