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.

    if it takes voyager 40,000 years to leave the suns gravitational pull, but the sun is also moving through the universe and say it is moving in the opposite direction of voyager, would that effect the amount of time it would take voyager to leave the suns gravitational pull? Or is that part of the calculation?

    Using Jupiter's mass, its orbit slowed about one foot per trillion years. I assume this is from calculation instead of observation.

    So...., if voyager 1 leaves sun's gravitational pull; Does that mean it orbits around the center of our galaxy ?

  • Charles Brightman

    At about 4:00 in the video, with gravity eventually pulling the satellite to Earth's surface, same principal with our solar system being pulled toward our galactic center, and our solar system doesn't have any thrusters to maintain a circular orbit around the galactic center, hence also why we exist in a spiral shaped galaxy. Orbital velocity plus gravity acting upon the object and it eventually 'falls' toward the center of gravity in a spiral fashion.
    Not only are only those species that make it our of this solar system potentially going to consciously survive while all other Earth species most probably die and go extinct, but so too, only those species that make it out of this galaxy potentially are going to continue to consciously survive while all other Earth species most probably die and go extinct.
    We NEED a pro-active space program to get out of this solar system and out of this galaxy (and then of course, where are we going to go then?), otherwise, we are ALL going to die one day from something, will forget everything we ever knew and experienced, and will be forgotten one day in future eternity as if we never ever existed at all in the first place, and life itself would all be ultimately meaningless in the grand scheme of things, at least as far as Earth species go.

    If an object is NOT in orbit, say between the earth and moon, why wouldn't there be gravitational effects on indviduals? I've learned over time ZERO G in orbit is actually continually falling, not really zero gravity per se. Like the vomit comet, but youre falling AROUND the planet. Silly question, but it's kinda bent my mind a little.

    Our main problem would be not to damage our Earth, not to diminish the power or rate of gravity or to lessen the gravity that our planet should change course and smash into other planets or the sun however to utilise the weight and speed of our of our planet and convert that into a magnetic field a magnetic a road that would then throw us across the universe this might be our way into the Universe and back home from where we came from huh? Hay my names Dave hinds by the way and and I am homeless tehehe

    If the space junk is not enough metallic content in it then use the shuttles a space tugs to bring huge metallic asteroids tethered above our planet or based upon or around the moon with their power transmitted through contacts terminals placed above the Earth which when charged directly react upon the force of our planets gravity creating a magnetic force field with which we can ride upon to travel around the universe? Any good?

  • martel hinds
    martel hinds 17 gün önce

    Ok I have just checked and a google search came up with this :-19 Jun 2013 - Gravity is a force acting on an object with mass, magnetism is a force exerted by virtue of charged particles. Both are based on ferrous material, one is created by mas the other by the movement of the mass. I suspect gravity is a direct result of a magnetic field. Right so what we need to do is get a couple of space shuttles up there in orbit with a great big net they drag the net around our planet grabbing up all the metallic space junk up there we then squeeze it all together and then charge it against the movement of our planet thus creating a force field :-one is created by mas the other by the movement of the mass one playing against the other could our very own planet be a natural form of energy and an interstellar form of transport which allows us to travel through the heavens from galaxy to galaxy using nothing more but nature itself?

  • martel hinds
    martel hinds 17 gün önce

    No Gravity is somewhat like magnetism could we therefore not utilise a magnetic force created by the Earths metallic core and the Moon making a magnetic bridge from one planet to another that we could hover upon similar to how some of our trains hover upon a field of magnetism of increasing speeds the greater the object the greater the pull perhaps?

    I have a question: The further the away from earth we are the faster time goes. Which I think I'm correct on? This is why people / US / Russia have to keep the GPS satellites timing correct. So my question is, how much time did the Apollo missions lose while they were away from earth's gravity when they visited the moon? - Love your vids btw the way just intrigued (or curious ;) ) On time and moon travel, how much older are they on their return?

    few kilometers up in the skies and we are floating as the Gravity of earth diminishes, and obviously they are not sucked up in space due to anther Gravity affect from another planet! So tell me what Gravity you talking about that the Rockets are Using! Complete Bullshit if to think the Planets as they claim are moving in Incredible speed in space that mean once a Rocket leave Earth it will be sucked into the unknown like jumping from a speedy car! If the Sun have that incredible Gravity effect on Earth due to the Mass Of Earth .... What Mass does the Rocket has to be pulled by the sun or any other Planet?!!!!!!!! Another bullshit claim of Gravity shit!!!
