A Joint Space Venture
In a significant stride for international space cooperation, the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) have formalized
their alliance to study the near-Earth asteroid Apophis. This partnership, solidified with a formal agreement signed in Berlin on May 7th, paves the way for the Rapid Apophis Mission for Space Safety, or Ramses. This ambitious mission is slated for a launch in April 2028, with the crucial objective of intercepting Apophis as it makes an exceptionally close, yet completely safe, pass by our planet in February 2029. The agreement details a collaborative effort where JAXA will contribute vital components, including advanced solar arrays and a thermal infrared imager, enhancing the mission's observational capabilities. The launch itself will be carried out by JAXA using their reliable H3 rocket, underscoring the depth of their commitment. This collaboration signifies a move from preliminary discussions to tangible mission execution, aiming to harness the rare opportunity presented by Apophis's proximity to gather unprecedented data about near-Earth asteroids.
Mission Objectives & Timeline
The Ramses mission is strategically designed to capitalize on a celestial event of immense scientific interest: the close approach of asteroid Apophis to Earth in February 2029. This flyby will bring the asteroid within approximately 32,000 kilometers of our planet's surface, a distance close enough for detailed observation but well within safe parameters. The primary goal of Ramses is to meticulously study Apophis during this encounter, with a particular focus on how the intense gravitational forces exerted by Earth will impact its surface and structure. Scientists are eager to understand the effects of such a close gravitational interaction, as it provides a unique window into the physical processes that shape asteroids. The mission is scheduled to arrive at Apophis roughly two months prior to its closest approach, allowing ample time for comprehensive data collection. The successful funding and formal adoption of the Ramses mission by ESA's ministerial council in November 2025, alongside JAXA's commitment, demonstrate a strong, unified international resolve to pursue this crucial scientific investigation.
Global Interest in Apophis
The impending close encounter with Apophis in 2029 has galvanized a global scientific community, spurring multiple proposed and developing missions aimed at studying this intriguing celestial visitor. Beyond the ESA-JAXA Ramses initiative, NASA is also involved through its OSIRIS-APEX mission, an extension of the OSIRIS-REx asteroid sample return mission. OSIRIS-APEX is expected to reach Apophis shortly after the asteroid's closest approach to Earth, providing further observational data. Despite potential funding uncertainties in NASA's budget proposals, historical congressional support suggests the mission may proceed. China, too, has put forth its own ambitious plans with the CROWN/Apophis mission, which envisions deploying two small spacecraft to study the asteroid post-flyby. Furthermore, private entities and other organizations are exploring innovative approaches, including ExLabs' mission concept funded through media and sponsorship, and HEO's proposal to utilize a geostationary orbit satellite at the end of its operational life for a flyby. This widespread interest highlights the scientific significance of Apophis and the collective human endeavor to understand our solar system.
