This is a timeline of space exploration which includes notable achievements, first accomplishments and milestones in humanity's exploration of outer space.. This timeline generally does not distinguish achievements by a specific country or private company, as it considers humanity as a whole.

Government space agencies, established by governments of countries and regional agencies (groupings of countries) are established as a means for advocating for engaging in activities related to outer space, exploitation of space systems, and/or space exploration. The listings summarize all countries' and regional authorities' space agencies ...
Space exploration also gives scientists the ability to perform experiments in other settings and expand humanity's knowledge. [67] Another claim is that space exploration is a necessity to humankind and that staying on Earth will eventually lead to extinction. Some of the reasons are lack of natural resources, comets, nuclear war, and worldwide ...
Columbus Module at the International Space Station, launched into space on the U.S. Space Shuttle mission STS-122 in 2008. The following outline is provided as an overview of and topical guide to space exploration. Space exploration – use of astronomy and space technology to explore outer space. [1]
Notable test flights of spaceflight systems may be listed even if they were not planned to reach space. Some lists are further divided into orbital launches (sending a payload into orbit, whether successful or not) and suborbital flights (e.g. ballistic missiles, sounding rockets, experimental spacecraft).
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.
This led to a flourishing of missile designs setting the stage for the exploration of space. The small American WAC Corporal rocket was evolved into the Aerobee, a much more powerful sounding rocket. Exploration of space began in earnest in 1947 with the flight of the first Aerobee, 46 of which had flown by the end of 1950.
