Here’s a big question: How did life begin on Earth? We don’t quite know, but this fundamental question is a driving force behind astrobiology research at NASA. Understanding how life originated on our planet could inform us about the potential for life to exist throughout the universe.

Join us for a fly-through of the International Space Station. Produced by Harmonic exclusively for NASA TV UHD, the footage was shot in Ultra High Definition (4K) using a fisheye lens for extreme focus and depth of field.

A world first. New footage from Mars rendered in stunning 4K resolution. We also talk about the cameras on board the Martian rovers and how we made the video. 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. 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. Credit: NASA Music from Epidemic Sound
