A bespoke powerpoint theme

I want to create a theme or backgrounds for a powerpoint presentation I am giving soon.

I have a brand that you can see at

All the images come from the Nasa central archive that is public domain. You would be free to use the images from the site or use other ones from the archive. It's important that the backgrounds don't take over from the content.

We should use the Balanced logo, colour schemes and fonts from the site,
