When she wants to "chill" for a while, US Air Force SENIOR AIRMAN Cathy Breingan heads for her room. She draws the curtains, turns on the black light and sits under the the stars of her homemade planetarium. "It gives me peace," she said. When her friends walk in, she said they ask, "ooh, where's this girl from?" This image was used in the May 2000 AIRMAN magazine article "Give Vance a Chance". The article is meant to promote a tour at Vance Air Force Base, Oklahoma, as a friendly, family raising type utopia for young Airmen. The base and local community have a very close and productive relationship

CAPE CANAVERAL, Fla. -- At the podium, Russell Romanella, director of International Space Station and Spacecraft Processing at Kennedy Space Center, moderates a panel presenting “Pushing the Limits of Knowledge To Inspire New Generations” during NASA’s Future Forum in Miami. Others on the panel include James Tien, dean of engineering at the University of Miami; Dennis Mills, with UTC/Pratt Whitney Rocketdyne; Jim Halsell, former astronaut; Robert Atlas, director of NOAA's Atlantic Oceanographic and Meteorological Laboratory; and Jack Horkheimer, executive director of the Miami Space Transit Planetarium. The forum focused on how space exploration benefits Florida's economy. The event, which included presentations and panels, was held at the University of Miami's BankUnited Center. Among those participating were NASA Deputy Administrator Shana Dale, astronaut Carl Walz, director of the Advanced Capabilities Division in NASA's Exploration Systems Mission Directorate, and Russell Romanella, director, International Space Station and Spacecraft Processing.

CAPE CANAVERAL, Fla. – Astrophysicist Dr. Neil deGrasse Tyson with the American Museum of Natural History’s Hayden Planetarium in New York, speaks to a group of Tweetup participants at the Kennedy Space Center Visitor Complex in Florida during prelaunch activities for the agency’s Gravity Recovery and Interior Laboratory (GRAIL) mission. Participants toured NASA’s Kennedy Space Center and got a close-up view of Space Launch Complex 17B at Cape Canaveral Air Force Station. The tweeters will share their experiences with followers through the social networking site Twitter. GRAIL will fly twin spacecraft in tandem around the moon to precisely measure and map variations in the moon’s gravitational field. The mission will provide the most accurate global gravity field to date for any planet, including Earth. This detailed information will reveal differences in the density of the moon’s crust and mantle and will help answer fundamental questions about the moon’s internal structure, thermal evolution, and history of collisions with asteroids. The aim is to map the moon’s gravity field so completely that future lunar vehicles can safely navigate anywhere on the moon’s surface. Launch is scheduled for 8:37:06 a.m. EDT Sept. 8.
