What are flags?

[Pecan]

Probably a totally dumb newb question but then a) I am, and the only really stupid question is the one you don't ask.

I have seen people talking about the display of flags and see the toggle for them in the tracking station but I don't see any 'flag' parts in the VAB/SPH and can't find any information about using/planting them. How do you access flags?

You get them from EVA'd Kerbals. Right click on them, and you should see an option. You can also right-click on placed flags in EVA to remove them.

There is no part for flags, you get an unlimited supply of them for free.

To choose the flag for your mission (if you don't want to use the one you selected when you created your game) click the flag icon to the right of your spaceship name.

To plant a flag you'll need a kerbal and solid ground. Get your kerbal and right click on him. You'll see a Plant Flag option with a [1] which means he is carrying 1 flag with him. Once you click the button he will plant the flag and then a window will appear to let you add a title and description.

If you want to plant another flag you'll notice that your kerbal has 0 and can't do it. You'll either need to get another kerbal, or walk your kerbal back to a spaceship and get him to board it. He will automatically take a fresh flag from the infinite supply stored in the ship (probably in the same compartment where the EVA jetpack fuel is).
