MISSION OVERVIEW
 The objective of team Up Up and Away is to prove the possibility
and efficacy of a balloon mounted mechanism for cloud seeding
 Cloud seeding has never been attempted from a balloon mounted
device
 Could prove the feasibility and possible cost effectiveness
 Given the ability to use enough of the correct substance for cloud
seeding, a balloon mounted mechanism will be feasible and
economic
 Cloud seeding can lift droughts and increase precipitation. A
cheaper alternative to traditional methods can reveal further
opportunities

Objective 1.0
Team Up Up and Away will prove the possibility and
efficiency of a balloon-mounted mechanism for
cloud seeding.
Team Up Up and away will test the effectiveness and
reliability of the funnel dispersing system of the
BalloonSat.
B.O.S.S will collect the data of outside, inside
temperature, humidity, pressure, and the speed of
wind during the flight.
The integrated GoPro camera in B.O.S.S will record
the flight and also the cloud seeding process.

Requirement
Derived from
Objective 1.1
Team Up Up and away will prove that given the ability to use
enough of the correct substance for cloud seeding, a balloon
mounted mechanism will be feasible and economic.
Objective 1.0
Objective 2.1
Using the two integrated funnels and servos, the BalloonSat will
disperse Sodium Chloride at two different altitudes.
Objective 2.0
Objective 2.2
The mechanism to release the powder will consist of an oscillating
triangular aluminum plate controlled by a Servo, which will block
the flow of salt out of the container except when prompted to move.
Objective 2.0
Objective 2.3
The base plate on which the oscillating plate will rest will also be
made out of a 3mm thick aluminum sheet and will assure that the
triangular piece can oscillate smoothly against its surface.
Objective 2.0
Objective 2.4
The funnel will be supported by cross wires so that it does not fall
over or get shaken or broken in flight. We will make sure that the
salt will not fall out of the cone by securing a lid on the top of it.
Objective 2.0
Objective 3.1
With the GoPro facing down, it will attempt to capture the process
of cloud seeding.
Using the arduino and the sensors, the BalloonSat will record the
data for temperature, humidity, pressure, and wind speed during the
duration of the flight.

EXPECTED RESULTS
 We Expect To:
 Record accurate information from all sensors
 Confirm the proper functioning of mechanisms (namely the servos)
 Observe the powder as it is released
 We Hope To:
 Observe (with GoPro and from ground) a red cloud forming after
powder is released
 This observation would confirm both function and effectiveness of our
release system
