Boeing Planetary Probe Concept Based on Lunar Orbiter Design

“This is an artist’s impression of how an unmanned would look as it neared Mars before going into a the planet. The Boeing Company has proposed building such a spacecraft, using technology developed during the successful Lunar Orbiter program. It would carry automatic equipment for taking, developing and sending back to Earth close-up photos of our neighboring planets. The spacecraft would operate in orbit for about a year and could be used on missions to Mars or Venus.” Larger image.
