NASA plans to launch a 4K TV channel this fall and has already begun test broadcasts, PCWorld reports.

The new channel, called NASA UHD, will broadcast 24 hours a day and be available free of commercials, according to a promotional video currently being broadcast alongside NASA’s existing channels on the AMC-18 satellite.

Initial programming will be based around eight different video series: Liftoff, ISS Life, Deep Space, Development, Solar System, Earth View, Mars and NASA Classics, PCWorld says.

It will likely be welcomed by owners of 4K televisions who face a shortage of 4K material to enjoy, but how they will receive the channel is unclear. It will be broadcast in HEVC, a new format being proposed for global 4K broadcasting.

HEVC-compliant satellite receivers are not widely available so currently direct reception is only possible with a powerful PC with a built-in satellite tuner. And you’ll also need a large satellite dish for the C-band service. So it’s likely the channel won’t be easily available until subscription cable and satellite providers carry it.

A taste of the programming on offer has been offered by NASA since January this year on YouTube. The space agency started uploading content shot in 4K to stream online and the videos do look amazing.
