• On January 29, 2022, the DLR sounding rocket MAPHEUS-9 brought four experiments into weightlessness for around six minutes.
• The rocket, weighing 1.7 tons, took off from the ESRANGE launch site in northern Sweden and reached an altitude of 254 kilometers.
• Experiments from the fields of materials research and manufacturing technology, granulate physics and gravitational biology were also on board.

KIRUNA, Sweden (DLR PR) — Plate animals usually like it a little warmer. For science, the simplest multicellular animal in the world ended up in northern Sweden – and from there into weightlessness for a short time. On January 29, 2022, the marine organisms were successfully lifted off the rocket launch site on board the MAPHEUS-9 sounding rocket operated by the German Aerospace Center (DLR) at ESRANGE (European Space and Sounding Rocket Range). Three other experiments from the fields of physics, materials research and manufacturing technology also enjoyed six minutes and ten seconds in zero gravity.

• The plasma crystal experiments are one of the first and most successful research projects on the ISS.
• The first long-term tests under weightlessness started on March 3, 2001: They provide insights into physical processes at the atomic level.
• ISS astronauts are always part of the plasma research team, including Thomas Reiter during his Astrolab mission.
• From 22-29. The next experiments on board the ISS will run on March 2021.

COLOGNE, Germany (DLR) — For 20 years they have been a reliable source of new insights into physics: the plasma crystal experiments on board the International Space Station ISS. Basic knowledge for the textbooks of the future is the main goal of this research. Various applications can be derived from the knowledge gained, in particular in the fields of medicine, environmental protection, space travel as well as semiconductor and microchip technologies. 

By means of technology transfers, plasma research also opens up new fields of application, based for example on the development of miniaturized laboratory systems suitable for space travel. The first ISS crew already had plasma research on their agenda and on March 3, 2001 the starting shot was given for the first long-term tests under weightlessness. The current crew will now carry out the latest series of experiments at the end of March.
