# Timeline of the Space Race

"none" is preferred when the title is sufficiently descriptive; see [[WP:SDNONE]]
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. This excludes first uses of specific on-board equipment and new scientific discoveries, or achievements by other countries.
