Japan to launch origami planes into outer space

In a bold bid to take the traditional art of origami beyond the Final Frontier, Japan is planning to release a huge squadron of paper aeroplanes in outer space.
The trailblazing experiment, slated for launch later this year, could see around 100 paper planes raining down on the planet as they are captured by the Earth’s gravitational pull and sucked down towards the surface.
Astronomers and star-gazers should have plenty of warning of the planes’ arrival, though: Shinichi Suzuki, the University of Tokyo professor behind the scheme, believes the paper flotilla will take several months to complete its gentle, gliding descent from upper atmosphere to the planet’s surface.
The origami planes, which will measure around 20cm each and weigh just 30 grams, are to be hurled into the void by a Japanese astronaut scheduled to visit the International Space Station this summer.
The experiment would, if successful, qualify for the longest ever flight by a paper plane: if one of the fleet should miraculously make it to earth, its journey will have been around 400km.
If any do make it back, the planes are statistically most likely to land in the sea - performing the same “splashdown” as the Apollo space missions. In the unlikely event that one floats down to solid ground, the lucky finder will be able to unfold the plane and discover the return address at the Japan Space Agency.
“It’s going to be the space version of a message in a bottle. It will be great if someone picks one up,” said Prof. Suzuki, “We are thinking of writing messages on the planes saying ’if found, please contact us’ in a couple of languages.” The idea comes as Japan is desperately trying to generate interest in its conventional space programme. Many Japanese have lost interest in the exploits of the nation’s Space Agency (JAXA) because of a string of embarrassing rocket launch failures.
Recent media reports have also cast doubt on the prospects of the GX rocket - a project that has encountered acrimonious wrangling over which government ministry should be in charge of which section of the fuselage.
The paper aircraft, meanwhile, are to be constructed from a specially heat-proofed paper able to withstand the astonishing temperatures liable to be experienced upon re-entry. The paper will also be chemically fortified to survive the enormous speeds that the planes will be travelling at as they are pulled into the earth’s orbit and breach the outer atmosphere.
In recent experiments by the Japan Origami Airplane Association, the prototypes have withstood speeds of Mach 7 and temperatures of 300C before disintegrating. The design of the planes - not unlike the United States Space Shuttle - is also calculated to minimise the destructive effects of re-entry.
There is serious scientific intent behind the plan. Japan believes that if the paper planes are successful, they may open possibilities of using softer, lighter materials for constructing space craft.
Japan’s recent relationship with outer space has been controversial. In December, the Japanese Government was asked in parliament to produce a position paper on the existence of UFOs, prompting the chief cabinet secretary, Nobutaka Machimura, to declare his belief that aliens are “definitely” out there.
Later the same day, Yasuo Fukuda, the Prime Minister, separately told reporters, ”I have not yet confirmed” the existence of UFOs.

space paperplane, ping!
Litterbugs!
“Why not just build a wicker tank?” /VeryObscure
Ping!
thanks, bfl
I expect the plane will get hotter than 300 C.
Guess there are no more important problems left to throw money at.
A few minutes later he would open the window and the airplane would fly back in.
As if there is not enough junk up there already
Taking a short break from pondering about a new round of their recession.:-)
The plan looks good on paper, but ...
My thoughts exactly.
Whimsical and cool. Good old Japan.
Are they aimed at Pearl Harbor?
Maybe they should make their little airplanes out of paper money so they dabble it away faster.
