Why didn't they take a video recording device to Mars? I know there isn't much to see, but surely it wouldn't even cost that much compared to the rest of the project? How awesome would it be to see recorded film of a different planets atmosphere? Just to even be able to witness something like that.

Fuck you NASA.

Video takes significantly more space and bandwidth to transmit and every fucking milligram costs millions so no.

>fuel to power them

Curiosity is powered by a nuclear-decay fueled thermocouple. Using less or more energy doesn't deplete its fuel faster or slower.
Its power output is more than enough to run a video camera.

>Transmitters and harddrives

Terrabyte usb sticks are available on the commercial market. NASA couldn't afford a big enough drive to record video? Doubtful. You can transmit a file of any arbitrary size using the same arbitrary-bandwidth transmitter, it just takes longer. They wouldn't have to *only* use video, but having the option seems worth the (miniscule) cost.

A flash drive isn't a normal hard drive, but we'll ignore that.

>What do you think the Radiation would do?
...Not much? Nothing more than it did to the hard drives on the Apollo missions, the ISS or the shuttles? X-Ray radiation and microwave radiation don't affect flash media. You're worried about cosmic rays? They could damage data on the drive, eventually, but they wouldn't physically damage the drive itself or impair its functionality. I don't think you know as much about space as you think you do.

The curiosity camera can take sequential photos at reasonably high framerate and have them stiched together as a video.

But guess what, it would look just like a fucking photograph because pretty much nothing ever fucking moves on mars.

They did.

>The cameras can take true-color images at 1600×1200 pixels and up to 10 frames per second hardware-compressed, video at 720p (1280×720).

Now the reason why they didn't take a high speed full HD 4k fancy pantsy cameras is that the bandwidth availible is SHIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIITEEEEEEEEEE

>Therefore, most of the data returned by Curiosity (MSL), is via the UHF relay links with MRO and ODY. The data return via the communication infrastructure as implemented at MDL, and observed during the first 10 days was approximately 31 megabytes per day.

It have some other comms instruments too that can increase this slightly. But the point here is still that you have a upload budget of approximately 12 gigabyte PER YEAR.

All the computers used on those mission had expecific hardware. For fuck's sake, even the MoBos have to be certified against radiation to be considerable for a mission.

Also, there actually are researches on the effects of radiation on flash drivers, I fail to remember any titles tough.

If it were an analogue video feed could that send more pictures faster then going digital?
