NASA's Swift Gamma-ray Explorer satellite was monitoring Comet Lulin as it closed to 63 Gm of Earth.

The four-seat aircraft was powered by a single Pratt & Whitney Canada PW610F turbofan and was built in secrecy at NASA's Wallops Flight Facility in Virginia by Swift Engineering and Basis.

This nuclear astronomy was predicted in 1969 as a way to confirm explosive nucleosynthesis of the elements, and that prediction played an important role in the planning for NASA's successful Compton Gamma-Ray Observatory.

* The Burst and Transient Source Experiment, ( BATSE ) by NASA's Marshall Space Flight Center searched the sky for gamma ray bursts ( 20 to > 600 keV ) and conducted full sky surveys for long-lived sources.

NASA's planned Space Interferometry Mission ( SIM PlanetQuest ) ( now cancelled ) was to utilize astrometric techniques to detect terrestrial planets orbiting 200 or so of the nearest solar-type stars, and the European Space Agency's GAIA ( due to launch in 2012 ), which will be applying astrometric techniques in its stellar census.

Although this system was not chosen as a primary candidate for the now-canceled Terrestrial Planet Finder, it was a target star for NASA's proposed Space Interferometry Mission to search for Earth-sized planets.

* Jerry Alan Whittredge, dubbed the " Great Astronaut Impersonator ", arrested in 1998 after talking his way into NASA's Mission Control during a Space Mission, being given VIP tours of two Navy bases and receiving information about the space shuttle.

Imaging from NASA's Shuttle Radar Topography Mission STS-99 reveals part of the 180 kilometre ( 112 mi ) diameter ring of the crater ; clustered around the crater's trough are numerous sinkhole s, suggesting a prehistoric oceanic basin in the depression left by the impact.
