is mars really half the size of earth? seems small..

Oh I'm rally sure that we are not alone but when we are gone find a neighbor we are gone have a lite surprise …

looking for water…..there are plenty of water over at enceladus….why not try there

I think we all are from MARS. Mars may be the our first land! after the development of sun the life has moved to earth! just a thought

Tate Butthole March 26, 2013 - 11:41 PM

lololololololololol…. open your mind -_-

Bill Chen March 28, 2013 - 3:16 PM

wrong in 500 ways

kcking23 April 14, 2013 - 10:49 PM

how do you know if it's wrong,mars was once suitable for life but due to many solar storms that weaken the magnetic barrier of mars and cause the land to be harmed from radiation similar to what we're undergoing if we keep polluting the world and weakening out magnetic field.

Are there any videos longer than the commercials?

WhatTechShow April 25, 2013 - 7:58 AM

They're recruiting people to live permanently on Mars. Haha. NO THANKS.

I think only homeless people or people with a miserable life and no family would consider going to Mars… :l

I would say it wrong because humans only recently have the ability to travel 90 million miles.

kcking23 May 7, 2013 - 11:15 PM

idk what you talking about but just because someone can just travel 90million miles doesn't mean they're from where they're from.

jordy May 17, 2013 - 5:29 AM

please tell me we're not running out of water because if it happened to mars it could happen to us and i don't want Earth to turn into mars

jordy May 17, 2013 - 5:31 AM

it would be cool to be able to live on the Earth with aliens

its amazing how many people have fallen for this fairy tale

jhenningkelloggia June 6, 2013 - 3:04 AM

humans can travel 90 million miles… but… we have a 15 mile high range to do it from… space travel is a fairy tale

Our magnetic field is beyond our ability to manipulate. It is generated by the planet's core, and is not affected by anything that we do with technology. I think you are thinking of the ozone layer, and ozone depletion at the poles which is a combination of the magnetic fields being weaker in this particular location, and global warming who's processes are affected by but not caused by mankind.

Vonar Roberts June 16, 2013 - 3:20 PM

So explain to me how curiosity got to Mars if not via space travel?

jhenningkelloggia June 16, 2013 - 7:46 PM

well… I dont know how to tell you this exactly… but… they are faking the whole thing… maybe its filmed in Nevada and edited in Houston… I dont know… but I do know… they aint on Mars no more then Santa Claus is on the North Pole

kcking23 June 17, 2013 - 7:33 AM

Not Earth, i was talking about mars,it was once habitable and supported water,air,and etc according to scientist several asteroids making huge impacts might have wiped the field/barrier down causing the atmosphere to weaken by solar storms/winds and making mars to what it is today.

Vonar Roberts June 18, 2013 - 3:57 AM

Yes, in the early age of the solar system scientists believe that Mars was hit by at least one if not more massive impact events about the same size that made Earth's moon. However because Mars was too small, and did not have a moon like our own it couldn't recover from this impact or impact(s), and the core ceased to function like Earth's. Over a billion years that atmosphere and the majority of the water that was not frozen in the poles was swept away by the solar wind, and you get Mars today.

Vonar Roberts June 18, 2013 - 4:06 AM

However you also mentioned or suggested that human-generated pollution weakens the magnetic field here on Earth, which is complete BS and right up there with the hysteria over the development of Smart Grids as the magnetic field is generated by the core of the planet, and can't be affected by day to day human activities….

Vonar Roberts June 18, 2013 - 4:15 AM

….. Gotta love how completely those German's, American's, Soviet's, European's, and Chinese all completely fooled us….. I suspect you believe that every launch starting with the first V-2 test launch back in 1942, some 70+ years ago was a fake?

jhenningkelloggia June 18, 2013 - 4:26 AM

they were designing and testing rockets to carry warheads

Vonar Roberts June 18, 2013 - 9:18 AM

that is the dumbest theory I think I have ever herd…… If you truly believe that the last 70 years of space flight has been a hoax explain to me where is the economic rationale to build a rocket the size of the Saturn V of the N-1 to launch warheads? You don't need that much Delta-V to launch a large number of tiny MIRV warheads which are smaller then 99.99% of the world's satellites into Orbit….

jhenningkelloggia June 18, 2013 - 10:29 AM

the Saturn V was designed to carry warheads… the N-1 being the Russian counterpart… there is no such thing as a 'nuclear' bomb… or 'atomic' bomb… those are propaganda hoaxes to scare somebody, I'm sure…
and there is no such satellites flying in space… they are not necessary nor possible

Vonar Roberts June 18, 2013 - 12:24 PM

Your officially the dumbest person on the planet if that is what you believe…………

im nathan June 18, 2013 - 11:24 PM

This is probably stupid but what if we send a bear to mars? Not the huge bear, the microscopic one. It is said to be the strongest organism in our planet, right? Therefore, sending it to mars in some sorta box which supervises it would be sort of a good way to examine whether or not bears could survive in mars. Just sharing what I thought of.

We are not.
