On this day in 1998, two modules, the Russian Zarya and American Unity, were joined in Earth orbit to create the International Space Station (ISS).

The ISS was built by five space agencies involving 15 nations. NASA notes that 273 people from 21 countries have visited the ISS over the years to assist with more than 3,300 research and educational investigations. The station has been busy, and pretty expensive at more than $150 billion to design and build.

Back in 2012, Astrophysicist Neil DeGrasse Tyson stated:

If the United States commits to the goal of reaching Mars, it will almost certainly do so in reaction to the progress of other nations – as was the case with NASA, the Apollo program, and the project that became the International Space Station.

Eleven years later, the ISS continues to orbit the Earth while plans are still being made to return to the Moon and visit Mars. Maybe Dr. Tyson was right given our current race with China to the Moon. We sometimes need that extra push to move towards the stars (as least in terms of crewed flights).
