Metro City Grand Hotel was hosting a fancy party.
All of Metro City's richest people were there.
"What a lovely party!" said a woman with a diamond necklace.
"Yes, it is," said another woman.
She had a large ruby pinned to her dress.
Suddenly there was a loud noise. Rumble! Rumble!
"I hear motorcycles," said a man.
A bolt of electricity flashed.
Zap! The lights went out.
When they came back on, everyone screamed.
"Our jewelry!" a woman cried. "Someone stole it!"
"Wow!" said Jack. "I can see Mars perfectly!"
Roxy and her friends were in Jack's backyard.
They were using Jack's new telescope.
"Can I have a turn now?" asked Mara.
"Sure," said Jack.
He stepped back and let Mara look through the telescope.
"I see Mars!" she said. "It's red and rocky!"
"Do you see any Martians?" Terrell laughed.
"Ha-ha!" Mara laughed too.
"I don't see any Martians!"
Jack opened a book about space.
"Let's try to find this galaxy next!"
He pointed to a colorful picture.
"Cool!" said Terrell.
"First we have to find it on your star chart."
Terrell unfolded the star chart.
Roxy leaned in to look.
"We need to look between those two stars," she said.
Roxy pointed to two bright stars on the chart.
"Okay," said Jack.
He spotted the two stars in the sky.
Mara turned the telescope toward the stars.
"It would be so cool to be an astronaut," she said.
"I would love to go into space in a rocket!"
"Astronauts are cool," said Terrell.
"But you know who's even cooler than an astronaut?"
"Let me guess," said Roxy. "Rocket Girl."
"Yeah!" Terrell grinned.
"An astronaut needs a rocket to fly in space.
But Rocket Girl can fly in space without one."
"Well, I think astronauts are pretty cool anyway," said Roxy.
Terrell's eyes lit up.
"Maybe Rocket Girl is flying through space right now!
We should try to find her with the telescope!"
Roxy laughed. "I don't think Rocket Girl is up there right now."
Just then her watch beeped.
She stepped away from her friends.
"Mayor Bloom," Roxy whispered. "Is there a problem?"
"Yes, Rocket Girl," said the mayor.
"There's a terrible problem!
Someone has robbed the jewelry convention!
All the jewels—diamonds, rubies, pearls—they were all stolen!"
"Don't worry, Mayor," said Roxy.
"Rocket Girl will find the thief!"
