NASA’s ISS will live on! Le operazioni per la stazione spaziale ora si estenderanno attraverso 2030 – ma il laboratorio orbitante crepato e con perdite durerà così a lungo??
NASA announced on Friday the Biden administration is extending operations of the International Space Station (ISS) attraverso 2030.
Congress has only approved funding for the massive orbiting laboratory until 2024, but the American space agency is now expecting additional money to power the station longer.
The move comes as NASA has offered hundreds of millions of dollars to private companies to build their own space stations that would take the place of the ISS.
Even though the ISS will live on, the aged ship itself may not last another six years longer than previously planned – it has formed cracks and leaks over the past few years.

President Ronald Regan announced the construction of the ISS during his January 25, 1984 State of the Union Address, noting NASA will have it completed in 10 anni.
Then on December 4, 1998, the first US component of the ship launched and two years later.
More pieces were sent into space over the following years and by 2000, the massive ship was ready for human occupants.
NASA’s Bill Shepard and Russia’s Yuri Gidzenko and Sergei Krikalev arrived at the station on November 2, 2000 and stayed for several months – and humans have lived on the ISS since.

The ISS became fully operational in May 2009 when it began hosting a six-person crew; this required two Soyuz lifeboats to be docked with the ISS at all times.
And the 356-foot-long station, was completed in 2011.
NASA Administrator Bill Nelson said in a dichiarazione di venerdì: ‘The International Space Station is a beacon of peaceful international scientific collaboration and for more than 20 years has returned enormous scientific, educativo, and technological developments to benefit humanity.
‘I’m pleased that the Biden-Harris Administration has committed to continuing station operations through 2030.’
NASA plans to continue working with its international partners in Europe (QUELLA, European Space Agency), Giappone (JAXA, Japan Aerospace Exploration Agency), Canada (CSA, Canadian Space Agency), and Russia (State Space Corporation Roscosmos) ‘to enable continuation of the groundbreaking research being conducted in this unique orbiting laboratory through the rest of this decade.’
It is not clear how Friday’s announcement will impact NASA’s offer to private companies to build their own space stations.
All'inizio di quest'anno, NASA unveiled the Commercial LEO (low-Earth orbit) Destinations project to help private companies build their own space station, with NASA being one of ‘many’ clienti.

It was then announced earlier this month that NASA awarded three companies with contracts to build privately-owned and operated space stations in low Earth orbit.
The list includes Jeff Bezos’ Blue Origin, Northrop Grumman and Nanoracks, all of which are receiving a combined $415.6 million under NASA’s Commercial LEO Destinations (CLD) progetto, the agency announced on Thursday.
Nanoracks won the largest individual award with an $160 milioni, while Blue Origin and Northrop Grumman received $130 million and $125.6 milioni.
The ISS, però, was only meant to last for 15 years and is starting to show signs of aging.
Nel mese di settembre, a former NASA astronaut Shepherd, who was one of the first people on the ISS, revealed cracks were spotted in the Russian Zarya module in August.
Nel mese di settembre, a former NASA astronaut William Shepherd (nella foto), who was one of the first people on the ISS, revealed cracks were spotted in the Russian Zarya module in August. Shepherd reiterated claims by Roscosmos, the Russian space agency, that it was ‘becoming a serious issue’
NASA says the cracks on the $150 miliardi (£109 billion) laboratory did not pose any danger to astronauts ‘at this time’, and no new leaks had been identified.
Shepherd told a House of Representatives committee hearing on Tuesday that NASA and Russian engineers ‘don’t exactly understand why the cracks are appearing now.’
Shepherd reiterated claims by Roscosmos, the Russian space agency, that it was ‘becoming a serious issue,’ adding that it needs to be resolved before Congress clears the ISS for operational use beyond the current 2024 funding deadline.
Vladimir Solovyov, chief engineer of Russian rocket and space corporation Energia, said in August a number of ‘superficial fissures’ had been found on Zarya.
This is module is also known as the ‘Functional Cargo Block’ and Solovyov said the fissures had been uncovered in a ‘number of places’.
‘This is bad and suggests that the fissures will begin to spread over time,’ Solovyov told Russian state-owned news agency RIA.
He added that a significant portion of the equipment on the ISS is ageing.
NASA vehemently denied claims from Russia that there were ‘bad’ cracks on the module, saying there were no issues ‘impacting crew or normal operations.’
agosto 2018 saw astronauts rush to fix a hole (nella foto) which had appeared in the outer wall of the Soyuz capsule on the orbiting laboratory. Its origins were, and still are, a mystery despite rife speculation
The space agency told DailyMail.com that ‘no new potential leak sites have been identified’ by astronauts or ground crew.
‘We are in regular coordination for station operations with all our international partners, including Roscosmos.’
Shepherd, who has flown to orbit four times, said the cracks are small, like scratches on the surface of the aluminium plate – ‘something like half a dozen of them’.
Last year alone a toilet broke, temperatures increased without explanation or warning and an oxygen-supply system broke down.
però, the station is full of redundancies, including ‘escape capsules’ that can take all of the between six and 10 crew members back to Earth in an emergency.
Nel mese di settembre 2019 another module, Zvezda, also on the Russian side, started leaking air – there was no immediate danger, but it was eventually located and repaired.
Solovyov previously said: ‘There are already a number of elements that have been seriously damaged and are out of service. Many of them are not replaceable. Dopo 2025, we predict an avalanche-like failure of numerous elements onboard the ISS.’
In a statement to the House, Shepherd said: ‘Since last fall, ISS has experienced moderate internal air leakage to space. Leaks have been traced to the interior of the transfer tunnel at the rear of the Russian Service Module.
‘Leak sources are small surface cracks in the tunnel’s aluminum hull. The crew has sealed leak sites, and the leakage rates have reduced.
‘Engineers and technicians in Russia and the U.S. work together to understand and resolve this issue; but the root cause of the cracking, their failure modes, and impacts on ISS safety and future operations have not been adequately determined.
‘I don’t think the station’s in any immediate danger. But before we clear the station for another so many years of operational use, we should better understand this.’
Infine, when the core structure becomes beyond repair, the ISS will be retired and sent to burn up in the Earth’s atmosphere, after which point NASA says it has no plans to fund or operate its own station in Earth orbit.
SPIEGATO: IL $100 BILLION INTERNATIONAL SPACE STATION SITS 250 MILES ABOVE THE EARTH
The International Space Station (ISS) is a $100 miliardi (£80 billion) science and engineering laboratory that orbits 250 miglia (400 km) above Earth.
It has been permanently staffed by rotating crews of astronauts and cosmonauts since November 2000.
Crews have come mainly from the US and Russia, but the Japanese space agency JAXA and European space agency ESA have also sent astronauts.
The International Space Station has been continuously occupied for more than 20 years and has been expended with multiple new modules added and upgrades to systems
Research conducted aboard the ISS often requires one or more of the unusual conditions present in low Earth orbit, such as low-gravity or oxygen.
ISS studies have investigated human research, space medicine, life sciences, physical sciences, astronomy and meteorology.
The US space agency, NASA, spends about $3 miliardi (£2.4 billion) a year on the space station program, with the remaining funding coming from international partners, including Europe, Russia and Japan.
Finora 244 individuals from 19 countries have visited the station, and among them eight private citizens who spent up to $50 million for their visit.
There is an ongoing debate about the future of the station beyond 2025, when it is thought some of the original structure will reach ‘end of life’.
Russia, a major partner in the station, plans to launch its own orbital platform around then, with Axiom Space, a private firm, planning to send its own modules for purely commercial use to the station at the same time.
NASA, QUELLA, JAXA and the Canadian Space Agency (CSA) are working together to build a space station in orbit around the moon, and Russia and China are working on a similar project, that would also include a base on the surface.
