The Venus Spectral Rocket (VeSpR)
The goal of this mission was to measure the ratio of deuterium to hydrogen in Venus’ atmosphere by utilizing low cost rocket launch. The mission was launched from White Sands Missile Range, N.M. on 26 November 2013. The spectrograph was mounted inside a sounding rocket that was composed of a first stage Terrier Missile and a second stage Black Brant Mk 1 sounding rocket. The flight reached an elevation of 300 km. and observed Venus for 4 minutes 10 seconds of the 10-minute suborbital flight.

Basic Mission Goal
The spectrograph was a special-purpose instrument that was designed to measure the D/H ratio in the upper atmosphere.
