NASA and its partners have supported humans continuously living and working in space since November 2000. A truly global endeavor, the International Space Station has been visited by more than 280 people from 23 countries and a variety of international and commercial spacecraft. The unique microgravity laboratory has hosted more than 4,000 experiments from more than 5,000 researchers in more than 110 countries. The space station also is facilitating the growth of a commercial market in low Earth orbit for research, technology development, and crew and cargo transportation.
NASA created a dedicated logo to symbolize this historic achievement. The logo is visible in the cupola of the space station in this July 17, 2025, image. The central astronaut figure is representative of all those who have lived and worked aboard the station during the 25 years of continuous human presence. In the dark sky of space surrounding the astronaut are 15 stars, which symbolize the 15 partner nations that support the orbiting laboratory.
There is a visual representation of the space station toward the edge of the design, where humans have had a continuous presence for the past 25 years. The Earth represents the planet which the station orbits and that science conducted aboard the orbiting laboratory is for the benefit of all. Integrated into the border of the design is the number “25” to further represent the 25 years of human presence aboard the space station.
After 25 years of continuous human presence, the space station remains a training and proving ground for deep space missions, enabling NASA to focus on Artemis missions to the Moon and Mars.

自2000年11月以来，NASA及其国际合作伙伴便持续支持人类在太空中生活与工作，至今已有25年。国际空间站是一项真正的全球合作工程，已接待来自23个国家的280多位航天员，以及多种国际和商业飞船的访问。这个独特的微重力实验室已承载超过5,000位科研人员进行的4,000多项实验，涉及110多个国家。空间站也正推动近地轨道商业市场的发展，包括科研、技术开发、人员和货物运输等领域。
为纪念这一历史性成就，NASA专门设计了一个标志，用以象征这一里程碑。在2025年7月17日拍摄的这张照片中，该标志出现在国际空间站穹顶舷窗内。标志中央的人形航天员象征着过去25年间曾在空间站上生活与工作的所有航天员。在其周围的太空背景中点缀着15颗星星，代表着支持这座轨道实验室的15个国际合作国家。
在图案边缘可以看到空间站的形象，象征着人类在过去25年里对这座轨道平台的持续驻留。地球图案代表着空间站所绕行的家园，也象征着空间站上开展的科研是为了全人类的利益。标志的边框中巧妙地融合了数字“25”，进一步突出了人类持续在空间站存在的25周年这一主题。
经过25年持续不断的载人任务，国际空间站仍是深空探索任务的训练与验证平台，使NASA得以专注于“阿耳忒弥斯”登月计划及未来的火星探测任务。
