Kairos, a small, solid-fuel rocket made by Japan's Space One, exploded just seconds into its inaugural launch on Wednesday as the firm tried to become the first Japanese company to put a satellite in orbit.

The setback for Space One and the rocket industry in Japan comes as the government and investors ramp up support for the sector amid a national security buildup and skyrocketing demand for commercial satellites.

The 18-meter (59 ft) rocket exploded five seconds after lifting off, leaving behind a large cloud of smoke, a fire, fragments of the rocket and sprays of firefighting water near the launch pad on the tip of mountainous Kii peninsula in western Japan, visible on local media livestreams.

"The rocket terminated the flight after judging that the achievement of its mission would be difficult," company president Masakazu Toyoda said.

Space One did not specify what triggered self-destruction after the first-stage engine ignited - or when the company would launch the next Kairos - only pledging an investigation into the explosion.

The company said that the launch is highly automated, requiring only about a dozen ground staff, and that the rocket self-destructs when it detects errors in its flight path, speed or control system that could cause a crash that endangers people on the ground.

"We don't use the word 'failure', because each trial brings us ... new data and experience for another challenge," Toyoda told a news conference.

There were no injuries near the launch pad, and the fire has been extinguished, Shuhei Kishimoto, governor of Wakayama prefecture, told reporters.

Kairos carried an experimental government satellite that can temporarily replace intelligence satellites in orbit if they fall offline.

Space One had planned the launch for Saturday but postponed it after a ship entered the nearby restricted sea area.

‘Space courier services’

Although Japan is a relatively small player in the space race, the nation's rocket developers are scrambling to build cheaper vehicles to capture booming demand for satellite launches from its government and from global clients.

Tokyo-based Space One was established in 2018 by a consortium of Japanese companies: Canon Electronics, the aerospace engineering unit of IHI, construction firm Shimizu and the state-backed Development Bank of Japan. Two of Japan's biggest banks, Mitsubishi UFJ and Mizuho, also own minority stakes.

Shares in Canon Electronics fell as much as 13%, while IHI shares were down as much as 2% after Wednesday's failed launch.

Space One wants to offer "space courier services" to domestic and international clients, aiming to launch 20 rockets a year by the late 2020s, Toyoda has said. Although the company delayed Kairos' inaugural launch window four times, it said orders for its second and third planned trips have been filled, including by an overseas customer.

Kairos is composed of three stages of solid-fuel engines and a liquid-fuel post-boost stage engine, attempting to carry payloads of up to 250 kg to low-Earth orbit.

Space One does not disclose Kairos' launch costs, but company executive Kozo Abe said it is "competitive enough" against American rival Rocket Lab.

Rocket Lab has launched more than 40 Electron small rockets from New Zealand since 2017 at roughly $7 million per flight. Several Japanese companies have used Electron for their missions, including radar satellite makers iQPS and Synspective, and orbital debris-removal startup Astroscale.

Revitalizing an industry

Partnering with the United States, Japan is seeking to revitalize its domestic aerospace industry to counter technological and military rivals China and Russia.

Last month, state-funded Japan Aerospace Exploration Agency (JAXA) successfully launched its new cost-efficient flagship rocket, the H3. JAXA completed a historic "pinpoint" moon landing this year, and the H3 is scheduled to carry about 20 satellites and probes to the space by 2030.

Before that, however, JAXA had faced a series of setbacks. H3's inaugural flight failed last year, as did another flight of a smaller rocket, Epsilon, in 2022. In July 2023, an upgraded engine for Epsilon exploded at JAXA's testing site.

In 2019, Interstellar Technologies conducted Japan's first privately developed rocket launch with its MOMO series, although without a full-scale satellite payload.

The government last year promised "comprehensive" support for space startups with technology critical for national security, as it seeks to build satellite constellations to ramp up intelligence capabilities.

Japan's defense ministry on Friday said it had struck a deal with Space One to boost its rockets' payload by experimenting with fuel-efficient methane engines.

"Rocket Lab, too, did not achieve its mission at the inaugural (Electron) flight, but it went on to launch three rockets in its second year," Toyoda said. "We can't stop here – we need to compete with this company."

Ten black rhinos have been moved from South Africa to Mozambique to secure breeding of the critically endangered animals that became locally extinct 50 years ago, conservationists said Thursday.

The five male and five female rhinos were transferred to Mozambique's Zinave National Park in a 48-hour road trip last week, said the Peace Parks Foundation, which took part in the translocation.

"It was necessary to introduce these 10 to make the population viable," communication coordinator Lesa van Rooyen told AFP.

The new arrivals will "secure the first founder population of black rhinos since becoming locally extinct five decades ago,” South Africa's environment ministry, which was also involved, said in a statement.

Twelve black rhinos had previously been sent from South Africa to Zinave in central Mozambique but the population was still not viable for breeding, Van Rooyen said.

Twenty-five white rhinos, which are classified as less threatened, were also translocated in various operations.

The global black rhino population dropped by 96 percent between 1970 and 1993, reaching a low of only 2,300 surviving in the wild, according to the International Rhino Foundation.

Decades of conservation efforts allowed the species to slowly recover and the population is estimated at 6,421 today.

Once abundant across sub-Saharan Africa, rhino numbers fell dramatically due to hunting by European colonizers and large-scale poaching, with their horns highly sought after on black markets particularly in Asia.

Mozambique's population of the large animals was depleted during the 15-year civil war, which ended in 1992 and pushed many people to desperate measures to "survive in very difficult circumstances", van Rooyen said.

Years of rewilding efforts have established Zinave as Mozambique’s only national park home to the "Big Five" game animals -- elephant, rhino, lion, leopard and buffalo.
