It is the singular focus of their desperate flight toward the planet’s viscous surface, with Jackson pushing the Argo to its limits to reach it despite catastrophic risks. The Doctor insists the liquid world will cushion their fall, while the signal radiates unseen peril beneath what appears to be a hostile but navigable environment.
