Methane is the second most important greenhouse gas contributor to climate change after carbon dioxide. Curbing methane emissions could deliver immediate and long-lasting benefits for the climate, seeing as the gas only lingers in the atmosphere for a relatively short time. Satellites have a really important role to play in reducing greenhouse gas emissions. The Tropomi instrument onboard the Copernicus Sentinel-5P satellite is the only instrument that maps global methane concentrations every single day. This lets scientists detect hotspots for large methane sources around the world – allowing us to address the consequences of methane emissions on our climate and environment.

There is no point in sending human explorers on long voyages around the solar system if they arrive at their destination in poor physical shape. Long stays in zero gravity are not good for the human body.
We already know that astronauts lose bone mass at around 1% for every month they are in space; muscles – including heart muscles – atrophy despite hours of exercise; and there are a host of other problems.
Never before has a telescope been able to create such razor-sharp astronomical images across such a large patch of the sky.
On Tuesday 7 November, ESA will release the first full-colour images captured by its recently launched Euclid space telescope. These images form part of the mission’s ‘Early Release Observations’ – where Euclid was tasked with scrutinising a set of celestial targets chosen for their public appeal and scientific value.
The five images are full of cosmic secrets waiting to be revealed. And this is just the beginning. During its six-year mission, Euclid will generate the equivalent of a million DVDs of data. These data will be used to create the biggest ever 3D map of the Universe and uncover the secrets of dark matter and dark energy.
In this video, hear from the experts about how Euclid has reached this milestone. Discover how they felt when they saw the first images, and find out what these images will reveal about the cosmos.
Watch the reveal of the images live through ESA Web TV or YouTube on 7 November, 13:15 GMT / 14:15 CET. At the same time, an ESA press release including all images will be published at esa.int/euclid.

ESA’s Euclid mission is on a quest to unveil the nature of two elusive ‘dark’ entities. As the renowned theoretical physicist Stephen Hawking remarked in 2013, “The missing link in cosmology is the nature of dark matter and dark energy”.
During the last 70 years, scientists have made enormous progress in understanding the very initial phases of the Universe and its evolution to the present day. Thanks to advances in observations and theoretical modelling, a clear picture has emerged of how stars form, and how galaxies grow and interact with each other, coming together to form groups and clusters.
Yet, fundamental mysteries remain. 95% of the Universe appears to be made up of unknown ‘dark’ matter and energy. Dark matter and energy affect the motion and distribution of visible sources but do not emit, reflect or absorb any light. And scientists do not know what these dark entities actually are.
To address this question, Euclid will create a great map of the large-scale structure of the Universe across space and time by observing with unprecedented accuracy billions of galaxies out to 10 billion light-years. This is not easy, and making sure that Euclid is up to the task has required the expertise and dedication of many people over several years of work.
This video captures the journey behind the Euclid mission, from a human and intensely visual perspective. It shows tiny screws, winding cables and shiny surfaces in a whole new light, revealing how each piece comes together to form the space telescope. Be drawn in by awe-inspiring photos of the cosmos, and stay for the seemingly choreographed ballet of teamwork necessary to assemble and test the spacecraft, before being swept away by the emotion of the launch into space.
Euclid’s adventure has begun. With its observations during the coming years, it will help us uncover the missing link in cosmology and open the gate to the ‘dark’ side of the Universe.

The giant planet shines bright in the night sky this week as it reaches opposition on Thursday (2 November.)
This means it is at its biggest when seen from Earth, and spends much of the night above the horizon – so it’s the perfect time to observe Jupiter yourself!
If you don’t have a telescope handy, don’t worry. You will be able to spot the planet with just your eyes. Look for a bright orange star-like dot just above the eastern horizon that is not twinkling. This is our big friendly giant! You can also use a stargazing app to help you find the planet.
Through a pair of binoculars, Jupiter will look like a white disk. Peer closely and you will see a line of three or four tiny white dots. These dots are Jupiter’s largest moons: Ganymede, Callisto, Io and Europa. These will soon be visited by our Jupiter Icy Moons Explorer, or Juice for short.
Use a telescope if you’re curious to see Jupiter’s famous red spot and brown bands.
Try to find a clear sky this week and say… hello Jupiter!
Humans are adaptable beings. Wear glasses that turn your view of the world upside-down and within two weeks your brain will have adapted to the topsy-turvy world.
Researchers suspect that astronauts’ brains adapt to living in weightlessness by using previously untapped links between neurons. As the astronauts learn to float around in their spacecraft, left–right and up–down become second nature as these neuronal connections are activated.
To confirm this theory, up to 16 astronauts will be put through advanced Magnetic Resonance Imaging (MRI) scanners before and after their flights to study any changes in their brain structure. A control group on ground will undergo the same scans for further comparison.
The research is providing scientists on Earth clues where to look in the brains of people who suffer from disorders based on previous traumatic experiences such as vertigo.

When astronauts return to the lunar surface they are probably going to be doing more driving than walking – but to keep billowing moondust at bay they are going to need roads. An ESA project reported in today’s Nature Scientific Reports tested the creation of roadworthy surfaces by melting simulated moondust with a powerful laser.

The 29th SpaceX commercial resupply services (CRS) mission for NASA carries scientific experiments and technology demonstrations, including studies of enhanced optical communications and measurement of atmospheric waves. The uncrewed SpaceX Dragon spacecraft is scheduled to launch to the International Space Station from the agency’s Kennedy Space Center in Florida no earlier than Nov. 5.
Like every other living creature we know of, humans evolved at the bottom of a gravity well. We take the Earth’s tug for granted, and so do our bodies. So it’s not surprising that our bodies behave oddly in orbit. What is surprising is that humans turn out to adapt remarkably well to zero-g (more precisely, microgravity).
At some point, statistically speaking, a large asteroid will impact Earth. Whether that’s tomorrow, in ten years, or a problem for our descendants, ESA is getting prepared.
As part of the world’s first test of asteroid deflection, ESA’s Hera mission will perform a detailed post-impact survey of Dimorphos – the 160-metre asteroid struck, and successfully deflected, by NASA’s DART spacecraft.
Hera will soon study the aftermath. Launching in October 2024, Hera will turn this grand-scale experiment into a well-understood and hopefully repeatable planetary defence technique.
But before Hera and its two CubeSats fly, they’re rigorously tested at ESA’s ESTEC test centre in Noordwijk, the Netherlands. From the force and noise of the rocket take-off to the sustained vacuum and temperature extremes of deep space, all aspects of Hera’s functioning are checked before they begin their journey, alone in space.

2409 new objects were launched into space in 2022, that’s more than ever before.
Last year though, also saw a record number of satellites reenter Earth’s atmosphere.
The rising number of reentries is not necessarily a bad thing. Disposing of satellites efficiently is one of the most important things for keeping low-Earth orbits safe.
However, most objects reenter in an uncontrolled manner: they are switched off at the end of their mission and left to fall and burn up in Earth’s atmosphere.
There is good news though. Advancing technology has seen a recent increase in “controlled reentries” for rocket bodies. A controlled reentry allows operators to remove their hardware from protected regions more quickly and with greater control over where, when and how it reenters – and even lands – at the cost of allocating some fuel to do so.
By the way, just because an older satellite wasn’t designed to be controlled during its descent doesn’t mean it’s impossible to do so. In July 2023, our teams guided the Aeolus satellite to burn up over uninhabited regions in the Atlantic and Antarctica, even though the satellite was designed in the late 1990s with no intention to control it in this way.

Nestled between the colossal martian ‘Grand Canyon’ (Valles Marineris) and the tallest volcanoes in the Solar System (the Tharsis region) lies Noctis Labyrinthus – a vast system of deep and steep valleys that stretches out for around 1190 km (roughly the length of Italy here on Earth).
This video visualises a flight over the eastern part of Noctis Labyrinthus as seen by Mars Express’s High Resolution Stereo Camera (HRSC). It presents a perspective view down and across this fascinating landscape, showing distinctive ‘graben’ – parts of the crust that have subsided in relation to their surroundings. The intense volcanism in the nearby Tharsis region is to blame for the formation of these features; this volcanism caused large areas of martian crust to arch upwards and become stretched and tectonically stressed, leading to it thinning out, faulting and subsiding.
The highest plateaus seen here represent the original surface level before chunks of surface fell away. The intersecting canyons and valleys are up to 30 km wide and six km deep. In many places, gigantic landslides can be seen covering the valley slopes and floors, while other valley slopes show large dune fields created by sands blown both down and upslope by martian winds.
ESA has highlighted Mars Express images of Noctis Labyrinthus before, in 2006 and 2015. Mars Express has orbited the Red Planet since 2003, imaging Mars’s surface, mapping its minerals, studying its tenuous atmosphere, probing beneath its crust, and exploring how various phenomena interact in the martian environment. For more from the mission and HRSC, see ESA’s Mars Express releases.
Processing notes: The video was created using an image mosaic built over eight orbits (0442, 1085, 1944, 1977, 1988, 10497, 14632 and 16684) by ESA’s Mars Express and its HRSC. This mosaic is combined with topographic information from a digital terrain model to generate a three-dimensional landscape, with every second of the video comprising 50 separate frames rendered according to a pre-defined camera path. The opening credits (Mars globe, first 24 seconds) were created using the recent 20-year Mars global colour mosaic; this opening sequence has a three-fold vertical exaggeration, while the subsequent flight animation has a 1.5-fold exaggeration. Haze has been added to conceal the limits of the terrain model, and starts building up at distance of between 150 and 200 km. The video is centred at the martian coordinates of 7°S, 265°E.
Alt-text: The video begins on a rotating full-globe of Mars, with white polar caps and mottled tan surface visible. It then zooms in on the westernmost part of the large Valles Marineris canyon system, a region highlighted by a white box, and swaps to a new Mars Express visualisation of Noctis Labyrinthus. The camera then flies slowly across a landscape that is broken apart by deep intersecting valleys and canyons.
