Just as God and Robert Heinlein Intended

While the news is distracted by the government shutdown, one of The Brickmuppet's Crack Team of Science Babes brings us news from Southeastern Texas, where consequential things are happening. 






And they are happening QUICKLY.

7 days ago, there were reports that Space-X might do a flight of their "Starhopper" test rig for their upcoming Mars Rocket in a little as 70-120 days. This was much sooner than had been projected. 

However, the engineers have been working nonstop, through weekends and with astounding alacrity. Now the prototype is assembled (at least externally) and Musk is hinting at a much earlier test. 
 SpaceX CEO Elon Musk says that the company’s first Starship prototype – a low-fidelity hop test vehicle – has finished assembly in South Texas, paving the way towards a series of experimental vertical take-off or landing (VTOL) hop tests that could begin as early as February or March 2019.

This is a low altitude test vehicle intended to work out hovering, and landing techniques and refine some design concepts for the ultimate design. It may well be run to destruction to test the limits of the vehicle.

Even more astounding, the first of the actual orbital prototypes is expected to be ready to fly as early as June pending the results of the Starhopper tests.  

The Starship Interplanetary Spaceship will be a remarkable vehicle. It is expected to be able to insert itself into orbit without a booster (albeit with virtually no useful payload). Assisted by the Super Heavy booster it will be able to carry more payload than even the Saturn 5, and transport 50 to 100 people to the Moon, Mars or beyond, or, for a more down to Earth application, a much larger number anywhere on earth in under 37 minutes as an inter-continental ballistic passenger rocket

The frantic speed of the test program is somewhat odd. One would expect a more reserved and methodical approach. There are a couple of possibilities, but two stand out. Space-X is tight on cash and just laid off 10% of its employees. It needs a spectacular PR stunt to woo more investment money. Also, NASA's SLS rocket, which has been delayed numerous times, is now expected to fly in 2020. If Musk can get a Starship orbital flight before then, that might well kill the NASA rocket (which, being expendable, and having a lower payload is inferior in every way). This would grant Space-X a much bigger share of the US launch market. 

This would also have the benefit of killing off a program that has already wasted 14 billion dollars of the U.S. taxpayers money just since 2011.

Remember that NASA was given a mandate to go back to the moon in 2005. Note that it's 2019. Using something we like to call MATH, if we take 2019 and subtract 2005 from it we get 14 years, which is exactly twice as long as the 7 years it took from 1962-1969 to do the exact same thing but with the exception that the technology was 50 years more primitive and going to the moon had never been done before. Now, 14 years after being told to repeat something done with far more modest technology, NASA can point to the fact that China has landed a rover on the moon, but on the far side, which has never been done before. Also; NASA'll have that rocket of theirs running soon

If Musk can pull this off, and finance the large numbers of rockets needed for the Mars missions he has planned, then the 2020s will usher in a new era in the history of mankind, one that may well save us. 

However, this project is pushing engineering to the limit. Some crashes and explosions are to be expected in the engineering test rigs. Unfortunately, investors and the public generally don't have a grasp of sound engineering principles and learning curves will look like failures to many of today's risk adverse generation. It remains to be seen if Musk can 
keep this most worthy of projects financed and supported.

Fingers are crossed!

Just as God and Robert Heinlein Intended



Space X has redesigned their interplanetary rocket, the BFS. 



The 55 meter long rocket now has three rather than two fins, each sporting a landing leg, presumably this gives it a wider footprint and more stability when landing on Luna, Mars, Callisto or Mercury. Its aerodynamics have been revised to further facilitate aerobraking.

The ship is to start doing short test flights next year but its big trial run will be a circumlunar test flight about 5 years from now. In addition to a crew of engineers and technicians to evaluate the ships performance and some scientists to do observations during the voyage, Must has, with his typical fair, provided luxury accommodations for some paying passengers on this flight. 

Well, Monday, it was revealed that Yusaku Maezawa., a Japanese  billionaire, publishing magnate, fashion guru and art connoisseur has bought up bought ALL the tickets. He plans to distribute the 6 to 8 other seats amongst various artists in the hopes they will use the experience to further their art. 

Elon Musk is focused almost fanatically on the settlement and eventual terraforming of Mars, though this rocket has far broader potential. Space X is touting the design for exploration and settlement as far afield as the outer solar system. However, the ship is non nuclear and relies on solar power for electricity, which is only really practical as far out as the Jovian system.


"He says with all the knowledge and expertise that a History major has in such matters."

That being said, The space between Jupiter and Mercury is really, really big. 

Furthermore, the engines run on Methane + Oxygen and the ship is designed with in-situ propellant manufacturing in mind. That is, given enough carbon, hydrogen and oxygen and sufficient solar power, it can make its own fuel. Mars, with its ice and CO2 atmosphere is ideal for this, but many asteroids, particularly the Trojans have considerable potential to be so utilized with some effort. This ship can potentially fuel itself and go anywhere within the limits of its solar collectors. Musk specifically proposes establishing propellant depots on Mars and Ceres to facilitate this. 

There's more from Musk here:


One of the concerns I keep hearing is that the Techweasels intend to use space as an escape route to abandon us and space will be the playground of the ultra rich

Roberta-X has thoughts on this.

I know it has become fashionable these days to decry space as a place where the rich will flee to escape us clods -- but in fact it is harsh and desolate, a set of environments where recycling isn't just a nice idea but a near-necessity -- and where conditions are such that you're already set up to work with harsh and dangerous processes while being isolated from them.  We can extract exotic metals and process radioactives on the Moon all we like and not endanger a single newt or squirrel -- or person, if they do it right -- and the aftermath won't be a spreading contaminated lake in China or a massive disposal problem in the Pacific Northwest.  

     Or, I suppose, we can hunker down in shared, egalitarian* poverty and every year there will be less and less, until one day, it'll all be gone.

Someone's gotta do the plumbing, someone's got to run the HVAC, and the aristocrats who aren't going to get their hands dirty aren't going to long be running things. What's going to be needed in space are going to be overwhelmingly what is seen today as blue collar, engineering, mining, construction/repair, mechanics, farming, doctors and short order cooks who can make the tilapia and zinnia taste different the thousandth time around.There will be very little need for lawyers, and NONE for sociology majors. I rather suspect that the need for an aristocracy whose jobs are based on status and appearances will not be strongly felt by the majority of those who will inhabit at least the early settlements. 

There was a similar issue in Jamestown in the early 1600s. The expedition was run by aristocrats who had skillsets that simply did not mesh well with the needs and morale of the larger organization. This situation did not last long. 

 
That aside, it is worth noting that Musk is particularly interested in making sure that his transportation system is affordable by ordinary people and not just the billionaires whose high end flights are financing it. It's mentioned in the above video when he discusses the Moonbase.

Yes. The Moon Base. 

This Kurzgesagt video got a response from Elon Musk within 24 hours.

 

You know, this here 21st century is finally starting to show real potential.

Copenhagen Suborbitals

Well this is neat. An amateur rocket club club in Denmark is looking to loft an amateur astronaut into space in the next two years. They're launching a proof of concept rocket from Jutland this summer and if their concepts are thus proven they expect to be sending one of themselves into space (but not orbit) in a year or so.

One Giant Leap

One of The Brickmuppet's Crack Team of Science Babes is all suited up and ready to go after observing the successful landing of the first stage of the Falcon 9 rocket. 



'Science Babe' is actually ZZGundam's Elle Vianno as rendered by by Monocoque.

The stage will be reused and that will go a long way towards reducing launch costs moving forward. This is a big step towards the fully reusable multistage rockets that have been dreamed of since Von Braun's time.


Space-X did a lot of similar operations earlier. Jeff Bezos's company which has a much lower performance rocket for suborbital space tourism achieved a similar feat a few weeks ago and several similar landings were done by the DC-X in the early 90s. However, this is the first time this has been successfully done as part of an actual satellite launch.

Abort Test

Space-X successfully tested its launch abort system recently. Instead of a disposable tower the system uses the landing retro rockets to remove the capsule from an exploding rocket and send it down range.

Handy Dandy Online Schedule

One of The Brickmuppet's Crack Team of Science Babes takes time from her twin hobbies of astrography and gunzelling to give us a handy dandy calculator for getting the most out of an interplanetary line-bash. 




The Cosmic Train Schedule has launch windows and trip times for Hohmann transfer orbits between Mercury, Venus, Earth, Mars and Jupiter (Sorry Ceres) out to about the year 2326. 

WHY one might have need for this? I'm sure that I have no idea. But it is certainly a neat resource and if one ever stumbles across enough unused Delta V laying about and decides not to listen to one's mom... 


...it will make a useful addition one's blaster and freezer gun.

45 Years Ago


How far have we come as a nation since that triumph 45 years ago?
Well, for one thing, here is big chunk from the sidebar of the YouTube page linked above. 


A dark age does not come about because a society simply can't do something they did before. That can happen because of a setback, changing conditions or hard times. Rather, a dark age is when the members of a society no longer believe that the society's great accomplishments could have possibly been achieved by mortals. 

Dark ages are bad things.

Well, THIS was unexpected



One of the Brickmuppet's Crack Team of Science Babes reacts to the astonishing news that wild Chimpanzees have mastered fire.

A few individual apes seem to have originally developed a rudimentary technique of rather poor efficiency, but the group gradually improved it through experimentation and observation over the last few months. They are now able to create and maintain a fire, which they have been using mostly to scare off predators and cook some of their food. Some individuals in particular among the group, seem to have rapidly grown a taste for cooked foodstuffs, especially flying squirrels.  

That's really COOL!
On the other hand....yeah.....we're doomed. 

UPDATE: Doomed I say. 
 
Even Updatier:
In the comments Edward M makes some claims that seem to revolve around the indefensible theory that nicking a story from Ace's sidebar before rushing off to work with none of the regular second source checking is somehow not a blogging best practice. 

As"evidence" for this unsupported and scientifically dubious notion, he calls into question the veracity of other news stories on the site linked above. 

Given the obvious presence of the word NEWS in the url this means that Edward M is arguing against authority...worse, given that out of a focus group of two blogs, the story has been treated credulously by 100% of the sample, HE'S ARGUING AGAINST CONSENSUS which as we all know is a form of denialism (not to be confused with Denaliism,...the worship of Mount McKinley...which this blog does not have an official position on) 

Furthermore, his calling into question the accuracy of other stories is easily debunked by demonstrating the non-impossibility of the news articles. For instance, it is known that Dracula was based on a real person (Vlad Tepes) so it is entirely possible that a descendant of that individual could be a mass murdering cannibal.  Assuming they existed, the Knights of the Round Table have to be buried somewhere, and England would be a logical choice, which would make finding the tomb of one of them in the UK unsurprising. I do not find it in any way unlikely that a single set of quadruplets containing babies of 4 different races would surprise experts. In fact, this story would be quite unbelievable if the experts were NOT astonished. If anyone were to claim that Putin is the third Antichrist...it would as likely as not be a Nostradamus expert. Libertarianism is far more likely to appeal to squirrels, than, say, bees. The story about the Sauropod terrorizing a group of oil field surveyors in Nigeria is in the Paleontology section, where dinosaur stories belong. The site has no cryptozoology section which is an actual indicator of high idiocy.

So there you go. 
I think my rebuttal speaks for itself.

F-1 in Huntsville!

My first F-1 post!

Two of the Brickmuppet's Crack Team of Science Babes report that Huntsville Alabama is home to the first F-1 test and quals since 1969 and the first F-1 ever since 1973!

Wait....

"Science Babes Moonlighting as Race Queens" is not the actual title of this piece by Tan-Tan.

If Formula One hasn't existed since 1973 what's this guy going on about?

"What?..."

"Oh!..."

The Science Babes are at their other job in Les Mans, which caused my confusion as they're actually talking about...

The Rocketdyne F-1 rocket engine!

The huge engines that powered the first stage of the Saturn 5 rocket which put 12 men on the moon and Skylab into orbit hasn't been built in 44 years. Contrary to popular belief the plans for these beast DO still exist, but they are in obsolete computer formats and of limited use.
You see, the Apollo program was so rushed that a lot of the little 'tweaks' that were found necessary to keep the rocket from failing. This was not fully appreciated until the '80s when NASA and USAF engineers noted that there were holes drilled and pieces added to some of the F-1s in museums...holes and fiddly bits that weren't on the plans. The engines were exploding during tests and the production crew did some trial and error modifications until the "splodies" stopped. Additional tweaks were added at the plant to facilitate production, so the F-1 plans are actually plans for an inefficient kerosene/LOX bomb.

Well, engineers in Huntsville have taken apart and are restoring some of these engines, which were discovered to be in remarkably good shape. This time making a note of Every.Single.Part. And. Hole. The plan is to do a computer model of the engine that is accurate, but they need to ensure that they are building it from a working engine...so.....



That's just a test of the engines gas generator from last year...
This project is the brainchild of Marshall Spaceflight center engineers who felt that they ought to DO something with the dozen or so F-1s lying around the research center. They've been calling in other rocketry companies to observe and consult. In addition they've been bringing in the few surviving Apollo engineers to work on this interesting side project...which has resulted in a tentative design and proposal for the F-1B 



 This is not as silly as it sounds. One of the things about the F-1 that was discovered back in the 60's was that, due to its very conservative design it was actually pretty re-useable and it was felt it could be made completely so with a few tweaks. F-1s were considered for several early space shuttle designs propelling reusable flyback boosters.



 The mighty F-1 may yet again spew pillars of fire for the chariots of explorers.

Mount Aetna Showing Off


The Youtube heading oversells it a bit. But it's still pretty neat.

UPDATE: In the comments Steven points out that the video is from 2000. Aetna (or Etna as seems to be the prefered spelling now) pulled this off last week too, leading to my confusion...I guess Etna  is just habitually awesome.

The Changing Pace of Progress

Progress...
In 1803 the population of the entire planet was a hair over a billion people. World economies were agrarian. Slavery of one form or another was practiced in all but a handful of nations.  Transportation was powered by muscle or wind, though there were a few clumsy steam engines doing the sorts of work waterwheels had done for ages in more congenial locations.



One hundred years later, there were telephones, telegraphs, steamships that could cross the Atlantic with thousands of people in 5 days.  Trains crisscrossed continents and industry had blossomed. Brazilians, Frenchmen and Germans had been flying experimental airships for a decade or more and on a cold December day at Kitty Hawk North Carolina,  a machine that was heavier than air took flight.



Less than 66 years after that (and 44 years ago today) humans set foot on another wold.



And in the 44 years since then?....well....the youtube page that is on is littered with videos claiming that it never really happened. As the 12 who walked on the moon pass beyond the veil the possibility increases that we will once again live in an age where no living person has walked upon the moon. The solar system, a vast storehouse of resources lies untouched save for a few probes, some debris and 6 flags planted there by a people who once could accomplish things.

Perhaps our children will redeem us...we have no right to expect they'll forgive us.

42 Years Ago Today


The crew of Soyuz 11 docked with the very first space station (Salyut 1) and stayed in orbit for 23 days, setting a space endurance record before they were forced to cut short their mission due to an electrical fire on the station.



During the re-entry of the Soyuz 11 capsule , there was a loss of radio contact, but the spacecraft landed quite normally in Kazakhstan.

Tragically, when the recovery team arrived however, they found that a pressure release valve had opened during reentry and exposed the crew to the vacuum of space. They were not wearing pressure suits. Despite the best efforts of the recovery team to revive them, Georgiy Timofeyevich Dobrovolsky, Viktor Ivanovich Patsayev and Vladislav Nikolayevich Volkov had died on re-entry.

As terrible as this was, it bears remembering that if the boundaries of the future are allowed to be set by the, the timid, or far worse, those who would presume to forbid others from striving for great things...then our future will be a dark age. The human race is fortunate to have people such as these who will step into the breach and attempt great deeds.

They deserve to be remembered.
