JAXA — the one that brought it back
Hayabusa returned the first pristine asteroid sample after every one of its critical systems failed. SLIM landed within ten metres of a spot on the Moon — the first pinpoint touchdown on another world. Kibo lets humans live in orbit. Epsilon cut launch prep from forty-two days to seven. Precision as identity.
The crucible, and Hayabusa
On 1 October 2003, three separate Japanese space bodies merged into one — the deep-space Institute of Space and Astronautical Science, the National Aerospace Laboratory, and the launch-vehicle-focused NASDA — to form JAXA. Within three months, the new agency was in crisis: H-IIA Launch Vehicle No. 6 had to be command-destroyed after a solid booster failed to separate, the ADEOS-II Midori II satellite went silent, and the NOZOMI Mars probe was declared lost.
The response was cultural, not just procedural. Every active project was reviewed to the bone. JAXA emerged committed to what its own history calls "absolute safety and meticulous engineering" — a discipline that would define everything it did afterward.
Which is why what came next is worth pausing on. In May 2003 — during those same first months of chaos — JAXA had launched Hayabusa (MUSES-C) to asteroid 25143 Itokawa. Over the next seven years it would suffer fuel leaks, reaction-wheel failures, lost communication with Earth, and an ion-engine breakdown in deep space. And on 13 June 2010 its return capsule streaked over the Australian outback and delivered the world's first pristine asteroid-surface samples — 1,500 microscopic grains of Itokawa's regolith — home.

"Everything failed in the first three months. Seven years later, they brought home the first asteroid sample ever collected."
Three programmes, running in parallel

Even while Hayabusa was fighting for its life in deep space, JAXA was executing two more first-tier programmes back home. In September 2007 the lunar orbiter KAGUYA (SELENE) launched with fifteen scientific instruments — and captured the public imagination by streaming the first-ever high-definition video of Earth-rise and Earth-set from lunar orbit.
In low-Earth orbit, Japan became a permanent physical presence on the International Space Station. Between 2008 and 2009, astronauts Takao Doi, Akihiko Hoshide, and Koichi Wakata installed and activated Kibo — "hope" — the largest single laboratory module on the ISS. Kibo was resupplied by JAXA's own heavy cargo craft, KOUNOTORI (HTV), which pioneered a precise autonomous rendezvous technique that other partners would later adopt as their model.

In March 2014, Koichi Wakata assumed command of Expedition 39, becoming the first Asian commander of the ISS. His mission patch carried the single character 和 — wa, meaning harmony — a deliberate choice about trust and teamwork under pressure. Wakata's command focused on the ISS's least-photogenic-but-most-important discipline: emergency drills. Ammonia leaks. Fires. Depressurization. The failure modes that decide whether a crew comes home.
On the ground, JAXA was rewriting rocket economics. On 14 September 2013, the Epsilon-1 launcher lifted off from Uchinoura Space Center. Epsilon was built as a "smart rocket" — its Responsive Operation Support Equipment (ROSE) ran AI-driven autonomous checks on the pad and slashed launch preparation time from the legacy M-V's forty-two days down to seven.
Ten metres, and a look at the violent universe
SLIM — the Smart Lander for Investigating Moon — launched on 7 September 2023 and touched down on 20 January 2024 with a position error of approximately ten metres from its target. The world's first "pinpoint" landing on another world. The moment humanity moved from landing where it can to landing where it wants.
SLIM came to rest on its side, its solar panels facing the wrong way. It was never designed to survive the two-week freeze of the lunar night. It survived three of them. Between wake-ups it ran its Multi-Band Camera on ten distinct rocks to reconstruct the local geology, until operations concluded in August 2024.
Overhead, launched the same year, the XRISM X-Ray Imaging and Spectroscopy Mission began delivering results. Its twin instruments — Xtend, a wide-field imager, and Resolve, an ultra-high-resolution microcalorimeter — resolve X-ray spectral lines with an energy precision below 5 eV. On 5 January 2024, first-light images landed: the colliding galaxy cluster Abell 2319, 770 million light-years distant; the detailed chemical spectrum of supernova remnant N132D in the Large Magellanic Cloud.

The next decade
JAXA's new mainstay launcher is the H3 — an LE-9-powered, expander-bleed-cycle rocket designed for cost, reliability, and payload flexibility. In August 2026, H3 Flight #9 delivered the Quasi-Zenith satellite MICHIBIKI No. 7 to orbit. Flight #10 will carry the Martian Moons eXploration (MMX) spacecraft to Phobos, where it will deploy a small rover, sample the surface, and — if all goes well — return that sample to Earth in 2031.
Further out sits LUPEX, a joint programme with ISRO targeting the lunar south pole no earlier than 2028. JAXA is providing the launcher — an H3 — and a heavy-duty 350 kg autonomous rover carrying the REIWA water-analyzer instrument suite. ISRO is providing the precision lander. The rover will drill up to 1.5 metres into the regolith of permanently shadowed craters, looking for extractable water ice.

And in lunar orbit, on the Artemis Gateway, Japan is delivering the I-Hab International Habitation module's environmental-control, life-support, batteries, and thermal-control systems. In exchange, JAXA astronauts will fly to the Gateway — and descend to the surface of the Moon.
"Brought back the first asteroid sample. Nailed the landing to within ten metres. Now going for a piece of Phobos."
