A space telescope or space observatory is a telescope in outer space used to observe astronomical objects. Suggested by Lyman Spitzer in 1946, the first operational telescopes were the American Orbiting Astronomical Observatory, OAO-2 launched in 1968, and the Soviet Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971. Space telescopes avoid the filtering and distortion (scintillation) of electromagnetic radiation which they observe, and avoid light pollution which ground-based observatories encounter. They are divided into two types: Satellites which map the entire sky, and satellites which focus on selected astronomical objects or parts of the sky and beyond. Space telescopes are distinct from Earth imaging satellites, which point toward Earth for satellite imaging, applied for weather analysis, espionage, and other types of information gathering.
The Hubble Space Telescope is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft.
The Space Telescope Science Institute (STScI) is the science operations center for the Hubble Space Telescope (HST), science operations and mission operations center for the James Webb Space Telescope (JWST), and science operations center for the Nancy Grace Roman Space Telescope. STScI was established in 1981 as a community-based science center that is operated for NASA by the Association of Universities for Research in Astronomy (AURA). STScI's offices are located on the Johns Hopkins University Homewood Campus and in the Rotunda building in Baltimore, Maryland.
The Spitzer Space Telescope, formerly the Space Infrared Telescope Facility (SIRTF), was an infrared space telescope launched in 2003. Operations ended on 30 January 2020. Spitzer was the third space telescope dedicated to infrared astronomy, following IRAS (1983) and ISO (1995–1998). It was the first spacecraft to use an Earth-trailing orbit, later used by the Kepler planet-finder.
The Goddard Space Flight Center (GSFC) is a major NASA space research laboratory located approximately 6.5 miles (10.5 km) northeast of Washington, D.C. in Greenbelt, Maryland, United States. Established on May 1, 1959 as NASA's first space flight center, GSFC employs approximately 10,000 civil servants and contractors. Named in recognition of American rocket propulsion pioneer Robert H. Goddard, it is one of ten major NASA field centers. GSFC is partially within the former Goddard census-designated place; it has a Greenbelt mailing address.
The SETI Institute is a not-for-profit research organization incorporated in 1984 whose mission is to explore, understand, and explain the origin and nature of life in the universe, and to use this knowledge to inspire and guide present and future generations, sharing knowledge with the public, the press, and the government. SETI stands for the "search for extraterrestrial intelligence".
NASA's series of Great Observatories satellites are four large, powerful space-based astronomical telescopes launched between 1990 and 2003. They were built with different technology to examine specific wavelength/energy regions of the electromagnetic spectrum: gamma rays, X-rays, visible and ultraviolet light, and infrared light.
Philip Cary Plait, also known as The Bad Astronomer, is an American astronomer, skeptic, and popular science blogger. Plait has worked as part of the Hubble Space Telescope team, images and spectra of astronomical objects, as well as engaging in public outreach advocacy for NASA missions. He has written three books, Bad Astronomy, Death from the Skies, and Under Alien Skies. He has also appeared in several science documentaries, including How the Universe Works on the Discovery Channel. From August 2008 through 2009, he served as president of the James Randi Educational Foundation. Additionally, he wrote and hosted episodes of Crash Course Astronomy, which aired its last episode in 2016.
The Infrared Processing and Analysis Center (IPAC) provides science operations, data management, data archives and community support for astronomy and planetary science missions. IPAC has a historical emphasis on infrared-submillimeter astronomy and exoplanet science. IPAC has supported NASA, NSF and privately funded projects and missions. It is located on the campus of the California Institute of Technology in Pasadena, California.
Doris Daou is a Lebanese-born astronomer from Canada who was formerly the Director for Education and Public Outreach of the NASA Lunar Science Institute and the Associate Director of the NASA Solar System Exploration Research Virtual Institute (SSERVI), and is currently the program contact for NASA's "Small Innovative Missions for Planetary Exploration (SIMPLEx)".
Nancy Grace Roman was an American astronomer who made important contributions to stellar classification and motions. The first female executive at NASA, Roman served as NASA's first Chief of Astronomy throughout the 1960s and 1970s, establishing her as one of the "visionary founders of the US civilian space program". She created NASA's space astronomy program and is known to many as the "Mother of Hubble" for her foundational role in planning the Hubble Space Telescope. Throughout her career, Roman was also an active public speaker and educator, and an advocate for women in the sciences.
Edward L. (Ned) Wright is an American astrophysicist and cosmologist, well known for his achievements in the COBE, WISE, and WMAP projects and as a strong Big Bang proponent in web tutorials on cosmology and theory of relativity.

Dr. Kimberly A. Weaver is an American astrophysics astronomer and professor. She has worked with NASA on several research projects. She is often seen on television programs about astronomy. She is an expert in the area of x-ray astronomy.
IRrelevant Astronomy is a web series produced by NASA's Spitzer Space Telescope. Each episode explains a general science concept or reveals science news relevant to Spitzer. The "IR" in the title stands for "infrared", making the title refer to "infrared-relevant astronomy." The first episode launched on January 15, 2008 on the Spitzer Space Telescope website.
Beth A. Brown was a NASA astrophysicist with a research focus on X-ray observations of elliptical galaxies and black holes. She earned a Ph.D. in Astronomy from the University of Michigan in 1998, becoming the first African-American woman to do so.
Elisa Victoria Quintana is a scientist working in the field of astronomy and planetary science at NASA Goddard Space Flight Center. Her research focuses the detection and characterization of exoplanets in addition to studying how they form. She is best known for the detection of Kepler 186f, the first Earth-sized planet found in the habitable zone of a star other than the Sun.

Rieke was also involved with several infrared ground-based observatories, including the MMT Observatory in Arizona. She was vice chair for Program Prioritization of the Astro2010 Decadal Survey Committee, "New Worlds, New Horizons". Marcia Rieke is considered by many to be one of the "founding mothers" of infrared astronomy, along with Judith Pipher.
