Satellite imagery and space travel provide direct visual confirmation of Earth's spherical shape.

Since the dawn of the space age, countless photographs and videos taken by satellites, probes, and human astronauts have unequivocally shown Earth as a sphere. From the iconic 'Blue Marble' photograph taken by Apollo 17 to live feeds from the International Space Station, the visual evidence is overwhelming and continuous. These images are not merely artistic renditions but raw data captured by advanced optical systems, providing irrefutable, direct observation of our planet's curvature. Furthermore, the principles of orbital mechanics, which govern satellite trajectories, are only viable if Earth is a massive, rotating sphere.
