On the 15th of Oktober IRISC proposed their experiment to the REXUS/BEXUS committee.


Students from the LuleƄ University of Technology in Kiruna are trying every year to get a project onto a REXUS rocket or a BEXUS balloon. This year multiple teams proposed experiments for both the BEXUS and REXUS program. One of these experiment proposals was from IRISC, our team wanted to bring a near infrared (NIR) camera into the stratosphere to make images of celestial bodies.

This research idea comes from Diego, our team leader. During his internship at the UCSD in San Diego, USA he was discussing balloon-borne telescopes. These telescopes have the opportunity to make research projects more affordable.

The aim of the experiment is to take pictures in the near infrared (NIR) spectrum of astronomical targets outside the solar system for image analysis. The IR camera will be stabilized by a gimbal.

The objectives of the experiment are:

  • Prove the feasibility of a low-cost IR telescope with gimbal stabilization system on a balloon and compare the results with the images acquired by ground-based and space-based telescopes.
  • Study the performance of the IR camera by making multiple pictures with different settings. For instance long exposure of the camera compared to integration of multiple pictures afterwards.
  • Study well-characterised astronomical targets, outside of the solar system that are interesting in the NIR spectrum and comparing our findings to existing data.
  • Verify and study the control system for the gimbal that will be developed during this project.
