Vesania Awakened

Vesania's chambers want 16U/s for 30 seconds. The engine asks for Graphene: Graphite + Hydrazine in the Chemistry Lab, and Hydrazine is 2 Ammonium + 1 Hydrogen - Vesania's atmosphere has the richest Hydrogen in the system, so the planet supplies everything it demands. Make the Graphene before the descent, then the usual triptych two-step at the core.
