Obsolete Probes

The deep-space probe uses directional measurements of the red shifting of scan signatures due to space-time expansion to give very coarse scanning of objects up to interstellar ranges. You only need one such probe for analysis, and it scans everything within 1000AU.

Lith probes pick up the diffraction of quasar emissions around large stationary objects in space, and utilize the resultant interference to estimate the distance at which the objects lie. The Quest probe is the longest-distance lith probe available.
