Every cycle begins with a Call for Proposals, where university students from ESA member countries or cooperating states can apply. At the selection workshop the invited teams present the experiments to a panel of experts. After this, every selected student team has to work on the preliminary design and the SED (Student Experiment Documentation). This document shall give information to all person responsible and shows the project status. The experts evaluate the progress of the experiment on the basis of the SED, which has to be edited for each review. This phase ends with the Preliminary Design Review (PDR), which is during the Student Training Week.
Thereafter the teams work on the detailed design, which is presented at the Critical Design Review (CDR). After a successful review the design should not be changed, so it can be manufactured.
For the Integration Progress Review (IPR) experts visit each team. At this stage the integration should have been started and subsystem tests made. To ensure that the experiment is ready for the flight, there is the Experiment Acceptance Review (EAR). This takes place shortly before the launch campaign.
After the campaign at the SSC Esrange Space Center each team analyses its data and works on the last version of the SED.

The REXUS (Rocket EXperiments for University Students) is an annual sounding rocket program and
BEXUS (Balloon EXperiments for University Students) an annual stratospheric research balloon program.
