Aerospace engineer turned sex doll retailer Amit Stevenson has offered to provide SpaceXastronauts with sex dolls on their planned trip to Mars. The US and Europe-based company Sex Doll Genie says the journey to Mars will be lonely work and the company's robotic companions could keep Mars colonists company - rather than just sex. Mr Stevenson, who co-founded the firm with his wife Janet, has extended his offer to SpaceX CEO Elon Musk.
