The discussion focuses on calculating the gravitational force acting on a 70-kg astronaut located 2.0 Earth radii from the center of Earth. The gravitational force can be determined using Newton's law of universal gravitation, specifically the formula F = G(m1*m2)/r^2, where G is the gravitational constant, m1 is the mass of the Earth, m2 is the mass of the astronaut, and r is the distance from the center of the Earth. At 2.0 Earth radii, the gravitational force is significantly reduced compared to the force experienced at the Earth's surface.
