    Two identical singe waves 90 degrees out of phase

    Is the output equal in amplitude to the original wave?

    How Many Orbits Does a Solar Sail Need to Reach the Moon?

    I could certainly just say that I haven't taken black outs into account.

    How Many Orbits Does a Solar Sail Need to Reach the Moon?

    A solar sail is orbitting the earth. It needs to get to the moon by increasing its orbit energy through solar propulsion. How many orbits will it need to make and how long will it this take? Considering it starts in a Geostationary Transfer Orbit and has an acceleration of 0.5 mm/sec2.

    Why doesn't the orbit increase in radius?

    http://www.go.ednet.ns.ca/~larry/orbits/kepler.html v2 = GM/a so if V increases a (the orbital radius) must decrease. I'm quite confused

    How is the formula for calculating solar pressure derived?

    Can anyone explain how the following formula is derived: Force (F) = 2(P x A)/c P=power A= Area

    Why doesn't the orbit increase in radius?

    The following site shows that when a sail is orientated so that it faces away from the sun, the net force is pushing outwards from the sun and is also opposing the orbit. http://solarsail.jpl.nasa.gov/introduction/how-sails-work.html It makes sense that the craft should slow down, but why...
