The system initially started to capture archival footage of important space events for NASA managers and engineers and expanded as public interest grew. The Apollo 8 Christmas Eve broadcast while in orbit around the Moon was received by more than a billion people. [ 272 ]
On July 14, with the successful encounter of Pluto by NASA's New Horizons spacecraft, the United States became the first nation to explore all of the nine major planets recognized in 1981. Later on September 14, LIGO was the first to directly detect gravitational waves.
There are several types of timeline articles. Historical timelines show the significant historical events and developments for a specific topic, over the course of centuries or millennia.

November 2020 NASA:ODPO Space junk as product and form of human presence in space has existed ever since the first orbital spaceflights and comes mostly in the form of space debris in outer space. Space debris has been for example possibly the first human objects to have been present in space beyond Earth, reaching its escape velocity after ...
