Discovery is ready for a 5 April launch on its STS-131 mission to the International Space Station.

The shuttle will blast off from Kennedy Space Center's Launch Pad 39A at 10:21 GMT, carrying the Leonardo multi-purpose logistics module filled with "supplies, a new crew sleeping quarters and science racks that will be transferred to the station's laboratories".

The 13-day mission will feature "three spacewalks to switch out a gyroscope on the station's truss, or backbone, install a spare ammonia storage tank and return a used one, and retrieve a Japanese experiment from the station's exterior".

On board will be commander Alan Poindexter and pilot Jim Dutton (seated right and left), and (l-r) mission specialists Rick Mastracchio, Stephanie Wilson, Dorothy Metcalf-Lindenburger, Japan Aerospace Exploration Agency (JAXA) astronaut Naoko Yamazaki and NASA astronaut Clayton Anderson:

Anderson and Yamazaki are both twittering away like good 'uns during their pre-launch training, and plan to tweet from orbit, NASA says. The agency has the usual mission page here, mission summary here (pdf) and press kit here (pdf).

Up on the ISS, meanwhile, crew members TJ Creamer, Oleg Kotov and Soichi Noguchi are preparing to welcome additional Expedition 23 flight engineers Tracy Caldwell Dyson, Alexander Skvortsov and Mikhail Kornienko (seen l-r):
