The combination of Titan’s low gravity and thick atmosphere
would allow a human to fly by strapping “fake wings” to their
arms. The second-largest moon in the solar system, Saturn’s
Titan is the only moon with a substantial atmosphere, which is
much deeper than Earth’s. It’s so thick and the gravity so weak,
in fact, that you could strap wings on your arms and flap them
like a bird to fly. The air is mostly nitrogen, but the rest is
mostly hydrocarbons, giving Titan’s atmosphere a thick orange
smoggy haze that is opaque to visible light. Cassini studies
Titan in infrared light (which can penetrate the haze) and with
radar — and in 2004, via the Huygens Probe, an atmosphere probe
became the first spacecraft to transmit from the surface of a
moon other than our own. Titan is remarkably earthlike, apart
from being so cold that water is as hard as rock; in addition to
the atmosphere, it is the only place other than Earth known to
have bodies of liquid on the surface — lakes as large as the
Great Lakes, except tha
