Hands-on project within the ESA Academy

Rexus / Bexus

The REXUS and BEXUS programmes offer opportunities for student experiments to be flown on sounding rockets and stratospheric balloons. Each flight carries a payload consisting solely of student experiments. 

REXUS is an unguided, spin-stabilised, solid-propellant, single stage rocket. The vehicle has a length of about 5.6 m and a diameter of 35.6 cm and the total available mass for student experiments is about 40 kg. Around two minutes of reduced gravity can be obtained if the rocket is despun.

The BEXUS balloon has a volume of 12,000 m³ and a diameter of 14m when filled. The total mass available for the experiments is between 40 and 100 kg. The maximum altitude is around 25 km and the flight duration is 2-5 hours.

For more informations please visit the ESA Website, the REXUS/BEXUS website and the DLR REXUS/BEXUS webpages.

Interested to test your project?

ESA has the capabilities to conduct research on several low gravity platforms and gives the opportunity to students to test their projects in different microgravity conditions. Three platforms are open to students to get results for their thesis or projects. As a direct result of the research conducted during these campaigns, student teams have already presented their results in many theses, at international conferences and/or published papers in renowned scientific journals.

Yearly Opportunities come, please check hereunder the three ongoing ones.

Drop your Thesis - at ZARM Drop Tower you can drop An experiment capsule can be inserted in an evacuated tube and released from 120 meters, providing around 4.74 seconds of microgravity. For more informations please visit:

Fly your Thesis - These parabolic flights take place on the Airbus A300 Zero-G operated and maintained by Novespace from Bordeaux, France. For more informations please visit:

Spin your Thesis -  A Large Diameter Centrifuge (LDC) has recently been developed  by ESA, and can cater to  experiments that  range from 1 to 20 g. With up to 6 gondolas mounted on the long arms and 1 central gondola as a control experiment, this facility can provide, for example, a hypergravity environment for cells and plants, as well as physical science and technological experiments. The programme usually opens a call for proposals once a year in September, which then stays open for three months. For more informations please visit:!_programme

These Projects are just some examples of opportunities that are yearly proposed at ESA. However we encourage all the students to keep tracking of news at the Education web page of ESA where different programs or “hands-on” projects can be proposed.
