Private rocket explodes seconds after launch

Japanese firm maintains flight deliberately aborted

A rocket made by a Japanese company exploded seconds after launch yesterday, in a spectacular failure for the startup’s bid to put a satellite into orbit.

Tokyo-based Space One’s 18m Kairos rocket blasted off from the company’s launch pad in the Wakayama region of western Japan, carrying a small government test satellite.

But seconds later, the solid-fuel rocket erupted into balls of flame, sending smoke billowing into the remote mountainous area, live footage showed.

“The launch of the first Kairos rocket was executed, but we took a measure to abort the flight,” Space One said in a statement, adding that “details are being investigated”.

Burning debris fell onto the surrounding slopes as sprinklers began spraying water in dramatic scenes watched by hundreds of spectators young and old gathered at public viewing areas including a nearby waterfront.

“I had high hopes for this, so I’m disappointed. I want to know what happened,” one elderly man told public broadcaster NHK.

The fiery failure marks a blow to Japan’s efforts to enter the potentially lucrative satellite-launch market.

The government wants to assess if it can quickly launch using small satellites from private firms to complement its existing satellites gathering intelligence, including on North Korea’s missile activities.

Success yesterday would have given it an insight into the feasibility of such programmes.

The plan had been for Kairos – an ancient Greek word meaning “the right moment” – to put the satellite into orbit around 51 minutes after take-off.

Parts shortages and other problems had reportedly led Space One to postpone the launch of Kairos five times before this attempt, most recently on Saturday.

The mayor of Kushimoto, the town of 15,000 residents in Wakayama where the failed launch took place, voiced his surprise and disappointment.

“I didn’t even imagine an outcome like this,” said Katsumasa Tashima.

But the town “will continue to support Space One, and we want to continue to offer our help so that the first rocket will have a successful launch”, he said.

Space One was established in 2018 by a team of major Japanese tech businesses, including Canon Electronics, IHI Aerospace, construction firm Shimizu and the government-owned Development Bank of Japan.

Last month, Japan’s space agency toasted a successful blast-off for its new flagship rocket, the H3, after years of delays and two previous failed attempts.

The H3 has been mooted as a rival to SpaceX’s Falcon 9, and could one day deliver cargo to bases on the Moon.

That followed Japan’s successful landing in January of an unmanned probe on the Moon – albeit at a wonky angle – making it just the fifth country to achieve a “soft landing” on the lunar surface.

In April last year, another Japanese start-up, ispace, tried in vain to become the first private company to land on the Moon – losing communication with its craft after what it described as a “hard landing”.
