Additional unprocessed images gathered during Cassini's plunge are available online, along with hundreds of thousands collected by the probe during the more than 13 years it has spend studying Saturn and its moons — observations which resulted in the publication of more than 3,000 studies and such discoveries
as liquid methane seas at Titan and hydrothermal activity on Enceladus.

As you chill the
methane and oxygen below its
liquid point, you get a fairly meaningful density increase — you get on the order of 10 % to 12 % density increase, which makes quite a big difference for the propellant load.

liquid methane laps a shore of solid ice
as the biggest rainstorm ever falls from an orange sky.
Heat and catalysts converted
methane into syngas (carbon monoxide and hydrogen) which were then transformed into
liquid hydrocarbons (otherwise known
as oil and its derivatives): petroleum, gasoline and, in the case of aviation, kerosene.
About three minutes after the probe landed, it picked up a tendril of
methane wafting from the surface,
as if the probe's heat were boiling some of the
liquid trapped just below.
Titan is the only place in the solar system, besides Earth, that has large bodies of
liquid on its surface, though its seas are composed of hydrocarbons such
as methane rather than water.
She was there
as Cassini discovered lakes of
liquid methane and ethane dotting the poles of Saturn's giant moon Titan, which is larger than the planet Mercury.
Instead of water,
liquid methane falls
as rain, creates rivers that cut into the hydrocarbon - rich surface, which in turn make valleys, and flows into vast
liquid methane lakes.

liquid methane and ethane seas appear
as splotchy features near the moon's poles.

liquid such
as water and

as solid ices to agglomerate with the dust grains.
A partial list of properties surveyed includes density (expressed
as API gravity), vapor pressure, initial boiling point, boiling point distribution, flash point, gas — oil ratio, «light ends» (dissolved gases — including nitrogen, carbon dioxide, hydrogen sulfide,
methane, ethane, and propane — and butanes and other volatile
liquids) composition, and flash gas composition.
Waste energy: Municipal solid waste, landfill gas,
methane, digester gas,
liquid acetonitrile waste, tall oil, waste alcohol, medical waste, paper pellets, sludge waste, solid byproducts, tires, agricultural byproducts, closed loop biomass, fish oil, and straw used
as fuel.
When used
as a source of energy to manufacture hydrocarbons such
as methane and
liquid fuels,
as you point out solar panels can only do this in the daytime.
As recoverable oil reserves dwindle, there will be increasing pressure to convert coal to liquid fuels as well as exploit unconventional fossil fuels like methane hydrates, tar sands, and oil shal

Estimates for the global size of the CO2 utilization market by 2030 in carbonate aggregates, fuels (
methane and
liquid fuels), concrete, methanol, and polymers are
as large
as $ 700 billion, utilizing 7 billion metric tons of CO2 per year, which is equivalent to approximately 15 percent of current global CO2 emissions.
I would be rather interested in the costs of
methane to
liquid fuels (such
as the plant in Qatar), LNG for transphort (with infrastructure costs) and combined
methane / coal to
liquids.
Researchers from South Dakota School of Mines & Technology (SDSMT) are heading a project to to investigate
methane cycling in deep and extreme environments and to develop new biological routes using previously unexplored and novel microorganisms from extreme environments for converting
methane into value - added products such
as liquid biofuels, biopolymers,... Read more →
Of course, to me the ideal answer is direct solar power → Fuel, such
as methane (to replace natural gas) or
liquid hydrocarbons (to replace fossil).
