Japan plans to fly in space on the paper planes

The Cold War ended long ago, and mysteries in this world has become much less. I wonder what the researchers are now engaged in space? . Obviously, they are developing together paper airplanes capable of flying in space.

Currently being tested in a prototype vosmisantimetrovogo ... To make the test was considered a success, the plane has to withstand the conditions when the Mach number reaches seven, this would mean that the aircraft will be able to leave the Earth's atmosphere. It should be clear that the Mach number equal to seven ( there is a concept in aerodynamics ) corresponds to the relative wind speed of nearly 8500 km / h! . But for some reason would like to believe that this is true.
