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
