Moon

Flying to the moon just became a bit more realistic. Japanese billionaire Yusaku Maezawa is offering eight seats on a flight around the moon - for free. He wrote on Twitter that the seats had already been paid for. At first, the billionaire only wanted to take artists. But now, everyone who does something creative is eligible.

It is not known how expensive the moon orbit will be. The launch is planned for 2023. But he wants to check the applications for it this month. Those who get through will have to expect an interview and other tasks. The medical checks will then take place in May.

The billionaire and his crew will probably be the first to fly to the moon since the last US Apollo mission in 1972. The prerequisite for this is that SpaceX can get them into space.

Unlike previous detections of water in permanently shadowed parts of lunar craters, scientists have now detected the molecule in sunlit regions of the Moon's surface.

Speaking during a virtual teleconference, co-author Casey Honniball, a postdoctoral fellow at Nasa's Goddard Space Flight Center in Maryland, said: "The amount of water is roughly equivalent to a 12-ounce bottle of water in a cubic metre of lunar soil." Her Nasa colleague Jacob Bleacher, from the agency's human exploration directorate, said researchers still needed to understand the nature of the watery deposits.
