TV5 transfer Minmus to Ike Refuels with single land and launch, Transits from Ike adjusting to Duna low polar orbit Lab and 5 x Rovers are landed at the Duna Outpost Prime Mover Duna Space Bus (skycrane) and Space Ark rendezvous with Duna Space Station Prime Mover docks with 10 seat module and Large fuel tank, creating the Advances Duna Space Transit Vehicle (ADST) Architectural Notes: The ADST with 1 large tanks has a dV of about 5000m/s , and so has plenty of fuel for a transit to Kerbin and back. The Rovers each have 2 Cuppola pressured seats, and 8 command seats in a Mk2 enclosure. The DSB is capable of "hopping" a Rover to any location on Duna and return to the Outpost. At Year 10, there are 100 Kerbals on the surface, and fully self sustaining. An additional 2 Kerbals arrived with Transit Vehicle 5 The Duna Space Station has room for 3 Kerbals long term and a lab, plus a 100 seat Space Ark capable of returning all Kerbals to Kerbin There are 3 Emergency Ascent Vehicles at the Outpost, with a total of 102 command seats. Each is capable of reaching orbit, and rendezvous with the Space Arc.

How else are they going to operate mining equipment in the darkness of polar craters? Mirrors? I don't think so.

A total of 100 Kerbals on Duna. Architectural notes: By using Duna Space Bus and components on return from Duna, and 5 launches from the KSC, Transit Vehicle 4 is so far the largest TV in this architecture, transporting 44 Kerbals. Due to KSP part count limitations, expansion of the existing outpost is not possible, so a new outpost is constructed 350m form the original site

DOMA Redux. 56 Kerbals in a self sustaining habitat on Duna.

Only 4 launches from the KSC limits the size of this transit vehicle and therefore the number of Kerbals that can be transferred.

I wonder if the Dragon XL might have flexible hoses that could be man-handled by the crew through the ports across the HALO to the PPE and lander. Hypergolics too toxic?

Mars 2020 in Real Solar System. The emphasis is on dimensional accuracy, with all components similar in size, mass and performance to the real world (<+/-10% variance).

Thanks, I will be assuming direct entry. I tried using a piston, but it made the Descent stage and Rover assembly too tall. Clipping it caused all kinds of unwanted explosions and disassembly during decoupling. So I came up with another means of mimicking the cable lowering system on the descent stage

Does anybody know the planned approach to Mars? I have just completed the launch and transit, and now arriving at Mars, I have some options on how to do this. I had been assuming that the craft simply entered the atmosphere and then lands directly, with a rather violent aerobrake from an entry speed of around 5600 m/s. But i If I was NASA, I would choose for the craft to skim the upper atmosphere slowing down into a roughly circular orbit, then adjust to ensure more accurate positioning for the landing. This has the advantage of placing less stress on the hear shield, with final entry speed of around 4100 m/s, however I am not sure if the cruise stage was designed to remain attached during aerobraking manoeuvres

I tried using the KAL-1000, but alas the RPM would not rise above 480, no matter what I did. What's more, the kraken awoke, eventually the blades would fly off in all directions. Then I figured it out. The Ingenuity is 2kg total mass IRL. The answer was to mod the part config files, making the part mass roughly equivalent to real world. Set torque = 5, and main throttle linked to RPM control. Success!

Below is my Ingenuity on Mars. Flies brilliantly on Duna, but apparently in RSS, the Martian atmosphere is too thin for the stock parts. Not surprising really, the Ingenuity IRL requires the blades to rotate at 2400 rpm, and for KSP the max is 460 rpm. I tried hacking the part files, but can't find a way to increase the rpm or lift parameters. Looks my RSS mission will not be including Ingenuity. :(

I would be really keen to have a go at this in RSS but will only do if Tweakscale is approved so I can mimic the mission more accurately. Confirm Y/N. Edit: Noted, it's in the OP as allowed so, Woohoo I am in! An idea I had to make this more interesting is to mimic the sample collection with an ore container, and develop a second mission to collect the sample and return it to Earth.

Do you mean something like this?

Ahhh, a thud powered flying rover. That makes sense.

Yes, I leave the DSBs extra two seats in orbit for most of the assembly to increase efficiency, and then add the 2 seat module to create the DSB after outpost assembly is completed. I don't have a proper rover deployed yet - driving a rover around this area must have been a real challenge.

The radiation environment could be easily simulated on Earth, and the epidemiological studies on radiation exposure have been done. It is extended stay in high radiation plus zero G that is unique. Testing radiation protection clothing?

Building a big outpost at Duna's North Pole. 32 Kerbals, fully sustainable using greenhouses and algae farms.

Crew transfer. 29 Kerbals on the way to Duna.

In my original mission, I launched from the KSC all life support supplied to Duna, which is the intent of the challenge. And I kept 100 Kerbals in my outpost alive, and had enough supplies left to bring them all home after the 10 year mission. My current mission uses USI-LS, which requires a very complex (and heavy) system of greenhouses and algae farms and power supply, and water as well as ore drilling, in order to create a sustainable outpost. It is not as efficient as carrying supplies from the KSC, I am expecting to only support 50-70 Kerbals but I am working hard at improving this number. Allow Kerbals to eat monoprop? Sounds like free food to me. My two cents worth. Thanks. Actually I had forgotten that Launch 8 occurs before Jeb returns to Kerbin, so I could have launched a pod to return to him and Val and the samples to the KSC safely. But good news they can now return safely in the crew shuttle - I had designed the shuttle specifically for both launching and returning crew from orbit so happy I can use the craft as designed.

Since Jeb has collected 5 biome samples, and is now on his way back to Kerbin, this question has me a bit concerned. The rules state: "only crew may be launched on these missions; no fuel or any other supplies may be transferred on crew launches. ". I had not interpreted that as disallowing biome samples to be carried on the crew shuttle from orbit to the KSC, because (a) samples are not fuel or resources, and (b) the rule says nothing about transferring "to" or "via" the shuttle for return to the KSC. I await DM's adjudication with trepidation. Jeb may yet die horribly in a flaming wreck in a vain attempt to re-enter the atmosphere in an unsuitable craft. Perhaps this is an option? I mean there is no transfer of anything, is there?
