In orbit around Lagrange point 1. I would not normally list weather satellites here but this has already taken stunning pictures of Earth and the Moon. Movie clip here.

Spektr-R

Spektr-R, aka RadioAstron is a radio telescope launched by the Russian Astro Space Center. The telescope is used together with ground based radio telescopes and can create a interferometric baseline up to 350 000 km.

Kepler
Mars 7, 2009 | NASA | Kepler website | Paper modelWikipedia

Kepler is a space observatory launched by NASA to discover Earth-like planets orbiting other stars. This telescope has been very successful but is now operating with reduced capacity. After losing two of four reaction wheels (gyroscope like wheels) its unbalanced. It’s now using the sun to balance the telescope. It has since been given a new mission called K2.

WISE
December 14, 2009 | NASA | WISE website | Paper modelWikipedia

WISE is an infrared space telescope in Earth orbit. It started as an all-sky survey but later changed role with a new mission to look for Near Earth Objects. It’s now NEOWISE, part of NASA’s Near Earth Object Program.

Swift is a multi-wavelength space observatory dedicated to the study of gamma-ray bursts.

Spitzer Space Telescope

Even if unmanned missions are more cost effective and safer the Hubble Space Telescope proved the value of manned space flight. Hubble was launched with a faulty mirror and would have been a waste of money if not repaired by a manned mission (STS-61).
