Here is a primer on the Roman Space Telescope from NASA Goddard \u2013<\/p>\n
The Coronagraph<\/p>\n
One of the two main instruments aboard the Roman Space Telescope is its state-of-the-art Coronagraph. It will help image exoplanets by blocking out the light from its stars, not with mechanical disks, but a system of masks, prisms, detectors and deformable mirrors.<\/p>\n
This technology-demonstrator will showcase the first use of Adaptive Optics and \u201cactive wavefront control\u201d in space, paving the way for future missions such as the Habitable Worlds Observatory.<\/p>\n
Here is a schematic of the complex RST Coronagraph and a diagram of its optical subsystem.<\/a> DM1 and DM2 are the two deformable mirrors, with 48\u00d748 actuators each.<\/p>\n Wide Field Instrument <\/p>\n The primary instrument on the Roman Space Telescope is the Wide Field Instrument (WFI).<\/p>\n It contains a 300-megapixel visible-to-NIR imaging camera and slitless spectrometer. It provides multiband imaging and spectroscopy from the visible to near-infrared (0.48 to 2.30\u00a0\u03bcm) wavelengths.<\/p>\n WFI produces images that match the resolution of the Hubble Space Telescope NIR capabilities, but with a field of view 200x larger.<\/p>\n The WFI will be used to study the nature of dark energy and dark matter, search for exoplanets and for General Astrophysics Surveys.<\/p>\n Below is a pic of the detector array and an illustration of its its wide field of view. https:\/\/roman-docs.stsci.edu\/roman-instruments\/the-wide-field-instrument<\/a><\/p>\n Nancy Grace Roman<\/p>\n Nancy Grace Roman (May 16, 1925 \u2013 December 25, 2018) was an American astronomer who made important contributions to stellar classification and stellar motions. The first female executive at NASA, Roman served as NASA\u2019s first Chief of Astronomy throughout the 1960s and 1970s, establishing her as one of the \u201cvisionary founders of the US civilian space program\u201d.<\/p>\n Roman created NASA\u2019s space astronomy program and is known to many as the \u201cMother of Hubble\u201d for her foundational role in planning the Hubble Space Telescope.<\/p>\n Throughout her career, Roman was an active public speaker and educator, and an advocate for women in the sciences. https:\/\/en.wikipedia.org\/wiki\/Nancy_Grace_Roman<\/a><\/p>\n Epilogue<\/p>\n Here\u2019s a toast to more science and more discoveries about the Universe and our place in it. Somewhere along this journey, hopefully we will find a way to save Earth and ourselves.<\/p>\n Resources<\/p>\n https:\/\/assets.science.nasa.gov\/content\/dam\/science\/missions\/rst\/education\/aug%20Roman%20Press%20Kit-508compliant.pdf<\/a><\/p>\n https:\/\/en.wikipedia.org\/wiki\/Nancy_Grace_Roman_Space_Telescope<\/a><\/p>\n https:\/\/roman-docs.stsci.edu\/<\/a><\/p>\n https:\/\/roman.ipac.caltech.edu\/<\/a><\/p>\n https:\/\/www.youtube.com\/@NASAGoddard\/search<\/a><\/p>\n https:\/\/science.nasa.gov\/mission\/roman-space-telescope\/coronagraph\/<\/a><\/p>\n![\"Coronagraph](\"https:\/\/www.europesays.com\/italy\/wp-content\/uploads\/2026\/08\/image_0312f4.png\")
