"Here at SciShow, we use the metric system of measurement, because let's be honest, imperial units are just plain stupid."
+Ze Rubenator Funny thing is, though, that "the rest of the world uses only the metric system" is dishonest. Most all places in the world use some mixture of the two.
+Azathoth43 Nope.
Parts of Europe use a mixture of the two, and so does Canada. But throughout Asia and Oceania (including Australia and New Zealand), metric is _entirely_ the only system used.
God bless America!!!
+Ze Rubenator Americans use the Imperial system as long to be ruled by the British.
+Azathoth43 Sweden don't use it at all. A lot of my friends have no ide about how long foot or yard is.
there's something poetic about the Japanese making aerial reconnaissance on December 7th - "a day that will live in infamy"
The Akatsuki probe worked out exactly like every mission I've ever done in Kerbal Space Program. "Shit, I missed and I'm now orbiting the sun. Well, let's just speed this up for 20 years and I'll get close enough to try again."
2:00 There was a crewman whose job was to fuel airliners. When Canada switched from Imperial to Metric, he didn't covert the gallons to liters and gave the plane only about half the fuel it needed. Compounding this, the fuel gauge that physically measured the amount of fuel in the tanks was broken. Instead they used a system that measured fuel use and calculated the amount of fuel left in the tanks.
This system worked fine, but it depends on the amount of fuel value at the start to be correct.
As a result the plane ran out of fuel about half way to it's destination. Fortunately the airline pilot on the flight was also a recreational glider pilot. He used all his glider skills (including the side slip) to land safely. Before this, no one even knew how well a plane that big would glide, not that it even COULD side slip.
Side slip is a way for the pilot to slow the plane or to steepen it's rate of decent without speeding up. It is usually used in smaller planes if the plane is to far above the glide slope to land safely. It involves using the rudder to "crab" the plane in the direction of flight, creating more drag.
Fantastic story :D
Props for adding more detail about the MCO than I usually see! For anyone that wants the more questions answered, like why they didn't catch the error sooner, or why they didn't see it was off course (they did), here are some more details from the Mishap Investigation Board's full (Phase I) report[1]:
The root cause *is* identified as "Failure to use metric units in the coding of a ground software file, “Small Forces,” used in trajectory models" but it also lists 8 contribution causes. Considering the root cause of the mishap as stated, in isolation, one might conclude that if mixing units is bad, all systems should be required to use consistent units throughout. And yet, that has not happened in the spacecraft industry. Instead, missions are moving towards using Commercial Off-The-Shelf (COTS) components wherever possible, which means that the component is accepted as-is, without updating the software to convert the units of various inputs, outputs, or parameters. Converting the units is not even a big deal, it's mostly a matter of communicating to the cognizant engineer what units are in use where.
As you said, (quoting Wikipedia) "A contractor (Lockheed Martin) failed to implement it's software to the interface specified in its contract. Specifically, their software produced impulse measurements in pound-seconds instead of the required newton-seconds"
But, when you said "then the mission team sent the craft to what they thought would be a safe orbit" a more complete description of events would be (also Wikipedia) "When two navigation engineers noticed a discrepancy between the calculated and measured position of MCO, their concerns were dismissed. At one point, and additional Trajectory Correction Maneuver (TCM) was considered prior to the failed orbit insertion, but not performed."
And, for good measure, to quote the contributing causes (from the report):
1. Undetected mismodeling of spacecraft velocity changes
2. Navigation Team unfamiliar with spacecraft
3. Trajectory correction maneuver number 5 not performed
4. System engineering process did not adequately address transition from development to operations
5. Inadequate communications between project elements
6. Inadequate operations Navigation Team staffing
7. Inadequate training
8. Verification and validation process did not adequately address ground software

That probe is gonna buzz Venus yelling "Tora Tora Tora"
Why do the Japanese always plan things for Dec 7th?
+PhazonSouffle lol they didn't choose that date, they simply calculated for when the orbits aligned, and that just happened to be the date.
+PhazonSouffle I was thinking the same thing
+PhazonSouffle ahhhhhhhhh, I was waiting for someone to say that!!!
It'll be a slightly more awesome day now. it has a lot of catching up to do.
***** Most people probably don't know the date. I'm just a fan of Tora Tora Tora.
So Japan is planning a sneak attack on Venus this year... they seem to like December 7th.
I have no idea why the way he says "well, they... _tried_ to send it. But... they missed" at 3:06 cracks me up.
The most epic fail to me is still the Venera 14 mission to Venus. The probe landed no problem and ejected it's lens cap, but unfortunately the lens cap ended up right underneath the instrument that was supposed to measure the surface.. so the instrument measured the lens cap instead!
Huh. Hank, you look different.
lol
+Millennia0007 Hormone Replacement Therapy.
+rhemorigher Man what's John going to say when he sees him on Friday?
+Millennia0007 Who the eff is Hank?
+Chris C Hank is a is a mass of incandescent gas A gigantic nuclear furnace Where hydrogen is built into helium At a temperature of millions of degrees
We must prevent Akatsuki from reaching Venus or they'll be able to cast Mugen Tsukuyomi on the world.
Hearing about the Akatsuki mission being salvaged made me really happy for some reason
I really wish you'd label links
"Hank describes..."
Orly?
I find it funny that the American colonies wanted nothing to do with the British Empire and violently seceded...but they hold on to the imperial units like lovers' hands during the honeymoon phase. This may say something about human nature.
+E “Anonymous Nerdfighter” Hernandez Americans don't use imperial system because of a secret love for the English. A massive number of Americans don't even know it is English. It is economically inefficient for a national switch to SI. But yes, like a rebellious teenager, America should hurt itself by switching to something their parent hated.
+E “Anonymous Nerdfighter” Hernandez The alternative is French. We used to like them, but they got to be rather annoying.
+Madra Actually, the cost thing about switching is hugely overstated. Most of our production machinery is already metric. People who can't cope with reality then bolt on converters to units nobody uses.
it would be nice if you're links had descriptions as to what they pertained to. Great episode again though :)
Description says "Hank"... Hank what happened to you??
so did akatsuki accomplish its mission?
Yes, it's a lot further away than initially planned though but is on an elliptical orbit so at some points during the orbit it gets nice and close so it can take some good pictures.
Asking the real questions!
Yes, it's in orbit and it's sending valuable data and photographs.
nope naruto fought back
cyka lol, i had to pause and looked for naruto comments, found ya
The ESA Beagle 2 mission also comes to mind, interesting list though :)
Apollo 13 should have been on this list.
The mission failed but they brought the crew back alive.
Akastuki will finally reach it's destination, where it will most likely probably de-orbit someday, allowing all those aluminum plates full of names to melt, just as nature intended.
Hey SciShow, it'd be nice if you do an episode on Tsiolkovsky. If anyone needs any convincing on why he is awesome and deserves an episode - the most basic and fundamental equation in rocketry is aptly called Tsialkovsky's equation.
I imagine the remains of the Soviet Lunar Lander are still there. I wonder if one day we'll be in a position to recover them. It'd make a good museum piece.
I can't believe they actually messed up the imperial / metric thing with that Mars probe. Can you imagine when they suddenly found out? Short silence in the mission control room followed by a huge chorus of "D'oh!" lol
The lunar lander mission reminded me of the lunar lander game, equally stressful
No Four-inch Flight? No Columbia Disaster? Missing the big stuff here! Whatever, still a great video!
Challenger, SpaceX and that Apolo mission that went major bad.
Reed's voice is awesome
3 epic buzzfeed titles.
I learned nothing after hearing Akatsuki because I was like SASKUEEEE
And this is why my videos always use the metric system.
Too bad in American math classes we still use English units. I'm glad science classes have changed though. Now we always use SI units and are required to learn the base 7.
We should build a Death Star that isn't that big
+Ricardo vivas Lego already has.
+ljmasternoob no like one that has a laser and that is at least two storys tall
Ricardo vivas
Trans Siberian Orchestra is close.
Luke and Han just took a few minutes too find and save Princes Leia. That would imply Death Star isn't that big. Or just bad writing, but that would be ridiculous.
Frahamen
The Force acts as a GPS sometimes.
Metric is good because the meter is the distance the light travells at a short distance of time. A litre is just (meter/10)^3, or dl^3. One litre of water (at a spesific temperature and pressure) is a kg. Bam. You have defined 3 different units by measuring how far the light travelles in a spesific time and water at some temperature. And then it's just multyplying and dividing with 10, and then you got some units to work width. Simple as that
I watch this in Technology Class!:)
( ͡° ͜ʖ ͡°)// hi
Hank?
+CaptainOfGames This is what I was thinking.
Hank Green and Michael Aranda hosts Scishow.But more people hosts Scishow Space.
I have no problem.Do yous(both of you)?
We were talking about how it said "Hank" in the description.
Akatsuki was already in a stable Venus orbit by the time I saw this!
Personally, I think imperial measurements are pretty useful for casual conversation. The units (especially temperature) are relatively easy to grasp. For instance, 0 degrees F= really cold, 100 degrees F=really hot, while 0 degrees C=really cold, 100 degrees C=dead. Also inches are a pretty good approximation of a finger length, feet are... well, feet.
But outside of that the imperial system is absolutely terrible. I've used it my entire life, and because of the American school system I was never really taught how to use the metric system.
TL;DR: Imperial is good for describing things using "relatable" units but it gets old REALLY quickly when you're trying to use it seriously.
Captain hindsight! We need you!
Gotta love automatic subtitles: "Take the Akatsuki probe, which Japanese Space Agency JAXA sent to penis in 2010, while they tried to send it, but they missed" -_-
Give us more space news i love it
I am so impressed with all the men and women working for space programs. They launched a space probe to Venus, got it to orbit the Sun instead, but still managed to calculate the way to get it back to the planet. The sheer amount of math involved must have been outstanding. I know most of it is run by computers, but by god, someone had to program those. They are my true heroes (the scientists, not the computers).
4:02 on auto captions when he say venus's
You are welcome
Bit if an "oops" in your animation, there.
That flavour of Luna probe had an upper stage... the legs got left behind when it came back to Earth.
let us not also forget Luna 23, which safely made it to the moon's surface, but tipped over soon after.
idk if any of these would be considered "epic".
+Don Williams When you launch something into space come back and tell everyone.
+Don Williams Hundreds of millions of dollars not epic enough for you?
I'm not saying space isn't epic, I'm saying that I thought there would be more epic space fails than a couple space craft going off course. Why so aggressive?
+Don Williams Because this isn't like a 200 dollar RC airplane crashing in the woods, these are missions people devoted a good fraction of their career to.
+Don Williams refer to: "Challanger disaster". It was like Transformers or 9/11 but real people died dude
Do we have any news of the Japanese probe coming back at dec 7? Like did it make it?
Why can't the WHOLE WORLD just stick to the metric units?
+boy638 Because America wants to be different.
'cause MURICA
+boy638 Why? Because the same reason you could never just randomly switch to another system of units. Without first converting to metric... Tell me, do you know what 14 miles is, or what 67 inches is? Do you know what 193 pounds is, or what 73°F is? I can grasp those amounts and intuit what they mean, without having to convert, or consciously quantify them first. I could not tell you what 9.3 meters is, or 783 km, or 68°C, or 78 kg without first stopping to convert or quantify those units.
As to some other's claims of the old imperial measurement system simply being "stupid", compared to metric, sure, it's not as elegant, but all those values were based on quantifiable bases that once made sense to measure from. It's simply another system, certainly not better than the quite elegant metric system, but certainly not "stupid" either. Just different.
did i say it was stupid? i just wished the whole world agrees to stick with one
+boy638 No you didn't... Which is why I said "As to some other's claims". I just did not feel compelled to reply to a dozen different comments. Isn't not paying attention to the small details why conversion errors between measurement systems occur in the first place.
2:19 And thus, a team of engineers were fired that day
There are two major groups of societies in this world:
-those who use SI, and
-those who have sent humans to the moon.
JAXA's Akatsuki entered successfully the orbit around Venus for its second attempt on December 7, 2015.
Apollo 1
R.I.P.
Rich Purnell must have been working for the Japanese on the last one.
My first ksp epic fail: Landing on the moon with a parachute.
+adri ahmad My first epic fail in KSP was trapping Jeb in Kerbin Orbit for 35 years (roughly 10 years on Earth).
+Nevan Lowe Did you use Life Support mods?
adri ahmad no
+Nevan Lowe fail in KSP? trying to suicide burn for a munar landing at 4km with 2 atomic rockets and a 150ton spacecraft.
Kroposman 230 Mun*
GET IT RIGHT!
NASA has a unit conversion fail after reaching the fourth planet from the sun again, meanwhile back on earth, metric system countries continue to successfully launch model rockets hundreds of meters into the air.
akatsuki makes me think of the anime that came out this year akatsuki no yona... man i love that series/ manga
Akatsuki. The moon plan failed, so now Madara is trying Venus.
Pounds and kilograms are not equivalent units. Kilograms measure mass, but pounds are units of force. The English system's kilogram equivalent is called the slug.
The description is wrong. This isn't Hank. This is Reid
2:06 lockheed? that sounds familiar! oh right! lockheed SR was the fastest plane in the world! I don't know if it got beaten yet
How can you not include Apollo 13 in this...?
I just find it funny that the optimal date for the Akatsuki probe's transfer burn is December 7th
Talk about coincidences...
any news of the JAXA mission? we are past the date of the orbital corrections. did it succeed?
JozefK78 Yes it did. long ago. see global.jaxa.jp/press/2015/12/20151209_akatsuki.html
It's funny that people in the world don't realize that Americans use both systems proficiently and are taught in elementary school. It's much like learning an extra language. I am just as comfortable with 1 system as I am with the other. Every single soda bottle in the super market is metric (save the 20 oz ones), the displacement in our cars is metric, our favorite WMDs are in kilotons and megatons, film for cameras have always been in metric, many firearms are metric, and all us military measurements are metric, every nutrition information chart on every single food item in the US is in grams, all electrical measurements (amp, volt, ohm, etc) are metric, our whole currency is base 10, gemstones are measured in metric carats, even illegal drugs use metric. I think the US is doing fine. MPH sounds cooler than Km/H, just ask Top Gear, acres sound better than hectare, and a foot is about as long as it's name implies. Having a colloquial system is nice. It makes communicating in a less formal setting more fluid and congenial, something Americans seem to care about in my experience. Also 100 sounds a whole hell of a lot hotter than 37.8. Making me think twice about forgetting my water. It may be old, primitive thinking, but shouldn't life be easy if possible, and not full of calculating things in base 10. How far away is that? About a mile.
#2 makes me wish to palm my visage.
Why is the challenger explosion not on this list? That seems like an egregious oversight...
What about the 1986 Challenger Explosion, I'd think that should have been on this list, I remember sitting in class watching that happen.
The whole Akatsuki thing sounds like something from Kerbal Space Program.
the title looks like FailArmy
Mission failed we'll get them next time
there are two types of people
1)the ones who use metric
2)the ones who crased a multi-million dollar spaceship on mars because they don't
michael papadopoulos No...
2.) People that left footprints on the Moon
"Space missions are difficult. Hank describes three epic space mission fails!" I don't think this is Hank :)
So sad and painful to listen!! Getting to the destination just to crash or burn D: it's like being a runner on your first Olympics and trip with your own shoe lace a foot before the finish line... and breaking both legs so you can never run again lol and that's why you use metric C:
im totally amazed that Japanese probe was salvaged in the way it was
Akatsuki means dawn.
probably named such because Venus is visible from earth in the early morning
that's why it's also called Lucifer.
I still cannot get over the fact that American engineers still use Imperial units. If you are trained as a scientist in the US, you check your feet, pounds, and Fahrenheit at the door and live in MKS. If you continue on to grad school, you move into cgs. I know engineers in the US are required to take physics courses; I've taught some of them!
good stuff..
"they missed"
owned
No mention of Beagle 2. Good... good...
"All those names and messages will finally reach their destination."
On Venus.
Where they'll be crushed and melted by the atmosphere.
Then, of course, there's the biggest space mission failure of all time: not sending ME into space!!!
:_ (
I hope they're able to save the Akatsuki mission.
The United States tried to convert to metric once, the issue was that it was optional for the states. No one wanted to have to learn a new measurement system and change everything. So after a few years of little success the project was scraped for nation wide use of the metric system. Most scientists and engineers are forced to learn it though and most science classes will teach their kids metric as well.
The issue isnt America being dumb, the issue is having the option not to learn it when theres no real point in most of our lives,
We probably would never have reached the Moon if not for the Apollo 1 fire. There were so many things wrong with the capsule it was not space worthy. Bad record keeping by the engineering team, poor wiring techniques and too much flammable Velcro made the command module a death trap. They were forced to redesign the it. The result was nearly an entire new spacecraft.
Space seems to be very expensive to explore!
I'm American, and its a nightmare trying to convert measurements in my head just to keep up with the world :(
science* metric system is science language. And although it's to my advantage, I know the struggle of having to convert whenever ppl talk about miles
Im in Australia, although its all metric now it used to be imperial long time ago, well before I was born. But still I learned most conversions values in my head as many of my interests and hobbies with cars and engineering knowledge is US based its pretty much second nature to me now. How is this for fun, all my cars are metric except the engine and drive-train is mostly American based. So there are parts that are metric and some that is imperial. Even the engine itself that's entirely US was built in a period in the US where you guys started using metric so it literally has half metric bolts and half imperial lol.
Nick Walker is
Nick Walker me too
Well, the difficulty might be a sign the time has come to follow the rest of the world into the wonderful realm of rationality and scientific literacy.
the most epic fail was that early apollo mission when they lost that guy that was supposed to go around the moon but overshot... they didnt have any deep space scanners back then they have no idea where he went
+Lone Wulf Was this a movie or something?
Some might not think those were very epic, but if you work in the industry and science behind the fails, you'll understand the facepalm and headaches and indigestion these things cause.
please, lets all join together as brothers and sisters, and lets put an end to the vile imperial unit system once and for all.
Hank! What happened to you? You look like that SciShow space guy now.
Pretty much the Akatsuki would use Venus for its Moon's Eye Plan. Also, it's December 7th so you know what that means. SURPRISE MUDAPAKA!!!
I would of thought Apollo 13 would have been here.
or Challenger
+joe kickass have*
Mike Beckers What are you correcting?
I would have thought
"I would of thought" is still a grammatically sentence
Even the smartest people have trouble with the maths sometimes.
I wonder if they were able to "save" the probe.
Akatsuki means "dawn", and it ended up around the sun :D
Haha! Turn on subtitles at 4:03
4:18
Me: What, like destroying Konoha?
That animation of Luna is oversimplified. In reality, it has an upper stage that lifts off, and leaves the base. Similar to the American LM.
Also, damn, Japan's space program is _intense_. Hayabusa was like that too.
HANK GREW A BEARD!
