Mission Overview• Objectives:

– Measure gamma radiation during ascent• Expecting to discover ionizing radiation increases as a

function of altitude

– Measure air quality during ascent• Expecting air to have fewer dust particles

– Record HD video • Spike interest of younger students in math, science, and

engineering

• Why?– Public outreach– Verify that atmosphere is necessary for radiation

dampening

Design Overview

Results and Analysis

Arduino One (environmental data) functioned perfectly

Arduino Two (experimental data) had complete failure

GoPro camera functioned perfectly

Heater subsystem functioned perfectly

Canon camera functioned perfectly

Accelerometer

Failure Analysis

ARDUINO TWO

Needed more power

Moved from one 9V to three 9V

Connected leads incorrectly

Arduino became corrupted

Conclusions Temperature:

0-10km: Decreases 10km to 20km: Constant20km to 30 km: Increase

Pressure:Ascent: DecreasesDescent: Increases

AccelerationSome G-Forces as flight initially stabilizesConstant during main ascentLarge G-Forces after burst

Geiger Counter & Dust Sensor Inconclusive due to corrupted Arduino

GO Pro video was helpful and interesting in outreach

Ready to Fly Again

No structural modification/replacement

Two new Arduino Unos and SD cards

New Geiger Counter and Dust Sensor

All environmental sensors still functional

New batteries

Lessons LearnedOverall, Gateway to Space was an incredible

learning experience despite our failures.

Small details are vital. Our mission failed because of a simple misconnection.

Learned time management the hard way. If we could do things over, our schedule would be revamped.

We also would have contacted faculty who aided us earlier in the semester.
