Which effect occurs upon gravity probe-A achieving apoapsis?

A)Gravitational time dilation decreases slightly
B)Orbital velocity increases temporarily
C)Spacecraft temperature drops precipitously
D)Communications bandwidth reaches maximum throughput

💡 Explanation

Gravitational time dilation decreases because equivalent potential increases during apoapsis via the equivalence principle; therefore observed time slows less relative to Earth rather than an increase in orbital velocity, which drops when radial separation increases.
