HAMMER, High Applicability of Magnetic Motion Experimental Research, is a multinational fundamental research project conducted by students from Luleå University of Technology, LTU, Sweden. The aim of the project is to investigate the applicability of ferrofluids and other fluids, that are susceptible to electro-magnetic fields, in space applications. The project started in October of 2021 and consists of 18 highly motivated students from 7 different nations all over the globe.
The field of ferrofluids and their application in space is an area in which there is currently much exciting new ground being broken. HAMMER aims to contribute to this and develop into continuous projects for this field of study for LTU and their future research. This project aims to evolve from experiments around the manipulation of ferrofluids on the ground to conducting more on various different platforms, Such as microgravity capable drop towers, parabolic flights,
sounding rockets, free falling units etc. These are considered the most practical and informative methods to investigate the fluid behaviour in microgravity environments and space conditions.
The goal of ASTER is to develop a fast, low-cost, and easy to integrate attitude control system for free falling experiments which have been ejected from sounding rockets. ASTER is currently being developed as part of the 13th Cycle of the German-Swedish student programme REXUS/BEXUS and is scheduled to fly on REXUS-30 launched from Esrange Space Center in March 2022.
The project successfully completed its IPR in August 2020, and is now busy integrating and testing their hardware, while looking forward to the Experiment Acceptance Review later on in the year. The proposed design uses three reaction wheels to quickly stabilise or rotate the experiment. The system is also designed to be easily adaptable in order to accommodate future experiments.
The goal of the Multi-Gravity Simulator (MGS) Project is to design and build a classroom sized drop tower. In particular, the project aims at providing a reliable platform for other student projects to conduct experiments in a microgravity environment at a high repetition rate and low cost. Furthermore, the system will be able to simulate other gravity conditions such as the ones of the Moon or Mars. The system will be able to host a payload with a volume of 1U (10cm x 10cm x 10cm) and a mass of up to 2 kg. MGS is planning to move quickly with a small team divided into interdisciplinary departments that will work in coordination: Actuators, Capsule, and Mechanical Structure. The drop tower will serve as a technology demonstrator for a larger scale project to be built at LTU as the next iteration and will be used for educational purposes.
