To unlock space you must have repaired Eden, reached Civilization level 2 (built 20 levels worth of wonders) and built all 3 eden Airships. You need to research the tech that allows you to "activate eden" (In the Tech Hall - resource tab), once you've done that you will be able to enter the initial sector in space.
To be able to explore the first sector, you will need to set up your Airships for each of the four Factions worth of Gumballs at the same time. You can also add Robots and Clones to improve your total energy. Your energy will be significantly lower than in the Sky until you've done sufficient research. The 5th research tab which makes this possible is unlocked in the first space sector, M01.
Eden will be shown on your map as a blue crosshair 
.
Travel between sectors can be done once you have obtained the sky map, and found a space transition device. Currently there is a limited supply of these, but more sources for them are expected to be added to the game later.
Sectors
The initial release for space brings one sector, M02 is expected to arrive September 2018, and more are expected later in 2018 and beyond.
Each sector is divided into a 9x9 grid with subsectors, which must be cleared of their Fog of War. You can only clear one every few minutes, but you will find items in space to reduce this cooldown. The fifth Research tab will also reduce the fog of war cooldown timer.
Order Domain
All order sectors are noted by the "M" at the front of the name. The Space map will allow you to view and travel between different order (and chaos) fields.
