International Space Station

The International Space Station (ISS) cost an estimated $150 billion to build and maintain over the past two decades. This cost was shared among multiple countries participating in the project, including the United States, Russia, Europe, Japan, and Canada.

The Earth is round, but the maps that those diagrams are on are flat. The International Space Station uses a circular orbit, but when the route is shown on a flat surface it appears in a wave formation. If you draw a line around a fruit that you can easily peel and then peel the fruit and try and lay it out flat, you will see that the line is in a wave. The Earth is also rotating, so as the International Space Station orbits the Earth the places it passes over changes, which also has an affect on how the route appears.

The International Space Station (ISS) project began in 1998 with the launch of the first module. However, discussions and planning for the ISS date back to the 1980s during the Cold War era. It involved collaboration between various countries, including the United States, Russia, Europe, Japan, and Canada.

The International Space Station (ISS) was created as a joint effort between multiple countries, including the US, to conduct research in space, advance scientific knowledge, and promote international cooperation in space exploration. The US contributed to the ISS project to maintain a presence in space, research new technologies, and further human exploration beyond Earth.

The primary forces acting on the International Space Station while in orbit are gravitational force, which keeps it in orbit around Earth, and drag force from the thin atmosphere at higher altitudes, which causes a slight decay in its orbit over time. Additionally, minor forces such as solar radiation pressure and tidal forces from Earth also affect the station.

I think the LEO (Low Earth Orbit) is economical than higher Earth Orbit for the ISS. The rocket is able to send heavier spacecraft to LEO.

But spacecraft in LEO is sinking because of air drag. The ISS has to boost the orbit from time to time (for example several weeks ). The air drag is smaller in higher Earth Orbit.

The International Space Station can be sighted when it flies over the region you are in.

The website in related links below will tell you when the international space station can be observed in your region. It looks like a moving star, when you walk its like something out of the blue is above you.

Yes, there is internet on the International Space Station (ISS). Astronauts can access the internet through a special connection that interfaces with the ground. However, the internet speed is limited and can be slower than what we are used to on Earth.

ALL 16 nations The ISS programme is a joint project among the space agencies of the United States (NASA), Russia (RKA), Japan (JAXA), Canada(CSA) and ten Europeannations (ESA). The Brazilian space agency(AEB) participates through a separate contract with NASA. The Italian space agency(ASI) similarly has separate contracts for various activities not done within the framework of ESA's ISS projects

The ISS began construction in 1998, so (as of 2009) it is about 11 years old.

Space stations can appear bright in the night sky because they reflect sunlight off their solar panels and metal surfaces. This reflection can make them appear as bright, moving objects as they orbit the Earth.

Astronauts on the International Space Station recycle almost all of their water. Urine and sweat are collected and purified through a system called the Water Recovery and Management system. This system removes contaminants and recycles the water for consumption. Additionally, water is brought to the space station periodically by resupply missions.

Two other space stations that have orbited Earth in the past are Mir, which was operated by the Soviet Union and later Russia, and Skylab, which was operated by NASA. Both stations played important roles in advancing human space exploration.

Several reasons: to make for a training place for Astronauts to actually learn to live in free-fall for long periods of time, a place to do experiments, a stopping point or a "warehouse" for other programs, a storage facility, a telescope (radio, visual, xray, infrared and ultraviolet.)

For sending men to Mars mission it will take at least 3 years (the whole thing- get there do stuff, get back) so we need a real training facility to prepare the Astronauts. A space station is a good place to make hops from: from surface to low earth orbit, orbit to the moon. The moon to Mars. Mars to the Asteroids. Asteroids to the moons of Saturn and Jupiter. Each big jump can be made safer for humans by having working stations between each location. It's slow, expensive and slow. But better slow than never.

What you see is the sun's light being reflected off it. This is the same for any satellite. As it passes it first starts to reflect more light at you so it gets brighter, and then it starts to reflect less light and slowly appears to fade away. It doesn't have any flashing lights, which is how you know it is a satellite and not a plane. It is the largest man made object orbiting us, so it is the brightest satellite. You can see other satellites in the same way, brightening up and then fading away, but as they are smaller, they reflect less light back and don't look as bright.

The International Space Station is constantly circling the earth. It is in a state of freefall, meaning that it is literally "Falling" around the earth. Since the station falls at an angle relative to the ground, it will stay on a constant circular path around the earth, until some other force alters its path.

In microgravity, crystals can grow larger, more accurately, and with a much more perfect structure than on Earth. On Earth, gravity has a huge impact on crystal growth, which causes crystals to have defects.

On the space station, protein crystals are grown to assist scientists in discovering how to make new drugs, which could potentially cure even tough diseases like HIV.

First proteins are dissolved in a concentrated solution inside the Advanced Protein Crystallization Facility (APCF) on the space station. Over a period of several weeks or even months, the concentration grows into protein crystals. The protein crystals are then returned to Earth where X-rays are shined through them to produce a diffraction pattern. A diffraction pattern is a map of the intensity of the X-rays after they have been reflected through the crystal. From the diffraction pattern, an electron density map is produced. The x-rays actually bounce off the electron cloud which from the outer structure of each atom. From the electron density pattern, the structure of the proteins can be calculated. The models produced of the protein structure can be used to find receptor sites and active areas where molecules would react with other molecules. This information can be used to design drugs that can either help or stop the proteins without affecting the rest of the body.

It takes about 90 minutes for it to do one orbit of the Earth, so it can go around Earth about 16 times a day.

The four basic requirements to make a space station habitable are: oxygen for breathing, temperature control for comfort and equipment operation, radiation protection to shield from harmful cosmic rays, and a reliable source of food and water for sustenance.

The International Space Station (ISS) stays in orbit and moves because of its initial velocity from its launch into space and the lack of significant air resistance in space. It continues to orbit Earth due to the balance between its forward momentum and the gravitational pull of the Earth. Additionally, occasional rocket burns are used to adjust the ISS's orbit and altitude as necessary.

The International Space Station can typically be seen from Akron, Ohio early in the morning or late at night when it reflects sunlight and is visible as a bright light moving across the sky. There are websites and apps that can help you track the ISS passover times for your specific location.

The International Space Station orbits the Earth about 16 times a day, taking roughly 90 minutes to complete one orbit.

It is unknown. What has been proven though is that Mars used to have an atmosphere similar like earth (this is necessary to support life) also it is possible that mars has had liquid water before (pressure is needed to keep it in liquid form, and pressure comes from atmospheres), which is also necessary for life, as far as we know. (dried up riverbeds and channels are found on mars surface). in addition to the possible past liquid water, it is also a theory that mars has water still, wether in gas or solid form underneath the surface. A possible fossilized rock has been found as well. the rock has not been proven to be an actual fossil, but many people think it is fossilized bacteria, or in other words, life. If it IS bacteria, it is does not necessarily prove that it came from mars though. It could have come from earth due to the theory that mars and earth collided in early years, or come from earth from an impact big enough to send rock into space, then mars pulled it with its gravity. it is possible that it has come from another planet/object as well. Life on Mars is a big mystery. Mars is the planet most like earth, and the planet most likely to be able to support life as well, but it is still unproven that there has been life on mars, or even if there IS life on mars.

Astronauts sleep in sleeping bags that are tethered to the walls so they don't float around in microgravity. They can sleep in any orientation - standing, sitting, or floating. They also wear eye shades and earplugs to help them get quality rest despite the constant lighting and noise in the space station.
