Summary of our adventure
By DESTINY on April 7, 2019
Our adventure with BEXUS started in May 2018 as a group project gathering five
engineering students from Ecole Polytechnique. Our endorsing professor David
Mimoun - a lecturer at ISAE-Supaero currently working on Insight - told us about
the possibility of building a balloon-borne experiment that we could carry on a
After having defined the most common organisation and project management in such
space missions, we started to work on the BEXUS proposal during Summer 2018.
In August 2018, our team met the ISAE-Supaero team
in Toulouse, France to better define our project. We then understood that our work on stratospheric
infrasounds lay in a bigger project: that is to have a better
understanding of the nature and the propagation of infrasounds in the
atmosphere. The meeting at Supaero had also been the occasion for us to see what
had already been done and to help for a 30-meter-high test flight. The design we
submitted to the selection panel on October 17th was a smaller
version of what we had seen in Toulouse.
After having been selected to be part of the BEXUS programme, we realized that a group
of five was not enough to fulfill the mission: five new members joined the project
in December 2018, and three others the next month. We then clearly defined the requirements
of our mission and started to re-work entirely our initial design. Finally,
we discovered an important part of every space project: documentation.
The preliminary design phase ended after a review that was held during the Student
Training Week in February 2019. We then started the critical design phase: we slightly
modified our design according to the comments of the
BEXUS organizers to improve it, we launched the first tests and we made the first
prototypes. Now, almost one year after the composition of our initial group, we are preparing
for the Critical Design Review.
