ESA awards contracts for Ramses mission to Apophis
ESA Awards Contracts for Ramses Mission to Apophis: A Landmark in Planetary Defence
On 10 February 2026, the European Space Agency (ESA) took a significant step forward in its mission to protect Earth from near-Earth objects (NEOs) by awarding contracts for the development of the Rapid Apophis Mission for Space Safety (Ramses). Worth €81.2 million, the contract was signed with OHB Italia, a leading European space industry player, and marks the beginning of the spacecraft construction, assembly, and testing phase of the Ramses mission.
A Rare Opportunity to Study Apophis
The Ramses mission is designed to rendezvous with the asteroid Apophis, a 375-meter object that will make a rare and scientifically valuable flyby of Earth on 13 April 2029. The event will bring the asteroid within about 32,000 km of our planet, less than one-tenth the distance from Earth to the Moon. Scientists around the world are eager to observe how the asteroid's shape, spin, and structure respond to Earth's gravitational forces during this rare, but entirely safe, encounter.
A Key Component of ESA's Space Safety Programme
The Ramses mission is a key component of ESA's Space Safety Programme, which aims to protect Earth from natural and human-made hazards originating in space. The programme has already made significant progress in advancing our understanding of NEOs and developing strategies for planetary defence. The Ramses mission will contribute significantly to this goal by providing unique insights into the physical properties and behavior of asteroids.
OHB Italia's Expertise in Spacecraft Development
OHB Italia has a long history of developing complex space systems, including the Hera mission, which will arrive at the Didymos binary asteroid system later this year. The company's expertise in spacecraft development, combined with its experience in working with European industry partners, makes it an ideal partner for the Ramses mission.
A Joint Mission with JAXA
The Ramses mission is a joint mission between ESA and the Japan Aerospace Exploration Agency (JAXA). JAXA's contributions include spacecraft components such as the solar arrays and thermal infrared imager, as well as a potential rideshare launch with JAXA's Destiny+ mission. Japanese researchers also participate in Ramses' scientific activities, highlighting the strength of international collaboration in space exploration.
The Ramses Team Assembles
The Ramses team is comprised of experts from across Europe, including OHB Italia, Tyvak International, and other industry partners. The team has already made significant progress in developing the mission's design and is now focused on building, assembling, and testing the flight spacecraft and its systems.
A Critical Design Review
The Ramses Critical Design Review, conducted by ESA's expert review board over the last few months, concluded on 6 February. The review confirmed that the detailed design of the Ramses spacecraft meets all technical, scientific, and programmatic requirements. Passing the Critical Design Review in record time gives the team full confidence that Ramses' design is mature, robust, and ready to be built.
A Forward-Looking Mission
The Ramses mission is a forward-looking mission that will provide unique insights into the physical properties and behavior of asteroids. The mission will also contribute significantly to the core goal of ESA's Space Safety Programme to protect Earth from natural and human-made hazards originating in space. As the mission progresses, it will provide valuable lessons for future planetary defence strategies and inspire new generations of space explorers.
Implications for Planetary Defence
The Ramses mission has significant implications for planetary defence. By studying the physical properties and behavior of asteroids, scientists can better understand how to deflect or disrupt potentially hazardous asteroids. The mission will also provide valuable insights into the dynamics of asteroid orbits and the effects of gravitational forces on asteroid shapes and structures.
Conclusion
The ESA's award of contracts for the Ramses mission to Apophis marks a significant step forward in the agency's mission to protect Earth from near-Earth objects. The mission will provide unique insights into the physical properties and behavior of asteroids and contribute significantly to the core goal of ESA's Space Safety Programme to protect Earth from natural and human-made hazards originating in space. As the mission progresses, it will provide valuable lessons for future planetary defence strategies and inspire new generations of space explorers.
