First triple REXUS campaign - Flying systems twice on one rocket campaign

Abstract

For the first time in 12 years of REXUS (Rocket Experiments for University Students) history, an on-range reconditioning of flown systems was performed. The Mobile Rocket Base (MORABA) has accomplished an on-range check to reuse two already flown modules during the same campaign. The trigger was the REXUS 24 non-nominal flight. Because of this issue, REXUS 23 was on hold and finally was accepted for launch during the REXUS 23/ 25/ 26 triple campaign. The campaign was executed with just two service and two recovery systems for three rockets. This means a reuse of systems on the same campaign was crucial for a successful threelaunch campaign. Using a new procedure for checking the system condition, DLR MORABA could reduce the costs without affecting the quality of the additional flight, provided the flown systems were in proper shape after their first flight. The aim of this paper is to illustrate the campaign procedure as well as the procedure of on-range checking for the service and recovery module.
