Richard Branson won the 'billionaire space race' over the weekend with his historic Virgin Galactic spaceflight - or did he?
World-famous astronomer Neil deGrasse Tyson says Branson's flight shouldn't count as 'space travel'.
In an interview with CNN, Tyson pointed out that Branson's flight was 'sub-orbital' and also didn't 'actually go somewhere' - compared to other space voyages that journey to the Moon or to Mars.
Tyson says Branson's flight was more like "getting a nice view of the Earth".
