If the shuttle Endeavour meets its scheduled launch time of 20:47 BST on the 29th, there may be a chance for spacewatchers in southern Britain to spot it less than 20 minutes later as it crosses the brightly twilit SSW sky as seen from S England. Flying close by, shining with an orange hue, should be the external fuel tank, separated from the shuttle and destined to re-enter and burn up in the atmosphere further around the orbit. Endeavour's flight to the International Space Station is expected to be the penultimate shuttle flight.
The ISS is making spectacularly bright transits in our evening sky. Asterisks in our BST predictions flag the directions in which it fades into the Earth's shadow.
