NASA rocket to paint the sky red, tune in tonight starting at 4:30PM ET (video)


Decades ago, NASA would frequently light up the night sky with chemical trails as part of its measurements of upper atmosphere behavior. While those moments are increasingly rare, we'll get a rare chance to enjoy one of them this evening. The agency's Wallops Flight Facility in Virginia is launching a suborbital rocket that will generate (and test) a pair of trails of red-tinted lithium as it flies above Eastern US coastline -- trails bright enough that large parts of the seaboard may get a first-hand look as the rocket gains altitude. If you fall outside of that range, don't fret. NASA will stream the whole affair starting from 4:30PM Eastern, with a hoped-for takeoff over an hour later. Catch the feed below when the launch is live, and hit the source links for more about the mission itself.
