It's almost midnight and can't make a tidier presentation, like Desdinova's.
Here's the awards and decorations of the Solar League (WIP):
They include one device I made (the four-point star) and a post-Ribbon Maker Photoshop spiffing in one case, to make it stand out.
Crimson Star (2 versions I'm deciding between): wounded in combat (possibly associated to ship suffering internal damage or surviving ship destruction)
Distinguished Service Star: lesser combat-related award
Marine medals (names pending): combat drops and ship capture milestones
Meritorious/Outstanding/Superior Service: time serving the Solar League
Order of Columbus: discovery of a habitable world
Order of Magellan (1st and 2nd Class): discovery of star systems
Order of Sol: highest military honor of the Solar League
Planetary Combat Service (2 levels): ground unit tonnage destruction
Solar Navy Cross: greater combat-related award
Space Combat Service (2 levels): military shipping tonnage destruction
Probably need to brainstorm a couple of scientific award lines (one for research and the other for xenoarchaeology) and a handful of civilian merit decorations.
EDIT: For inspiration you generally don't need to look further than Wikipedia. for instance the
awards and decorations of the United States Armed Forces. From there, you can also browse the decorations of various countries and use multiple sources to create something original.
