Answer :
We can actually deduce here that the astronaut that raised his hand actually said that the colour of the feather placed on his helmet was blue and going further to give a logical explanation, he explained that this is because the sky of the planet where they are is blue.
What is logical explanation?
Logical explanation actually refers to the explanation that is given using logic and what everyone sees and knows. In logical reasoning, one speaks based on what he/she knows or acquires from reasoning or thinking through.
We see here that logically thinking, the helmet placed on their heads actually denoted sky and the blue feather denotes the colour of the sky. Remember they were told not to look up. That means what we are looking for is up which is the sky.
Thus, we can say here that the colour of the feather placed on his helmet is blue and it actually talks about the colour of their planet.
