Astronauts gauge speed using physics tricks

Spaceships lack a direct mechanism for measuring their own velocity, a counterintuitive fact given their advanced technology. Instead, astronauts rely on clever applications of physics principles to determine their speed. These methods involve indirect calculations and observations, leveraging fundamental laws of motion and potentially external reference points. The article delves into these ingenious techniques, explaining how the challenges of space travel necessitate creative solutions for fundamental measurements like speed, ensuring mission safety and accuracy.
