GREENBELT, Md., Feb. 18, 2011 /PRNewswire-USNewswire/ -- NASA is inviting its Twitter followers to a daylong event revolving around the sun and Earth's relationship. NASA will randomly select 100 registrants to participate in the Sun-Earth Day Tweetup March 19 at NASA's Goddard Space Flight Center in Greenbelt, Md. Registration opens at noon EST on Tuesday, Feb. 22, and closes at 5 p.m. on Thursday, Feb. 24.
Each year, NASA celebrates Sun-Earth Day near the spring equinox with a series of events that highlight the agency's research and discoveries about our home planet and its star. "Ancient Mysteries, Future Discoveries" is this year's theme for Sun-Earth Day and the Tweetup.
Tweetup participants will be given a personalized tour of the Smithsonian Institution's National Air and Space museum in Washington. They will observe the sun -- weather permitting -- from the museum's public observatory and hear from Smithsonian experts who study the history of astronomy and planetary science. After the Smithsonian visit, the attendees will get a behind-the-scenes look at Goddard's Integration and Test Facility, where engineers ground test instruments and satellites.
Tweetup attendees also will have the opportunity to meet NASA scientists and engineers and be part of a live webcast with the co-hosts of NASA EDGE, an unscripted video podcast that takes a unique look at agency programs and initiatives.
"This is a fantastic opportunity for people who regularly communicate via Twitter about Sun-Earth Day and other NASA programs to meet each other and get direct access to astronomy experts at the Smithsonian and NASA," said Aleya Van Doren, formal education coordinator at Goddard.
