The Planetary Observer program is a cancelled space exploration program designed by NASA to provide cheaper planetary orbiters by utilising Earth-orbiting satellite components and technology, using solar panels for power, and a common spacecraft bus platform for all Planetary Observer-class probes. Only one spacecraft of this class was eventually constructed -- the Mars Observer.

Famous quotes containing the words planetary, observer and/or program:
“We cannot cheat on DNA. We cannot get round photosynthesis. We cannot say I am not going to give a damn about phytoplankton. All these tiny mechanisms provide the preconditions of our planetary life. To say we do not care is to say in the most literal sense that “we choose death.””
—Barbara Ward (1914–1981)
“The possibility of interpretation lies in the identity of the observer with the observed. Each material thing has its celestial side; has its translation, through humanity, into the spiritual and necessary sphere, where it plays a part as indestructible as any other.”
—Ralph Waldo Emerson (1803–1882)
“In former years it was said that at three o’clock in the afternoon all sober persons were rounded up and herded off the grounds, as undesirable. The tradition of insobriety is still carefully preserved.”
—For the State of Vermont, U.S. public relief program (1935-1943)
