LAW OF UNIVERSAL GRAVITATION
1. Calculate the force of Earth's gravity on a spacecraft 12,800km (2 Earth radii) above the
Earth's surface if its mass is 1350 kg.
A. Explain the statement of John Wheeler below. Limit your answer into five (5) to
ten(10) sentences only. Write your answer on another sheet of paper.
“Space-time tells matter how to move; matter tells space-time how to curve.”
The questions about Rendezvous.
Describe the process of rendezvous between two spacecraft in Earth Orbit, describing one as the active chaser and the other as the passive destination spacecraft. Include the key elements that make rendezvous possible.
To illustrate one concept of rendezvous, consider two space craft in different orbits: One is in a higher circular orbit with an altitude of 400 km. The other in a lower elliptical orbit of 350 km by 385 km. The higher spacecraft is initially leading the lower spacecraft by a phase angle of 30 degrees.
How many orbits will the lower spacecraft need to make up the difference? To simplify the problem, you can use the average angular velocity as a constant in the problem.
