🌌Building and launching Hubble was an enormous engineering challenge.
🔭Hubble's primary mirror had a flaw called spherical aberration, resulting in blurred images.
💡Scientists detected the flaw by comparing actual images to computer simulations.
💪Engineers developed a solution by installing corrective optics on subsequent servicing missions.
📸Hubble's wide field planetary camera, despite the initial flaw, provided breathtaking images of the cosmos.
What was the main problem with Hubble's mirror?
—The mirror had a flaw called spherical aberration, which caused the images to be blurred instead of focused.
How was the flaw in Hubble's mirror detected?
—Scientists compared actual images taken by Hubble to computer simulations, which showed a significant match, indicating spherical aberration was the cause.
How was the issue with Hubble's mirror resolved?
—On subsequent servicing missions, engineers installed corrective optics to compensate for the mirror's flaw, improving the quality of Hubble's images.
What was the significance of Hubble's wide field planetary camera?
—Despite the initial flaw in the mirror, the wide field planetary camera captured breathtaking images of the cosmos, captivating the public and advancing our understanding of the universe.
