The MAIUS Sounding Rocket Missions – Recent Results, Lessons Learned and Future Activities

Kurzfassung

The QUANTUS consortium started activities to perform atom interferometry on a sounding rocket in the year 2011. Three sounding rocket missions (MAIUS-1 to 3) have been planned to demonstrate Bose-Einstein condensation and atom interferometry with rubidium and potassium atoms. Two different payloads MAIUS-A and MAIUS-B are being designed, qualified and integrated in the time frame from 2011 until 2020. The MAIUS-A scientific payload demonstrated the first Bose-Einstein Condensates in Space in the challenging environment aboard a two-staged VSB-30 sounding rocket on the 23rd of January 2017. In order to achieve this ambitious scientific goal the experiment used various sensitive instruments imposing strong requirements on the thermal and mechanical design of the scientific payload. This paper gives a summary of the MAIUS-A and MAIUS-B scientific payload design. Furthermore, the lessons learned from the MAIUS-1 maiden flight as well as the integration and testing activities and their impact on the MAIUS-B scientific payload design are presented. The paper closes with an outlook on future atom interferometry payloads on sounding rockets and beyond.
