There were five space shuttle missions that launched before Challenger, starting with Columbia in April 1981.
Space shuttles were designed for multiple missions, typically flying around 25-30 missions before being retired. NASA had multiple space shuttles in its fleet, such as Atlantis, Discovery, Endeavour, and Columbia, which were used for various missions before being replaced.
Multiple space shuttle orbiter vehicles are necessary to meet launch schedules. While reusable, each orbiter requires 6-9 months of refurbishment and processing before it is ready for the next mission. NASA refers to this as the "flow"
Space shuttle Endeavour has not crashed. The shuttles Challenger and Columbia disintegrated in January 1986 and February 2003 respectively.
There were six space shuttles built between the late 70s and early 1990s. Their names are: Enterprise, Columbia, Challenger, Discovery,Atlantis and Endeavor. The Enterprise flew several times on top of a modified Boeing 747 Jumbo Jet, and did glidding tests in the 70s, but never went into space. This tests lead to discovering problems with heat tiles falling off that were resolved in later shuttles. Both the Challenger and the Columbia were lost in accidents, the Challenger as it took off from Florida, the Columbia as it re-entered the atmosphere.

The space shuttles were designed to fly A maximum of 100 missions each, but every orbiter will have been destroyed or retired before reaching even 70 missions.

No. Well it depends how you phrase your question, he was famous before his trip to the moon by all the test drives on rockets and shuttles he did. So he went to the moon after he was famous.

The reptile that have to be cleared from the runway before they can land the shuttles at the Kennedy Space Center are female turtles. They will come on shore during the night to lay their eggs.

Space craft prior to the space shuttles were one-time-use vehicles. The space shuttles were made to be multiple use vehicles.
Space shuttles operate primarily in the thermosphere, a layer of Earth's atmosphere that extends from about 80 kilometers (50 miles) to 600 kilometers (370 miles) above the surface. During launch, they pass through the troposphere and stratosphere before reaching the thermosphere, where they achieve low Earth orbit. In this region, they can travel at high speeds and conduct various missions, including satellite deployment and International Space Station resupply.
Discovery has not been destroyed, but is still undertaking missions. Only the space shuttle Challenger (January 28, 1986) and Columbia ( February 1, 2003) have been destroyed in accidents.
