FACTBOX: Space shuttle Endeavour's mission

(Reuters) - The U.S. space shuttle Endeavour lifted off on Tuesday with the first segment of Japan's contribution to the International Space Station. Here's a look at what's planned during the 122nd shuttle flight, the second of six missions scheduled for this year:

*Deliver and install a storage compartment stuffed with computers and gear for Japan's Kibo laboratory, the main part of which is due to arrive on NASA's next shuttle mission in May.

*Assemble a two-armed, Canadian-made robot named Dextre to be attached to the space station crane, effectively doubling its reach and giving it the ability to work with small items.

*Replace French astronaut Leopold Eyharts with NASA's Garrett Reisman, a first-time flier who is due to become the sole American on board the orbital outpost when two new Russian cosmonauts arrive in April.

*Test a technique to repair the space shuttle's heat shield should it be damaged by debris during launch or while in orbit.

*Use a power converter to tap electricity from the space station so that the shuttle can stay docked for 12 days.
