The impact probe on the first page- I tried building one but it doesn't have any delta v.

- (1) 62.5 cm Thermal rocket nozzle

- (1) 62.5 cm "safe-1500" fission reactor

- (1) 62.5 cm electric generator

- (1) 62.5 cm inline radiator

- (1) Probodyne OKTO

- plus all the science and comms stuff

It won't ignite, says 'flame out- liquid fuel deprived'. I didn't see any liquid fuel in the picture. What am I missing.

Put an actual liquid fuel tank on it - the idea here is the reactor heats up whatever reaction mass you give it, causing it to expand and spray out the nozzle, instead of having to use oxidizer. The lighter the molecules, the higher the exhaust speed, the more ISP you get. Liquid Fuel is assumed to be hydrogen, so it'll get you the highest possible ISP.

What's the deal with the white nuclear reactors? They're quite obviously tilted by several degrees, making for some unsightly and difficult to balance craft. Is there a fix around?

Just landed an ISRU Refinery on Duna - the radial kind of course. Linked it up to the rest of my little settlement's power grid, and it extracted water just fine. However, electrolysis yields no liquid fuel or oxidizer. I've used KAS to connect it, and it seems to be drawing power just fine, and I made sure there is an LFO tank in the grid. So, what can I do do actually refuel my science return craft?
