A book is cited for some of the material on the page.  That book is not cheap.  To buy it new is 200 bucks.  A used one is about 120.  Too rich for my blood.

Interesting quote that I will lift off this page:

In fact, transport class rocket ships working routes in orbital space can have mass proportions not far different from transport aircraft flying the longest nonstop global routes.

A jetliner taking off on a maximum-range flight may carry 40 percent of its total weight in fuel, with 45 percent for the plane itself and 15 percent in payload. A moonship, the one that gets you to lunar orbit, might be 60 percent propellant on departure from low Earth orbit, with 25 percent for the spacecraft and the same 15 percent payload. The lander that takes you to the lunar surface and back gets away with 55 percent propellant, 25 percent for the spacecraft, and 20 percent payload.

(These figures are for hydrogen and oxygen as propellants, currently somewhat out of favor because liquid hydrogen is bulky, hard to work with, and boils away so readily. But H2-O2 is the best performer, and may be available on the Moon if lunar ice appears in concentrations that can be shoveled into a hopper. Increase propellant load by about half for kerosene and oxygen, or 'storable' propellants.)

The boil-off problem, with hydrogen as propellant, may be minimized if the propellant is stored in a cold place. A place like the LaGrange points could work for this purpose.

Now I found it.  It looks like a bit more delta-v than Mars.  If you can get to Mars, you should be able to get to Ceres and back to Mars.  Don't know about launch windows or such.  By the way, this kind of thing is going to take a lot of time, or a lot of energy.  If it is a lot of energy, then nuclear looks like the most likely thing.  However, that may be a lot easier said than done.


original post:

Many years ago, I came across this thing.  If you want to travel through the solar system, you need to know the delta-v requirements.  I am not educated enough to know how to calculate these things, but luckily someone else is, and we have a nice little table to look at, and use it to ponder over the possibilities.

I was looking for delta v for a mission to Ceres from Mars.  So far, I haven't found it.
