GSLV-III puts Elon Musk on notice

GSLV-III Launch

GSAT-29 launches on a GSLV-III , 14 November 2018 (ISRO / 24FD.com)

ISRO’s largest rocket has made it to orbit again! The second operational flight of the GSLV-III took off from Sriharikota just after 0915 UTC with a new commsat that will operate at 55° East in the Clarke Belt.

GSAT-29 will serve the Indian subcontinent with four fixed Ka/Ku spot beams, two of which will focus on India’s relatively remote northeast and northwest regions. GSAT-29 also has laser and high-band microwave test payloads, plus a steerable Ka spot beam for focus coverage wherever needed.

Though competition is tough in the medium-lift GTO market, GSLV-III can now be considered flight proven. The new expendable launcher is already price competitive with the reusable Falcon 9, and is well ahead of Soyuz-2. The GSLV-III will also power ISRO’s manned space program, slated for liftoff in 2022.

A bumper crop of science for the ISS!

A great month for space science will be capped off 15 November with the launch of a new batch of supplies to the International Space StationAn Antares rocket will launch from Mid-America Regional Spaceport LP-0A at 0949 GMT, early in the Virginia Tidewater morning.

The 3000 kg cargo includes 12 science experiments, such as a 3D printer that recycles its own plastic, and breakthrough Parkinson’s Disease research – the Michael J. Fox Foundation’s CASIS payload is an improved version of an experiment flown aboard the ISS last year. If space-grown protein crystals can be grown large enough, and in sufficient quality to be imaged at 0.6 nm resolution – that may enough to find attack sites for drugs that could slow or stop the disease.

There are also studies about making concrete in space, making nanostructures to filter out carbon dioxide from industrial sources, and an ambitious German experiment that probes the very formation of the solar system using not much more than dust, electricity, and a 100 x 150 mm box!  Rounding this out is a Canadian VR experiment that tests how astronauts’ brains influence the sense of orientation, even without any gravity acting on the inner ear.

Payload Purpose
Refabricator Plastic manufacture / recycle
VECTION VR / flight effect on the vestibular system
EXCISS Solar system accretion / condroids
MVP-Cell 05 Concrete manufacture
CASIS PCG-16 Parkinson’s Disease / crystallography
CEMSICA Carbon dioxide filter nanostructures

Aiming for 43 AU

For this Leif Erikson Day, another reminder that the frontiers of exploration are still being pushed outward!

If you aren’t caught up, the Planetary Society keeps very good track of active missions and key upcoming dates. Wikipedia also has pages for almost all active space probes.

One of the most exciting recent developments have been the number of space probes from China and India. Compared to NASA and European missions, they have tended to be smaller in scale but more frequent, though perhaps th epace is not as frenetic as a Second Space Race as some had forseen.

ISRO even has a Mars mission – though oddly, the Mangalyaan Mars mission doesn’t seem to have the Electra radio relay found on most other Mars orbiters – the key part that lets the various Mars landers talk with Earth more easily.

At any rate, it’s a good time to pay attention! JAXA’s Hayabusa2 landed 3 landers on 162173 Ryugu just over the past few weeks. Plus, a look ahead at the calendar shows the planetary science crowd that the rest of 2018 is going to be more exciting than a fair bit of next year:

The BepiColombo mission to Mercury is set to launch this month!

The death watch for the Opportunity Mars rover will end soon. The rover was caught in a sandstorm in June and hasn’t been heard from since. While it’s possible that NASA will hear back from it, it seems more likely that its power systems have totally failed.

The Parker Solar Probe will reach its first close approach to the Sun on 6 November!

InSight will land on Elysium Planitia on 26 November 2018, supported by two 6U MarCO communications relays, in another first for CubeSats!

In December, OSIRIS-REx will reach its target, asteroid 101955 Bennu. Also two Moon missions, SpaceIL and Chang’e 4, are scheduled to launch by the end of the year.

Then, at just about the crack of New Year’s Day 2019, NASA’s New Horizons (of Pluto fame) will fly by 486958 Ultima Thule, the farthest celestial body ever to be visited so far!

The Martian Seasonal Calendar

A Flag For Mars

With the colonization of Mars so recently making headlines, I’ve decided to spend my Leif Erikson Day making my own small contribution to exploration.

I had talked before about a human approach to timekeeping on the Red Planet, but my concepts for calendar keeping have been through a couple iterations over the years.

What makes my approach different is that it focuses on the thing that makes the Earth calendar most relevant – the seasons.

The Martian Seasonal Calendar

  • Epoch: The calendar begins Year 1 shortly after the austral winter solstice of 27 October 1955. Roughly similar to Mars Year 1 in Planetary Science, shifted by one season.
  • Day of Week Collision: The Mars 2 probe crash of Saturday, 21 Nov 1971 / MSD 38404.  Future MSD % 0 = Saturday.
  • Autumnal equinox year of 668.5940 days
  • Month length about 30 days. Seasons are divided into a whole number of months.

Nomenclature

  • The days of the week are not renamed just for Mars.
  • Whether “day” or “sol” is preferred for someone living on Mars is left to future consideration.
  • The names of the months should be representative of cultural perspectives on the planet Mars from various cultures.  I can make suggestions, but really, an IAU process should develop a final list.

Structure

  • Austral Winter months – 178 days
    • 6 Months of 31, 29, 29, 29, 29, 31 days
  • Austral Spring months – 142(143) days
    • 5 Months of 29, 28, 28(29), 28, 29 days
  • Austral Summer months – 154 days
    • 5 Months of 32, 30, 30, 30, 32 days
  • Austral Autumn months – 194 days
    • 6 Months of 33, 32, 32, 32, 32, 33 days

Seasons have months of equal length “bookended” by slightly longer months.

Solstices and Equinoxes precede the start of a month by 2-3 days.  Radiative Forcing will keep the start of the 12th month about the maximum temperature for the Southern Hemisphere.

Leap Days occur in the 9th Month, halfway between the autumnal equinox and southern solstice, relatively close to perihelion.  Even if another point in the year is chosen for the basis of the tropical year, this is probably the best spot to place the leap day.

Intercalation

Odd-numbered years have 669 days and Even-numbered years 668. Years ending in 0 shall also have a leap day, but 6 decadal years of each millennium (170, 330, 500, 670, 830, and 1000) are not leap years.  Average year: 668.594 days.

Some background thoughts

The Autumnal equinox year is a 180 from the Vernal equinox year.  On the surface, it upends millennia of timekeeping convention, but it’s worth noting that Earth culture has been dominated by Northern Hemisphere sensibilities due in part to the much greater landmass above the equator.

When Mars still had its oceans, they occupied the Northern Hemisphere. The Autumnal equinox is also closer to perihelion, and the peak of the Martian dust storm season, the major weather event of the year.

 

Things every Medical Device Startup needs to know

atdc-theclubhouseMy visit to TheClubhou.se (more on the space soon) coincided with an ATDC talk on how to get a medical devices startup going. There’s an ongoing gold rush in the industry that has been tempered by harsh realities, and the overall effect of the Affordable Care Act, if anything, is a rush toward cheaper, then better.

It’s not easy for startups these days. The FDA, which used to look over clinical data and rubberstamp new devices for free, now has hefty filing fees – a new device from a major company pays over a quarter-million dollars just for initial approval, a process that takes up to three years. The small business “discount” lowers this to $65k.

Good luck raising money for a new idea. Probably the best way is with economic development or research grants, which are available from the public and private sector if you can keep your ear to the ground. If you can’t get a grant, try selling the concept directly to doctors, who will provide a ready market for your device. VCs and Angel Investors will take a cut of the company, without giving much in return. Loans are worse, if you feel bad about going bankrupt (which you will, because faceless banks aren’t going to make a startup loan).

Of course, there’s the nothing-new option: If you can make a convincing case that what you make is just a modern version of something that was in the market in 1976, of all years, then your product can receive an approval at the lightning speed of 6 months from now! Just pay $1600 a year for your federal registration.

Generally, to get FDA approval, you need clinical data. But to get clinical data, your device needs to see broad enough use somewhere. If you have something brand new, you aren’t going to be able to afford a private research study for your device in a broad context. So where are device manufacturers getting their launch data from? Europe, of all places. CE Rating is an easier, faster process, and Europe has a well-developed distribution network for medical devices. After a few years of sales abroad, you’ll get the track record you need to press forward in the States.

And then you’re really on your own! Once you’ve got your Rolodex out and accepted the fact that you’re a glorified telemarker now, you’ve got to convince hospitals and private practices to buy your device. And here, you’ve got three or four separate battles. Are insurers going to pay for your treatment? If you can convince them to file it under an existing treatment code, rather than make a new one, you’ll be fine.

There’s the issue of having separate markets in each state, often with unique licence requirements, and differing accounting standards. Among the worst for sales? New York and New Jersey, whose hospitals notoriously pay bills 6 months after the fact, when they actually pay them. Better states: Michigan, Florida, California. The device market tracks heavily with the number of older people in a state, go figure.

Can you get your thingamabob into a standard kit for the treatment you’re enhancing? This is where you really start thinking about selling out – every needle and scalpel in those things might very well be from a vertically integrated conglomerate.

Say you’re a tech entrepreneur aiming to make a million dollars. The exact words the lecturer used was “plan your exit” – the idea that, as soon as someone else has a major equity interest in your company, you basically aren’t going to run it forever anyway, so you may as well sell out, move on to the next idea. How to get there? Well, pharmaceutical patents are a headline item, those are still worth something. A device patent? Big companies have been known to buy others just for patents, kind of an external R&D thing, but they’re way more likely to buy out one with a working business model.

As someone who has mainly viewed the device industry as an endless march of ever-pricier doodads threatening to crush the national budget with nonogenarian cyborgs, it’s heartening to hear that the Affordable Care Act is finally getting more patients to feel the sticker shock. Instead of just going for “the best,” as doctors always recommended when money was no object – people are starting to settle for “good enough.” The real growth in the industry might just be finding ways to perform the same old treatments for less. It’s not the glitzy cutting edge engineers often want to live on, but inventing a cheaper wheel is not all dull retread work, either.

Gulf Coast Stuff

I got to see where they make planes and boats in Mobile, a couple fun things in Pensacola, and I managed to stop in Tallahassee to pay a little homage to Dr. Paul Dirac.

Gainesville was a great stop, too. Skillhouse is a great makerspace, they aren’t shy of giving first-time visitors computer help, for one. Tuesday night open houses can go super late, so it’s handy they have such a great break room!  Of what I saw, they’re more of a coding/electronics type of group, but to be fair, I only saw their “clean” space, in a downtown stripmall basement — the group also runs a woodworking shed across town.  The projects folks brought in ranged from an automatic plant waterer, to a bike rigged up to float a ping-pong ball in a tube.

Gainesville has an “innovation corridor” that runs from the University of Florida campus through downtown. One of these startups is a place called Fractureme, a service where they turn a piece of glass into a Kodakchrome piece of art. No need to frame – the back is foam-padded with cutouts, ready to hang on the wall! They come in padded mailers, and naturally they do replace the rare one the breaks.

Less blog more tweets!

My scheduling being what it is, it will be difficult to do full-length posts and make the most of the time remaining in the trip. So to throw up my hands, I’ll be basically doing a postcard/twitblog approach for the rest of the month, perhaps some short posts when appropriate.

Except for a lecture write-up I’m working on from Augusta, Georgia, which may come out in the middle of this photodump, everything should be able to stay in chronological order.  The next post in the vein of the trip is going to be about some things on the Gulf Coast but mainly SkillHouse in Gainesville, Florida.

Also, I will not be able to visit the Charlottesville Mini Maker Faire at the end of this month. Instead, I’ll be visiting some places in Ohio, Michigan, and potentially Kentucky and Pennsylvania.

The end of the trip is still going according to plan: Washington, DC in April, though the postings may stretch into May.  Also during that time, I’ll beef up the older posts as appropriate, and really start digging into the teensy minutiae like the best Hacker Heraldry.

Thanks again for your eyeballs! -j5

IDIYA in New Orléans, LA

idiyatablesIDIYA sits at Broad and Washington in the middle of the Broadmoor neighbourhood, in the heart of New Orléans. Sandwiched between Central and Mid-City, it’s dead-centre for the entire region – good, because the patience of NOLA commuters is not infinite. That was one factor behind the disappearance of the older space, GumboLabs.

The big glass storefront has the gallery on the one side, by the entrance, and the office desk far to the other wall. Between them, the black piping and lacquered wood of the central workbenches, clean, mostly clear, and ready for any of the 60 or so members to use!

idiyawoodshopWith the benefit of a generous landlord, the environs of IDIYA are prime expansion room, and already the backyard has been turned into a bit of a sculpture garden. In addition to the original shop space, they’re also setting up the building next door as a woodshop (which was freshly painted right before my visit), and then they’re putting up a metal shop behind that, in a quintessential Louisiana steel shed that looks to need some cleaning first.

idiyascannerIn the main building, there’s the obligatory general-purpose laser cutter and 3D printer bank (including a CubePro Trio that has never worked), but the most fascinating piece of equipment they have is a huge cartesian 3D scanner which can do a full-body scan in just 20 seconds, perfect for fashion designs!

idiyacentralThe central workshop is open, dominated by long, standing-height desks with gantries holding lights and equipment. Stage lighting bounces off the walls and ceilings, giving it a hip, studio feel. Scattered in the centre of the space are various projects, like the quadcopter hanging up on a post. There’s a CNC mill that’s totally encapsulated in an anti-dust tomb, freshly blackened from a session with a block of graphite. A 40-watt laser cutter sits at the heart of the main workshop, ready to chew up custom swatches of fabric. A pair of classic sewing machines and mannequins sit next to the vinyl cutter, rounding out the machinery for bespoke clothes.

idiyaschoolIDIYA is not shy of commerce, being a for-profit shop. It’s been a launchpad for entrepreneurs, and has itself managed to net a few design and modelling jobs away from the professionals at places like Entrescan. The other thing that sets IDIYA apart is that it’s a real school! A homeschool alliance meets at the space, with a sui generis STEAM curriculum. I can just hear the Phoebes now: “At my old school, we would make own own on the computer…” What an engaging, fun place to be able to learn!

Toward a Key West Dial Guide

Green: Reception. Blue: Reception with severe interference Purple: Negative reception but should have picked it up Grey: May be have been US station same channel Yellow or Black: negative pickup (black too weak)

the-blimp-is-out-there

I’ll have a Venti Propaganda.

I had the chance to visit the Florida Keys recently, and you can guess what I was up to – hitting the beach to avoid AM interference from local electronics, so I could listen to Cuban radio stations!

I did a dial scan for both AM and FM sides, each with its own issues.

The math for daytime AM is pretty straightforward, it’s all groundwave so you can model power divided by distance squared.  A rich vein of data is the FCC AM Query page.  I pulled every AM signal within 450km of Key West and start whittling down against my notes.  The main difficulty in going up against the FCC records is that…  the FCC records are notoriously bad for international listings.  They get Canada wrong on a regular basis (at least two times in recent memory, they completely dropped the ball watching out for Industry Canada assignments that impacted NPR signals in North Dakota), and Cuba is another story entirely.  I’m pretty sure Cuba gives about zero flips for frequency coordinating with the US when we’ve still got blimp blasters in the Keys.

Some other radio fans managed to snag some data off of EcuRed and turn it into a semi-manageable transmitter site list, which I can also crossreference after updating the list with some distance data.

Another handicap is that I don’t speak Spanish, so I couldn’t glean much about those programs (though advertising seems exclusively American).  The easy part is I don’t have to worry about skywave from Mexico or the Dominican Republic, or wherever.  Since I couldn’t wait around to confirm callsigns, I’ll be poking around trying to confirm certain US stations in my model had Spanish programming around 1pm on the 25th.  Once I have accounted for all the Florida-based Spanish-language stations, the remainder must be Cuban!

My radio rig is a 1994-era car stereo that’s in my Geo Metro, I’m not hauling any fancy Grundig or what have you.  One thing about this radio is that, especially on AM, it tends to bleed on either side of a strong signal, so when I was taking my notes I ignored a lot of nearby stations that sounded the same.  Yet, if what I’m reading now about the Cuban radio networks is right, there might have been more separate stations than I thought.

25feb-hepburnThe FM scan is more problematic.  Applying the same method as the AM scan, oddly, is not as sound of a model.  VHF signals are much more line-of-sight than AM, true, but at longer distances, especially over warm water, they are also subject to anomalous propagation through the atmosphere.  Tropospheric Propagation has a big fanbase in the ham radio community, it’s the main way uber-nerds snag a TV signal from 300 miles away.

According to the Tropo reports for noon on the 25th, there may have been a weak opening between the Keys and Cuba, and perhaps a hint more in the direction of Miami and the Bahamas.

Trying to sort out all the stations that might contribute to the FM dial readout will be tough, I’ll look at it more down the road.  Still, I’m pretty happy to have confirmed I caught at least two or three of the main Cuban radio networks.

Katy Makerspace

thekaty-18Starting west from downtown at 4pm, Katy may as well be in New Mexico. It’s about as exurban as you can get, complete with that malfunctional artery, IH10, for which no combination of lanes, tolling and HOV seems to abate the 5pm infarction. Traffic is terrible all over Houston, but this is plainly the worst of it, with too much distance to cover and hardly any parallel surface streets. Rather than dash way into town all the time, the creative types around here need a place of their own. Hence, Katy Makerspace.

thekaty-11Today, they’re turning up their new plastic extruder, made in the Lyman/Mulier [link] fashion, with an old RAMPS board inside. The beads of natural PLA come out clear to slightly brownish from the nozzle, making cobra-like swirls on the desk. A little leaks out the sides, smelling vaguely sweet as it caramelizes on the exposed brass. They’ve fixed all but two main problems: The diameter sensor wigs out in the harsh sunlight streaming in through the open garage door; Okay, run it in the shade instead. The thermistor is also under-reading, which makes the heater coil melt the plastic well above the semi-solid temperature where it could be pulled sideways and wound onto the spool. Just setting the temperature lower doesn’t work because of the stock RAMPS software, which kills the extruder motor below a certain temperature (in a 3D printer, the motor can burn out trying to push jammed plastic). So the next step is to drill another hole in the project case so they can plug in the USB port and change that setting or the thermistor settings.

thekaty-13One member, a gemological expert, who fills me in a little on how the ancients cut sharp facets in gems using little more than spinning discs and sticks, plans to use another similar extruder to spin over a tonne of glittering clear plastic beads, half PLA, half ABS, into print-quality spools costing about half what you’d pay at MicroCenter, perhaps with an additional discount for the non-profit spaces. The work stretches late into the evening; takeout is Domino’s, and the preferred beverage is beer – did you know Shiner Bock comes from Texas?

thekaty-8KatyMS has about 30 members, the most active of which are in just about each weekend. Those usual suspects include one one of the folks responsible for making the BuildYourCNC kits, which are beautifully custom-milled out of sturdy, water-resistant sheets of MDO – one such unit sits in the back of this shop! Another member runs back and forth trying to fix up the power supply on the FlashForge 3D Printer, swapping it out with a nearly identical unit from home for the time being. The leader of the space is a computer jockey, who brought in spare equipment like the rackmount and copier. Datawise this place is rigged out better than any place I’ve seen since Dallas, each wall lined with computer workstations; Internet by cable modem at the moment. A custom website checks members in and out.

They’re really keen on getting more of the region’s makerspace leaders together for some sort of council or convention, and like 10BitWorks, interested in doing a tour among nearby spaces. Katy Makerspace is definitely an active, industrious shop, punching well above its size. Well worth the trip!
