Drag Racing Cubesats with the NASA CubeQuest Challenge
December 23, 2016
In this edition of the PhysicsCentral podcast, we hear from a few teams who are still in the running for the CubeQuest Challenge: a contest for homegrown teams to build their own small satellites - cubesats - and compete against each other by demonstrating technological feats. Five million dollars in prize money will be divided among teams who can get into orbit around the moon, maintain a stable orbit for a long time, or make it almost all the way to Mars' orbit while still communicating with Earth.

Spectra's Energetic Escape

Out Now: Spectra's Energetic Escape!

PhysicsQuest: "Spectra's Energetic Escape!" has shipped!

Did you miss your chance to get the free kit, but still want to follow Spectra's adventures—and explore all the fun experiments that go along with Spectra's Energetic Escape? You can find the comic, along with the teacher's manual edition, on the PhysicsQuest page!

The students at Tesla Junior High are thrilled to hear that their favorite magazine, Fetch, has selected their school to be profiled in their upcoming issue. There's just one twist—they aren't profiling the whole school, just a select 16 that will be competing in 24 hours of challenges to win tickets to see the latest, hottest boy band, the Free Radicals! 

As usual, however, things don't go as planned. Your students will learn about energy and motion while they help their favorite middle school students escape the accidental catastrophe caused by Nolan R. Gibbs (N.R.G.), the editor in chief of Fetch. Learn about energy transfer in pendulums, making a potential energy powered pinwheel, energy and friction, and bouncy ball rockets! See who makes it to the concert...or even makes it out alive!

If you'd like to download past manuals or comics and create your own kits, that can be done through links on the About PhysicsQuest page.
