2. What is Orbital Velocity?
Orbital velocity is the speed at which an object must travel to maintain a stable orbit around a celestial body, such as a planet or a star. This velocity is determined by the balance between the gravitational pull of the celestial body and the inertia of the orbiting object. If an object moves too slowly, gravity will pull it down, causing it to fall back to Earth. If it moves too quickly, it will escape the gravitational pull and drift into space.
The formula to calculate orbital velocity is:
v = √(GM/r)
Where:
vis the orbital velocityGis the gravitational constant (approximately 6.674 × 10-11 Nm²/kg²)Mis the mass of the celestial body (e.g., Earth)ris the distance from the center of the celestial body to the orbiting object
Understanding orbital velocity is essential for planning and executing space missions. It allows scientists and engineers to precisely calculate the necessary speed and trajectory for spacecraft to reach their destinations and maintain stable orbits.
3. How Fast Does the International Space Station Travel?
The International Space Station travels at an average speed of 17,500 miles per hour (28,000 kilometers per hour). This mind-boggling velocity allows the ISS to orbit Earth approximately every 90 minutes, completing around 16 orbits per day. The ISS needs to maintain this speed to counteract Earth’s gravity and remain in a stable orbit.
To put this speed into perspective, consider that a commercial jet typically flies at around 500-600 miles per hour. The ISS is traveling nearly 30 times faster. This incredible speed is necessary to counteract Earth’s gravity and maintain its orbit at an altitude of around 250 miles (400 kilometers).

4. Factors Affecting the ISS Speed
Several factors influence the speed and orbit of the International Space Station, including altitude, atmospheric drag, and orbital maneuvers. These elements require constant monitoring and adjustments to ensure the ISS maintains its intended path.
4.1. Altitude
The altitude of the ISS significantly impacts its orbital speed. The closer an object is to Earth, the stronger the gravitational pull, and therefore the faster it needs to travel to maintain its orbit. Conversely, the higher the altitude, the weaker the gravitational pull, and the slower the required speed. The ISS typically orbits at an altitude of around 250 miles (400 kilometers), which necessitates its high velocity of 17,500 miles per hour.
4.2. Atmospheric Drag
Although the ISS orbits in space, there is still a very thin atmosphere at its altitude. This atmosphere creates a slight drag on the station, gradually slowing it down over time. To counteract this atmospheric drag, the ISS periodically performs reboost maneuvers, using its engines or those of visiting spacecraft to raise its altitude and increase its speed.
4.3. Orbital Maneuvers
Orbital maneuvers are planned adjustments to the ISS’s orbit. These maneuvers are necessary to avoid collisions with space debris, maintain the correct altitude, and align the station for visiting spacecraft. They involve firing the station’s engines for a specific duration to change its velocity and trajectory. These maneuvers are carefully calculated to ensure they achieve the desired outcome without disrupting the station’s operations.
5. How the ISS Maintains Its Speed
Maintaining the ISS’s speed is a complex process that requires constant monitoring and adjustments. The primary method for maintaining speed is through reboost maneuvers. These maneuvers are typically performed every few months and involve firing the engines of the ISS or a visiting spacecraft for a short period.
5.1. Reboost Maneuvers
Reboost maneuvers are essential for counteracting the effects of atmospheric drag and maintaining the ISS’s altitude and speed. These maneuvers are carefully planned and executed to ensure they achieve the desired outcome without disrupting the station’s operations. The timing and duration of the engine firing are precisely calculated to raise the station’s altitude and increase its speed.
5.2. Visiting Spacecraft
Visiting spacecraft, such as the Russian Progress cargo ships, can also be used to perform reboost maneuvers. These spacecraft dock with the ISS and use their engines to raise the station’s altitude. This is a convenient way to perform reboost maneuvers, as it does not require the ISS to use its own limited supply of fuel.

6. Implications of the ISS Speed
The speed of the ISS has several significant implications for its operations and the astronauts who live and work there. These implications range from the frequency of sunrises and sunsets to the challenges of docking spacecraft.
6.1. Frequency of Sunrises and Sunsets
Because the ISS orbits Earth every 90 minutes, astronauts experience approximately 16 sunrises and 16 sunsets each day. This rapid cycle of light and darkness can disrupt their circadian rhythms and affect their sleep patterns. Astronauts must carefully manage their schedules and use artificial lighting to maintain a regular sleep-wake cycle.
6.2. Docking with the ISS
The high speed of the ISS presents a significant challenge for spacecraft attempting to dock with it. Spacecraft must precisely match the ISS’s speed and trajectory to achieve a successful docking. This requires sophisticated navigation and control systems, as well as highly trained pilots.
6.3. Scientific Research
The speed of the ISS also affects the scientific research conducted on board. The microgravity environment created by the station’s constant freefall allows scientists to conduct experiments that would be impossible on Earth. These experiments can provide valuable insights into various fields, including biology, physics, and materials science.
7. How the ISS Speed Affects Time Perception
The high speed of the International Space Station (ISS) not only impacts its orbit but also affects the astronauts’ perception of time. This phenomenon is rooted in Einstein’s theory of relativity, which posits that time is relative and can be influenced by speed and gravity.
7.1. Time Dilation
According to Einstein’s theory of special relativity, time dilation occurs when an object moves at a significant fraction of the speed of light. The faster the object moves, the slower time passes for it relative to a stationary observer. While the ISS’s speed of 17,500 miles per hour is not a significant fraction of the speed of light, it does result in a slight time dilation effect.
7.2. Gravitational Time Dilation
Einstein’s theory of general relativity also describes gravitational time dilation, which occurs when an object is in a region of weaker gravity. The ISS orbits Earth at an altitude of approximately 250 miles (400 kilometers), where the gravitational field is slightly weaker than on the Earth’s surface. This means that time passes slightly faster on the ISS than on Earth.
7.3. Combined Effect
The combined effect of special and general relativity on the ISS results in a time difference of approximately 0.01 seconds per year compared to Earth. While this difference may seem negligible, it can accumulate over long periods and must be taken into account for precise scientific measurements and navigation.
8. The Future of Space Travel and Speed
