Horizon goes behind the scenes at NASA as they countdown to the landing of a 2.5 billion-dollar rover on the surface of Mars. In six days time, the nuclear-powered vehicle - the size of a car - will be winched down onto the surface of the Red Planet from a rocket-powered crane. That's if things go according to plan: Mars has become known as the Bermuda Triangle of space because so many missions there have ended in failure. The Curiosity mission is the most audacious - and expensive - attempt to answer the question: is there life on Mars?
Playback servers
Subflix keeps extra fallback servers tucked away by default, and if one stalls it will still try the next available option.
Now playing
Strong fallback server when you want a second path ready without leaving the page.
If the provider's own fullscreen button throws an error, use Subflix fullscreen or open the player in its own tab.
Playback mode
Playback continues in a dedicated viewer designed to keep the watch experience simple and steady.
Cast And Share
These providers run inside an external iframe, so the most reliable casting flow is to open the player in its own tab and use your browser or device cast controls there.
Preparing your player
MoviesAPI is loading in the watch shell. If it takes too long, Subflix will offer another server.
