Four Phases of LOW Mission:
1.) Landing
2.) Traveling
3.) Experimentation
4.) End of Mission

7. Landing-Unloading Relevant Subsystems Power Communications Payload

-Launch Date – All material req’d for construction of LETS shall not have long lead times and be up-to-date (including technology). Final des. constr. well b4 launch date for testing and simulation
-Mass – total: kg, prop sys dry: 64.6 kg. Left with kg to use. Significant bc most of mass will be used for scientific equipment.
-SMD/ESMD ratio – must be 2:1 ratio. SMD means scientific exploration to understand solar system; ESMD means establish sustained human/robotic presence in space. LETS primary focus is science and less on exploration sys.
-Landing – landing with +/- 100m 3 sigma precision and at 12 deg. Talk about jettisoning prop sys away from lander prior to landing and troubles it creates. Talk about landing on 12 deg slope – appropriate structural capabilities req’d to accomplish this (landing on wheels as opposed to crush pads or legs)
- Mobility – sampling sites 500m apart and samples taken from perm. dark and lighted terrain, need reliable mobility. Lander on wheels allows for entire sci. payload to travel with lander simul. from site to site by use of an RTG.

8. Traveling Relevant Subsystems Power Mobility Thermal GN&C
Runs entirely off of solar arrays and batteries
Use of nuclear power was avoided
Nuclear power prevents 2012 launch date
Nuclear power is scarce throughout the space program

11. How LOW meets goals? Maximize Scientific Payload
LOW has the potential to visit extra sites
LOW can perform more in-dept experiments
Minimize Single Point Failure
Comprised entirely of TRL 9 technology
Conservative ConOps Schedule
No Lag time in data communication
