There has been a lot of talk of NASA putting a Lunar Gateway in a Near Rectilinear Halo orbit around the moon, but I don't actually know how much delta-v it takes to get there. Most delta-v maps I can find have the delta-v for a lunar transfer orbit burn (about 3.2 km/s from Low Earth Orbit) and the delta-v for breaking into Low Lunar Orbit from the transfer burn (about 0.82 km/s), but I don't know how much it takes to go from the transfer orbit to a Near Rectilinear Halo orbit. I assume it takes less that Low Lunar Orbit, but how much less?
The delta-v from LEO to NRHO is 3.95 km/s.
The flight time is 5.33 days with an impulsive departure from LEO at 3.124 km/s and an NRHO capture impulse of 0.829 km/s.
