Sisters called to White House

A pair of young Seattle sisters who sent a balloon to the edge of space are be received at the White House 

Last September, Rebecca, 10, and Kimberly, 8, went out to Moses Lake with their parents to launch a spacecraft they designed and built. 

We built a spacecraft that was attached to a weather balloon and parachute,. We launched it in Central Washington. We took it to the edge of space, 78,000 feet up. It’s called the Loki Lego Launcher 1, or L-Cubed-1, because Loki was our cat. Lego because every time we launch we want to send up a different Lego mini figure.
— Rebecca Yeung, 10

Both girls say they took on the project because they love science, in part because of a really great science teacher they have at Seattle Country Day School. But their father, licenced Amateur Radio Operator Winston Yeung KI7CSK, was another motivating force. 

Kimberly and Rebecca hope to show other children that science and engineering is not only interesting and accessible for kids, but a lot of fun as well,
— Amanda Stone, White House Senior Program Manager

The sisters hoped to launch the APRS equipped spacecraft again during their spring break, but the voyage has been postponed until after their trip to D.C.
