If there’s one thing you can guarantee from a NASA space mission, it’s stunning photography. Now that a huge album of high-resolution images have been sent back to Earth by the Artemis II astronauts, you can pick an amazing new wallpaper for your phone, computer and other devices.
Here’s how to make sure you’re getting the best possible wallpaper image quality for iPhone, Android, PC and Mac.
The Flickr website lets you download NASA images in various resolutions

The photos from the Artemis II mission are appearing on the NASA Johnson Flickr account. The images are being made available elsewhere, including on the NASA website, but Flickr makes it easy to download the highest resolution images, which is what you’ll want if you’re using them for a desktop wallpaper on a computer screen.
Once you’ve decided which of the astonishing images you want for your wallpaper (my personal favourite is A Setting Earth, shown above), click on the down arrow that appears beneath the images. You should now see a pop-up menu with the various download sizes available. This particular image goes all the way up to 5,568 x 3,712 pixels, which is more than enough for even the biggest desktop monitor.
Even if you’re planning to use the image on a display with a much lower resolution, you might as well pick the highest resolution image, as the file sizes are modest. The highest resolution version of A Setting Earth is only a 2.3MB download, for example.
You don’t need to worry about infringing any copyright by using the images. The NASA Flickr page states: “These official NASA photographs are being made available for publication by news organizations and/or for personal use printing by the subject(s) of the photographs.” The only restriction is that they must not be used for advertisements, products or promotions.
On a Windows PC, right-click on the downloaded image in Windows Explorer and choose Set As Desktop Background.
If the image looks distorted, type “desktop” into the Windows search menu and open the Choose Your Desktop Background setting that should appear in the results. Scroll down and you should see an option to choose a fit for the image. Fill or fit are normally the two best options and worth experimenting with.
In macOS 26, right click on the downloaded image and choose Set Desktop Image. The image should appear straight away as your desktop wallpaper.
On Mac, you can tweak with the wallpaper settings by opening System Settings and then choosing Wallpaper from the left-hand menu.
Here you can choose whether to fill or fit the image, and if you’ve got multiple screens you can choose whether you want the same wallpaper to appear across all your “spaces” by clicking the relevant button.
On the iPhone things are a tad more convoluted. Once you’ve downloaded the image from the NASA website, open the Files app and click on your image in the Downloads folder. Then press the up arrow button and select Save Image.
Now open the Settings app and choose wallpaper, and then select the image from your photos. Most of the NASA images are in the landscape aspect ratio, so you may need to do some repositioning of the image to make it work nicely as an iPhone wallpaper.
Once you’ve downloaded the image, open the Wallpaper menu from your Settings app. This app varies from handset to handset, but you’re normally able to pick a wallpaper from your own photo album. On a Google Pixel, I had to press More Wallpapers then More Photos before I was allowed to pick the image saved in my downloads folder.
You can choose whether you want to save the Artemis II image as your wallpaper, lock screen or both.
