On Wednesday 19 August, media representatives were invited to a media briefing ahead of the launch of the next Meteosat Third Generation Imager satellite (MTG-I2). The satellite is set to be launched on an Ariane 6 from Europe’s Spaceport in French Guiana, on 27 August. 

MTG-I2 is the third satellite for MTG, completing the MTG constellation. Together the satellites will produce images for weather forecasting in Europe in unprecedented detail. This mission provides new data products and capabilities for European weather services, especially suited to nowcasting of severe weather events.

The MTG-Imager satellites carry two instruments, a Lightning Imager and a Flexible Combined Imager. The Lightning Imager offers completely new capabilities for European meteorological satellites by continuously monitoring for lightning. The Flexible Combined Imager builds a picture of fast-evolving weather systems and can be used to issue timely weather warnings. It is able to scan the entire surface of Earth as viewed from its geostationary position (36 000 km above the equator) in just 10 minutes and can scan Europe and northern Africa every 2.5 minutes.

ESA’s Mars Express takes us on another mesmerising flight, this time around one of the biggest craters on Mars. 

Despite measuring a huge 460 km across, Schiaparelli Crater seems to be relatively shallow. Perhaps it has been filled in over the last few billion years by sediment blown by the wind or deposited by water, by lava – or by a combination of all three. 

Schiaparelli Crater is named after Italian astronomer Giovanni Schiaparelli (1835–1910). Although he studied Mercury and Venus, he is best known for his observations of the Red Planet. 

During the ‘Great Opposition’ of 1877, when Mars passed close to Earth, Schiaparelli mapped the planet, perceiving several straight dark lines across the red surface. He assumed that these were natural water-filled channels and used the equivalent Italian word, ‘canali’. 

However, other astronomers thought he meant canals, meaning artificial irrigation and transportation routes, which led to a few astronomers, and a large number of the general public, believing that they had been created by intelligent martians. 

Now we know that Schiaparelli’s ‘canali’ were illusions created by the comparatively poor telescopes of the time and there are no water-filled channels on Mars today. Nevertheless, we do believe that water was once present in this region of the planet, perhaps in the form of a lake. 

Schiaparelli Crater is also important in popular culture, being the final destination of astronaut Mark Watney in Andy Weir’s novel ‘The Martian’. 

Enjoy the flight, and be sure to turn up the volume for the full audio guide experience. 

Processing notes: 

This film was created using the Mars Express High Resolution Stereo Camera Mars Chart (HMC-30) data, image mosaics made from multiple observations by the mission’s High Resolution Stereo Camera (HRSC). The mosaic image, centred at 8°S/17°E, is combined with topography information from the digital terrain model to generate a three-dimensional landscape. 

For every second of the movie, 50 separate frames are rendered following a predefined camera path in the scene. The vertical exaggeration used for the animation is three-fold. Atmospheric effects, like clouds and haze, have been added to conceal the limits of the terrain model. The haze starts building up at a distance of 250 km. 

The HRSC camera on Mars Express is operated by the German Aerospace Center (DLR). The systematic processing of the camera data took place at the DLR Institute for Space Research in Berlin-Adlershof. The working group of Planetary Science and Remote Sensing at Freie Universität Berlin used the data to create the film. 

About 12 billion years ago, a dwarf galaxy known as LKH (left) collided with a young Milky Way (right) and merged with it. This artist’s concept portrays that collision. The NASA/ESA Hubble Space Telescope uncovered definitive evidence of this long-ago collision by studying ancient globular star clusters.

[Image description: An illustration of two galaxies in the midst of a collision against a dark, star-filled background. The collision takes up the middle third of the illustration. On the right, a larger galaxy is viewed at an angle from 11 o’clock to 4 o’clock, with a white-yellow core surrounded by mottled brown dust lanes and faint bluish spiral arms. To the left, a smaller, bright blue-white galaxy is stretched into a curved, hook-like shape as gravity distorts it. A broad, glowing bridge of pale blue gas and stars extends off the galaxy at the left, while wispy streams extend above and below the larger galaxy at the right. The words “Artist’s Concept” appear in the lower left corner.]

This is a ‘musification’ – an artistic interpretation of a set of data. In this case, the eclipse determines when and how much of each sound is heard. The music is simply the way those data are presented.

This musification is a collaboration ESA’s CESAR team and Rubén García Benito from the Instituto de Astrofísica de Andalucía (IAA-CSIC). It uses nine parameters extracted from a Stellarium simulation of the total solar eclipse:

Arpeggio (the rapid succession of notes): Visible sunlight. Its rhythm, range (spanning almost four octaves), and volume are determined by the light itself; the chord follows the colour of the sky. It fades out as the Sun sets. (The data determine the behaviour; the scale and pattern are artistic choices.)

Pad (background chord): The colour of the light; the redder and warmer the light becomes, the darker the chord. (The colour is the data.)

Bass (sub): The weight of the darkness; deepest during totality. (Data-driven.)

Heartbeat: The tension, reflecting how quickly the light is falling; it comes to rest during totality. (Data: rate of change.)

Bells: The actual contacts C1, C2, maximum eclipse and C3 (there is no C4, as the Sun sets before the eclipse ends). (Sonification: marking a real moment in time.)

Shimmering sound during totality: The solar corona. (A musical element placed at the real event.)

Descending whoosh: The exact moment when the Sun disappears behind the horizon. (An icon of the event; not measured wind.)

Low night drone: The onset of night (entering when the Sun passes below the horizon). (Data: when it happens and to what extent.)

Stars (soft sparkling tones): The stars that become visible at night (but not during totality). (Data: when they appear and how many are visible.)

Se trata de una musificación, es decir, una interpretación artística de un conjunto de datos. En este caso, el eclipse determina cuándo se escucha cada sonido y con qué intensidad. La música es simplemente la forma en que se presentan esos datos.

Esta musificación es fruto de una colaboración entre el equipo CESAR de la ESA y Rubén García Benito, del Instituto de Astrofísica de Andalucía (IAA-CSIC). Utiliza nueve parámetros extraídos de una simulación del eclipse solar total realizada con Stellarium:

• Arpegio (rápida sucesión de notas): La luz solar visible. Su ritmo, extensión (que abarca casi cuatro octavas) y volumen están determinados por la propia luz; el acorde sigue el color del cielo. Se desvanece a medida que el Sol se pone. (Los datos determinan el comportamiento; la escala y el patrón son elecciones artísticas).
• Pad (acorde de fondo): El color de la luz. Cuanto más rojiza y cálida se vuelve la luz, más oscuro es el acorde. (El color es el dato).
• Grave (subgrave): El peso de la oscuridad, que alcanza su máxima intensidad durante la totalidad. (Basado en datos).
• Latido: La tensión, que refleja la rapidez con la que disminuye la luz; se calma durante la totalidad. (Dato: tasa de cambio).
• Campanas: Los contactos reales C1, C2, máximo eclipse y C3 (no hay C4 porque el Sol se pone antes de que termine el eclipse). (Sonificación: marca un instante real en el tiempo).
• Brillo suspendido durante la totalidad: La corona solar. (Elemento musical situado en el momento real del acontecimiento).
• Soplo descendente: El instante exacto en que el Sol desaparece tras el horizonte. (Un recurso sonoro que representa el evento; no se trata de viento medido).
• Zumbido (dron) nocturno grave: El inicio de la noche (cuando el Sol desciende por debajo del horizonte). (Datos: cuándo ocurre y en qué grado).
• Estrellas (suaves tonos centelleantes): Las estrellas que se hacen visibles durante la noche (pero no durante la totalidad). (Datos: cuándo aparecen y cuántas son visibles).

When the Moon passes between Earth and the Sun, it casts a shadow onto Earth's surface. For people in the darkest part of this shadow, the face of the Sun is totally blocked out, and its wispy atmosphere becomes visible.

On Wednesday 12 August, such a shadow will cross Greenland, Iceland, northeastern Portugal and Spain. With this being the first total eclipse visible from mainland Spain since 1905, the European Space Agency (ESA) has decided to do something special.

ESA’s live broadcast from the Observatorio Astrofísico de Javalambre will allow anyone to experience this rare phenomenon from anywhere in the world. Meanwhile, the Agency is working with the City and University of León to organise a free in-person event, inviting people to come together for a day of interactive workshops, talks and live observations.

This NASA/ESA/CSA James Webb Space Telescope Picture of the Month takes us to a fantastical realm within our home galaxy, where piercing starlight and billowing winds sculpt dust clouds into inventive shapes. This scene is from the Carina Nebula, which lies just 7500 light-years away in the constellation Carina (the Keel).

Spanning roughly 260 light-years, the nebula is home to an incredible collection of objects, including the Cosmic Cliffs revealed in the first-ever Webb image release. The Carina Nebula is also the nearest high-mass star-forming region that allows astronomers to study the full range of star formation. This nebula houses some of the most massive stars in our galaxy as well as tens of thousands of protostars, offering a valuable opportunity to understand how stars shape their neighbourhoods.

The feature highlighted in today’s image, aptly called the Treasure Chest, looks right at home in this celestial sculpture garden. The Treasure Chest is what’s known as a cometary globule. A cometary globule is an isolated cloud of gas and dust with a dense, dark head and a sweeping tail. These clouds often somewhat resemble comets, but the Treasure Chest looks distinctly like a wooden chest with its lid wide open.

However, this chest doesn’t contain jewels or gold coins, but instead a compact cluster of young stars. These stars are responsible for the otherworldly glow coming from within the Treasure Chest, revealed by Webb’s sensitive Near-Infrared Camera (NIRCam). Researchers estimate that the Treasure Chest’s cluster contains about 70 stars, the most massive of which is a rare O-type star roughly 19 times as massive as the Sun.

The star cluster is likely around 1.3 million years old, though earlier estimates found it to be as young as just 100 000 years old. Because of its youth, the cluster is still deeply embedded within the dusty clouds of the Treasure Chest. The individual stars in the cluster are wrapped up in dust as well; astronomers have found evidence that many of these stars are surrounded by circumstellar discs. Over time, the brilliant starlight from these young stars will dissipate the surrounding cloud and reveal the entire cluster.

The key to the Treasure Chest’s sculptural shape lies outside this image: just 39 light-years to the northwest, as measured on the sky, sits Eta Carinae, the most luminous object in the entire Carina Nebula. Eta Carinae is a star system containing at least two stars, one of which is 100 times as massive as the Sun. This star alone is about 5 million times as luminous as the Sun. Adding to this intense radiation is the nearby star cluster Trumpler 16, which also contains several extremely hot massive stars.

With Webb, astronomers have carried out an observing programme (#5408; PI: Reiter) dedicated to studying how young stars in the Carina Nebula collect gas from their surroundings and expel it through outflows.

[Image Description: A region of space filled with bright stars and clouds of gas. In the centre, the densest clouds form the shape of a chest with its lid open. The chest appears to glow from within. At its base it breaks apart into long pillars of thick gas. Many of the gas clouds in the background are dark orange globules, while others form large, pale hazes. A few brightly shining stars lie in the foreground, the biggest and brightest in front of the chest’s lid.]

[English] Day 167 orbit 2587 — Movies sometimes make it look easy to put on a spacesuit and head outside the spaceship. In reality, getting two astronauts and their spacesuits ready for the vastly hostile environment just beyond the Station takes a looooong time. It requires hours of carefully rehearsed procedures, precise gestures, and endless checks to make sure everything is ready before the hatch opens.

For this EVA-95, I had the privilege of leading the intravehicular (IV) operations, and I couldn't be happier of how well we worked together. While strictly following all procedures, we still managed to get Jessica and Chris into the airlock about 30 minutes ahead of schedule. That may not sound like much, but for the crew members in the suit, it’s 30 minutes of energy saved for the EVA marathon ahead, a huge advantage!

Next EVA on August 6! As usual, you can watch it live on the NASA website or on their YouTube channel.

[French] Jour 167, orbite 2587 – C’est si facile dans les films d’enfiler un scaphandre et de sortir du vaisseau spatial… Dans la vraie vie, préparer deux astronautes et leurs scaphandres à affronter l’environnement extrêmement hostile qui règne juste à l’extérieur de la Station prend un trèèèès long moment. Des heures de procédures soigneusement répétées, de gestes précis et de vérifications pour s’assurer que tout est prêt avant l’ouverture de l’écoutille.

Pour cette EVA-95, j’avais la joie de diriger les opérations intravéhiculaires, et nous avons formé une équipe super efficace. Tout en suivant strictement toutes les procédures, Jessica et Chris étaient dans le sas, prêts à sortir, avec 30 minutes d’avance. 30 minutes, ce n’est pas grand chose, mais pour les membres d’équipage dans le scaphandre, c’est toujours 30 minutes d’énergie économisée pour le marathon que représente une EVA !

Prochaine sortie extravéhiculaire le 6 août! Elle sera comme d’habitude retransmise en direct par la NASA sur leur site et sur leur chaîne YouTube.

[English] Day 165, orbit 2557 — GEARS (Genomic Enumeration of Antibiotic Resistance in Space) is another experiment making good use of the Life Sciences Glovebox, a sealed laboratory workspace where we can safely handle biological samples.

You've probably already heard about antibiotic-resistant bacteria, which are a growing threat to human health on Earth and a leading cause of hospital-acquired infections. The surfaces of the International Space Station have been monitored since 2000, and two common bacterial species found on board have shown resistance to antibiotics, as well as tolerance to desiccation, starvation and disinfection.

This could pose challenges during future long-duration exploration missions, when spaceflight-weakened immune systems may leave astronauts more vulnerable to infection while crews must rely on a limited supply of antibiotics carried on board.

But it also gives researchers a unique opportunity to study how these microorganisms survive and adapt in extreme environments… This knowledge could help safeguard astronaut health and improve healthcare here on Earth as well. Go science!

[French] Jour 165, orbite 2557 — L’expérience GEARS (pour Genomic Enumeration of Antibiotic Resistance in Space) met elle aussi à profit la boite à gants Life Sciences Glovebox, un espace de laboratoire fermé qui nous permet de manipuler des échantillons biologiques en toute sécurité.

Vous avez probablement déjà entendu parler des bactéries résistantes aux antibiotiques. Elles représentent une menace croissante pour la santé sur Terre et figurent parmi les principales causes d’infections nosocomiales. Les surfaces de la Station spatiale internationale sont sous surveillance depuis l’an 2000, et deux espèces bactériennes couramment présentes à bord ont montré une résistance aux antibiotiques, ainsi qu’une tolérance à la dessiccation, à la privation de nutriments et aux procédures de désinfection.

Il s’agit d’un défi supplémentaire à relever pour les futures missions d’exploration de longue durée. Le système immunitaire des astronautes, affaibli par le séjour dans l’espace, pourrait les rendre plus vulnérables aux infections, alors même que les équipages ne pourront compter que sur un stock limité d’antibiotiques...

Mais cette situation offre aussi aux chercheurs une occasion unique d’étudier comment ces micro-organismes survivent et s’adaptent à des environnements extrêmes – des connaissances qui pourraient contribuer à protéger la santé des astronautes, et améliorer les soins sur Terre. Vive la science !
