Space tourists must be screened to ensure they are not terrorists, according to proposed regulations from the US Federal Aviation Administration.
The draft report’s suggestions aim to prevent a terrorist from destroying a spacecraft or using it as a weapon.
However, the report has no strict proposals on the health of any would-be space tourists.
The suggestions will affect Sir Richard Branson’s enterprise which aims to launch people into space this decade.
The Federal Aviation Administration (FAA) is attempting to regulate the commercial space industry in a bid to ensure minimum safety standards.
It has recommended security checks similar to those for airline passengers.
