The Artemis II mission has produced stunning high-resolution images of Earth from space, crew training moments, and spacecraft details that NASA has made freely available to the public. Why settle for generic desktop wallpapers when you can have actual photos from humanity's return to the Moon as your background?

NASA's image library contains hundreds of Artemis II photos in resolutions high enough for any monitor. Downloading and setting them as your Windows wallpaper takes less than a minute.

Not heard of Artemis II?

It's NASA's landmark mission marking the return of humans to lunar orbit for the first time since 1972, and it's kind of a big deal. The four-person crew of Reid Wiseman, Victor Glover, Christina Koch and Canadian Space Agency astronaut Jeremy Hansen have flown further from Earth than any humans have travelled in over 50 years.

The mission sees the crew orbit the Moon aboard the Orion spacecraft before returning home, a journey of around 10 days in total.

How to make Artemis II photos your background

1. Download images from NASA's library

First, go to the page containing NASA's lunar library — official Artemis II image collection with photos in multiple resolutions. Browse the gallery and choose the image you want to download, then download it.

2. Set the image as your Windows wallpaper

Navigate to where you downloaded the image (usually your Downloads folder). then right-click on the image file and select "Set as desktop background."

The image immediately becomes your wallpaper. If it looks stretched, distorted, or doesn't fit your screen properly, you need to adjust the fit setting.

Type "desktop" into the Windows search menu and open "Choose your desktop background" from the results.

Scroll down until you see "Choose a fit" with a dropdown menu. Try "Fill" first — this scales the image to cover your entire screen while maintaining aspect ratio. If parts of the image get cut off, try "Fit" instead, which displays the entire image without cropping but may leave black bars on the sides.

Experiment with both options to see which looks better for your specific image.

3. How to set the image as your Mac wallpaper

After downloading the image on macOS 26, right-click it and select Set Desktop Image — it will update as your wallpaper instantly.

To fine-tune how it displays, head to System Settings and select Wallpaper from the sidebar. From there you can adjust whether the image fills or fits your screen, and if you're running multiple monitors, you can control whether the same wallpaper carries across all your spaces with a single toggle.
