ESA communicates between ISS and Robot using Connext DDS

For solving the challenges of building and deploying telerobotic systems for extraterrestrial missions, like system design, systems integration and long-distance communication, the European Space Agency (ESA) opted for the software framework from Real-Time Innovations (RTI). They use RTI Connext DDS for communication and video to demonstrate long-distance object control from aboard the International Space Station (ISS).

What is a near-Earth asteroid?

We often hear from astronomers and other scientists about 'near-earth asteroids' - lumps of rock and metal that orbit through our Solar System, and pass close enough to our planet to pose an impact risk.

Scenes from a ESA spacewalk

As part of ESA’s Expose-R2 project, 46 species of bacteria, fungi and arthropods were delivered by a Progress supply ship to the International Space Station in July 2014. Spacewalking cosmonauts Alexander Skvortsov and Oleg Artemyev attached the package to the outside of the Zvezda module on 18th August 2014, where it stayed until it was retrieved 18 months later.

World-first firing of air-breathing electric thruster

In a world-first, an ESA-led team has built and fired an electric thruster to ingest scarce air molecules from the top of the atmosphere for propellant, opening the way to satellites flying in very low orbits for years on end. ESA’s GOCE gravity-mapper flew as low as 250 km for more than five years thanks to an electric thruster that continuously compensated for air drag. However, its working life was limited by the 40 kg of xenon it c...

Cosmic opportunity for radiation research at ESA

Cosmic radiation is considered the main health hazard to human spaceflight and space exploration of the Moon, Mars and beyond, which is why ESA has made cosmic radiation a focus of its research programme. Radiation poses a risk to the human body in the form of cancer, central nervous system disorders, cardiovascular problems and tissue degeneration.
