Thermosphere.
The space station layer is in the mesosphere.
Space shuttles travel in the thermosphere, which is the second highest layer of the Earth's atmosphere. This layer extends from about 80 km to 550 km above the Earth's surface and is where the International Space Station orbits.
The thermosphere is the hottest layer in Earth's atmosphere, reaching temperatures as high as 2,500 degrees Celsius. It is located above the mesosphere and is where the International Space Station orbits.
The International Space Station (ISS) orbits within the thermosphere layer of the Earth's atmosphere. The ISS orbits at an average altitude of about 420 kilometers (260 miles) above the Earth's surface, within the thermosphere where the auroras occur and temperatures can reach thousands of degrees Celsius.
There is no current US space station. The last US space station was called SkyLab - but it entered Earth's atmosphere in 1979. The US (through NASA) currently uses the International Space Station or ISS.
The fourth layer of the Earth's atmosphere is termed the Thermosphere. This layer is located at an altitude of about 80-550 km above the Earth's surface and is characterized by increasing temperatures due to absorption of solar radiation. It is where the International Space Station orbits.

about 350 miles is where the international space station is.
The International Space Station (ISS) orbits in the thermosphere, which is located approximately 300 to 400 kilometers (about 186 to 248 miles) above the Earth's surface. This layer of the atmosphere is characterized by high temperatures and low atmospheric density. The ISS travels at a speed of around 28,000 kilometers per hour (17,500 miles per hour) in this layer, allowing it to complete an orbit around the Earth roughly every 90 minutes.
The thermosphere is the hottest layer of Earth's atmosphere. The molecules there are directly exposed to solar radiation and high-energy cosmic rays. However, there are so few molecules by volume that the specific heat is virtually zero. The thermosphere is generally located 85 to 500 km above the Earth, and the International Space Station orbits in the outer thermosphere (330 to 450 km altitude).
That portion of the atmosphere is within the Thermosphere layer. The Thermosphere is known for its high temperatures due to the absorption of solar radiation, with temperatures increasing with altitude. It is also where the International Space Station orbits.
The International Space Station (ISS), which orbits at between 187 and 194 nautical miles (about 215 to about 223 miles), is in what is called the thermosphere. We know that this layer, which is above the mesosphere and below the exosphere, extends from about 100 kilometers (a bit over 60 miles) to 690 kilometers (a little less than 430 miles) above the surface of the earth.
