We want to design and build a solar sail that will carry us from Earth to the Moon in a time of 3.0 weeks. Assuming this is a simplified set up, where we are using the sun’s radiation to travel directly away from it, a total distance of 385,000 km, in a time of 3.0 weeks, starting from rest.

a) What is the necessary acceleration (think back to kinematics)?

b) What area of solar sail will the craft need, assuming the sail and craft together have a mass of around 10,000 kg, and that the sail is reflective? The solar intensity is 1350 W/m2.

1. The closest star, other than the Sun, to us is at about 4 light years. To escape from the solar system a space craft has to travel at a minimum of 42 km per second. That is not really fast enough, because as the Sun's gravity keeps tugging on it, while it would escape, it would slow down in velocity as time goes on and not be going very fast once it is far from the Sun. But let's...

Problem Solving: LightSail 2 LightSail 2 was a satellite that was designed to use solar radiation to change its altitude as it circled Earth. The spacecraft had a mass of 5.0kg. It was originally launched by a rocket with its sail closed, and established an orbit at an altitude of 720 km above Earth’s surface. Then it deployed its sail, which had an area of 32m2 . Assume the sail is completely reflective. 1) After a full month of “½...
