WHAT CAN ASTRONAUTS DISCOVER ON MARS WHEN THEY LAND IN THE 2030S?

THERE ARE NOW COUNTLESS SATELLITES AND ALSO ROVERS FROM EXTRA AGENCIES THAT ARE  ABLE-TO LAUNCH OBJECTS AND OTHER SPACE JUNK WITHOUT SUCH EXPLOSION WHEN THEY ARE ESCAPING THE ATMOSPHERE PRESSRURE OF EARTH, AND ARE USING THE EARTHS GRAVITATIONAL PULL TOE SCAPE FROM THE ORBIT, OF THE EARTH, AND THEN NOW, HUMANITY HAVE BEEEN SUCCESSFULLY OVER THE COURSE YEARS, FROM 2001-2018, BEEN EXPLORING THE RED PLANET AND NOW THEY HAVE EVEN LANDED ROVERTS FOR 5 YEARS STARTING FROM 2012-2018, AND DURING THIS ROUGH TIMELINE OF ROBOTIC EXPLORATION, THEY HAVE STUDIED  THE GEOLOGY, THE CLIMATE,THE WEATHER, AND EVEN THE DUST  GROUND DOWN BELOW, AND AEVEN ATMOSPHERE OF MARS AND ALSO MUCH MORE, NASA NOW JUST PLANS TO FIND SOME OTHER LITTLE WATER BODIES, AT THE SOUTH POLE AND FINALLY MATHEMATICALLY ESTIMATE IF THERE COULD BE SOME ANOTHER PERFECT TIMELINE FOR THESE ASTRONAUTS TO LAND THERE FIRST, THIS PLAENT IS THOUGHT  ONCE TO HAD OCEAN AND THIS PRESENT TIME HAVE SOME  OCEANIC DEBRIS, AMONG THEM...

• THEY COULD FIND SOME ANCIENT LITTLE LAKES.
• THEY COULD FIND DUSTED SURFACE
• THEY COULD FIND RED DESRT, BECUSE FROM THAT TIME, THE VAST TEMPERATURES GREATLY IMPACTED THE SURFACE
• SUITABLE  FLAT LANDSCAPE FOR DEVELOPING THE SELF-SUSTAINING FORMATED COLONY, IN THAT MARTIAN REGION.....
