Making peace with US Air Force and dropping charges against the agency has paid off for SpaceX. Its Falcon 9 rocket has finally been certified, giving the company the right to compete for national security launches. Elon Musk's space corp has passed every requirement set by the Air Force, after a couple of years (and a few months of delay), lots of paperwork and tests. According to Air Force Secretary Deborah Lee James, this certification allows more than one provider to compete for military launches, which is expected to cost the branch $70 billion until 2030, for the first time in around a decade. "Ultimately, leverage of the commercial space market drives down cost to the American taxpayer and improves our military's resiliency," she said in a statement.
