Orbital telescopes function as eyes in the sky that allow astronomers to peer farther…

Unlike the much smaller capsules of the Apollo era, which launched on the tips of rockets and splashed back into the ocean, the jetliner-size shuttle was designed to streak into space using powerful boosters and return to solid ground as a glider.
