Lauren Rojas, 12, strapped the doll on the flight gear that she collected from High Altitude Science and attached GoPro Hero2 video cameras to record the journey, the New York Daily News reported Saturday.
Propelled by a 43-degree weather balloon, Hello Kitty took a ride almost 18 miles above the surface of the earth stationed in a rocket.
The recorded video of the trip captures the moment when the weather balloon swells to 56 times its original size and breaks at 93,625 feet above the earth's surface.
But the rocket did not reach the ground as it got caught 50 feet above the ground in a tree, 47.5 miles from the launch sight.
Rojas, who attends Cornerstone Christian School, said that she liked Hello Kitty ever since she was six years old and thought it would be really fun to add the toy inside the rocket, which took a couple of weeks to put it all together.
She uploaded the video to YouTube on Jan. 25 where it has already been sighted more than 100,000 times.
