In 2024, the clock will run out on the international space station. Maybe that is the arbitrary deadline that Congress imposed back in 2014, at which point they will have to decide whether or not to keep funding the international space station.
According to The Verge, It costs NASA between $3 and $4 billion to operate its share of the international space station each year. Moreover, as NASA is more determined to make a change for the future, which includes sending human beings into space and onto Mars.
However, the congress, specifically the house committee on science, space, and technology decides how much money NASA will get yearly. It is reported that the politicians are holding proceedings to discuss what could be the possible fate of the International Space Station in seven years time.
Furthermore, the International Space Station is said to have had significant updates since the assembly began in the year 1998, but it was only in the last few years that the final modules have gone up. Nevertheless, seven years might sound like ages, but it is not a very long time to make an important decision.
Although It is speculated that NASA is not going to get enough allocation to allow the congress to achieve all the projects, nonetheless, this funding question will push the agency down one route or the other. The decision is left to the congress, specifically, the house committee on science, space, and technology. It's time to make a move reported Popular Science.
Meanwhile, this is not to say that the international space station will not be funded for a very long time, but with the recent increase in the number of private space travel companies like SpaceX and Virgin Galactic, the international space station may be taken over by these industries some day, especially if other companies are interested in developing the products for use in outer space.
