The Alpha Magnetic Spectrometer has delayed the end of the Space Shuttle Program for about two months, to at least November 2010, so that it can be fitted with a different magnetic that should allow the AMS to last longer when it is attached to the International Space Station.
The NASA STS-134 mission to the International Space Station will be delayed past its July 2010 launch date due to the replacement of a superconducting magnet in the mission's main instrument, the Alpha Magnetic Spectrometer, which will search for the universe's most exotic particles.
