Elon Musk's ambitious space plans are no secret, even as his company SpaceX aims to send humans into space. In a usual Twitter chatter, however, Mr Musk revealed how much a ticket to Mars could cost when SpaceX's mission goes live.
In a response to a tweet asking the estimated costs for tickets to Moon or Mars accounting for reusability, Mr Musk replied that the costs are dependent on volume.
However, he said he was confident that moving to Mars will one day would cost less than $500,000 or even lesser than $100,000, inclusive of a return ticket.
Mr Musk considers this cost low enough for people in advanced economies to sell their home on Earth and move to the Red Planet, if they so wish.
Although moving to Mars is the ambitious mission, Mr Musk's teams are prioritising Moon as a habitable alternative to Earth.
