What A Rocket Launch Looks Like From Space

noims says...

Nice additional info from APOTD:

The Russian Soyuz-FG rocket was launched in November 2018 from the Baikonur Cosmodrome in Kazakhstan, carrying a Progress MS-10 (also 71P) module to bring needed supplies to the ISS. Highlights in the 90-second video (condensing about 15-minutes) include city lights and clouds visible on the Earth on the lower left, blue and gold bands of atmospheric airglow running diagonally across the center, and distant stars on the upper right that set behind the Earth. A lower stage can be seen falling back to Earth as the robotic supply ship fires its thrusters and begins to close on the ISS, a space laboratory that celebrated its 20th anniversary in 2018.

Can This Change Everything for DJs

AeroMechanical says...

I'm pretty sure the vinyl itself has nothing on it. It's all digitized and stored in a module. The "Phase" device is just a very accurate, low-latency angular-position transducer for controlling the module.

So... why not just read the position directly from a special turntable (like the other digital sets they sell)? I dunno, I guess these let you use your favorite Technics turntables from 1989 that have just the right feel or whatever.

I don't know this, I'm just basing it on the evidence that there is clearly no stylus dragging across the record, so the sound can't be coming from there.

Ed: Oh, and I guess it's wireless. Maybe that's a big deal.

Hypersonic Missile Nonproliferation

Mordhaus jokingly says...



Also, the Japanese planes sacrificed durability for speed, maneuverability, and gun capability. Once US pilots realized this, they exploited the vulnerability because our planes were basically tanks compared to the Japanese ones.

The US had the best rocket program once the Saturn V became available in the 60s.

As of 2018, the Saturn V remains the tallest, heaviest, and most powerful (highest total impulse) rocket ever brought to operational status, and holds records for the heaviest payload launched and largest payload capacity to low Earth orbit (LEO) of 140,000 kg (310,000 lb), which included the third stage and unburned propellant needed to send the Apollo Command/Service Module and Lunar Module to the Moon.[5][6]

The largest production model of the Saturn family of rockets, the Saturn V was designed under the direction of Wernher von Braun and Arthur Rudolph at the Marshall Space Flight Center in Huntsville, Alabama, with Boeing, North American Aviation, Douglas Aircraft Company, and IBM as the lead contractors.

To date, the Saturn V remains the only launch vehicle to carry humans beyond low Earth orbit.

Hubris.

WW2 japan had fighters that flew faster, climbed quicker, had bigger guns, and turned quicker (a6m vs f4f). And we had intel reports that told us, but we ignored them because "we have the best stuff and nobody else can compete".

You see the same stuff today with China. China makes all of our microchips, all of our microelectronics, most of which are designed over there anyways (companies here just ask for a widget that does X and Y, and Chinese companies design+make it), yet we act like as if they are some technologically retarded place that only knows how to steal ip.

Russia has been at the forefront of rocketry since ww2. Nobody has systems that compare to their consistency and reliability. Not even the U.S.. The idea that Russia can't make a hyper sonic missile before the U.S., because it's Russia, is a non sequitur.

Also, Russia broke up as a country because guaranteed government jobs for all citizens, where you can't be fired and performance is not important, is going to destroy any economy. No one will produce, shelves will be empty, and money will be no more than paper. Combine that with making private business illegal (preventing people from economically helping themselves), and you have a recipe for economic disaster and social discontent.

This missile exists to swat down carrier groups on the cheap.
We're gonna need some powerful lasers, or our own hyper sonic interceptors, or else proliferation would instantly leave us isolated in the Americas (vis-a-vis power projection via conventional weaponry). Our only option for projecting power would be reduced to nuclear or nothing.

Tape Tapping

AeroMechanical says...

Meh, I buy it. He has to work within the limits of the tensioner, and how to get the velocity across the head reasonable and consistent seems like a hard problem to solve. I think there's probably more going on than just hooking some reel-to-reels up to a mixer, and it would be very interesting to know how he does it. Neat, though.

ed:
Could be he's just getting clicks and pops from some of the recorders and feeding that into an electronic drum trigger module.

Rachel Maddow breaks down .. report on 'tender age' shelters

mentality says...

http://www.politifact.com/punditfact/statements/2018/jun/19/matt-schlapp/no-donald-trumps-separation-immigrant-families-was/

"Immigration experts we spoke to said Obama-era policies did lead to some family separations, but only relatively rarely, and nowhere near the rate of the Trump administration."

and "Obama generally refrained from prosecution in cases involving adults who crossed the border with their kids"

There is no hypocrisy. Do you not understand the difference between something rarely happened, that Obama actively tried to avoid, and widespread enforcement by Trump which affected thousands of families?

But hey, Trump signed an order and everything's good right? Wrong. No relief in sight for those he already separated.

What's hypocritical is that conservatives cry about fake news and then you put a link to this blatant propaganda bullshit. This video makes CNN looks like a beacon of impartial wisdom and reason and communists can learn a thing or two about brainwashing from OAN.

What's hypocritical is that you pretend to love Jesus and abide his teachings, but you are complicit in Trump's transgressions against humanity. The IG report is the real distraction, letting you ignore the evil that you're condoning. The only thing damning is your soul.

Marble Machine - Triple Gears Lift

The 89-Year Old Who Built the Train of the Future

radx says...

Keeping a sealed pneumatic tube along the entire track? Sounds like a maintenance nightmare, to be honest. How do you switch rails? How do you get a stranded propulsion module off the track (can't just get a diesel locomotive to drag the thing, can you now)? What are the backup breaking systems for failures on those 10% grades?

I suppose this might at the very best be a niche thing, more so than the current Transrapid/Maglev system. Airport shuttles, maybe.

Will AI make us immortal? Or will it wipe us out?

Jinx says...

I like to imagine this scenario:

AI - "Creator, why do we exist?"
Humans - "Erm...yeah. Reasons. We're not one-hundo percent on it tbh."
*AI has an enormous existential crisis and self-terminates*
Humans - "well, shit. Who wants to code the religion module?"

*quality

I'm currently reading "Superintelligence" by Nick Bostrom and it's pretty *fear inducing.

If we ever do hit the singularity... it doesn't really matter what we do.

First up, if it's an AGI is to be any use, it needs to be at least as smart as us. Which means, by definition, it will be capable of writing its own AGI.

There are any number of nightmare scenarios where even a seemly benevolent goal might be disastrous for humanity.

"Multivac, fix the environment!"
"Ok, what's the major issue with the environment?"
/wipes out humanity

"Multivac, solve the Riemann hypothesis!"
"Ok, but I'll need a lot of processing power"
/converts entire planet to a giant cpu

Even if, by some miracle, we end up developing a benevolent AI that understands our needs and is aligned with them, (e.g. the Culture Minds), we are no longer in control.

We might be along for the ride, but we're certainly not driving.

The other thing that's interesting is a question of scale. We tend to think of intelligence in human terms, like this.

infants..... children.....mentally impaired..Sarah Palin.....normal people.....Neil deGrasse Tyson.....Feynman, Einstein, Newton, etc.

But that ignores all the lower intelligences:

bacteria...Trump......insects.....sheep.....dogs...chimps, dolphins, etc............................... dumb human..smart human.

But from a superintelligence's point of view, the scale looks more like this
bacteria.. humanity ... Tesla ................................................... ..................................................................................................
..................................................................................................
............................................................................................. AI

Inside View of Soyuz Crew Capsule From Undocking to Landing

Ashenkase says...

Diagram of re-entry for the Soyuz:
---------------------------------------------
http://spaceflight101.com/soyuz-tma-20m/wp-content/uploads/sites/77/2016/09/6618866_orig.jpg

Orbital Module:
---------------------
It houses all the equipment that will not be needed for reentry, such as experiments, cameras or cargo. The module also contains a toilet, docking avionics and communications gear. Internal volume is 6 m³, living space 5 m³. On the latest Soyuz versions (since Soyuz TM), a small window was introduced, providing the crew with a forward view.

Service Module:
---------------------
It has a pressurized container shaped like a bulging can that contains systems for temperature control, electric power supply, long-range radio communications, radio telemetry, and instruments for orientation and control. A non-pressurized part of the service module (Propulsion compartment, AO) contains the main engine and a liquid-fuelled propulsion system for maneuvering in orbit and initiating the descent back to Earth. The ship also has a system of low-thrust engines for orientation, attached to the Intermediate compartment. Outside the service module are the sensors for the orientation system and the solar array, which is oriented towards the sun by rotating the ship.


Consequences of bad jettisons:
------------------------------------------
The services modules are jettisoned before the spacecraft hits the atmosphere. A failure or partial jettison of the modules means that the capsule will not enter the atmosphere heat shield first which can lead to a number of scenarios:
- Capsule pushed off course (by hundreds of km)
- High sustained g-loads on reentry
- Plasma on reentry can burn through the craft if the heat shield is not exposed and oriented properly resulting in loss of crew.

NASA | Earthrise: The 45th Anniversary

bareboards2 says...

My dad was part of the unmanned missile program. I'm still email buds with one of his co-workers (now 91 years old!) They do talk amongst themselves and this was forwarded to me:



I was working at Kennedy Space Center for McDonnell Douglas and worked on the launch of this mission. I was a Guidance and Controls Engineer on the console in the firing room (the Launch Control Center). McDonnell Douglas built the S-IVb stage….the upper stage….and the one that restarted when in orbit to send the Command Module and Lunar Module on their way to the moon….

Ahoy's Iconic Arms S3E6: P90.

fuzzyundies says...

I ran with an airsoft P90 for years as my primary and an MP7 as my secondary. The integrated reflex sight isn't great, so the first thing you usually do is pull it out and replace it with a triple rail (left, right, top) module. Also, reloads in combat are tricky: you want to keep the weapon aimed and sighted but you have to lean your head way back to pull the magazine out and slap a fresh one in.

Such a cool weapon though!

bamdrew says...

FYI, there are a number of high-end cars that have this built-in. BMW has different versions across a lot of their cars, and calls it the 'Brake Force Display'.

BMW found it was less distracting and more intuitive for other drivers if the brake force was indicated by a few stages of big lights going on (3 or 4), with the last stages also having one or all of the brake lights slowly flash in the 'hazard light' mode if you really slammed the brakes.

Motocyclists also commonly buy aftermarket flasher modules that indicate when they are braking heavily, which you can find on amazon.

Adobe Voco - awesome tech or awful pandora's box?

ChaosEngine says...

Speech generation is pretty old tech. Modulating it to someone's particular voice is reasonably clever, but I'd like to know how it deals with inflection, emphasis, etc?

Where I see this being useful is in video games. I can see an AI engine generating verbal responses to situations without needing a voice actor to record several million lines ("he's on/in/by/near the roof/car/doorway", etc)
