The Space Shuttle Endeavour on its final Mission brings a sense of sadness, and of inevitability because I don't like ends nearly as well as beginnings. As a bit of a science nerd, I enjoyed the shuttle missions and seeing the horizons of mankind expand. It doesn't seem that we're going to be invested in space in the coming years as completely as we were in those preceding.
On Thursday, the two orbiting crews will attach the $2 billion Alpha Magnetic Spectrometer to the space station. The instrument will seek out invisible dark matter as well as antimatter; whether any of this is found or not, the results will help explain what the universe is made of and how it formed.
It is the 12th and final visit by Endeavour to the space station. After this mission, Endeavour will be de-commissioned and sent to the California Science Center.
