This post is part of the series on space topics. This post is not the last word on this topic. The usual caveats apply. I’m curious if you have strong opinions on different fuel mixes. A growing Mars base has a prodigious need for power. I’ve previously written two posts on powering the lunar base. The first explores solar power towers and thermal storage. The second reveals that beaming power to the lunar base region with microwaves from Earth is by far the cheapest, most flexible option – for operations on the Earth facing side of the Moon.  This, incidentally, …

Stuff you should have been taught in college but weren’t

As part of my job running Terraform Industries, I get to build an amazing team of super smart people, and that involves interviewing hundreds of people. Over time certain patterns have become obvious, but I remember when they weren’t obvious to me on the other side of the table! It has become clear to me that there are some subjects that should be covered as part of any professional degree and are not only not taught and not discussed, but most otherwise highly qualified graduates are completely unaware of their existence.  I have previously written about improving resumes, becoming a …

Moon Escape!

[One from the archives, a previously unpublished short story I wrote c. 2017 on the theme of BASE jumping.] Why anyone thought a prison on the Moon was a good idea was beyond me. Remote, dangerous, inhospitable, to be sure. But certainly not impossible to escape from, as I was about to show. I had been ‘quartered’ in Block D, formerly optical scientist research and habitation module. Half buried in lunar dirt, the squints had wanted light, so Block D had some narrow slit-like windows near the ceiling, unlike the other blocks. From this window I could watch the Earth …

Dittemore’s Law

A quick note to formalize some observations on elite organization dysfunction. The Space Mirror Memorial at Kennedy Space Center in Florida commemorates the 25 US astronauts who have died in flight.  Ron Dittemore is the retired former Space Shuttle program manager who was ultimately responsible for the series of decisions that resulted in the Columbia disaster, which killed seven of the lost 25 astronauts. Throughout my career I’ve become increasingly obsessed with a particular and fairly obscure form of institutional failure. I haven’t seen much written about its general form, so I’m writing this post to collate my thoughts.  Dittemore’s …

The Los Angeles wildfires are self-inflicted

I don’t ordinarily write about events “in the moment” but for this I will make an exception, as I was personally affected. Caveats aside, my family and I are safe, we evacuated for several days, and due to heroic efforts by professional firefighters and psychotically brave neighbors, my house and most of my neighborhood escaped destruction. We were the lucky ones – by far. In 2019, as my wife and I were house hunting, we inspected multiple homes in the Pasadena area. Every house we looked at in Altadena burned to the ground last week. I watched the Eaton fire …

Salton Sea statistics

I wanted to gain better insights into the Salton Sea level, evaporation, inflows and outflows. Step one was to gather publicly available data about its level, and collate it into a single graph. Here we see that despite the continual formation of Salton Sea advisory committees, the water level increased about 12′ after 1950, flooding many coastal resort towns, and then began a precipitous drop in about 2000. [Edit: If you enjoy this kind of thing, you may find a career at my company, Terraform Industries, rewarding. We’re hiring smart ambitious people in Los Angeles to bridge the gap between solar energy …

The call of the Whimbrel

The seven-note whistle of the Whimbrel is a classic sound, welcomed by Icelanders at the end of a long, dark winter. These wonderful waders are responding badly to recent changes to Iceland’s landscape, such as the ever-expanding areas of non-native forestry and power infrastructure. Conservation of the species may be supported by reserving areas for … Continue reading The call of the Whimbrel

NSF targeted with mass layoffs, acc to Politico; huge cuts in president’s budget request

According to this article at politico, there was an all-hands meeting at NSF today (at least for the engineering directorate) where they were told that there will be staff layoffs of 25-50% over the next two months. This is an absolute catastrophe if it is accurately reported and comes to pass.  NSF is already understaffed.  This goes far beyond anything involving DEI, and is essentially a declaration that the US is planning to abrogate the federal role in supporting science and engineering research.   Moreover, I strongly suspect that if this conversation is being had at NSF, it is likely being had at DOE and NIH. I don't even know how to react to this, beyond encouraging my fellow US citizens to call their representatives and senators and make it clear that this would be an unmitigated disaster. Update: looks like the presidential budget request will be for a 2/3 cut to the NSF.  Congress often goes against such recommendations, but this is certainly an indicator of what the executive branch seems to want.
