Time, system, and bodies

Time

Path	Format	Meaning
time/ut	seconds	universal simulation time
time/warp	scalar	current warp factor; 1 is realtime
time/sim_dt	seconds	last simulation advance; 0 is effectively paused
time/warp_speeds	f f …	discrete game warp factors
time/auto_warp	0 or 1 target-ut	automatic warp state and target
time/alarm	seconds	write a target UT; its read blocks until that time

time/alarm is the simulation-clock sleep primitive. It is warp-correct, unlike sleeping for wall time. HTTP offers the same wait as GET /v1/time/wait?until=<ut>.

System and bodies

system/{name,home,sun} and bodies/<id>/ exist when telemetry_bodies=true. Body catalogs update at telemetry_bodies_rate_hz, or every sample when it is zero.

Group	Leaves	Units / caveat
identity	id, class, parent, children	children is a newline list
physical	mass, radius, mu, soi, rotation_rate	kg, m, m³/s², m, rad/s
motion	position/ecl, velocity/ecl	ECL m and m/s
orbit	apoapsis, periapsis, ecc, inc, lan, argpe, sma, period	apses are altitude in m; angles are degrees
atmosphere	present, height, scale_height, sea_level_pressure, sea_level_density	absent for airless bodies
ocean	present, density	absent without an ocean

bodies/<id>/focus is a trigger: write 1 to move the main camera to the body. It is view-only and does not require vessel-control authority. For coordinate meanings, use Frames and units.
