The European Space Agency (ESA) yesterday announced that it has awarded the aerospace company OHB Italia a $96 million contract to build Ramses probe to rendezvous with the potentially dangerous asteroid Apophis when it makes its next close fly-by of Earth in 2029.
This contract is in addition to the $75 million development contract awarded OHB Italia in 2024. According to the company’s press release here:
The launch is scheduled for April 2028, with a rendezvous with Apophis planned for February 2029, approximately two months before its close approach to Earth. The spacecraft will accompany the asteroid until August 2029, in order to observe in detail how Earth’s tidal forces modify its shape, rotation, orbit and surface characteristics.
The initiative also benefits from strong international cooperation. The Japan Aerospace Exploration Agency (JAXA), drawing on its well-established expertise in asteroid science, will contribute by providing launch service onboard an H3 rocket, the spacecraft’s solar arrays and a Thermal Infrared Imager, further reinforcing the project’s global dimension.
In addition, two cubesats will be launched with Ramses and deployed once the spacecraft reaches Apophis.
This schedule is very tight, which places great pressure on OHB, especially because European space projects are traditionally built slowly after years of planning. ESA almost never does things fast like this.
At the moment, Osiris-Apex (formerly Osiris-Rex) is the only spacecraft that is on its way to Apophis.
