ESA awards contracts for Ramses mission to Apophis

The contract, price €81.2 million, was signed at present by ESA and OHB Italia at ESA’s ESTEC know-how centre within the Netherlands and begins the spacecraft building, meeting and testing section of the Ramses mission.

This builds upon the contract signed in October 2024 to start preparatory work on the mission and brings the whole worth to roughly €150 million.

“With Ramses, ESA is seizing a once-in-a-lifetime alternative to review asteroid Apophis because it swings previous Earth, deepening our understanding of near-Earth objects and advancing our capabilities to guard our planet,” stated Orson Sutherland, Mars & Past Tasks Group Chief at ESA.

“The mission demonstrates European trade’s excellence and our dedication to worldwide cooperation, whereas pushing the boundaries of robotic house exploration and provoking individuals around the globe.”

“We’re proud to be entrusted by ESA with the Ramses mission,” stated Roberto Aceti, CEO of OHB Italia.

“This contract displays the boldness positioned in our group’s experience and decades-long heritage in delivering advanced house methods. We look ahead to working with ESA and our companions to ship this actually bold mission for planetary defence.”

The Ramses group assembles

By bringing onboard OHB, the Ramses mission capitalises on the wealth of expertise developed throughout Europe in the course of the building of ESA’s first planetary defence mission, Hera, which can arrive on the Didymos binary asteroid system later this yr.

Like Hera, Ramses will carry two deployable CubeSats developed by European trade and designed to increase the mission’s scientific attain as soon as it arrives at Apophis.

A second contract price €8.2 million was signed at present with Italy’s Tyvak International for the development of one among Ramses’ CubeSats, named Farinella after the Italian planetary scientist Paolo Farinella. As with the primary Ramses spacecraft, this builds on an earlier contract price €4.7 million awarded for preparatory work final yr.

“We’re excited to tackle the problem of delivering a small spacecraft that may make a giant contribution to the examine of the asteroid Apophis throughout its historic shut Earth flyby,” stated Fabio Nichele, CEO of Tyvak Worldwide.

“This mission highlights the power of European industrial collaboration and underscores how revolutionary small satellites can play a key position in advancing planetary science and safeguarding our planet.”

The Ramses mission additionally brings in experience from past Europe. Ramses is a joint mission by ESA and the Japan Aerospace Exploration Agency (JAXA).

JAXA’s contributions embrace spacecraft elements such because the photo voltaic arrays and thermal infrared imager, and a possible rideshare launch with JAXA’s Future+ mission. Japanese researchers additionally take part in Ramses’ scientific actions.

A singular alternative

Ramses will rendezvous with the near-Earth asteroid (99942) Apophis forward of its extremely uncommon and scientifically beneficial flyby of Earth on 13 April 2029. The occasion will deliver the roughly 375-metre object inside about 32 000 km of our planet – lower than one tenth the gap from Earth to the Moon.

Scientists around the globe are keen to watch how the asteroid’s form, spin and construction reply to Earth’s gravitational forces throughout this uncommon, however completely protected, encounter. The insights gained from this pure experiment will improve our understanding of how near-Earth objects behave below exterior forces.

That is crucial information for future planetary defence methods towards probably hazardous asteroids. Ramses will thus contribute considerably to the core purpose of ESA’s Area Security Programme to guard Earth from pure and humanmade hazards originating in house.

Time to construct

The Ramses Vital Design Assessment, performed by ESA’s skilled overview board over the previous couple of months, concluded on 6 February. It confirmed that the detailed design of the Ramses spacecraft meets all technical, scientific and programmatic necessities.

“Passing the Vital Design Assessment in report time provides us full confidence that Ramses’ design is mature, strong and able to be constructed,” stated Paolo Martino, Ramses mission supervisor.

“Efficiently sustaining the mission’s accelerated tempo is an endorsement of the group’s dedication and engineering imaginative and prescient below a really demanding schedule.”

With this crucial milestone behind it, and the contract signed, the Ramses group will now deal with constructing, assembling and testing the flight spacecraft and its methods. Over the following yr, {hardware} elements similar to the primary spacecraft bus and payload devices shall be assembled and built-in.

This shall be adopted by rigorous environmental and purposeful exams to organize the mission for its deliberate launch window in Spring 2028.
