Greetings Space Explorers!

A long-awaited new Major Update #2 has just been released! This build introduces all the newly announced features along with many tweaks and fixes!

NEW FEATURES:

  • added Space Stations with their respective research

  • instant free drag-and-drop transfers of modules and resources from orbit to surface, between orbiting bodies, or, in some cases, surface to orbit (space elevators, Electromagnetic Catapults)

  • added a possibility to save and load mission presets

  • shift + click for auto-creation of missions with missing resources to planned orbital constructions (requires resources on the parent body surface)

  • added constant acceleration flights to cyclical missions

  • added an option to take fuel for return flights for cyclical missions

  • planning construction without resources

Changes:

  • added a minimum fuel marker to the fuel slider

  • added orbit highlight for drag and drop

  • new tooltips

  • current/required resources value for ideal atmospheric pressure

  • communication satellites income in tooltip/info panel

  • space elevator contract adjustments

  • added filtering by deposits in search window

  • fuel production balance - nerfed to follow the law of mass action and produce extra oxygen

  • major objects panel and objects in info panel header adjustment

  • faster save loading/creation

  • building orbital construction in orbit now requires orbital construction

  • origin/target in mission window clickable

  • search window text input field focused automatically after opening it

  • changed visual button for switching to parent body

  • notifications, when mined deposit depletes/changes

  • scrapping space station and interstellar before it's fully built

  • displaying up to 3 notifications at once without opening notifications

  • orbital habitats name and description changed to differentiate from space stations

  • added construction time in SC info panel

Fixes:

  • cancelling a facility construction causing resource duplication

  • duplicating object panel after scrapping a facility/module/SC/LV

  • cyclical mission not using fastest preset correctly

  • possibility to cancel construction of other corporations’ facilities and modules

  • improved clickability of (Orbit) label on models of objects

  • pop-up background styles could look different

  • you couldn't produce orbital spacecraft on an asteroid in orbit

  • spacecraft construction module disappearing

  • you couldn't scrap multiple SC/LVs

  • facilities with power storage keep working when disabled

  • fuel cost could not display for some LV combination with orbital payload container

  • radioisotope generators stopped working

  • facilities showing drag and drop info in tooltips

  • comm sat natural growth bonus issues

  • removed interstellar ship fake orbit

  • facilities’ background flickering due to energy calculations

  • energy production/usage not synced with production cycle

  • camera spinning very fast with comet on objects' orbits

  • atlas not using hydrogen to pull asteroids

  • space station ghost of modules visible after canceling stacked construction

  • construction in orbit stopped if an asteroid fell from orbit to object

  • radioisotope generators existing in saves stopped working 

  • orbital payload container could require fuel

  • autobuying resources didn't check if they're on market

  • you could scrap a facility not meant for scrapping

  • atmospheric composition now displays properly

  • orbital construction/telescope sent to orbit via instant transfer didn't work in orbit

  • failed mission draining fuel

  • ability to create broken cyclical mission

  • space station mounted modules count could be exceeded

  • facility/module panel during construction would not update properly

  • you could open Trappist panel from Earth

  • you could open bugged marketplace

Known issues:

  • unclear communication of the auto-mission to orbit feature

  • cargo delivered to orbital spacecraft from the surface might exceed the LV capabilities

  • some of the translated texts might be inaccurate

  • minimum fuel marker can disappear

  • fuel cost tooltip may show the same info twice

  • orbit drag-and-drop can sometimes remain visible 

  • AI using space station modules as normal modules

  • population growth can be high

  • comm sats incorrectly show population growth multiplier (total multiplier on tooltip for humans shown correctly)

  • you can drop modules/resources on planets for which mission planning is not possible

  • AL-Ice LV cost is different in info panel

  • CNSA doesn't have cyclical missions on The Expansion or later

  • spacecraft can show up with a delay after completing a mission

  • gravity assist can remove spacecraft if continuing with only a part of the fleet

  • Phobos carbon completes with any cyclical mission

  • crew compartments duplication with orbital payload container/EMC

  • editing offer in marketplace can show incorrect data

  • constant acceleration in interstellar is not available instantly

  • space station/interstellar cannot be accessed in solar orbit

  • interstellar won't work for other corporations

Thank you for your ongoing support. We hope that this update will bring you tons of fun! We strongly encourage you to fill in the new in-game survey! You can access it from the FEEDBACK button in the main menu, or >>HERE<<.

See you in space!
