Sev­eral is­sues caused the de­lay, no­tably the sun­shield tak­ing longer than planned to assem­ble and leaks in the propul­sion sys­tem. “Con­sid­er­ing the in­vest­ment, we want to pro­ceed sys­tem­at­i­cally through these last tests with the ad­di­tional time nec­es­sary,” says Thomas Zur­buchen, as­so­ciate ad­min­is­tra­tor for NASA’s Science Mis­sion Direc­torate.
