Mars in 4K

Extraordinary images captured by NASA’s robotic rovers are giving Earthlings their first look at Mars in state-of-the-art, ultra-high-definition video.

The cameras on board the rovers were the height of technology when the respective missions launched. 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.

However, this link is only available for about 8 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.

This documentary was created using digital photos shot by three NASA rovers — Spirit, Opportunity and Curiosity — and beamed back to Earth.

They were then “stitched together” to create the illusion of a camera panning across the desolate and barren landscape — and provide what the narrator calls the “most lifelike experience of being on Mars.”
