Are you interested in applying? If so these are the steps to be followed:

  • Form a team of at least 4 people with other university students in an ESA Member and Associate States who would be interested in participating in this programme and are eligible for sponsorship. Try to include people from different disciplines and ensure that the team has a good range of skills addressing the many different tasks involved. For example:
    • A project manager to oversee the project time, technical and financial management.
    • A scientist to define the parameters of the experiment and interpret the measurements.
    • A mechanical engineer to design and build the structure.
    • An electronics engineer to design and manufacture the circuit boards.
    • A software engineer to program the commands and data storage.
    • Someone with good communication skills to develop and execute a successful outreach programme.
  • Download the REXUS and/or BEXUS user manual from the List of documents page and read it to understand what is possible within the constraints of the launch vehicle.
  • Define your project, discuss it with the rest of the team and try to find references in the scientific literature to similar or related research projects.
  • Identify an endorsing professor or academic supervisor whose role will be to supervise the work of your team.
  • Find additional support like institutes, senior scientists and sponsors. You will probably need to use laboratories and specialised tools during the development and testing phases and you will almost certainly need advice when unforeseen problems arise.
  • Consider how much the project will cost and how you will raise the funds for materials, testing facilities and travel of any unsponsored team members.
  • Download the Word format of the Experiment Proposal Form and fill it in.
  • Register on the ESA Education Office's project portal. Your endorsing professor and all the team members should also register on this portal.
  • Access the project portal, apply for the programme and upload the Experiment Proposal Form.

SNSB/ESA proposals will be assessed by a panel of experts. Short-listed experiments will be invited to participate in a selection workshop at ESTEC where a final selection will be made.
