In this week's episode of Watch This Space, we take a look at what went into getting InSight onto the Martian surface. We take a look at the "seven minutes of terror" (the time between first hitting the planet's atmosphere to the moment it safely lands) and how NASA did it without any real-time input from Earth. 

From the complex calculations to the precise commands that had to be pre-programmed into the spacecraft, InSight was a triumph of human achievement and a sign of just how much we've advanced in the world of space travel. And it's just getting started.
