This thread is my log of @Scarecrow71s real-world Historical Space Race challenge My plan is to play both the Soviet and US. I am doing sandbox mode, with the focus on the craft being accurate replicas of the original craft in terms of appearance and function. KSP Version: 1.12.2 DLC: Both (Making History and Breaking Ground) Mods KER MechJeb 2 EVE Scatterer Trajectories Tweakscale Restock Restock Plus RealPlume KW Rocketry Rebalanced I may add more mods later, but liking the challenge of stock+tweakscale. I added KW Rocketry to get a Apollo petal adapter and decouplers.

I know, I'll start a mission report and put together a video for each achievement. Edit: I have decided to make a few minor changes, I cannot decide which engine to use for the verniers. Twitch, Spider or Cub? I tested with the Cub -looks correct in terms of size against the Kodiak (RL-107/108). But too much thrust? Also will reduce the payload size to match the IRL sizing of the warhead.

R-7 Semyorka ICBM Complete with retracting service towers. Achieves 100km orbit with a 5t payload.

Thanks. I think I will go Stock Parts/Modded with KER and MJ. Doing this massive challenge without informational and automation mods is a bridge too far. Edit: I might go modded with Tweakscale, it helps with creating replicas with limited parts at the right scale. Is that allowed?

@Scarecrow71 I am keen to do this in sandbox mode, and stock + DLC, unmodded. Just to be clear, KER and Mechjeb are not OK in the unmodded category?

I used USI-LS, but didn't use "deepfreeze", and was unaware of such a capability. FYI I launched with just enough fertilizer and solar power for the greenhouse(s) to generate sufficient supplies for the Duna Transit.

Jinnantonix Duna One Level 3 - Mission Update: Phase 3 of the challenge is completed with 4 Kerbals returned to Kerbin from Duna.

Jinnantonix Duna One Level 3 - Mission Update: Phase 2 of the challenge is completed with 12 additional Kerbals on the surface of Duna. The craft includes two greenhouses, fully sustainable. Payload Costs

Jinnantonix Duna One Level 3 - Mission Update: Phase 1 of the challenge is completed with 4 Kerbals on the surface of Duna. The craft includes a greenhouse deployment which is fully sustainable by mining ore and converting to fertiliser, and the greenhouse converting fertiliser and mulch into bland but nutritious NOMs , continuous supplies for the 4 Kerbals. Payload costs:

For each launch, after Stage 1 separation, I follow Stage 2. The Stage 1 chutes are deployed at the moment of Stage 1 separation, so will deploy automatically. As the video shows, the first stage lands safely under chutes alone.

Jinnantonix Duna One Level 3 - Mission Update: Standard launch vehicle for each of the ten launches is completed. The design is similar to the Ares 1. https://en.wikipedia.org/wiki/Ares_I The LV can handle a payload of 25 tons to LKO (100 km altitude). Stage 1 is a SRB, and stage 2 is LF/Ox. Both stages are fully recoverable. Kerbals will be launched in an Escape Pod which can eject if there is a rocket failure. The Escape Pod is also fully recoverable. Costs are: LV Stage 1: Wet = K$ 25900. Dry = K$ 16060 LV Stage 2: Wet = K$ 11991. Dry = K$ 10522 Escape Pod: Wet = K$ 10563. Dry = K$ 10526 So in addition to the payload, the cost of each launch is K$ 11309, plus $K37 if the escape pod is used. SO the maximum payload cost is K$ 88564.

So Level 3 needs to be done without KER or Trajectories? Why? Life support is hard enough, surely!

Thanks for the challenge @jimmymcgoochie

If informational mods are allowed, I assume Trajectories is OK? I propose a standard launch vehicle comprising a SRB first stage and a LF+Ox second stage which takes the payload to LOE. Is it OK if both are recoverable? Do I recover the full cost, minus fuel? Is it allowed to deploy a greenhouse in Phase One to support the initial 4 Kerbonauts?

Level 3 looks like a real challenge, especially in establishing a sustainable greenhouse. There's a trick to powering that beast, right? Questions: Is re-usability of the launch vehicle allowed? If so, what rules around recovery cost? Can all three phases be launched through a single Hohmann transfer window, as a single craft? If KER or Mechjeb is used, would it be considered a modded entry?

I am amazed that nobody else has taken this on. Although it required some time and commitment, it's the most fun challenge I have completed to date.

Something like this? Note: All stock.

The fundamental idea behind this is to use a scaled down model (relatively easy) to validate the best architecture for post Artemis missions that use fuel manufacture on the moon. JNSQ would be fun, but obviously more challenging than stock, and would not really add anything. Having said that, go for it!

Definitely. They can be used for both the space station and the Duna Habitat, but ... "Crew cabins and lander cans may not be occupied while in atmospheric flight".

You could do it, but the leaderboard is for stock + DLC only. I have added a Rogues Gallery so you may be included.

Yes, looks good. 1. Your probe for the Mun should be a simple marker with resource scanner, and land PRIOR to to the ISRU facility. The intention is to find the resource and a landing zone prior to landing an expensive asset. 2. Looks like you are using the Duna Habitat to provide the 8 seats for the space station. It is within the rules.

I don't see anything wrong with the strategy. I think it follows closely that Artemis proposed framework very closely, so kinda disappointed you wont be actually doing it. i am pretty sure at some stage I will do a RSS simulation, and I expect it will be near identical to your architecture.

1. Yes that is allowed. 2. 8 seats are required on the Space Station and the Duna Habitat,. The return craft requires 4 seats. 3. Yes, allowed.
