Mission overview

Mission Overview

  • We will calculate the speed of sound as our satellite rises to an altitude of 30km

  • We hypothesise that the speed of sound will change in relation to the changes in temperature and pressure

  • This data could be useful for scientists calculating the density of the atmosphere of another planet

    Consistent data, but worse with time


    Calibration wind test

    Calibration/Wind Test

    • Microphone

    • Filtering

      • Passive - threshold

      • Active - stray data

    • Precision of the clock

      • Percent error due to clock

    • Heights

    • Drop angles


    Kick whip test

    Kick/Whip Test

    • minimal damage


    Expected results

    Expected Results

    • We expect to record accurate data from all sensors

    • Hope to see predicted trends in this data

    • From this flight, we hope to see how a change in altitude changes the speed of sound


    Biggest worries

    Biggest Worries

    • The microphone won't pick up the sound from the speakers

    • The carbon fiber tubes snap.

    • The camera lense fogs up.
