Still early days — Japan is studying a reusable rocket, but it wont fly before 2030 This launcher would replace the H3 rocket, which hasn’t yet become operational.

Japan debuted the new flagship H3 rocket in March, capping a decade-long, nearly $1.5 billion development effort to replace a launch vehicle that has been in service for more than 20 years. The H3’s upper stage failed to ignite a few minutes after liftoff, causing the rocket and its Earth observation payload to crash into the Pacific Ocean.
Officials in the Japanese government are already plotting the replacement for the H3 rocket, which had a goal of cutting in half the cost per launch of the H-2A launcher, a workhorse for Japan’s space program. But the H3 is based on a single-use, expendable design, like nearly all legacy rockets. The H3 design aims to achieve these cost savings through modernized manufacturing techniques and commonality in hardware with Japan’s smaller Epsilon rocket family.
The Japanese government updated its basic plan on space policy in June with language endorsing the development of a reusable rocket to follow the H3. Now, the Japan Aerospace Exploration Agency (JAXA) has tapped Mitsubishi Heavy Industries for joint studies on the next-generation launcher, which would have a recoverable and reusable first-stage booster, Space News reported this week.
There’s no design yet for this still-unnamed rocket. A JAXA spokesperson told Space News that engineers haven’t settled on a fuel. It could be cryogenic methane, the fuel favored by most companies developing new reusable launch rockets, or Japan could stick with liquid hydrogen, the super-cold fuel used on the H-2A and H3 rockets.

The space policy document released by Japan’s Cabinet Office in June outlined several key technologies necessary for the country’s next-generation rocket. Those included rocket reuse tech, innovative materials, methane-fueled propulsion, and modernized production capabilities. Japanese policymakers wrote the new rocket, replacing the H3, would start flying in the 2030s.
“By reusing parts … we will improve launch frequency and transportation capacity, and reduce launch costs,” Japanese government officials wrote in the policy plan.
SpaceX’s demonstration of the benefits of reusable rockets has inspired others to pursue similar capabilities. Rocket Lab, the US-New Zealand company that operates the light-class Electron launcher for small satellites, has successfully recovered boosters and recently reused an engine from a previous flight. In the coming months, Rocket Lab plans to reuse an entire set of nine booster engines on a launch. The company is developing a new rocket named Neutron with a booster stage designed from the start to be entirely reusable.
Blue Origin and several other companies also may be a few years away from reusing boosters on their orbital-class rockets. United Launch Alliance’s new Vulcan rocket is powered by Blue Origin-built BE-4 engines. ULA plans to eventually recover the engines and reuse them but doesn’t plan to retrieve the entire first stage of the Vulcan rocket.
Other rocket builders, like Europe’s ArianeGroup, went all-in with a new expendable rocket, similar to Japan’s approach with the H3. Europe’s expendable Ariane 6 rocket won’t fly until next year, at the earliest. The European Space Agency and European industrial partners are in the early stages of designing a reusable methane-fueled engine that could lead, in the longer term, to a reusable replacement for the Ariane 6. But like Japan’s new reusable rocket study, a follow-on to the Ariane 6 would likely not fly until 2030 or later.

The US joined Russia to vote against a UN resolution on the Ukraine war – and abstained from voting on one it drafted after amendments proposed by European countries were added.
The 193-member assembly approved a US-drafted resolution, marking the third anniversary of Russia’s invasion of Ukraine, which had originally called for an end to the conflict but did not mention Moscow’s aggression.
It also made no mention of Ukraine’s territorial integrity.
However, it was amended after European nations said that it should include references to Russia’s full-scale invasion of Ukraine and the need for a lasting peace in line with the UN Charter.
It was also amended to include references to Ukraine’s sovereignty.
The amended US-drafted resolutionwon 93 votes in favour, while 73 states abstained – including the US – and eight – including Russia – voted no.

On the same day, the UN General Assembly approved a European-backed resolution from Ukraine which demanded Russia immediately withdraw from the country.
There were also 93 votes in favour of this resolution,while 65 abstained and 18 voted against it.
The UK, France and Germany were among the countries that voted in favour of the Ukraine-backed resolution, which called for a “comprehensive, just and lasting peace in Ukraine”.
The US, Russia, Belarus and North Korea were among those that opposed it.

The duelling proposals reflect the tensions that have emerged between the US and Ukraine after Donald Trump suddenly opened negotiations with Russia in a bid to quickly resolve the conflict.
It also underscores the strain in the US’ relationship with Europe over the Trump administration’s decision to engage with Moscow.
The outcome marks a setback for the Trump administration in the UN General Assembly, whose resolutions are not legally binding but are seen as a barometer of world opinion.
However, later in the day, the UN Security Council approved the US resolution calling for an end to war in Ukraine – but without mentioning Russia’s aggression. The resolution received 10 votes in favour, while the remaining five members – including France and the UK – abstained.
Dame Barbara Woodward, the UK’s ambassador to the United Nations, said after the UN Security Council approved the motion: “What, how and on what terms this war ends can only be decided by negotiations with Ukraine.
“No peace will be sustainable without Ukraine’s consent.
“We regret that our proposals making these points clear were not taken on board, and as such we could not support this resolution.
“But we share the ambition to find a lasting end to this war, supported by robust security arrangements that ensure Ukraine never again has to face Russia’s attack.”
It came after the results in the General Assembly had showed some diminished support for Ukraine – as more than 140 nations had voted to condemn Russia’s aggression in previous votes.
The United States had tried to pressure the Ukrainians to withdraw their resolution in favour of its proposal, according to a US official and a European diplomat.
US deputy ambassador Dorothy Shea, meanwhile, said multiple previous UN resolutions condemning Russia and demanding the withdrawal of Russian troops “have failed to stop the war,” which “has now dragged on for far too long and at far too terrible a cost to the people in Ukraine and Russia and beyond”.
“What we need is a resolution marking the commitment from all UN member states to bring a durable end to the war,” Ms Shea said.
Mr Zelenskyy responded by saying the US president was living in a Russian-made “disinformation space”.
Meanwhile, French President Emmanuel Macron is at the White House holding talks with Mr Trump to discuss a peace plan for Ukraine.
At the start of the meeting, Mr Trump told reporters Russian President Vladimir Putin will accept European peacekeepers in Ukraine as part of a potential deal to end the war in the country.
Mr Trump and Mr Macron have been meeting after the pair had earlier joined a call between G7 leaders.

Zevtron, ParkMobile, and Athena Partners Strategy Group are together supporting charging site owners and EV drivers affected by Shell Recharge’s shutdown of its EV charger software.
Shell Recharge is discontinuing its Shell Sky software in third-party commercial EV chargers in the US and Canada. It will service third-party commercial fleet EV chargers until April 30; after that, it’s lights out, leaving hundreds of EV charging stations across the US inoperable.
Zevtron, ParkMobile, and Athena Partners Strategy Group is deploying Zevtron’s white-label EV charging software across the former Shell Recharge network to restore full operational capacity to these chargers.
“Shell’s exit has left hundreds of chargers effectively stranded,” said Chris Mckenty, SVP of sales & marketing at Zevtron. “Our goal is to rapidly restore these stations to full functionality while enhancing their capabilities with flexible branding, seamless payment options, and improved management tools.”
