Solar Probe Beta is one of two specially designed payloads that are both used in Mission 12 to study SOL, the other being Solar Probe Alpha. Beta is distinguishable from Alpha by its red rocket engine housing; Alpha's rocket engine housing is blue.

Both probes must be simultaneously managed during space flight due to time constraints to successfully complete this mission.

Both Solar Probe Beta and Solar Probe Alpha are medium-sized payloads, and do not actually have a function in the game, much like a Communications Satellite.


  • The mission briefing describes the probes as having special shielding to protect the probes's sensors from the intense heat of SOL, but if they are maneuvered too close to SOL they will still be destroyed.
