Then where is the proof. You provided a video of a rocket that stop before the rocket even enters space. The rest is just cgi. The cgi is the movie gravity was much better by the way.

Right there is your problem. You base your ideas on how things work on science fiction fantasy - go on the space forums and you'll find all sorts of people criticising the scientific inaccuracy of 'Gravity'.

I posted footage that predated CGI of rockets working in space. Proven it fake yet?

Yes edited video and cgi. Now it’s augmented reality

You have proved no proof. Only your hearsay and slander against people giving first hand accounts of traveling to and back from space.

I would think weather imagery and weather data from weather satellites proved by local news, national news, the weather channel, and internet weather sites would be proof of satellites in orbit placed by rockets....

Or just seeing the international space station travel across the night sky......


Images from the Hubble space telescope....

No. Once again, no. Claiming something is CGI is not the same as proving it is. The footage I posted is from the 1960s. Care to show what CGI capabilities existed back then? I know the answer, but I'm willing to bet you don't.

Lol every video is edited or it’s cgi. You still can’t prove that rockets work in space/

You are cgi. Prove I'm wrong.

Placed this item into space:

Sentinel-1A

en.m.wikipedia.org...

Sentinel-1A is a European radar imaging satellite launched in 2014. It is the first Sentinel-1 satellite launched as part of the European Union's Copernicus programme. The satellite carries a C-band Synthetic Aperture Radar which will provide images in all light and weather conditions. It will track many aspects of our environment, from detecting and tracking oil spills and mapping sea ice to monitoring movement in land surfaces and mapping changes in the way land is used.

Launch

Sentinel-1A was launched on 3 April 2014 by a Soyuz rocket at 21:02:31 GMT (23:02:31 CEST). The first stage separated 118 seconds later, followed by the fairing (209 s), second stage (287 s) and the upper assembly (526 s).[6] After a 617-second burn, the Fregat upper stage delivered Sentinel into a Sun-synchronous orbit at 693 km altitude. The satellite separated from the upper stage 23 min 29 s after liftoff.

And produced these radar images

Sentinel-1A Satellite delivers first Radar Images of Earth

spaceflight101.com...

The newly launched Sentinel-1A satellite has returned the first images acquired with its high-fidelity radar system. Sentinel-1A is making good progress in its commissioning phase that will prepare the satellite for regular acquisition of high-resolution and calibrated radar images for release through the European Commission’s Copernicus program.

Following a close call in the first night of the mission that featured an unprecedented Debris Avoidance Maneuver (a story told here by the mission team), Sentinel-1A continued its early operations with flying colors – being awarded a clean bill of health and beginning to collect radar images of chosen targets on Earth.

This is some of the access offered by the European Space Agency from the Sentinel Program

sentinel.esa.int...

Sentinel data products are made available systematically and free of charge to all data users including the general public, scientific and commercial users. The data will be delivered within an hour of reception for Near Real-Time (NRT) emergency response, within three hours for NRT priority areas and within 24 hours for systematically archived data.

All data products are distributed in the Sentinel Standard Archive Format for Europe (SAFE) format.

Each mode can potentially produce products at SAR Level-0, Level-1 SLC, Level-1 GRD, and Level-2 OCN.

Data products are available in single polarisation (VV or HH) for Wave mode and dual polarisation (VV+VH or HH+HV) or single polarisation (HH or VV) for SM, IW and EW modes.

How to get Sentinel data

Access to Sentinel data via download

sentinel.esa.int...

The free, full and open data policy adopted for the Copernicus programme foresees access available to all users for the Sentinel data products, via a simple self-registration. News and further information about the service is available here.

Are you going to post blatantly false arguments concerning all the data and services provided by in orbit satellites placed into space by rockets to keep trolling. How much of your credibility are you willing to sale out on to keep
Trolling?

Can satellite data b faked? Can aerial images from airplanes be used as “satellite footage”? I think you aredy know the answer.

You still can’t prove that there is an equal and opposite force from gas movement due to pressure gradient force

Do you have any proof the images from the Sentinel one are fake? Any thing to contradict or show the Sentinel-1 mission team and tracking team are lying?

Anything to show that satellite weather imaging and data is faked? That the tracking and mission teams are lying.

Anything to show the satellite programs of various nations to map the moon are faked? The mission and tracking teams are lying?

And you never answered how the mirrors on the moon used with earth based lasers to measure the distance to the moon got to the moon.

Your refusal to ignore cited sources, your refusal to ignore the numerous explanations by individuals, and your refusal to acknowledge the daily use of space satellites place into space by rockets is not proof of the lie rockets don’t work in a vacuum.

Again.
Think about it this way. The gas exiting from the rocket is basically a controlled explosion. If the reacting gassed were not in a nozzle, the exit gasses would want to expand in all directions. Is that false. In a rocket, the gas release is forced out in one direction. Is that false. So the gas is required to push against the combustion chamber. Is that false. The expanding gasses by contact and collisions is forced out the nozzle opening. Is that false. So by Newton’s third law, the expanding gasses forced out of the nozzle by contact will result in thrust for the rocket. Is this false. Using Newton’s third law to move the rocket has nothing to to with the atmosphere. Is that false.

For the exhaust gas to get out of a rocket motor, it has to push against the walls of the rocket motor creating a “For every action, there is an equal and opposite reaction.” Is that false.

Do the people on here that think a rocket has to push against something external to move the rocket know how a firework works.

Do they honestly think the air is providing the resistance to push against yet that same air cannot provide enough resistance to stop my hand moving through it.

Do you think air provided enough resistance for Saturn V or Shuttle to take off.

This is basically the theory I have on moving up to light speed using thrusters that move you in space. If you get to a certain speed by orbiting a planet or two a couple of times, I would think it made sense that since you're in no gravity, a thruster that can boost you forward in no gravity would only thrust you faster and faster since there's nothing in empty space to slow you down. Eventually, and with enough boosts, you could get up to the desired speed.

I guess an easier way to say it would be like this. If you're moving 126,000 mph through space and you're attached to the front of the craft, if you jump forward with, say, a force equal to 10 mph then you would be moving 126,010 mph.

Reminds of the old question, can an airplane take off on a treadmill.

And the answer to that is "Yes."

All the treadmill will do is make the plane's wheels turn faster. It won't stop the plane's propeller/jet engine from moving the plane forward.

The wheels are generally free to spin freely, and thus the spin rate has no real rigid connection to the rest of the plane (other than friction, which is relatively minimal and can be overcome). The thrust provided by the propeller or jet engine doesn't care what the wheels are doing.

You can speed up or slow down (or even reverse) the treadmill all you want and the wheels will just change speed as the plane's thrusting engines moves it forward.

What about wind drag on the wings to lift the nose off the ground?

How is the treadmill affecting that?

Again, the only part of the plane that notices that there even is a treadmill are the spinning wheels. And those wheels spin freely, independent of the rest of the plane.

The rest of the plane will act as if there is no treadmill, and the plane's propeller or jet thrust will move it forward at the same speed (relative to the solid ground and air) whether there was a treadmill or not.

So the treadmill is not affecting the forward speed of the plane relative to the ground (the non-treadmill ground) or the air, and is not creating additional drag on the wings. It's only making the wheels spin faster.

a reply to: LSU2018

No difference treadmill or not..the planes wheels are free spinning, not driving the forward motion..the propeller does that.

FFS! Get yourself a 10 gauge goose gun, put the butt up to your chest and fire it. The bruise on your chest and your butt after you land on it will teach you all you need to know.

You must be very bored.

Mythbusters man, and they are not CGI

so Nicsign is still disproving videos by just saying fake, I gave up pages ago, I asked for actual proof and let Nicsign decide the timescale for their thorough breakdown of the video, all we got was 'its CGI', not which program was used to create the CGI, not what effect to make the 3d image of the earth, nothing zip nada, why do you take so much effort to log in and say the same things than actually discredit the videos in an investigative manner.

This thread is CGI, crap grande intelligent-less





Here is another non CGI rocket, surely Nicsign you can tell me how they made this effect, if you answer this one in detail could you please do the same for the other videos offered



Nicsign you should check out the UFO in Jerusalam video on ATS and how it was proven to be fake, with actual evidence found and presented, it turned a wanna be beliver like myself to the truth, their is nothing better than the truth, it is claimed it can set you free.....its up to you mate
