I’m working on a big CAD project at the office, and I tend to zone out to music or documentaries. Below is another of the latter that I’m really enjoying at the moment.
This is a really great bunch of film history of the original astronauts from Mercury through Apollo. The restoration of these candid shots is wonderful, and for those of us who like to see space nostalgia walking and talking, it’s quite a sight. And yes, the background audio is not linked to the video, it’s a media presentation of what I understand was the third group of astronaut selectees. Enjoy!
One of the dual-purpose areas of interest for us is the blending of space development with terrestrial benefits. Not ancillary spinoffs, but really conscious efforts to make space technology directly applicable to earthly needs and desires.
NASA has offered a prize challenge here
for coming up with ways to use Martian materials for either textile production or for building structures. Outbound is particularly interested in building efficient and technologically advanced living and working buildings, so this is a pretty good fit. I think we’ll take a closer look at this challenge and work to submit a proposal.
Sigh. I had started this year strong, with every intention of averaging a post a day (or better) here. Obviously, I’ve gone off the path for that.
I have an out though: I said average.
This means that I have to post a lot more to get my average up, so I have my work cut out for me. And I certainly don’t want to just post junk, either. Then again, there is so much going on that good topics litter the ground these days.
To kick off my sprint to catch up with my plan, here’s the article that kicked me in the rear to get cranking again:
Well. That’s some big news.
Mars has liquid water.
It’s been long suspected, watching the changing striations over the years, and sensing what seems to be material of the proper density just under much of the service. But real chemstry showing the action of liquid water… that is truly the operational door that any future crewed Martian missions would need to walk through to do just about anything of real value.
You need plastic, water has the hydrogen.
You need working fluid for machining operations. Water works pretty well as a base.
Fuel’s the thing? Hydrogen and Oxygen split pretty simply.
Food? Water feeds plants and animals both. Mars already has carbon for proteins and carbohydrates.
Something to drink? Water, right?
You’re fond of breathing? Oxygen again.
This announcement today has been on the tip of our scientific tongues for decades, and now it can be spoken of confidently. It will take a bit for this to filter through current events, and for it to sink in with mission planners and policy makers. But it will.
Robert Zubrin’s The Case For Mars (TCM) has been in publication for a couple of decades now, and is a seminal work in the space advocacy genre. Really, it shares space next to weighty volumes like those from Carl Sagan and Gerard K. O’Neill.
It has occurred to me more than once that it would be useful to design an academic course around such books, with TCM as the main reference in this case. So, that’s what I’m going to embark on now. I’ve just picked up the newest edition and will give it as solid an evaluation as I can and start generating course materials.
I am not the only person in the space commentary community to have missed this flight test, but kudos to Blue Origin. They got half of what they wanted (capsule recovery yes, fly-back booster lost) and that’s very encouraging. Getting those fly-back boosters to work is proving more difficult than expected, I think, but now there is a second company joining SpaceX in developing the technique.
Based on information here:
And more in-depth technical discussion here:
It seems that work at Johnson Space Center (JSC) on an EmDrive, where microwaves are used to create thrust, may be generating warp bubbles. There is more work to be done to confirm the consistency of the results in a vacuum, but if it is real, wow. Just wow. Even small warp fields would be astounding to find so early in the field of warp science, and would absolutely belie the assumptions on energy densities required to create a spacewarp drive.
I am a very long-time supporter and member of the Moon Society, from way back in the 1990’s, and feel pretty strongly about the need to establish a beachhead on the Moon. There are a number of reasons for this.
From an orbital consideration, it is an extremely well-known commodity. Many nations have now landed something on the moon, orbited it, or used it as a means of sling-shotting to some other place in the Solar system. We know how to get there, and how to maneuver around it. There is something to be said for consistency. Geologically, it is nearly silent, and between industry and science, the nearly lab-like conditions and vast tableaus have a great deal of value.
It isn’t new.
I know, this doesn’t sound like a great selling point, but hear me out. With the Apollo missions, the Moon has been characterized enough in a few surface locations to build upon, if one takes a more cautious exploration strategy. For all of those detractors of the “flag-n-footprints” nature of the Apollo program, what better way to make lemonade than to actually derive a better and longer-lasting program of habitation based on what we’ve already learned?
It’s geopolitically valuable.
Humans will be humans, and sometimes they will fight. Maybe an economic war, or maybe a hot war, but nations are going to be at opposition of some level at all times in human history. Get used to it. As such, what value can be made of the Moon will initially belong to who lives there first. And I mean lives there, not explore or take a vacation there. Some nation, someday, will claim the place. Functionally, it provides a low-g jumping off point for other places. Militarily, it is the ultimate high ground in the Earth-Moon system. Woe is it to those who lose that race to a belligerent foe.
Of course, in the logic of zero-sum mathematics, there are a lot of people who think that in a finite field of funds, going to the Moon is stale and wasteful compared to Mars. If that is the logic in play, then Mars is also a bad place to go, because Asteroids have a very good chance of repaying the development costs and then eclipsing them in short order. Much shorter than Mars.
But really, the division between the two is a matter of apples-and-oranges, and does nothing but cause feuds between the proponents of the two destinations. As far as I am concerned, if the Triad is the road to the rest of the Solar system, colonizing the Moon is the maturing of the Terrestrial system. Certain circles are taking umbridge that NASA is doing quiet study on going back there, but personally, I think it’s great. I think it’s appropriate. However, Mars missions push us towards technology that we need to go anywhere else nearby, say the moons of Jupiter or Saturn, or even farther afield. Why throw such activity out in a fit of Lunachauvinism, either?
NASA is supposed to look to the future, and it is kind of unrealistic to think that planning for Moon missions would be ignored. Lunar activity doesn’t become any more or less impractical because political winds blow in another direction. Going to Mars is something else we need, too, so we can spread ourselves out and protect the species, and to foster freedom.
Leaving something permanent.
One of the saddest things about the Apollo missions is that they didn’t leave anything permanent that made future missions any easier. When Apollo was canceled, all that was left were museum pieces, pictures and a few hundred kilograms of rocks. But the nice thing about ARM is that once the asteroid sample has returned to lunar DRO, it’s there. It doesn’t require continued expenditures from NASA for it to stay there. Until we’ve mined every last bit of it, it’s going to be there orbiting the moon, close enough that almost any spacefaring country or business in the world can reach it if they want to. It doesn’t need an ongoing “standing army” that can be defunded. It doesn’t need a mission control to watch over it 24/7. It doesn’t need a sustaining engineering contract that’s going to suck up significant portions of NASA’s limited human spaceflight budget on an ongoing basis. It’s just there. Having something that accessible and permanent out there is worth something, at least to me.
This may be one of the best rationales in the whole ARM mission plan. If we want to have a permanent presence in space, we have to do permanent things. I am an absolute fan of the Apollo program, for a number of reasons, be it political, entertainment, inspiration, or technological and scientific. It was a great period in our nation’s history, and has importance beyond itself as a political tool. But Goff is right: it didn’t last. With significant funding, it could have been built to last, but it was primarily a political program, and when the holders of the purse strings had wrung what they wanted out of it, they moved on. All big programs face such a peril.
But ARM? It has the real potential to develop an infrastructure that can endure, and has practical reasons for why it should endure. We would be building a space exploitation milieu that is focused on resource development, as a product and a way to expand human activity to the solar system in an understandable way. If you want to create something that really lasts, you have to make it of practical value to as many people as possible. You have to show that practicality in a clear, unspun way. We can do that with a strong ARM.
