    Landing a rocket propelled spacecraft is "not impossible", says the guy playing a computer game.

    I'm sorry... that was a very argumentive statement to make. I realized my mistake soon after making that comment, and meant to edit it into some kind of question that would spark discussion. But I never got to it. So I hope you'll forgive me and allow me to ask a question: How did you come to conclude that it's impossible to land a spacecraft on its thruster?

    Do you think that a human could fly and land a rocket on it's main thruster with out computer aided guidance?
    Relying solely on a pilot's skill, and gumption?

    Space X managed to fly a rocket straight up into the air, and then land it back on it's own foot print, which was a major feat.
    Here's a few space x landing scenes.

    Notice example 4 and try to imagine the instability of landing a rocket. Do you believe that any person could ever make the required flight corrections while sitting on the top of this rocket? Because to land the "lunar module" the onlty thing that could slow the descent is a rocket, because there is no atmosphere (so no parachutes, or wings).

    Top quality 2010's grade sensing and computing still produced failures. There is zero margin for human error.

    It is an impossible feat.

    If this was possible, then we'd have rocket powered aircraft that landed on landing pads somewhere on the planet. Those do not exist in 2019, because it is folly.

    Note that the landing platforms are all on level landing pads, or the deck of a large ship.

    The probability of fortuitously landing on a firm level surface on the moon are close to zero.

    The probability of landing in some portion of a loose gravel crater is extremely high.

    Yet we're expected to believe that NASA landed 6/6 successful missions on the moon, and then took multiple series of perfect photographs?

    It was impossible feat in the 60's.

    Oh wow. Those rockets do look quite unstable. They're very tall and have those short legs, those would be hard to land under human control. I wonder why number 4 exploded.

    But the lunar module looks quite stable to me. It's short, and its legs stick out.

    And according to this article, the lunar module DID have computer assistance:

    On final descent, Armstrong noted that the automatic landing system was guiding Eagle toward the boulder-strewn floor of a crater the size of a football field (”West Crater,” not shown below). Armstrong took manual control and skimmed over the crater, landing in a flat plain beyond. Eagle had only about 30 seconds’ worth of fuel left at touchdown.

    Do you have any other reasons why landing a lunar module would be impossible, other than the instability of SpaceX rockets?

    The fundamental challenge to landing is the inherent instability of landing any/every rocket.

    Can you name a single rocket type aircraft that a human has ever landed on Earth; and walked away from? I'd like to see a video of this if you can find one.

    Every person to ever take a flight in a rocket landed by some other means.
    The rocket was abandoned at some point in flight, and the pilots parachuted down, etc. The pilots never landed using the thruster. Ever.

    The obvious reason for this is landing a rocket propelled craft by controlled thruster descent was literally impossible, at the time.

    I found a video, but first: Why are rockets inherently unstable? Are jets and propellers inherently stabler?

    [–]Tom_Bombadil[S] 3 insightful - 1 fun3 insightful - 0 fun4 insightful - 1 fun -  (9 children)

    Aircraft use wings for lift and stability.

    There's no atmosphere on the moon, so wings are useless for stability. Beyond the rocket power there's no stabilizing forces. It's 100% thruster controlled.

    Oh, so you mean like how if you use the thrusters to rotate a spaceship it keeps turning until you manually cancel the rotation? (or turn on a killrot autopilot)

    [–]Tom_Bombadil[S] 1 insightful - 1 fun1 insightful - 0 fun2 insightful - 1 fun -  (7 children)

    Manually cancelling the rotation of a freely floating object would be close to impossible.

    I like the approach, but all these examples seem to fail the pyramid.

    Especially the 3rd one, the Vaccine depopulation. I've only done history (extra) in High-school, but Look up the Spanish-flu and you have the answer for a depopulation scheme...

    And to take this an an example, what is truth, I highly doubt any of the saiditers is somewhere near and virologist (which vaccines are against) and even if a saiditer is a virologist... how to prove this without doxxing itself and showing somekind of 'shoe on head' photo with credentials within a 30-minute time range?

    I'm saying this because, as and IT-person and having read a lot of studies (8 in my study and some unaccounted for in spare time) it takes (especially in STEM-studies) a lot of self study to even begin reading them. I can't imagine the specialties you should have read upon in virology...

    I would (though it would be very cumbersome) propose to have the claims (upon discrediting some research) explained.

    Example:

    MSM: claims Mnemonic is a dick

    Me: Starts a submittion by saying, MSM article is wrong it is [explaining in my words their claim (so people know what you think)] {aka Mnemonic is a dick}.

    But! This is wrong Mnemonic is not a dick because [link to scientific study (and then explaining in my words what that article says)]

    This way people can criticize the article AND my 'explanation' I got from the article. (because I could have read it wrong, got some terminology wrong, something else wrong).

    This is probably the most involved of the group, as science has been hijacked for this one. Climate change has been hijacked similarly, but with a bit more obvious weaknesses.

    Also, this one was included intentionally as it is an issue that many here disagree with.

    I accept your challenge.

    Unfortunately, dealing with the shills is a more pressing issue.

    Would you be surprised to learn that certain NGOs are being sued, because sterilization drugs were found in their vaccines??? Would that pique your interest?

    Also, don't get the flu shot, until I can get into the specifics. ;-)

    Would you be surprised to learn that certain NGOs are being sued, because sterilization drugs were found in their vaccines??? Would that pique your interest?

    No (not surprised) and Yes (would probably get my interest) and that would suggest these sterilization vaccines are being distributed in Africa. And again, please who les proofs.

    Though usually it's the science behind vaccinations that's being questioned or the engineering of the western distributed vaccines (why lead/mercury usage in them?) and I've never seen those studies that say the mercury/lead is bad in those concentrations.

    BUT

    If you posted an article and your conclusion (which may well be these accusations) I could better make up my mind, as would everybody else. I used it as an example because I only know Extreme Christians that use religion as counterargument to vaccination.

    K. Dr computer.

    We'll address this later.
