Solid vs liquid fuel

See the table at this link.

I could not copy the table without losing the format.

Overall, the liquid fuel system is more likely to fail.

Great, I will reproduce the table here:

Solid-fuel advantages	Solid-fuel disadvantages	Liquid-fuel advantages	Liquid-fuel disadvantages
Very stable, durable	Can't be turned off- once the burn starts, it goes until fuel is used up.	Variable thrust- the amount of fuel and rate of burn can be changed in flight	Fragile, many complex parts
More thrust for a similar size rocket	Fuel decomposes, must be replaced.	Liquid-fuel boosters are more easily re-usable	Oxidiser (liquid oxygen) must be kept extremely cold.
