ARTEC

 ARTEC (AeRogeI TEchnoIogy for Cast alloys) enables directional solidification experiments under high cooling rates with cast alloys. Besides a fast freezing of the sample conserving the solidified microstructure a better theoretical understanding of the influence of a sudden change of solidification velocity on microstructure formation is obtained. Carrying out experiments in microgravity gives access to purely diffusive solidification conditions. Hence, convection free-growth can be compared with growth subject to natural (earth) and/or forced-convection (earth and space). Furthermore, alloys with high density differences in their alloy components, and, hence, also between the primary solidifying phase and the surrounding liquid can be studied without the negative influence of fluid-flow or macrosegregation being present. The results of this experiment may contribute to solidification modeling and provides information for foundry industry to improve quality and deliveries.

MARS

The experiment uses selective laser sintering of metals in microgravity. In this manufacturing process thin layers of a metallic powder are applied and selectively sintered to the printed body by laser irradiation. Layering and sintering are performed alternating until the product is complete. Besides space-proofing this technology in general, the most challenging task in a Iow- or microgravity environment is to handle the raw metal powder properly and to apply a high quality powder layer. With fewer or even no gravity there is no driving force for the powder to form dense packed layer until sintering has been completed. The aim of the experiment is to validate the 'assisted deposition' of powder layers in microgravity, using different metal powders; with special interest to print parts from metallic glasses.

RAMSES III

RAMSES (Random Motion of Microswimmers - Experiment in Space) is designed to investigate the collective motion of artificial microswimmers in three dimensions. Ensembles of artificial microswimmers represent situations out of thermal equilibrium, and as such they can be used to verify and calibrate statistical out-of-equilibrium theories. The microswimmers used for RAMSES are realized by coating one hemisphere of glass particles (d≈2µm) with a thin layer of carbon. This carbon-coated surface heats up with illumination, which is in suspension used to generate thrust on these particles. The specific combination of particle material and suspension fluid required for generating active swimming prevents density-matching of the particles. and present studies on active swimming are restricted to two-dimensional systems. For RAMSES the required sample cells, illumination and diagnostics are integrated in a sounding rocket module to facilitate studies without gravitational settling.

MExA

apex Mk.II Science Camera Platform (SCP) and apex Mk.III Student Experiment Sensorboard (SES) are the successors of the acknowledged advanced processors, encryption and security experiment (apex) run by the DLR Microgravity User Support Center (MUSC). SES is a 55x55 mm sized Interface Element, providing an Espressif ESP32 Micro Controller Unit (MCU), Micro SD Card es well as an UART, I2C and SPI Interface. Using SES, students are able to quickly implement their own µG experiments. Connection to the Service Module interfaces (the three rocket signals (Lift Off, Start/Stop of Data Sampling, Start/Stop of Experiment), the Telemetry / Telecommand (TM/TC) Interface, es well as the power supply) is realized by SES end provided to the user. This system will be equipped with an example sensor network and tested during MAPHEUS 10. SCP has been developed as cooperation between Nico Maas from the Microgravity Support Center (MUSC) of DLR Space Operations and Astronaut Training and Dr. Jens Hauslage from the Department of Gravity Biology of the DLR Institute of Aerospace Medicine. It provides an augmented HD Camera, which can be used to monitor the effects of microgravity on biological samples using the attached microscope.
The M-42 system and the EAD system shall monitor the radiation environment during the mission. In addition, the mission will enable DLR-ME-SBA to test the in-built accelerometer of the M 42 and the EAD system which is able to detect the launch and subsequently start the radiation measurement sequence of the M-42 system. All measured radiation data will be stored in the in-built redundant memory with a storage interval of 10 seconds to fully capture the radiation environment and its changes over the mission.
