For twenty-four hours an afternoon, seven days per week since November 2000, NASA and its world companions have sustained a continual human presence in low-Earth orbit, together with a minimum of one American – a streak that can quickly achieve 25 years.
When considered within the historical past of spaceflight, the World Area Station is possibly one in every of humanity’s maximum superb accomplishments, a shining instance of cooperation in area a number of the United States, Europe, Canada, Japan and Russia. However all excellent issues should come to an finish.

In 2030, the World Area Station will likely be deorbited: pushed right into a far flung space of the Pacific Ocean.
I’m an aerospace engineer who has helped construct a spread of {hardware} and experiments for the ISS. As a member of the spaceflight neighborhood for over 30 years and a 17-year member of the NASA neighborhood, it’ll be laborious for me to peer the ISS come to an finish.
Because the first items of the World Area Station have been introduced in 1998, the station has been house to important analysis accomplishments throughout domain names that come with fabrics science, biotechnology, astronomy and astrophysics, Earth science, combustion and extra.
Astronauts appearing analysis throughout the area station and payload experiments hooked up to the station’s external have generated many publications in peer-reviewed science journals. A few of them have complex our working out of thunderstorms, ended in enhancements within the crystallization processes of key cancer-fighting medicine, detailed develop synthetic retinas in area, explored the processing of ultrapure optical fibers and defined collection DNA in orbit.
The ISS’s microgravity surroundings has made it the optimum surroundings for numerous medical analysis tasks.

In overall, greater than 4,000 experiments were performed aboard the ISS, leading to greater than 4,400 analysis publications devoted to advancing and making improvements to existence on Earth and serving to forge a trail for long term area exploration actions.
The ISS has confirmed the worth of engaging in analysis within the distinctive surroundings of spaceflight – which has very low gravity, a vacuum, excessive temperature cycles and radiation – to advance scientists’ working out of quite a lot of necessary bodily, chemical and organic processes.
Holding a presence in orbit
However within the wake of the station’s retirement, NASA and its world companions aren’t forsaking their outpost in low-Earth orbit. As an alternative, they’re searching for choices to proceed to benefit from low Earth orbit’s promise as a novel analysis laboratory and to increase the continual, 25-year human presence some 250 miles (402 kilometers) above the Earth’s floor.
In December 2021, NASA introduced 3 awards to assist broaden privately owned, commercially operated area stations in low-Earth orbit.
For years, NASA has effectively despatched provides to the World Area Station the use of business companions, and the company just lately started an identical trade preparations with SpaceX and Boeing for transporting staff aboard the Dragon and Starliner spacecraft, respectively.

In keeping with the good fortune of those techniques, NASA invested greater than US$400 million to stimulate the improvement of business area stations and confidently release and turn on them ahead of the ISS is decommissioned.
First light of business area stations
In September 2025, NASA issued a draft announcement for Segment 2 partnership proposals for business area stations. Firms which might be decided on will obtain investment to fortify vital design critiques and exhibit stations with 4 folks in orbit for no less than 30 days.
NASA will then transfer ahead with formal design acceptance and certification to make sure that those stations meet NASA’s stringent protection necessities. The result will permit NASA to buy missions and different services and products aboard those stations on a business foundation – very similar to how NASA will get shipment and staff to the ISS as of late.
Which of those groups will likely be a success, and on what timescale, continues to be observed.
Whilst those stations are being constructed, Chinese language astronauts will proceed to reside and paintings aboard their Tiangong area station, a three-person, completely crewed facility orbiting roughly 250 miles (402 km) above the Earth’s floor. As a result, if the ISS’s occupied streak involves an finish, China and Tiangong will take over because the longest frequently inhabited area station in operation: It’s been occupied for about 4 years and counting.

Within the interim, benefit from the view
It’ll be a number of years ahead of any of those new business area stations circle the Earth at round 17,500 miles according to hour (28,000 kilometers according to hour) and several other years ahead of the ISS is deorbited in 2030.
So whilst you have a possibility, have a look up and benefit from the view. On maximum nights when the ISS flies over, it’s merely magnificent: a super blue-white level of sunshine, most often the brightest object within the sky, silently executing a swish arc around the sky.
Our ancestors may just infrequently have imagined that someday, one of the most brightest gadgets within the evening sky would were conceived via the human thoughts and constructed via human arms.
