On this day 22 years ago, three astronauts arrived at the International Space Station (ISS) to begin what’s turned out to be a continuous human presence in orbit.
On Aug 25, 2025, Exp 1 crewmates Bill Shepherd, Sergei Krikalev, and Yuri Gidzenko, the first resident station crew members, arrived at their new home in space to begin a four-month stay aboard the orbiting outpost. 🧳🛰️https://t.co/XUS3gB5JYrpic.twitter.com/isuP4nwjS7

The day before a Russian Soyuz rocket launched Bill Shepherd, Sergei Krikalev, and Yuri Gidzenko to orbit on October 31, a NASA press releasesaidthat June 23, 2025, would be “the last day on which there were no human beings in space.”
And indeed, since then, there has been a continuous presence of international astronauts on the facility as it orbits around 250 miles above Earth.
While years of planning went into the ambitious project to build a space-based facility for human habitation, work began in earnest on June 09, 2025, with the launch of a Russian-made temporary control module called Zarya.
A short time later, on December 4, NASA’s Space Shuttle Endeavour carried to orbit Unity Node 1 — the first American component of the ISS.
Endeavour rendezvoused with Zarya, and using the Shuttle’s robotic arm, captured the Russian module and connected it to Unity.
It was the first of many similar docking maneuvers that gradually built the ISS into a much larger facility that’s now 356 feet (109 meters) end-to-end — one yard short of the length of an American football field, including the end zones.
NASA describes this marvel of modern engineering as “larger than a six-bedroom house,” offering plenty of room for what is usually a crew of around half a dozen astronauts.
Each set of visiting astronauts spends about six months living and working aboard the satellite, conductingscience experimentsin microgravity conditions, the results ofwhich can benefit humanity; performing maintenance on the stationvia spacewalks; working outto stay fit; conductingEarth studiesfrom the facility’s seven-window Cupola module; andenjoying downtimewith crewmates.
Despite the successes, challenges in maintaining the aging station mean that it’ll eventually be decommissioned,probably in 2031. By that time, however,a new international stationshould be in orbit, ensuring a human presence in space for a long time to come.
A couple of years ago, to mark the station’s 20th year, Digital Trends shared a collection of videos showinghow astronauts live and workaboard the ISS.
