New dawn, new possibilities... 16 times a day!

This picture was published on social media by ESA astronaut Sophie Adenot with the following caption:

Day 080, orbit 1241 — New dawn, new possibilities… 16 times a day! From orbit, just like on Earth, each sunrise and sunset is a quiet reminder of how dynamic and beautiful our planet is. At sunrise, the deep black of night gives way to fiery reds, warm oranges and the thin blue line of our atmosphere. 

No two sunrises are ever the same, depending on the clouds, their shapes, and whether we’re flying over ocean or land… I can’t help but think of the way Monet or Van Gogh studied light… how much they would have loved this view!

--

Jour 080, orbite 1241 — Nouvelle aube, nouvelles perspectives… 16 fois par jour ! Depuis l’orbite, comme c’est aussi le cas sur Terre, chaque lever et coucher de Soleil rappelle combien notre planète est belle et dynamique. À l’aube, le noir profond de la nuit laisse place à des rouges flamboyants, des oranges chaleureux, et à la fine ligne bleue de notre atmosphère.

Aucun lever de Soleil ne se ressemble vraiment : tout dépend de la couverture nuageuse, de la forme des nuages, et du fait que l’on survole les océans ou les continents… Impossible de ne pas penser à la manière dont Monet ou Van Gogh ont étudié la lumière… qu’ils auraient adoré cette vue !

ESA XR Conference 2026

Every two years, the ESA XR Conference brings together professionals and experts working with Extended Reality (XR) and related technologies in the space sector.

The 2026 edition took place on 17-18 March at ESA’s European Astronaut Centre (EAC) in Cologne, Germany.

For over two decades, the European Space Agency (ESA) has explored the potential of Extended Reality (XR) – a group of technologies encompassing Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) – to enhance its operations.

These immersive technologies bridge the digital and physical worlds, enabling more intuitive workflows, improving collaboration, reducing costs, and supporting mission planning, training, and data interpretation.

This Month at ESA: April 2026

What did space deliver for Europe this month? From the Moon to low Earth orbit and beyond, here’s what the European Space Agency has been up to.

The great parachute bake-out

The great parachute bake-out

Baking a parachute for Mars

Watch ESA’s Mars chief engineer Albert Haldemann explain the sterilisation process of one of the parachutes of the ExoMars Rosalind Franklin rover mission and why it matters.  

Carefully wrapped inside a donut-shaped bag is a 35-m diameter parachute, about to be baked inside a specialised dry-heat steriliser oven. The parachute needs to be at least 10 000 times cleaner than your smartphone. 

To get rid of any microbes it might have picked up during its time on Earth, the parachute was heated up in a specialised oven at the European Space Agency’s Life Support and Physical Sciences Laboratory at ESTEC, the agency’s technical centre in the Netherlands. All air inside the cleanroom continuously passes through a two-stage filter, and everyone entering the chamber must gown up more rigorously than a surgeon before passing through an air shower to remove any contaminants. 

The 74 kg parachute, made mostly of nylon and Kevlar fabrics, will endure a six-minute dive into the thin martian atmosphere and slow down the ExoMars Rosalind Franklin rover for a safe landing on the Red Planet. This feat will make it the largest parachute ever to fly on the Red Planet, or anywhere else in the Solar System besides Earth.  

The ExoMars Rosalind Franklin rover mission will launch in 2028 and spend over 25 months travelling to the Red Planet where it will search for signs of life beneath the martian surface. 

The potential existence of past and perhaps even present-day life on our closest planetary neighbour requires rigorous sterilisation, to make sure that no microbes piggyback their way there from Earth. Any terrestrial microbes hardy enough to survive the ride through space could interfere with the investigation by causing ‘forward contamination’ and triggering a false positive. 

Protecting the martian environment from ourselves, in accordance with international planetary protection measures, is as important as protecting the mission itself. 

Ariane 6 VA268 launch campaign

Set for 30 April, Ariane 6 is preparing for launch from Europe’s Spaceport in French Guiana. Mission VA268 will place 32 Amazon LEO satellites into low Earth orbit, supporting the deployment of Amazon’s global broadband constellation. This will be the second Ariane 6 flight in its four‑booster Ariane 64 configuration.

Aurora, Swing and Sawa: ESA’s Space Weather sensors

Solar activity regularly disturbs our planet, producing stunning auroras, but also endangering infrastructure in space and on the ground.

Meet the space weather sensors, Aurora, Swing and Sawa, ESA’s missions to monitor Earth’s atmosphere and study geomagnetic storms.

Think of Earth’s atmosphere as a layered cake: each layer is affected by space weather in its own way, and each mission will focus on different effects.

The Aurora mission will patrol the north and south poles, looking down on the shimmering lights that reveal the impact of space weather.

Swing will monitor the ionosphere, a layer of the atmosphere that, when disturbed, can disrupt radio signals and cause issues with satellite navigation and communication systems.

Sawa will study the thermosphere as space weather causes it to warm and expand, pushing satellites off course.

Aurora, Swing and Sawa, along with sensors onboard other satellites and on Earth’s surface, will feed data into space weather forecasts, alerts and other tools. Together, these services will help protect industries such as aviation, satellite navigation and power grids from disruption.

We cannot prevent space weather, but with the space weather sensors developed by ESA’s Space Safety programme, Europe will know when to brace for impact.

Aeolus comes home to forge a lasting lidar legacy

The islands of Aeolia, the home of Aeolus, keeper of the winds in Greek mythology, were a fitting location to explore the legacy of the European Space Agency’s trailblazing wind satellite, and the future of spaceborne Doppler wind lidars.

Aeolus was a remarkable achievement. Its ALADIN instrument used innovative laser technology and the Doppler effect to measure vertical profiles of Earth’s winds on a global scale for the very first time from space.

At the Aeolus science conference in Lipari, April 2026, we discovered the history of this pioneering feat - and how the hard work developing Aeolus has helped the development of current instruments such as EarthCARE’s atmospheric lidar (ATLID) and paved the way for the future operational EPS Aeolus/Aeolus-2 mission – a joint endeavour between ESA and EUMETSAT.

Flight and satellite tracks in Arctic campaign

As sea ice continues to succumb to the climate crisis, measuring its decline with precision has never been more urgent. To meet this challenge, the European Space Agency is developing three new Copernicus satellites, each employing distinct but complementary techniques to monitor this fragile component of the Earth system. To ensure the data from these new satellites are razor-sharp, an international team of hardy scientists is now out on the Arctic sea ice braving the cold and flying above to collect critical in situ measurements.

Through coordinated measurements on the ice and from the air, the teams are collecting critical data to improve the upcoming CIMR, CRISTAL and ROSE-L mission’s retrieval methods and help ensure these important upcoming satellites deliver accurate and reliable observations of the polar environment.

The video shows two flight tracks and several satellite tracks during the field campaign.

Inchworm-inspired soft robot

Researchers at the University of Gothenburg developed an inchworm-inspired soft robot as part of an ESA Discovery activity exploring new approaches to soft robot locomotion for planetary exploration. The robot uses a rolled dielectric elastomer actuator – a type of artificial muscle – to mimic the inchworm's contracting and extending motion, and is designed to be lightweight, power-efficient and resilient enough to operate in the harsh conditions of space.

A Saturday‑night dinner onboard the International Space Station

After an intense few weeks the crew took time to celebrate together with a shared meal proposed by ESA astronaut Sophie Adenot.

It’s a long‑standing tradition: each ESA astronaut works with a chef to create a few special dishes reserved for rare occasions — known as “bonus food”. Sophie’s bonus food was created by multi‑Michelin‑starred chef Anne‑Sophie Pic, offering the crew a taste of French gastronomy far from Earth.

Bonus food, tailored to specific crew members, makes up around one tenth of an astronaut’s menu. Astronauts say it adds variety to their meals, supports mental well‑being, and helps strengthen bonds among the crew in orbit.

Everyday operations in orbit: toilet maintenance

In this timelapse, ESA astronaut Sophie Adenot performs routine maintenance on the Waste and Hygiene Compartment, or WHC – the ISS toilet system. She is replacing the full solid-waste container in which solid waste is vacuum-dried, compressed and kept airtight. This operation typically takes place once or twice a week, when the container reaches capacity.

Plato enters special space-like chamber

This timelapse video captures the activities to move Plato into the Large Space Simulator (LSS) at ESA’s Test Centre. Inside the LSS, Europe's largest cryo-vacuum chamber, Plato had to demonstrate that it can withstand the extreme temperatures and vacuum of space.

In the video we see how engineers used a special crane to lift Plato out of a cleanroom through an opening in the ceiling and move it over the top opening of the LSS. Then, the spacecraft was gently lowered into the dark-walled chamber, all the way down to a supporting frame that holds the spacecraft in place.

Once the chamber’s top and side hatches were sealed, engineers began a series of vital tests of the spacecraft under space‑like conditions.

Many of the tests were designed to verify that Plato’s 26 cameras performed as required for achieving the mission’s main goal: to discover potentially habitable, Earth-like planets around Sun-like stars.

In the video, Plato’s delicate cameras are covered with a blanket to protect them from stray dust particles.
