Scientists have high hopes for a $1.5-billion experiment that might help solve mysteries of the universe, though some have doubts.
Stowed in the cargo hold of space shuttle Endeavour for its final launch Friday is a science experiment that could upend astronomy in ways unparalleled since the Hubble Space Telescope. Or — if it flops — it could end up as a $1.5-billion hood ornament on the International Space Station.
It’s called the Alpha Magnetic Spectrometer. Once it is mounted on the station, scientists hope it will find and analyze high-energy cosmic rays and exotic space particles, including some that could help solve the most profound mysteries of the universe.
