Transcript Student Ballooning Course (SBC) Overview

Introduction to the LA ACES
Student Ballooning Course
A summary of the motivation, contents and
status of the materials available to support
implementing a student built balloon
payload program at a university or college

Motivation
• There has been little development of
classroom materials to support the
student built aerospace payload
program.
• No materials for an integrated course
– Need to cover diverse topics
– Need to complete in academic year
• Focus on younger undergraduates
– Work with ~2nd year students
• Available “CanSat” electronics needed
improvements
• Provide basis for an advanced program
Launch of the ACES-01 vehicle during May, 2003

Basic SBC Structure
• Divided into two major components
– Formal lectures and skill building activities (1st semester)
– Payload design, development and operation (2nd semester)
• Detailed structure follows that used during the ACES pilot
– Assume 14 weeks per semester
– Two required sessions per week and each session is 2 hours long
– For 1st semester each required session includes ~1 hour lecture &
~1 hour activity
– For 2nd semester students are engaged in payload development
• Students will need to complete or extend their activities
during times beyond the required sessions
• During payload development the students will need to
prepare and present reports of their status

SBC Contents
• A course syllabus
– Provides a summary of the Student Ballooning Course
– Can be modified to fit institution needs
• Lectures
– 33 PowerPoint presentations covering the primary topics relevant to
the program
• Activities
– 30 descriptions of hand-on activities that complement the lectures and
build skills relevant to payload development
• List of materials necessary for the activities
• A hardware kit with the PCBs, microcomputer and other core
components required to support the activities
• Evaluation forms
– Feedback from both students and instructors is important

SBC Hardware Components
BalloonSat includes
a Basic Stamp
microcontroller
for programming
activities. Can
also be used as
the payload
controller
SkeeterSat is an introductory
circuit assembly activity where
the output beep frequency is
temperature dependent and the
interval between beeps is light
intensity dependent
HOBO data acquisition device with
internal temperature sensor,
external temperature probe and
auxiliary input
Miscellaneous Parts includes
specialized components &
sensors used by some
activities
The SBC distribution CD also includes numerous reference documents and
specialized software

Science Unit
• Unit provides some background
knowledge on selected science
topics
• Anticipated lectures include
– Atmospheric structure &
composition
– Cosmic rays & their interaction in
the atmosphere
– Remote sensing
– Solar radiation
• Opportunity to use local faculty
expertise
• Contributions are solicited and
would be very welcome!

New for this year
• For this year we will be asking you to determine your
science payload topic within the next week or so.
• Lecture next session will provide descriptions of
potential payloads.
– All will fit within the imposed weight, power, size, budget
and time constraints
– Intention is for you to choose a payload from this list
• Free to determine your own payload, but you will need
to show that it will fit the constraints
• Think about applications to your payload while we go
through the lectures and activities this semester.
