SESK: Stuff Everyone Should Know · sesk.info/aero-sounding-rocket-short-flights
About how long does a science sounding rocket's payload typically spend in space?
About 5 to 20 minutes, then it falls back on an arc.
- About 5 to 20 minutes ✔
- About 5 to 20 days
- Several years in orbit
Why: Sounding rockets fly up and come straight back down on a parabolic path. They never go into orbit, so the science instruments get only a few minutes above the atmosphere.
Huh, didn't know that: Many payloads are recovered and flown again, which saves money.
Sounding rockets have the shortest vacation ever. Up, quick look, back home.
