NASA has decided to exempt its Mars probe, MAVEN, from the government shutdown, allowing preparations to resume for its November launch.

NASA Headquarters in Washington determined that Maven’s preparations should go ahead on an emergency basis — not because of its scientific objectives, but because of its expected role as a communications relay satellite for the Opportunity and Curiosity rovers on Mars. “Both Mars Reconnaissance Orbiter and Odyssey have been acting as communication relays, but they’ve passed their design lifetime,” Jakosky explained. “Maven carries communication equipment to take over that job as necessary. Getting us launched at this opportunity is a way to preserve that ability to communicate.”

As I’ve said before, as much as I am in favor of launching this kind of science mission, the number of arbitrary decisions relating to this shutdown makes the whole thing look ridiculous. NASA can act to protect its investments on Mars, but the National Park Service is required to interfere with the normal actions of private restaurants here on Earth?

The truth is that these science missions really don’t fall under the intended definition of “essential operations”. The federal bureaucracy, under the direction of the White House, is simply stretching that definition for their own convenience, wherever they like.
