- Every input, value and percentile: [breakdown](https://spacenexus.us/rankings/space-score-methodology?company=busek-co#breakdown)
- The Space Score is a 0 to 1000 snapshot of a space company's size and activity, relative to the other companies we track. It combines size (headcount, market value and revenue, 30%), U.S. federal space contracts (20%), equity raised (15%), momentum (15%) and, for launch companies, orbital launches (20%), so it leans heavily on size. It is descriptive: not a forecast, a rating or investment advice.
- The Space Score ranks companies relative to each other on public data we hold. It describes; it does not rate, forecast or recommend. It is not a credit rating and not investment advice.
