From Tales Of The Unexpected No. 79, to be precise... a science fiction anthology put out by DC from 1956 to 1967.
The Space Ranger series featured a futuristic hero with a rather pointless secret identity, assisted by a blonde damsel and a shape-shifting alien who usually resembled a failed Muppet.
The first leg of their adventure finds them sinking in the spongy terrain of the planet Jupiter. (Their planet Jupiter, certainly not ours.)
Surviving that ordeal, they travel to a planet outside our solar system, where they're snared in sticky webs set up by the natives to foil intruders with Uni-Jet packs.
I could explain the rest of this goofy story, but that wouldn't be doing you any favors.
