"Horizons" is billed as a season of five expansions, starting with planetary landings and then followed with a more comprehensive looting and crafting system released in May 2016, ship-launched fighters and passenger missions released in October 2016, and support for multiple players working cooperatively on the same ship planned for a future expansion within the first half of 2017 ahead of PlayStation 4 release and with a 5th expansion to follow after that. The 2nd, 3rd and 4th expansions were announced originally for spring, summer and autumn 2016 respectively. But the 5th expansion had no reference to "winter", was not time-scheduled and had no content description, only stating a cryptic "soon" reference. The ability to walk around and the types of worlds players can land on is expected to be expanded during upcoming seasons, with landing on planets with atmospheres or earthlike worlds not being part of the "Horizons" season, but due at a later stage.
