Dana and the Robot Najm on the Orbital Station

Dana and the Robot Najm on the Orbital Station

📝 Summary

In 2090 Dana lives with her engineer mother on a space station orbiting Earth, and when air leaks from the seed module and the alarm system fails, Dana uses what she has learned about pressure and oxygen, with her little robot Najm, to save the seed vault.

📖 Story

In the year 2090, four hundred kilometers above the Earth's surface, the Oasis Orbital Station circled our planet once every ninety minutes. The station was like a small city hanging in space. It had laboratories, bedrooms, a kitchen and big round windows from which its residents watched the blue Earth turning slowly below them, with its white clouds, golden deserts and shining seas. Thirty people lived there, and among them was only one child: Dana.

Dana was eleven. She had come with her mother, the engineer Layla, six months earlier, because her mother was in charge of the most important place on the station: the seed module. In this module was a cold vault holding the seeds of thousands of plants from every land on Earth: wheat, barley, rice, dates, almonds and rare flowers, kept in space so they would not be lost if a disaster happened on Earth. Her mother used to say: These seeds are the memory of the green Earth, and we must guard them.

Dana had a friend who never left her side: a small white robot the size of a football, with two glowing blue eyes and small fans that let it fly through the air inside the station, because everything there floats in weightlessness. Dana named him Najm. Najm helped her with her lessons, read her stories and played catch with her using floating water balls, which in space turn into wobbly, shining spheres. Dana would tell him: You are my little brother who does not eat my sweets.

Dana studied remotely with a class at her school on Earth, and she learned things most children only read about in books. She learned that the air in the station must stay at a certain pressure, or people cannot breathe. She learned that the doors between modules close automatically if the pressure drops in one of them, so the air does not escape from the whole station. And she learned that the most important rule in space is: do not act fast, act smart.

One night, or what they called night on the station, since the sun rises and sets sixteen times a day there, most residents were asleep in sleeping bags fixed to the walls. Dana's mother was outside the station with three engineers, wearing spacesuits and repairing a large solar panel. Dana was awake because she could not sleep, so she floated with Najm to the big window to watch the sunrise over the ocean.

Suddenly Najm said in his gentle metallic voice: Dana, I hear an unusual sound. Dana fell silent and listened, and she heard a very faint whistle coming from the corridor of the seed module. She flew with Najm toward the sound and looked at the pressure screen by the module door, and she saw the number dropping slowly, very slowly. She said: There is a small air leak! But why is the alarm not ringing? Najm said: The alarm system in this module is under maintenance tonight. Your mother switched it off before she went out.

Dana felt fear creeping into her chest. If the leak continued, the door would close automatically before long, the module would get very cold and the delicate cooling machines that protect the seeds might be damaged. She thought about screaming to wake everyone, but she remembered the rule: do not act fast, act smart. So she took a deep breath and said: Najm, call the command room and my mother right now, and tell them the number on the screen.

Najm made the call, and Commander Samer's voice came, sleepy and then alert: Dana, well done. I am coming, but I am at the other end of the station. I will need seven minutes. Then her mother's voice came from outside the station: Dana, my darling, listen carefully. The leak is small and we have time. Can you find exactly where it is? Dana said: I will try. And she thought: How can I find a hole so tiny the eye cannot see it?

Then she remembered an old lesson from the school lab: air moves from high pressure to low pressure, and air escaping through a hole pulls anything light nearby along with it. She said: Najm, do you have the vapor sprayer we use in our lesson experiments? Najm said: Yes! He opened a small door in his body, took out a sprayer and puffed a thin cloud of white vapor into the corridor. Dana saw the whole cloud floating calmly, except for one thin thread of it that was being pulled quickly toward a corner near the frame of a small window.

Dana moved closer and looked carefully, and she saw a very thin crack in the rubber seal around the window, as long as her little finger. She said: I found it, Mom! In the seal of the small window, on the left side. Her mother said: Excellent! In the red cupboard on the wall there is a box called Emergency Patch. It is like a big sticker. Peel off the cover, put it over the crack and press hard for thirty seconds. Do not be afraid. The pressure itself will help you, because it will pull the patch toward the crack.

Najm flew to the red cupboard, opened it with his little arm and took out the box. Dana held the patch in trembling hands and began to float a little, so she hooked her feet into the wall loops to keep from drifting away. Then she peeled off the cover, placed the patch over the crack and pressed with all her strength. Najm counted out loud: one, two, three... Dana felt the patch sticking, and the whistle grew fainter, then fainter still, and then stopped completely.

When Najm said: Thirty! Dana looked at the screen and saw that the number had stopped dropping. A minute later Commander Samer came flying down the corridor with a testing device. He passed it over the patch and said: The seal is completely tight. Then he switched on the backup air system, and the number slowly rose until it was back to normal. He looked at Dana and said: You saved the entire seed vault, Dana.

Dana's mother came back inside the station an hour later, took off her helmet, flew straight to her daughter and hugged her tightly. She said: I was more worried about you than about the seeds. Then she smiled and said: But you did everything right. You did not panic, you called at once and you used science to find the hole. Dana said: I was not alone. Najm was with me, and you were in my ear. Najm made a little musical sound, as if laughing with pride.

The next day the residents gathered in the big hall, and Commander Samer announced that the station would change an important rule: no alarm would be switched off for maintenance unless a backup alarm was turned on first. He said: We learned from Dana that danger can come small and quiet, and that careful observation can save a great deal. Then he gave her a small silver badge shaped like a seed, engraved on the back: Guardian of the Green Memory.

That night Dana floated with Najm to the big window and looked at the blue Earth turning beneath her, thinking of the fields of wheat, the palm groves and the orchards whose seeds the station kept safe. She said: Najm, do you know the most beautiful thing I learned today? That the science we study in class is not just words in books, but a tool to protect what we love. Najm's blue eyes glowed and he said: And that courage means thinking calmly when you are afraid. Then the sun rose over the ocean for the sixteenth time that day.
