Here is the first successful landing of an orbital-class rocket booster. The SpaceX employees pictured are really excited because getting to Mars on the cheap requires major re-usability, and this was a major milestone in that little project.
“This photograph was taken with a Nikon D7100 and Tokina 11-20mm lens. It’s a composite of three separate images. One image contains the initial launch burn, one contains the boostback burn, and the final image contains the re-entry and landing burns. Taking three separate images makes the final image cleaner; there’s less noise.”
