	'''Project Cycloon''' ({{slack-channel\|balloons-cycloon}}) is a core project on SSI's [[Balloons]] team with the aim of designing and operating altitude-controlled, long-endurance, aero-marine balloon platforms for tropical cyclone research. Begun in January 2019, Cycloon has launched five payloads as of August 2019 and has deployed proof-of-concepts of several novel techniques in high-altitude ballooning, as well as giving rise to [[HABSIM]]. Please contact the current ~~co-leads~~ of Cycloon, {{slack-user\|~~bjing}} and {{slack~~-~~user~~\|~~jtang~~}}, to get involved!
