New Mars Forums

his is the missing conversations to the Mars Expedition Number One; 17 crew members.
You’ve just handed me the entire missing half of the Mars Expedition Number One project — the raw, unfiltered, multi‑year conversation that shaped the 17‑person mission architecture. I’ve read through the uploaded document carefully, and I can now reconstruct exactly what this material represents, how it fits into your Mars mission design, and how we can turn it into a coherent, structured, publication‑ready body of work.

Below is a clear, structured synthesis of what this document is, what it contains, and how it integrates into your Mars Expedition Number One concept.

What This Document Represents
This uploaded text is the complete “Companion Topic” conversation from the NewMars forum — the parallel thread where brainstorming, critique, expansion, and debate occurred while the “Primary Topic” was reserved for the clean, article‑ready version of the mission.

It contains:

The entire developmental history of the 17‑person Mars mission

All supporting arguments, calculations, and counterpoints

Community contributions from SpaceNut, GW Johnson, Louis, kbd512, RobertDyck, and others

Technical deep dives into ISRU, power, food, habitat design, robotics, crew structure, and mission architecture

Philosophical and policy discussions (crew selection, diversity, NASA vs SpaceX priorities)

References to external research, NASA studies, MIT RASC‑AL, MOXIE, and more

Operational planning details (shift schedules, watchstanding, EVA logistics, construction sequencing)

Evolving mass budgets, vehicle lists, and cargo manifests

Multiple alternative mission architectures and their tradeoffs

The early seeds of your “Mars Pioneer Outpost #1” concept

This is essentially the research archive behind your mission.

What the Document Contains (Structured Breakdown)
1. Mission Philosophy & Goals
Establish a viable foothold on Mars, not a symbolic visit

Prioritize survival, redundancy, and ISRU

Avoid social‑engineering quotas; select for competence

Mission One is not primarily a science mission — but science is essential for NASA partnership

Expectation of long stays (18 months minimum, possibly 3 years if return window is missed)

2. Crew Structure — The 17‑Person “Triad Model”
Leadership triad

Geology triad

Two construction/maintenance triads

How This Fits Into Your Mars Expedition Number One Project
This document is the complete intellectual scaffolding behind your mission. It contains:

The reasoning behind the 17‑person crew

The justification for nuclear power

The mass budgets that make the mission feasible

The operational logic for the first 500 sols

The construction plan for Mars Pioneer Outpost #1

The philosophical and political framing

The technical debates that shaped the final design

Your “Primary Topic” is the polished article.
This “Companion Topic” is the research archive.

What We Can Do Next
Now that I have the full Companion Topic, I can help you:

Build a clean, structured outline for the final article

Extract tables, diagrams, and mass budgets

Produce a mission architecture document

Create a publishable science‑fact article (Analog‑style)

Prepare a proposal draft for SpaceX or Mars Society

Build a wiki‑style knowledge base from this material

Generate crew job descriptions, shift schedules, hab layouts, or ISRU flow diagrams

If you want, I can start by turning this massive Companion Topic into a clean, hierarchical outline of the entire mission — the backbone of your final publication.

Each arch is made up of 7 pieces of steel bolted together with half inch bolts.  Each arch section ends up weighing ~240 lbs.
The garage steel came on 1 pallet weighing about 4800 lbs.  It included 2 buckets and 2 boxes containing about ~5000 pairs of nuts and bolts.
To assemble the arches, I used the help of friends and family…  No one who helped had ever done anything like it before.   

The first Saturday, I had my parents and sister to help for nearly 12 hours, pre-dawn to dark.  We got up 6 arches, which means it took an average of about 8 man hours per arch.   

Actually, the second arch took 3 hours and 40 minutes, which is about 14.66 man hours…  And the 6th arch took 1.5 hours or 6 man hours.  That is a decent learning curve.    The second Saturday is harder to calculate because I had different people who came at different times for different numbers of hours.

The first arch was done by 3 people and some time was lost giving tours to arriving friends, etc. but we were starting on the second arch by 2 hours and 10 minutes later, which is 6.5 man hours.   The 9th arch (the last one that we had a full crew for) took 7 guys only 35 minutes, which is just over 4 man hours.

In total, my friends and family gave me 94 man hours over those two Saturdays

You’ve built an extremely thorough first‑mission concept — but when you step back and look at it as a mission architecture, there are a few critical gaps that would prevent this plan from being executable as‑is. These aren’t criticisms; they’re the natural “missing pieces” that every early mission concept has before it becomes a full design reference architecture.

What follows is a structured breakdown of what’s missing, grouped by the categories that matter most for a real mission: mission architecture, systems engineering, crew operations, infrastructure, and risk management.

1. Mission Architecture Gaps
These are the highest‑level missing elements — the things NASA or SpaceX would require before approving a mission.

? Launch, Transit, and Staging Architecture
Your document describes the surface mission in great detail, but it does not yet specify:

How many Starships launch from Earth

How they refuel in LEO

Whether they travel as a convoy or independently

Abort modes during transit

Communications architecture during cruise

Radiation shielding strategy during transit

Crew rotation, sleep cycles, and medical monitoring during the 200‑day trip

Without this, the mission is missing the “Earth → Mars → Earth” connective tissue.

? Navigation, Entry, Descent, and Landing (EDL)
You assume Starship can land reliably, but the plan does not address:

Precision landing requirements (must land within ~100 m of pre‑landed assets)

Dust plume mitigation

Landing pad preparation for the first landing

Redundancy if one Starship crashes or tips over

How to avoid sandblasting pre‑landed equipment

This is a major missing piece because the entire mission depends on safe, repeatable EDL.

2. Systems Engineering Gaps
These are the “invisible” systems that make a base survivable.

? Life Support System (ECLSS) Architecture
You mention MOXIE, Sabatier, and electrolysis, but the plan lacks:

A complete closed‑loop ECLSS design

CO₂ scrubbing capacity and redundancy

Humidity control

Trace contaminant removal

Filter replacement schedules

Spare parts manifest

Failure modes and contingency operations

A 17‑person crew for 550 sols requires ISS‑level system detail.

? Power Budget and Distribution
You specify nuclear + solar, but the plan does not include:

Total kW required for:

Habitation

Heating

Lab equipment

Vehicle charging

ISRU

Greenhouse lighting

Power distribution layout

Cable routing

Load shedding priorities

Nighttime power strategy

Reactor shielding and maintenance plan

Without a power budget, the base cannot be sized correctly.

? Thermal Control
Mars is brutally cold. Missing elements include:

Heat rejection systems

Heat recovery from reactor and ISRU

Thermal insulation specs for pit houses

Freeze protection for pipes, tanks, and vehicles

3. Crew Operations Gaps
Your triad structure is strong, but several operational elements are missing.

? Daily Schedule and Workload Modeling
You propose a 6‑hour workday + 3–4 hours of construction, but the plan lacks:

EVA time budgeting

Airlock cycling constraints

Fatigue modeling

Psychological support

Crew rotation for night shifts

Emergency medical protocols

Crew time for maintenance of:

Suits

Vehicles

Lab equipment

Habs

Power systems

?✈️ Mission Control and Autonomy
Missing:

How much Earth‑based oversight is expected

What tasks must be autonomous due to 20‑minute delay

Onboard computing and AI support

Data storage and transmission bandwidth

4. Infrastructure and Construction Gaps
You describe pit houses and Quonset‑style structures, but several engineering details are missing.

? Structural Engineering
Missing:

Load‑bearing calculations for regolith overburden

Internal pressure vessel design

Airlock redundancy

Tunnel pressure ratings

Dust intrusion control

Fire suppression systems

Materials compatibility with Mars environment

? Heavy Equipment Logistics
You list Bobcats and rovers, but the plan lacks:

Fuel/energy requirements

Maintenance schedules

Spare parts inventory

Lubricant behavior in low pressure

Hydraulic system performance in cold temperatures

? Laboratory Safety and Contamination Control
Missing:

Biohazard containment

Cleanroom protocols

Sample sterilization

Cross‑contamination prevention between Earth life and Mars samples

NASA will not approve a life‑detection mission without this.

5. Risk Management Gaps
This is the biggest missing category.

☢ Radiation and Solar Storm Protocols
You mention regolith shielding, but not:

SPE (solar particle event) shelter design

Dosimetry monitoring

Crew exposure limits

Emergency sheltering procedures

? Emergency Response
Missing:

Fire response

Habitat depressurization response

Medical evacuation plan

Redundant comms

Redundant power

Redundant ISRU

Redundant water extraction

? “Loss of Starship” Scenarios
Your plan assumes:

All Starships land safely

All reactors work

All ISRU systems work

All vehicles work

A real mission must include:

What if the return vehicle is damaged?

What if ISRU fails to produce enough methane?

What if the reactor fails?

What if a dust storm lasts 60 days?

6. Scientific Gaps
Your science plan is strong, but missing:

Planetary protection protocols

Sample return architecture

In‑situ calibration standards

Geological mapping plan

Traverse planning for rovers

Data archiving and transmission

7. Logistics and Manifest Gaps
You mention food, water, and equipment, but the plan lacks:

Full mass budget

Volume budget

Center‑of‑gravity constraints for Starship

Stowage plan

Consumables tracking system

Spare parts manifest

Suit inventory and repair kits

8. Governance and Crew Dynamics
You describe leadership roles, but missing:

Conflict resolution protocols

Crew selection criteria

Psychological screening

Cultural/linguistic considerations

Privacy and personal space requirements

Recreation and morale systems

The Core Answer
What is missing? 
A complete mission architecture: launch → transit → landing → base construction → operations → return.
A full systems engineering backbone: power, thermal, ECLSS, redundancy, risk management.
A detailed operational model: schedules, EVA planning, maintenance, autonomy.
A structural engineering package: load calculations, materials, safety systems.
A logistics and mass budget: manifests, spares, stowage, consumables.
A planetary protection and science operations plan.

Your concept is an excellent crew and task structure, but it needs the engineering, logistics, and risk framework that turns a concept into a mission.

Here’s a full, structured summary of your uploaded document, written to preserve the intent, logic, and technical detail of your proposed 17‑person Mars Expedition. I’ve grounded each section in the document’s own language, including brief quotations where appropriate.

Mission Concept Overview
Your plan proposes a 17‑astronaut first Starship mission to Mars, built around a Triad organizational structure—groups of three specialists who share overlapping skills and can cross‑check each other’s work. This structure is meant to ensure redundancy, safety, and efficient task distribution in a hazardous environment. As you note, “It’s not possible to find a single individual who has all the necessary skills… There also needs to be inspection of work done by at least a second individual.”

The crew size of 17 is chosen for:

Social cohesion (similar to a large household gathering)

Avoiding overwork

Ensuring enough hands for construction, science, and exploration

Maintaining R&R time during an 18‑month surface stay

Crew Structure and Roles
Leadership (2)
Commander and Assistant Commander

Responsibilities: communications, data management, conflict resolution, task assignments

Provide final authority when disagreements arise

Geology Triad (3)
Hydrologist, Stratigrapher, Mineralogist

Tasks: site selection, seismic studies, water identification, mineral resource assessment

Critical for locating easily extractable water, not just ice

Construction & Maintenance Triads (6 total across two triads)
Heavy equipment operators

Electricians/electronics technicians

Habitat construction specialists

Tasks: unloading cargo, deploying nuclear reactor, building pit‑house habitats, installing airlocks, maintaining rovers, setting up solar arrays

Science Triad (3)
Chemist / chemical engineer

Microscopist / biochemist

Chemical technician

Tasks: sample analysis, life‑detection assays, running Sabatier and electrolysis systems, cataloging samples

Laboratory instruments include FTIR, polarimeter, HPLC, microscopes, ovens, and wet‑chemistry tools

Medical Triad (3)
Surgeon

General practitioner / dentist

Nurse practitioner

Tasks: emergency care, monitoring crew health, assisting with greenhouse/biological projects

Mission Priorities
You list five explicit priorities:

Stay alive and healthy

Complete primary tasks

Establish a permanent outpost

Conduct exploration with water as top priority

Return home safely

You emphasize that the first crew is a “skeleton crew” whose main job is to build a survivable, radiation‑protected base for future missions.

Logistics, Supplies, and Pre‑Positioning
Food
Your calculation uses:

Food = 0.02 ⋅ 170 ⋅ 17 ⋅ (200 + 200 + 1150)
Result: 41 metric tons of food for ~1550 days, including a 100% emergency margin.
You note: “Food required = … 41 tons.”

Water
~30 metric tons brought initially

Heavy reliance on recycling

Expectation of finding local water for long‑term use

Oxygen
Produced via MOXIE‑type systems or water electrolysis

CO₂ scrubbing and O₂ regeneration required for transit and surface stay

Cargo Starships
2–4 supply vessels pre‑landed or accompanying the crew

Additional 2–3 cargo ships if a second crewed Starship arrives in the same window

Many cargo ships are one‑way and can be disassembled for materials

Pre‑positioned equipment
Sabatier reactor

MOXIE or electrolysis plant

Cryogenic storage tanks

Nuclear reactor (possibly in a Dragon‑sized lander)

Habitat Architecture
Initial Phase
Crew lives inside Starship and inflatable habs

Inflatable habs lack radiation protection, so they are temporary

Permanent Structures
You propose composite Quonset‑style half‑cylinders:

Made from HDPE reinforced with carbon fiber

Installed inside excavated trenches (“pit houses”)

Covered with ≥1 meter of regolith for radiation shielding

Connected by tunnels to avoid EVA for routine movement

Modules include:

Living quarters

Vehicle maintenance shop

Science lab

Food storage and sample storage

Greenhouse (preferably built into a hillside for thermal stability)

Sanitation module

Dining / recreation / exercise module

You write: “These structures could be connected by tunnels… This would visually create a series of mounds.”

Power Systems
Primary: a large nuclear reactor landed separately and buried/bermed for shielding

Secondary: solar arrays placed on regolith‑covered habitat mounds

Starship carries a small reactor for life‑support redundancy

Vehicles and Heavy Equipment
You specify:

1 large rover (6–8 passengers; ambulance‑capable)

2 small rovers (3‑person, pickup‑style)

2 small tracked Bobcat loaders

2 larger tracked Bobcat loaders with backhoe

Trailers for ice transport

You note that tracked vehicles are preferred for Mars because “track vehicles work better on loose ground and inclines.”

Daily Operations and Workload
Standard 6‑hour primary workday

Additional 3–4 hours assisting construction or geology

6‑sol work week to avoid burnout

Everyone participates in construction during early months

Scientists and medics initially underutilized but become essential once base stabilizes

Scientific Goals
Your overriding scientific objective is searching for life, past or present.
You emphasize: “For me—finding evidence of life… is my overriding interest in ‘going there.’”

NASA participation requires strong science justification, making the science triad and laboratory essential.

Overall Assessment
Your plan is a comprehensive first‑mission architecture that blends:

Human factors (crew size, burnout prevention)

Engineering realism (heavy equipment, reactors, Sabatier, MOXIE)

Scientific rigor (life‑detection lab, geology triad)

Redundancy and safety (triads, nuclear + solar, multiple cargo ships)

Long‑term settlement logic (pit houses, regolith shielding, modular expansion)

It is explicitly a belt‑and‑braces approach designed to survive worst‑case scenarios, including missing a return window.

The Pentagon and the Energy Department for the first time airlifted a small nuclear reactor from California to Utah, demonstrating what they say is the U.S. potential to quickly deploy nuclear power for military and civilian use.

The nearly 700-mile flight last weekend — which transported a 5-megawatt microreactor without nuclear fuel — highlights the Trump administration’s drive to promote nuclear energy to help meet skyrocketing demand for power from artificial intelligence and data centers, as well as for use by the military.

Microreactors would be for civilian and military use

Currently, there are 94 operable nuclear reactors in the U.S. that generate about 19% of the country’s electricity, according to the U.S. Energy Information Administration. That's down from 104 reactors in 2013 and includes two new commercial reactors in Georgia that were the nation's first large reactors built from scratch in a generation.

The reactor transported to Utah will be able to generate up to 5 megawatts of electricity, enough to power 5,000 homes, said Isaiah Taylor, CEO of Valar Atomics, the California startup that produced the reactor. The company hopes to start selling power on a test basis next year and become fully commercial in 2028.
