Two weeks ago, NASA announced it’s next Discovery class mission, those low cost missions that focus on answering one question. The agency chose the InSight mission to Mars. In the press conference, the agency cited the mission’s low cost and relatively low risk as the rationale behind its selection. But this sparked a weird backlash. NASA didn’t exactly say why the mission was more likely to fly under its $425 million cost cap, and some news outlets in the days following the announcement suggested that there were hidden costs in a mission.
