The International Space Station (ISS) is an international partnership of five space agencies from 15 countries that operates the planet. Several patches, measuring 2 by 2 inches (5 by 5 cm), will be shipped to the ISS aboard a SpaceX Dragon cargo capsule in October and attached to the orbiting lab’s. The ISS is the largest orbital outpost in the world, with crew members living and working aboard it 16 times a day.
The construction of the ISS was impossible due to the lack of a rocket big enough or powerful enough. However, the Space Station was built to provide a comfortable environment for astronauts, as they can’t eat or scratch and feel no gravity. The ISS is located in both the upper atmosphere and in space, with astronauts experiencing about 89 of the force of gravity of Earth.
The heat in space is more challenging than the cold, as it is difficult to get rid of excess heat without an atmosphere protecting it. Without an atmosphere protecting it, the ISS is subjected to enormous temperature variations and intense radiation. In one lesson, students can navigate a 3D model of the interior and exterior of the ISS and face spontaneous challenges to solve in real time. The space station is 356 feet end-to-end and has eight miles of surface.

Are there cracks in the ISS?
Russian cosmonauts have identified the emergence of new cracks in a segment of the International Space Station (ISS) that could potentially widen, marking the latest in a series of challenges encountered in the ongoing maintenance and upkeep of the ISS.
Is the ISS made of steel?
The International Space Station (ISS) project, involving sixteen countries, faced numerous engineering challenges due to language, culture, politics, and differences in processes, management, and communication. The ISS agreement program required the station components to be durable and versatile, as they were intended for astronauts indefinitely. To address these challenges, new engineering and manufacturing processes and equipment were developed, and shipments of materials were needed for the construction of the space station components.
The project began as Space Station Freedom, a US-only effort, but was delayed due to funding and technical issues. In 1993, the US and Russia agreed to merge their separate space station plans into a single facility, incorporating contributions from the European Space Agency and Japan. Later, an international agreement board recruited additional space agencies and companies to collaborate on the project.
The International Organization for Standardization played a crucial role in unifying and overcoming different engineering methods, languages, standards, and techniques to ensure quality, engineering communication, and logistical management across all manufacturing activities of the station components.
How thick is the glass on the ISS?
The Cupola windows on the International Space Station (ISS) are composed of four panes, with individual layers ranging in thickness from 0. 5 to 1. 25 inches. Additionally, there are vacuum and pressure spaces between the layers, which collectively total approximately 5 inches.
How hot does the outside of the ISS get?
The temperature fluctuations experienced by the International Space Station (ISS) can reach up to 300 degrees Celsius, with the temperature on the sunny side reaching 121 degrees Celsius (250 degrees Fahrenheit) and dropping to -157 degrees Celsius (-250 degrees Fahrenheit) on the shady side.
Is there AC in the ISS?
The International Space Station (ISS) uses three forms of cooling: radiators that release heat, air conditioning, and reflective paneling. These cooling systems are crucial for astronaut comfort and experiments. Solar arrays and radiators were either pre-assembled on a module or launched on the space shuttle, and crew members attached them to the station. Battery replacements are done over spacewalks, which are designed and practiced to ensure safety and efficiency.
Assembly in space is unique, as even simple spacewalks can take hours due to the difficulty of operating in space. The ISS Engineering Feat series provides more information on design, solar array repair, and robotics.
What is the exterior of the ISS made of?
The International Space Station (ISS) is primarily constructed from aluminum, with Node modules fabricated from single aluminum blocks. Some surfaces are covered with debris protection blankets, which are composed of Nextel or Kevlar.
How thick are ISS walls?
The spacecraft designed for use by astronauts features walls with a thickness of 10 centimetres, comprising an inner and outer aluminium shell with a thickness of 0. 3 centimetres. The walls are separated by a layer of polyurethane, which serves to enhance the radiation shielding properties of the spacecraft.
Can you boil water on the ISS?
NASA and Rensselaer Polytechnic Institute researchers discovered that even when water was 160 degrees above its boiling point, the microgravity of the International Space Station (ISS) kept it in its liquid form. This was due to safety reasons, as astronauts couldn’t force boiling by increasing the temperature. Superheated fluids, which remain above their boiling point, can cause explosions if exposed to lower pressures or temperature increases. The team is still unsure why the water is refusing to boil up there, but they have an intriguing hypothesis.
What is the Russian leak on the ISS?
In December 2022 and February 2023, coolant leaks from a Soyuz crew capsule and Progress supply ship were discovered, with Russian investigations concluding that the leaks were likely caused by meteoroids rather than manufacturing flaws. The space station, a symbol of post-Cold War international cooperation, is now one of the last remaining areas of cooperation between Russia and the West amid tensions over Moscow’s military action in Ukraine. NASA and its partners aim to continue operating the orbiting outpost until 2030.
Will the ISS eventually fall?
NASA plans to replace the International Space Station (ISS) with a private space station by 2030, aiming to ensure nothing within Earth’s orbit remains in space forever. The new space station will be owned, built, and operated by companies like Axiom Space, Voyager Space, or Blue Origin, each receiving hundreds of millions of dollars in funding and sharing their expertise. NASA will eventually select one company to officially partner with and replace the ISS, focusing on deep space exploration, a more challenging task.
How thick is the shell of the ISS?
Harmony is the second of three node modules on the United States Orbital Segment (USOS). It is made of a cylindrical, 5. 1 cm thick 2219-T851 aluminium alloy pressure shell with two endcones and is thermally insulated by a goldised Kapton blanket. It is protected from micrometeoroids by 98 panels made from a composite sandwich of stainless steel and 6061-T6 aluminium alloy, and a secondary barrier of Kevlar/ resin. The design is based on the existing Multi-Purpose Logistics Module and the European Space Agency’s Columbus module.
Harmony is managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama. Its deployment expanded the Space Station, allowing it to grow from the size of a three-bedroom house to the space equivalent of a typical five-bedroom house. The Space Station robotic arm, Canadarm2, can operate from a powered grapple fixture on the exterior of Harmony.
Harmony is equipped with eight International Standard Payload Racks, four avionics racks and four for stowage or crew quarters. After the cancellation of the Habitation Module, Harmony was chosen to house the American Crew Quarters. The company Thales Alenia Space built Harmony in an agreement between NASA and the European Space Agency. It arrived at the Kennedy Space Center in Florida on 1 June 2003.
📹 Can you feel the speed at which the ISS travels?
Frank De Winne is answering a question on the ISS submitted by Paul from Portugal: When you do your EVA (space walk), can …
“We are made of stellar ash. Our origin and evolution have been tied to distant cosmic events. The exploration of the cosmos is a voyage of self-discovery. I believe our future depends powerfully on how well we understand this cosmos in which we float, like a mote of dust in the morning sky.” – Carl Sagan
When the ISS passes over my home it is amazing how fast it appears to move through star fields and clouds. I think the longest it has been visible under the best conditions is 4-5 minutes, but usually much less. I remember the balloon like Echo satelite which orbited so high (~1000 miles) was visible for up to 15 minutes. Enjoyed this ESA article and thanks.
It’s actually because of the law of inertia: when you leave objects alone, they travel with constant velocity. Constant speed is relative, so in you car or in your space station you don’t feel because you can consider yourself at rest relative to your vehicle. For the ISS add Einstein’s principle of equivalence: you can’t feel gravity if you are in free fall, as objects in orbit are. Oh, nevermind…
I’m likely being really dumb here, but there’s one thing I don’t get. Once they open the hatch, I understand they don’t feel the resistance of 8 km/s, as there is no resistance. However, that surely must mean that they need to be somehow connected to the ISS at all times, in other words – if the cord and cables with which they are attach would somehow detach, then the ISS would leave them behind at the rate of 8 km/s (or a little less, as the detached astronaut would likely still be hurling through space at maybe 7.8 km/s from the time of detachment)?
So he’s flying 28.000 km/h around the Earth.At the same time he’s flying 107.000 km/h around the Sun.At the same time he’s flying with the Solar system at speed of 820.000 km/h around the center of the Milky Way.And at the same time he’s flying 2.100.000 km/h through the space with the Milky Way. And to think that there’s even more..
Most astronauts seem to be very pleasant persons. Well, I suppose this is an important criteria to select them: For PR reasons (As humans in space are far more a problem than a solution, the happy few must make us dream, and I feel personally truely payed off with this kind of article: This is happening, nothing to do with Hollywood special effects or a computer simulation), but first of all for team work efficiency. Like on a boat or in a submarine, altruism is a virtue. Thanks, Frank de Winne!
PlotTwist: The astronaut and the iss is same speed, unless the iss starts using boosters or slows down Fact: You can try this in kerbal space program Earth orbit speed is 8km/s and iss is going 7,66km/s or 27.576 km/h but in this article youtu.be/p9XandILnvk at 8:08 is going 143.845m/s thats 155,43km/h thats 5 times speed of iss!
It is not just humans that don’t feel speed, nothing does. It is called equilibrium and it means you have no change of speed or equivalently that all the force vectors applied are canceling each other. Also earth is turning on it axis and around the sun at an even greater speed and the solar system turns around the center of our galaxy and so on.. You cannot feel that right?
But how the human travels at same speed as ISS while he is not attached to it,, because the human body is free in the space, there is no connection between the body and the spaceship, so the body should be constant, and the ISS moves alone, or he should be attached with a wire or something,, anybody understands what I mean??? This question kills me,, I haven’t found any answer
All that is related with “feeling” the speed is any kind of resistance and what your eyes see.On Earth you can not reach the speed of light with a plane because of air resistance – the plane will burn like a ball of fire. In space you have no resistance so if you have the power to reach the speed of light you should only avoid meteorites ( with the speed of light I think it will be quite tricky 😉 ). We have a lot more to learn and grow. Science for a better life ! Remember this.
Does anybody know physics well enough to know if the ISS orbital velocity is the same when they time their complete orbit using an ISS clock, as it is when calculated using a ground-based clock? If velocity is in m/s I am wondering if their circumference time is clocked as shorter than we would clock it here on the surface, due to time dilation. The orbit circumference is obviously a fixed number, so if the time elapsed is different depending on where it is measured, which orbital velocity (m/s) is “correct”?
We can’t feel speed when we’re moving at a constant speed even if that speed is close to the speed of light. We can feel it when speed changes (speed up or slow down or change direction), though. So in an airplane you don’t feel anything when you’re cruising, but during take off when you’re speeding up you’ll feel like you’re being pulled down into your seat. Unfortunately you can’t go at the speed of light unless you have no mass. Blame Einstein for that one.
