"Swedish for common sense."


At some point, we will begin to colonize the rest of our solar system.

Science fiction - and science fiction fans - just take that as a given.  How could we not?  And as such, science fiction is full of examples of Moon bases and Mars colonies and space stations and so on.


However, the finer details of the process are frequently left to the imagination.  I've been rewatching The Martian, the excellent 2015 adaptation of Andy Weir's equally excellent novel*, on Netflix™ and it occurred to me that they never really discuss where the Hab module on Mars comes from.  In the movie, it's apparently quite a solid structure, although in the novel, it's just a bubble, held in shape by air pressure (which makes the scene where the airlock blows out a bit more challenging for the abandoned astronaut Mark Watney, because the entire structure collapses).


But it takes more than air pressure to make a house a home, to misquote Walter Brennan.  It takes desks. It takes desks, and beds, tables and chairs, shelves and cabinets, and all the other bits and pieces that make up a functioning living and working space, whether it's on Mars or the Moon.

Ignoring the question of how the Ares 3 team put all this together in a couple of Martian weeks, how did all the bits and pieces get there?  We're looking at a situation where both space and weight are at a premium: every milligram matters when it comes to fuel consumption, as demonstrated by the process of demolishing the Ares 4 Mars Ascent Vehicle so that it has enough fuel to take Watney to a rendezvous with the Hermes.

So far, this sort of thing hasn't been a real problem for NASA.  The International Space Station is constructed from prefabricated modules that have been boosted into orbit and assembled** over a time span of almost 20 years, and it doesn't need furniture as such - lack of gravity makes wheeled office chairs a bit redundant.

However, as soon as we start setting up a base in any kind of a gravity well, furnishings will become an issue, and NASA will need to look at the logistics of transporting all the associated bits and pieces required to create a functioning and livable habitat to another world. It will require lightweight modular furniture, packaged so that there is no wasted space, and which can be assembled easily and quickly with a minimum of tools.

But where can they go for this sort of expertise?  Hmmm...oh, wait, I know...

* To be honest, I feel that the novel is a bit more excellent than the movie.  It's certainly more sciency.

** Shout out to both the Canadarm and the Canadarm II.

And the winners are...


It's the 150th anniversary of Confederation*, and although it's not officially part of the celebration, Prime Minister Trudeau chose Canada Day to announce the names of the two successful candidates in the recruiting process for Canada's next astronauts, chosen from 3,772 applicants over the course of a twelve-month selection process.

This process was designed to find the people with "the right skills and character to become Canada's next astronauts", to quote the Canadian Space Agency web site.


Candidates were subjected to an exhaustive array of tests:  medical, logic, intelligence, physical fitness, strategic thinking, critical reasoning, dexterity, resourcefulness, motivation, leadership and, in the final stages of the process, robotics, health and communications, followed by a final interview with a special committee of CSA executives, industry experts, and astronauts, both former and active.


And the winners are?  Joshua Kutryk and Jennifer "Jenni" Sidey, both originally from Alberta - Kutryk from Saskatchewan and Sidey from Calgary.

Sidey has worked as a combustion scientist and a mechanical engineer.  She has two degrees in engineering, including a Ph.D. from Cambridge. Kutryk, a Lieutenant Colonel in the Canadian Armed Forces, has been both a test pilot and a fighter pilot, and has degrees in mechanical engineering, space studies**, flight test engineering, and defense studies.


It's interesting to look at the stats from the start of the process.  It's not too surprising that the majority of the candidates were from Ontario and Quebec, but it's intriguing that Alberta had the third highest percentage of applications - British Columbia's population is 13% larger, but submitted almost 5% less applicants. Is there something about life on the prairies that makes people dream of space? Or something about life on the coast that makes them less eager for adventure?

The saddest statistic on this infographic is the total number of applications started versus the number completed.  I'd like to express my sympathy to the 4,021 people who started on the challenging path to space travel, but then discovered that it was a path that they could not follow. Dreamers, optimists, or just people who had one too many drinks - I feel for you during that moment that you decided that you weren't the right stuff.

My congratulations to Jennifer and Joshua for having the determination to follow their dream to success. Please remember that you're there for all of us - especially those 4,021 others.

* Why do we not call ourselves the Confederation of Canada?  It has a nice "United Federation of Planets" sound to it.

** You can get a degree in Space Studies?   Apparently - although according to their website, it appears to be a minor.  http://catalog.erau.edu/daytona-beach/minors/space-studies/

Counting down II.


With one week to go until Canada's 150th birthday, here's a video about the distinctive nature of our country from one of our great national icons: Dave Hadfield.

And his brother Chris.

(My favourite part of this video is at 3:11, where we watch Canada's best known astronaut solemnly launching a thirty-five dollar model rocket.)
