Mission
SIM Lite would have operated in an Earth-trailing heliocentric orbit. The SIM would have drifted away from Earth at the rate of 0.1 AU per year. At the end of the planned mission, it would have reached a distance of 82 million km from Earth. This would have taken approximately 5½ years. The Sun would have continuously shone on the spacecraft, allowing it to avoid the occultations of target stars and eclipses of the sun that would occur in an Earth orbit.
Had it been launched, SIM would have performed scientific research for five years.

Famous quotes containing the word mission:
“We can come up with a working definition of life, which is what we did for the Viking mission to Mars. We said we could think in terms of a large molecule made up of carbon compounds that can replicate, or make copies of itself, and metabolize food and energy. So that’s the thought: macrocolecule, metabolism, replication.”
—Cyril Ponnamperuma (b. 1923)
“The mission is too important to allow you to jeopardize it.”
—Stanley Kubrick (b. 1928)
“The mission of men there seems to be, like so many busy demons, to drive the forest all out of the country, from every solitary beaver swamp and mountain-side, as soon as possible.”
—Henry David Thoreau (1817–1862)
