MESSENGER Mission News
August 4, 2006 http://messenger.jhuapl.edu/ ______________________________________________________________________________ CORRECTION The August 3, 2006, MESSENGER Mission News incorrectly stated that the spacecraft had traveled “slightly more than 1.275 astronomical units” since its August 3, 2004, launch from Cape Canaveral Air Station, Fla. In fact, since lift off MESSENGER has traveled nearly 1.2 billion miles in its orbit around the Sun. The spacecraft is currently 1.285 astronomical units (AU) distant from the Earth (1 AU equals 93 million miles). To track MESSENGER’s journey, go online to http://messenger.jhuapl.edu/whereis/index.php. _______________________________________________________________________________ MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) is a NASA-sponsored scientific investigation of the planet Mercury and the first space mission designed to orbit the planet closest to the Sun. The MESSENGER spacecraft launched on August 3, 2004, and after flybys of Earth, Venus and Mercury will start a yearlong study of its target planet in March 2011. Dr. Sean C. Solomon, of the Carnegie Institution of Washington, leads the mission as principal investigator. The Johns Hopkins University Applied Physics Laboratory built and operates the MESSENGER spacecraft and manages this Discovery-class mission for NASA. |
