  • The Indian Space Research Organization, or ISRO, announced in June that it plans to launch

  • its own space station by 2030.

  • Along with Russia, the United States, and China, this would make India the fourth country

  • to launch a space station that is solely their own.

  • It’s an ambitious goal, especially for a country that has yet to send a human being

  • into space.

  • They haven’t released any concrete plans on how theyll build their station or what

  • it will look like.

  • So, what challenges did other nations face when they put their first space stations into

  • orbit?

  • The Soviet Union launched the first space station ever, Salyut 1, in 1971.

  • It was in orbit for 175 days and occupied for 23 before the crew departed.

  • Tragically, their return capsule depressurized, and all three crew members perished.

  • The U.S.S.R.’s next two attempts, Salyut 2 and Kosmos 557, each were crippled after

  • achieving orbit and neither were ever occupied.

  • The U.S.’s first space station, Skylab launched three days after Kosmos 557 in 1973, and as

  • you might have guessed, it was damaged during launch.

  • Still, some improvised repairs made Skylab habitable, and it was occupied by three crews

  • before reentering the atmosphere and breaking up in 1979.

  • Ground controllers attempted to have the debris land in the Indian Ocean, but some of it landed

  • in western Australia.

  • While no one was hurt, the Shire of Esperance did fine NASA $400 for littering.

  • Clearly, a crewed space station is a daunting task to get right on your first try.

  • The next country to launch an independent space station was China in 2011.

  • The school-bus sized Tiangong-1 wasn’t meant to be a permanent facility, but a platform

  • to test and master the technologies needed for more ambitious modular station in the future.

  • Two crewed missions visited the station in 2012 and 2013, and at that point its mission

  • was essentially done.

  • But just in case something went wrong with its successor, Tiangong-2, the Chinese decided

  • to put the station into hibernation rather than deorbit it.

  • When they attempted to wake it up again in 2016, they found the station had lost power.

  • That meant it was uncontrollable, and where it landed, was up to gravity.

  • Fortunately, Tiangong-1 reentered harmlessly over the southern Pacific in April of 2018.

  • Chinese officials bristle at the notion the reentry was uncontrolled, but honestly it

  • just means they join the club of nations whose first space stations weren’t 100% flawless missions.

  • So far, were 0 for 3.

  • But we have also had stunning successes with space stations too.

  • The International Space Station has been hosting astronauts and doing science since the year

  • 2000.

  • But the ISS is really something special and it’s not a project that any one country

  • can undertake.

  • It took the cooperation and funding of space agencies from Russia, the United States, Europe,

  • Japan, and Canada to assemble it in orbit over a decade.

  • It took 5 Russian rocket launches plus more than 35 space shuttle missions to haul all

  • its pieces into orbit.

  • Today, NASA’s budget for their share of the operation, maintenance, and research costs

  • total 1.45 billion dollars each year, which as it happens is reportedly the entire annual

  • budget of ISRO.

  • Clearly a space station that huge is out of the question for any one country.

  • Which brings us back to India.

  • Will they be the only nation to have a totally successful space station on their first go?

  • Before they even attempt that, they have a lot of work ahead of them.

  • They have yet to launch a human into space with a rocket of their own, though theyre

  • inching closer.

  • ISRO is reportedly on track to launch an uncrewed Gaganyaan spacecraft by December of 2020.

  • After a second uncrewed mission, their goal is to launch three astronauts by December

  • 2021.

  • Once in low-Earth orbit, the three person crew will remain aloft for 5-7 days before

  • returning safely to Earth.

  • I make it sound so simple, but remember that space flight is never routine.

  • There's always a risk, especially when a space program is just getting its wings.

  • And ISRO has been ambitious and achieved a lot with the resources it has, but theyre

  • not immune to failure.

  • Their first attempt at a moon lander crashed into the moon’s surface earlier this year.

  • So when it comes to their first crewed missions, weve got our fingers and toes crossed that

  • all goes well.

  • If the Gaganyaan missions are successful, then ISRO can seriously start to consider

  • building a permanent home above the Earth.

  • If you want to more about what ISRO has been up to, check out our video on their Chandrayaan-2

  • mission to the moon that we was made before it launched.
