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.

    >Science Facts over Science fiction
    Talking about terminology, wasn't science fiction, if not fiction itself supposed to be plausible in real life?
    If not it is science fantasy?

You guys honestly believe we can remotely control something that is over 6,000,000,000 miles away? When does the "fact" that the solar system is moving through space at 514,000 mph come into affect?

    What would the universe look like if an object were suddenly stationary in space? Obviously the earth and sun would move away from you as it orbits the Sag. A, but how fast would it recede? Is it possible to be absolutely stationary? I don't believe the Hubble Constant and Dark Energy-driven accelerated expansion model (and I'm not alone), so seeing space expand between galaxies would imply our stationary object would be stretched, right?

    this is a load of shit - space is a vacuum and nothing works in a vacuum without air. the solar system is moving in one direction and we are expected to believe space ships are moving the opposite direction towards the end of the solar system. NASA fakes space because it doesn't exist like they say it does.. earth is flat and motionless and easy to prove. there is no observable or measurable curvature - its that simple, they hide it because they never mention it or teach kids of any grade how to measure the earth.

    • RogHawk
      RogHawk 22 gün önce

      Donnie Creel It all has to do with a balance of forces, with the quick ejection of gasses from the rocket nozzle giving the forward momentum, not the pushing against an outside medium. Same way opening the end of a balloon would propel the balloon in space, it also works for the rocket. Here is a page from NASA's rocket educational site that explains the physics in brief.
      And the much larger Rocket index page with is very extensive on learning all about rocketry of all types, its equations and more:
      This short PDF should serve as quite helpful as well:
      The main thing about atmosphere is that it creates a lot of drag for the rocket, which slows the rocket. Once in space, the acceleration is limited only by the amount of fuel carried!

      RogHawk because anyone with a brain knows you can not turn, slow down or speed up in a vacuum.. objects in motion stay in motion. Bowling ball feather??? NASA’s own test in a vacuum.. Hello McFly.. there is not one single scientific experiment that can prove different. And I don’t mean some asshole in his back yard with a vacuum tube and a fire cracker. Rockets in space are a joke and a complete lie.. BUT lets say ( just for fun), that you could move a rocket forward in space, your 100% not gonna slow it down with out an equally big rocket shooting it in the opposite direction ... this is common sense stuff and I’m sick of ppl continuing the lie of rockets in space. This isn’t like ppl saying flat earth. This is real
      Science and there is no proof to the contrary

    Are you talking about the vacuum of outer space? Where there is no air? I don't believe you have ever been to space. How can your internal combustion engines work in a vacuum. You (science) does not know how "gravity" works. Your can't even strike a match in space. No air. Your engines can't produce a spark... no air. You are all a bunch of good storytellers though. Also, you can't "see star"s in space (so said several astronauts on camera.) You all need to get your stories straight. This stuff is all fantasy.

      Gloria Jean You did post a reply to which I gave a short reply, but it seems to have disappeared. Thanks for the heads up about the one site, which seems to be the archive for the Russian Electro-1 satellite images. It appears to me that they have made it so it needs a log-in now. The rest of the links appear to work based on testing them just now.
      Yes, I saw the Robert Bassano video when it was first uploaded. I can find nothing of value with essentially a prank caller, who has gotten no information to help with his ruse and assertions. As for ThriveandSurvive, I'm not sure I watched that particular video, but keep in mind that this is the guy who couldn't get his head around the path of the sun in the sky in northern and southern hemispheres, and came up with the most facepalm-worthy assertion of the "frowny face" path of the sun. Flerfers in general seem to have trouble with visualization and frames of reference.
      The color composite you referenced from the Osiris-REx probe refers to four wavelengths of light combined to make a color image, just as the weather satellites use filters to take many wavelengths in separate exposures of the whole sensor. It is not a composite in sections.
      I've provided you with countless images of Earth from space, able to be cross-referenced between different satellite images of the same wavelengths at the same time. Yes, the people who put up the DirectTV satellite decided to put an off-the-shelf webcam onto the sat which was in geosynchronous orbit. A pretty interesting idea!
      You will find, eventually, that the "rabbit hole" you revel in now will turn out to be a snake's den when you realize that the entire "FE/fake space" thing is a trolling internet meme. When someone I knew got into it a few years back, I did as instructed, and did my own research, and found the major charlatanry which is its hallmark. It would be considered laughable, except for the scam artist aspect of continuing to lie for TRclips monetization, and Patreon and Paypal dollars for the larger channels which try to extend the life of the prank for as long as possible. A lot of people who lacked critical thinking and basic science knowledge are going to be very embarrassed in the future.

      Gloria Jean Seems like most you are providing is argument from incredulity. Which is what I have to present to you as well and say "Do you really believe Robert Bassano was ever a "graduate student?" Yup, why would the person on the other end of the phone have seen the Hubble himself? I've seen most all of the FE vids as I've made this internet meme a study of mine for over two years now. It's fascinating from a psychological point of view, to be sure. Why would anyone believe a worldview with no supporting facts? I don't get it.

      Gloria Jean Yup, all from HoaxTube. The same area of the web that saw a an internal lens reflection of the sun and tried to convince people it was the doomsday planet/sun "Nibiru".
      Rocket engines... Well, the very short answer is that they carry their own oxidizer to go along with the fuel. Given how easily found that fact can be found tells me you haven't tried to look into it. Also here's a simple technical breakdown of rocket engines.
      The Hubble is in orbit around the Earth not much higher than the very real ISS, and takes long exposures of distant objects. Turning it towards the Earth would be like using a telescope to look at objects on your desk. The only time it is done is to get a grayscale image to calibrate exposure and check the sensor through the necessarily undetailed image.
      You can find many photos of the Earth. Most are from international weather satellites. There are some great visible light images from DISCOVR and Himawari-8, however.

    All of this math says that the affect of a possible graviton particle is slowly affecting an objects own rotational period, which we observe on a macro scale. But on a subatomic scale of inter-nucleitic activity, this transition of energy does not have an effect on the equilibrium of the equation, based on our current sensitivity of measurements. We could surpass lightspeed through a gravity jump this way, but the physical forces would exceed what our math says is possible, that the energy of that transition would exceed the energy in our measurable universe, and tear the object transitioning, apart.
