Mini CASSiE is set for a flight on the Horizon!

A new mini CASSiE has been deployed to Queen Mary’s Grammer School in Walsall to take part in an educational balloon flight on Sunday 30th June.


The Mission:

Horizon 2 will use cameras and a sensor array to record atmospheric conditions as it transitions from the ground, through the Troposphere, into the Stratosphere and the region known as ‘near space’.
The project features some cool technology including radio transmitted telemetry data (using a radio antenna constructed out of TV Cable and drinking straws – good for a range of ~500km), a GSM GPS tracker, atmospheric sensors, high definition cameras and a few secret ‘security measures’.

On the day of the launch there will be an online video stream of the launch, live online tracking of Horizon 2 so the public can see where it is throughout the flight and a live twitter feed (@horizonqmgs) all available on the Horizon website (

The Team:

The Project Horizon team is composed of twenty one Queen Mary’s Grammar School pupils ranging in age from 15 to 18 years old. The team raised funds themselves (matching the seed money given by the school), planned the launch, did a lot of the research, built the computer systems, wrote a lot of the software, tested the equipment, built the balloon stack, designed the website, founded the social media presence and handled most of the publicity. The launch is the culmination of one year of research, planning and hard work.

Horizon 2 is also a ‘proof of concept’ and we hope that the Horizon launch platform will fly again in the future, inspiring others to make their dreams a reality and push the boundaries of what schools are supposed to do.

I am very happy that MiniCASSiE (the second) is able to take this journey and I look forward to her safe return and details of her flight!

Good Luck Horizon!
