In case you’re wondering whether or not they are “qualified” to explain this, check out this video of them successfully building and launching their own mini spacecraft.  They caught the attention of NASA as well as former President Barack Obama.  I’d say the “Solar Sisters” know what they’re talking about!

WASHINGTON, DC – APRIL 13: U.S. President Barack Obama listens to sisters Kimberly Yeung (R) and Rebecca Yeung (L) explain their science project while touring exhibits at the White House Science Fair April 13, 2016 in Washington, DC. The Yeung sisters, from Seattle, Washington, built a homemade spacecraft out of archery arrows and wood scraps, and launched it into the stratosphere via a helium balloon. They named it the Loki Lego Launcher after their late cat and a Lego figurine, and it records location coordinates, temperature, velocity, and pressure and reports the data back to the young inventors on the ground.
