Mars is red due to iron oxide in its soil and has a thin atmosphere composed primarily of carbon dioxide. Only one third of spacecraft sent to Mars have been successful. Going to Mars would be an important part of the space program, but it is also very dangerous and expensive, costing around $20 million and requiring two years to travel there and back. Some problems with human missions to Mars include exposure to radiation, and limited oxygen and food on the long trip.

2. MARS IS RED BECAUSE OF IRON OXIDE

3. IT HAS A VERY THIN ATMOSPHERE, MADE MOSTLY OF CARBON DIOXIDE

4. ONLY ONE THIRD OF THE SPACECRAFTS SENT TO MARS HAVE BEEN SUCCESSFUL

5. GOING TO MARS WOULD BE AN IMPORTANT PART OF THE SPACE PROGRAM

7. IT WOULD BE VERY DANGEROUS AND EXPENSIVE ...

8. … AND IT WOULD COST ABOUT 20 MILLION DOLLARS AND TAKE TWO YEARS TO GO THERE AND COME BACK

9. IT MIGHT BE POSSIBLE FOR HUMANS TO LIVE ON MARS FOR A SHORT PERIOD OF TIME

11. THE FIRST MANNED MISSION COULD BE “ALREADY” THIS CENTURY

12. THERE ARE SOME PROBLEMS WITH GOING TO MARS

13. ASTRONAUTS GET EXPOSED TO A LOT OF DANGEROUS RADIATION IN SPACE

14. OXYGEN OR FOOD COULD RUN OUT ON THE TWO-YEAR TRIP

15. THE LOW GRAVITY ON MARS MIGHT ALSO BE HARMFUL TO HUMANS
