Airbus To Build 'First Interplanetary Cargo Ship'

Airbus-France will build the huge satellite that brings the first Martian rock samples back to Earth. The BBC reports: This material will be drilled on the Red Planet by the US space agency's next rover, Perseverance, before being blasted into orbit by a rocket. It'll be the Airbus satellite's job to grab the packaged samples and then ship them home. The joint American-European project is expected to cost billions and take just over a decade to implement. But scientists say it's probably the best way to confirm whether life has ever existed on the Red Planet. Any evidence is likely to be controversial and will need the powerful analytical tools only found in Earth laboratories to convince the doubters, the researchers argue. The Airbus satellite will be a Goliath among spacecraft. The Earth Return Orbiter (ERO) will weigh 6.5 tonnes at launch in 2026 and use a mix of chemical and electric propulsion to get to Mars, orbit the planet and then return to Earth with its rock consignment. Thales Alenia Space of Italy will be a lead subcontractor working on this aspect of the design. The inclusion of a powerful ion engine will require a lot power, hence the use of immense solar arrays. These panels will give the satellite a "wingspan" of 39m, more than 120ft. But the really remarkable facet of the satellite's mission is the game of catch it will have to play high above Mars. Nasa will put a rocket on the planet later this decade to fire the rocks collected by Perseverance into orbit. The Airbus spacecraft will have to manoeuvre itself into a position to capture these samples that will be packaged inside a football-sized container. After ingesting this container, the satellite must then prepare it for return to Earth. "This is not just twice as difficult as any typical Mars mission; it's twice squared - when you think about the complexity involved," said Dr David Parker, the director of human and robotic exploration at the European Space Agency (Esa). "And this satellite that Airbus will build -- I like to call it 'the first interplanetary cargo ship,' because that's what it will be doing. It's designed to carry cargo between Mars and Earth," he told BBC News.
