NASA's Roman Telescope Unveils Its Advanced Optics

NASA's Nancy Grace Roman Space Telescope has reached a significant milestone with the delivery of its Optical Telescope Assembly to Goddard Space Flight Center. This assembly, featuring a state-of-the-art primary mirror and nine additional mirrors, will enable the telescope to capture faint infrared light, aiding in the study of dark matter, exoplanets, and galaxy formation. The Roman Telescope, set to launch in 2027, will surpass the Hubble Space Telescope in conducting large-scale sky surveys, thanks to its advanced technology and wide field of view.

"Record Time Calibrator Built for NASA's Roman Telescope to Unlock Universe's Mysteries"

NASA's Nancy Grace Roman Space Telescope, set to launch in 2027, will feature a 300.8-megapixel infrared Wide Field Instrument and a Coronagraph for studying faint objects. The Simplified Relative Calibration System (sRCS) subsystem was recently installed into the WFI's Cold Sensing Module, enabling astronomers to measure the total light output of cosmic objects with extreme accuracy. Roman's mission is to address essential questions concerning dark energy, exoplanets, and infrared astrophysics. The telescope will perform a microlensing survey of the inner Milky Way to find ~2,500 exoplanets and measure light from a billion galaxies. Roman's instruments promise enough precision to measure even weak lensing and see how clumps of dark matter warp the appearance of distant galaxies.
