Mousetronaut Goes to Mars
Page 1
The Galaxy Rocket was just one week away from launching.
It would be the first human mission to Mars. Even though Mars was Earth’s neighbor, the astronauts would need to travel more than 35 million miles to get there.
And Meteor the Mousetronaut couldn’t wait to go!
The astronauts had been training for two years for this trip.
Meteor watched everything they did. Each day he
looked over the astronauts’ shoulders as they studied, sat under the table and listened while they ate, and kept a notebook of the flight plan and procedures.
Meteor was certain that he’d be going to Mars too.
He might not be the biggest astronaut, but he had the power of small.
But when the names of the crew were called out, Meteor’s name wasn’t one of them.
He worked hard to stay in shape.
The Mousetronaut was not on the list.
He ran with Claudia.

could hide. He would STOW AWAY!
Slowly, carefully, he climbed the launch tower.
Then, when the NASA security guard wasn’t looking,
he hid under the commander’s seat.
He tried to be as quiet as he could, but he was scared.
He wasn’t scared of the rocket launch. He was scared that he would be caught.
The rocket shook. Meteor was pushed against the floor. He held on tight so he wouldn’t slide out from under the seat. There was a lot of vibration. Much more than he remembered from his launch on the space shuttle, but not enough to bother a Mousetronaut.
Nine minutes later they were in space. Meteor loved the feeling of weightlessness.
During the long journey, Meteor stayed hidden.
He would only come out for crumbs when the astronauts slept.
And as Earth got

grew bigger.
After six months they finally arrived.
Meteor had stayed hidden the entire time.
When no one was looking, Meteor peeked through the
window and saw different shades
of red and orange.
Mars was nothing like Earth, but it was still
beautiful in its own way.
He also heard the astronauts making plans.
Two of them would go down to the surface
and explore Mars on foot and with a rover.
But there was a problem.
Galaxy’s commander was talking to mission control in Houston.
One of the landing craft’s engines had failed its test and wouldn’t work.
The remaining engine wasn’t strong enough to carry even one astronaut.
There would be no trip to the surface of the red planet.
They would need to turn around and return to Earth.
But the Moustronaut had an idea.
He shot out of his hiding place to the surprise
of the crew.
“Meteor! Where were you hiding?” the
commander asked.
They were happy to see him, but still sad
about their failed mission.
Then Meteor floated over to the hatch
leading to the landing craft.
“Hmm. It is possible,” said the
commander. “One rocket engine
could work for someone small
enough.”
It was decided. Meteor the Mousetronaut would
be the first to set foot on Mars.
As he put on his spacesuit, the crew gave
him instructions.
“You need to gather plenty of rock samples,” said one.
“And don’t forget to bring back some soil,” added another.
Last of all, they made a tiny American flag and fastened it to a straw.
Meteor tied himself into the seat of the landing craft with some string.
It launched from the Galaxy spacecraft and made its way to the surface of Mars.
The Martian landscape was unlike anything
Meteor had seen before. There were no plants.
There was no water that he could see. But most
important, there were NO CATS!
But he got right to work gathering the samples.
The last thing he did before reboarding the land-
ing craft was to plant the tiny flag he’d been given.
“Meteor, you saved the day.” The crew cheered him as he returned to the ship.
“You’ll be in newspaper headlines around the world!”
The Mousetronaut felt very proud.
“And we’ll make sure you are on our next mission!”
Six months later Galaxy Rocket returned to Earth.
The astronauts were all welcomed as heroes.
But the smallest among them was the biggest hero of all.
The first successful flight to Mars was made by NASA’s (2012). Plus there are three orbiters ( Mars Odyssey, Mars Mariner 4 on a flyby mission. It flew by Mars in July 1965, 228
