D. 12. Which of the following is NOT a major challenge for robotic space flight? Being able to survive extreme temperature Being able to get the robots into space Being able to communicate with Earth Being able to survive cosmic radiation

The correct answer is "Being able to get the robots into space." While launching robots into space is a logistical and engineering challenge, it is not considered a major challenge specific to robotic space flight itself. The other options—surviving extreme temperatures, communicating with Earth, and surviving cosmic radiation—are significant challenges that directly affect the design and operation of robotic spacecraft.
