Whiz-kid sisters launch homemade craft to get a glimpse of space
They haven’t even touched their teen years and these two sisters already know more about space and astronomy than you would know. Meet Kimberly and Rebecca Yeung aged 8 and 10 who have a passion for space science, and they proved it alright by launching their homemade craft to the edge of Earth’s atmosphere, almost reaching 78,000 feet with a top speed of 110 km/h. That height apparently is achieved by a commercial aircraft carrier and it in itself is a great achievement when you consider their age!
They made a triangular craft called Loki Lego Launcher and attached it to a helium balloon. Made from wood and broken arrows, the rig also had two GoPro cameras on-board to record the action and a flight computer to collect all the data. And if you are wondering why the craft is named “Loki Lego Launcher”, well because Loki is their cat and they have put a Lego R2D2 besides it.
This craft equipped with GoPro cameras reached a distance of 78,000 and recorded all the flight data on-board
The craft traveled for over four hours and twenty minutes before coming down on the ground and for the most part of its journey had a smooth ride before the balloon popped. Thanks to the GPS tracker on-board, the girls were able to find the spacecraft in a thick grass field with Loki and R2D2 being detached from the craft upon impact and resting on the grass not far away. From the launch site in Stratford, WA, they had to go 50 miles north to get the aircraft when it came tumbling down to the ground.
These intelligent sisters have learned a lot from their project and I’m sure they’ll be making another one which is much improved in design and who knows it might go even further to reveal the magnificence of space!
