Bronze Space, can't find modules?

Hi,

I'm trying to self study bronze space at home as my squadron is very slow doing the training but I cannot find the Open University modules for it? Does anyone have any information as to where I can find them to complete as I can't figure it out.
Cadet portal states you need to have completed the "Open university Exploring Space Module" and the "open University The Moon: our Nearest Neighbour Module" but I cannot find these anywhere?

If anyone has an insight it would be great appreciated.
Thanks
