    At just 18 years old, Canberra student Lochie Ferrier has already conducted research in a frontier field -aerospace(宇航工业) engineering. Aerospace engineering is the primary _________ of engineering concerned with the science and technology of aircraft and spacecraft.

In 2014, he was one of 80 high school students worldwide who _________ a six-week science and engineering program at MIT. During the program, he was _______ by the institute’s scientists, and developed a method to identify inactive satellites. This method, called OASIS, is designed _________ a way to help manage space debris (碎片), which _________ operating satellites. “One solution to this problem is a _________ robot that can gather pieces of space debris and store them in orbit,” he says. “These pieces could be _________ to new satellites later thus _________ the costs and launch weights of new satellites.” However, _________ satellite identification technology would be needed for this solution, and that’s what Lochie is working on. “I hope this method would be put into  ____________in the near future, saying the next 10 years,” he says.

Lochie has made the ____________ of the Young Innovators category(类别) of the Australian Innovation(创新) Challenge Awards with his OASIS. This category is open to students aged 21 years or ____________ and carries a $ 5,000 prize. If he won, he would use the money to help fund ____________ research into OASIS. “My plan for using the money would be to try to use materials which could stand up to the ____________ environment of space,” he says.

He is also considering how to ____________the technology to organizations such as NASA and satellite manufacturers.

Lochie’s____________ in aerospace engineering was aroused by the big dish antenna(碟形天线) at NASA’s tracking station near Canberra, which he visited in his early teens. He said his software design and development teacher at Canberra Grammar School ____________ him, too. “He taught me valuable project management and skills which I applied to OASIS.”

Lochie has been ____________ Canberra Grammar School and will soon sit exams for admission to universities. He ____________ his time among schoolwork, his personal ____________ projects such as OASIS and the development of apps, rock climbing, and playing classical violin. The teenager is well on his way to realizing his sky-high ambition.
