Weather Balloon Time

How are we going to get it into space?How are we going to get it safely back down?How are we going to find it when it lands?

Laws

• Entire weight of all payloads cannot exceed 12 lb in total weight (Excludes weight of balloon).

• No payload package can exceed 6 lb in weight.

• Payloads cannot exceed a package weight/size ratio of three ounces per square inch.

• Cell Phones are not permitted to track high-altitude weather balloons in flight.

• No rope or cable should be used which requires more than 50lb of force to separate payload packages from balloon.

• No one may launch a high-altitude weather balloon which creates a hazard to other people and property. (i.e. Incorrect parachute, faulty rigging, inappropriate launch location)

• No one may use a high-altitude weather balloon to drop objects (i.e. gliders and projectiles).

Geocaching

A worldwide treasure hunt!

Objects are hidden around the world waiting to be found…but there are no maps!

So how do we find them?

GPS!!

Global Positioning System

Uses satellites to get coordinates that tell us where something/someone is located on Earth.

Coordinates

N/S E/W

The Atmosphere

Wind Speed

What does this mean for our balloon?
