The scheduled April launch was scrubbed due to technical problems, but the final preparations are underway for the 25th and final launch, after 19 years in service, of the Space Shuttle Endeavour on Mission STS-134. Launch is scheduled for 1.56pm [BST]. Via the NASAKennedy channel
And a reminder that Endeavour’s final cargo, for the International Space Station, includes a 7-tonne particle physics experiment – the Alpha Magnetic Spectrometer (AMS). And the AMS channel provides this informative Nasa overview of the experiment.
