A live counter showing how far Earth has carried you through its orbit since this page loaded — about 29.8 kilometres every second. Below it, a flight-path arc bounces a dot between Prague and Amsterdam (about 890 km apart) to give the distance a human-scale reference; the dot completes one crossing roughly every 30 seconds.
Earth's orbital speed around the Sun: ~29.8 km/s
An Earth-rotation clock: how far the planet has turned since the most recent sunrise in Prague, shown as an arc of a full 360-degree turn, with an estimate of how far that has carried you east. You can travel through time with the keyboard — D moves forward, A moves back, and S returns to now.
About
I like tech, arts, and order. I'm drawn to environments with a strong sense of vision. As a dreamer and (techno-)optimist, I enjoy my beliefs being stress-tested by reality. Trying not to live too fast — observing carefully, valuing every orbit around the Sun. Open to the right mission.
I'm currently deep in science fiction — Liu Cixin's Three-Body Problem trilogy quietly rearranged how I think about scale, time, science, and how fragile a civilisation can be.

Launcher
Jun 2026Reliability and reusability you almost take for granted now — reusing boosters and fairing halves many many times. Following since 2018. Hail the record booster B1067 with 35 launches.
Mission
Jul 2026The moment Jared (the current NASA Administrator!) climbed outside up the Dragon's forward docking port? I will always see the picture in my head. Proudly owning the original rubber mission patch!
Reading
Jul 2026Robert Anson Heinlein explaining his views on future Moon habitats, society and Earth's stance. For many more authors, this work of art must have been an inspiration.
