The solar wind is made up of ions, mostly protons, flowing out from the Sun at about 400 km/s. Near Earth, each cubic kilometer of interplanetary space contains, on average, 6 × 1015 solar-wind ions.
How many moles of ions are in a cubic kilometer of near-Earth
space?

The semimajor axis of Mars orbit is about 1.52 astronomical units (au), where an au is the Earth's average distance from the Sun, meaning the semimajor axis of Earth's orbit is 1 au. To go from Earth to Mars and use the least energy from rocket fuel, the orbit has a semimajor axis of 1.26 au and an eccentricity of about 0.21. Starting at Earth's orbit, to follow this path we give the spacecraft an orbital velocity of 40 km/s. ...

Constants In this example we will investigate the viability of using radiation pressure to propel a spacecraft. Suppose a spacecraft with a mass of 2.50 x 10 kg has a solar sail made of perfectly reflective aluminized film with an area of 2.59 x 106 m2 (about 1 square mile). If the spacecraft is launched into earth orbit and then deploys its sail at right angles to the sunlight, what is the acceleration due to sunlight? (At the earth's distance...
