Look, I'm not exactly pleased to be here either, but this much of that green ore is too good to turn up. Yes, the moon is increasingly unstable but carve as much as you can using the rockerizer, get it back to the tele unit and we're out of here in an hour. Not the time to be asking why we aren't sending a bot. If we had the money for one we wouldn't need to be here. It's a very decent payday.
Your hazard suit will absorb a fair amount of punishment from the molten rock, but the surface instability means it's leaking between gaps in the ground. Nothing like a bit of motivation eh? It'll mean your journey back to the TU will be trickier than the outward trek, so use the nano waypoint device to mark a path back. Anything marked will have a bright yellow glow in your HUD just like the TU. It's got limited juice though, so go easy. Oh yeah, worth saying - just remember that less rock means more lava.
See you in a bit!
