Proba-3 infographic: Double spacecraft mission

The two satellites have been designed with maximum commonality in functioning and configuration. Both spacecraft share the same power generation and onboard data handling systems:

Occulter: Weighing about 250 kg, the cube-shaped Occulter bearing a 140-cm diameter disk will fly with the same face toward the Sun at all times. For the mission’s science operations, it casts a precisely controlled shadow onto the Coronagraph spacecraft. The Occulter is responsible for performing the high-accuracy formation control using cold-gas millinewton thrusters, producing minimum force equivalent to a single falling feather. The DARA radiometer is mounted on the Occulter’s Sunward side.

Coronagraph: The 300 kg Coronagraph spacecraft hosts the mission’s main ASPIICS coronagraph instrument. Like the Occulter, the spacecraft is designed to point the same face at the Sun. Flashing LEDs and a retro-reflector for lasers are mounted on the Coronagraph’s face to help guide the Occulter. Because the Coronagraph will often be shaded it possesses a single side-mounted solar panel to generate power. The Coronagraph has monopropellant thrusters to perform newton-scale manoeuvring.
