An exploded view of LISA Pathfinder

Date: 27 August 2015
Satellite: LISA Pathfinder

This exploded view shows the LISA Pathfinder spacecraft in its entirety.

The solar array provides power to the LISA Pathfinder payload and support systems, and shields its sensitive payload from the Sun.

Beneath the array is the white and gold-hued science module (covered in multi-layer insulation), which carries the payload with the test masses and their electrode housings, the optical bench interferometer, and vacuum enclosure. All of these components fit neatly within the central cylinder, which in turn slots into the centre of the science module.

The science module also contains support systems for LISA Pathfinder's scientific experiments, and carries micronewton thrusters on its outer panels to adjust the position of the spacecraft.

The propulsion module at the bottom of the exploded view will help LISA Pathfinder reach its final orbital location.
