Honda’s hopper suddenly makes the Japanese carmaker a serious player in rocketry

The company has not disclosed its spending on rocket development. Honda’s hopper is smaller than similar prototype boosters SpaceX has used for vertical landing demos, so engineers will have to scale up the design to create a viable launch vehicle.

But Tuesday’s test catapulted Honda into an exclusive club of companies that have flown reusable rocket hoppers with an eye toward orbital flight, including SpaceX, Blue Origin, and a handful of Chinese startups. Meanwhile, European and Japanese space agencies have funded a pair of reusable rocket hoppers named Themis and Callisto. Neither rocket has ever flown, after delays of several years.

Honda’s experimental rocket lifts off from a test site in Taiki, a community in northern Japan.

Before Honda’s leadership green-lit the rocket project in 2019, a group of the company’s younger engineers proposed applying the company’s expertise in combustion and control technologies toward a launch vehicle. Honda officials believe the carmaker “has the potential to contribute more to people’s daily lives by launching satellites with its own rockets.”

The company suggested in its press release Tuesday that a Honda-built rocket might launch Earth observation satellites to monitor global warming and extreme weather, and satellite constellations for wide-area communications. Specifically, the company noted the importance of satellite communications to enabling connected features in cars, airplanes, and other Honda products.

“In this market environment, Honda has chosen to take on the technological challenge of developing reusable rockets by utilizing Honda technologies amassed in the development of various products and automated driving systems, based on a belief that reusable rockets will contribute to achieving sustainable transportation,” Honda said.

Toyota, Japan’s largest car company, also has a stake in the launch business. Interstellar Technologies, a Japanese space startup, announced a $44 million investment from Toyota in January. The two firms said they were establishing an alliance to draw on Toyota’s formula for automobile manufacturing to set up a factory for mass-producing orbital-class rockets. Interstellar has launched a handful of sounding rockets but hasn’t yet built an orbital launcher.

Japan’s primary rocket builder, Mitsubishi Heavy Industries, is another titan of Japanese industry, but it has never launched more than six space missions in a single year. MHI’s newest rocket, the H3, debuted in 2023 but is fully expendable.

The second-biggest Japanese automaker, Honda, is now making its own play. Car companies aren’t accustomed to making vehicles that can only be used once.

The Pentagon seems to be fed up with ULA’s rocket delays

Some of the displeasure was apparent in April when the US military announced that it would ask SpaceX to launch a plurality of its missions during the next round of national security launches, reversing the preeminent role that ULA had held for the last two decades.

ULA retired its Delta IV Heavy rocket in April 2024, and the handful of Atlas V rockets that remain are committed to other missions. This has left the Air Force dependent on SpaceX, with its Falcon 9 and Falcon Heavy vehicles, as the only provider of launch services to get its most expensive and highest priority satellites into orbit.

ULA must “repair trust”

In his testimony, Purdy said ULA completed certification of the initial variant of its Vulcan rocket for military launches from Cape Canaveral, Florida, on March 25, but added that “open work” remains. The military and the company are currently working through “risk reduction plans” to limit the chances of an issue with the first launch of a military payload on Vulcan.

“To address these challenges ULA has increased its engineering resources and management focus to resolve design issues,” Purdy wrote. “Government and Federally Funded Research and Development Center personnel have increased involvement in technical and program management challenges.

Vulcan’s first military mission, USSF-106, currently has a no earlier than launch date of July 2025, Purdy wrote. These outstanding risks will ultimately be assessed during a Flight Readiness Review a week or two prior to this launch.

At the end of his written testimony, Purdy emphasized that he expected ULA to do better. As part of his job as the Service Acquisition Executive for Space (SAE), Purdy noted that he has been tasked to transform space acquisition and to become more innovative.

“For these programs, the prime contractors must re-establish baselines, establish a culture of accountability, and repair trust deficit to prove to the SAE that they are adopting the acquisition principles necessary to deliver capabilities at speed, on cost and on schedule,” Purdy said.
