Descend close to a planet’s surface (switches to 8K when near)
M
Destinations list
V
Sky in ultraviolet ↔ visible light
T
Time (real time → 1 hour/s → 1 day/s → 30 days/s)
P
Pause / resume time
G
Back to Earth
L
Mouse flight (pointer lock, Esc to exit)
Mobile
Bottom-left joystick = fly (push past the ring to boost) · drag right side = look · pinch out/in = forward/back · ▲▼ = up/down · tap the name of what's in the center circle = autopilot · tap = info
Flight speed changes automatically with the distance to the nearest object: slow near planets, light-years per second between the stars.

About a third of the map (mostly the galactic plane) is predicted from other wavelengths rather than observed.
