This category is rather incomplete, so the real success rate is less than 100%. Placement in this group may seem arbitrary. However, if you don't agree, by all means email me robot@ultimax.com and I might change my policy.
The dearth of Soviet/Russian missions may be due to payloads and purposes of Interkosmos, Prognoz, and especially the generic Kosmos missions not being well documented. Any further information concerning the scientific objectives of the following Kosmos missions, which have been reported to be for astronomical research, would be appreciated: Kosmos-8, -208, -230, -251, -262, -264, -307, and -461.
Because so many Soviet astronomy payloads piggybacked on military satellites, I have decided to also include early US missions such as the Solrad series which also had covert Cold War roles.

Follow-on to Topex, Jason carries Posiedon 2 ocean altimeter.
TIMED is solar-terrestrial probe to study Earth's thermosphere,mesosphere & lower ionosphere, and solar & auroral energy input.
Same launcher, but different orbits counts as two missions.
According to Jonathan's Space Report #458, dated 08Aug2001:
‘Koronas-F, an AUOS-SM type solar-pointing satellite built by Yuzhnoe in Dnepropetrovsk, Ukraine, carries a set of solar physics instruments.
‘There were 11 launches of earth-oriented AUOS-Z satellites between 1976 and 1991, followed by development of the two solar-pointing AUOS-SM satellites AUOS-SM-KI (Koronas-I) and AUOS-SM-KF (Koronas-F), whose names reflect the two research insitutes who were the original principal investigators for the experiment payloads. The I satellite, for the IZMIRAN geophysics institute, was launched in 1994 and reentered earlier this year. The new F satellite carries that designation because the original lead organization was the Lebedev institute known as FIAN in Russian, although it also carries experiments from IZMIRAN and other research centers. ’

Asteroid News: Data from NASA's Near-Earth Asteroid Tracking System NEAT collected from the Mount Haleakala 1 meter telescope on Maui, Hawaii has been used to recalculate the number of Near Earth asteroids. The previous estimate for one km or larger asteroids in this class was between 1,000 and 2,000. The new data has significantly reduced this number to between 500 and 1,000. NASA currently has 322 near-Earth asteroids identified and hopes to have 90 percent of these asteroids identified by 2010. There are 14778 numbered Main Belt asteroids, all of whose orbits are now known. The asteroid tracking system has been on hiatus for the past year, but will be reactivated later this year using an upgraded 1.2-meter telescope. The findings appeared in the January 13 issue of the journal Nature. News courtesy of Dale Gray's Space Frontier Status Report.
