Step 1: Set-up Site
Chairs and Tables Placed
Materials Organized
Step 2: Â Command Center Established
Canopy Set-Up
Tables Placed Under Canopy for Projection Team
Step 3: Balloon Inflation Site Set-Up
Tarp Spread Out
Helium Tank Placed
Step 4: Begin Inflation
Inflation Tube Attached
Valve Open
The inflation was done very slowly.
When there was enough helium in the balloon so that it would float on its own, the valve was closed.
Step 5: Initial Projections
The projection team used the tools on the Internet to predict the landing site.
The landing site was predicted to be in the center of the populated city of Frederick, MD.
A better landing site was predicted if we delayed the launch two hours.
The payload should land in a less populated location North of Frederick.
The launch time was changed from 10 am to noon.
Step 6: Loading the Payload
Each device was carefully placed in the box.
The box contained two cameras, a data collector, a battery charger, and a tracking device.
The electronics were not turned on at this point.
Step 7: Helium Calculations
After much debate, the projection team used a tool called the "Balloon Burst Calculator" to determine the amount of helium needed to land in a good location.
The amount of helium was reported to the inflation team.
Step 8: Complete Inflation
The amount of mass necessary to counter the balloon lift force was determined.
This amount of mass was placed in a bucket.
The bucket was attached to the inflation tube.
When there was enough helium in the balloon to lift the bucket, the valve on the helium tank was closed.
Step 9: Finishing the Balloon
The tying expert used her skills to tie the balloon.
The payload string was attached to a loop on the tied balloon.
Tape was used to hold all of the connections together.
Step 10: Finishing the Payload Box
The data collector was turned on.
The tracking devices were turned on.
The Internet was used to verify that the trackers were working.
The cameras were turned on.
All of the items were secured inside the box.
The box was sealed.
Step 11: The Payload Train
The sealed box was tied to the string from the balloon eighty feet away.
A cut-down device, parachute, radar reflector, and another tracking device was attached to the payload string.
All of the connections were checked.
Step 12: The Launch
The balloon was slowly released as the payload train carefully followed.
When the box reached the front of the line, it was released.
