The British company Sen has launched a commercial 4K live stream from space, the very first of its kind. The stream offers unprecedented views of Earth from the International Space Station, the same view astronauts get to see every day (ISS). The initiative began in January of 2025, and aims to take the perspective of an astronaut and make it more accessible through Ultra High Definition streaming.
“We’re excited to share these amazing 4K live views of Earth. This mission really is for all humanity,” announced Sen founder and CEO Charles Black. He also highlighted the company’s vision to “inform, educate, inspire and benefit humanity”. The company expects billions to come use the platform, marking a major democratization when it comes to space observation.
The streaming service uses SpaceTV-1, a camera system mounted on the ISS’s Bartolomeo platform (more specifically on the European Space Agency’s Columbus module). The setup has three different cameras, each giving a unique perspective of Earth’s beauty from space.
The first camera has a panoramic wide-angle lens, which can capture Earth’s horizon, while the second records Earth from above, covering a roughly 240 km x 180 km area with remarkable detail – each pixel representing roughly 60 meters of ground. The third camera faces forward and focuses on the ISS’s Harmony module docking port, giving viewers a look into how space operations take place.
Coverage covers about 20 hours daily, with interruptions due to signal loss between the satellite relay on the ground and the space communications unit. Users can access the stream through Sen’s website and various streaming platforms, including YouTube.
The Overview Effect and Human Perspective
The initiative goes beyond entertainment, as it gives viewers a chance to feel what astronauts call the “overview effect“ – a cognitive shift experienced when viewing Earth from space. This phenomenon, described as “a sense of awe with self-transcendent qualities,” often leads to “an increased sense of connection to other people and the Earth as a whole”.
Astronauts who have experienced this effect have reported profound changes in their view of Earth and humanity. Many have described overwhelming emotions and a newfound sense of connection to the planet and its inhabitants. Through Sen’s streaming service, viewers might also be able to experience this transformative perspective.
These high-definition space views could revolutionize space education and public engagement with space science. By making the stream free to view, Sen hopes to help bridge the gap between professional space exploration and public understanding.
The platform’s impact could be significant, offering teachers and students an incredible tool for learning about Earth science, astronomy, and space technology. Plus, having a stream in real-time adds an element of immediacy and relevance to space education.
Innovation and Global Perspective
Sen has ambitious plans to continue expanding its space observation capabilities. The company is developing its own satellite, the ETV-A1, with more satellite projects on the way designed to enhance space streaming capabilities. These developments are expected to launch by 2026 and promise to deliver even more breathtaking, educational views of Earth from space.
The platform also serves a crucial function in environmental observation, allowing the public to “witness planetary change” in real-time. This could prove invaluable for environmental awareness and education, allowing people to see global weather patterns, environmental changes, and natural phenomena as they unfold.
This technological achievement represents more than just a streaming service; it’s a window into humanity’s shared existence on our planet. The ability to view Earth from space in real-time could foster a greater sense of global unity and environmental responsibility. The company currently has a partnership with the ISS and has contracts with Airbus and other various space agencies.
