Conversation so far:
What is Home Plate?
During 2007 Spirit spent several months near the base of the Home Plate plateau.
When did the global dust storm occur?
Towards the end of June 2007, a series of dust storms began clouding the Martian atmosphere with dust.
How did the dust storms affect the rover?
The storms intensified and by July 20, both Spirit and Opportunity were facing the real possibility of system failure due to lack of energy.
Did either end up experiencing a system failure?
In early August the storms began to clear slightly, allowing the rovers to successfully charge their batteries.
What did the rovers find?
In September and October it examined rocks and soils at several locations on the southern half of the plateau.

Question: Did they explorer anything else?
Self-contained rewrite: Did Spirit explorer anything else besides the examination of rocks?
