❓ Frequently Asked Questions
What was the Space Shuttle Program and when did it begin?
NASA's Space Shuttle Program used reusable spacecraft to carry astronauts, deploy satellites, and help build the International Space Station, beginning in 1981.
What are some major achievements of the Space Shuttle era?
It enabled regular satellite deployments and servicing (including the Hubble Space Telescope), construction and maintenance of the ISS, advances in microgravity science, and extensive international collaboration.
What were the two major tragedies of the Space Shuttle program?
The Challenger disaster in 1986 due to an O-ring failure and the Columbia disaster in 2003 caused by debris damage to the thermal protection system during launch and re-entry, both resulting in loss of crew and fleet grounding.
Why was the Space Shuttle Program retired, and what came after?
It ended in 2011 due to safety concerns, rising costs, and aging hardware. NASA shifted to commercial crew partners (e.g., SpaceX and Boeing) for crew transport and relied on other vehicles for cargo while continuing ISS operations.
