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.
Albert II, a rhesus monkey, became the first mammal in space aboard a U.S. V-2 rocket on June 14, 1949, and died on reentry due to a parachute failure. The first dogs in space were launched 22 July 1951 aboard a Soviet R-1V. "Tsygin" and "Dezik" reached a height of 100 km (62 mi) and safely parachuted back to Earth.
Japan's space agency, the Japan Aerospace Exploration Agency, is a major space player in Asia. While not maintaining a commercial launch service, Japan has deployed a module in the ISS and operates an uncrewed cargo spacecraft, the H-II Transfer Vehicle. [citation needed] JAXA has plans to launch a Mars fly-by probe.
This is a timeline of achievements in Soviet and United States spaceflight, spanning the Cold War era of nationalistic competition known as the Space Race. This list is limited to first achievements by the USSR and USA which were important during the Space Race in terms of public perception and/or technical innovation.
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).
This is a timeline of Solar System exploration ordering events in the exploration of the Solar System by date of spacecraft launch. It includes: It includes: All spacecraft that have left Earth orbit for the purposes of Solar System exploration (or were launched with that intention but failed), including lunar probes .
First Aerobee Hi launch, 21 April 1955. The Aerobee family of rockets expanded considerably this year, both in variety and capability. Most significant was the introduction of the Aerobee-Hi, doubling the altitude range of the Aerobee sounding rocket from 125 km (78 mi) to 220 km (140 mi) and increasing the payload carried from 68 kg (150 lb) to 91 kg (201 lb).
As the century ended, a permanent human presence in space was being founded with the ongoing construction of the International Space Station. In addition to human spaceflight, uncrewed space probes became a practical and relatively inexpensive form of exploration. The first orbiting space probe, Sputnik 1, was launched by the Soviet Union in ...
