Astra was a kid who dreamed of going to space. And one day, his dream came true! He put on his astronaut suit and hopped into his spaceship. 3, 2, 1...blast off! Astra was zooming through the galaxy, exploring planets and stars.

But Astra realized something important. In space, our bodies have different needs. He looked out the spaceship window and saw a beautiful, blue planet below. Astra knew it was Earth. 'Wow!' he said. 'I miss Earth's fresh air and tasty food. How can I take care of my body in space?'

Astra started to research and experiment. He found out that our bodies need air, water, food, exercise, and sleep to stay healthy. Astra had air in his spaceship and he had a suit that recycled his breath. But what about the other things?

Astra got an idea! He created a mini garden inside his spaceship. He grew plants that produced fresh oxygen so he could breathe better. He also had a special machine that turned sweat and pee into drinking water. It was like having his own water fountain!

Next, Astra focused on food. He packed lots of fruits, vegetables, and grains that provided energy. But he missed his favorite dessert - ice cream! Astra discovered how to make ice cream without a freezer. He mixed milk, sugar, and flavors, and swung it around in a special machine. In no time, he had delicious space ice cream!

Astra realized he also needed exercise to keep his muscles strong. He couldn't run or jump like on Earth, but he found a way. Astra created an anti-gravity room where he could float and do exercises. It was like having his own space gym!

Lastly, Astra knew he needed enough sleep to feel rested and energized. In his spaceship, he had a cozy sleeping pod where he rested and dreamed of new adventures.

Astra was proud of himself. He had solved the problem of taking care of his body in space. He knew that by understanding what our bodies need and finding creative solutions, we can overcome any challenge. Astra continued his journey through the galaxy, keeping himself healthy and happy.
