The partial government shutdown that shuttered NASA continues with no end in sight. The U.S. space program sits idle, the vast majority of its workforce sent home. Space science and exploration projects are disrupted. Paychecks are absent. And an unsettling realization has dawned on hundreds of thousands of public employees and contractors affected by the shutdown: this time is different.
