Wikipedia definition
1. Sounding rocketA sounding rocket, sometimes called a research rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The origin of the term comes from nautical vocabulary, where to sound is to throw a weighted line from a ship into the water to gauge the water's depth. Sounding in the rocket context is equivalent to taking a measurement.
