Hubble Celebrates 30th Anniversary of Servicing Mission 1 [1]

[]

Date: 2023-12

For three years, Hubble had been the punchline of late-night comics and editorial cartoons: the telescope that couldn’t see straight. Since its deployment in 1990, the telescope had been beaming blurry images back to Earth, the result of a flaw in the shape of its primary mirror. Though the mirror was off by only one-fiftieth the width of a human hair, the error had devastating consequences: the light from the mirror didn’t focus quite right. While the images were still better than those taken from Earth and science was still possible, their quality was not what the world expected.
