A year has passed since the launch of the ESA’s Rosalind Franklin rover mission was put on hold, but the work has not stopped for the ExoMars teams in Europe.

An impressive 70 mocktail recipes representing a wide range of flavours of ESA’s Jupiter Icy Moons Explorer (Juice) mission were submitted to the Agency’s #SpaceJuice competition  in January.

Europe’s Galileo is the world’s most precise satellite navigation system, providing metre-level accuracy and very precise timing to its four billion users. An essential ingredient to ensure this stays the case are the atomic clocks aboard each satellite, delivering pinpoint timekeeping that is maintained to a few billionths of a second. These clocks are called atomic because their ‘ticks’ come from ultra-rapid, ultra-stable oscillation of atoms between different energy states. Sustaining this performance demands, in turn, even more accurate clocks down on the ground to keep the satellites synchronised and ensure stability of time and positioning for users.

Passengers flying on Italy’s national carrier ITA Airways will experience fewer flight delays and greener travel thanks to pilots being able to use satellites to route their planes.

Would you like to know the future of satellite navigation? Try ESA’s Navigation Laboratory. This is a site where navigation engineers test prototypes of tomorrow's user receivers, using simulated versions of the navigation signals planned for the coming decade, such as set to be transmitted from Galileo’s Second Generation satellites. 

The interactive version of the Space Ambition book is now online, featuring all the content and images included in the hardcover edition.

Today Galileo is the world’s most precise satellite navigation system, delivering metre-level accuracy, and if you are a modern smartphone owner then you – like nearly four billion others around the world – are among its users. This week we are celebrating that almost exactly a decade ago, on 12 March 2013, Europe for the first time ever was able to determine a position on the ground using only its own independent navigation system, Galileo. 

A partnership between ESA and PLAYMOBIL continues to inspire and educate children about space. It also helps to support the children’s humanitarian organisation UNICEF and its work with vulnerable children around the world.

The NASA/ESA Hubble Space Telescope captured a series of photos of rapid changes to the asteroid Dimorphos when it was deliberately hit by a 545-kilogram spacecraft on 26 September 2022. The primary objective of the NASA mission, called DART (Double Asteroid Redirection Test), was to test our ability to alter the asteroid’s trajectory as it orbits its larger companion asteroid, Didymos. Though Dimorphos poses no threat to Earth, data from the mission could help inform researchers how to potentially change an asteroid’s path away from Earth, if ever necessary.

In 2023, ESA will be recruiting over 200 new colleagues to join our teams and support our mission of the peaceful exploration and use of space for the benefit of everyone. More than 30 vacancies have recently been published and many more will be coming soon, so if you are ready to take the next step in your career, this is your chance! Explore our vacancies and apply today.

This observation from the NASA/ESA/CSA James Webb Space Telescope features the massive galaxy cluster RX J2129. Due to Gravitational lensing, this observation contains three different images of the same supernova-hosting galaxy, which you can see in closer detail here. Gravitational lensing occurs when a massive celestial body causes a sufficient curvature of spacetime to bend the path of light travelling past or through it, almost like a vast lens. In this case, the lens is the galaxy cluster RX J2129, located around 3.2 billion light-years from Earth in the constellation Aquarius. Gravitational lensing can cause background objects to appear strangely distorted, as can be seen by the concentric arcs of light in the upper right of this image.
