  1. it would make sense that if the atmosphere is 1/100 that of earth the rotors would have to spin 10x or the square root of the atmospheric pressure ratios or Earth and Mars. this could cause a big problem when trying to land as ground effect would kick up dust back towards the rotors . now all of a sudden the atmosphere is 10 times thicker ( Quasi) and kaboom the rapidly rotating rotors disintegrate.

  2. I’m assuming they were testing that thing in a vacuum chamber cause all Mars has to offer is .006 atmospheres… or does it?

  3. From what I se, electrostatic energy rules the universe everywhere. No, the size of a planet or mass, or even a gas giant, has no effect on its gravity, only condensed energy between water or gases of all kinds on the surface of the planet, and the interior of its nucleus.

  4. Of course, this does not apply to mars, which in the event of a collision loses water and its gravity has been disturbed and will be decreasing for the next millennia.

  5. Only the electrostatic energy is able to keep the galaxies and cause in the galaxy something like gravitational lenses, and not, as they think, black matter or, as I say, its droppings.

  6. Stars, just like the sun are parasites, so that their surface fires up to such high temperatures, it needs oxygen gas and various minerals contained in the planets and the sun activity is closely related to the tragedies on the planets and when after some millennia it is able to pull this cosmic dust to itself and can feed on it, the meteorites do not kindle our star, the reaction is short as in the case of cosmic dust, it drives the star and cosmic dust is needed for its reaction, and when the planet begins to die the sun increases its surface trying to absorb these planets .

  7. If there is no air during the explosion of a bomb or something else, we will stop this process, we call it implosion. Such an takes place in the sun.

  9. If in an electronically controlled engine (I'm talking about cars) we use implosion in the lower part of the piston, then we will not need an additional load on the bearing.

  10. The atmosphere of the planet Mars is composed mostly of carbon dioxide. The atmospheric pressure on the Martian surface averages 600 pascals (0.087 psi; 6.0 mbar), about 0.6% of Earth's mean sea level pressure of 101.3 kilopascals (14.69 psi; 1.013 bar). It ranges from a low of 30 pascals (0.0044 psi; 0.30 mbar) on Olympus Mons's peak to over 1,155 pascals (0.1675 psi; 11.55 mbar) in the depths of Hellas Planitia. This pressure is well below the Armstrong limit for the unprotected human body. Mars's atmospheric mass of 25 teratonnes compares to Earth's 5148 teratonnes; Mars has a scale height of 11.1 kilometres (6.9 mi) versus Earth's 8.5 kilometres (5.3 mi)

  11. Would love to see Mars 2020 launch on a Falcon Heavy !!!!!
    btw the best part of naming the martian rover '2020' …….. NASA can't delay it ??

  17. A mini helicopter huh ! Ya, the budget is shot, but come on what kind of junk is this. the defense contractors already knows just about everything there is to know about what we should be talking about and thats drones and not small ones either 24 inches to 30 inches or larger with a range of over100 to 500 miles. Thats what this, quote, high tech nation should be talking about instead of this flimsy junk and their cheap to build to no in depth research needed thanks to the defense industry.

  31. i hope the legs wont have "balls" at the tips since these could get stuck in rocks & make it tip over. It must be like a cylinder going up, then tapering toward the center part

  36. Could do with some form of directing a small amount of downdraft onto the solar panel or at least some form of clearing the dreaded dust especially after landing. Just a whiff if charging drop off is sensed…just a thought…

  37. Не взлетит этот марскит. 2400 об/мин при давлении менее 1% от земного и тяготении в 40% – ему нужно около 7000 оборотов и вдвое большие по площади лопасти (а может и больше). Параметры воздуха совпадают для нашей высоты в 30км – не знаю я таких вертолетов и не представляю энергоемкость такого полета – а температуры там очень низкие для использования любых аккумуляторов без подогрева. На высоте 30км могут летать военные истребители на скоростях выше 3000км/час – можно прикинуть какая должна быть частота вращения для лопасти в 1,2м – длина окружности с таким радиусом 7,54м, 3000км/час=50км/мин, 50000/7,54=6631.об/мин – это очень упрощенный расчет, не учитывающий огромного количества факторов, потому могу смело предположить, что вертолет не получится. Желаю удачи и опровержения моих предположений.

  42. Huh, won't it tip over when there is wind?
    It says that it weighs 4 pounds which is roughly 1.8 kilogram, and I assume that's on earth.
    With the Mars' gravity of 0.378g, the helicopter would only weight 680grams! I'm looking forward to this.

  56. What powers the helicopter? WE THE PEOPLE gave our space program away to a few corporations, even though our tax dollars still fund NASA, Nasa works for/supports/subsidizes the corporations to go into space (corporate "free stuff"). Why all this effort to put rovers and helicopters on Mars for corporate America? becasue they are looking for minerals and other riches. When they find them, will the American people be entrusted with the resources? Will they be respected? Or will they be used to fund programs for the people? Of course not. Everyone knows this. The American people are subsidizing this hunt and planned exploitation, for a few greedy corporations who will get all the money (One which was formerly known as Halliburton) and no doubt pay no, or next to no taxes on any gain. We can also predict that corporations that we give corporate welfare to, to exploit mars, will mar the planet, they will pollute, leave trash and industrial waste. The space program is becoming a subsidy program for corporations who will exploit and violate the beautiful red planet.

  62. The Mars helicopter will fail
    and this is why.

    The softball-sized "marscopter" weighs about four pounds and is
    fitted with two sets of rotor blades, which can spin at 3000 rotations a minute.
    Too much technology and the lack of endurance is what I’m basing
    my option on.

     I may not be a “rocket engineer” but I have
    worked in the world of mechanical engineering over many, many years.

     NASA’s little helicopter is the size of softball This "marscopter" weighs
    about four pounds and is fitted with two sets of rotor blades, which can spin
    at 3000 rotations a minute and as a
    drone will have to land no matter what batteries or power supplies it has. Yes
    I did see that NASA/JPL  did  design a rotor blade assembly incorporating
    the use of photovoltaics The possibility of damage to either rotor blades is of
    high risk. If the rotor or motor should fail because of the abrasion of fine particulates
    in the Martian atmosphere it will become immobile. Also there is one more point
    that makes this impractical is wind. (Gravity still works just as well on Mars as
    it does on Earth)

    Given that Mars has only 0.7% of
    atmospheric pressure of the Earth, the rotor blades would be of such a size it
    would be an impractical design (Most helicopters can fly up to 25000ft at its
    maximum. A black hawk can fly up to 10000ft. Indian Chetak Helis can fly up to
    20000ft but remember your dealing with Earth not Mars.)

    Now I would use an older
    technology and that is a powered airship. Yes a lighter than aircraft!  It will carry a heaver payload than any
    helicopter you could ever launch from the surface of Mars.

    If the motor failed on it would
    not crash and its payload will keep functioning. Although it would be at the
    mercy of the winds on Mars. (The wind speeds that Viking observed at its site in summer is
    2 to 7 m/s (5 to 16 mph) The wind speeds at Viking site in fall is 5 to 10 m/s
    (11 to 22 mph) and the wind speeds at Viking site in a dust storm 17 to 30 m/s
    (38 to 67 mph). At higher altitudes, the movement of dust was
    measured at 250-300 mph. This may sound
    fast but you have to realize that weather balloons on Earth frequently traverse
    the jet streams without harm.)

    A lighter than airship can be made
    buoyant neutral and gather samples from a wide range without difficulty and
    return to its base following a homing beacon and dock. This base could also be
    used as a return vehicle and return samples to Earth if needed. The docking
    station could use an electromagnet on a swivel as to face into any winds when
    docked It could also use the  photovoltaics
    on the top of this airship to supplement power at the docking base for running
    tests on any samples retrieved and download photos or videos for transmission
    back to Earth.

  63. I thought no craft could fly because the atmosphere is really thin? and sometimes turbulent? If that thing works on mars, it would be a great addition to all other toys already there !

    Reply

  65. I think if drone can fly in Mars, the drone must be lightweight and the fan have to spin really harder because Mars's air pressure is 6/1000% Earth doesn't it?

    However, I really interested in this project. I hope this project can work ><

  71. Mars atmosphere being what it is. I’d be interested to to see something like that even work.
    Looks to me like the blades needs to be much larger, very thin, flat surfaces to catch the nearly nonexistent atmosphere.
    Don’t think those tiny blades will be able to move nearly fast enough to do what they are expecting.
    Unless!? Those flights they were showing were being done in a large vacuum chamber with 99% of the atmosphere removed.
