ExoMars - Moving on Mars
The ExoMars mission will see Rosalind Franklin the rover and its surface platform Kazachok land on the Red Planet in 2021.
ExoMars rover science laboratory fitted
The ExoMars rover’s Analytical Laboratory Drawer (ALD) was integrated into the rover at Airbus, Stevenage, UK in May 2019. The video is shown at 18 times real speed; in reality the sequence of events took around 11.5 minutes.
Preserving data for our future
Satellites provide vast quantities of data. While these data are processed and used by scientists and analysts to understand and monitor Earth, they are also carefully archived.
World Water Day: what's space got to do with it?
For World Water Day ESA take a look at ways that space can help this global challenge.
ExoMars Rover: from concept to reality
The second part of the ExoMars programme is ongoing. In Stevenage, UK, a rover is being built that will carry a drill and a suite of instruments dedicated to exobiology and geochemistry research.
European Student Earth Orbiter ready for launch
The European Student Earth Orbiter (ESEO) is an educational micro-satellite, which involved European university students during the whole project life cycle.
Horizons mission - preparing for a spacewalk
Known to the crew as an EVA (extravehicular activity), each spacewalk provides a valuable opportunity to carry out repairs, test new equipment and even perform science experiments beyond the confines of a spacecraft.
The mission that brought an asteroid down to Earth
Some of the rarest, most precious materials on Earth originated very, very far away, and are only available to us now because of the Hayabusa mission of JAXA, the Japan Aerospace Exploration Agency.
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...
How do we take space debris out of orbit?
Don’t be scared of space debris. ESA’s Clean Space initiative is carrying out preparatory activities to build a test mission to take a single, large and heavy item of debris out of orbit.
Space... clean and untouched?
The ESA’s Clean Space initiative works hard to keep space safe and clean for future generations. Its three main objectives are presented in this video.
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.
Tracking the solar eruption through the solar system
Animation visualising the propagation of a coronal mass ejection leaving the Sun on 14th October 2014 and highlighting the speed at which it reached various spacecraft over the following days, weeks and months (not to scale).
LISA gravitational wave mission scheduled for 2034
The Laser Interferometer Space Antenna (LISA) mission, aimed at detecting gravitational waves in space, has been approved by the European Space Agency at a meeting of its Science Programme Committee. After years of development and delays, the mission is now scheduled to go ahead in 2034.
3D printing centre investigates the potential of AM
In partnership with the Manufacturing Technology Centre (MTC), the European Space Agency (ESA) has set-up a new UK-based ‘one-stop shop’ in order to embrace the radical new technology of additive manufacturing (3D printing). The MTC, based in Coventry and home to the UK National Centre for Additive Manufacturing, will manage the new ESA Additive Manufacturing Benchmarking Centre (AMBC), which will provide a simple and easy w...
ESA's Jupiter mission will examine its turbulent atmosphere
Demanding electric, magnetic and power requirements, harsh radiation, and strict planetary protection rules are some of the critical issues that had to be tackled in order to move ESA's Jupiter Icy Moons Explorer – Juice – from the drawing board and into construction. Scheduled for launch in 2022, with arrival in the Jovian system in 2029, Juice will spend three-and-a-half years examining the giant planet's turbulent atmosphere, ...
Analytical software promises Big Bang in astrophysics
Cutting-edge software has been developed to help astrophysicists see distant galaxies as never before. With the next generation of space missions set for launch, the project will enable European scientists to take full advantage of the latest data. Astronomers are really cosmic time travellers; distant galaxies are so far away that their light takes billions of years to reach us. Discovering these stellar systems means being able to look at ...
