About this episode

This episode discusses the launch of the Hubble Space Telescope and its initial flaws, followed by the successful repair mission that transformed its capabilities.

# This is your Astronomy Tonight podcast. Good evening, stargazers! Today we're celebrating a truly monumental moment in space exploration history—March 22nd, the day the Hubble Space Telescope was launched into orbit in 1990! Now, I know what you might be thinking: "Wait, wasn't Hubble supposed to be perfect right out of the box?" Well, here's where the drama comes in. When Hubble first opened its eyes to the cosmos, astronomers were absolutely devastated to discover that its primary mirror had a manufacturing flaw—a spherical aberration about 2 micrometers off. It sounds tiny, but in the world of space telescopes, that's like trying to read a newspaper from across town while wearing the wrong prescription glasses! But here's the beautiful part of this story: humanity didn't give up. In 1993, astronauts conducted an incredibly daring repair mission, installing corrective optics during a spacewalk—essentially giving Hubble cosmic glasses. From that moment on, the telescope transformed into the greatest eye humanity has ever had on the universe, revolutionizing our understanding of everything from distant galaxies to the age of the cosmos itself. Over three decades later, Hubble…
