If you’ve ever scrolled through Instagram or TikTok and spotted that iconic, swirling shot of Earth floating in the blackness of space—you know, the one that looks like a priceless marble draped in clouds and blue oceans—chances are good you’ve stopped to double-take. That’s the Blue Marble photo, and it’s more than just a pretty space pic. For folks like me, who work as a Blue Marble supplier, it’s a core part of how we bring that iconic image to homes, offices, and creative projects everywhere. But if you’re new to sharing it on social media, you might be wondering: how do I do it right? Not just to post a cool space snap, but to honor the photo’s legacy, stay on the right side of copyright, and maybe even tell its story in a way that resonates with other space lovers? Blue Marble
Let’s start with the basics I learned early on as someone who’s supplied Blue Marble prints and digital assets for over a decade: the Blue Marble isn’t just one photo. There are two main NASA versions most people know, and understanding which one you’re working with is the first step to sharing it well. The original 1972 Blue Marble was taken by the Apollo 17 crew, a handheld shot captured by astronaut Harrison Schmitt as he looked back at Earth on their way to the Moon. That’s the grainier, more “vintage” version many people associate with early space exploration. Then there’s the modern NASA Blue Marble, first released in 2002 and updated regularly, which is a composite of thousands of satellite images stitched together to give a hyper-detailed, almost photorealistic view of the entire planet, even showing tiny details like dust storms over the Sahara or coral reefs in the Great Barrier Reef. As a supplier, I often work with both—supplying high-resolution scans of the Apollo 17 version for nostalgic art prints and updated satellite versions for educational use.
Now, the big question for social media: is the Blue Marble even free to share? That’s where most people stumble, especially since it’s such a recognizable image. I learned a long time ago that all NASA imagery, including the Blue Marble, is in the public domain in the United States. That’s a huge win for anyone wanting to post it—but that doesn’t mean you can just pull a blurry, 10-year-old screenshot from Google and call it a day. Here’s where I see a lot of people (and even some small businesses) go wrong: Google Images is full of low-res, watermarked, or cropped versions of the Blue Marble that aren’t actually the official, high-quality files from NASA. When I supply my customers, I always make sure to point them to the right sources for authentic assets, because sharing a blurry, uncredited screenshot doesn’t do the Blue Marble justice—and it can even lead to accidental copyright issues if someone tries to sell that blurry copy later.
So, step one for sharing the Blue Marble on social media: get your source right. If you’re looking for digital copies, NASA’s own Earth Observatory website is the best place to start. They host all official Blue Marble versions, from the 1972 shot to the latest 2023 updates, for free download, and they even have different sizes for every social platform—so you don’t have to stretch a square image into a Reel and ruin the detail. I always tell my customers who order prints from me to grab their digital files there too, because it’s the only way to get the crisp, high-res versions that make the Blue Marble look like art, not a grainy phone snap. For the vintage 1972 Apollo version, you can also check the NASA Johnson Space Center’s archives; they have higher resolution scans than the original NASA Earth Observatory had for years, which is why many art collectors prefer that version for their walls.
Next, think about how you’re actually sharing it. Social media isn’t just about posting a picture and moving on—its algorithm thrives on context, and the Blue Marble has a powerful story that most people don’t know. As a supplier, I’ve found that posts that tell a quick, honest story about the Blue Marble get way more engagement than just a plain photo. For example, if you’re posting the 1972 Apollo shot, you could write: “This is the original Blue Marble, taken by Apollo 17 astronaut Harrison Schmitt in 1972. It’s one of the most reproduced space photos ever, and I supply high-quality prints of this shot for anyone who wants a piece of space history on their wall.” If you’re posting the modern composite version, you could mention: “This is the 2023 Blue Marble, stitched from over 10,000 satellite images to show every corner of our planet. It’s a reminder of how small and interconnected we all are.” That small bit of context turns a random space post into something meaningful, and it also helps distinguish your post from the millions of generic space snaps out there.
One thing I always emphasize to anyone sharing the Blue Marble is to credit the right people. Even though the image is public domain, NASA requires (and it’s just good manners) to credit the source when you share it. Most social platforms make this easy: on Instagram, you can tag NASA’s official Earth account when you post; on TikTok, you can add a text overlay that says “Image: NASA Earth Observatory” or “Image: NASA Johnson Space Center”; on X (formerly Twitter), you can mention @NASA_EO in your post. As a supplier, I also make sure that every print I sell has a small, unobtrusive credit line on the back, because it helps honor the work that goes into creating and capturing these images. I’ve had customers tell me that adding that credit line makes their print feel more valuable, because it’s not just a pretty picture—it’s a piece of space history.
Now, what if you’re a business, like me, that supplies Blue Marble products, and you want to share those on social media? There’s a right way and a wrong way to do this, and I learned that the hard way when I first started. A few years back, I posted a photo of a Blue Marble print I sold to a customer, with a quick “Check out our Blue Marble prints!” in the caption. The post got almost no engagement, and I realized why: it was just a sales pitch, with no context, no story, and it looked like every other generic art post on the feed. So I changed my strategy. Now, when I share my Blue Marble products on social media, I pair each post with a fun, relatable fact—like “Did you know the Apollo 17 Blue Marble has been used in everything from school textbooks to movie sets?” or “Our latest Blue Marble print is made with archival paper that will last for generations, just like the original image.” I also share behind-the-scenes content: photos of me packing prints, or a time-lapse of a customer unboxing their Blue Marble. That makes the post feel personal, not salesy, and it’s way more likely to get likes, shares, and inquiries.
Another big tip I can offer is to tailor your post to the platform you’re using. What works on Instagram won’t work on TikTok, and what works on X won’t work on Pinterest. Let’s break it down, since I’ve tested all of these over the years:
Instagram: This is the best platform for Blue Marble photos, because it’s visual and has a big audience of space and art lovers. For Instagram, I recommend posting a high-quality square or horizontal photo of the Blue Marble, either the full shot or a close-up of a section (like the African coast or the Pacific Ocean) for a more unique look. Add a caption that’s 1-2 paragraphs: start with a quick hook, add context about the image, and end with a subtle call to action. For example: “If you’re looking to bring a little piece of Earth’s beauty into your home, our Blue Marble prints come in sizes from small desk art to large wall pieces. Tag a friend who’d love this!” You can also add relevant hashtags, but don’t go overboard—stick to 5-10, like #BlueMarble, #SpaceArt, #NASAImages, #EarthPhotography. Hashtags like #WallArt or #HomeDecor will help reach people looking for art, while #SpaceLovers will help reach the core space audience.
TikTok/Reels/Shorts: Short-form video is huge, and the Blue Marble is perfect for this. You don’t need to make a fancy video—even a 15-second clip of zooming in on the Blue Marble, with a voiceover or text overlay that says “The Blue Marble has been inspiring people for 50 years. Here’s why it’s still my favorite space photo,” works. I’ve also had success with “before and after” Reels: showing the grainy original 1972 photo next to the sharp 2023 version, explaining how NASA’s satellite technology has improved over time. The key here is to keep it short, engaging, and to the point—no long captions needed, just the facts and a call to action like “Find high-res Blue Marble prints at my shop (link in bio)”.
X (Twitter): X is great for quick, shareable facts about the Blue Marble. Here, you don’t need a huge photo—just a clear, high-res image, paired with a 1-sentence fact and a link to your products if that’s relevant. For example: “The original Blue Marble was taken 51 years ago today by Apollo 17. It’s still one of the most iconic images of Earth ever taken. We supply museum-quality prints of both the 1972 and 2023 versions → [link]”. X users love facts, so adding a quick stat (like “51 years ago” or “10,000 satellite images”) will make your post more engaging.
Pinterest: Pinterest is all about inspiration, so this is the best platform for people looking to buy Blue Marble prints or use the image for creative projects. On Pinterest, post a high-res, vertical photo of the Blue Marble (or a styled photo of the print hanging on a wall), and a detailed caption that tells people exactly what it is and how they can use it. For example: “Bring cosmic beauty to your living room with a museum-quality Blue Marble print. Available in 8 sizes, ready to hang. Perfect for space lovers, educators, or anyone who loves unique wall art.” Pinterest users search for specific things, so using keywords like “Blue Marble print”, “space wall art”, “NASA art” will help your post show up in their searches.
Now, what about common mistakes to avoid? Let’s talk about the biggest ones I see as a supplier:
First, don’t use blurry or uncredited images. As I mentioned earlier, there are tons of low-res, watermarked versions of the Blue Marble online, and using them not only looks unprofessional, but it can also get you in trouble if someone tries to use that image for commercial purposes. Always use official NASA sources, and always credit. Second, don’t overdo the edits. The Blue Marble is beautiful on its own, so adding heavy filters or cropping out key parts (like Africa or Antarctica) can ruin its impact. A light contrast or brightness tweak is fine, but don’t turn it into something it’s not. Third, don’t make your post only about selling. If you’re a business sharing Blue Marble content, balance sales posts with educational or engaging content. For example, I’ll post a fun fact about the Blue Marble one week, then a photo of a customer’s print in their home the next week, then a sales post the third week. That keeps your audience engaged, not overwhelmed with ads. Fourth, don’t forget accessibility. A lot of people use screen readers on social media, so adding alt text to your Blue Marble post is important. The alt text should be descriptive: “A high-resolution photograph of Earth, the Blue Marble, from space, showing the Atlantic Ocean, Africa, and clouds swirling over the planet’s surface, taken by NASA satellites”. That helps everyone enjoy your post, regardless of how they’re using social media.
I’ve been a Blue Marble supplier for 12 years now, and over that time, I’ve seen the Blue Marble go from a niche space photo to a global cultural icon. It’s been on billboards, in movies, in classrooms, and in millions of homes. The best part about sharing it on social media is that you’re not just posting a picture—you’re passing on that same wonder that the Apollo 17 crew felt when they looked back at Earth, or that the NASA scientists felt when they stitched together the modern version. Whether you’re posting it as a hobby, for your small business, or as an educator, following these steps will help you share the Blue Marble in a way that honors its legacy, engages your audience, and stays on the right side of the rules.
