APOD 4.5

18 May 2011 - The Last Launch of Space Shuttle Endeavor

On Monday, the shuttle Endeavor launched for the last time. It carried six astronauts and docked with the International Space Station. They are going to deliver an apparatus that can detect antimatter, dark matter, and strangelets called the Alpha Magnetic Spectrometer. Dark matter is any matter whose existence can be deduced based on gravitational effects on the surroundings but cannot be "seen" by usual means. Antimatter is a counterpart to normal matter (much less abundant than it) and when combined with matter, causes fulminating cataclysms. Strangelets are objects that have strange combinations of up and down quarks. The last shuttle launch will occur in mid-July, and I will endeavor to go see it.
