NASA MESSENGER to begin yearlong study of Mercury

By: sclaypoole
With one Earth, two Venus and three Mercury flybys under its belt during the past 6 ½ years, NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft is finally ready to enter Mercury’s orbit on March 17. After executing a 15-minute maneuver, MESSENGER will become the first spacecraft to be placed into Mercury’s orbit and will begin a yearlong campaign to unlock this innermost planet’s mysteries. Mission design and mission operations teams at Johns Hopkins University Applied Physics Laboratory (JHU/APL) have used STK/Astrogator in tandem with other tools throughout the mission. And, in 2008, JHU/APL engineers built a Web-based tool to provide the media and others with quick access to simulated images of Mercury. The interactive “Mercury Flyby Visualization” tool uses STK/Astrogator to define the locations of the spacecraft and Mercury, spacecraft attitude, sensor definition, sensor pointing and timing for each of the targeted science observations and displays it in 3D.
