Nasa is closely monitoring four cracks and 50 other "areas of concern" on the ISS. While astronauts can cover the cracks with patches or sealant, these are largely temporary solutions.If the leaks get significantly worse, and start to present a danger, astronauts can close off the tunnel completely. <nbtemplate data-id="AdPlaceholder" data-content="JTdCJTdE"></nbtemplate>Although that will mean losing a valuable docking port used by Progress and Soyuz spacecraft."We have conveyed the seriousness of the leaks multiple times, including when I was in Russia earlier this year," Nasa's associate administrator, Jim Frees, told the Washington Post. For now, Nasa has agreed with Roscosmos to shut the hatch to the Russian module in the evenings.Nasa astronauts will also remain on the US side of the station to be close to their escape vehicles, should an evacuation be necessary. <h2>The race to replace the ISS</h2><figure><img src="https://img.particlenews.com/image.php?type=thumbnail_580x000&amp;url=1VK5ka_0wPYFGmn00" alt="https://img.particlenews.com/image.php?url=1VK5ka_0wPYFGmn00" width="620" height="413" ></figure><nbtemplate data-id="AdPlaceholder" data-content="JTdCJTdE"></nbtemplate>The ISS has been orbiting Earth since 1998 - but nothing within Earth's orbit can stay in space forever.The station will continue working until 2030, before plunging into the Pacific Ocean in early 2031, according to Nasa.In December 2021, the US space agency announced it was awarding a total of $415million (£326million) to three different companies — Blue Origin, Nanoracks (plus Voyager Space) and Northrop Grumman — to help cement their commercial space station concepts.Nasa also has separate agreements with Vast and Texas-based Axiom Space, which is working on its own private outpost <a href="https://www.the-sun.com/tech/7637491/nasa-new-spacesuit-astronauts-wear-to-moon/">as well as a new series of spacesuits.</a>Northrop Grumman had initially had its own plans for a space station when Nasa funded it.However, the company dropped its idea in October last year, to assist Voyager Space with <a href="https://www.the-sun.com/tech/10260100/elon-musk-spacex-starship-starlab-international-space-station-replace/">Starlab</a> instead. <nbtemplate data-id="AdPlaceholder" data-content="JTdCJTdE"></nbtemplate>California-headquartered Vast has put forward its own ISS-successor, dubbed <a href="https://www.the-sun.com/tech/12665736/vast-mega-space-station-haven-2-replace-iss/">the Haven-2</a>, which it says could be fully operational in orbit by 2028.<h2>Space debris</h2>Space debris is increasingly a threat to the ISS, which is roughly the size of a football field, and therefore an easy target.The outpost occasionally has to move its orbit to dodge larger pieces of space junk. In June, astronauts aboard the <a href="https://www.the-sun.com/tech/11753956/iss-international-space-station-astronauts-russian-satellite-debris/">ISS were forced to take cover</a> when a defunct Russian shattered into 200 metal pieces in orbit. However, this is not always possible to dodge debris, particularly with the smaller pieces.Shards of metal no bigger than a fleck of paint can do the ISS enough damage that astronauts have to spend weeks repairing it. <nbtemplate data-id="AdPlaceholder" data-content="JTdCJTdE"></nbtemplate></div></body>
