MIDNIGHT ROCKET PLUMES: On Friday, March 23rd, between midnight and 3 am EDT, NASA plans a rapid-fire launch of five sounding rockets from the Wallops Flight Facility in Virginia. The rockets will deliver a chemical tracer to the upper reaches of Earth's atmosphere, forming milky white plumes that reveal high-speed winds at the edge of space. The display should be visible to the naked eye from coastal areas between South Carolina and New Jersey.
