Resolution Criteria:
Fully Operational: The space hotel must be functioning and able to accommodate guests for overnight stays. This includes having life support systems, sleeping quarters, and other necessary amenities for a hotel functioning properly.
Commercially Available: The space hotel must be open to the public and not just astronauts or employees of space agencies. Stays must be available for purchase by the general public. It doesn't necessarily need to be affordable to the average person, but it should not be restricted to particular institutions or professions.
Hotel in Space: The hotel must be located in space, defined as being beyond the Kármán line (an altitude of 100 kilometers or about 62 miles above Earth's sea level), which is widely accepted as the boundary of outer space.
Deadline: The space hotel must be fully operational and accepting guests on or before December 31, 2028.
Judgement: Compliance with these criteria can be validated through reputable media reports, company press releases, or regulatory filings.
