A walk-in oven for curing large composite pieces arrived this week at Carnegie Mellon's Planetary Robotics Lab. The oven is especially useful for the pieces that will make up the spacecraft-lander that delivers our robot to the lunar surface. The oven's floor includes two grooves for the wheels of the support cart that will hold large pieces in the 350-degree curing phase. The oven also will be used, at lower temperatures, for determining the highest operational temperature of batteries and electronic components.
