A home science experiment recently took
the world by storm. Two teens from Toronto, in Canada, sent a Lego man
rising above the Earth and captured their tiny astronaut's trip on film.
Mathew Ho and Asad Muhammad, both
17, used a weather balloon to launch their plastic lego model 16 miles above
the Earth. This is inside a part of Earth's atmosphere.
The two teens were inspired by a
similar project performed by students at the Massachusetts Institute of
Technology(MIT). The MIT students had launched a weather balloon with a camera
into near space and taken many unusual images of the Earth. Mathew and Asad
then spend four months figuring out how to launch their own spacecraft into the
space.
Travelling to space is
expensive for NASA, but Mathew and Asad worked hard to keep their costs down.
They bought much of their equipment used and even sewed the Lego man's
parachute by hand. In total, the project cost only$400.
"We had a lot of anxiety
on launch day because there were high winds when we were going up," Mathew
told reporters. They had to pump extra helium(氦)into the balloon so that it
would rise quickly and avoid being blown too far off course by the strong
winds.
The toy astronaut's journey
lasted 97 minutes before the balloon broke and he fell back to Earth. Mathew
and Asad then spent two weekends looking for their spacecraft. It had landed
76miles away from the launch site.
The student scientists are
currently finishing up their final year of high school and applying for
colleges. They are also looking into more do-it-yourself space projects.
"I guess the sky is not
really the limit anymore," Mathew told reporters. "We never knew we'd
get this far. It's been a lesson for us that hard work pays off."
