Judging by what appears to be in the soil, I think we should produce glass from silca sand, and iron from the iron oxide, and build at least one other dome while we're here.
We may be able to condense out some atmospheric water, or bake some out of the rocks, especially underground rocks.
With any luck, we can have a fully functioning terrarium before it's time to go. It would be a nice present to future settlers to have a shelter set up for them, with food available.
As for mining the iron and silicates out of the soil, we're on it. Setting up a reactor core for large scale smelting and oxy burn-off. The atmo is already CO2, so getting things hot enough to dissociate into 2CO for catylizing the Fe3 out of raw soil should be a snap. Silicates and making steel could be a bit more tricky, but we are looking pretty good so far.
