Should you haven’t heard of Virginia Norwood, it’s about time you probably did. An aerospace pioneer whose profession would have been historic even with out its undercurrent of conquer misogynistic discrimination, she invented the Landsat satellite program that screens the Earth’s floor at present. Norwood handed away on March twenty seventh on the age of 96, as reported by NASA and The New York Times.
She achieved all this regardless of vital pushback from the male-dominated trade earlier than and after her rise. Regardless of her apparent expertise, quite a few employers declined to rent her after graduating from the Massachusetts Institute of Expertise. For instance, Sikorsky Plane advised her they might by no means pay her requested wage, equal to the bottom rank within the civil service. One other meals lab she utilized for requested her to vow to not get pregnant as a situation of her employment. (She withdrew her software.) Lastly, the gun producer Remington appreciated her “good” concepts in an interview however advised her they have been hiring a person as an alternative.
Her profession lastly progressed after touchdown jobs with the US Military Sign Corps Laboratories (the place she designed a radar reflector for climate balloons) and Sylvania Digital Protection Labs (the place she arrange the corporate’s first antenna lab). Norwood started working within the Nineteen Fifties as considered one of a small group of girls at Hughes Plane Firm, the place she gained a popularity as a resourceful problem-solver. “She stated, ‘I used to be form of referred to as the one who might resolve unimaginable issues,’” her daughter, Naomi Norwood, advised NASA. “So folks would convey issues to her, even items of different tasks.”
Within the late Sixties, the director of the Geological Survey wished to take pictures of the Earth from house to assist handle land sources; partnering with NASA, a plan was hatched to ship satellites into house. Then engaged on a complicated design crew in Hughes’ house and communications division, Norwood shaped the concept that would outline her legacy. She gathered suggestions from agriculture, meteorology and geology specialists to develop a scanner to file totally different mild and power spectra. Though it used current expertise made for (lower-altitude) agricultural observations, she tailored the tech to fulfill the Geological Survey’s and NASA’s targets.
Nonetheless, she confronted quite a few obstacles in securing a spot for her Multispectral Scanner System (MSS) on the launch satellite tv for pc. It was already hauling an infinite three-camera system developed by RCA utilizing tv tube expertise, which the companies seen as the first imaging supply. To get the MSS onboard, Norwood was tasked with scaling again its dimension to not more than 100 lbs, a major downsizing; the RCA system took up many of the satellite tv for pc’s 4,000 lb. payload.
She lowered the machine to recording solely 4 power bands (down from its unique seven) to make sure it could make the journey as a secondary measurement system. The satellite tv for pc launched on July twenty third, 1972, and the MSS captured its first photographs — of Oklahoma’s Ouachita Mountains — two days later. The outcomes exceeded all expectations, forcing a fast reevaluation of the satellite tv for pc payload’s hierarchy. Norwood’s system carried out higher and was extra dependable than the clunky RCA mission, which induced energy surges and needed to be shut down for good two weeks into the mission.
Landsat rapidly turned the de facto technique of surveying the Earth’s floor. Norwood continued to enhance the system, main the event of Landsat 2, 3, 4 and 5. Landsat 8 and 9, the present variations monitoring the results of local weather change at present, are nonetheless primarily based on her preliminary idea. Her different tasks included main the microwave group in Hughes Plane’s missile lab and designing the ground-control communications gear for NASA’s Surveyor lunar lander.
She reportedly had no problem with the “the mom of Landsat” moniker her friends gave her. “Sure, I prefer it, and it’s apt,” she stated. “I created it, I birthed it, and I fought for it.”
