  • Important milestone – successful completion of the 10th measurement campaign with the PK-4 plasma crystal laboratory on the ISS.
  • For the first time, the German Space Operations Center has taken over the scientific support of the PK experiments.
  • COVID-19 protection measures – DLR scientists from Oberpfaffenhofen maintain contact with the PK-4 Control Centre in Toulouse and the ISS.
  • Unique insights using PK-4 – plasma crystals can form in microgravity. The plasma particles behave like atoms and can be observed individually with the naked eye.

OBERFAFFENHOFEN, Germany (DLR PR) — Under normal circumstances, the researchers would have gone to Toulouse, as only from there can they control the PK-4 plasma crystal laboratory, which has been on board the International Space Station (ISS) since 2015. However, the Coronavirus pandemic has made travelling from Oberpfaffenhofen to the CADMOS Control Centre in France impossible. The experiments under microgravity conditions, which had taken months of preparation, were at risk of being cancelled.

ESA Reports Promising Progress for ExoMars Parachutes

A series of clips from different angles and at different speeds showing parachute extraction tests using a NASA/JPL test rig powered by compressed air.  The lid of the parachute assembly is pulled along a suspended cable at high speed while the end of the assembly is fixed to a wall. When the release mechanism is activated, the parachute bag is pulled away from the parachute at the target speed, mimicking the extraction as it will be on Mars. At the highest speeds, the tests enable the extraction to take place at more than 200 km/h.

PARIS (ESA PR) — A series of ground-based tests designed to check the extraction of the ExoMars 2020 mission’s parachutes from their bags have started successfully with promising results to keep the mission on track for next year’s launch.

Landing on Mars is a high-risk endeavour with no room for error. In just six minutes, a descent module with its precious cargo cocooned inside has to slow from around 21 000 km/h at the top of the planet’s atmosphere, to a soft landing at the surface controlled by the lander’s propulsion system.

Plasma Crystal Research Conducted on the ISS

  • Plasma research on the ISS – Cosmonaut Alexander Skvortsov will be carrying out a new series of experiments from 10 to 16 November 2019
  • Important knowledge for tomorrow – the plasma crystal laboratory PK-4 provides insights into fundamental physical processes
  • Plasma is ionised gas and is considered to be the fourth state of matter in addition to solids, liquids and gases. Complex plasmas are formed when dust particles are present in the neutral gas

TOULOUSE, France (DLR PR) — More plasma research is being conducted on the International Space Station (ISS). From 10 to 16 November 2019, the Russian cosmonaut Alexander Skvortsov will be carrying out a new series of experiments with the PK-4 plasma crystal laboratory. Under the direction of scientists from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), Skvortsov will record how microparticles move through a neon plasma in microgravity, forming structures and thus providing insights into basic physical processes.

WASHINGTON, DC (NASA PR) — NASA has selected nine grant proposals for space biology research experiments, the results of which will contribute to the understanding of health risks humans will experience in deep space, including exploration at the Moon through the Artemis program and future missions to Mars. Selected investigators will have an opportunity to conduct rodent experiments to be flown on a biosatellite mission, known as Bion-M2, with the Russian space agency Roscosmos.
