Make space great again: Why the International Space Station still matters
As one of the biggest manmade structures in the sky and at a cost of over $100b, it's the place where the space age dream is still alive.
Soaring through the deep sky, a marvel of human engineering orbits around the planet 16 times a day. For the last two decades, the International Space Station (ISS) has housed hundreds of astronauts some 250 miles high. This multinational construction project has given us a permanent presence in space. It has been continuously occupied since November 2nd, 2000. The main modules of construction were completed between 1998 and 2011. The station has since evolved as a roving temporary home for nomadic astronauts experimenting and living in zero gravity.
As of January 2018, 230 astronauts have visited the International Space Station. The ISS has a heavy American and Russian presence. Over 15 nations have contributed to funding throughout the years. Alongside NASA, Roscosmos from Russia and the European Space Agency (ESA) are also major partners funding most of the space station.
With current plans in place, it’s expected that the space station will remain in operation until 2024 with a possible extension to 2028. There have also been a few calls for the station to be privatized as well. Time will tell what becomes of the space station. ISS stands at the forefront of what’s possible on the periphery of space.
Largest manmade structure to grace the skies
Spanning the area the size of a football field, the space station weighs 391,000 kilograms – not including visiting space shuttles. The entire complex has more living space than a suburban five bedroom home. It has two bathrooms, workout facilities and a circular bay window for stunning views of the earth. Many astronauts have compared the living conditions to the inside of a Boeing jumbo jet.
The ISS can be seen with the naked eye as it zooms around the world at 17,500 miles per hour. It looks like an unblinking white light, but with a good telescope, you can see it in greater detail. Its flight path is available online, so you can track it to see when it makes a trek above your backyard.
The International Space Station is an orbiting powerhouse of scientific experimentation with over $100 billion worth of pressurized modules, solar arrays, and cutting-edge tools housed in the structure. It was built piece-by-piece as different segments were put into orbit and then assembled carefully by spacewalking astronauts and controlled robotics. Most of the heavier pieces were brought up during the time of the United States’ space shuttle program. Other individual modules were launched using single-use rockets. The many different modules that make up the ISS include: living quarters, laboratories, structural trusses & solar panels for power.
The first two modules launched was the Russian Zarya and the NASA Unity/Node 1 modules. Spacewalking astronauts helped connect these two stations together. Throughout the years the following modules were added to create the superstructure that orbits the Earth today.
Truss, airlocks and solar panels. Launched in stages throughout ISS lifetime.
Zvezda (Russia; launched in 2000)
Destiny Laboratory Module (NASA; launched 2001)
Canadarm2 robotic arm (CSA; launched 2001).
Harmony/Node 2 (NASA; launched 2007)
Columbus orbital facility (ESA; launched 2008)
Dextre robotic hand (CSA; launched 2008)
Japanese Experiment Module or Kibo (launched between 2008-09)
Cupola window and Tranquility/Node 3 (launched 2010)
Leonardo Permanent Multipurpose Module (ESA launched permanently in 2011)
Bigelow Expandable Activity Module (private module launched in 2016)
The place where the space age dream is still alive
Shuttling astronauts to and fro, hasn’t garnered much fanfare from the populace. Aside from a few novel experiments like Scott Kelly’s recent year-long session in space, ISS expeditions have gotten minimal coverage. The ISS has produced an incredible amount of scientific output and many discoveries that will pave the way for the future of space exploration and human colonization.
NASA’s research page lists thousands of different experiments conducted over the past twenty years. Big Think in a conversation with biochemist and astronaut, Peggy Whitson, whose visited and stayed at the ISS three times had the following to say about some of her experiments in orbit.
“Everything, from super-conductor crystals, I grew soybeans, did colloidal suspension of iron, different kinds of gas/liquid flow through columns, combustion experiments. So, all kinds of things.”
All of these experiments were distinguished by the fact that they lacked Earth’s gravity, which is a huge variable to get rid of. As we have dreams of expanding and living in space, knowing the effects or lack thereof of gravity is going to be one of the defining aspects of our space future. Some of Whitson’s work in space has led her to help develop a drug that fights cancer cells, by studying them in zero gravity.
Other upcoming experiments like bringing the Cold Atom Lab designed by NASA’s Jet Propulsion Laboratory (JPL), are going to help us ask questions about the strange physics of absolute zero.
By the time ISS makes its return back to earth in the late 2020s or is repurposed, it will have set the foundation for the future of space stations and other space-faring adventures.
A stepping stone to the greater cosmic neighborhood
Space is unbelievingly big and filled with strange phenomena. That being said, there’s a lot of places closer to home we can start to inhabit and expand into. There are a lot of ideas being thrown around about what’s next after the ISS. For example, the Russian space agency has plans to add a five-star luxury suite to the ISS in an early bid to start up some space commercialization. The module is planned to launch in 2021.
The Deep Space Gateway is the next step for NASA and the international space community as they come up with a full-fledged replacement for the ISS. It will be much smaller but may be heading out further than even the Apollo missions as it orbits around the moon. The hope is that it will serve as a central hub for future Mars missions.
The International Space Station is a testament to the globalized world’s ability to cooperate and connect in the future of space. This amazing structure is just the beginning of a possible new golden age of space.

Astronomers find these five chapters to be a handy way of conceiving the universe's incredibly long lifespan.
- We're in the middle, or thereabouts, of the universe's Stelliferous era.
- If you think there's a lot going on out there now, the first era's drama makes things these days look pretty calm.
- Scientists attempt to understand the past and present by bringing together the last couple of centuries' major schools of thought.
The 5 eras of the universe<p>There are many ways to consider and discuss the past, present, and future of the universe, but one in particular has caught the fancy of many astronomers. First published in 1999 in their book <a href="https://amzn.to/2wFQLiL" target="_blank"><em>The Five Ages of the Universe: Inside the Physics of Eternity</em></a>, <a href="https://en.wikipedia.org/wiki/Fred_Adams" target="_blank">Fred Adams</a> and <a href="https://en.wikipedia.org/wiki/Gregory_P._Laughlin" target="_blank">Gregory Laughlin</a> divided the universe's life story into five eras:</p><ul><li>Primordial era</li><li>Stellferous era</li><li>Degenerate era</li><li>Black Hole Era</li><li>Dark era</li></ul><p>The book was last updated according to current scientific understandings in 2013.</p><p>It's worth noting that not everyone is a subscriber to the book's structure. Popular astrophysics writer <a href="https://www.forbes.com/sites/ethansiegel/#30921c93683e" target="_blank">Ethan C. Siegel</a>, for example, published an article on <a href="https://www.forbes.com/sites/startswithabang/2019/07/26/we-have-already-entered-the-sixth-and-final-era-of-our-universe/#7072d52d4e5d" target="_blank"><em>Medium</em></a> last June called "We Have Already Entered The Sixth And Final Era Of Our Universe." Nonetheless, many astronomers find the quintet a useful way of discuss such an extraordinarily vast amount of time.</p>
The Primordial era<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTEyMi9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyNjEzMjY1OX0.PRpvAoa99qwsDNprDme9tBWDim6mS7Mjx6IwF60fSN8/img.jpg?width=980" id="db4eb" class="rm-shortcode" data-rm-shortcode-id="0e568b0cc12ed624bb8d7e5ff45882bd" data-rm-shortcode-name="rebelmouse-image" />
Image source: Sagittarius Production/Shutterstock<p> This is where the universe begins, though what came before it and where it came from are certainly still up for discussion. It begins at the Big Bang about 13.8 billion years ago. </p><p> For the first little, and we mean <em>very</em> little, bit of time, spacetime and the laws of physics are thought not yet to have existed. That weird, unknowable interval is the <a href="https://www.universeadventure.org/eras/era1-plankepoch.htm" target="_blank">Planck Epoch</a> that lasted for 10<sup>-44</sup> seconds, or 10 million of a trillion of a trillion of a trillionth of a second. Much of what we currently believe about the Planck Epoch eras is theoretical, based largely on a hybrid of general-relativity and quantum theories called quantum gravity. And it's all subject to revision. </p><p> That having been said, within a second after the Big Bang finished Big Banging, inflation began, a sudden ballooning of the universe into 100 trillion trillion times its original size. </p><p> Within minutes, the plasma began cooling, and subatomic particles began to form and stick together. In the 20 minutes after the Big Bang, atoms started forming in the super-hot, fusion-fired universe. Cooling proceeded apace, leaving us with a universe containing mostly 75% hydrogen and 25% helium, similar to that we see in the Sun today. Electrons gobbled up photons, leaving the universe opaque. </p><p> About 380,000 years after the Big Bang, the universe had cooled enough that the first stable atoms capable of surviving began forming. With electrons thus occupied in atoms, photons were released as the background glow that astronomers detect today as cosmic background radiation. </p><p> Inflation is believed to have happened due to the remarkable overall consistency astronomers measure in cosmic background radiation. Astronomer <a href="https://www.youtube.com/watch?v=IGCVTSQw7WU" target="_blank">Phil Plait</a> suggests that inflation was like pulling on a bedsheet, suddenly pulling the universe's energy smooth. The smaller irregularities that survived eventually enlarged, pooling in denser areas of energy that served as seeds for star formation—their gravity pulled in dark matter and matter that eventually coalesced into the first stars. </p>
The Stelliferous era<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTEzNy9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxMjA0OTcwMn0.GVCCFbBSsPdA1kciHivFfWlegOfKfXUfEtFKEF3otQg/img.jpg?width=980" id="bc650" class="rm-shortcode" data-rm-shortcode-id="c8f86bf160ecdea6b330f818447393cd" data-rm-shortcode-name="rebelmouse-image" />
Image source: Casey Horner/unsplash<p>The era we know, the age of stars, in which most matter existing in the universe takes the form of stars and galaxies during this active period. </p><p>A star is formed when a gas pocket becomes denser and denser until it, and matter nearby, collapse in on itself, producing enough heat to trigger nuclear fusion in its core, the source of most of the universe's energy now. The first stars were immense, eventually exploding as supernovas, forming many more, smaller stars. These coalesced, thanks to gravity, into galaxies.</p><p>One axiom of the Stelliferous era is that the bigger the star, the more quickly it burns through its energy, and then dies, typically in just a couple of million years. Smaller stars that consume energy more slowly stay active longer. In any event, stars — and galaxies — are coming and going all the time in this era, burning out and colliding.</p><p>Scientists predict that our Milky Way galaxy, for example, will crash into and combine with the neighboring Andromeda galaxy in about 4 billion years to form a new one astronomers are calling the Milkomeda galaxy.</p><p>Our solar system may actually survive that merger, amazingly, but don't get too complacent. About a billion years later, the Sun will start running out of hydrogen and begin enlarging into its red giant phase, eventually subsuming Earth and its companions, before shrining down to a white dwarf star.</p>
The Degenerate era<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTE1MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxNTk3NDQyN30.gy4__ALBQrdbdm-byW5gQoaGNvFTuxP5KLYxEMBImNc/img.jpg?width=980" id="77f72" class="rm-shortcode" data-rm-shortcode-id="08bb56ea9fde2cee02d63ed472d79ca3" data-rm-shortcode-name="rebelmouse-image" />
Image source: Diego Barucco/Shutterstock/Big Think<p>Next up is the Degenerate era, which will begin about 1 quintillion years after the Big Bang, and last until 1 duodecillion after it. This is the period during which the remains of stars we see today will dominate the universe. Were we to look up — we'll assuredly be outta here long before then — we'd see a much darker sky with just a handful of dim pinpoints of light remaining: <a href="https://earthsky.org/space/evaporating-giant-exoplanet-white-dwarf-star" target="_blank">white dwarfs</a>, <a href="https://earthsky.org/space/new-observations-where-stars-end-and-brown-dwarfs-begin" target="_blank">brown dwarfs</a>, and <a href="https://earthsky.org/astronomy-essentials/definition-what-is-a-neutron-star" target="_blank">neutron stars</a>. These"degenerate stars" are much cooler and less light-emitting than what we see up there now. Occasionally, star corpses will pair off into orbital death spirals that result in a brief flash of energy as they collide, and their combined mass may become low-wattage stars that will last for a little while in cosmic-timescale terms. But mostly the skies will be be bereft of light in the visible spectrum.</p><p>During this era, small brown dwarfs will wind up holding most of the available hydrogen, and black holes will grow and grow and grow, fed on stellar remains. With so little hydrogen around for the formation of new stars, the universe will grow duller and duller, colder and colder.</p><p>And then the protons, having been around since the beginning of the universe will start dying off, dissolving matter, leaving behind a universe of subatomic particles, unclaimed radiation…and black holes.</p>
The Black Hole era<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTE2MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYzMjE0OTQ2MX0.ifwOQJgU0uItiSRg9z8IxFD9jmfXlfrw6Jc1y-22FuQ/img.jpg?width=980" id="103ea" class="rm-shortcode" data-rm-shortcode-id="f0e6a71dacf95ee780dd7a1eadde288d" data-rm-shortcode-name="rebelmouse-image" />
Image source: Vadim Sadovski/Shutterstock/Big Think<p> For a considerable length of time, black holes will dominate the universe, pulling in what mass and energy still remain. </p><p> Eventually, though, black holes evaporate, albeit super-slowly, leaking small bits of their contents as they do. Plait estimates that a small black hole 50 times the mass of the sun would take about 10<sup>68</sup> years to dissipate. A massive one? A 1 followed by 92 zeros. </p><p> When a black hole finally drips to its last drop, a small pop of light occurs letting out some of the only remaining energy in the universe. At that point, at 10<sup>92</sup>, the universe will be pretty much history, containing only low-energy, very weak subatomic particles and photons. </p>

At around 2 p.m., they had tea in the hotel's garden and Monika took some snaps of Jimi with 'Black Beauty,' his favorite Fender Stratocaster guitar. Those were the last pictures ever taken of him. </p><p><span></span>Later in the afternoon, the couple went out – visiting local hipness hotspot <a href="https://en.wikipedia.org/wiki/Kensington_Market,_London" target="_blank">Kensington Market</a>, an antiques market in Chelsea and Jimi's suite at the Cumberland Hotel, near Marble Arch. They had tea and wine at a friend's flat, argued and made up, and went back to the Samarkand Hotel, where they had a late meal, drank a bottle of wine and Jimi wrote a poem titled 'The Story of Life.'</p><p>Well after midnight, Hendrix went to a party, where he took some amphetamine. Dannemann showed up at the party, and around 3 a.m. the couple returned to the Samarkand. Unable to sleep, Jimi took nine of Monika's sleeping pills (the recommended dose was half a pill). When she awoke that morning, she found him unresponsive and covered in vomit. Around noon of the 18th of September – exactly 50 years ago today – Jimi Hendrix was pronounced dead.</p><p>The last stanza of the poem he wrote the night before reads:</p><p style="margin-left: 20px;"><em>The story of life is quicker than the wink of an eye.</em></p><p style="margin-left: 20px;"><em>The story of love is hello and goodbye.</em></p><p style="margin-left: 20px;"><em>Until we meet again.</em></p><p>Amid the initial confusion surrounding his death, the poem was mistaken by some for a suicide note. Several subsequent investigations have provided nothing but indications of an accidental death. <br></p>

Earlier members include Robert Johnson (d. 1938) and Brian Jones (d. 1969), later ones Janis Joplin (who died two weeks after Hendrix), Jim Morrison (d. 1971), Kurt Cobain (d. 1994) and Amy Winehouse (d. 2011).</p><p>In the States, Hendrix had made a name for himself as a band guitarist, playing for both Little Richard and Ike Turner.
