Nancy Grace Roman served as program scientist and lobbied Congress relentlessly to secure funding during the 1970s. Her efforts led to a Senate agreement to fund half the original budget despite initial threats to cut the entire project.
Analysis revealed the outer perimeter of the mirror was too flat by about 2200 nanometers due to an incorrectly assembled null corrector device. This spherical aberration caused light to spread over a radius of more than one arcsecond instead of concentrating within 0.1 arcseconds.
Five Space Shuttle missions repaired and upgraded systems between December 1993 and May 2009. These operations included installing corrective optics packages like COSTAR and replacing failed gyroscopes, solar arrays, and data-handling units.
Researchers announced GN-z11 as the farthest confirmed galaxy in March 2016. The telescope also identified WHL0137-LS nicknamed Earendel as the farthest individual star ever seen in 2022.
