Question: What is the expected number of impacts on the space shuttle during a two week mission at a 400 km circular orbit altitude and 51.6 degree inclination by debris particle greater than 4mm in size? For particles greater than 1 cm? Assume the platform to be 367 m2 to be revealing target.
Please show me how work it out above question.
