What India looks like from the space station, and when you can see it from India

From the International Space Station, about 420 km up, the horizon lies roughly 2,250 km away in every direction. When the station passes over central India, that puts almost the whole country in view at once: Srinagar and Thiruvananthapuram, Karachi and Dhaka, Kathmandu and Colombo all sit inside the same circle. Our calculation puts the area in view at any moment at about 15.8 million square kilometres, nearly five times the size of India.

Can you see India from the ISS?

Yes, and often. The station’s orbit is tilted 51.6 degrees to the equator, so its track sweeps between 51.6° north and 51.6° south. All of India lies between about 7° and 37° north, well inside that band, so the ISS passes over every part of the country. It travels at about 7.66 km per second; the point beneath it moves across the ground at about 7.2 km per second. Crossing India from Kanyakumari to Kashmir, about 3,214 km, takes roughly seven and a half minutes.

What can astronauts actually see?

A sharp human eye can separate details about one arcminute apart. From 420 km straight down, one arcminute spans about 120 metres on the ground. That sets the scale. Rivers like the Ganga and the Brahmaputra, the edge of the Himalayan snow, the Thar Desert, the white salt of the Rann of Kutch, large dams, airport runways and the shapes of cities are all clear to the eye. Individual buildings, roads in towns and the Great Wall of China, a few metres wide, are not. Astronauts’ cameras with long lenses resolve far more than their eyes do, which is why their photographs show detail they could not have seen directly.

At night India is mapped by its lights. The Delhi region, the Mumbai–Pune corridor and the cities of the Gangetic plain stand out, and astronauts have long photographed the lit fence along the India–Pakistan border, which shows as a bright line from orbit. In winter the northern plains can vanish under a sheet of fog visible from space.

“Saare jahan se achha”

In April 1984 Rakesh Sharma, the first Indian in space, was asked by Prime Minister Indira Gandhi during a live link from the Soviet Salyut 7 station how India looked from up there. His answer, “saare jahan se achha”, better than the whole world, became one of the best-known lines in Indian spaceflight. Forty-one years later, in his farewell from the ISS on 13 July 2025, Shubhanshu Shukla answered the same question in his own way: India from space, he said, looked ambitious, fearless, confident and proud, and still “saare jahan se achha”.

When can you see the ISS from India?

You do not need a telescope. The ISS looks like a very bright, steady star gliding across the sky over a few minutes, brighter than any star at its best, with no blinking lights. You can only see it when two things are true at once: you are in darkness and the station, high above you, is still in sunlight. That happens only in the hours after sunset and before sunrise.

We worked out how long that window lasts. For a pass directly overhead, the station stays lit until the Sun is about 20 degrees below your horizon. In India that takes 80 to 110 minutes after sunset, depending on the city and the season. So the best passes come in roughly the first hour and a half after dark, or the last hour and a half before dawn. Unlike places much farther north, India never gets passes in the middle of the night.

• NASA’s free Spot the Station service lists upcoming visible passes for Indian cities, with the direction, height and duration of each.
• Predictions are accurate a few days ahead. The station’s orbit is adjusted from time to time, so check again shortly before a pass.
• The best passes are those with a high maximum height. Low passes near the horizon are dimmer and easily lost in haze.
• If you see a bright, steady point fade out in the middle of the sky, that is the station entering Earth’s shadow.

Only a few years left

The ISS is due to be retired around 2030, and NASA has contracted SpaceX to build a vehicle to steer it safely into the ocean. India plans to have the first module of its own station, the Bharatiya Antariksh Station, in orbit by 2028, and its first astronauts flying on Gaganyaan before then.

How we worked this out

The horizon distance is the arc of Earth’s surface, radius 6,371 km, visible from a height of 420 km: R·arccos(R/(R+h)), about 2,252 km. The area is that of the spherical cap. Orbital and ground speeds are for a circular orbit at 420 km. The ground resolution assumes the eye separates one arcminute. The sunlit window is the time from sunset until the Sun is 20.3 degrees below the horizon, the angle at which Earth’s shadow reaches 420 km straight overhead, calculated with the open-source Astronomy Engine library for each city on the solstice and equinox dates. India’s north–south extent is the government figure. The 1984 and 2025 remarks are as widely reported at the time.
