But, where, oh where is the celebration Google doodle for that other epic life voyage of space shuttle Endeavour?

The fifth and final NASA space shuttle to be built, was constructed as a replacement for Challenger and first flew in 1992.

Commanded by Mark Kelly (left) and carrying European-built Alpha-Magnetic Spectrometer ( Courtesy: NASA) and ESA (right) mission specialist Roberto Vittori, Endeavour  is due to blast off from Kennedy Space Centre 19:47:52 GMT 29 April.

The AMS is a particle physics experiment module to be mounted on the International Space Station.

Designed to search for various types of unusual matter by measuring cosmic rays, its experiments will help researchers study the formation of the Universe and search evidence of dark matter and antimatter.

Also on board, from North Western University's McCormick School of Engineering and Applied Science, is Professor Mark Hersam's carbon nanotube and graphene thin films that must prove themselves in space.

The materials will spend at least six months on the exterior of the International Space Station. Hersam has a duplicate set of the materials in his lab that will be tested those alongside the space-traveling set when it returns to Earth.

All that may not touch hearts and minds like youth, royalty, love and marriage, but it could have a major impact in lighting up the unknown.
