A look back at the moments that shaped the skies we fly today.
April 24, 1990 — The Hubble Space Telescope Launches
On April 24, 1990, Space Shuttle Discovery roared off the pad at Kennedy Space Center carrying one of the most ambitious scientific instruments ever built: the Hubble Space Telescope. Deployed the following day into low Earth orbit, Hubble would go on to revolutionize our understanding of the universe — capturing images of galaxies billions of light-years away and helping scientists determine the age of the cosmos itself.
It almost didn't work. A flaw in the primary mirror — just 2.2 micrometers off — initially blurred every image. But in 1993, astronauts aboard Space Shuttle Endeavour performed one of the most daring and precise repair missions in spaceflight history, restoring Hubble to full vision.
The lesson? Even the greatest missions hit turbulence. What matters is whether you have the skill — and the guts — to fix it and keep flying.
Eyes on the Horizon
Hubble taught us that the universe is far bigger, older, and more beautiful than we ever imagined. And it took aviators — astronauts trained in the same tradition as every pilot who ever strapped in and pushed the throttle forward — to put those eyes in the sky.
From Hubble to the horizon — at Cleared4Tees, we celebrate the explorers who pushed further than anyone thought possible.
