Lunokhod 1 was a Soviet lunar rover launched on November 10, 1970. It was carried to the Moon by the Luna 17 lander, which was launched atop a Proton rocket. On November 17 Luna 17 touched down on the Moon and released onto the surface Lunokhod 1, which became the first roving vehicle to land on another world.

Description

Built in KSP v1.9.1
A stock replica of the Proton-K/D rocket and its payload: Lunokhod 1.
Includes the Luna 17 lander which features stock folding ramps.
Lunokhod sports an updated radiator design and a deployable solar lid. It also includes a new low-profile communotron hinge courtesy of Majorjim!.

Controls

4: Lander RCS toggle (off by default)
5: Lander vernier toggle (off by default)

Instructions

Flying the Proton is pretty straightforward, but for the best looking flight I’d recommend following the stage timings written in the description.

Activate the Luna lander’s RCS system after stage 4. Turn on the lander’s verniers when maneuvering with the main engine and landing.

3/15/20 Update: The Proton has been updated for better usability.

The second stage of the Proton has been rebuilt with less fairings to cut down on drag. The amount of fuel in the first three stages has been reduced, as well as engine power. This was done to lower the rocket’s total delta-v, to make the rocket better suited for launching into low Kerbin orbit. Stage timings have been rewritten accordingly.

Flight Profile

Press the brake button on the HUD to lock the rover’s wheels before flight.

T+0s (0:00) Stage once to start stage 1. Throttle up and stage again to release launch clamps.

Start your gravity turn, the rocket should hit 45 degrees at about 15000m.

T+88s (1:28) Stage 2 Ignition.

Stage 1 will separate automatically

T+93s (1:33) Interstage jettison.

Once your apoapsis hits 90km, start pitching down towards radial-in. Adjust your pitch to keep the apoapsis at 80km.

T+177s (2:57) Stage 3 ullage motor start.

T+180s (3:00) Stage 2 separation.

T+183s (3:03) Stage 3 main engine ignition.

T+190s (3:10) Fairing jettsion.

Circularize the orbit by burning between prograde and radial-in. Shift towards radial-in to draw the apoapsis lower and closer to your own. Then shift towards prograde to circularize.

Once in orbit, throttle down and stage once to separate stage 3.

Press R to activate stage 4 RCS control, and stage to ignite stage 4. Perform a circularization burn if necessary.

Plot and perform a trans-munar injection. Aim for a periapsis of 50-100km above the Mun.

Press G to extend the landing gear and stage to separate the lander from stage 4. Press 4 to activate the lander’s RCS system.

Once at the Mun, use the lander’s main engine to enter a circular orbit. Press 5 to toggle the lander’s verniers for better control during maneuvers.

Make another burn to bring the periapsis 15km or lower over the landing site. Stage to jettison the auxiliary fuel tanks.

At T-1:00 to periapsis, start burning retrograde to begin the landing. Leave the verniers on throughout the landing sequence.

Point the lander between the retrograde vector and the horizon. Stop the burn once velocity has been reduced to 50m/s and let the lander fall to ~2500m over the surface.

Throttle up again to slow down and stage to activate additional verniers to assist in the landing.
