Space Exploration

[Caecilian]

Though, I still think that we should first investigate the oceans a bit further, since we haven't seen the deepest ends of it.

That is dangerous! We might find R'ley and wake sleeping Cthulu.

So what if we do?

But Johansen had not given out yet. Knowing that the Thing could surely overtake the Alert until steam was fully up, he resolved on a desperate chance; and, setting the engine for full speed, ran lightning-like on deck and reversed the wheel. There was a mighty eddying and foaming in the noisome brine, and as the steam mounted higher and higher the brave Norwegian drove his vessel head on against the pursuing jelly which rose above the unclean froth like the stern of a daemon galleon. The awful squid-head with writhing feelers came nearly up to the bowsprit of the sturdy yacht, but johansen drove on relentlessly. There was a bursting as of an exploding bladder, a slushy nastiness as of a cloven sunfish, a stench as of a thousand opened graves, and a sound that the chronicler could not put on paper. For an instant the ship was befouled by an acrid and blinding green cloud, and then there was only a venomous seething astern; where - God in heaven! - the scattered plasticity of that nameless sky-spawn was nebulously recombining in its hateful original form, whilst its distance widened every second as the Alert gained impetus from its mounting steam.
From: The Call of Cthuhlu by HP Lovecraft

Cthuhlu is a wuss. He gets beaten up by an old steamship. He'd have no chance against modern weaponry.
