Last month, the Cambridge university Spaceflight society introduced two stages of their Martlet 1 three-stage rocket. After seeing our phone call for rocket builds, they sent in a introduce report. We’re glad they did; it’s an amazing piece of work that screams into the environment quicker than the speed of sound.

The society is designed the three-stage Martlet 1 with the goal of reaching 15km (50,000 feet) over a introduce variety at Ben Armine in Scotland. This introduce was a test of stage separation, meant to work out any type of bugs in the system before going to the full-sized rocket.

When Martlet 1 takes off, it’s 1st stage engine fires for 5 seconds as well as coasts for one more 9 seconds. In the video after the break, the guys expected to hear the pop of the second stage igniting after 14 seconds. The team failed to remember to account for the truth the rocket would be 3km in the air at that time, as well as thanks to the slowness of noise the second stage was heard though the clouds at 25 seconds after launch.

With rockets, barely anything goes precisely as planned, so unfortunately the team only recuperated the bottom half of their rocket. After browsing over 60 square km for the second stage, the guys realized it may be lost to the moors of Scotland. ideally the second stage will turn up soon so the full 3 stage stack can be realized.

Check out the introduce videos after the break.
