ESA and NASA’s Artemis I spacecraft is cleared for launch after a series of final tests at the US Kennedy Space Center in Florida. ESA’s European Service Module (ESM) will provide electrical power and propel the uncrewed Orion capsule in an extended orbit around the Moon, setting the scene for future crewed missions. ESA has already delivered its second ESM for Artemis II and is currently building its third ESM. Eventually, Artemis III will return astronauts to the lunar surface for the first time in 50 years with the ESM supplying their life support in the form of water, food and oxygen. 

On 23 December 2021, Copernicus Sentinel-1B experienced an anomaly related to the instrument electronics power supply provided by the satellite platform, leaving it unable to deliver radar data. Since then spacecraft operators and engineers have been working tirelessly to rectify the issue. Unfortunately, despite all concerted efforts, ESA and the European Commission announce that it is the end of the mission for Sentinel-1B. Copernicus Sentinel-1A remains fully operational and plans are in force to launch Sentinel-1C as soon as possible.

The Cartwheel Galaxy, a rare ring galaxy once shrouded in dust and mystery, has been unveiled by the imaging capabilities of the NASA/ESA/CSA James Webb Space Telescope. The galaxy, which formed as a result of a collision between a large spiral galaxy and another smaller galaxy, not only retained a lot of its spiral character, but has also experienced massive changes throughout its structure. Webb’s high-precision instruments resolved individual stars and star-forming regions within the Cartwheel, and revealed the behaviour of the black hole within its galactic centre. These new details provide a renewed understanding of a galaxy in the midst of a slow transformation.

The specially trained woolly astronaut, Shaun the Sheep, has been assigned a seat on the Artemis I mission to the Moon. Shaun’s assignment was announced by ESA’s Director for Human and Robotic Exploration Dr David Parker.

Utah’s Great Salt Lake dropped to its lowest recorded water level last month as a megadrought persists across the US southwest, forcing the fast-growing city to curb its water use. From space, satellite images show how water levels have fallen from 1985 to 2022 – exposing large expanses of lakebed.

In just a few months’ time Europe’s first Meteosat Third Generation satellite will soar into the skies on an Ariane 5 rocket from French Guiana. From geostationary orbit, this new satellite, carrying two new highly sensitive instruments, will take weather forecasting to the next level. Taking a significant step towards launch, the satellite operations teams at two different centres have completed an all-important suite of tests ensuring that their procedures are fully compatible with the satellite.

ESA’s EnVision mission to Venus will perform optical, spectral and radar mapping of Earth’s sister planet. But before getting down to work the van-sized spacecraft needs to ‘aerobrake’ – lowering its orbit with thousands of passages through the planet’s hot, thick atmosphere for up to two years. A unique ESA facility is currently testing candidate spacecraft materials to check they can safely withstand this challenging process of atmospheric surfing.

Any movement beneath our feet – from barely perceptible subsidence to the sudden appearance of a sinkhole or a crashing landslide – spells big trouble. Even relatively modest subsidence can weaken buildings and infrastructure and lead to issues such as flooding, and at worst the abrupt disappearance of sections of land brings immediate threat to life. Monitoring and predicting our shifting land is clearly essential for adopting mitigating strategies.

ESA’s efforts to ensure European citizens reap the benefits of space have been highlighted at a global aerospace event held in the UK.

A large data-driven telecommunications satellite that uses innovative technology to keep cool as well as other innovations – developed under an ESA Partnership Project – has started its commercial service.

ESA’s upcoming EarthCARE satellite mission has just taken a big stretch. Engineers have gently unfolded this new satellite’s huge five-panel solar wing to test that it will deploy correctly once it is in space. The solar wing is a critical part of the satellite, providing the energy for EarthCARE to do its job: to quantify the role that clouds and aerosols play in heating and cooling Earth’s atmosphere.

With searing temperatures and a string of record highs being smashed across western Europe, the current heatwave is all too apparent. Extreme heat warnings have been issued in several countries including France, Spain and Portugal, and deadly wildfires have forced thousands to flee their homes. The satellite images here are an example of how the crisis is being viewed by satellites orbiting Earth.

On 21 July 2022, ESA astronaut Samantha Cristoforetti will head outside the International Space Station on a spacewalk alongside cosmonaut Oleg Artemyev. It will be Samantha’s first spacewalk, and the first conducted by a European woman.
