Mô tả: Everything seems difficult in orbit: A spacecraft that is orbiting the Earth is not beyond the Earth's gravity (in fact, the Earth's gravity holds it in orbit). Instead, they are in a state of perpetual free-fall around the Earth that leads to microgravity. Thank you to the CNES, the french space studies agency, for these comic and pedagogical video extracts.
