Astronauts on the International Space Station do a full circle of Earth every 90 minutes and experience 16 sunsets and sunrises every day.
With this unearthly routine, astronauts can struggle to find a natural daily rhythm in space.
The Space Station follows Greenwich Mean Time (GMT), which helps keep a consistent schedule, along with regular wake-up and bedtime routines.
During his Huginn mission, our astronaut Andreas Mogensen will run two experiments focusing on sleeping in space with real world applications: Circadian Light and Sleep in Orbit.

1. Mars has two moons, Phobos and Deimos. They are both too light for gravity to make them spherical.
2. It has the highest volcano in the Solar System, the Olympus Mons. It rises 25 kilometres above the surrounding plain: Mount Everest is only one third as high.
3. The air is 100 times thinner than on Earth, and mostly made up of carbon dioxide. Human explorers will have to wear oxygen masks and special suits every time they step outside their sealed homes.
4. Like Earth, the Red Planet has two large ice caps at its north and south poles.

Did you know, the Northern lights or Aurora Borealis are created when the mythical Finnish ‘Firefox’ runs so quickly across the snow that its tail causes sparks to fly into the night sky? At least, that’s one of the stories that has been told in Finland about this beautiful phenomenon. Another that we love comes from the Sámi people of Finnish Lapland (among others), who describe them as plumes of water ejected by whales.
Today’s scientific explanation for the origin of the Aurora wasn’t thought up until the 20th Century, by the Norwegian scientist Kristian Birkeland. Charged particles, electrons and protons, are constantly emitted by the Sun, making up the solar wind. This wind slams into Earth’s ionosphere – sometimes sped up to vast speeds by solar storms – and the charged particles are deflected towards the poles by the magnetosphere.
Molecules in our atmosphere then absorb energy from these charged particles from the Sun, and re-release it in their own unique set of colours. Oxygen produces green, but at high altitudes can create red, nitrogen creates blues, and colours can overlap creating purple. Waves, twists and streams are caused by variations in Earth’s magnetic fields. This striking video shows the Aurora over Kiruna, the northernmost city in Sweden. It’s composed of images taken by the Kiruna all-sky camera every minute for about ten hours over 18-19 September 2023.
The all-sky auroral camera is operated by the Kiruna Atmospheric and Geophysical Observatory (KAGO) within the Swedish Institute of Space Physics (IRF), and data from here is provided as part of ESA’s network of space weather services within the Agency’s Space Safety Programme. A sequence of multiple coronal mass ejections – large, sudden ejections of plasma and magnetic field from the Sun – recently struck Earth, and we are still recovering from the passage of the last of them. The fastest was travelling at around 700 km/s, which is considered a small event.
Solar storms are causing an increase in geomagnetic activity; temporary disturbances in Earth’s magnetosphere, which has led to increased light shows at Earth’s poles.

Coronal Mass Ejections or CMEs, are an eruption of around a billion tonnes of particles that comes from the solar atmosphere, the corona, and travels through the solar system. CMEs are an important part of ‘space weather’. The particles spark aurorae on planets with atmospheres, and can cause malfunctions in some technology. They can also be harmful to unprotected astronauts. So it is important to understand CMEs, and be able to track their progress.

Artemis in Europe: the structure and radiators for the European Service Modules that fly NASA’s Orion spacecraft to the Moon are built in Turin, Italy.
Thales Alenia Space produces the structure that acts like a chassis on a car providing the solid foundations for all other elements to be attached to and also absorbs the forces that the Artemis spacecraft will endure during launch into Earth orbit and onto the Moon.
Technicians assemble the primary structure that is made from a core of Composite Fibre Reinforced Polymer sandwich panels and aluminium alloy elements for the secondary structures. This technology keeps the European Service Module light enough to fly farther and longer but strong enough to keep its shape.
Thales Alenia Space also supplies the radiators for the European Service Modules that consist of six elements forming two independent systems. Like a car’s radiator system the European Service Module radiators are designed to expel excess heat and keep the computers and other components inside from overheating.
The structures are trucked from Turin to Bremen, Germany, where the rest of the hardware that makes a spacecraft can be installed. The first step in their voyage to the Moon.

On 5 September 2023, teams from France’s space agency CNES and Arianegroup under the lead of ESA carried out a complete Ariane 6 launch sequence on its launch pad at Europe’s spaceport in French Guiana. The test ended with a hot-fire of the launcher’s core stage and startup of the Vulcain 2.1 engine.
This is a key step in the test campaign. It follows from initial integration of the Ariane 6 launcher on its launch pad, electrical and fluid system tests and the first launch sequence test run on 18 July 2023.
This test involved a launch sequence and final countdown representative of a launch, including removal of the Ariane 6 mobile gantry and filling the launcher’s upper and core stage tanks with liquid hydrogen and liquid oxygen. The test ended with the ignition and the startup of the core stage’s Vulcain 2.1 engine, followed by four seconds of firing.
The next milestone is to complete a core stage long hot-fire test, where the Vulcain 2.1 engine will operate for about 8 minutes.
Ariane 6 is an all-new design, created to succeed Ariane 5 as Europe’s heavy-lift launch system. With Ariane 6’s upper stage and its reignitable Vinci engine, Europe’s launch capability will be tailored to the needs of multiple payloads, for example to orbit satellite constellations. This autonomous capability to reach Earth orbit and deep space supports Europe’s navigation, Earth observation, scientific and security programmes. Ongoing development of Europe’s space transportation capabilities is made possible by the sustained dedication of thousands of talented people working in ESA’s 22 Member States.

Space exploration presents unique health challenges for astronauts due to lack of gravity, isolation, and radiation exposure. ESA’s SciSpacE activities aim to comprehend these effects and their implications for human well-being during extended missions.
ESA collaborates with researchers to conduct experiments in microgravity and analogue environments, shedding light on the consequences of space stressors. One critical concern is muscle and bone atrophy. Despite daily exercise routines, astronauts face deterioration. ESA is investigating electrical stimulation as a potential countermeasure, with tests planned on board the International Space Station.
The “Muscle Stimulation” experiment is a centrepiece of this research. By applying controlled electric currents to leg muscles, the study aims to enhance muscle mass, strength, and recovery. Complementary assessments, including MRI scans, microcirculation analysis, and blood samples, will provide a comprehensive understanding of the efficacy.
Addressing these challenges could yield benefits on Earth too. The insights gained could translate to better healthcare for diverse populations, from the elderly to clinical patients and athletes.
ESA’s dedication to advancing space exploration while safeguarding astronauts’ physical health underscores its commitment to a sustainable and thriving space programme. Through research and innovative solutions, humanity edges closer to conquering the challenges of extended spaceflight and improving life on our home planet.

Hera is complete. ESA’s asteroid mission for planetary defence was built and prepared in two halves, but now, through a painstaking operation, they have been mated together to make a single spacecraft, ready for full-scale testing of its readiness for space.
The mating took place at OHB Bremen in Germany, with Hera’s Core Module raised more than 3 m above its Propulsion Module then gradually and carefully slotted into place, over a three-hour period. The modules had been placed in cages to ensure their correct alignment relative to each other down to a few tenths of a millimetre.
Hera’s Propulsion Module incorporates its propellant tanks – housed within a central titanium cylinder, the ‘backbone’ of the spacecraft – along with piping and thrusters, which will have the job of hauling the mission across deep space for more than two years, then to manoeuvre around the Dimorphos and Didymos asteroids.
Meanwhile Hera’s Core Module can be thought of as the brains of the mission, hosting its onboard computer, mission systems and instruments.
Once the tip of the Propulsion Module cylinder met the top deck of the Core Module the mating was complete. Then an initial test bolt was inserted to check the alignment was entirely correct in advance of the two modules being fully bolted together.
The combined Hera spacecraft is scheduled to go through a test campaign to assess its readiness for spaceflight, along with the two CubeSats it will carry aboard, in preparation for its October 2024 lift-off.

This image was captured by NIRCam, Webb’s primary near-infrared camera, and contains the lensing galaxy cluster SDSS J1226+2149. It lies at a distance of around 6.3 billion light-years from Earth, in the constellation Coma Berenices. By combining Webb’s sensitivity with the magnifying effect of gravitational lensing, astronomers were able to use this gravitational lens to explore the earliest stages of star formation in distant galaxies. To do so, they relied on earlier studies by the NASA/ESA Hubble Space Telescope, which provided the ‘prescription’ for this gravitational lens.

A solar eruption detected simultaneously at Earth, the Moon and Mars emphasises the need to prepare human exploration missions for the dangers of space radiation.
During Artemis I the European Service Module (ESM) surpassed expectations. Now, as we set our sights on Artemis II, the European Service Module is ready to once again serve as Orion’s primary power and propulsion component and keep the spacecraft at the right temperature and on course. And this time, with real astronauts on board.
ESM-2 stands as a testament to ESA’s contributions to NASA’s Orion spacecraft and the Artemis programme, ensuring the crew will have the essentials – from electricity to temperature control – in the vastness of space.
Next up, ESM-2 will be connected with the crew module to create the Artemis II vehicle. It will then be thoroughly tested before launch scheduled for next year.
ESA is committed to send astronauts beyond low-Earth orbit and ultimately to the surface of the Moon and beyond. ESM is a key contribution to this joint international endeavour.
