Modern society is growing ever-more reliant on services and data delivered via space. Cyber threats and disruptions to satellites are increasingly dangerous to citizens and economies, and it is vital to protect them and the crucial work they do. This is why ESA is supporting Swiss-based security firm Cysec in organising Europe’s first live cybersecurity demonstration for space systems. The demonstration will highlight the challenges in making space systems cybersecurity resilient vs modern hacking techniques and capabilities. View the full article

Video: 00:06:30 As always, a new year brings new and exciting missions and launches for ESA. In science the world looks forward to the first image releases of the recently launched James Webb Space Telescope and the third data release for Gaia, both teaching us more about our galaxy and Universe. ESA’s new Mars rover will be launched with the ExoMars mission, and we will also see the maiden flight of Vega-C and the Artemis I flight. Astronaut Samantha Cristoforetti will return to the ISS for her second mission and a new class of astronauts will be presented to the world. After the groundwork has been laid in 2021, a new Ministerial Council Meeting will gather to l…

A contract signed with Arianespace secures the joint launch for two satellites that will further knowledge of our home planet. Scheduled to lift off on a new class of rocket, ESA’s Vega-C, from Europe’s Spaceport in mid-2025, FLEX will yield new information about the health of the world’s plants and Altius will deliver profiles of ozone and other trace gases in the upper atmosphere to support services such as weather forecasting.

ESA’s exoplanet mission Cheops has revealed that an exoplanet orbiting its host star within a day has a deformed shape more like that of a rugby ball than a sphere. This is the first time that the deformation of an exoplanet has been detected, offering new insights into the internal structure of these star-hugging planets. View the full article

Video: 00:02:16 Join ESA astronaut Matthias Maurer inside Kibo, the Japanese laboratory module of the International Space Station in 360°, setting up Astrobee robotic free-flyers for the ReSWARM experiment, short for RElative Satellite sWArming and Robotic Maneuvering. The robotics demonstration tests autonomous microgravity motion planning and control for on-orbit assembly and coordinated motion. Thus, this investigation aims to test coordination between multiple robots, robots and cargo, and robots and their operating environment as developers envision the future of autonomous robot operations in space. Matthias was launched to the International Space Station on…

Video: 00:02:15 Tour the new launch complex for Ariane 6 at Europe's Spaceport in French Guiana. First, enter the launch vehicle assembly building which is 20 m tall, 112 m long, and 41 m wide, located a kilometre away from the launch zone. It is used for horizontal integration and preparation of the central core of Ariane 6 – its main stage and upper stage – before it is rolled out to the launch zone. The hydrogen and oxygen storage facilities connect to the launch pad via underground pipes as part of the launch support systems. The 8200 tonne 90 metre-high mobile gantry rolls on rails. Its platforms enable engineers to access the vehicle for integration of the b…

Video: 00:01:27 Experience an orbital badminton match on the International Space Station ISS in 360° as ESA astronaut Matthias Maurer challenges his crewmates and Japanese spaceflight participants Yusaku Maezawa and Yozo Hirano. Together with Roscosmos cosmonaut Alexander Misurkin, the Japanese spaceflight participants joined the current Expedition 66 crew for a short-term stay of 12 days on the ISS. While their stay on the ISS focuses on scientific and operational activities, the astronauts on board the Space Station also enjoy recreational activities that provide an important balance for the crew and offer opportunities for intercultural exchange and team buil…

Video: 00:03:04 This real-time video shows the separation of the James Webb Space Telescope from the Ariane 5 launch vehicle and the subsequent solar array deployment. Webb’s launch on an ESA-provided Ariane 5 rocket was performed by Arianespace on behalf of ESA from Europe’s Spaceport in French Guiana, at 12:20:07 GMT (13:20:07 CET) on 25 December 2021. Webb separation from the Ariane 5 occurred at 12:47:14 GMT (13:47:14 CET) with solar array deployment starting 69 seconds later. Thanks to Ariane 5’s highly precise launch trajectory Webb’s solar array was able to deploy soon after separation from the Ariane 5, capturing sunlight to power the observatory. This vid…

After a successful launch of the NASA/ESA/CSA James Webb Space Telescope on 25 December, and completion of two mid-course correction manoeuvres, the Webb team has analysed its initial trajectory and determined the observatory should have enough propellant to allow support of science operations in orbit for significantly more than a 10-year lifetime (the minimum baseline for the mission is five years).

Video: 00:01:22 On Thursday 23 December, the James Webb Space Telescope, safely stowed inside the fairing of ESA’s Ariane 5 launch vehicle, left the final assembly building for roll-out to the launch pad at Europe’s Spaceport in French Guiana. Webb, no longer in sight since its encapsulation in the fairing on 17 December, has been closely monitored. The fairing is equipped with specialised environmental controls that keep the observatory in a perfectly controlled temperature and humidity range during its final few days on Earth. Ariane 5, standing 53 m high on its mobile launch platform was transported along rails from the final preparation building to the launch …

Image: The James Webb Space Telescope is safely stowed inside the fairing of ESA’s Ariane 5 launch vehicle, which is now on the launch pad undergoing final checks and fuelling for a targeted liftoff at 12:20 GMT / 13:20 CET on 25 December from Europe's Spaceport in French Guiana. Webb will be the largest, most powerful telescope ever launched into space. As part of an international collaboration agreement, ESA is providing the telescope’s launch service using the Ariane 5 launch vehicle. Working with partners, ESA was responsible for the development and qualification of Ariane 5 adaptations for the Webb mission and for the procurement of the launch service by Arianespa…
