There are a total of fifteen signatures in Greater Mars today.
Ten of them are gravimetric.
The other five? Wormholes. All five of them.
This is the most wormholes I’ve yet seen in any one system.
Only one is to high sec space. There is also one to low sec, and then one each to “unknown”, “dangerous unknown”, and “deadly unknown” space.
Outside the wormhole to “deadly unknown”, I found a cargo can with a salvager, a high-meta web, and some scan probes.
