Space Telescope Science Institute supports fellows undertaking research associated with all missions within the Cosmic Origins theme: the Herschel Space Observatory, Hubble Space Telescope (HST), James Webb Space Telescope (JWST), Stratospheric Observatory for Infrared Astronomy (SOFIA), and the Spitzer Space Telescope. The research may be theoretical, observational, or instrumental. Each year, since HST's launch in 1990, 8 to 12 fellowships are awarded; from 2009 it hovers about 16. STScI also sponsors a summer student intern program that allows talented undergraduate students from around the world to work with the Institute's scientific staff, providing these students with hands-on experience in state-of-the-art astronomical research.

Space Surveillance Telescope Space Surveillance Telescope The Space Surveillance Telescope is a telescope for detecting and tracking orbital debris. It has a 3.5 meter (138″) aperture mirror and came online in 2011. Two noted design features include Mersenne-Schmidt type optics and a curved CCD. In 2010s the telescope, which was in New Mexico, United States, was transferred to United States Air Force Space Command and moved to Australia. The discovery and tracking of space debris is noted as a growing problem in the 21st century. One problem is that among the 20-30 thousand large objects in orbit that are tracked, and an estimated
