Makes You Wonder Why NASA NEVER posts VIDEOS of mars

maybe

NASA Mars Video Archive

plenty of NASA Mars videos there.

Umm because it would take up a lot of storage space on the rover and would probably take hours to days to send the data that far..

wehateporn is that you?

Because Zerohedge doesn't equal with Nasa. You should broaden your news sources, etc.

.

There is no money in Mars.

Do you have any concept of how long it takes a radio signal to reach Earth from Mars and how fast (slow) the data transfer speed is.

It's very expensive in terms of resources to make videos from the cameras of rovers and use valuable bandwidth to send those back when in the same time many photographs of greater detail could be taken along with the associated instrument analysis accompanying the subject of the photograph.

Moving data through the solar system is SLOW because of the vast distances involved and the need for error correction. It takes about .2 of a second for a single ping on the Internet to go from Melbourne to Los Angeles and back again.

In the case of mars it takes up to 26 minutes for a ping to go over the Deep Space Network (DSN) from Earth to Mars and back again.

So depending upon the distance from Earth to Mars (this changes) for every packet of data sent from Mars to Earth there is 13 minutes for the packet to be received and another 13 minutes for an ack to be sent back. If the data sent is corrupted somehow and it needs to be resent then that process needs to be repeated.

Now obviously the DSN doesn't just send single packets back and forth, it's more parcels of information, but the same principle applies.

With all that said, NASA do take video from both rovers and their orbiting counterparts, but it's of things which are of specific interest like storm formations or atmospheric changes that can be recorded on video in either the visible or infrared spectrum. These do exist on the NASA website.

Your tin foil hat is on to tight

Take a deep breath, and try to relax.

yeah, but what about the ACTUAL exploration.... thats the only video? lol

yeah..those are just photos compiled into a video.. im talking about like a GO PRO version of the rover moving around the red planet

its because they are used to TGPs, wait for them to get the tubes then you'll see the shit hit the fan

Read my explanation above, which is based on fact not your funny ideas about "anomalies".

one toke over the line ...

it's not difficult

and do we have to mention the energy constraints re: recording video?

nevertheless,

10+ years of Rover eye view video

Last time they posted a pic there was a woman there

sending back video wasn't really a mission objective either::::

Scientific Objectives

The rover's Primary Mission was planned for seven sols (Martian days). The rover was designed to interact with slightly more than 300 square meters of Martian terrain, though initial operations were conducted within a limit of 10 meters or less of the lander.
Primary objectives for the rover were 1) exit the lander as early as practical on the basis of lander stereoscopic images, 2) send initial vehicle performance and technology experiment data to the lander, 3) move a few meters and repeat objective #2, 4) acquire and transmit images showing the condition of the lander, 5) acquire images at the end of daily traverses for navigation purposes, or encounter, acquire, and transmit an image of a rock or soil patch for subsequent APXS analysis, 6) deploy APXS on the imaged rock or soil patch, if possible, for 1 to 10 hours duration for chemical analysis, 7) query the APXS for final data and transmit interim and final data to the lander, and 8) traverse diverse terrains and repeat objective #2.

An Extended Mission of 30 sols was planned and more than realized, as the governing spacecraft, rover and site-related factors permitted rover activities to continue for 81 sols. Extended Mission objectives were similar to the Primary objectives, with technology experiments amended to explore the diverse terrains further away from the lander.

As during the Primary Mission, Extended operations of the rover cameras were to yield a high resolution image dataset critical for navigation purposes and geologic analysis of structures in rocks and soil-like materials. The rover image data were to contribute to the technology experiments by affording high resolution stereoscopic and multispectral examination of 1) features targeted for APXS chemical analysis, 2) slumped or eroded surface material that had been excavated by the churning rover wheels, 3) aeolian effects on the exposed, upturned material, and 4) overturned rocks. This would aid in achieving the scientific objective of better understanding surface material properties such as grain size, bulk density, friction angle, cohesion, and compressibility, which could then be put in the larger context of geologic features seen in the lander IMP images.

Of the ten Technology Experiments, rover camera images were acquired to support the following six: a) Terrain Characterization, b) Basic Soil Mechanics, c) Wheel Abrasion, d) Thermal Characterization, e) Dead Reckoning and Path Reconstruction, and f) Vision Sensor Performance. For a description of these experiments, refer to [MATIJEVICETAL1997A].

Rover Camera Instrument Description

just watch a grand canyon video in the dark, same thing.

if they did a go pro video of this https://www.youtube.com/watch?v=gZX5GRPnd4U

(IN COLOR)

why not do a video of the rover GO PRO style maybe just 2 minutes worth or so while exploring the planet. hmmmmM?

Obviously this is all being filmed in Bill Gates' backyard.

You either cannot read, are trolling or are extremely stupid.

It takes up to 9 hours to receive and process a single image, it can be more it can be less, so lets say 24 frames per second to save bandwidth.

24 frames * 120 seconds = 2880 images.

2880 images * average 4 hours when Mars is closest to earth = 11520 hours = 480 days

That is if there are no errors in receiving the data.

The DSN has enough trouble receiving continuous streams of telemetry let alone images and video. What you're talking about is not trivial.

If they never post videos of Mars - how do you know anomalies exist in the videos?

Bandwith? since when did nasa' bandwith become limited

I explained this in an earlier reply.

The data transfer speed is less than a dial up modem, taking up to 13 minutes per packet of data to arrive to Earth from Mars, then each packet needs to be acknowledged (ACK) and then another piece of data transmitted in a process that can take as long as 9 hours for a single image, it's sometimes less and sometimes more depending on how close Earth is to Mars and the amount of error correction required.

Radio waves can't travel faster than the speed of light.

It's called packet loss

many providers meter bandwidth these days.

Hey! WTF!!! Please curb your facts! This is GFY after all. Just dream up random reasons and present them as facts if you want to fit in here.

Finally, science.

Because ...

Verizon has really shitty galactic data plans.
