MASER (MAterial Science Experiment Rocket) programme was started by SSC in 1985, initially in order to increase the flight opportunities for microgravity experiments after the Challenger space shuttle catastrophe. The first launch took place in 1987, providing 7 minutes of microgravity with almost 300 km apogee, and used of a guidance system which is compulsory for such high trajectories. Since the start twelve MASER rockets have been launched from Esrange, with 4-7 experiments per mission. The flights have provided 6-7 minutes of low microgravity levels used as a tool for scientific research in various disciplines – such as fluid science, material science and bio science. Without the presence of gravity, different behaviours of processes and substances can be studied. Moreover, experiments in non-gravity conditions often help scientists to validate their theoretical models.
Within MASER programme, SSC designs and builds experiment modules according to the experiment requirements established by the Science Teams. In this work SSC often subcontracts major tasks to experienced European companies specialised in e.g. optical or mechanical systems.
SSC, with the support of DLR MORABA, also provides the Flight Ticket services for the missions, including payload assembly and tests, service and recovery systems and of course also the launch campaign and the flight.
MASER 13 project was started in 2013 under ESA contract with the preliminary design of the four experiment modules BIM-3, CDIC-3, XRMON-SOL and later also MEDI. With the completion and readiness of all four experiment modules in August 2015, verification tests on integrated payload level will be carried out in SSC’s facilities in Stockholm in September 2015, with launch scheduled for November.

MASER 13 mission is carried out by SSC under ESA contract. The industrial group performing the work consists of SSC in the role of Prime, and the experienced Sub-contractors Airbus DS in Bremen, RUAG Space Systems in Nyon, DTM in Modena, Techno System developments in Pozzuoli, Naples as well as Lambda-X in Nivelles, Brussels, who all have developed major parts of the experiment modules.
DLR MORABA in Oberfaffenhofen, Munich, contribute largely to the Flight Ticket part of the mission, such as rocket motor systems, recovery system, rate control system, flight analysis and ground telemetry system.
