黑龙江省哈尔滨市第六中学2020届高三上学期英语期中考试试卷
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."
