OKAY, HERE'S HOW WE'RE GOING TO GET
THOSE SAMPLES BACK FROM MARS, STRAP IN!
THE SHIP THAT WILL TRAVEL TO MARS AND
RETURN TO EARTH WILL BE MADE UP OF
SECTIONS, BUILT ON EARTH, BUT ASSEMBLED
AND FUELED IN SPACE AT A LAGRANGE POINT,
IN A GEOSTATIONARY SOLAR ORBIT.
ONCE THE PARTS OF THE SHIP ARE ASSEMBLED
BY ROBOTS IN SPACE, THEY WILL BE LOADED
WITH THE FUEL THEY NEED FOR THE TRIP AND
THE RETURN. IN THIS WAY A LARGER SHIP
LOADED WITH FUEL CAN BE BUILT WITHOUT
THE PENALTIES EARTH'S GRAVITY WOULD
IMPOSE, ON ANY ATTEMPT TO LIFT AND
DEPART FROM EARTH'S SURFACE, THE
ENTIRE PACKAGE NEEDED TO LAND AND
RETURN FROM MARS.
