Robotics office still open for now, Huntsville Times
"Another problem with the lunar robotics office is that the probe had been expanded beyond its original mission, said Keith Cowing, a former NASA employee who now runs the agency watchdog Web site NASAWatch.com. "Part of this issue has always been massive cost growth," Cowing said. "It's ballooned from a $300 million to $400 million program to double. It's something around $1 billion now." Cowing said a simple lunar lander, similar to the ones put on the moon during the Apollo missions "has grown from a simple design to a battleship. It has more requirements and mission responsibility than originally planned."
Editor's note: I was referring specifically to the Surveyor series of robotic landers which were used to do in situ analysis of the lunar surface in preparation for Apollo landings a few years later.
