PARIS (ESA PR) — The most sophisticated laser communication network ever designed has gained its second satellite.

The European Data Relay System (EDRS) was built to accelerate the flow of information from Earth-observation satellites to people on the ground.

The second satellite in the network, EDRS-C, has now passed its user commissioning review and entered into full service.

PARIS (ESA) — The second node in the most sophisticated laser communication network ever designed is ready to go into service.

Dubbed the “SpaceDataHighway”, the European Data Relay System (EDRS) helps Earth-observing satellites to transmit large quantities of potentially life-saving data to Europe in near-real time.

  • 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.

BERN, Switzerland (RUAG Space PR) — The European Data Relay System (EDRS), dubbed the “SpaceDataHighway”, uses innovative laser technology to dramatically cut the time needed for Earth observation satellites to deliver information to the ground. The second satellite to join the sister satellite already in orbit is due for launch on 6 August.

The “brain” (onboard computer) of the latest satellite, called EDRS-C, was delivered from RUAG Space to the satellite builder OHB System AG. The onboard computer controls and monitors the payload of the satellite and many other subsystems.

PARIS, 20 July 2018 (ESA PR) — A new ESA-led project is investigating the ways that 3D printing could be used to create and run a habitat on the Moon. Everything from building materials to solar panels, equipment and tools to clothes, even nutrients and food ingredients can potentially be 3D printed. But if you were headed to the Moon, what would you want to 3D print, to turn a lunar base into a place that feels like home? Tell us your idea, to win a chance of actually getting it printed.
