Solar Orbiter has spotted a ‘tube’ of cooler atmospheric gases snaking its way through the Sun’s magnetic field. The observation provides an intriguing new addition to the zoo of features revealed by the ESA-led Solar Orbiter mission, especially since the snake was a precursor to a much larger eruption.

At the Thales Alenia Space test facility in Cannes, France, the massive door of the thermal vacuum chamber was opened after a month of rigorous testing of ESA’s Euclid mission to explore the dark Universe. In Cannes the fully integrated spacecraft was subjected to the conditions of space and its subsystems were fully tested for the first time. With the Euclid space telescope, scientists hope to learn more about dark matter and dark energy which could make up more than 95% of our Universe.
NASA has delivered a retroreflector array to ESA that will allow the Lunar Pathfinder mission to be pinpointed by laser ranging stations back on Earth as it orbits the Moon. Such centimetre level laser measurements will serve as an independent check on the spacecraft as it fixes its position using Galleo and GPS signals from an unprecedented 400 000 km away from Earth – proving the concept of lunar satnav while also relaying telecommunications ahead of ESA’s dedicated Moonlight initiative.
An advanced broadband satellite that can offer high-speed internet connectivity anywhere on Earth is ready to enter its final assembly ahead of launch.
The NASA/ESA/CSA James Webb Space Telescope is widely referred to as the successor to the NASA/ESA Hubble Space Telescope. In reality, it is the successor to a lot more than that. With the inclusion of the Mid-InfraRed Instrument (MIRI), Webb also became a successor to infrared space telescopes such as ESA’s Infrared Space Observatory (ISO) and NASA’s Spitzer Space Telescope.
Satellite operator Intelsat has placed an order for the first small geostationary “HummingSat” developed as part of ESA’s efforts to support fast, dynamic and agile private space firms in Europe.

Galileo has grown to become Europe’s single largest satellite constellation, and the world’s most accurate satellite navigation system, delivering metre-level positioning to more than 3.5 billion users around the globe.
It all began at ESTEC’s Test Centre, Europe’s largest satellite testing facility. This is where the very first positioning fix took place in March 2013, after the launch into orbit of the initial four IOV satellites. Following that, all 34 Galileo Full Operational Capability satellites also passed by ESTEC for their pre-flight testing.
This 3000 sq. m environmentally-controlled complex, operated and managed by European Test Services for ESA, hosts an array of test equipment able to simulate all aspects of spaceflight, from the noise and vibration of launch to the vacuum and temperature extremes of Earth orbit.
The production line at manufacturer OHB in Germany completed one new satellite every six weeks. After integration each satellite was then shipped to the ESTEC Test Centre for a three-month test campaign, after which it would be accepted by the Agency and declared ready for flight. Some facilities have had to be adapted specifically for Galileo, and the ESTEC Test Centre had to institute new security protocols because this was the first time that satellites with security restrictions were being tested at the site.
Today there are 28 of these Galileo First Generation satellites in service, with 10 more due to be launched in the next years. Upgraded Galileo Second Generation satellites are under development and will follow them into orbit later this decade.
Members of ESA’s Galileo team and ETS look back on this massive testing effort that established Galileo was ready for space.
For decades, satellites have been instrumental in monitoring our changing climate and improving our understanding of the processes that drive it. But to achieve our climate goals and make Europe the first climate-neutral continent by 2050, we need ideas that take the next step and begin to use space technologies to actively prevent, slow, reverse or otherwise address these changes.
The 2023 internship opportunities at ESA have been published! Opportunities are open for one month and positions are available in engineering, science, IT, natural/social sciences, business and administration services. This is your chance to kick-off your experience in space!
There are times when we could all do with a bit of magic in our lives. And, with the Global Climate Observing System announcement of ‘terrestrial water storage’ as a completely new Essential Climate Variable, the world of climate research and climate crisis response would certainly benefit from a satellite mission called MAGIC.
This is not an ethereal landscape of time-forgotten tombs. Nor are these soot-tinged fingers reaching out. These pillars, flush with gas and dust, ‘bury’ stars that are slowly forming over many millennia. The NASA/ESA/CSA James Webb Space Telescope has snapped this eerie, extremely dusty view of the Pillars of Creation in mid-infrared light – showing us a new view of a familiar landscape.
