Spectacular high-resolution image of our home planet viewed through the Orion Crew Module window by the Artemis II astronauts as they continue their journey to the Moon on Flight Day 2, 3 April 2026 (pic: NASA)

A full disc image of Earth, as seen from the Orion Crew Module. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. At lower left, a large brown landmass is Africa, with Spain and Portugal with twinkling lights where the planet curves. At top right, auroras glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space (pic: NASA/R.Wiseman)

😮 Awesome views from Day 2 of #Artemis II this morning.

Artemis II launching tomorrow!!?? So exciting!

Happy launch anniversary, Columbus! 🥳

18 years ago today, @esa.int's Columbus laboratory ascended to orbit, nestled in Space Shuttle Atlantis.

This engineering & scientific marvel became the first permanent European research facility in space.

Silver is back with a blog post on the new orbital mechanics. It’s a bit technical, but it provides a glimpse into the deeper workings of Orbital Dawn.

orbitaldawn.com/posts/2026-1...

An orbital simulation is coming to Orbital Dawn! This will enable delta-V calculations and realistic timetables for spacecraft transit time.

Development is getting back on track! Currently working on power production and consumption. Next task will be revisiting supply usage and contingency plans in case supplies are depleted.

🛰️ Preparing for liftoff – the next Galileo satellites have been mounted to their Ariane 6 dispenser that will eject them from the rocket's upper stage into their initial orbit around Earth.

Congratulations to Blue Origin for a successful launch and booster recovery! Excited to see the ESCAPADE mission unfold as well.

Blue Origin are live with the second attempt to launch ESCAPADE to Mars, and maybe land the New Glenn booster.

A #CosmicVision mission, #ESAJuice is en route to Jupiter.

Juice successfully performed the world's first Lunar-Earth flyby in 2024, followed by a Venus flyby this year. The spacecraft is now on track to swing by Earth two more times and arrive at Jupiter in July 2031. 1/ #CM25

Exactly 25 years ago, at 09:21 UTC, the era of continuous human presence on the International @Space_Station began.

Since Crew One took up residence in 2000, 21 @esa.int astronauts have lived and worked on this orbital outpost, conducting essential research to benefit life on Earth.

Exciting to see another Ariane 6 launch soon!

Close-up of NASA’s Orion spacecraft for Artemis II, showing NASA and ESA logos. Several hoses and cables are connected to the spacecraft, and part of the transport vehicle is visible.

Wide view of the Orion spacecraft for Artemis II being transported near a large industrial building with bright interior lighting. The grassy foreground contrasts with the industrial setting, and various vehicles and equipment are visible under a partly cloudy sky.

Orion on a roll 🌀
Last week, the Artemis II Orion - complete with crew module 👩‍🚀, @esa.int's European Service Module ⚡, solar arrays ☀️ + launch abort system 🛡️ - was rolled 10km to the Vehicle Assembly Building at NASA's Kennedy Space Center.
Next step - stacking on the SLS rocket 🚀

‪🆕 Researchers combed through images from ESA's #MarsExpress and #ExoMars spacecraft to find 1039 swirling dust devils 🌪️

Using these dust devils to track raging winds on Mars, their findings include that the strongest winds blow much faster than we thought!🧪🔭

Today, @esa.int's Columbus lab on the International Space Station circled Earth for the 100,000th time🎉

During that time, we’ve seen:
🧳4.26 billion km travelled
🧪250+ experiments
👩‍🚀16 ESA astronauts
🥼75 m³ of lab space
🕣19,280 shifts run by the Columbus Control Centre

A blue and black sky filled with brilliant stars covers the upper two-thirds of the vertical image. The stars are different sizes and shades of white, beige, yellow, and pale orange. Across the bottom third of the scene is a craggy, mountain-like vista of dust and gas with spire-like peaks and deep, misty valleys. The peaks appear in varying shades of orange, yellow, and brown. Above their soaring spires is a wispy, ethereal white cloud that stretches horizontally across the scene. What looks like steam appears to rise from the mountaintops and joins this cloud. At the top right corner, a swath of orange and brown structure cuts diagonally across the sky.

What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and ultraviolet light of nearby, massive, infant stars. What else did #NASAWebb find in Pismis 24? https://bit.ly/4mr3cmt

ESA and JAXA advance potential Apophis mission collaboration The Japan Aerospace Exploration Agency (JAXA) has requested funding to participate in the European Space Agency’s (ESA) Rapid Apophis Mission for Space Safety (Ramses).

We welcome #JAXA's interest in participating in the Ramses mission to the asteroid #Apophis, which will make a safe but exceptionally rare and scientifically valuable flyby of Earth in April 2029.

Liftoff of Ariane 6 flight #VA264 launching Metop-SG-A1 and Copernicus Sentinel-5A to orbit!

🚀 Next launch incoming...

Join us live tonight (or early morning) for the next Ariane 6 flight #VA264 that will launch Metop-SG-A1 and Copernicus Sentinel-5 into orbit from 01:10 BST/02:10 CEST on esawebtv.esa.int

📅 Liftoff schedule at 01:37 BST/02:37 CEST.

The Rosetta mission found that the comet’s water was more rich in heavy water than Earth’s oceans, suggesting that Earth’s water was not deposited by comet impacts.

Today is the 11th anniversary of the Rosetta spacecraft entering orbit around comet 67P/Churyumov–Gerasimenko. Rosetta and its lander Philae greatly expanded our knowledge of comets and of the origin of water on Earth.

Meet Startrain and Startrain Express, the heavy launch system for taking crew to the Moon, Tiris and beyond! How far would you like to go?

A long, smoky, greyish-blue cloud in the centre of the image curves in an arc around three bright stars, each with long cross-shaped diffraction spikes. The cloud is lit more brightly on the inner side facing the stars, and fades into the dark background on the outer side. A few other stars and points of light surround the cloud: one small star below it has a dark band crossing its centre.

📷 This NASA/ESA #Hubble Space Telescope image shows reflection nebula GN 04.32.8. Reflection nebulae are clouds of dust that don't emit their own light, as other nebulae do. Instead, light from nearby stars scatters off their dust, lighting them up.
