It's usually "Earth to Mars" calls that get placed, but recently it was the other way around.

British astronaut Tim Peake, the first British European Space Agency astronaut, phoned home on Thursday to wish someone a Merry Christmas but dialed a wrong number.

He sent out an apology on Twitter, saying, "I'd like to apologise to the lady I just called by mistake saying 'Hello, is this planet Earth?' - not a prank call...just a wrong number!"
