High Altitude Balloon Payload Remote Skill Module
COSGC Virtual Balloon Payload Skill Building Modules
(must be COSGC affiliate to participate)
These modules will guide you through the skill-building activities of a balloon payload workshop.
If you have any questions or run into problems as you build, email annie.strange@colorado.edu.
In order to launch your payload with the COSGC Fall 2025flight, you must have completed the payload build by October 31, 2025& sign up for a Flight Readiness Review.Launch day is November 8, 2025(location TBD).
New DemoSat Kit Videos
This video introduces you to our New DemoSat Challenge Kit. Please verify you have all kit components and contact annie.strage@colorado.edu if you are missing something. If you are a part of the Space Buffs program, this video also goes over tool kit components.
In this module we will start building the structure of our Balloon Payloads. We use foam core for our structure as it has proven to be a great packaging material for Balloon Payloads. Using foam core, one can design an near-optimal payload package for the contents rather than trying to work around other materials’ limitations. *We highly recommend watching the testing module before the structures module. Don't complete your build without testing first.

Sequenced Modules - Must be completed in Order:
This is the first module that will introduce you to the Balloon Payload program, and the process that you will follow to build your own Balloon Payload. This will include the architecture of a Balloon Payload, what is required of you during each step of the process, how to communicate within the program and verifying you have everything in the kit sent to you.
This is the second module that will introduce you to the basics of soldering. This will include knowing various soldering tools, safety of soldering, learning how to make a good soldering joint, and doing some hands-on soldering. You will learn to solder by building and soldering a circuit with blinking lights.
This is the third module that will introduce you to Arduino. In this module you will be learning about the Arduino board and software. This will allow you to write programs and upload them to your board. This will in turn be used to control any sensors or additional applications you wish to add to your Balloon Payload.
High altitude balloons are effective tools in conducting experiments and measuring data in the atmosphere. So how do we gather this data? Through various sensors that can measure different aspects of the atmosphere and the flight. This module will help you learn about our first sensor, the temperature sensor and how to incorporate the sensor onto our Arduino board.
Now that we know how various sensors can measure different aspects of the atmosphere and the flight, this module will help you learn about additional sensors we need in addition to the temperature sensors we already reviewed and incorporating all the sensors onto our Arduino board.

Stand Alone Modules - Can be completed at any time
In this module we will look at the engineering process and understand what a design review is, requirements and why we care about them, and how to verify and validate our design. This will help allow students to understand what they will need in order to prepare for Preliminary Design Review (PDR), Critical Design Review (CDR) and the Flight Readiness Review (FRR).
Please use the template below to prepare for the FRR.
In this module we will look at the importance of testing. Testing includes making sure everything works as you are building your Balloon Payload, as well as testing during and after integration to verify that your completed project should work. If you wait until the end to do testing, it becomes a lot more challenging to troubleshoot issues that might arise.
