On this Δv map, the total to reach low orbit of Sarnus from Kerbin’s surface is ~28,980 m/s (≈ 29 km/s) — that’s the number printed under “Sarnus”.
Useful baselines (same map logic):
- From low Kerbin orbit (LKO): ~28,980 − 3,400 ≈ 25,580 m/s
- From Kerbin escape: ~28,980 − (3,400 + 950) ≈ 24,630 m/s
Notes the map is implicitly screaming:
- That’s vacuum Δv and doesn’t include plane-change Δv.
- If you aerobrake in Sarnus’s atmosphere (or do clever gravity assists), your required capture Δv can drop a lot compared to the map’s brute-force number.
