I have just watched this video and since I consider myself to have an open mind I find some the arguments quite compelling.

I agree wholeheartedly withn the two previous comments and that is I asked those very simple questions about the video. What appears to be happening is that nobody wants to answewr but just look for non-related issues in order to side-track.Some people have said that there is plenty of room in an open mind to contain enormous amounts of rubbish.
I am not one of them. I believe that an open mind is a very good thing, so long as it is safeguarded by a good sense of discrimination.

Still no reply to my video questions!Many, like me, will be more than happy with Rod's statement.

You've never lost anything or accidentally thrown something out? The people who work at NASA are just as human and you and I. We make mistakes.Yes but what about the lost Moon flies and data?
Go to the bathroom and fill the tub with water. Now cup your hand and slowly enter it into the water. Do you get a big splash? Do you get a large ripple? Now do the same thing, except this time, hit the water as hard and as fast as you can. Do you get a big splash? Do you get a large ripple?What about the parachute problem?
As I understand it, this is how it works. A NASA Technician sends a command to the rover via radio (not the Internet). Let's just say that command tells the rover to move forward ten feet. About eight minutes after the command is sent, the rover receives it, verifies it, and executes it. Assuming the execution of the command completed successfully (the rover is now ten feet from it's previous position), it sends a signal back to Earth saying it successfully executed the command. Approximately eight minutes later, that signal is received by the NASA technician and the next command is sent (turn left 10 degrees").What about the rover control instructions?
What bolt/screw? All I saw was a blurry strip of brightness. Provide me with a link to any other web site that states it was a fallen screw. The second image was taken over two minutes later and from a different angle.What about the removal of the bolt?
These answers are just as viable (if not moreso) as the one provided in the video.These are all questions that people like me who have an open mind want answers.
With respect the questions about the Mars Rover video nhave not been answered.I believe that a 12-year old could read and understand post #4.
I do not intend wasting my time on answering 12-year old's questions, which have already been dealt with in a proper and understandable manner.

Moon files and data. Are you serious! It's just a simple mistake? I can't imagine any right thinking person accepting such an excuse.You've never lost anything or accidentally thrown something out? The people who work at NASA are just as human and you and I. We make mistakes.

Your hand represents the parachute. The water represents the atmosphere. If you're moving too slow, then nothing happens. If you're moving fast enough, the chute opens.

It's not like you have someone sitting in a gaming chair with a VR headset on, driving the rover around.

Go outside on a sunny day. Find a sidewalk that has a bit of shade running across it. Place a rock on the edge of that shady spot; half in sunlight and half in shade. Now wait two minutes. Is the rock still half in sunlight and half in shade or has it changed?
These answers are just as viable (if not moreso) as the one provided in the video.
Which answers you choose to believe are entirely up to you and your "open" mind.

Tell you what. Why don't you tell us what answers you WOULD accept and we'll see what happens.These answers are not viable they are just poor attempts at trying to justify what is patently questionable.
Moon files and data. Are you serious! It's just a simple mistake? I can't imagine any right thinking person accepting such an excuse.
Parachute problems. You have ignored that they do not work on Earth in the upper atmosphere.
Rover control instructions. I think you are over simplifying the possible cammands that could be sent! I would like to see you control an RC car with an 8 minute delay.
Disappearing bolt. The point is whatever it was in one photo it is missing in the other.
These answers are not viable they are just poor attempts at trying to justify what is patently questionable.
I don't have any answers, that's why I asked the questions. If you don't either then I guess the video is creating problems.Tell you what. Why don't you tell us what answers you WOULD accept and we'll see what happens.

Interestingly what I observed in my Moon-Sun thread is not what everyon believes about the Moon's illumination. We appear to have double standards here.FYI. If folks watch the 9:12 minute video in post #1, the first two and half minutes discuss Mars and show a Nikon camera image of Mars along with other Mars images compared to NASA image of Mars. The claim is, Mars looks like what the video shows and NASA uses CGI, Mars is not a spherical planet suggesting the planets are more like stars. In October 2020, Mars came to opposition and I used my 90-mm refractor telescope and 10-inch Newtonian to enjoy Mars views, seven times that month, from 40x to 216x views. My log shows 27 Mars observations I conducted using my telescopes from 07-May-2020 through 19-Jan-2021 using my telescopes.
On 02-Dec-2020, I viewed Mars and close conjunction with the star HIP4978, ~ 7' angular separation in Pisces. Visible together in same field of view at 129x and 200x using my 90-mm refractor telescope with TeleVue products. The star is a double and at 200x, barley visible as a double, ~ 1.5" separation according to Stellarium 0.20.3.
I can testify that the Mars images shown in the first minutes of this video is not what I observed using my telescopes. If questions need asking, I would start right there.
I think the video was saying that even with RAD the parachutes would still have to open but there is not enough atmosphere density to allow this.I note this comment in post #12, "Parachute problems. You have ignored that they do not work on Earth in the upper atmosphere."
https://mars.nasa.gov/mer/mission/spacecraft/entry-descent-and-landing-configuration/parachute/, "Rocket assisted descent (RAD) motors: Because the atmospheric density of Mars is less than 1% of Earth's, the parachute alone cannot slow down the Mars Exploration Rover enough to ensure a safe, low landing speed. The spacecraft descent is assisted by rockets that bring the spacecraft to a dead stop 10-15 meters (30-50 feet) above the Martian surface."
Going back to my post #13, the 9:12 minute video presented in post #1, 2 1/2 minutes at the start show images of Mars, as Helio says in post #16, "are patently false and absurd.", good words I would use to describe the difference in what I see in my telescopes when viewing Mars and this video argument against NASA showing what Mars really looks like.
Again you are ignoring how a parachute operates in the thin air of Earth's upper atmosphere proved by Joe Kittenger which is an independent source.
NASA tested the parachute design using NASA Wallops Island (see link, 2 minute video). The rover is descending at some 1500 mph or near Mach 2.0 in the very thin martian atmosphere. In 0.5 second, the parachute deploys and opens. Even in very thin air, the velocity of descent and force measurement in newtons or dynes is sufficient to deploy, e.g. 10 km up at Mars and coming in fast. The video provided in post #1 is fraught with misconceptions presented to the public.
The comment made "Parachute problems. You have ignored that they do not work on Earth in the upper atmosphere." is a misconception or misinformed source(s) used in this thread.
