'It revealed changes on the Earth's surface that could not have otherwise been as well detected and characterized.' The impact of the multispectral scanner 'has been profound,' Irons says. Irons says Norwood 'earned that self-assurance' and 'stood up for herself to take jobs that paid her equitably with men at a time when that wasn't common.' She was involved in the first five versions of Landsat, with Landsat 5 launching in 1984. 'I never had doubts about the MSS, because I designed it and knew it would work,' she told NASA in 2020. Norwood never doubted that her scanner would workĪfter Landsat 1 launched, the traditional television-like camera that many had preferred failed, and NASA scientists were amazed by the quality of the images from Norwood's scanner. To show that this experimental design would actually work the team took the scanner to Yosemite and took an image of El Capitan. 'There was a lot of skepticism that it would actually work.' The moving mirror 'sounded like a machine gun,' says Jim Irons, an emeritus at NASA Goddard Space Flight Center who worked as a project scientist for Landsat 8 and who met Norwood at the launches of Landsat 8 and 9.
