Follow master rigger Sean Riley to the Mojave Desert, where he teams up with NASA for one of the biggest fixes yet: the DS-114 Mars Antenna.

We'll get under the hood of this nearly 7-million-pound giant to switch out a critical part of the enormous hydrostatic bearing, allowing it to resume its accurate tracking capabilities.
