What would you do if you were in charge of a billion-dollar satellite that was spinning out of control? In 1998, NASA and ESA engineers had to solve this exact problem. How did they avert this disaster?SOHO is our Pin of the Month!

there is no proof the sun is a giant nuclear furnace, and comets arent loose snowballs. if they were they’d never make it that close to the sun and survive. that is all.
You’re not first
If we figure out what dark energy is can build star ships. What do you think of the way of time travel that can only go back as time is moving forward . and over vast distances
Did that person get fired for their BILLION dollar “oopsie”?
So… Even the sun has corona…?
Hi
Sun is for me a Miracle , Still Burning after all this Billions of Years or who knows how long
Would have been better with a different reader.
wow
Oh hey John you missed step 5.
John: Oh crap… It’s not a big deal though right? I mean it’s one step out of like 400, no one will notice right?
Boss calls John into office. So John, I’m sorry to tell you that due to resent events we are going to have to bill you for that mistake. Don’t worry though you still have your job.
John: Ohh *wheew* you had me scared there, how much is the damage?
Boss: Hmm let me see *flips through book*, ummm… $1 billion.
Woah the sun has Rona 😬 no wonder it’s been warming up 😂
fIrST
The SOHO pin, including a basketball background
You should do a video on the person that pressed that button. Are they still working for Goddard? What were they feeling when he or she realized that it was their fault.
f it… i’m the second…
you heard it right, corona came from the sun
I’m going to be the first human to stand on the surface of the sun.
No, I won’t burn up, see I’m going at night.
now we need to know more about the parker probe!
Citizen scientists find the comets by perusing the automatically uploaded pictures. It is not easy, but there are instructions for those interested in trying their luck.
I have a pigeon linebreed I’m working on and they’re all named after space probes. I know the next peep’s name
A gyroscope is, originally, a spinning disk on a stick. A reaction wheel is a spinning disk on a motor. Kind of funny they hadn’t thought to combine them before
Sees the corona? Point it back at earth, we need to know who’s got it! 😉
1 dislike from the engineer who pushed that button.
SOHO is mainly a ESA Spacecraft, it just has a few NASA instruments onboard
how’s everyone’s day
Idk why but i legit got so hyped when he said soho survived. It was like storytelling at its finest
I have a background in electrical engineering, and I still find it it fascinating how they manage these problems.
I don’t know why, but I love hearing about satellite missions getting extended. And the fact that this one has been going for about 10x longer than planned is just mind boggling.
Serendipity: a fortunate mistake.
It was the Arecibo observatory who found SOHO went is was out of control.
Today Arecibo collapse because of NSF funding cuts.
SOHO SDO and the stereo sats are pretty amazing
Especially with the ramp up to solar max in the coming years.
Excited for another great fireworks show!
“Enormous tornadoes on the sun.” Ok, you got my attention.
How am I this early?
Also, Stellar Tornadoes are amazing. I would say that they are cool, but they’re literally not.
271! Still feels early to me 😊
Hi
The spacecraft was doomed to burn up in the Sun until a scientist had a *bright* idea
Soho is a bad mofo
*Not first!*
Plasnado would be a much better movie.
Hallo
are the videos of the sun in real time?
At 5m33s into this vid, when comets are being discussed, why is the tail of the comet trailing directly behind its orbital arc and not being pushed more perpendicular to the sun itself ?
So you could say the wheels in the sky kept on turning. Quite a journey, Hank.
How that comet at the last minute (5:40) left a trace behind after passing near the sun? shouldn’t it be ahead of it?
Should rename it Icarus
Thehoe
S upremely O utlandish
H armonious O utcome 🖖
Pins!!!
Is a SOHO 2 planed?
Hello Hank!
12th
SOHO is awesome
Be like SOHO
Hell yeah. Science.
Reminds me of my wedding night
0:56 the WHAT
me: “last night I had a nightmare that my mom died of covid19 and I woke up in cold sweats. this stuff is getting to my head, better to try not to think about corona too much…”
Electroboom: “We’ll create an arc by exploiting the CORONA discharge…”
me: *cringing*
Hank: “…to study things the Sun’s *CORONA*… ”
me: *cringing* “whyyyyyyyy? tu quoque Hanke!”
193rd
Very cool! Neat to see a mission I work on a bit featured here.
Oh no, the Sun has corona? 😢
I couldn’t find a SOHO version of this, so this will have to do.

Ever have one of those revelatory moments where you realize something that you’ve already known but just hadn’t really thought about until now? And somehow it feels just as cool as if you hadn’t known about the thing before?? I don’t know why this video did it, but like. Man. The sun is literally just an incomprehensibly massive, ongoing explosion. Every time you look at the sky on a clear day you’re seeing a nuclear explosion. A nuclear explosion that all life on earth is powered by! This is such a “Stoner At 3AM” revelation, but gosh, space is cool.
This is the same satellite which predicts auroras, right?
thanks to that one misstep.
Great video as always.
I request to do a video abt Arecibo Radar telescope, from conception, construction to sad death. It would be great.
This year has really gotten to me. I heard ‘Study the sun’s corona’, and for a second I thought, “Oh no.. the Sun has the ‘rona!”
SOHO IS SO COOL!
Spinning, that a good trick
Problems always happen during routine maintenance!
What would be really cool is an world-of-worship kind of game wher you control a battle spaceship with little propellers and a huge array of tools to catch solar winds.
So like that Progress cargo vehicle that lost attitude control a few years ago on its way to the ISS?
Thousands of little comets…sounds so poetic.
soho is designed to explore corona
covid 19 – are you kidding me bro
now that’s what I call a fine piece of equipment!!!
I love a happy ending
I wonder what instruments they will use to stabilize the satellite when one of the spinning wheels go bad on the next generation of satellites.
What if you messed up at work… but your work was SPACE?
Not only are solar tornados frighteningly awesome, but “The Solar Tornados” would be an awesome band name!
Gees, what speeds did that comet hit grazing the sun like that?
Little did we know… someone based a seminar on little did we know…
At 4:30, so we have a satellite relying on an improvised solution that’s better than the original one?
I took some of those pictures! I worked on SOHO in 2013-2014!
Cool – I like it when a plan comes together beyond our expectations in spite of our best efforts to screw it up.
SOHO is even in movies.
Nasa: “Hey, so you know how you were gonna retire after 2 years?”
Soho: “Yeah, I’m really looking forward to that.”
Nasa: “Yeah… Actually things are going so well we’ve volunteered you for five more years! Isn’t that great? Soho?”
Soho: “Not if I have anything to say about it…”
Nasa: “Heeeeeyyy Soho!”
Soho: “…What.”
Nasa: “So good to finally reach you! Wow crazy what happened back there, so random! Anyway, we’ve fixed the problem and we’ve volunteered you for _twenty_ more years!”
Soho:
Great info about SOHO.
How about a SciShow about the origins, life, and sad death of the Arecibo dish?
“How do you lose a sattelite?!”
“You forget to cherish her.”
Brohos before SOHOs I guess
Gyroscope is done, we are doomed….
No captain, activate the spinny spinny!
“Tornado’s on the sun” is a phrase people that live in tornado ally are probably not gonna want to hear or see in cinema… but I want that movie made lmfao!
yolo soho. So crazy, the world is spinning.
My beloved SOHO! I used data from SOHO in the late 90s for my bachelor’s degree in physics. I even have a poster of SOHO somewhere!
This is the most “Trust me, I’m an engineer”- war story ever
Arecibo is the extremely powerful radar telescope in question
Maybe the real treasure was the satellite piloting methods we learned along the way.
“And this new technique turned out to be even more precise than SOHO’s original gyroscopes”
PPPFFFFFFTT
How to save a spacecraft spinning out of control?…
TARS: “it’s not possible”
Cooper: *_”No, it’s necessary”_*
