Scientific American electrifies us with news of a cluster of satellites investigating the destructive power of the northern lights:
The Magnetsopheric Multiscale mission, or MMS, consists of four satellites that will study a process called magnetic reconnection: the explosive phenomenon that can send powerful bursts of particles hurtling toward Earth, potentially damaging satellites. But magnetic reconnection is also responsible for the auroras — the northern and southern lights — near Earth’s poles. A new NASA video explains the MMS mission in detail.
…
“[MMS] is going to actually fly in Earth’s magnetosphere, this protective magnetic environment around the Earth,” Jeff Newmark, interim director of NASA’s heliophysics division, said in a Feb. 25 briefing. “We’re using this environment around the Earth as a natural laboratory. Rather than building one on Earth, we’re going to where magnetic reconnection actually occurs in space so we can understand it.”
You can watch the MMS satellite launch Thursday, with NASA’s webcast beginning at 8 p.m. EDT (0000 March 13 GMT). Liftoff is set for 10:44 p.m. EDT (0244 a.m. March 13 GMT) atop an unmanned Atlas V rocket. Today at 1 p.m. EDT (1700 GMT), NASA will hold a science briefing webcast to discuss the mission.
