CosmicRamiA while back (around seven months ago) I posted an image of ISS (first image), but captured FROM ABOVE (higher orbit). This is the work of Aussie company HEO!This type of work is really fascinating as things (like satellites) are all moving at high velocities up there (28,000 km/h) - so other things (like other satellites or space stations) zip past quickly. You would then need to 'de-zip' the object to make a crisp clear image.Well, they've done it again.This time, imaging the Chinese Space Station (second image) from a distance of 83 kilometres (resolution of 0.17 m/px) 🤯This is really cool stuff. I promise.📸 BlackSky / HEO<a href="https://aus.social/tags/Space" class="mention hashtag" rel="nofollow noopener" target="_blank">#Space</a> <a href="https://aus.social/tags/EarthObservation" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarthObservation</a> <a href="https://aus.social/tags/SpaceStation" class="mention hashtag" rel="nofollow noopener" target="_blank">#SpaceStation</a> <a href="https://aus.social/tags/Astrodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#Astrodon</a>
