STEREO (Solar TErrestrial RElations Observatory) is a Solar observation mission to be launched no earlier than July 22 , 2006 . Two identical spacecraft will be launched into orbits that cause them to (respectively) pull further ahead and fall gradually behind the earth. This will enable Stereoscopic imaging of the Sun and solar phenomena, such as Coronal Mass Ejection s. MISSION PROFILE On orbit outside Earth's orbit. The ahead spacecraft ("A") will encounter the moon again on the same orbital revolution, placing it into a heliocentric orbit inside the Earth's. Spacecraft A will take 347 days to complete one revolution of the sun, with Spacecraft B taking 387 days. They will retreat from the earth by about 22° per earth year. INSTRUMENTATION The spacecraft will carry cameras, particle experiments and radio detectors. The four instruments are called SECCHI (imaging), IMPACT (particles and magnetic fields), PLASTIC (particles), SWAVES (radio waves). EXTERNAL LINKS REFERENCES
