New Spaceship design a little bit different

Ram Tripathi of NASA's Langley Research Center is proposing that rockets are not the best way to send a man to Mars. In the alternative design the spaceship would look like "a grapefruit spiked with cherries on sticks." The spaceship would be designed this way to protect from galactic cosmic rays which can cause cancer. The idea is that the spherical shape that the ship is made into would help deflect cosmic rays away from the central habit of the astronauts.
