This is the BBQ rub recipe that NASA used to prepare brisket for the last Space Shuttle mission, STS-135 in July 2011. They released this recipe on the NASA website. The original NASA recipe was a formula expressed in percentage of each ingredient used (by weight, similar to a baker's formula). It has been converted to volume measurements for home use. Recipe makes 1 pound = about 2 1/2 cups BBQ rub. Use at least 1 Tbsp of rub per 1 pound of meat.
