  6. So what Kind of Launch Vehicle do we Need? • Mission Architecture? • Typical Lunar Missions • 10 – 45 metric tons translunar(40 ~120 metric tons to LEO) • Typical Mars Mission Concepts • 100 metric tons to LEO with staging • Can we use a smaller launch vehicle? (SsTO) John Conklin - Stanford University - E235a -6- 3/9/04

  7.

  10. The Energiya • Successor to N1 moon rocket • 2 Stage Launch Vehicle(Stanford IMM requires additional third stage) • Cryogenic core + 4 LO2/kerosene strap on boosters (Zenit) • Length – 193 ft (59 m)N1-L3 stood 345 ft (105 m) • Payload • 100 Tons to LEO • 18 Tons to GEO • 32 Tons translunar • 28 Tons Venus/Mars • Track Record • May 15,1987, mock-up of Polyus spacecraft • Nov. 15, 1988, Buran Orbiter John Conklin - Stanford University - E235a -10- 3/9/04

  11. Viability of EnergiyaDoes the Energiya still “exist”? • Only two Launches • Last launch was 16 years ago • May 2002, Baikonur Cosmodrome Roof Collapse left only full-scale test model of Buran Shuttle and Energiya carrier rocket buried • Energiya cited as launch vehicle for RKK Energiya’s newly disclosed Mars mission concept Photo of Buran and Energiya just prior to collapse – Space.com John Conklin - Stanford University - E235a -11- 3/9/04

  12. Russian Mars Mission Concept (SPK RKK Energiya) • Unveiled on Energiya’s website shortly after NASA’s new space policy was announced • Elements delivered to LEO, then assembled into a single vehicle • Solar electric propulsion • 3 months to leave earth orbit • 8 month transit to mars • 1 month to enter Mars orbit • 1 month on Mars surface • 6 person crew • Reusable vehicle • 6 – 7 Energiya Launches required John Conklin - Stanford University - E235a -12- 3/9/04

  13. Shuttle Derivative(The Shuttle-C) • Shuttle-C concept devised in the mid 1980s • NASA Marshall design for replacement of shuttle orbiter with recoverable main engine pod • Uses Space Shuttle Solid Rocket Boosters and External Fuel Tank • Payload • 77 metric tons to LEO • 8.7 m diam / 56 m length(comparable to Energiya) • Cost per Launch? • Less than the STS(big deal) • $120 - $550 mil USD?

Korolev • Current configuration introduced in 1966 • 3 – 4 Stages • Kerosene fueled • Manned/Unmanned • LEO – Mars escape trajectory • Soyuz is the Most prolific launch vehicle ever • Over ????? launches since the 1957 launch of sputnik • Safety Rating • Over 70 manned launches with %??? safety rating since 1961 launch of Yuri Gagarin • Equipped with launch escape tower • Generally preferred by U.S. astronauts over Space Shuttle • Assembly line production • Currently in uninterrupted production of 10-15 launch vehicles per year • In early 1980s reached peak production rate of 60 vehicles per year John Conklin - Stanford University - E235a -14- 3/9/04

Korolev • Current configuration introduced in 1966 • 3 – 4 Stages • Kerosene fueled • Manned/Unmanned • LEO – Mars escape trajectory • Soyuz is the Most prolific launch vehicle ever • Over 1,680 launches since the 1957 launch of sputnik • Safety Rating • Over 70 manned launches with %100 safety rating since 1961 launch of Yuri Gagarin • Equipped with launch escape tower • Generally preferred by U.S. astronauts over Space Shuttle • Assembly line production • Currently in uninterrupted production of 10-15 launch vehicles per year • In early 1980s reached peak production rate of 60 vehicles per year John Conklin - Stanford University - E235a -14- 3/9/04

  17. The ChangZheng 2F(Long March) • First ChangZheng rocket launched in 1960 with Russian aid [13] • Man rated version of China’s Long March family of launch vehicles • October 15, 2003 the Long March 2F Launched Shenxhou-5 spacecraft carrying the first Chinese “Taikonaut” into Low Earth orbit • 5 Successful launches to date • Equipped with launch escape tower • Shenxhou autonomous orbital module allows for the possibility of future space station construction and ISS docking [13] • Major Contribution: Lessons learned [13] Escutia, Paul, “China’s Space Program: Growing International Connections”, Fall 2003 EDGE John Conklin - Stanford University - E235a -15- 3/9/04

  18. International Spaceports • Can launch larger payloads into equatorial orbits from locations closer to the Earth’s equator. • Other sites more ideal for polar orbits • e.g., EADS-Rosaviakosmos agreement to launch Soyuz at Kourou John Conklin - Stanford University - E235a -16- 3/9/04

  19. ISS / Moon and Mars Manned Vehicle Construction and Architecture • Vehicle staging and construction in LEO • Using the ISS as a spacecraft factory • RKK Energiya Mars mission test plan includes test vehicles constructed at ISS • Advantage: Separation of Cargo and Crew John Conklin - Stanford University - E235a -17- 3/9/04

  20. Separation of Cargo and Crew • Concept • Use “energetic” HLLVs to loft heavy cargo/vehicles • Use lighter and more reliable launch vehicles for crew transfer • Opposite of Apollo/STS/Buran/SsTO concepts • Consistently used by Russia to construct and man space stations • Reduces cost and Increases Safety • Limits Payload returned to Earth • NASA Leaning toward this approach in the future(phase out STS in favor of CEV)? = 2 + 2 John Conklin - Stanford University - E235a -18- 3/9/04

  21. Brief History of Russian Space Station Construction/Missions *Failed to open hatch between Salyut and Soyuz**First manned space station mission. Soyuz capsule depressurized during reentry***Failed to dock with space station (Soyuz 23 – control system failure, landing in Tengiz Lake)****Sept 1983, Soyuz T exploded on Launch pad, but Escape system saved the crew John Conklin - Stanford University - E235a -19- 3/9/04

  22. Conclusions • International cooperation is crucial to success of Lunar, Mars Missions and continued ISS operations • Launch Vehicles • Launch Sites • Use the right launch vehicle for the job • 40 – 120 metric ton to LEO LV for large vehicle components • Reliable, smaller LV for crew transfer John Conklin - Stanford University - E235a -20- 3/9/04
