Orbital Study of Mercury

08/09/2005 10:48 AM

Sometimes space travel is difficult. Take the case of the NASA Probe "Messenger". Launched in 2004, it has to use three gravity assists, one by Earth, two by Venus, followed by three flybys to get it into a stable orbit around Mercury. All of this maneuvering will take 7 years. Equipped with color cameras and scientific instruments, Messenger will provide the first new data from Mercury in 30 years and try to answer some outstanding questions from the Mariner 10 mission.
