About team ASTER
Project ASTER (Attitude STabilized free falling ExpeRiment) aims to develop a high performance, low-cost and easy to integrate attitude control system for free falling experiments ejected from sounding rockets.
ASTER team is composed of student of LTU, Luleå University of Technology, in Sweden.
This project is part of the REXUS/BEXUS program and is realized under an agreement between the German Aerospace Center (DLR) and the Swedish National Space Agency (SNSA).
About the experiment
This Open-Design solution utilises three electrically-powered reaction wheels to stabilise and orientate the free falling unit in three axes in a reduced gravity environment.
The system shall be compact to ensure sucient space to accommodate the payload of future missions. Additionally, the stabilisation shall be performed rapidly, in order to increase the available time for experiments after the successful stabilisation. Lastly, the solution should be able to perform predefined slewing manoeuvres to be adaptable to a wider range of applications.
The REXUS/BEXUS programme is a student program realised under a bilateral Agency Agreement between the German Aerospace Center (DLR) and the Swedish National Space Agency (SNSA). The Swedish share of the payload has been made available to students from other European countries through the collaboration with the European Space Agency (ESA).
Experts from DLR, SSC, ZARM and ESA provide technical support to the student teams throughout the project. EuroLaunch, the cooperation between the Esrange Space Center of SSC and the Mobile Rocket Base (MORABA) of DLR, is responsible for the campaign management and operations of the launch vehicles.
