When we think of space exploration, we often picture powerful rockets, solemn astronauts, and breathtaking images of distant planets. But the truth is, some of the most memorable milestones in space history are the downright puzzling ones. Over the decades, scientists, engineers, and explorers have carried out missions that sound more like science fiction pranks than serious research. Here are 12 weird space missions that you may have never heard about, but won’t forget once you do.
12. Project Echo (1960-1964)
Project Echo aimed to put giant metallic balloons into orbit to bounce radio signals across continents. While the concept worked briefly, the balloon-satellite idea quickly became obsolete as better communications technology emerged.

11. Space Archaeology for Lost Satellites (Ongoing)
Scientists now practice “space archaeology,” tracking and studying long-forgotten satellites from the early days of the space race. These relics orbit as artifacts of humanity’s first steps into the cosmos.

7. Russia’s Animal Test (1950s–1960s)
Before sending humans, the Soviet Union launched a bunch of animals into space, including dogs, mice, rabbits, tortoises, and even a menagerie of insects, to test survival in orbit. Laika the dog remains the most famous of these pioneers.
6. John Young’s Corned Beef Sandwich (1965)
On Gemini 3, astronaut John Young smuggled a corned beef sandwich into the spacecraft. NASA wasn’t amused but the stunt became one of the most legendary space pranks and weird space missions in history.
