3. Astronauts on Mars need to escape the planet and rendezvous with an orbiting ship that will take them back to Earth due to a storm. The crew and crew capsule have a combined mass of 4500 kilograms and need to make an escape velocity of 5000m/s to reach the ship and the engines develop an Isp of 410 seconds. The booster section of the escape vehicle is 5% structural mass for the given amount of fuel in the vehicle. How much fuel does the escape rocket need and how much thrust does it need to take off the launch pad with the equivalent acceleration of 1.5 earth gravities, consider the impact of Martian gravity on the rocket's acceleration.
