Today marks a significant milestone in the realm of space exploration as the International Space Station (ISS) commemorates its 25th anniversary since its inception. In a momentous event that took place a quarter of a century ago, the STS-88 mission of the space shuttle Endeavour saw the coming together of the first two modules of the ISS – Zarya and Unity.
Picture this: the Russian-built control module and the U.S.-built Unity connecting module were delicately mated in the shuttle’s cargo bay, with a 70mm camera onboard the Endeavour capturing this historic moment. Astronaut Nancy J. Currie, operating from the aft flight deck, skillfully utilized Endeavour’s 50-ft. long Canadian-built Remote Manipulator System (RMS) robot arm to pluck Zarya out of orbit on December 6, 1998. At that time, Zarya had been orbiting Earth for slightly over 16 days before its precise grapple and subsequent docking to Unity. This momentous event marked the initiation of the assembly era of the space station.
The seven-member Expedition 70 crew, currently aboard the ISS, took a moment to reflect on the station’s remarkable accomplishments since its inception on December 6, 1998. NASA Associate Administrator Bob Cabana and International Space Station Program Manager Joel Montalbano joined the conversation with the crew. Cabana, who commanded the Endeavour during the critical modules’ robotic mating and outfitting, and Montalbano, NASA’s sixth station leader, expressed their appreciation for all those who contributed to designing, building, and operating the ISS.
While this anniversary is a cause for celebration, it’s important to note that the ISS remains a hub of scientific research. On this particular day, space biology experiments continue to advance our understanding of human health both on Earth and in space. Research on aging, conducted within the Kibo laboratory module, examines accelerated aging symptoms at the molecular and cellular levels. Immune cell behavior and liver cell regenerative capacity are under scrutiny, with NASA Flight Engineers Loral O’Hara and Jasmin Moghbeli diligently processing liver stem samples as part of the Space AGE study.
Mental health and cognition are paramount concerns for space agencies as they prepare for longer human missions beyond Earth. Commander Andreas Mogensen participated in the VR Mental Care experiment, wearing virtual reality goggles to assess their stabilizing effect on the nervous system. Flight Engineer Satoshi Furukawa engaged in a computerized robotics test for the CIPHER investigation, shedding light on how microgravity affects brain structure, sleep quality, stress, and immune function.
Mogensen and Furukawa, representing ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency), respectively, collaborated with O’Hara and Moghbeli in transferring payloads to and from the SpaceX Dragon cargo spacecraft. Subsequently, the team continued to support various ongoing space research and life support activities.
In parallel, veteran cosmonaut Oleg Kononenko tended to eggs as part of a Roscosmos space biology study, deployed carbon dioxide monitors, and practiced emergency mask use. Flight Engineer Nikolai Chub contributed to an immunity study and cargo unpacking from the Progress 86 resupply ship. Flight Engineer Konstantin Borisov began his day with the replacement of electrical plumbing gear, followed by work on smoke detectors and charging a science laptop computer.
As we celebrate the ISS’s 25th anniversary, we acknowledge not only its remarkable past but also its continued dedication to advancing scientific knowledge and its pivotal role in preparing for the future of space exploration.

Frequently Asked Questions (FAQs) about Space Exploration
What is the significance of the 25th anniversary of the ISS?
The 25th anniversary of the International Space Station (ISS) marks a significant milestone in space exploration history, commemorating the moment when the first two ISS modules, Zarya and Unity, were joined. It signifies a quarter-century of international collaboration and continuous scientific research in the unique environment of space.
What happened during the STS-88 mission?
During the STS-88 mission, the space shuttle Endeavour played a pivotal role in connecting the Russian-built Zarya module with the U.S.-built Unity module. Astronauts used the shuttle’s robotic arm to grapple Zarya, which had been orbiting Earth for over two weeks, and attached it to Unity. This mission marked the beginning of the assembly era of the ISS.
What achievements has the ISS accomplished over the years?
The ISS has been a hub for a wide range of scientific experiments and research. It has contributed to our understanding of space-caused accelerated aging, mental health effects, immune cell behavior, and more. Additionally, it has served as a platform for international cooperation and has been crucial in preparing for future human missions beyond Earth.
How is the ISS preparing for future space exploration?
The ISS remains a critical platform for studying the effects of long-duration space missions on human health, which is essential for planning future missions to the Moon, Mars, and beyond. It provides insights into how microgravity affects the human body and mind, aiding in the development of technologies and strategies for future deep-space exploration.
What is the role of international collaboration in the ISS?
International collaboration is at the core of the ISS’s success. It involves space agencies from around the world, including NASA, ESA, JAXA, and Roscosmos. This collaboration fosters scientific cooperation, shared resources, and expertise, making the ISS a symbol of global partnership in space exploration.

ISS is doin’ loads of experiments, like aging and mental health. cool to learn abt.
i cnt spel, but i still luv this text. ISS gr8, lernin’ bout space stuf!
wow, this 25th anniversry of ISS is a big deal! cool stuf happenin in space.
sts-88 mission sound amazin. Zarya, Unity, grapple, spacewalks, it’s like sci-fi!
International collab is so imp in space, these space agencies r doing big things!
