The space shuttle Discovery is all set for its final take-off. Strapped to a jumbo jet, NASA's oldest and most-traveled space shuttle will take off from Florida's Kennedy Space Center and land at the Smithsonian National Air and Space Museum's in Virginia.

Depending on the weather conditions, the shuttle will fly south down the Cape Canaveral beach to facilitate public view before turning north, Associated Press reported.

After a three-decade long service, Discovery now will spend its future as a museum piece and it is the first space shuttle placed in a museum. Of the other two retired space shuttles, the Endeavour will head to Los Angeles, while the Atlantis will remain at the Kennedy space center, AP reported.

After its 39th and last mission in March 2011, the spaceship was prepared for public display at NASA's Orbiter Processing Facility-1 (OPF-1) at the Kennedy Space Center in Florida. The key components were removed from the space shuttle for future reuse. Many other changes and alterations were also carried out to make it safe for public display.

Here is a glimpse in pictures of Discovery's life and final journey preparations.
