The first space rendezvous was accomplished by Gemini 6A and Gemini 7 in 1965.. Records and firsts in spaceflight are broadly divided into crewed and uncrewed categories. Records involving animal spaceflight have also been noted in earlier experimental flights, typically to establish the feasibility of sending humans to outer space.
Human presence in outer space began with the first launches of artificial object in the mid 20th century, and has increased to the point where Earth is orbited by a vast number of artificial objects and the far reaches of the Solar System have been visited and explored by a range of space probes.
A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.

[49] [50] [51] The date of the Three sovereigns is fixed at 3000–2700 BC [52] and therefore dates the creation about ...
Twelve lunar months pass in 354 days, requiring a calendar to insert a leap month every two or three years in order to keep synchronized with the solar year's seasons (making it lunisolar). The earliest known descriptions of this coordination were recorded by the Babylonians in 6th or 7th centuries BC, over one thousand years later.
First human-piloted space flight (Alan Shepard). First human-crewed suborbital flight. USA Freedom 7: 19 May 1961: First planetary flyby (within 100,000 km of Venus – no data returned). USSR Venera 1: 6 August 1961: First crewed space flight lasting over twenty four hours by Gherman Titov, who is also the first to suffer from space sickness ...
The International Space Station has the longest period of continuous human presence in space, 2 November 2000 to present (24 years and 74 days). This record was previously held by Mir , from Soyuz TM-8 on 5 September 1989 to the Soyuz TM-29 on 28 August 1999, a span of 3,644 days (almost 10 years).
