Orbiting 250 miles above Earth, the Worldwide Area Station (ISS) is humanity’s house in area and homes astronauts to conduct scientific analysis and observations. With the entire difficulties, pleasure, and strangeness, what do astronauts do everyday?
ISS Has Executed Over 3,000 Experiments
The ISS serves as the house and laboratory of astronauts in area throughout their mission—which you’ll track and see for yourself. There have been over 3,000 investigations carried out within the ISS through the years, in partnership with many nations internationally.
One of many targets of their research is to grasp the results of long-duration area flight on the human physique, in addition to developments in drugs. A few of these experiments have even improved medicine and cancer treatments, helped develop air purification and water filtration merchandise, and Earth commentary from the ISS has additionally helped with disaster relief.
Microgravity is a situation the place objects seem weightless.
Astronauts Develop Greens on the ISS
Do you know that gardening is possible inside the ISS? Astronauts have already efficiently grown lettuce, mustard greens, chili peppers, and radishes in area and even eaten them. Gardening not solely gives contemporary meals for astronauts but additionally contributes to our understanding of plant development in microgravity, which will likely be helpful once we determine to colonize one other planet.
The ISS has been frequently serving humanity by offering scientists and researchers a spot to conduct groundbreaking experiments and research, additional increasing human data. This additionally consists of rising edible uncooked supplies for human meals in preparation for future Mars and different long-duration missions.

The primary meals ever eaten in area was a beef and liver paste from a tube that Yuri A. Gagarin—the primary human in area, ate in 1961 aboard his Vostok capsule. This together with some chocolate sauce.
Astronauts Train 2.5 Hours a Day
A day in an astronaut’s life on the ISS is full of duties from upkeep of life-support techniques to supervising scientific experiments. However do you know that in addition they must train for two.5 hours every single day? That’s proper, 2.5 hours—appears to be like like even astronauts can’t skip a day on the health club. They’ve an intensive train routine to offset the muscle and bone density loss they expertise attributable to microgravity.
The best way astronauts train on the ISS is by getting harnessed to a treadmill (to remain in place whereas working) and foot clips for stationary bikes. To simulate weightlifting, they use the Advanced Resistive Exercise Device (ARED) that makes use of vacuum cylinders to supply resistance.
Astronauts Expertise 16 Sunsets a Day
One of many perks of being an astronaut is having the ability to view our planet Earth from a really totally different perspective. Astronauts get to expertise 16 sunrises and sunsets every day, because the ISS orbits Earth at a mind-boggling velocity of 17,500 mph, going round each 90 minutes. That feels like a very surreal expertise for astronauts.
The Cupola, a dome-shaped commentary module on the ISS, permits astronauts to take a panoramic view of area and Earth. Other than having that privilege, it’s additionally a spot to watch astronauts throughout spacewalks.

Spacewalks Can Final As much as 8 Hours
Spacewalking is not a easy stroll within the park. Formally generally known as Extravehicular Exercise or EVA, spacewalking is without doubt one of the most exhilarating duties an astronaut can take part in, however it’s not with out dangers.
Dangerous radiation, vacuum, and excessive temperatures are simply a number of the risks pressurized area fits have to beat to guard astronauts from spacewalks that may last as long as 8 hours.
Astronauts “stroll” exterior the ISS with security traces at all times tethered to them always to carry out their duties. Important work like upkeep of the ISS or upgrades are carried out and should embrace putting in new photo voltaic panels, attaching newly developed expertise, or repairing sure tools that’s important to the well being of the ISS.
Since security is of paramount significance for astronauts working in outer area, they put on SAFER backpack techniques, together with the security tether, as a backup for emergencies that permit them to maneuver their manner again to the area station. Rigorous preparations have been carried out by these astronauts on Earth for this sole objective. They practice on the Neutral Buoyancy Lab (NBL) of NASA to simulate weightlessness, coaching underwater for a lot of hours.

Astronauts spend 5–7 instances longer coaching within the NBL for every deliberate EVA.
Astronauts Experiment With 3D Printing
3D printing experiments done in space have proven some progress lately. In truth, the primary 3D printer was despatched to the ISS in 2014. This initiative brings hope in relation to fixing provide points throughout lengthy area journeys. If a alternative half is required throughout an area mission, astronauts could possibly simply print it utilizing a 3D printer.
One other helpful software of that is bioprinting. LamdaVision, a biotech firm, is attempting to develop the primary protein-based synthetic retina to revive imaginative and prescient for the blind or visually impaired. They’re engaged on this on the ISS since microgravity may also help with the layering of the proteins and polymers, which might be probably groundbreaking and result in treating retinal degenerative ailments and extra.
Astronauts Work With Robots and AI
NASA developed three cube-shaped robots named Honey, Queen, and Bumble (additionally known as the Astrobee system) to assist astronauts be extra environment friendly and help analysis on the ISS.
They’ve been operational since 2019 and may function autonomously (or be remotely managed) carry out stock administration, doc experiments, and assist with the upkeep of machines. These robots are anticipated to play a necessary function in caring for spacecraft for future deep area missions when astronauts are absent.
One cool factor concerning the Astrobee system is that it makes use of AI to autonomously carry out duties across the ISS, and consists of cameras and sensors to navigate across the ISS with out direct human help. These robots are additionally capable of detect radiation and carbon dioxide and acquire information autonomously.
Microgravity Isn’t All Enjoyable and Video games
Although this one isn’t essentially a cool factor that astronauts do in area, it actually highlights how a lot they undergo when working on the ISS.
Astronauts encounter important bodily well being challenges attributable to microgravity whereas dwelling and dealing in area. This consists of each muscle and bone loss. When astronauts get again to Earth, they will’t stand on their ft straight away and often want time to regulate to gravity once more. If they have been in area for a very long time, it may be weeks earlier than they’re on their ft once more.
However that’s just the start of how microgravity can have an effect on the human physique. Astronauts expertise accelerated ageing of illness, worsening eyesight, and pores and skin rashes. In the case of bone loss, they become 1% less dense for each month spent in area (in case you don’t have a rigorous train routine).
A former NASA astronaut, Dr. Sandy Magnus, as soon as described the sensation of launching into space after being requested by a toddler. Sandy mentioned it felt like having a “70-pound gorilla sitting in your chest.” This sense is the highly effective g-force that astronauts really feel when launching from Earth. You possibly can even watch some space launches soon.
Being an astronaut and figuring out of the ISS might be each bodily and mentally demanding. The work might be intense, and the situations of area don’t actually make it any simpler. Residing along with simply a lot of individuals in a confined area away from family and friends finally takes its toll. Fortuitously, video calls are possible from the ISS.
Astronauts assist present humanity with precious data that may additional push our boundaries not simply in area, but additionally on Earth as effectively—they usually get to do some fairly cool issues whereas doing it. There are additionally a lot of things that we wouldn’t have if it weren’t for space travel.
