Journey to Mars

10 241 feet Current weight 612,000 lbs 925,000 lbs when completed
Journey to Mars

11 We’ve Been to the Moon and scheduled to return by 2018
Journey to Mars

12 Then it will be on to Mars
Why is Mars so fascinating? Journey to Mars

13 1877 Giovanni Schiaparelli
Journey to Mars

14 First Mages of Mars Mariner 4 Spacecraft 1965
Journey to Mars

15 Mariner 9 —1971 Orbited Mars Imaged entire planet
Possible signs of water erosion Journey to Mars

16 Viking 1976 — First Landing No signs of life
Journey to Mars

17 What is Mars Like? Diameter 3,400 KM (4,200 miles)
Atmospheric pressure .9 kPa (.2” hg) Atmospheric composition 95% CO2 Journey to Mars

18 Water! Temperature min mean max −122 °F −50 °F +23 °F
− 87 °C −46 °C −5 °C −122 °F −50 °F °F Water! Journey to Mars

19 How can we get there? Journey to Mars

20 Martian Orbit Compared to Earth
93 million miles 365 Day Period 66,000 mph Earth Orbit Mars Orbit Sun Earth’s Rotation Earth 142 million miles 687 Day Period 53,000 mph Mars Journey to Mars

21 Hohmann Transfer Orbit
to to Mars Mars Mars at Opposition 1 2 3 5 7 6 4 6 7 Earth Orbit 4 Mars Orbit Sun 9 2 Earth’s Rotation 11 Mars 1 Mars Mars at Conjunction Every 26 months Earth Typical transit time 8 months Journey to Mars

22 Propulsion Requirements
5. Land (-10,000) Mars 4. Mars Orbit (-2,000) 6. Surface Exploration 7. Mars orbit (+10,000 mph) 8. TransEarth Injection (-7,000 mph) Mars Orbit Sun 9. Cruise—no propulsion 3. Cruise—no propulsion 10. Enter Earth orbit (-7,000 mph) Earth Orbit 11. Renter Earth’s atmosphere (-18,000 mph) Earth 1. Earth orbit (+18,000 mph) 2. TransMars Injection (+7,000 mph) Journey to Mars

23 How long is a Mars Mission?
Outbound Journey over 200,000,000 miles 3 years round trip most likely scenario Radio communications to Earth takes as long as 20 minutes Journey to Mars

24 Phoenix Critical Landing Phase
77 miles 12,750 mph 42,000’ 1,125 mph 639 mph 2,500’ 1,900’ 3.5 mph Journey to Mars

25 Journey to Mars

26 What will it take for Humans to travel to Mars?
Mars Landing Habitation & Exploration Return Reentry to Earth’s Atmosphere Propulsion Spacecraft Systems Electrical Power Life support for crew Consumables Effect of weightlessness Shielding from radiation Journey to Mars

27 Taking it all With You Weight 700 tons (1.4 million pounds)
To Earth orbit equal to 28 Shuttle flights 8 ARES V flights Journey to Mars

28 Forming Teams Crew Selection Propulsion Spacecraft Electrical Power
Life support for crew Consumables Effect of weightlessness Shielding from radiation Mars Landing Habitation & Exploration Journey to Mars

29 Crew Selection How many persons would comprise your crew?
What would be their areas of expertise? How would you choose them? Journey to Mars

30 Propulsion What type of propulsion would you use to make the trip:
Chemical (traditional rocket engines) Nuclear reactor rocket engines Solar sails Ion Electric Why did you choose that system? Journey to Mars

31 Life Support How much weight for a three year mission if:
O2 (6 lbs/day) per Crewmember Water (130 vs 3 gals/day) per Crewmember Food (2 lbs/day) per Crewmember What consumables might you be able to get form the Martian environment? How would you handle the weightlessness problem? Journey to Mars

32 Spacecraft Electrical Power
How will you provide for the electrical needs of the various onboard systems. Solar cells Fuel cells Nuclear reactor Radioisotopic Thermal Generators Why did you choose that system? Journey to Mars

33 Landing on Mars What method or combination of methods might you use:
Aerobraking Parachute Retro-rocket Airbag Why did you choose that method? Journey to Mars

34 Habitation & Exploration
How would you house the crew? How would you provide electrical power? What method of ground transport? What three scientific experiments might you perform? Will we find LIFE? Journey to Mars

35 What will we Find? Journey to Mars

36 Break Work in your teams to answer the questions posed to your team for the next 30 minutes. Appoint a spokesperson to present your solutions to the problems. Journey to Mars

37 How Soon Mars? Basic technology is available
Could be launched in 10 years Estimated cost $300 Billion Congress does not consider cost and risk acceptable Current timetable 2037 Journey to Mars

38 NASA Budget Journey to Mars

39 Are you ready to go? Journey to Mars

40 Questions? Journey to Mars

41 Mars Phoenix Lander 11/27/2007 Journey to Mars
