Two satellites are in circular equatorial orbits of different altitudes. Satellite A is in a geosynchronous orbit (one with the sameperiod as the earth's rotation so that it "hovers" over the same spot on the equator). Satellite B has an orbit of radius rg = 26000 km.

A spaceship is traveling through deep space towards a space station and needs to make a course correction to go around a nebula. The captain orders the ship to travel 2.7 x 106 kilometers before turning 70° and traveling 2.3 x 106 kilometers before assuming the path towards the space station. If the captain had not ordered a course correction, what would have been the magnitude (in kilometers) and direction (in degrees counterclockwise from the +x-axis) of the path of the spaceship if it had instead traveled directly through the nebula?
