• maximize the room available to float
• SS2 - G effects to be minimized via reclined re-entry

30. FUTURE-SPACE COLONISATION
• The future existence of human races depends on space colonisation
• we affect the environment constantly
• At a point the earth will unfit for our survival so we have to leave our planet
• So the research on interstellar space , other habitable planets still goes on till we
find another planet to colonize
