BIOME III builds on this design as a free-deploying rotorcraft payload with an improved experiment bay. At apogee, it fully separates from the rocket, deploying actively using magnetic gridfins and servos to stabilize its rotation as it descends. This iteration of the payload was launched with Ringo IV/IIIB.

BIOME II (Bioaerosol Investigation of Microbial Ecosystems) is a CubeSat payload flown on Ringo III. Tethered to the rocket at apogee, it tested a rotating chamber sampling mechanism to capture particles from the troposphere for later analysis. Passive gridfins on all 4 sides stabilized the rotation of the payload to ensure a steady inlet of air through each vial.

Atlas was designed in collaboration with AlbertaSat, the University of Alberta's CubeSat engineering project team. It served as a mass model for their upcoming Ex-Alta 3 satellite. With a suite of accelerometers and strain gauges, Atlas was able to characterize the loads that will be experienced by Ex-Alta 3 during launch, and validated the structural integrity of the upcoming satellite.

Ringo II’s Payload takes inspiration from the ongoing NASA Dragonfly Mission and was the first step in a 5-year project to develop and test a deployable roto-copter drone for atmospheric and biological sampling. The first payload of this long-term project, Bioaerosol Investigation of Microbial Ecosystems (BIOME), underwent tethered deployment at apogee. While remaining tethered to the launch vehicle’s drogue chute, BIOME used an air sampling unit to filter and collect microbes from the lower troposphere for on-the-ground culturing and analysis. BIOME went on to win first place in the Payload Design Challenge at the 2023 Launch Canada Competition.

Ringo I carried a scientific payload that studied fluid flow through capillary tubes in the microgravity experienced at apogee. It aimed to determine the critical nozzle geometric parameters for spontaneously ejection of one or more droplets of water, in 100% (results from ground), and 5 to 1% of Earth’s gravity (flight apogee). It was awarded first place in the Payload Design Challenge at the inaugural 2022 Launch Canada Competition.
