ESA and JAXA finalize settlement on Apophis asteroid mission

WASHINGTON — The European Space Agency and Japan Aerospace Exploration Agency have finalized an settlement to collaborate on a mission to check the asteroid Apophis throughout its shut flyby of Earth in 2029.

In a May 7 ceremony in Berlin, the heads of ESA and JAXA signed a cooperation settlement for the Rapid Apophis Mission for Space Safety, or Ramses, scheduled to launch in 2028.

Under the settlement, JAXA will present photo voltaic arrays and a thermal infrared imager instrument for Ramses. It may even launch the mission on an H3 rocket in April 2028.

ESA and JAXA introduced in November 2024 their intent to collaborate on Ramses, working first to establish potential Japanese contributions to the mission. The settlement got here after each businesses secured funding for the mission, together with formal adoption of Ramses at ESA’s November 2025 ministerial council assembly.

“With today’s signatures, ESA and JAXA are moving decisively from shared intention to concrete implementation, translating commitment into mission-level cooperation,” ESA Director General Josef Aschbacher mentioned in a press release.

“We sincerely appreciate ESA and its member states, including Italy, and expect this cooperation to further advance international efforts in this field,” mentioned JAXA President Hiroshi Yamakawa. Italian firm OHB Italia is the prime contractor for Ramses.

Ramses will arrive at Apophis in February 2029, about two months earlier than the asteroid makes a really shut, however secure, method to Earth, passing as shut as 32,000 kilometers from the floor. The shut flyby gives a uncommon alternative for detailed research of close to Earth asteroids, together with how the gravitational results of the flyby alter the asteroid’s floor.

It is one in every of a number of missions proposed or in growth to go to Apophis earlier than or after the flyby. NASA’s OSIRIS-APEX, an extension of the OSIRIS-REx asteroid pattern return mission, will arrive at Apophis simply after the flyby. NASA’s fiscal yr 2027 funds proposal gives no funding for the mission, however Congress overrode an identical proposed cancellation in 2026.

Chinese scientists have proposed their very own Apophis mission, referred to as CROWN/Apophis, that will ship two small spacecraft to the asteroid simply after the flyby.

Several different corporations and organizations have additionally supplied plans for Apophis missions in the course of the 2029 encounter. That contains ExLabs, which has developed a mission idea that will be supported by income from media and sponsorship offers, and Australian area imaging firm HEO, which has proposed utilizing a geostationary orbit satellite tv for pc on the finish of its life to fly by the asteroid.
