Airbus has been selected by the European Space Agency (ESA) as prime contractor for the Mars Sample Return’s Earth Return Orbiter (ERO) – the first-ever spacecraft to bring samples back to Earth from Mars. Mars Sample Return (MSR) is a joint ESA-NASA campaign and the next step in the exploration of Mars. ERO and the Sample Fetch Rover (SFR) are the two main European elements of MSR, both are set to be designed and built by Airbus. A manipulating arm referred to as the Sample Transfer Arm (STA), that will transfer the samples from the SFR to the Mars Ascent Vehicle (MAV), is the third European contribution to the MSR program. The value of the ERO contract is € 491 million.
The five-year mission will see the spacecraft head to Mars, act as a communication relay with the surface missions, perform a rendezvous with the orbiting samples, and bring them safely back to Earth. Prior to launch from the Mars surface onboard the MAV, the Martian samples will be stored in sample tubes and collected by the SFR, for which Airbus has already commenced the study phase.
For ERO, Airbus will use its autonomous rendezvous and docking expertise built up over decades of experience in optical navigation, using technologies from the successful ATV (Automated Transfer Vehicle) and recent developments from JUICE, Europe’s first mission to Jupiter.
“We’re bringing the full force of our experience gained on Rosetta, Mars Express, Venus Express, Gaia, ATV, BepiColombo, and JUICE to ensure this mission succeeds. Bringing samples back to Earth from Mars will be an extraordinary feat, taking interplanetary science to a new level and Airbus is excited to take on this challenge as part of this joint international mission,” said Jean-Marc Nasr, Head of Airbus Space Systems.
To be launched on an Ariane 6 in 2026, the 6 ton, 6 m high spacecraft, equipped with 144m² solar arrays with a span of over 40 m – some of the biggest ever built – will take about a year to reach Mars…more https://www.airbus.com/newsroom/press-releases/en/2020/10/airbus-to-bring-first-mars-samples-to-earth-esa-contract-award.html
