The Curious Mind of Ada Lovelace

J05H Re:Not the first programmer. (110 comments)

Almost all of that technical heritage in the logic of weaving was maintained by women across cultures. An example contemporary to the lovely Ms. Lovelace and Mr. Babbage would be the founding of the Rhode Island School of Design. That institution was funded by ship's captains to maintain their most talented daughters in programming Jacquard looms for the local textile industry and other arts. Today it is a eminent art and design school if not the best. If not the first programmer, Lovelace was the first non-inventor/nerd that programmed, ie. the first application programmer.

World Space Walk Simultaneously Puts Three Mars-Capable Spacesuits To the Test

J05H Upcoming Paper should be interesting (39 comments)

They are publishing results in Astrobiology to create a standard metric for analog space suits. Operating standardization is a great next step for this field.

On a human-factors standpoint it will be interesting to see the energetic differences between the suits. One issue is they are being tested in different place with different wearers.

Consumer Device Hacking Concerns Getting Lost In Translation

J05H The rug (100 comments)

Stop sweeping problems under it.

If these devices are vulnerable then they will be exploited. The best solution is transparency and working consortia for both testing/verification and patching these problems before that vehicle, pacemaker or other device is used against consumers.

Draft NASA Funding Bill Cancels Asteroid Mission For Return To the Moon

J05H Logic: (237 comments)

Asteroid retrieval is about $1-2 Billion spread over a decade. Single moon landing is at an order of magnitude higher at $10-20 Billion with unknown duration. This is what happened with Shuttle and Station and appears to be happening with SLS: they eventually sucked cash out of other NASA programs while legislators direct even more resources into those single projects as if 10,000 people working together can't manage more than one task.

We should go back to the Moon but that should not prevent us from also snagging an asteroid. The funny thing is that the returned asteroid was planned to go into Lunar or very eccentric high orbit, either would have been a great shake-down cruise for Orion before going to the Moon.

What Features Does iOS 7 Need?

J05H USB drive & printing (262 comments)

iOS 7 should let the device act as normal flash storage. This is a crippling weakness in Apple's current devices and traces all the way back to the Newton's custom filesystem in the 90s. Seamless printing, especially with all the wireless printers around, is a no-brainer.

Eric Schmidt: Regulate Civilian Drones Now

J05H Re: How would you feel about it? (420 comments)

If the drone is over someone else's property, it is trespassing in their airspace. This may be especially true below 500' and anything over that is FAA controlled. So the drone flying neighbor is either going to be violating your property or common airspace.

If the neighbors' houses were close together and the person was still over their property but actively observing your property? That would be interesting in court.

Romney-Ryan Release Space Policy Paper

J05H Re:What NASA needs. (378 comments)

Funny how the truth barely gets modded. Space manufacturing "will" be huge even much bigger than Earth's industrial base someday. Digital Fabrication is going to push this forward very quickly in general. Luna has specific issues in severe lack of volatiles. For now any precision machinery will still be built on Terra.

The idea of it being "cheaper" to launch deep space flights from the moon seems to come from a purely gravitational notion. Ignoring economics, politics and thermodynamics (not to mention that any clients are going to be in LEO) this idea is and always has been a has been.

Ask Slashdot: Is the Rise of Skeuomorphic User Interfaces a Problem?

J05H Skins (311 comments)

This is an argument for skinnable UIs, modifiable UIs and GUI/CLI cross use.

Every user has their preferences and we should be able to customize our computers to those preferences. If you want the faux-wood paneling, it's there. If you want some Strong Typing, you should be able to interact with it in bash. It'd be great to be able to type batch commands for Photoshop, even if it was just simple stuff like crop and re-save.

Space Tourist Trips To the Moon May Fly On Recycled Spaceships

J05H Legit Hardware (95 comments)

Amazing fact: in a world of vapor projects Excalibur-Almaz is one of the few new-space companies with flight proven hardware. The VA capsules and TKS modules are heritage Soviet equipment with upgrades. This is some of the finest spacecraft designed by one of the greats of the early space age.

Hopefully they actually get to (lunar) orbit with paying customers. Also, 15X reusability plus integration on Falcon has strong cost implications after first flight.

Ask Bas Lansdorp About Going to Mars, One Way

J05H Biology (540 comments)

How are you going to deal with potentially hazardous forward- and backward-contamination and the pressure to conform to bioethics principles in the face of "go fever"? Two planets are at stake.

We have barely scratched the surface of Mars and do not know if there is bacteria or larger life there. I ask everyone else that is working on humans-to-Mars this question. Almost everyone that is pro-space has a cowboy attitude about it but the facts are that the first footstep on Mars begins the terraforming process and if Mars has any life that anyone going there is never coming home. "We'll deal with it later" does not work in planetary protection and spoils a lot of the bio-science that can be done virtually on a living Mars.

The MarsOne project will have a lot of "go fever" or pressure to execute because of the funding model. Any human mission to Mars needs to take the time to do the biological research before committing a crew to the surface. Four people dying from something hostile on the surface of Mars makes for a great movie but terrible reality TV.

Also every Mars one-way mission proposed has faced immense negative public pressure because they always are labelled as a suicide mission.

FYI my argument boils down to needing extensive realtime ops from Mars orbit in support of surface development and a need for an orbital forward base. Producing this resource is my long-term plan.

Planetary Resources Confirms Plan To Mine Asteroids

J05H Water (500 comments)

Water is by far the driving material resource. Metals are insignificant compared to water for human utilization. That Planetary Resources wants to track NEOs is also important. They have definitely done their homework.

When this news started to break last week it was unclear if they were just going after PGMs or had a more comprehensive strategy.

Billionaires and Polymaths Expected To Unveil a Plan To Mine Asteroids

J05H Minerals are not the next step (531 comments)

Electricity is the next step. Power beamed to provide propulsion and operating energy to other spacecraft. After that, beamed power to new space facilities, then gigawatts of green power to Earth.

Then water. Jim Head says "Follow the water." Find water sources that are at or near the top of the gravity well - Phobos, Deimos, Amor-Atens or Earth-crossing NEOs with high water content.

Those two resources enable reliable access to the Lunar and Martian surfaces. Minerals, lunar polar ice and many other elements are further down the list of needed (re: profitable) materials.

That said, such a well-heeled team has surely looked deeper into the specifics.

  Booth media included graphics explaining the STREET space ring and the Postcard Display.

October 22,2006: Postcards To Space featured in Aero-News.net!

Wirefly X Prize Cup Wrap Up

I just got back from the incredible Wirefly XPrize Cup. This was by far the best space event I've ever attended. Conferences might be more informative but this event had the volume turned to 11. As I was flying a booth, I didn't see much actual flying, but almost everything was perfect and incredible. Since inception and the Space Ship One flights, the XPrize has been rocking the foundations of the space community. The star-spangled spaceplane has really made history.

Both the original prize and the new Cup are changing the way people think about Space. Even with this geometric change in attitudes, some things never change. This rant includes observations, lessons I learned, gossip that you won't find anywhere else and one major prediction.

For everyone reading this that attended the XPrize, please tell people about it. Tell them about what you saw and help spread the word. Only you can make "space" happen.

On Friday, nearly 10,000 school children arrived for the event. Their enthusiasm and bright smiles were infectious. My greatest hope for these space events is that they inspire this youngest generation to pursue the new frontier.

People I'd like to thank include Denise and Nancy who handled Logistics for this very complicated event. All the volunteers and people that put blood, sweat and tears into making it happen deserve applause. Thank you. Sky Fire Lab were the best booth-neighbors ever, it was great seeing Evan again and fun meeting Kevin and Jessica, Mike, Kayoko, Yuki, Phil, Rocky, Kennda, the whole VR Skydive crew and Monica, Aaron and Darla from Seattle. Thanks to everyone who stopped by the Postcards To Space booth and especiallly those who stepped up and voted with their dollars.

None of this would be possible without the investment and foresight of Dr. Peter Diamandis and the Ansari family. All of these folks share the Vision Thing.

Good stuff that happened in my presence includes seeing Jon Carmack and team resting in the shade of the broken Pixel, after the first day of flying, exhausted and happy as a kid. He's doing rocket science and immense fun. The Tripoli rockets were fascinating, a class of high-power amateur rockets built by students and young adults. Some of these rockets break the sound barrier seconds after launch, truly a crowd pleaser.

VR Skydive provided a vertical wind tunnel and crew of coaches to provide another crowd pleaser: flying in the blast of air from this portable training facility. Put on a parachute suit, goggles and helmet, get in and the coaches stabilize you as you are lifted by the airstream. They literally fly out of the top of the tunnel cage, it's amazing. Patrick, Abe, Matt, Amy and James kept everyone safe and having a great time. Free flying on a blast of prop-wash is one of the coolest things I've ever done, I'm actively coming up with excuses to become a tunnel rat.

OK, now for the Dirt and lessons I learned.

Let's start at the beginning. After Teddy and Bunny, the first toy I remember is my plastic Apollo lander. I've been a member of the Planetary Society for 2 decades and taking part in space conferences since CATS in '97 (thanks again, Chaz). Back in the 90s, I brainstormed on sci.space.policy with the brains behind many NewSpace companies including SpaceDev, XCOR, Rotary Rocket, Armadillo and others. Some have come, some gone, others enabled a private astronaut to fly in space. I built the first SpaceDev website in '97 and was at the first SS1 XPrize flight in September '04. My art has included space themes consistently since childhood, inspiring me to begin development on the world's first space sculpture, the STREET space ring. I can be found online in my role as the informed peanut gallery on uplink.space.com as J05H and as user #5625 (J05H) on Slashdot. I've been doing this space-advocacy thing for a long time.

This isn't bragging, my credentials need to be established for what you're about to read. I'm inured to most geek's antisocial behavior and have already had one assination threat over my project. Opinions don't scare me.

The XPrize Cup was one of the coolest events I've ever attended, be it conference, concert or party. Almost everybody there ROCKS. There are lessons that I learned from the people that don't rock and the interactions we all had.

Karma affects everyone, geek, astronaut and businessperson alike. My first encounter during Thursday's setup was seeing a guy named Bill wearing a t-shirt that reads "Rocket Scientist". My second encounter was over-hearing several graybeards express the most basic human reaction: blustering arrogance in the face of superiority. Quote one guy regarding his company's unflown hybrid motor versus a flown competitor's engine, "I try to kick his ass at every opportunity."

Another replied "He says he'll be first to flight."

The first answered back, "Goes to show you shouldn't believe your own hype."

Two days later, proving karma brings all full circle, this same dude tumbles off a chair at the SFF closing party. His competitor was both not drunk and not falling off chairs at the time. My wife says this shouldn't be public info and that this man should be told this to his face. I think it should be very public (if anonymous) and that braggarts and chair-divers do great harm to their efforts. Perhaps I will tell it to his face.

I understand there are big egos involved in NewSpace and potentially lots of money. Aerospace has always had plenty of bravado, arrogance, puffery and one-upmanship. There is a huge difference between one-upping a competitor and cutting him down.

As a martial artist, ego interferes with Doing. Flight and rocketry are similiar at this critical level: egos kill crews and dreams. Dan the Rocketman flies his peroxide-powered rocket belt without ego or undue emotion, a drop of anger or hubris spoils his day. He displays the calm and control of a Roshii, a Zen teacher. There is always someone smarter than you. Thinking you are important is vastly different from doing important works.

My Lesson One: There is usually someone watching.

Amid the blossoming enthusiasm of a sea of school children, I stepped into the trap of Team Toad. Instead of tapping the cameraman at my booth on the shoulder and asking "Hey man, what's up?", I walked right into my booth and caught their media assault full force. Next time I will know better.

It was early in the morning and I had returned to the booth with only my 3rd cup of coffee to find a flying wedge of 5 or 6 engineers and as many video operators. I hesitate to call the video crew a "documentary" team, as they lacked the critical girl-ninja (see below) or any sense of decorum. During this attack, the head of Team Toad stood in front of me long enough to hear the short version of my pitch then proceeded to pretty much say "Hey, your pretty cool. Do you want to, like, do business? Heh, heh." It was totally Beavis and very uncomfortable. At the end of this, their producer lady dropped a clip board with a release in front of me.

Professionals have a biz-dev who travels the show with perhaps an engineer to OK things. He's as likely to have an old NSS friend or college roommate along, not the largest film crew at the XPrize. NOVA has a smaller film crew including host, than Team Toad. Plenty of companies stopped by the booth, chit-chatted and exchanged cards. They all rock. None of them stuck 18" boom mics that looked like stuffed animals in my face. Team Toad here is a clue from a media professional: learn how to use that camera. If you're going to tote around a crew that size, SCHEDULE YOUR INTERVIEWS!! Not "Can I bring a couple of my guys around?" as you asked, but "I'd like to interview you in a sit-down location, what would be a good time for you?" I'm not sure if Team Toad has any flying hardware, but I hope they are better at rocket science than representing themselves in the New Media.

My Lesson Two: Know your tools and environment.

In Shogunate Japan, the kunoichi were specialized girl-ninjas that did the things their male teammates could not. No longer wielding kunai, naginata and themselves as weapons, these young warrior-women still tread among us. In the 21st Century the modern girl-ninja holds a hallowed position as moderator, troubleshooter and reaper of the tech whirlwind. She is Athena reborn. Every media team, crew and studio that functions properly has at least one of these young women. She is often assistant, PA, producer or video editor. No media organization can work effectively without the girl-ninja keeping everything Rolling. This is exhibited in the following two examples.

A little bit more about VR Skydive and their portable wind tunnel. This incredible machine blasts a stream of air upward, essentially allowing you to fly. They use it to train for skydiving and thrilling people. It is an incredible crowd-pleaser and great place to scout VIPs. I was watching the action, earplugs in, toward sunset Friday, hoping to get in the next group. A beautiful young woman approaches, taps me on the shoulder and asks who is in charge. She thanked me and proceeded to do the nerd equivalent of cutting in line. This involved her crew and instantly recognizable television science host approaching while we chatted about a mutual colleague. This young woman is their team's ninja, she is polite, smart, sociable, gets stuff done and leaves everyone satisfied with the result. Hanging with these folks was informative and fun, and didn't involve boom-mics that look like hunting trophies.

As this team of gifted people finished up on the wind tunnel, another girl-ninja strode past, walked right to the wind tunnel boss without asking anyone anything. She is a higher level ninja, she always understands Who is Who. Moments later her crew descended on the drop zone so that one Mr. Ansari and party could fly the Friday sunset. Elfen and soft spoken in the silence between wind tunnel runs, she epitomized the motif of getting things done while running point for 15 people and her boss. I exitted for their privacy. Compare those professionals to Team Toad's twiddling.

My Lesson Three: Decorum counts.

There is a value in the space between play, patience and truth. Getting bumped off the wind tunnel Friday proved incredibly interesting, patience allowed me to fly it twice the next day. Truth got my cousin and a friend onboard as well, for the perfection of flying in Saturday's sunset. Play is the greatest motivator after hunger. People stood around the wind tunnel for hours for one minute of lift-off.

A guy named Rocky is forming a freefall football league. It's the coolest thing I've heard about in a long time. Play can be both stress reliever and creative act: I want to field a team for his league. Truth unites play and patience; the three together create a dynamic environment that can change the world.

Now for some raw gossip. During Thursday's setup time, the VIPs held a very hush luncheon. It is, after all, what VIPs do. Having heard a rumor after breakfast, I was surprised when a business jet landed around 11am. During the landing, a local piped up, "That's Al Gore's plane. I saw it on the manifest."

No word on what was discussed, it wouldn't be hush-hush otherwise, but a bunch of heavy-hitters held a Gathering before the event started.

One personage notably absent was Sir Richard Branson. This was a big enough event in one of his fields that his absence seems more than just a scheduling conflict.

A quick prediction: the first boots on Mars will be worn by Sir Richard. He is the only entity on Earth with the combination of drive, capital and daring to realistically do this. I predict his landing within 15 years, possibly even before NASA gets back to the moon.

My Lesson Four: Being in the right place at the right time is vital.

The most interesting phenomenon at the XPrize Cup and ISDC '06 has been the earthquake that I call Generation Get Space Done. These new faces, generally young and enthusiastic, are a surge of people willing to work together to make things happen. Some are academics, others business types, entrepreneurs and the adventurous. None seem stymied by the politics that cause graybeards to tumble off chairs. They actively seek cross-discipline contacts and want to "Do these things in this generation." The oldest in this mindset might be 45 (and the young-at-heart always count) but the vast majority are under 30 and about to make history.

Generation Get Space Done shares something in common with the wealthy patrons who have bankrolled the private projects: They all have the Vision Thing. They don't wake up in the morning thinking "Oh no, not another day." They wake up every day expecting to change the world. The billionaires and mega-millionaires providing macro level funding for the larger efforts can not succeed without the technology and innovation that Generation Get Space Done is creating.

We could go to Mars essentially now with Russian tech backed by someone like Sir Richard. It would be equivalent to the ancient shaman who could cross oceans - you might make it back, you might not. New hardware, practices and nonlinear use of technology from other fields will enable this to be done safer and repeatably. High technology, smart design and the purchasing power of free markets are enabling this. Those with the Vision Thing all seem to understand this. Those with the drive but not the Vision fall of chairs and Beavis people with their boom-mics.

Whatever your talent or skill, everyone with the Vision Thing brings something to the table. Do you have it?

My Lesson Five: Enthusiasm can count more than launch contracts.
