There are so many load screens in Starfield. The worst offender being the aspects around ships. Loading screen to get into the ship, Loading screen to launch into space (you don't actually fly into space). Loading screen to then fast travel to destination. Loading screen to then land on a planet. Loading screen to then exit your ship. Since you landed right next to an outpost you will walk a few feet only to have another loading screen to enter the building.
None of the loading seems too long, but the sheer quantity kills immersion. I honestly don't know what I expected from a Bethesda RPG with the creation engine.
