The acceleration of gravity is inversely proportional to the square of
the distance from the Earth's center. So out where the astronaut is,
the value of gravity will be
(9.81 m/s²) · (4230/6380)² = about 4.31 m/s² .
No matter where she is, her weight is always
(mass) x (gravity in that place)
= (82 kg) x (4.31 m/s²) = 353.6 Newtons
