The history of the National Science Foundation Network, a precursor of the internet

Although ARPANET connected various national laboratories and supercomputing facilities by the 1970s to facilitate scientific collaboration, the system was slow and required highly trained operators. The launch of NSFNET in 1986 provided a more flexible and powerful network that went on to connect over 170 academic and research communities and link to its European counterpart, EASInet.

Unlike hot air balloons lifted for hours by heating air, NASA's scientific balloons use helium to lift payloads of up to 3,600 kilograms (8,000 pounds) for up to six weeks at a time.

The history of the commercialization of the internet, from ARPANET to NSFNET and beyond

NSFNET was launched in 1986 by the National Science Foundation as the first network available to all researchers, connecting them to a system of supercomputer facilities. Despite growing from 2,000 computers in 1985 to 2 million by 1993, the rapid expansion of commercial internet services led to NSFNET's decommissioning by 1995.

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.
