Congress is questioning whether it's feasible to 'store' the International Space Station (ISS) in a safe orbital harbor after its operational life is over. The proposal, submitted by Rep. George Whitesides (D-Calif.), aims to direct NASA to reassess its plans for the ISS after 2030.
Whitesides believes that storing the station could provide valuable scientific insights and potentially open up new opportunities for future generations. This proposition comes as part of a larger bill aimed at reauthorizing NASA's budget and outlining policy guidelines for the agency.
NASA has currently planned to deorbit the space station in 2031 over the Pacific Ocean, after which debris that survives the scorching reentry will fall into a remote part of the sea. The agency considers this method safer than any other alternative due to concerns over the risk of fatalities and property damage from debris reaching land.
However, according to NASA analysis released last year, deorbiting the ISS could result in massive propellant consumption โ around 10 tons (9 metric tons) for a decrease of just 127 mph. An alternative approach involves boosting the station's orbit to somewhere between 400 and 420 miles (640 to 680 kilometers), but this too has its challenges.
The development of new, high-altitude vehicles capable of delivering significant cargo to these orbits is currently under development, yet significant engineering hurdles remain. There is also a risk that the space station could collide with other debris in space at around 500 miles above Earth's surface.
Some lawmakers, including Rep. George Whitesides and his cosponsor Rep. Nick Begich (R-Alaska), are urging caution on deorbiting the ISS without first conducting further study on this option. They believe it is essential to understand the technical feasibility of preserving the complex in orbit for future generations before making a decision.
In contrast, SpaceX has been awarded nearly $1 billion to develop an enhanced version of its Dragon spacecraft to deorbit the station and re-enter Earth's atmosphere safely.
