Hi, we're here from Curiosity.com to help you get smarter in just a few minutes.

I'm Cody Gough.

And I'm Ashley Hamer.

Today you'll learn about an upcoming solar sale launch to test solar propulsion,

why the tongue map you learned about in school is all wrong, and new

research that says debating politics online may not be a total waste.

Let's satisfy some curiosity.

We are launching a solar sail to test solar propulsion and solar sales could pave the way for low-cost long-lasting spacecraft

As reported by Universe Today, the Planetary Society has set a June 22nd launch date for their

Light Sail 2 cube sat. Light Sail 2 is a test mission designed to study the feasibility

of using sunlight for propulsion. The small satellite will use

the pressure of sunlight on its solar sails to propel its way to a higher orbit.

The Light Sail 2 is hitching a ride inside a Georgia Tech mission called Prox 1, which itself is a secondary

payload aboard a Falcon Heavy rocket.

Light Sail 2 will be deployed in an altitude of 447 miles or 720 kilometers where the force from the

sunlight is enough to overcome the atmospheric drag. Once it's been deployed,

Light Sale 2 will take a few days to perform health and status checks, and then it'll deploy its solar panels.

About a day after that, it'll unfurl its 4 Mylar sales, which are each about the size of a boxing ring. Lateaid sail too will rely on what's called solar radiation pressure for propulsion.

Photons from the sun will push on the sails and produce a tiny amount of acceleration.

Eventually the pressure from all these photons

will raise the spacecraft's orbit.

The force is really small,
