A NASA launch in Virginia on Wednesday, May 12, may provide a brief light show for the Eastern half of the U.S., including Michigan.

It was originally planned to launch Saturday, but strong winds caused the launch to be postponed on Saturday-Tuesday.

Here’s the info from NASA’s Keith Koehler:

A mission to explore energy transport in space using a NASA suborbital sounding rocket launching from NASA’s Wallops Flight Facility in Virginia may provide a brief light show for residents of the eastern United States and Bermuda.

The mission is now scheduled for no earlier than 8:06 p.m. EDT with a 40-minute launch window, Wednesday, May 12. Backup launch days run through May 16. The launch may be visible, weather permitting, in much of the eastern United States from the Atlantic coast to the Mississippi River.

A four-stage Black Brant XII rocket will be used for the mission that includes the release of barium vapor that will form two green-violet clouds that may be visible for about 30 seconds. The barium vapor is not harmful to the environment or public health

The mission, called the KiNETic-scale energy and momentum transport eXperiment, or KiNet-X, is designed to study a very fundamental problem in space plasmas, namely, how are energy and momentum transported between different regions of space that are magnetically connected?

The vapor will be released approximately 9 minutes and 30 seconds to around 10 minutes after launch at about 217-249 miles altitude over the Atlantic Ocean and 540-560 miles downrange from Wallops and just north of Bermuda.

Immediately after release of the vapor, the spherical clouds are a mixture of green and violet, but that phase only lasts about 30 seconds when the un-ionized component of the cloud has diffused away. After exposure to sunlight the vapor clouds quickly ionize and take on a violet color.

The ionized portion of the cloud becomes tied to the magnetic field lines and diffuses parallel to the field lines but not perpendicular to it. In the mid-Atlantic region latitudes, the field lines are inclined by about 45 degrees to the horizontal, so the violet clouds stretch out in a slanted orientation and look more like short trails than a cloud. Because the motion of the neutral portion of the clouds is not constrained by the magnetic field lines, they spread out more quickly and become too thin to see with the naked eye much sooner than the ionized component.

The launch will be streamed here, if you want to watch.
