Nautilus-X - NASA's Multi-mission Space Exploration Vehicle Concept

Click For Summary

Discussion Overview

The discussion centers around the Nautilus-X, a NASA concept for a multi-mission space exploration vehicle. Participants explore various aspects of the vehicle's design and feasibility, including food supply, life support systems, and the implications of NASA's budget constraints on the project's future.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants express optimism about Nautilus-X potentially ushering in a new era of manned space exploration, while others are skeptical due to NASA's budget issues and past project delays.
  • Questions are raised regarding the logistics of supplying food for six astronauts over a 24-month mission, including the feasibility of carrying frozen food versus growing it with specialized lighting.
  • Concerns are mentioned about oxygen regeneration and CO2 elimination in the Nautilus atmosphere, with references to past issues faced by early Russian space stations regarding atmospheric composition.
  • There is uncertainty about the mass implications of growing food in space, as it would require additional nutrients, seeds, and equipment, potentially increasing the overall mass of supplies needed.

Areas of Agreement / Disagreement

Participants express a mix of interest and skepticism regarding the Nautilus-X project, with no consensus on its feasibility or future due to differing views on NASA's budget and planning reliability.

Contextual Notes

Limitations include unresolved questions about the specific technologies for food supply and life support systems, as well as the dependency on NASA's budgetary decisions and project timelines.

I'm very interested in Nautilus-X, looks like it could really usher a new era in manned space exploration. Unfortunately considering the track record of NASA's various plans for the future over recent years along with the budget issues I'm not holding my breath that this will become a reality. It would be great if it did but I can see it being suspended due to budget cuts and that 2030 goal for a Mars mission being pushed ever further into the future.
 
What is the concept in supplying food for 6 astronauts for 24 months? Carrying about 5 metric tons of frozen food, or growing food under special GRO-lamps? What about oxygen regeneration and CO2 elimination from the Nautilus atmosphere?
 
There's a summary of the project http://hobbyspace.com/nucleus/?itemid=26786 (bottom file, Holderman 1-26-11).

I'm not sure how they plan on getting the food, I presume it's frozen because if they grow it they would still have to take all the nutrients, seeds, equipment etc. It would end up massing more that way. How they plan on scrubbing the air will be interesting, IIRC one of the early Russian space stations reached dangerous levels of methane in the atmosphere from all the...natural processes of the astronauts.
