Space Live Counters
From the ISS to the edge of the observable universe – watch cosmic activity unfold in real time.

The Universe in Motion
Space is anything but empty. Every second, our planet hurtles through the cosmos, bombarded by cosmic rays, illuminated by solar energy, and accompanied by thousands of orbiting satellites. These counters reveal the invisible, ceaseless activity happening above our heads.
Life Aboard the ISS
Since November 2000, humans have maintained a continuous presence in space aboard the International Space Station. Orbiting at 408 km altitude, the ISS completes 16 orbits daily while hosting groundbreaking experiments in microgravity, biology, and materials science. Over 270 astronauts from 20 countries have called it home.
Earth's Cosmic Journey
We tend to think of Earth as stationary, but our planet moves at extraordinary speeds. It orbits the Sun at 107,000 km/h, while the solar system orbits the Milky Way's center at 828,000 km/h. Even the galaxy itself moves at 2.1 million km/h relative to the cosmic microwave background. Every second, you travel 30 km through space.
The Satellite Constellation
Over 6,000 active satellites orbit Earth, providing everything from GPS navigation to weather forecasting. SpaceX's Starlink constellation alone accounts for thousands. However, this proliferation raises concerns about space debris – over 30,000 tracked objects and millions of smaller fragments pose collision risks.
Cosmic Bombardment
Earth is constantly bombarded by particles from deep space. Cosmic rays – high-energy protons and atomic nuclei – strike our atmosphere at nearly the speed of light. Most are harmlessly absorbed, but they produce secondary particles detectable at ground level. These cosmic visitors carry information about supernovae, black holes, and the most violent events in the universe.
Solar Power on a Cosmic Scale
The Sun delivers roughly 174,000 terawatts of energy to Earth's surface – about 10,000 times humanity's total energy consumption. In just one hour, enough solar energy reaches Earth to power all of civilization for an entire year. Harnessing even a fraction of this bounty could solve our energy challenges forever.
Data Sources and Methodology
Our space statistics are sourced from NASA, the European Space Agency (ESA), the International Meteor Organization, CERN, and peer-reviewed astrophysics journals. Orbital speeds and distances use well-established physics constants, while cosmic event rates represent best scientific estimates.
