  1. Mission to Mars ENGR 103 Team FFF Prof. Choi

  2. Launch Dates and Mission Itinerary

  3. General Method of Travel • Two Ships • Mars Mission Supply 1 • Hohmann Transfer • Spaceship Ram • Assembly and launch in Space

  4. MMS1 and the Hohmann Transfer • Mars Mission Supply 1 (MMS1) • Fuel- 7000kg • Batteries- 5000kg • Supplies • Food- 700kg • Tools for Martian Exploration- 100kg • Landing Craft- 14000kg • Mars Buggy- 210kg • Total- 27010kg

  5. Launch Dates • Mars Closest to Earth • May 22, 2016 • July 27, 2018 • Launch of MMS1- November 16, 2017 • Launch of Spaceship Ram- June 17, 2018 • Both crafts enter Martian Orbit- July 27, 2018

  6. Martian Day 0 • Entrance into Mars orbit • Rendezvous of Spaceship Ram with MMS1

  7. Martian Day 1 • Docking with MMS1 • Preparation for landing upon Martian Surface

  8. Martian Day 2 Mars Expedition Orbiting Vessels • Battery swap • Begin hydrogen refueling process • Landing upon Martian Surface

  9. Martian Day 3 Mars Expedition Orbiting Vessels • Deuterium Helium 3 refueling • Transfer of supplies payload • Exploration • Collection of Samples

  10. Martian Day 4 Mars Expedition Orbiting Vessels • Finish hydrogen and DHe3 refueling • Flight Preparations • Exploration • Further Sampling

  11. Martian Day 5 Mars Expedition Orbiting Vessels • Finish Flight Preparations • Disconnect from MMS1 • Return Trip • Extraction of Astronauts • Rejoin with Spaceship Ram

  12. Structure Living quarters modeled after the Mir living module Standard life support Exercise equipment Solar panels Experimental equipment Docking Port Food, Water Waste Facility

  13. Sub-structure • Fusion device • 6” Titanium tubes • Capacitor bank • Hydrogen tank • Pellet factory • Laser • Pusher Plate

  14. Safety Radiation large concern Duration of human space mission is 90 days Secondary radiation Galactic cosmic radiation Solar energetic particles Interact with space structures Generally ignored in space architecture Neutrons emitted from fusion reaction Use Deuterium-Helium3 Prolonged exposure includes radiogenic cancers • Boron nitride nanotubes • Low atomic number atoms • Can be processed and hydrogenated

  15. Fuel Source ²D + ³He → 4-He (3.6 MeV) + p+ (14.7 MeV) 18.3 MeV Total

  16. Fuel Source • 1263.55 kg ²D fuel • 1895.33 kg ³He • Total fuel mass: 3158.88 kg

  17. Fuel Source

  18. Fast Ignition

  19. Fast Ignition Magnetic Confinement Fusion Magnetic confinement is impractical Torus (Tokamak) - “Their great size and mass render them unappealing for space propulsion, where lightweight is paramount." Primary Problem – Difficult to sustain the fusion reaction while ‘leaking’ out plasma Mirror - “The dearth of experimental data on their operation and indeed their engineering feasibility render serious engineering assessment difficult" Torus Mirror

  20. Fast Ignition Inertial Confinement Fusion Avoids magnetic confinement’s main problem Existing plasma not required Constant flow of fuel pellets makes new reactions Complex magnetic fields not needed Simple Pusher Plate Directs charged ions backwards

  21. Fast Ignition Specifics: Tradition ICF’s still have problems National Ignition Facility reactor contains 192 lasers delivering a total of 500 terawatts of power Fast Ignition Concentrates laser energy on single point Reduces amount of lasers, energy required, and design complexity

  22. Fuel and Energy • Chosen type of fuel D- He3 • 20ps pulses • 100kj energy requirement per pulse • Combined fuel and energy calculations to find totals

  23. Mission Totals • Burn time of 6 hours to reduce G load • Laser firing every 20ps • 5.00 x 10^15 watts • 1.08 x 10^20 Joules • Power of NIF is 1.25x10^15 watts

  24. Energy Source • Method of storing energy • Problems with conventional energy storage • Mass • Size • Loss of voltage • Inefficient • Need for plausible source of power for trip

  25. Graphene • High capacity energy storage device • Energy density 10-20 times greater than conventional • Thin layers create huge surface areas to store energy on. • Create a “black box” to store the initial power required

  26. Crew for our mission

  27. Catherine Coleman • Catherine Coleman is a current NASA astronaut • She was a crew member of the expedition 27 to ISS. • While on expedition 27, she spent 159 days in space aboard the international space station.

  28. Sergei Avdeyev • Sergei Avdeyev is a Russian engineer and cosmonaut. • He at one point held record for cumulative time spent in space, with 747.59 days in Earth orbit accumulated through three tours of duty aboard the Mir space station. • The longest time he spent in space was during the Soyuz TM-28 & Soyuz TM-29, in which he stayed 379 days aboard the Mir space station.

  29. Gennady Padalka • Gennady Padalka is a Russian Air Force Officer and an RSA cosmonaut. • Gennady, served as the commander of Mir Expedition 26 launched on August 13, 1998. • He accumulated 198 days and 16 hours of space travel during the Soyuz TM- 28 mission.
