Most of this is from memory, watching live streams. Also, some sources contradict each other, so this is my best guess.
T-0:35:00: RP-1 fuel loading begins on both stages.
T-0:35:00: Liquid oxygen (LOX) oxidizer loading begins on stage 1.
T-0:31:00: Liquid oxygen (LOX) oxidizer loading finished on stage 1.
T-0:16:00: Liquid oxygen (LOX) oxidizer loading ...

From Tons of Water in Asteroids Could Fuel Satellites, Space Exploration:
But asteroids will certainly be more accessible than the moon, another potential source of space-based water-rich minerals. According to Rivkin, landing safely on the lunar surface takes more than a hundred times the change of velocity required to land on an asteroid. Similarly, ...

The only reason near-Earth asteroids still have water is that it's bound up in hydrated minerals where it's become part of the crystal structure of those minerals. Freeing it from those minerals requires baking it out of at high temperatures (up to around 500 °C), the most easily extractable volatile ices are all long gone due to heat from the sun. In ...

Apparently, at least one OTRAG rocket test used diesel. OTRAG's intended fuel was kerosene with a nitric acid/$N_2O_4$ blend for oxidizer, so I would guess they used a similar oxidizer with diesel.
Most large rocket engines pass the fuel through tubes surrounding the combustion chamber for cooling; normal kerosene and other common hydrocarbon fuels tend to &...
