Question

A small asteroid of mass 2.6 x 10^9 kg is discovered traveling at a speed of 18 km/s on a direct heading for a starbase that is in deep space outside the solar system. The starbase inhabitants want to deflect it by hitting it with a remote-controlled spaceship. The spaceship has an empty mass of 25,000 kg and a top speed of 85 km/s when its fuel is exhausted. The asteroid has to be deflected so that by the time it reaches the starbase, its center is 1800 m away from its original path. What is the minimum time before the asteroid's projected impact that the spaceship must reach the asteroid?
