World Space Week

World Space Week is observed in October, beginning on the 4th of the month and continuing until the 10th. It’s an international celebration of the science and technology that has taken humankind to the edge of space and beyond.

Every year, a theme is developed for this week that highlights a particular area of space exploration. For example, in 2021, the theme was “Women in Space.” This is a great week for people to take the time to reflect on the history of space exploration and to look forward to the future.

The History Of World Space Week

World Space Week was created on December 6th, 1999 when the UN General Assembly declared it to be an annual event that’s celebrated from October 4th through October 10th. These two dates were chosen because of their importance to space history.

October 4th was the launch of the first human-made satellite, Sputnik 1, in 1957. October 10th was when the Outer Space Treaty was signed in 1967. In October of 2000, this week was observed for the first time and has been celebrated ever since. By 2019, it was observed in 96 countries.
