The International Space Station (ISS) orbited our planet for more than 20 years. But like many other space laboratories, its operation will soon end. The end of the ISS will be uncommon compared to other probes out on orbit, as NASA decided to burn the station up in Earth's atmosphere.
After two decades, the ISS will be ending its service. Several astronomical studies had been completed with the help of the orbiting laboratory. Many scientists have also resided for a long time on the space station, pooling the greatest minds for achieving breakthroughs that the world had ever seen.
International Space Station Will End in 2030
IN SPACE - SEPTEMBER 17: In this handout photo provided by NASA, This view of the International Space Station over a blue and white Earth was taken shortly after the Space Shuttle Atlantis undocked from the orbital outpost at 7:50 a.m. CDT. The unlinking completed six days, two hours and two minutes of joint operations with the station crew. Atlantis left the station with a new, second pair of 240-foot solar wings, attached to a new 17.5-ton section of truss with batteries, electronics and a giant rotating joint. The new solar arrays eventually will double the station's onboard power when their electrical systems are brought online during the next shuttle flight, planned for launch in December.
According to NASA, the ISS construction required 42 separate launches. On Earth, the entire orbiting facility weighs 420,000 kilograms. Moreover, just a few meters are needed in order for the station to reach the scale of the massive football field.
Axiom director Christian Maender said in a Space report that they built the ISS with precise engineering techniques, allowing parts that have not seen each other to combine up in orbit. However, the greatness of the space station has a limit, and sometime in the future, it will stop working because it is aging.
The space agency is confident that the massive laboratory will keep working until 2030, even though the limit of ISS is until 2028 only.
Harvard astronomy expert Jonathan McDowell said that any cargo or ferry ship that visits the ISS has surplus propellant to conduct a rendezvous and an extra for reboost. If these items would stop replenishing the space station, the Earth's gravity and atmosphere will eventually pull down its entirety.
The decision to put down the ISS will be a joint mission among the participating international countries, including the United States, Japan, Canada, and Russia. Further plans will also be supported by the European Space Agency. Although NASA has announced that the space station will pursue missions until 2030, international partners have not signed the call just yet.

McDowell said that the details might seem abrupt for the participating agencies, and the decision was not fully detailed when the news was announced five years ago. According to the expert, decisions through deorbiting or rebuilding the ISS are not a possible outcome for the space station itself due to corresponding factors that will follow.
ISS Will Burn
NASA affirmed its decision over the future of ISS by passing an outline last January that describes the projected plans until 2030. It may have been common for many agencies, including NASA, to leave space crafts' afterlives unconsidered. But in terms of the space station's future, matters should be handled accordingly.
NASA and its partners will examine the steps to be taken to prevent the devastating event in 1979, where improper calculations and scheduling led the Skylab to be destroyed out on space and eventually fell down the planet's atmosphere.
With the help of engineers from Roscosmos, NASA submitted a paper in 2017 containing disposal options and expected catastrophes that may occur while pulling the plug of space stations. One approach was similar to the 2001 operation conducted over the Russian space station Mir.
The process will utilize the Russian Progress cargo vehicle, which will conduct a burn while docked at the station. In the latest 2022 report, three Progress ships will lower the ISS, along with the help of the Northrop Grumman's Cygnus.
The projection will achieve a precise prediction if the process is followed. It will suffice the required pull from the planet and allow the ISS to collide into the burning atmosphere and scatter its pieces across the southern Pacific Ocean.
