Do mars have a thick atmosphere?

Don't mars look a little bit like earth on those hubble's photos?
Whit clouds and ...water!

Plus any aviation buff knows than airplane as a top altitude it can reach before the air get to rare to support lift for it.
So why nasa want to send an airplane to mars?

Robot Airplanes Could Unlock Mars Mysteries

Various orbiters, landers and rovers that have explored Mars in the past three decades have revealed tantalizing evidence of the conditions for life, from frozen water at the planet’s North Pole to methane plumes in the atmosphere. For atmospheric scientist Joel Levine, the evidence has made the case for flying an airplane over Mars stronger than ever.

Levine champions the ARES Mars airplane mission at NASA’s Langley Research Center in Hampton, Va. He believes that a robotic, rocket-powered airplane is the perfect platform for unraveling the Red Planet’s biggest mysteries.

Soaring at an altitude of 1.6 kilometers, an airplane could cover hundreds of kilometers, gathering visual images and remote sensing data that it transmits back to Earth.
"A powered airplane flying a mile above the surface can obtain measurements over inaccessible parts of Mars and collect a whole bunch of data that no rover can collect," Levine said. As opposed to orbiters, meanwhile, the airplane would be close enough to the ground to get high-resolution images and chemical sensing data.
ARES, which stands for Aerial Regional-Scale Environmental Surveyor, is Levine’s brainchild. He has now formed a team of 250 people, from airplane designers to mission planners to bring his vision of a robotic airplane soaring above Mars to fruition. The team has built and tested a prototype ARES airplane and they are gearing for the next NASA Mars mission solicitation.
The ARES airplane prototype is 16.4 feet (5 meters) long, with a wingspan of about 21 feet (6.5 meters), and is made of a lightweight polymer-carbon composite material. It would be packed with its tail and wings folded into an aeroshell similar to the one that brought the rovers to Mars.

About 12 hours away from the surface, the carrier spacecraft would release the aeroshell, which would descend to the surface aided by a parachute. Thirty-two kilometers above the surface, the airplane would be ejected, its wings and tail would unfold and the rocket engines would ignite.

Levine is most interested in flying ARES over the mountains, craters and volcanoes in the southern highlands, where it hasn’t been possible to land safely until now.
The plan was to piggyback the chosen craft aboard an Ariane rocket launched by the French space agency CNES. The airplane flight through the Martian atmosphere was to take place on Dec. 17, 2003 to commemorate the centennial of the Wright brothers' first powered flight.

NASA chose the Langley Research Center team to lead the effort, with Levine as the project scientist for the mission. The project was cancelled later that year for budgetary reasons, but he has since been convinced that an airplane was the way to go for Mars exploration.

Levine believes airplanes could offer an affordable and reliable way to explore Mars. Missions such as the upcoming Mars Science Laboratory, slated for 2011, may be more difficult from a technological standpoint, he said. [6 Facts About the Mars Science Laboratory]

"An airplane is deployed in the atmosphere," he said, "so you don’t have to worry about landing on rough terrain or retro-rockets and firing at precise times."

Aerial Martian recon

Airplanes would be ideal for observing large regions at close range, said Charles Whetsel, manager of the advanced studies and program architecture office at NASA’s Mars Exploration Directorate.

To date, however, he says Mars exploration has been conducted with orbiters, landers and rovers, because they typically have long lifetimes of months to years

NASA is proposing to send a small robotic jet plane to Mars to cruise areas of interest. The plane is called ARES and is folded up origami like and pops open and takes off into the wild red yonder, sending data back to Mother Earth in real time.



The device has specific targets and is equipped to seek specific evidence. It will be flying at about 450 MPH and looking for source of unusual magnetic signatures and also evidence of methane, a byproduct of life.



I wasn’t able to find any info on the propulsion system or the proposed life expectancy of this thing, but as soon as it runs out of fuel it will be just some more scrap on the pristine Martian landscape.

Funding is pending, and if approved the launch date is projected to be in 2016.

So what is the bs the hubble photos?
Or the other photos of mars,were it's red and dry?
That nasa want to send an airplane on a planet whit only less than 1/1000th of earth air pressure?

AND WHAT ELSE IS A BLATANT LIE?

Well its simple really.
See the plane has larger wings to accommodate lower pressure and create some lift by additionally compensating with speed. All you have to do is go faster to achieve same affect as on earth where the atmosphere is thick.

Check out planes for reconnaissance, they were created to work in extremely low pressure and scarce atmosphere high up (U2 was the first one). They were fast and had large wings.

High up in our atmosphere is no different than lower down on mars.

I am using this topic to draw your attention to the "Elephant" pic of Mars. LAVA FLOOD DRAWS ELEPHANT ON MARS.

Just select the "eye" portion of the "elephant" . copy that portion, paste it, and enlarge it a thousand pixels....

If the object ends in an 's' like Mars (with a capital) because it is a name your thread should read:

Does Mars have a thick atmophfherie.


Poor Jess.....

In answer to the question, if you fly there on a magic carpet you will find the answer is - no not really.
