Source-backed presentation
Read the actual evidence.
Every graph keeps its complete axes. Select a subject or enlarge a figure to read the labels. No smoothed replacement curves or invented observations.
Altitude and flight sequence
The authored 2026 figure marks burst at 82,497 ft after about 61 minutes. This is the report’s correct image, not the old 2025 cache also present in the document.

Vertical velocity
The report annotates 63.6 mph descent and approximately 15.1 mph final velocity. These are source annotations, not an independently verified touchdown measurement.

Acceleration and recovery
The source labels a 6.2 G burst jolt, a second 5.7 G jolt and a 4 G parachute event. A temporary shutdown interrupts the record; no continuous interpolation is implied.

Published flight trajectory
The team’s authored map marks an 82,497 ft maximum. It is a presentation image, not a downloadable coordinate track.

Asymmetric balloon burst
The original camera frame records the asymmetric balloon opening. Visual evidence of the burst is not a new measurement reconstructed from video.

Flight-train motion
The source image illustrates helical response of the flight train. Perspective alone does not establish a calibrated rotation rate.

External temperature versus altitude
Prose states −66.5 °C; retained chart values reach −67.99 °C. The difference is disclosed instead of replacing one with the other.

Pressure versus altitude
Prose states 49.2 Torr minimum; retained chart values reach 49.429 Torr. This is the report’s altitude channel, not synchronized APRS altitude.

Relative humidity on the recorder clock
The source uses elapsed seconds horizontally, not altitude. It marks approximately 72% RH near 1,687 ft during descent. Do not align this clock with another recorder without synchronization.

UVA channel versus altitude
The source averages four side-mounted sensors. These channels are not established as calibrated irradiance; noise and shutdown/recovery remain visible.

UVB channel versus altitude
This sensor channel is not a UV index or dose measurement. Its numerical scale is not interchangeable with other UV channels.

UVC channel versus altitude
Nonzero UVC channel response does not establish ambient UVC exposure. Spectral response, cross-sensitivity and calibration need review.

CO₂ channel versus altitude
Retained chart values peak at 939 ppm near 77,483 ft, with an earlier peak of 623 ppm near 10,879 ft. These are reported sensor readings; pressure compensation and calibration are not established. Altitude association does not establish cause.

Radiation profile on the recorder clock
Although the source title says “versus altitude,” its horizontal axis is recorder time in seconds. Annotations identify a profile maximum near 63,300 ft and burst at 82,497 ft. Counts per minute are not a radiation dose.

Enlarge figure →Source notes that matter.
- The first three native chart caches contain Fall 2025 values. This page uses the correct Spring 2026 authored image overlays instead.
- Recorders use different clocks and altitude channels. Independent peaks are not time-aligned observations.
- Signed “windspeed” calculations are not shown as physical speed magnitudes because their sign convention is unestablished.
Source: team-supplied “Spring 2026 launch acquired data” report and photographed presentation boards. Student research, not independent instrument certification. Detector counts are not dose; channel output is not automatically calibrated concentration or irradiance.
