The barrel-like shape of the spacecraft itself blocks out unwanted light from the sun. The mirror grants the telescope a 0.281-degree square field of view and sends light to the two main instruments carried by the Roman Space Telescope, the Wide Field Instrument, and the telescope's Coronagraph Instrument. The primary mirror of The Roman Space Telescope is 7.9 ft (2.4 meters) across. The primary mirror of the Roman Space Telescope has a diameter of 7.9 ft (2.4 meters), the same size as the mirror of Hubble but under a quarter of the weight at 410 pounds (186 kilograms). What will the Nancy Grace Roman Space Telescope do?Īccording to the WFIRST-AFTA Science Definition Team Final Report the Roman Space Telescope will weigh 4,166 kilograms (9,184 pounds) at launch and is set to carry a payload of 2,191 kg (4,830 lb). In 2022, NASA estimated the total launch cost of the Roman telescope as $255 million, which includes the launch service and other mission-related costs. The title of the paper detailing an updated Roman telescope that will reach space later this decade was released in 2019, tellingly entitled ' The Wide Field Infrared Survey Telescope: 100 Hubbles for the 2020s." The current and final design of the telescope was introduced in 2015 in the WFIRST-AFTA 2015 Report by the Science Definition Team (SDT) and WFIRST Study Office. Initial designs for the Roman Space Telescope from 2011 suggested it would be equipped with a smaller 4.3 ft (1.3 m) diameter mirror and a single instrument. The development of the Nancy Grace Roman Space Telescope has been handled primarily by NASA's Goddard Space Flight Center, with participation by the Jet Propulsion Laboratory (JPL) and the Infrared Processing and Analysis Center, in Pasadena, California, the Space Telescope Science Institute in Baltimore, and a science team comprised researchers from institutions across the U.S. (Image credit: Daisy Dobrijevic furnished with text supplied by Robert Lea. The Nancy Grace Roman Space Telescope has been a long time in the making. ![]() ![]() Nancy Grace Roman Space Telescope development and cost ![]() "Right now, and all the way up to and after its launch, there will be a lot of opportunities for astronomers to propose their own ideas for Roman, and there are many interesting prospects such as studying stellar mass black holes, exoplanet transit surveys, asteroseismology surveys, and much, much more." Johnson continued. "Roman is planned to teach us a great deal about exoplanets and cosmology, but will have the capability to do so much more," Postdoctoral Fellow at NASA's Jet Propulsion Laboratory, Samson A.

(Image credit: NASA)Īnnouncing the new moniker for WFIRST in 2020 then NASA administrator, Jim Bridenstine said: "It is because of Nancy Grace Roman's leadership and vision that NASA became a pioneer in astrophysics and launched Hubble, the world's most powerful and productive space telescope." ![]() Nancy Grace Roman is best remembered for being the first chief of astronomy in the Office of Space Science at NASA Headquarters, and the first woman to hold an executive position at the space agency.
