After more than 30 years as the world’s cosmic crash pad, NASA has said that the International Space Station will be “deorbited” in January 2031.

The 109m wide galactic* vessel will likely come down in a fiery blaze as it passes through Earth’s atmosphere, hurtling down the 365km to Earth’s surface at a rate of nearly 27,360km per hour.

But don’t worry – it certainly won’t come down anywhere near a city or town. Rather, it will meet its watery end in the South Pacific.

The space agency’s recent budget estimates report showed plans to decommission* the ISS by 2030 before it splashes down at Point Nemo, about 2700km away from land on all sides.

Sometimes called the “oceanic pole of inaccessibility” or the “South Pacific Uninhabited* Area,” the marine zone has for decades been used as the final resting place for old space equipment, such as satellites and rocket debris.

NASA called the waters of Point Nemo “pretty much the farthest place from any human civilisation you can find.”

As far as a replacement down the road, there won’t be any new and improved ISS; rather, NASA intends to work with commercial spaceflight ventures to board their astronauts during long-haul stints in orbit — while saving an estimated $1.3 billion US (the equivalent of over $1.8 billion in AUD) in just the first year after vacating* the ISS.

Robyn Gatens, the director of the International Space Station at NASA headquarters, said the organisation’s goal is to “lay the groundwork* for a commercial future in low-Earth orbit.”

Phil McAlister, the director of commercial space at NASA headquarters, also said in a statement, “We look forward to sharing our lessons learned and operations experience with the private sector to help them develop safe, reliable and cost-effective destinations in space.”

The agency stated that money saved on space station maintenance may “be applied to NASA’s deep space exploration initiatives, allowing the agency to explore further and faster into deep space.”

media_cameraThe ISS has been the headquarters of human activity in space for more than two decades and has taken delivery of some unusual items in that time, including Australian wattle seeds carried by this Space X ship.

Last year, a Russian space official warned of small cracks in the ISS structure that engineers fear may become too big — and expensive — to repair to maintain the structure into the future. ISS was “examining the recent technical issues aboard the Russian segment,” NASA said in its report.

The space station, about the size of a football field, has continuously housed astronauts since the year 2000, though it was originally intended to operate for only 15 years.

CLASSROOM ACTIVITIES
1. “Holiday in Space” brochure
One of NASA’s goals is to help support private providers to develop safe, cost-effective and reliable trips to space for leisure purposes, rather than just astronauts being sent into space for scientific research.

Create a travel brochure marketed towards a “Holiday in Space”. To be appealing to the everyday person it would need to be safe, not hugely expensive and not too long a time frame (just like planning a normal holiday!). Your brochure should outline the destination, method of travel, cost, included activities and meals and so forth.

Share your brochure with the class and vote which holiday looks the most appealing to you.

2. Extension
What might you be doing in January 2031 when it’s planned for the International Space Station to come back down to earth? Would you be interested in watching this event from afar?

In the nine years between now and then, what other space exploration may have taken place, do you think?
