WHY IT WOULD BE SO HARD TO LIVE ON MARS 7 reasons the Red Planet is inhospitable to humans Esmsm O THERE ARE TWO KINDS OF RADIATION BOMBARDING HUMANS ON A LONG-TERM MARS MISSION: / Solar Galactic ( I energetic AND cosmic ( particles rays ) (SEPs) (GCRs) ) AND BOTH MEAN TROUBLE k ' THE 180-DAY TRIP TO \ MARS WOULD EXPOSE ASTRONAUTS TO 15 times THE ANNUAL RADIATION LIMIT FOR WORKERS IN A NUCLEAR POWER PLANT A 500-DAY STAY ON MARS WOULD ADD THE SAME DOSE AGAIN—AND THEN THERE'S STILL THE HOMEWARD TRIP THE AVERAGE TEMPERATURE ON EARTH IS A COMFORTABLE 57° F (14° C). THE AVERAGE ON MARS? A PARALYZING -81° F (-63° C). MARTIAN TEMPERATURES DO OCCASIONALLY REACH A SUMMERY 86° F (30° C), BUT THAT'S MOSTLY AT HIGH NOON AT THE EQUATOR, SO DON'T GET USED TO IT. EARTH’S ATMOSPHERE IS 100 TIMES DENSER THAN MARS’S AND IS COMPOSED OF 78% NITROGEN, 21% OXYGEN, AND 1% TRACE GASSES. MARS’S IS A POISONOUS 96% CARBON DIOXIDE AND THE REST TRACES OF ARGON, NITROGEN AND OTHER GASSES. THIS PART SHOULDN'T THIS PART SHOULDN’T BE TOO AWFUL MARTIAN GRAVITY IS ONLY 38% THAT OF EARTH'S, WHICH IS AT LEAST CLOSER TO WHAT WE KNOW THAN THE ZERO-G OF SPACE TRAVEL. BUTT m W BUILT FO W MANNER mi isn II BUT THE HUMAN BODY WAS BUILT FOR A FULL ONE-G, AND ALL MANNER OF SYSTEMS—SKELETAL, MUSCULAR, CARDIOVASCULAR— BEGIN TO FALL APART WITHOUT IT. f ONE OF THE BIGGEST REASONS WE WANT TO GO TO MARS IS TO SEARCH FOR SIGNS OF LIFE. BUT WHAT IF WE FOUND MICROBES ONLY TO LEARN THEY WERE DEADLY TO US? SPACE GERMS WERE ENOUGH OF A CONCERN IN THE APOLLO ERA THAT THE CREWS OF THE FIRST THREE MOON LANDINGS SPENT 21 DAYS IN MEDICAL QUARANTINE AFTER THEY RETURNED A THE INFRASTRUCTURE: MANY EXPLORATION PLANS CALL FOR ASTRONAUTS TO GROW CROPS IN MARTIAN GREENHOUSES. BUT HUMIDITY IS HARD TO CONTROL, AND THE PUNTS WOULD GIVE OFF SO MUCH OXYGEN THAT EXPLOSIONS MIGHT OCCUR i AND NONE OF THIS RECKONS WITH THE POSSIBILITY OF EQUIPMENT BREAKDOWNS. ONE MIT STUDY ESTIMATED THAT MARTIAN SETTLERS WOULD BEGIN DYING AS EARLY AS 68 DAYS AFTER ARRIVAL. THE ISOLATION AND CROWDING OF AN EIGHT-MONTH JOURNEY TO MARS WOULD BE A SEVERE MENTAL-HEALTH CHALLENGE—NOT TO MENTION THE 500 DAYS ON THE SURFACE AND ANOTHER EIGHT MONTHS BACK. THE PROBLEM OF WHAT'S KNOWN AS THE OVER-THE-HORIZON EFFECT. FOR SAILORS THAT MEANS THE LONELINESS THAT RESULTS WHEN THERE IS NO UND IN SIGHT; FOR MARS TRAVELERS IT WOULD MEAN A NIGHT SKY IN WHICH EARTH IS JUST ANOTHER POINT OF LIGHT. • INFOGRAPHIC BY TIME

Actually, NASA had probes on mars since the 70's - they were measure and took samples for long time. There're 2 reasons that it is a bit harder than we think: 1) The landing - to calculate perfect landing it is so difficult, Opportunity was almost crushed last time they have tried to land it - but it is still there and best part nothing has damaging its solar panels(it is there since 2004). 2) Growing food - growing edible food is very hard every where, that's why NASA want to send few kinds of agronomists.
But in the nest 15 years everything can change and we might have better technology.

Plot twist: mercury is actually much more habitable than mars. The gravity is nearly the same and it actually has an atmosphere that protects us. It would be harder to terraform, but a terraformed venus is much better than a terraformed mars.
