The "G-SATELLITE Go to Space" project will see Mobile Suit Gundam TV series figures Gundam and Zaku sent into space on an 11-inch microsatellite next spring.

It will represent a first time in Olympic and Paralympic history that a satellite will be launched specifically for the Games and orbit the earth independently.

Gundam and Zaku are two of Japan's most popular animated robots and the project will see a recreation of the characters using special materials and paints that can withstand the harsh environment of space.

The Olympic Games are scheduled to take place from July 24 to August 9, with the Paralympics following from August 25 to September 6.
