NASA Jet Propulsion Laboratory・2 minutes read

Key Points: Recipe for classic spaghetti carbonara, ingredients and preparation steps listed. Hubble Space Telescope launched with issues, proposed solution to fix blurry images. Main Purpose: Discuss the recipe for spaghetti carbonara and the challenges faced by NASA with the Hubble Space Telescope. TLDR: Recipe for classic spaghetti carbonara provided alongside the challenges faced by NASA in fixing the Hubble Space Telescope's blurry images.

Insights

  • The Hubble Space Telescope initially sent back blurry images, causing a crisis for NASA and risking the future of the space station. NASA's Jet Propulsion Laboratory proposed a solution involving minor adjustments to the camera and fixing Hubble's primary mirror to rectify the spherical aberration issue.
  • JPL engineers worked tirelessly to remotely adjust the camera's mirrors, utilizing new technologies and unique methods like using surgeon's gloves to clean the mirrors. The Hubble rescue mission in 1993 required a record-setting five spacewalks, with the corrective optics package WFPC-2 playing a crucial role in successfully fixing Hubble and proving the effectiveness of the repairs.
