Sky watchers in the Tri-State Area may get a look at an odd artificial cloud on Saturday night (Sep. 19) after it’s released from the fourth stage of a rocket set for launch from NASA’s Wallops Flight Facility on Virginia’s Atlantic Shore.

Should a rocket blast off on schedule early Tuesday evening, May 5, 2009, from NASA's Wallops Island Flight Facility in Virginia, a potentially spectacular sight might be visible across a wide swath of the U.S. Eastern Seaboard.
