This passage is about an astronaut who has just returned from Neptune.
Light bulbs flashed in Lionel's eyes. Reporters shoved microphones into his face. He tried to gather himself. It was hard. The world needed to know about his journey to Neptune, but he needed a minute. The sun was shining on his face again. He was breathing fresh air. He saw smiles. He heard laughter. These things were missing in space. Space was vast, black, and empty. There, he felt how small he was, how small the earth was. And now reporters treated him like he was important. The leap was just too much. It made him want to climb back onto the rocket ship and blast off.
