YHABFT: MIT MarsOne Analysis — Alternative Solutions to the Excess O2 Problem
A few months ago, a group at MIT did an analysis of the MarsOne mission that was fairly critical of the concept, on technical grounds. This week’s FISO telecon featured an update on the analysis they performed, particularly on the … Continue reading

Random Thought: Dragon V2 as an xGRF Platform?
Review: How Much Gravity Do We Need, and Why Do We Care? One of my hobby horses that I’ve blogged about a few times is the question of how much gravity do humans need to be healthy? As I’ve pointed … Continue reading
The Slings and Arrows of Outrageous Lunar Transportation Schemes: Part 1–Gear Ratios
[Note: I haven’t quite finished with my Venus ISRU series, but some of the articles I’ve read over the past few days drew me back to this series on propellantless lunar launch approaches that I started writing four years ago … Continue reading
Venus ISRU: ISRU Development Phases
In the last post in this series, we discussed methods for gas phase processing once the easily condenseable atmospheric constituents had been condensed-out. Before continuing on to a discussion about various processes for creating chemical precursors, I thought it would … Continue reading

Venus ISRU: Gas Phase Processes
In the last post, we talked about methods to condense out the five most readily condenseable constituents of the Venusian atmosphere (sulfuric acid, water, sulfur dioxide, hydrogen chloride, and hydrogen fluoride). In some ways the next steps of the gas … Continue reading

Venus ISRU: Condenseables [Updated]
[Note: Karl caught an important oversight in the comments. With a concentration of 150ppm and a boiling point of only -10C, Sulfur Dioxide (SO2) should also be considered a condenseable. It’s dew point is likely pretty close to water’s. So … Continue reading

Venus ISRU: What Do We Have to Work With?
In the last mini blog-post, we talked about some of the benefits of atmospheric-feedstock ISRU. But that leads to the question, what materials are there in the Venusian atmosphere, particularly in and around the 50km zone? While chemical engineering may … Continue reading

Venus ISRU: Benefits of Atmospheric Feedstocks
The concept of in-situ resource utilization (ISRU) has long been an important one for space settlement. The more one can “live-off-the-land”, the less one has to bring with them, the more affordable settlement becomes. If one can lower the cost … Continue reading

Venus ISRU: Introduction
While the Moon still has my “heart” when it comes to offworld destinations, I’ve long been interested in the idea of Venus Cloud Colonies (some references here and here and this article from earlier today). As several others have pointed … Continue reading

Random Thoughts: Columbus Article Link and Lunar Patents?
I don’t think this counts as my monthly blog post, mostly because I’m linking to and commenting on someone else’s blog post, but here goes. Michael Mealling (a fellow Masten Alumni gone entrepreneur) set out this year to do a … Continue reading
