A world first. New footage from Mars rendered in

stunning 4K resolution. We also talk about th
The cameras on board the rovers were the height of

technology when the respective missions launched.

A question often asked is:

'Why don't we actually have live video from Mars?'

Although the cameras are high quality, the rate at

which the rovers can send data back to earth is the

biggest challenge. Curiosity can only send data

directly back to earth at 32 kilo-bits per second.

Instead, when the rover can connect to the Mars

Reconnaissance Orbiter, we get more favourable

speeds of 2 Megabytes per second.

minutes each Sol, or Martian day.

As you would expect, sending HD video at these

speeds would take a long long time. As nothing

really moves on Mars, it makes more sense to take

and send back images.
