Mission Control Houston has given the green light for the first opportunity to land at Edwards Air Force Base in California, at 8:12 EDT (13:12 in Ireland and UK; 15:12 in Latvia).

The crew will perform a three-minute engine burn at 7:06 EDT (12:06 in Ireland and UK; 14:06 in Latvia) that will deorbit Discovery and put it on track to land in California. THAT IS NOW!

Tom Mangan's Spacecraft Tracking page is interesting to look at, especially now when Discovery is landing.

It combines Google Maps with live updates of spatial positions of Discovery, ISS and Hubble. So you would be able to see Discovery's way towards landing. Nice tool, Tom!
