ESA mission control will guide @ESASolarOrbiter through a close encounter with Venus tonight. The gravity assist manouevre will 'tilt' the spacecraft's orbit around the Sun and grant it a unique view of our star's enigmatic polar regions. 🕵️‍♀️ ☀️

The women behind Solar Orbiter’s successes!

[ESA's Solar Orbiter @ESASolarOrbiter]

💫🎉 Behind every successful ESA space mission, there is a woman. Behind Solar Orbiter, there are more than a hundred of them!

Yesterday, we celebrated our 5th launch anniversary - Join us today in celebrating these women who make our mission a success, on international day of women and girls in science!

DYK? At ESA we have multiple space missions and instruments studying the Sun, because learning about our star is key to predicting its potentially hazardous activity. 1/3

Difficult to put into words how incredible this pic is. BepiColombo's first ever photo of Mercury's south pole (top right of planet). It was taken 23 minutes after closest approach at a distance of 3500 km.

Set to launch in 2031, #Envision will observe Venus from its inner core up to its upper atmosphere, to further reveal the planet's history, activity and climate.

[ESA's Solar Orbiter @ESASolarOrbiter]

A #SolarOrbiter success story!
A key mission goal was to link the solar wind detected around the spacecraft back to its source regions on the Sun.
A new paper, using data taken during our first close approach to the Sun, confirms that it's possible.

☀️🌬️ We're a step closer to figuring out the mysterious origin of the 'slow' solar wind, thanks to data collected by @ESASolarOrbiter during its first close approach to the Sun.

The ESA/JAXA BepiColombo mission to Mercury has experienced a technical issue that is preventing its thrusters from operating at full power.

Top spaceflight experts from ESA and its partners are working the problem, but the long-term impact on the mission is uncertain.

🌄 Si vous avez levé les yeux vers le ciel la nuit dernière, un peu partout dans l’hémisphère nord, vous avez sûrement eu le spectacle de votre vie 🤩. Et si (comme
moi 😭) vous l’avez raté, voilà quelques beaux clichés parmi les milliers qui ont circulé sur les réseaux. En temps normal, les aurores se produisent plutôt dans les régions polaires, elles sont causées par l'interaction entre les particules émises par le soleil, et l’atmosphère et le champ magnétique de la Terre 🧲🌍. 1/3

DYK? @ESASolarOrbiter and NASA-led Parker Solar Probe have recently joined hands to study the solar wind.

[European Space Agency @esa]

Spiders on Mars?

No, these dark spots, seen by ESA’s Mars Express on the outskirts of an area nicknamed 'Inca City' in the southern polar region of Mars, have a more 'down to Earth' explanation...

[ESA Science @esascience]

Since beginning science operations in 2004, #MarsExpress has provided countless breathtaking views of the Red Planet🔴 Below four examples:

1⃣ Ius and Tithonium Chasmata on Mars
2⃣ Utopia Planitia on Mars
3⃣ The terrain surrounding Mars’s north pole.
4⃣ Landslides and rockfalls around Olympus Mons

#ESAJuice will also target the most volcanically active body in the Solar System, Io.

🌋 On this world, volcanoes soar up to around 18 km in height, and eruptions can last years.

Juice will monitor Io’s volcanic activity and investigate what its surface is made of 👉 https://t.co/eb2HbJTzTI

🧐☄️Can you spot the comet in this photo of #SolarEclipse2024?
Found in @MissionSoho data just hours earlier, the doomed comet was visible during the eclipse before it met its demise.
