2. AAE 450 – Spacecraft Design Solar Power  Reliable and proven source of power  Mass scales approximately linearly with power Description Power near Earth (kW) Power near Mars (35% Earth) (kW) Mass (kg) Volume (m^3) Array Area (m^2) ISS PV Module 289.83710 750 Mars DRM 3010.53842.54.417719 Mars DRM 51.810481.289203.5 ISS scaled 802811000 2142.9 Mars DRM scaled 14.352500~3.68581.4

3. AAE 450 – Spacecraft Design Autonomous Docking  Can we dock autonomously in Martian orbit?  Large communication Delay between Earth & Mars  Russian Soyuz and Progress vehicles have shown autonomous docking capability with the ISS  Is autonomous docking in Earth orbit without a comm. link to the ground proof of capability of autonomous Martian docking?  Issues: Complexity and reliability vs. cost (mass) savings  Soyuz has had to use manual override once (out of 14)
