NOON UNO HIGH-MOBILITY MARS EXPLORATION SYSTEM DANIEL MCCAFFERY JEFF ROBINSON KYLE SMITH JASON TANG BRAD THOMPSON
2
Studying and exploring Mars is an essential part on the road to putting man on the planet The design makes it an outstanding high-mobility vehicle used for Mars exploration Very low development, construction, and operation cost IntroductionIntroduction
3
Our Mission Leave GTO and travel to Mars Separate from spacecraft and begin flight Cruise 35 km at 183 m/s (best range) Loiter at 143 m/s for 45 minutes (best endurance) Descend at 7.9 m/s (sink rate) in Gusev Crater

Mars Spacecraft
9
Launch Vehicle Selection Ariane 4 $60 million launch cost 3465 kg boost capability to GTO 4 meter diameter fairing
10
Spacecraft Propulsion TR-312-100YN Liquid Bi-propellant* I sp = 330 sec Thrust = 556 N Weight = 6.03 kg * Manufactured by TRW
11
AstrodynamicsAstrodynamics 185 km altitude about Earth at perigee 35,786 km altitude about Earth at apogee At perigee, velocity = 10.25 km/s 1 st burn, velocity increases by 1.159 km/s v at end of transfer orbit to match Mars’ velocity 2 nd burn, velocity increases by 2.65 km/s v required to be captured by Mars’ gravity and enter circular orbit at an altitude of 500 km 3 rd burn, velocity decreases by 1.373 km/s For atmospheric entry: 4 th burn, velocity decreases by 0.0958 km/s
12
EntryEntry After re-entry into atmosphere, first parachute deploys to reorient spacecraft and takes away heat shield Main parachute deploys from blunt end of shell and pulls it away Parachute deploys from the aft end of aircraft and separates it from rest of capsule Aircraft releases parachute and flies down to cruise altitude

Mars Aircraft
14
Aircraft Description Take off mass – 84.5 kg Wing span – 3.67 m Fuselage Length – 3.02 m Diameter – 0.25 m Low, swept, tapered wing Canards Skids
15
AerodynamicsAerodynamics NACA 4415 airfoil Wings - 3 incidence Main Wings - 20 sweep Canards – 22.5 sweep Drag Cruise – 11.88 N Loiter – 5.82 N
16
Aircraft Propulsion Aircraft engine - nitrogen tetroxide (NTO) / monomethyl hydrazine (MMH) I sp = 290 sec Max Thrust = 22 N Mass = 0.7 kg
17
Carpet Plot Constraints Sink rate < 10 m/s M < 0.8 Cruise velocity > 160 m/s Minimize take off mass without violating constraints
