How do spacecraft navigate in space ?

  • katma 7 Ara 2017
    How do spacecraft navigate in space over billions of kilometers and with split second timing during missions that last for years or decades. Here we look at how its done and the underlying principles that make it all possible.

    "Sign up for free"...the first to sign up will get a 20% discount on their subscription.....
    So which one is it????? How can one sign up for free, and then have to pay for a subscription. This is not "free".
    No worries, it seems that many youtubers are doing the same thing. It is a bit confusing. If you would like to be part of a solution, perhaps consider clarifying whether or not you are asking people to pay for a subscription, and not trying to drive sales by starting out with "free"....
    Just the opinion of a viewer.

    Thanks for the content by the way:)

    When something intersect planet, planet's speed decrease? Is it possible that if big enough thing intersect planet, planet's revolution orbit will changes alot??

    I remember the New Horizons mission, as I flew to Queensland to visit the observatory to watch the event live, with live chat and commentary with the leaders and physicists from NASA. A truly awesome event, watching the live (albeit delayed) feed from the spacecraft.

    Conform Einstein theory even the light could curve because huge stars gravity ,the gravity can curve even the time ,In the event orizont from one black holle, the time could be stoped, and this singularity can does absorve even the light, even it can not escape from this huge gravity force ,the black holle are the ultimate destroyers nothing escape !

    I knew a guy that had almost no formal education, but with two glass tubes attached to 50 feet of rubber hose, could prove the unrefutable principle that water always seeks its own level. What length of rubber hose would you have to attach to those glass tubes before the water would no longer equalize and display level?

    Its sad that I learn more about Science and Space stuff on these videos More then i ever did in Public Schools growing up. This guy is passionate about the subject. He doesn't stick to just 1 book like we all did in school for each subject like. 1 math book for math class. 1 book for government. Ect. Hes pulling from multiple sources and displaying them out as he goes. If he was a teacher he would go from video to video. And pull up the charts and maps on the main board. Like seriously teachers today can't do much like that anymore. They don't the right to change it up in there own class teachings since the board of education won't let them. And alot of the times today teachers don't get paid well and most end up looking at it as a job and don't do it well and mess up helping kids and not teaching them right. They tend to be boring and give less teachings and throw test out without completing the teaching of what we are ment to learn. Morale becomes low and kids begin to careless of a person who doesn't care about them. Sad. Specially since the REAL Subject we all need in this world to learn more about to help give curiosity and interest of the future never gets taught at all about. Space. Thats a subject we must focus on to build a future! And Farming agriculture to grow and hunt to sustain food and the environment. To bad the governments don't care for the environments and future technologies. They to busy starting wars over power and getting oil. We as humanity need to progress now or never. I mean its 2019. What is our future from now? Its The year Akira and Blade Runner happen lol. We need to do more for our future

    For you "lovers of space conspiracy and flat Earth":
    Go and tell the Chinese (who just landed a rover on the Moon) about your conception of "fake" space travelling. Go and tell them that "No matter which "fact" you choose about space achievements, not one of them is verifiable independently."
    They will love to hear form you.
    And I believe that Donald Trump would also thank you personally.

    Navigating in space will be simple. I citethe 1940s pulp Captain Future. There is a bit where his robot pal Grag is ejected into space. Grag simply heads for the "most heavily-trafficked space lanes" until a passing ship rescues him.

    As opposed to these self righteously indignant, I mean intelligent, people who call it "urannus" I was always told it was called the former, not the latter, and have only recently have people tried to change its' pronunciation because despite all their intelligence they cannot wrap their brains around the fact that a planet was named after some asshole somewhere.

    The notion that conservative of energy causes objects passing within orbit to speed up while causing planets to slow down is self-debunking. He said if you pass a planet going the same direction , it will speed you up and slow the planet down. If a planet were to change its speed of rotation or orbit of the sun, the planet surface would be a smeared clean, just like your face when it goes through a car windshield in a wreck.

    The entire solar system is traveling through space. The planets are orbitring the Sun. And moons orbit planets. Right? With all this motion in multiple directions, how is it physically possible to travel from planet to planet? I'm familiar with the argument for why the ground doesn't move beneath planes in-flight. But that involves the atmosphere moving in perfect sync with the spinning planet. In the vacuum of space, how do you explain a "spacecraft's" ability to keep up with the ever-moving solar system? If there's no atmosphere in space to keep objects moving along with it the way atmosphere supposedly does on Earth, what's the real trick to interplanetary travel???

    14:17 "The power of the signal from Voyager I's position is about 20 bilion times less than a modern digital watch uses."
    This sentence doesn't make any sense.
    Emitting power of the Voyager's radio or what? Received signal strenght (term power makes no sense in this case) or what?
    What you mean modern digital watch? There are hunderds of different constructions? Radio controlled watches maybe?

      Okay, never mind … I thought your question pertained to how spaceship computers know the spaceship’s orientation without the benefit of a compass (a question I realize upon reflection probably everyone knows the answer to, from grade school, and that day in science class the teacher had someone holding a moving bicycle wheel sit on a spinning stool) but you’re addressing the mechanics of orbit, Hohmann transfer, gravitational assist, the sticky wickets of acceleration and deceleration in our solar system’s clockworks. Good stuff, my bad!
