| THEMIS Launches!

Taking multitasking to new heights, NASA launched the five THEMIS
satellites aboard a single Delta II rocket from Cape Canaveral Air
Force Station in Florida at 6:01 p.m. EST. Racing into space on the
flaming power of three rocket stages and nine solid rocket motors, the
THEMIS satellites will soon disperse around Earth to monitor auroras
like the Northern Lights. NASA is undertaking the mission to
investigate what causes auroras in the Earth's atmosphere to change in
appearance and dissipate. Discovering why the light of auroras can
fluctuate and fade will provide scientists with important details on
how the planet's protective magnetosphere works and on the sun-Earth
connection. The Mission THEMIS is a
mission to investigate what causes auroras in the Earth's atmosphere to
dramatically change from slowly shimmering waves of light to wildly
shifting streaks of color. Discovering what causes auroras to change
will provide scientists with important details on how the planet's
magnetosphere works and the important Sun-Earth connection. + Read more
