When viewed in the history of spaceflight, the International Space Station is perhaps one of humanity\u2019s most amazing accomplishments, a shining example of cooperation in space<\/a>among the United States, Europe, Canada, Japan and Russia. But all good things must come to an end.<\/p>\n In 2030, the International Space Station will be deorbited<\/a>: driven into a remote area of the Pacific Ocean.<\/p>\n I\u2019m an aerospace engineer<\/a> who has helped build a range of hardware and experiments for the ISS. As a member of the spaceflight community for over 30 years and a 17-year member of the NASA community, it will be hard for me to see the ISS come to an end.<\/p>\n Since the first pieces of the International Space Station were launched in 1998, the station has been home to significant research accomplishments<\/a> across domains that include materials science, biotechnology, astronomy and astrophysics, Earth science, combustion and more.<\/p>\n Astronauts performing research inside the space station and payload experiments attached to the station\u2019s exterior have generated many publications in peer-reviewed science journals. Some of them have advanced our understanding of thunderstorms<\/a>, led to improvements in the crystallization processes<\/a> of key cancer-fighting drugs, detailed how to grow artificial retinas<\/a> in space, explored the processing of ultrapure optical fibers<\/a> and explained how to sequence DNA in orbit<\/a>.<\/p>\n The ISS\u2019s microgravity environment has made it the optimal environment for a variety of scientific research projects. (Photo by NASA, CC BY)<\/p>\n In total, more than 4,000 experiments have been conducted aboard the ISS, resulting in more than 4,400 research publications<\/a> dedicated to advancing and improving life on Earth and helping forge a path for future space exploration activities.<\/p>\n The ISS has proven the value of conducting research in the unique environment of spaceflight \u2013 which has very low gravity, a vacuum, extreme temperature cycles and radiation \u2013 to advance scientists\u2019 understanding of a wide range of important physical, chemical and biological processes.<\/p>\n Keeping a presence in orbit<\/p>\n But in the wake of the station\u2019s retirement, NASA and its international partners are not abandoning their outpost in low-Earth orbit. Instead, they are looking for alternatives to continue to take advantage of low Earth orbit\u2019s promise as a unique research laboratory and to extend the continuous, 25-year human presence some 250 miles (402 kilometers) above the Earth\u2019s surface.<\/p>\n In December 2021, NASA announced three awards<\/a> to help develop privately owned, commercially operated space stations <\/a>in low-Earth orbit.<\/p>\n For years, NASA has successfully sent supplies to the International Space Station using commercial partners<\/a>, and the agency recently began similar business arrangements with SpaceX and Boeing for transporting crew aboard the Dragon<\/a> and Starliner spacecraft<\/a>, respectively.<\/p>\n Based on the success of these programs, NASA invested more than US$400 million to stimulate the development<\/a> of commercial space stations and hopefully launch and activate them before the ISS is decommissioned.<\/p>\n Dawn of commercial space stations<\/p>\n In September 2025, NASA issued a draft announcement for Phase 2 partnership proposals<\/a> for commercial space stations. Companies that are selected will receive funding to support critical design reviews and demonstrate stations with four people in orbit for at least 30 days.<\/p>\n NASA will then move forward with formal design acceptance and certification to ensure that these stations meet NASA\u2019s stringent safety requirements. The outcome will allow NASA to purchase missions and other services aboard these stations on a commercial basis \u2013 similar to how NASA gets cargo and crew to the ISS today.<\/p>\n Which of these teams will be successful, and on what timescale, remains to be seen.<\/p>\n While these stations are being built, Chinese astronauts will continue to live and work aboard their Tiangong space station<\/a>, a three-person, permanently crewed facility orbiting approximately 250 miles (402 km) above the Earth\u2019s surface. Consequently, if the ISS\u2019s occupied streak comes to an end, China and Tiangong will take over as the longest continually inhabited space station in operation: It\u2019s been occupied for approximately four years and counting.<\/p>\n In the meantime, enjoy the view<\/p>\n It will be several years before any of these new commercial space stations circle the Earth<\/a> at around 17,500 miles per hour<\/a> (28,000 kilometers per hour) and several years before the ISS is deorbited in 2030.<\/p>\n So while you have a chance, take a look up<\/a> and enjoy the view. On most nights when the ISS flies over, it is simply magnificent: a brilliant blue-white point of light, usually the brightest object in the sky, silently executing a graceful arc across the sky.<\/p>\n Our ancestors could hardly have imagined that one day, one of the brightest objects in the night sky would have been conceived by the human mind and built by human hands.<\/p>\n This article is republished from The Conversation<\/a> under a Creative Commons license.
