Californi­a-based Galactic Resource Utilization Space, also known as Gru or Gru Space, says it is now accepting deposits from wealthy adventure-seekers who want to be among the first guests at a lunar hotel planned for as early as 2032.

Applicants must first pay a non-refundable US$1,000 application fee. If selected, they can then choose to make a US$250,000 to US$1 million refundable deposit to reserve a spot at the future lunar hotel.

Ultimately, a stay at the lunar hotel could cost about US$10 million per guest, once launch, transport, accommodation, training and operational costs are included. The average stay would be five nights.
