Official NASA Live Earth Stream from the International Space Station
The Astrophyzix Live Earth Stream module provides a continuous public view of Earth as seen from cameras mounted on the exterior of the International Space Station (ISS) courtesy of our colleagues at NASA. The feed displays real-time orbital views of Earth captured from low Earth orbit approximately 400 kilometres above the planet’s surface.
This stream allows viewers to observe Earth from space in near real time as the station travels around the planet at an orbital velocity of roughly 28,000 kilometres per hour. The ISS completes one full orbit of Earth approximately every 90 minutes, resulting in about sixteen Earth orbits per day.
Camera Systems
Live Earth imagery from the ISS is produced by a set of external cameras mounted on the station's modules and experiment platforms. These cameras are designed to provide public outreach imagery and engineering observation views.
- External High Definition Camera (EHDC) mounted on the Harmony module
- Commercial ultra-high-definition cameras operated by private partners
- Historical High Definition Earth Viewing experiment cameras (HDEV)
The earlier High Definition Earth Viewing (HDEV) experiment operated between 2014 and 2019 and demonstrated the ability to stream continuous high-definition video from space before being retired. 0
Current live streams are typically produced using newer external HD cameras that transmit video to Earth through NASA’s Tracking and Data Relay Satellite communication network before being distributed publicly via internet streams.
What the Stream Shows
When the station passes over the sunlit side of Earth, the camera feed displays large-scale features of the planet including oceans, coastlines, deserts, mountain ranges, and cloud systems. As the station moves into darkness, viewers may observe city lights, lightning storms, auroras, and atmospheric airglow.
- Global weather systems and cloud formations
- Coastlines, islands and continental landmasses
- Atmospheric phenomena such as auroras
- Lightning storms and nighttime city illumination
- Spacecraft docked to the station and structural elements
Because the station orbits Earth roughly every ninety minutes, viewers can often witness multiple sunrise and sunset transitions within a short viewing session.
Signal Behaviour
The live video stream may occasionally display interruptions or switch to recorded footage. This can occur for several operational reasons associated with the space station's communications infrastructure.
- Temporary signal loss while switching communication satellites
- Station operations such as spacecraft docking or spacewalks
- Camera maintenance or system configuration changes
- The station entering Earth's night side where visibility is limited
These interruptions are a normal part of spaceflight operations and reflect the operational priorities of the station as an active research laboratory.
The International Space Station
The International Space Station is a permanently crewed orbital research laboratory developed through cooperation between multiple space agencies including NASA, Roscosmos, ESA, JAXA, and the Canadian Space Agency. The station has been continuously inhabited by astronauts since November 2000.
Orbiting at roughly 250 miles (about 400 kilometres) above Earth, the ISS provides a microgravity environment where astronauts conduct scientific experiments in fields including biology, physics, materials science, Earth observation, and technology development.
Educational Value
Live orbital video feeds provide a powerful educational perspective by allowing viewers to experience Earth from the same vantage point as astronauts in orbit. These views demonstrate the curvature of the planet, the thinness of Earth’s atmosphere, and the interconnected nature of global weather and geography.
- Understanding the scale of Earth from orbit
- Observing atmospheric and weather patterns
- Visualising orbital motion and spacecraft perspective
- Exploring the environmental appearance of Earth from space
- Supporting science communication and public outreach
