“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.

Dr Parker announced the European aerospace company’s role in the Earth Return Orbiter (ERO) at a NASA-Esa briefing with reporters just ahead of Thursday’s launch of the Perseverance robot.
