SDMB’s auto url feature misparses all links that end with “)”. Which many wiki articles do. Try this [CORONA (satellite) - Wikipedia](https://en.wikipedia.org/wiki/Corona_(satellite)) instead.

None of the Corona systems were sub-orbital. They went up, they made umpteen orbits, taking pictures on some orbits, jettisoned their film, then eventually decayed.
