|+ ''' Luna's and Mars' Characteristics '''
! Quality !! Luna !! Mars
|-
| ''Atmosphere'' || vacuum || 0.1 psi Carbondioxide
|-
| Advantages || no barrier to high speed travel __ allows use of structural materials incompatible with oxygen and water __ no barier to observations __ no wind born dust __ no requirement for structures to withstand weather || convenient source of carbon & oxygen __ allows use of aerobraking and other aerodynamic effects __ protects against staticly levitated dust and most meteors
|-
| Disadvantages || leads to dewetting of lubricated surfaces __ can not be breathed by people or internal combustion engines __ requires space suit protection of people __ requires pressure chambers for industrial processing involving most liquids __ requires pressure chambers for industrial collection of gas __ no protection against micrometeoroids or staticly levitated dust || can not be breathed by people or internal combustion engines __ requires about the same suit protection of people as a vacuum __ requires pressure chambers for industrial processing involving most liquids __ blows dust storms __ interferes with observations __ requires structural considerations to deal with weather __ does not permit electrical acceleration to orbital velocity
|-
| ''Gravity'' || 1.62 meters per second squared || 3.66 meters per second squared
|-
| Advantages || lower loading on structures to resist gravity than on Mars __ 04.7% of energy needed to orbit Earth can get to lunar orbit || lower loading on structures to resist gravity than on Earth __ 20% of energy needed to orbit Earth can get to Mars orbit
|-
| Disadvantages || lunar gravity may be insufficient to maintain human health __ low gravity causes problems with low traction for construction work || Mars gravity may be insufficient to maintain human health __ low gravity causes problems with low traction for construction work
|-
| Round Trip Communications Delay || 2.56 seconds || about 23 minutes average, about 540 times the delay for Luna
