The Story

From a high-school workbench to the space-biology record

Two slideshows from the MadWest High School rocket team's work with the AstroBotany lab β€” a hands-on gravitropism experiment under coloured light, and the full Reggies' Veggies research story that connects a student rocket launch to spaceflight transcriptomics and NASA's open data.

Gravitropism under coloured light

A short assay (summer 2016): how do roots bend with gravity under different light colours? A team member set up the camera and a spectral LED rig, then tracked root-tip angle and root length across blue, green, purple, red and white light.

Reggies' Veggies β€” the research story

The longer arc: calcium and auxin imaging of how plants sense gravity, the MadWest team building and flying their own botanical payloads, and the AstroBotany lab's spaceflight transcriptomics revealing that plants in space mount a "highlight"-like stress response β€” and why all of it belongs in one open database.

Background science shown in this deck (GCaMP calcium imaging, the TOAST / BRIC-19 spaceflight transcriptome, the "highlight" stress response) comes from the University of Wisconsin–Madison AstroBotany lab and its collaborators β€” see references. The MadWest team's own contributions are the suborbital botanical payloads and ground assays featured across this site's Results.
