how could scientists find out if micro organisms lived on mars long ago?

M.B., NC | (none)
To answer some of these Mars questions: Q: Why does Mars have a longer year than earth? A: Basically because it is farther from the sun. Q: How many moons does Mars have? A: 2 known moons: Phobos and Deimos Q: Where does mars get its color? A: The iron/rust in its surface causes the red color. Q:What rovers does Mars have? A: NASA has sent Spirit, Opprotunity, and Curiosity. Q: Does Mars have life? A: Some scientists believe that there could have once been , or still could be life on Mars. They are searching for microbes under the surface of Mars, because scientists call those the building blocks of life as we know it. That is one reason NASA sent Curiosity to Mars (landed Aug. 6th 2012!), to search for the microbes, by searching for water using infrared cameras. There is actually an experiment posted with the infrared cameras on the DFTV website. Q: Does mars have a sun? A: Many people have posted this question!! YES! Mars has 1 sun...our Sun!! It is in our solar (sun) system, therefore it revolves around the same sun that earth does!! The Sun is the only sun in our solar system, unlike some binary solar systems that exoplanets are part of. Q: How many satellites does mars have? A: Mars has three artificial and two natural satellites: The Odyssey (Oct. 2001) The Mars Reconnaissance Orbiter (MRO) (March 2006) The Mars Express (not a NASA orbiter) (Dec. 2003) Q: Have any astronauts been to Mars? A: No, astronauts nor cosmonauts nor any other space explorers have been to Mars. However, NASA is currently creating the Orion Multi-Purpose Crew Vehicle, which is planned to have an unmanned test flight in 2014, return humans to the moon by 2020, and fly humans (ME) to Mars by 2040. Q: Could humans live on Mars? A: Currently with the technology available today, no humans could live on mars long-term, however with hydroponics stations, and a good design of living/storage space, humans would spend longer times on Mars. Similar to the "colonies" that NASA is designing for the moon, something like that could support life on Mars.

Daniela, FL | (none)
Hi Jennifer. We can not live on Mars because there is too much carbon dioxide and there are no trees clean the air only rocks,volcanos, mountains,and deserts. Mars is half the size of Earth. However it weigh 100 pounds, a day in Mars would be 24 hours and 38 minutes.Many people call Mars the "Red Planet."

Isiah, NY | (none)
I don't know why some people think that there are life on Mars.There's no life on Mars.Just only red rocks.And it takes 600+ days to make a year on Mars.

Daisey Moreno, IL | (none)
Daisey IL Do you think that if we put another planet on mars would it change the co2 in to oxygen or what would happen?

Jennifer, NY | (none)
We can't live on Mars becuase it is too far away for people and it doesn't have any gravity or water and by the way Mars in pictures looks cool!!!!

Dear Hermoine, a satellite is either a natural or man-kind thing that orbits a planet. Dear Ayay in Cali, Mars does have frozen ice caps that are dry ice (frozen CO2). Dear Kaela, (scroll down to see post) i've heard that they're trying to find out how to make oxygen, water, and other stuff we need to survive. Dear Neji in Cali, (scroll down to see post) because it has a larger orbit than Earth. Anymore questions? (lol)

Elizabeth, OH | (none)
I wonder if life was on mars a long time ago...scientist have found evidence of rivers.What happened to the rivers if there were any is all they have to figure out!!!

another person, UT | (none)
Ok poeples.....Cuke, I agree, they have proven that there are no lifeforms on Mars. Mars does not have a sun but if you meant moons....there are 2, Phobos and Deimos. And also, would aliens just look like us???

Kevin, UT | (none)
What do you think what would happen if we put a plant on Mars....would it really change the CO2 in to oxygen???

Cuke Grower X1, FL | (none)
Dear Cole of Wisconsin, NO. The answer is NO. Don't keep your hopes up, the entire planet of Mars has been tracked down by probes and there is no sign of life, until humans colonize it. Sorry! This one goes to Iyana A. of Wisconsin also. Mars has no suns at ALL. There's only one sun in the Solar System. That's THE Sun itself! To Logan of Florida: Mars has no suns!!! Just revolves around THE Sun. Since you both have almost the same postings, Prince of New Jersey and Chalie of New York: Nice ideas, but according to science there are no aliens on Mars in the first place. But, Chalie, there is no proof that aliens wouldn't spy on Earthlings... who knows? They could, Chalie, they could...

Dan, PA | (none)
Mars is not the only planet with craters. Mercury is full of them. Even Earth has craters. One of the most famous ones is in Arizona and is about 1 mile across. The reason the Jovian planets (Jupiter, Saturn, Neptune, and Uranus) do not have craters is because they are primerally made up of gas and liquid. Try making a crater in water. Also Venus does not have visible craters because the atmosphere is so dense it burns up most objects. Also the highly active surface seems to errode craters away after they form.
