The space shuttle is reaching the end of its life with only a couple of missions left. One of those will be to deliver and attach a new cosmic ray experiment to the space station. AMS has been developed at CERN and was recently modified to replace its superconducting magnet with a longer life permanent magnet so that it can continue for the extended life of the ISS.
This picture was taken in May as the space station passed in front of the Sun as Atlantis approached. It was captured by astrophotographer Thierry Legault.
