Spaceship Type: Triangle Capsule

• Rendezvous
  Earth and Mars are in heliocentric orbits. Launch a spacecraft from Earth to Mars. While using the least ΔV, approach within pixels of Mars, % of Mars' speed, and ° of Mars' velocity vector.
• Launch
  Launch from the Sun into orbit. Attain an eccentricity of ±0.05 or a period of ±10 days. The spaceship will start out with a large thrust to launch. You'll need to increase and decrease the thrust using the A and S keys.
