Japanese Startup's Kairos Rocket Aims for Third Launch

A small rocket company in Japan is proving that setbacks don't mean giving up on your dreams.

Space One, a Tokyo-based startup founded in 2018, is launching its Kairos rocket for the third time today from Spaceport Kii in Wakayama Prefecture. The 59-foot-tall rocket is scheduled to lift off during a 20-minute window starting at 9 p.m. EST.

The journey hasn't been easy. The first launch in March 2024 ended just five seconds after liftoff when safety systems detected performance issues. The second attempt in December lasted longer but had to be terminated three minutes into flight after the rocket reached 62 miles high.

Despite these challenges, Space One isn't backing down. The company carries five small satellites on today's mission, hoping to deploy them 50 minutes after launch at an altitude of 310 miles.

The Kairos rocket represents something bigger than just one company's ambition. It combines three solid-fuel stages with a liquid-propellant upper stage and can carry up to 330 pounds of payload to orbit.

The Ripple Effect

Space One's persistence matters for the growing small-satellite industry. The company aims to launch 20 missions per year by 2030 and 30 per year in the following decade, which could open new possibilities for smaller organizations and countries to access space.

Japan's private space sector is showing that innovation doesn't require perfection on the first try. Each launch teaches valuable lessons that bring the team closer to success.

The startup's willingness to try again quickly after failures demonstrates the kind of resilience that drives progress in tough industries.

If today's launch succeeds, it will mark a turning point for Space One and prove that determination combined with technical skill can overcome early setbacks.
