Fun fact: The main engine behind the boost to the moon flew before on six Space Shuttle Atlantis missions. The European Service Module has 33 engines, but this is the only one capable of sending the Orion spacecraft towards the Moon, some 380 000 kilometres away.

🌚 We’re halfway there. At the time of posting this (02:00 UTC), the Artemis II mission is about halfway to the Moon. When the astronauts arrive, they will conduct a lunar flyby and collect scientific observations of the Moon’s surface.

Artemis II Science Officer, reporting for duty. 🚀 There’s a new “SCIENCE” seat in the main NASA Artemis flight control room. Yesterday, Kelsey Young of NASA’s Goddard Space Flight Center became the first person to step into this role during an Artemis mission. The Science Officer represents a whole community. Just one floor away, in a backroom at Mission Control, the Artemis II Lunar Science Team is hard at work. They have been preparing for this moment – and getting astronauts ready for Moon observing missions – for years. They’ve led training expeditions to Earth's most Moon-like places, custom-built lunar geology classes, worked out the fine points of photographing the Moon from space, and spent countless hours in mission simulations. Now, together with the crew and flight controllers, they’re not just helping Artemis II reach its full science potential—they’re laying a strong foundation for future missions.

You've seen his visualizations. Now, meet the man who knows the far side of the Moon like the back of his hand. Ernie Wright maps the Moon, which comes in handy when training NASA Artemis astronauts to see parts of the lunar surface humans have never laid eyes on before.

Artemis II update: our European Service Module's main engine performed the translunar injection so precisely that flight controllers in Houston decided to cancel the first of three outbound trajectory correction burns on the way to the Moon🥳 Source: @esaspaceflight @EverythingScience

Lights, camera… lunar action. 📸🌕 For Artemis II, Orion will carry 31 cameras designed to capture the mission from every angle. From external cameras mounted on the solar arrays to internal cabin views documenting crew life, these imaging systems will record key moments like launch, solar array deployment, and the spacecraft’s distant journey around the Moon. A dedicated optical navigation camera will photograph Earth and the Moon to help Orion determine its position in deep space, while handheld Nikon Z9 cameras give the crew the ability to capture high‑resolution imagery through the windows.

In this image, also taken from the Orion capsule, we see the divide between night and day, known as the terminator, cutting across Earth. Whether awake or dreaming, we're all here on this planet together. Source: @NASA @EverythingScience

These two images were taken by Reid Wiseman only minutes apart. The stark difference is the result of camera settings. In the first, a longer shutter speed let in much more light from Earth, while the shorter shutter speed in the second emphasizes our planet's nighttime glow. Source: @NASA @EverythingScience

That's us! 🌍 The Artemis II crew captured beautiful, high-resolution images of our home planet during their journey to the Moon. As Christina H Koch put it: "You guys look great."

This lets faint details like the aurora, stars and the sodium layer show up without over exposing the planet. Source: @DJSnM @EverythingScience

“I’m the space plumber, I’m proud to call myself the space plumber.” Mission specialists like Christina H Koch train for all roles so they can jump in wherever they’re needed. Sometimes that means fixing vital machinery, like the spacecraft toilet. Source: @NASA @EverythingScience
