Key projects being undertaken within Cycloon (and their respective Slack channels) include:

*'''Altitude control:''' Cycloon aims to master and extend the legacy of altitude control on latex balloons pioneered by previous SSI projects. This entails both mechanical and algorithmic aspects.

*'''Altitude control:''' Cycloon aims to master and extend the legacy of altitude control on latex balloons pioneered by previous SSI projects. This entails both mechanical and algorithmic aspects. Design and production of the primary vent and ballast mechanisms is undertaken in {{slack-channel|balloons-cy-platform}}.

*'''Marine tether:''' In order to extend the flight endurance beyond the inherent limitations of latex, Cycloon is developing an tether and floater to rest on the surface of the ocean for days at a time. This architecture was successfully demonstrated in [[SSI-83|CY-1]].

*'''Simulations:''' The need to predict trajectories from California to the Pacific and Atlantic topical basins using the GEFS forecast ensemble has given rise to [[HABSIM]] and its associated work. See also {{slack-channel|balloons-cy-sims}}.

*'''ZPB:''' Polyethylene envelopes have intrinsically more desirable properties compared to latex envelopes. In-house manufacture of such envelopes is being explored in {{slack-channel|balloons-cy-zpb}} and was first demonstrated in [[SSI-90|CY-4]].
