If your proposal is selected to fly on REXUS or BEXUS, you will be guided through several stages.

Throughout the project, you will keep a record of all information related to your experiment in a document called the ‘Student Experiment Documentation (SED)’. This document must be submitted to the organisers 5 times during the project – it acts as both a review document and a report.

Stage 1 – Preliminary Design

This stage ends with the first submission of the SED and a Preliminary Design Review (PDR).

Stage 2 – Critical Design

This stage ends with the second submission of the SED and a Critical Design Review (CDR)

Stage 3 – Experiment building and testing

Six weeks after the CDR the SED should be submitted again as an Integration Progress Report (IPR) and an expert will visit each experiment team to ensure that integration has begun and discuss any problems and outstanding actions.

Stage 4 – Final Experiment preparations

Shortly before the launch campaign, you will undergo an Experiment Acceptance Review (EAR). The SED must be submitted again with the results of this review before the experiment is integrated onto the rocket or balloon.

Stage 5 – Data analysis and reporting

The SED is updated as a final report with flight performance and experimental results.
