See the unbuilt rocket design that would have dwarfed the Saturn V

Designed in the early 1960s, the Sea Dragon was a radical concept for an ocean-launched rocket that would have far exceeded the Saturn V in size and payload. The conceptual design was ultimately too risky and impractical to build.

The Russian Federal Space Agency enabled the first space tourism journey

NASA refused to take Dennis Tito, who had no formal training as an astronaut, up to the International Space Station. Instead, the American engineer and entrepreneur traveled aboard the Soyuz TM-32 mission and described the initial experience of microgravity after engine shut-off as the "most spectacular" part of the flight.

A 1983 NATO war simulation provoked the Soviets to prepare for war

The "SNAFU" podcast, hosted by actor and comedian Ed Helms, explores some of the biggest blunders in history. Season one focuses on the 1983 NATO Able Archer military exercise, a war game that simulated nuclear attacks on the Soviet Union. The USSR mistook the exercise for a genuine threat and prepared its forces for war. Helms recounts this almost catastrophic event in world history with his signature humor.

The unloading and maneuvering of the space shuttle's payload were accomplished by the Shuttle Remote Manipulator System—a robotic arm designed and constructed in Canada, which led to it being colloquially known as the Canadarm.

The Columbia disaster contributed to the end of the Space Shuttle program and NASA's reliance on commercial partners such as SpaceX and Boeing to transport astronauts and cargo.

The origin of atmospheric science while testing nuclear weapons during the Cold War

The arms race between the US and the Soviet Union saw both countries stockpiling and detonating hundreds of bombs underground, underwater, and in the atmosphere. To better predict where nuclear fallout would travel after these tests, scientists developed models that would serve as a foundation for those used to explain atmospheric circulation.
