A once-in-a-lifetime Opportunity: NASA bids emotional farewell to its cocky, hardworking RC science car on Mars

SpaceX's Crew Dragon shows up at pad 39A, nearly 8 years after the last Shuttle left


RSD (Rapid Scheduled Disassembly)

The in flight abort is scheduled for later this Spring and will use the same DM-1 capsule. The first stage has yet to be identified. The plan is to demonstrate the abort at MaxQ, triggering the sequence in the most stressful part of the launch profile. I've heard two versions of how it might happen. First, just send an abort command at MaxQ and see what happens. Second, detonate the first stage (tricking the AFTS or through planted explosives?) at MaxQ and let the abort computers do their thing. It'll be fireworks whichever method is used.

Suunto settles scary scuba screwup for $50m: 'Faulty' dive computer hardware and software put explorers in peril


Serious Divers...

Plan their dives and then dive their plan, always go with a buddy, don't exceed the tables, and abort the dive when things start to go wonky. Computers are nice backups, and that's it. They can preserve the history of your dive to download later. Anyone who relies on their dive computer to tell them it's time to come up is too dangerous a diver for me. Algorithms are notoriously different between different manufacturers, and when the diver can pick how aggressive they want the algorithm to work, you're just cheating death. [Note: If you're a commercial/tech diver, ignore the above, I'm talking to all us recreational divers, you lot get my respect for the dangerous working conditions and computers are absolutely necessary].

Side note: If you ever get the chance, diving in the Red Sea is glorious...not Sharm-el-Sheikh, but down further South along Saud Arabia...lots of reefs that are rarely (or never) visited by divers. Wish the Kingdom would open up tourism for divers, was lucky I had the chance while I was living there.

Re: It always pays to carry a Micro-Uzi in a shoulder holster

Can't speak for @Jake, or his particular country, but if Afghanistan and other fights are any indication, a well-armed and determined populace will tie up any army and cause all kinds of trouble. Eventually, said army will withdraw because the only alternative is genocide. That's why Afghanistan continually kicks invading armies in the 'nards, including the current scenario playing out. The American forefathers had just gone through such a scenario with only 30% of the population for independence. They knew very well that a well-armed population is much more powerful than any army, the obvious exception being use of weapons of mass destruction/genocide which happens to be politically unpalatable in these modern times.

Big Falcon Namechange for Musk's rocket: BFR becomes Starship

Re: Starship

Let's hope "Starship" will be the class name and subsequent ships will be named either for rock bands, subatomic particles, celebrities with sex tapes, or failed sub-orbital balloon ventures (LOHAN anyone?).

Re: Dragon vs Orion

Crew Dragon and Orion are already optimized for different roles. Dragon for LEO, short duration missions, acting as a lifeboat for a few months before deorbiting. Orion for long-duration, beyond LEO missions where the radiation protection and support system requirements are much more critical. You could use an Orion for runs to the ISS (common docking mechanism, I suppose), but that's like taking the Class A motorhome RV to Tesco for a milk/bread run. A Dragon run around the Moon has been proposed and could be a thing, I suppose, but it's really stretching the limits of the life support/protection systems to do that. That would be like taking the family of four across the USA in a Ford Escort, possible, but the memories made probably won't be of the sights as much as the smells. But, if Elon's looking for a volunteer...

Re: RE: AC

Ejection seats are not "tuned" to a passenger. They are designed to save a person fitting a range of height/weight values. That said, a 0/0 system (0 height/ 0 forward velocity) is one hell of a ride and can/has done damage to vertebrae, spinal cords, improperly placed arms/legs, etc., sometimes forcing fighter pilots to switch to trash-haulers after an ejection. It is seen as slightly better than dying.

Re: I have always thought...

I imagine an call center guy taking these and asking the following questions before dispatching help...

“Sir, please calm down, I cannot understand you when you’re screaming in pain.” (Picks his nose)

“Is this emergency a result of YouTube, Snapchat, Reddit, Instagram, FaceBook or other social media posting.”?

“Were the words ‘Hold my phone’, ‘Hey y’all watch this’, or ‘Hold my beer’ uttered by the person or persons in need of help”?

“If you answered in the affirmative to either of these conditions we are unable to assist you at this time, have a nice day.”

Have I Got This Right?

<quote>Yashar Hezaveh, co-author of the paper and researcher at Stanford, told The Register: “It’s hard to say” what features the CNN learned to extract to arrive at its output answers.

“In fact we don’t really know. As we show the examples to neural networks and ask them to make the correct predictions, they may find very complex features in the data that they can use for their predictions. We can sometimes look at the features, but they will be highly non-intuitive.

“I usually think about it like opening the brain of someone and looking inside it: it doesn’t tell us much about what the person is actually thinking about or how they see the world.”</quote>

They're using results of a computer analysis but don't understand how the "neural network" got the results? How do you replicate and/or validate the conclusions/results independently?

Moon Space Station?

The other bit of odd news in the article was that JAXA will use a NASA space station orbiting the Moon in 2025...since there is no firm plan for this beyond a few PowerPoint presentations, and 2025 is only 8 years away.

Re: Issues With Automated Traffic

1) Automated traffic would, by definition, be remotely accessible, as each vehicle will be coordinating with all the other traffic within a certain radius.

2) Traffic lights in my city are automated at the intersection, not from a central traffic control operation. People spoof the signals already, getting straight green lights (though only one case has been reported in our city).

5) Why leave this to some judge to legislate from the bench? We need to figure it out long before then.

6) So you'll be the sheep that lets a programming issue get him $$$ in fines and tickets?

7) LOL, we don't make it mandatory in a number of states to wear a helmet or protective clothing while riding a motorcycle, why would this be any different?


Issues With Automated Traffic

1) Some country will find a back door and program 150,000 head-on collisions at the start of hostilities.

2) Some script kiddie will not want to go to work/school and will hack the city traffic to cause gridlock

3) Some late for work/soccer practice idiot will buy a 1-time illegal "speed pass code" for $5 (same as a Pepsi) and cause chaos for everyone else as he/she streaks through traffic.

4) Adjusting to ever changing road conditions (degradation, repairs, upgrades, weather, rules and marking changes from one locality to another, etc) will be ginormously challenging.

5) How will liability be assigned for fatal or injurious accidents?

6) If the system doesn't see the speed limit change because a tree limb blocked the camera(s), who pays the ticket?

7) Will some gov't agency have access to your vehicle's information so they can trace your whereabouts in the past or even in real time? Is that a violation of either privacy rights, or self-incrimination protection?

Just some issues to think about...

Fake invoice scammers slurp $5bn+ from corp beancounters – FBI


They claim pay, too...

My company (of 45-50 people) was sued for back pay from wrongful termination by an individual who never worked for the company, in a state we'd never worked in. We went to court with the documents to prove our company had never employed anyone by that name. It's happened before to us and turns out it's a fairly common scam. Whenever the company doesn't settle, the claimant just says: "It was an honest mistake, I mixed up (whatever)." The judge dismisses the case and it's too expensive to pursue charges (prosecutors are not interested in such small fry).

US Navy runs into snags with aircraft carrier's electric plane-slingshot


Re: We all need less stress...

IIRC, the first USN attempts at catapults were with hydraulic systems, until the RN came up with the steam version. Apparently, steam can be "ramped up" to prevent instantaneous load on the aircraft (though it's still pretty damn quick), unlike hydraulics. EMALS probably has the same issue in programming the load on the catapult, ramping it up quickly enough to launch a fully loaded aircraft while keeping stress on the airframe below ratings.


Re: Has surge recxently been redefined & I missed it?

The combat rating is 160 sorties/day, normally conducted in a 12 hour window. The remaining 12 hours are used for repairing said aircraft, performing inspections, and readying for the next flying "day" (which could be at night of course). This also allows for inspection and repairs of the launch and recovery systems, and other shipboard systems used to support flight operations.

The surge of 270 sorties/day is for short periods only, usually a few days. After that, aircraft and ship discrepancies and inspections build up enough to pull out of combat ops to repair/refit/inspect.

Re: Wedding Parites

While living in Saudi Arabia, I heard my Saudi counterpart's smartphone on speaker with sounds of gunfire. I joking asked "Family reunion?" His reply: "Yes! We were celebrating a wedding!" I asked if they fired the guns in the city, and the answer was yes, they did, but they used the small bullets as they "disintegrate in the air". I corrected him, but not sure if it really sunk in...


Base Names

RAF put their service designation before the base name, the US does it opposite. So, RAF Lakenheath works for the UK, but it would be "Creech AFB in Nevada", or " the USAF's Creech Air Force Base in Nevada"; or something similar.

Re: Battery recycling

That's EXACTLY what happened to the US in the Gulf War. They brought all these recycling containers, had everyone trained to separate and segregate properly and thought the Saudis would be quite happy. They were quite pleased with themselves. Then, some TCNs (third country nationals, probably Bangladeshis) just picked up each container, dumped it into the common garbage truck, and drove off to the dump. LOL!
