Nancy Grace Roman Space Telescope Mission
The Nancy Grace Roman Space Telescope is a NASA mission scheduled for launch in the mid-2020s. It is designed to study the expansion history of the universe, measure the expansion rate, and search for dark energy. The telescope will also study the chemical composition of galaxies and determine how they have changed over time.
The Roman Telescope will be equipped with a wide-field infrared camera and a spectrograph. The camera will take images of galaxies and clusters of galaxies, while the spectrograph will measure the light from these objects to determine their chemical composition and redshift. The telescope will also be able to observe exoplanets, or planets that orbit stars other than our Sun.
The Roman Telescope is a major scientific undertaking that will help us better understand the universe. It is expected to provide new insights into the expansion history of the universe, the nature of dark energy, and the formation and evolution of galaxies.
History of Nancy Grace Roman Space Telescope
The Nancy Grace Roman Space Telescope (Roman Telescope) is a NASA astrophysics mission planned for launch in mid-2027.
Roman’s development began in 2016 as the Wide-Field Infrared Survey Telescope (WFIRST) with the purpose of addressing the four main mysteries of the 21st century:
- Dark energy and the acceleration of the universe’s expansion

What is a Space Telescope?
A space telescope is a telescope placed in space, outside the disturbing effects of the Earth’s atmosphere. This allows for much clearer and sharper images of celestial objects, as well as the ability to observe objects in infrared, ultraviolet, and other types of light that are blocked by the atmosphere.
Space telescopes are typically placed in orbit around the Earth, but some have also been placed in more distant locations, such as the Lagrange points between the Earth and the Sun. Some of the most famous space telescopes include the Hubble Space Telescope, the Spitzer Space Telescope, and the James Webb Space Telescope.
Types of Space Telescopes
Space telescopes are designed to collect electromagnetic radiation from distant objects in space and study their properties. They come in various types, each tailored to observe specific wavelengths of radiation and astronomical phenomena:
-
Optical Space Telescopes: They capture visible light emitted by celestial objects, offering sharp images of planets, moons, stars, and galaxies. Examples include the Hubble Space Telescope and the James Webb Space Telescope.
-
Infrared Space Telescopes: These telescopes detect infrared radiation, revealing objects obscured by dust or located in cold regions. Examples include the Spitzer Space Telescope and the WISE (Wide-field Infrared Survey Explorer) satellite.
-
Ultraviolet Space Telescopes: They observe ultraviolet radiation, providing insights into the hot and luminous environments of stars and galaxies. Examples include the Galaxy Evolution Explorer and the Swift satellite.
-
X-ray Space Telescopes: They detect X-rays emitted by energetic objects such as black holes and neutron stars. Examples include the Chandra X-ray Observatory and the XMM-Newton satellite.
-
Gamma-ray Space Telescopes: These telescopes study gamma rays, the most energetic form of electromagnetic radiation, emitted by highly active objects like supernovae and pulsars. Examples include the Fermi Gamma-ray Space Telescope and the INTEGRAL satellite.
