NASA is giving serious consideration to the concept of solar sailing. A solar sailcraft uses a large, low-mass sail and the energy and momentum of sunlight for propulsion. (a) Should the sail be absorbing or reflective? Why? (b) The total power output of the sun is 3.9 * 10^26 W. How large a sail is necessary to propel a 10,000 kg spacecraft against the gravitational force of the sun? Express your result in square kilometers. (c) Explain why your answer to part (b) is independent of the distance from the sun.
Two parallel disks of diameter D = 3 ft separatedby L = 2 ft are located directly on top of each other. Thedisks are separated by a radiation shield whose emissivity is0.15. Both disks are black and are maintained at temperaturesof 1200 R and 700 R, respectively. The environment that thedisks are in can be considered to be a blackbody at 540 R.Determine the net rate of radiation heat transfer through theshield under steady conditions.
To maximize the radiation pressure on the sails of a spacecraft using solar sailing, should the sheets be (a) very black to absorb as much sunlight as possible or (b) very shiny to reflect as much sunlight as possible?
