Nasa lies about Mars atmosphere.Helicopter to fly in Mars" 0.6Percent of earths atmosphere"

You don't seem to understand how aerodynamics work. A helicopter designed to fly in thin atmosphere at 38% of the gravity isn't going to fly in thin atmosphere at 1G well. It will fly at low altitude where the air is thicker.

Because very few fixed wing aircraft are designed to fly anywhere near that height. The only reason the scout will be able to fly on Mars is because of the lighter gravity, and the extremely short flights it will make.

Hi sorry you dont seem to understand.


Earth pressure at 20km is 0.79 Psi

Mars pressure is 0.088.

This special nasa drone should be able to fly to the upper limits of outer space where there is only 0.6% of atmospheric gases left compared to sea level.

100% atmospheric pressure, the comparison point on earth.
0% atmospheric pressure = zero atoms for a rotor.
No gravity, no gas, no pressure, only a vacuum in empty space 273- degrees.

Official story says mars has 0.6% gas of earths (density). That simply is not enogh for even a paper airplane to fly. It will go straight down and have no lift. 0.6% is basically nothing. Moon was 0%.

Wrong again, not that anything will change your mind. A craft designed to operate at 38% gravity, making very short flights isn't going to work at 1G near space.

They could prove it simply flying it in a tor chamber, filled with Mars atmosphere gasses and at that air pressure.
No need to risk millions of bucks testing up there, with winds we have no idea about and obvious monitoring and recovery.

Are you joking. I looked at a pic of this thing and even a Dji phantom is more complicated.

Oh, if it doesn't fly they have a backup model to put in some barron land here on earth where we can get occasional coke cans and lizzards in the pictures that they forget to edit out.

They want money for their project, it does not matter if it is real. The money coming in is real.

I made a list of planets atmosphers. The mars atmosphere is slightly different then I mentioned earlier but very close.

mercury: basically none
venus 1,350 psi
earth 14.7 psi
Mars 0.13 psi
jupiter 29 psi
saturn 20.3 psi
uranus 17.4 psi
neptune 14.5 psi

Oh look what an accident. Only mars has no atmosphere. Demotivating anyone from going there since no atmosphere = dead planet dont go there. Seems like a decades old conspiracy to me to try to prevent people from going to mars.
Data has been faked from the first landing on Mars with a pressure sensor.

Nasa designed an airplane in 1970 for Mars. Weight 40-100Kg.
How can a rotor based propulsion system at that weight fly at a 0.6% dense atmosphere. There is basically nothing to rotor through.- Yea lets think about that.

Also how does a parachute work on mars if its only 0.6%. It cant. Nothing to hold onto.

Mars is dense, theres probably a base already with 100 people.

Ofcourse, you ask, why would they lie. Well its quite easy if you think strategically.

Nasa lies about mars atmosphere because it could ignite a space race there.

As NASA Says to the world...Hey do you like Apples? How do you like THEM Apples...? Lol

//Tldr: Nasa lies. Mars cant have 0.6% of earths atmosphere. //

TLDR; You're not an aeronautical engineer so you can do the calculations, and you think nobody else can either.

They have already made a test flight in a Mars-like atmosphere with gravity-assist to simulate Mars gravity and it worked. It's not easy though:

Can a Helicopter Fly on Mars? NASA Says Yes

NASA actually has been working on developing a helicopter that could fly on Mars for decades now, as Bob Balaram, the project's chief engineer at NASA's Jet Propulsion Laboratory near Pasadena, California, explains via email. But solving all the technical challenges was a daunting task.

"A helicopter for Mars has to be tough enough to survive the journey to Mars (high g-loads, vibration, etc.) and the environmental conditions it will face in space and upon arrival (nighttime cold, etc.)," Balaram says. "The design of such as vehicle also has to address the unique aerodynamics in the thin Martian atmosphere, which imposes challenging weight constraints on the vehicle design. It has been possible to meet these stringent mass constraints only recently, with the advent of lightweight electronics (e.g. cell-phone components), and battery technology (e.g. Lithium Ion cells)."

In order to achieve lift in an atmosphere that's the equivalent of being 100,000 feet (30,400 meters) in altitude on Earth — more than twice the maximum height that helicopters have reached on this planet — the Mars copter's blades will spin at 2,300-2,900 revolutions per minute, about 10 times faster than Earth helicopters do.

One of your problems in trying to compare numbers directly is assuming the design is the same. The design is not the same, so your assumption is false. Look at this design, it's not like a normal helicopter, you can tell by looking at it:

Nothing special in that helicopter. It is a clear psyop with the dude with masks and everything.

An Esky Big LLama helicopter is basically the same. This is a similar looking one:


Where is the limit when a helicopter cant fly? 0.1% atmosphere of earths? 0.2%? 0.5% At one point you run out of atoms which to gobble through with your rotors.

And thats a fun insult, " You're not an aeronautical engineer"

How do you know? If

That dude in the picture is not. Thats a hobby rc drone and 14 year olds can build those,. If hes an aeronautical engineer, then i am too.

Nasa has a secret space mission and thats the real secret that no one wants to tell anyone but hey its their loss. Im sure theres a lot of unfound einsteins in the 330 plus million Usa population and 500 plus European population etc. Well whatever.

This is comedy gold!

Maybe you could sketch up what a Mars helicopter should look like?

Well mars helicopter would look like that. Thats my point.

The atmosphere is much denser then they admit. Thats the point. It is not 0.6%.

One day when an objective mars probe will land on marc, which they wont shoot out in thousand pieces, it will measeure mars atmosphere to be maybe 70% of earths.

Pressure is density. Density is material. 0.6% is 0.6% of material from earths. no material no lift. Imagine an chopper trying to fly through 0.6% dense air. It wouldnt even move off the ground.

They will one day admit mars has higher density when its too obvious to hide.
