"It will not be we who reach Alpha Centauri, and the other nearby stars, it will be a species very like us, but with more of our strengths and fewer of our weaknesses, more confident, far-seeing, capable, and prudent. For all our failings, despite our limitations and fallibilities, we humans are capable of greatness."-Carl Sagan
In the Flood it is said that the ODST play their anthem. Nothing is touched upon regarding it since, but that got me thinking.
What if this is the actual anthem
The very song used in the live action trailer.
