So Venus is my favorite planet in the solar system - everything about it is just so weird.

It has this extraordinarily dense atmosphere that by all accounts shouldn't exist - Venus is close enough to the sun (and therefore hot enough) that the atmosphere should have literally evaporated away, just like Mercury's. We think Earth manages to keep its atmosphere by virtue of our magnetic field, but Venus doesn't even have that going for it. While Venus is probably volcanically active, it definitely doesn't have an internal magnetic dynamo, so whatever form of volcanism it has going on is very different from ours. And, it spins backwards! For some reason!!

But, for as many mysteries as Venus has, the United States really hasn't spent much time investigating it. The Soviet Union, on the other hand, sent no less than 16 probes to Venus between 1961 and 1984 as part of the Venera program - most of them looked like this!

The Soviet Union had a very different approach to space than the United States. NASA missions are typically extremely risk averse, and the spacecraft we launch are generally very expensive one-offs that have only one chance to succeed or fail.

It's lead to some really amazing science, but to put it into perspective, the Mars Opportunity rover only had to survive on Mars for 90 days for the mission to be declared a complete success. That thing lasted 15 years. I love the Opportunity rover as much as any self-respecting NASA engineer, but how much extra time and money did we spend that we didn't technically "need" to for it to last 60x longer than required?

Anyway, all to say, the Soviet Union took a more incremental approach, where failures were far less devastating. The Venera 9 through 14 probes were designed to land on the surface of Venus, and survive long enough to take a picture with two cameras - not an easy task, but a fairly straightforward goal compared to NASA standards. They had…mixed results.

Venera 9 managed to take a picture with one camera, but the other one's lens cap didn't deploy.

Venera 10 also managed to take a picture with one camera, but again the other lens cap didn't deploy.

Venera 11 took no pictures - neither lens cap deployed this time.

Venera 12 also took no pictures - because again, neither lens cap deployed.

Lotta problems with lens caps.

For Venera 13 and 14, in addition to the cameras they sent a device to sample the Venusian "soil". Upon landing, the arm was supposed to swing down and analyze the surface it touched - it was a simple mechanism that couldn't be re-deployed or adjusted after the first go.

This time, both lens caps FINALLY ejected perfectly, and we were treated to these marvelous, eerie pictures of the Venus landscape:

However, when the Venera 14 soil sampler arm deployed, instead of sampling the Venus surface, it managed to swing down and land perfectly on….an ejected lens cap.

candid detail. my biggest project so far

hey happy new year

CG: DAVE?

TG: yeah?

CG: SOMETHING’S KIND OF FUCKING ME UP RIGHT NOW AND I NEED TO TELL YOU SPECIFICALLY ABOUT IT IN CANDID DETAIL.

TG: oh shit

===

TG: yeah whats up

TG: not too often i get to be the sole audience to karkats grievances

CG: PFF, BULLSHIT. YOU'RE PRIVY TO WAY MORE ABOUT MY GRIEVANCES THAN BASICALLY ANY OF MY SURVIVING AND PRESENT FRIENDS, BY A SIGNIFICANT MARGIN, AND YOU KNOW IT.

TG: yeah and im boutta add another im like broses up on that hill bundled up in a long ass list of things that make the homies upset

TG: lay it on me

===

CG: OKAY. SO.

…

CG: I’M KIND OF THINKING ABOUT JUST. US AND OUR BRO-DOM.

===

TG: oh

CG: LET ME FINISH.

CG: ALL THIS TIME I’VE BEEN FUCKING FORCED TO SPEND IN THE DREAM BUBBLES MADE ME REALISE SOMETHING, AND THAT’S THAT…

===

CG: THIS IS KIND OF RARE, RIGHT?

TG: what

TG: us

CG: YEAH! LIKE… THERE’S SO MANY THANKFULLY DEAD KARKATS I’VE HAD THE INSURMOUNTABLE GODDAMN DISPLEASURE OF FAILING TO AVOID THAT DON’T LIKE YOU, BARELY MET YOU, OR EVEN JUST DON’T CARE ABOUT YOU.

===

CG: IT’S THE RARE AMBIVALENCE THAT REALLY GETS TO ME. I ABSOLUTELY UNDERSTAND A TIMELINE’S KARKAT FIRMLY DECIDING THAT THEY HATE YOUR ASS. NON-ROMANTICALLY I MEAN. THAT HAS BEEN ME, FOR FUCK’S SAKE. BUT THERE WAS NEVER, EVER!!! A POINT WHERE I JUST FELT NOTHING ABOUT YOU AT ALL.

CG: EVEN WHEN I INITIALLY HAD THE MISFORTUNE OF SEEING YOUR DOUCHEBAG SPECTACLES YOU GOT FROM YOUR BRO ON THE SCREEN, I AT LEAST HAD A STARTER DISH OF SKEWERED CONTEMPT TO WHET MY APPETITE. IT’S IMPOSSIBLE TO IMAGINE NOT FEELING ONE WAY OR ANOTHER ABOUT YOU.

===

CG: ONE TIME I MENTIONED YOU IN THE MIDDLE OF A THREE-WAY ARGUMENT AND ONE OF THE OTHER KARKATS SAID "WHO?"

CG: "WHO?"!!!!

TG: now thats fucked up

CG: IT IS! AND THAT'S WHAT MADE ME FIRST REALISE THAT NOT EVERY KARKAT IS GETTING TO HANG OUT WITH EVERY DAVE, AND VICE VERSA. AND THIS IS GOING TO SOUND LAME AS SHIT IN A WAY THAT I’LL NEVER EVER LIVE DOWN, BUT. I FEEL BAD FOR THEM ABOUT IT! YOU KNOW?

===

TG: well you always feel bad about around and towards other yous so thats

TG: wait

TG: is or is not the nature of this moment of self-pity fuelled by malice anger disgust or any similar terms slash phrases

CG: I MEAN, FOR ONCE? DON’T GET ME WRONG, THE MALICE ANGER DISGUST ET CETERA IS STILL THOROUGHLY PERMEATING THE WHOLE ORDEAL. THE DAY I LOSE CONTEMPT FOR MY ALTERNATE SELVES IS THE DAY I GET TAKEN OUT BACK AND PUT DOWN LIKE THE LAME HOOFBEAST I’VE ALWAYS DREAMT OF BEING. BUT…

CG: I ACTUALLY JUST FEEL SAD FOR THEM, STRAIGHT UP. INDEPENDENT FROM TERMS PREVIOUSLY MENTIONED.

===

TG: damn

CG: AND THAT FEELS INCREDIBLY WEIRD TOO. I CAN’T EVEN ARGUE WITH THEM ABOUT IT, IT JUST MAKES ME FEEL THIS SHITTY, SHOCKINGLY QUIET… GRIEF? ALMOST? FOR THEM. GENERAL NON-TROLLIAN FEELINGS. AND EXCEPTIONALLY NON-STANDARD IN A KARKAT-TO-KARKAT CONVERSATION, AS YOU MIGHT HAVE GUESSED.

CG: BUT I KNOW IF I TOLD ANY OTHER EMOTIONALLY CONSTIPATED REFLECTION OF MY OWN FECULENT INNER FILTH TO TALK TO YOU, OR EVEN JUST LOOK AT YOU ONE TIME, THEY’D ONLY SEE IT AS ANOTHER PERSONAL AFFRONT. LIKE I JUST TOLD THEM "HEY, SHIT ALL OVER YOUR FROND AND SNIFF IT, IT’LL BE AMAZING JUST TRUST ME, ABSOLUTELY ZERO REASON NOT TO."

===

TG: you come up with the most potent mental images man youre the wordmeister of viscerally gross as hell vocab

CG: THANK YOU.

===

CG: AND LIKE… SHIT, I DEFINITELY WOULD’VE FELT THAT WAY BEFORE I GOT TO KNOW YOU! I UNDERSTAND THE INNER MACHINATIONS OF THOSE IMBECILIC NOOKSTAINS BETTER THAN ANYONE EVER COULD, DESPITE MY BEST EFFORTS.

CG: KARKATS UNIVERSALLY DECIDING THAT THEY JUST CANNOT LIKE YOU ON PRINCIPLE IS A CRISIS OF SHIT HAPPENSTANCES. THE HAPPENINGS ARE ALL OUT OF WACK, COSMICALLY.

CG: LIKE EVERY ME WRITHED OUR WAY OUT OF THE BROODING CAVERNS AND THE FIRST CONSTELLATION WE SAW PEELING THROUGH THE EXOSPHERE, TWINKLING IN THE REFLECTION OF OUR HUGE RED GANDERBULBS, WAS A PAIR OF SHADES GETTING COVERED IN GASOLINE, FOLLOWED BY A CONSTELLATION OF A LIT MATCH.

CG: A SIMPLE EQUATION WITH A VERY SIMPLE SOLUTION.

CG: A SYSTEMIC EPIDEMIC, IF YOU’LL PARDON MY BULLSHIT.

===

TG: it is a goddamn catastrophe sweeping the karkat population

TG: presidents on the headlines trying to get karkats everywhere to stop quarantining their asses and have a real heart to heart among themselves about the issue but they keep isolating anyways

CG: I STILL DON’T KNOW WHAT THE HELL A PRESIDENT IS. YOU’VE FAILED TO DESCRIBE IT AS ANYTHING MORE THAN A POORLY-SELECTED "DUDE CONDESCE" WHO DOES NOTHING PRODUCTIVE AND THEN EITHER DIES OR RUINS EVERYTHING, OR SOME CHAOTIC COMBINATION OF THE TWO.

TG: well that is exactly what it is but wait good point

===

TG: tragedy strikes as the karkat population reveals it doesnt generally know what a president even is so it means jack shit to them that this dude is trying to get their attention

TG: and mr president he is getting voted the fuck out of office over this blunder just an embarrassing display

TG: the public trust has plummeted off the fucking chart and cratered the damn ground like a meteor

TG: or he could be the tenth to die in office yknow there was a pretty big stretch of no in-office deaths til 2009 so maybe some catchup would be good for everyone

CG: ARE YOU TELLING ME YOU WANT TO MAKE ANOTHER PRESIDENT, AND THEN KILL HIM?

TG: not me personally i just wanna be there and see it also is that dream bubble fucking huge or what

TG: must be the size of

===

TG: jupiter

===

TG: look all im saying is the end of the world coincided pretty notably with a dry spell in the presidential kill:death ratio

TG: i was tragically too busy not dying to see obama die live on television when an errant meteor hit the white house that was my one chance

CG: PFFFT.

TG: i want to keep a comically aloof finger on the pulse of the shit but i do not want to be among the shit

TG: but anyways guess its my turn on the pedestal

CG: BE MY FUCKING GUEST.

===

TG: yknow uh im not gonna lie if present me went back to me age thirteen sippin my dubious aj in my pre-apocalyptic layer of hell that was texas and told me

TG: hey that gray text dude is probably gonna be your best friend if you give him a shot yall could be sweet bros in real life itll be awesome

TG: i mean disregarding the fact i already doomed that guy because i dont remember that happening to me

TG: id probably be casting some wicked aspersions on that shit

===

TG: our whole friendship feels like a plot twist to my damn life story

CG: I HEAR YOU.

TG: its like our narratives bumped into each other hard on the street and decided yknow what yeah this pavement is pretty cosy lets talk about your dad

TG: but

===

TG: dont get your think pans too wrapped up in that different timeline stuff

CG: IT’S THINK PAN. SINGULAR. NOBODY HAS MORE THAN ONE THINK PAN, EVER. IT IS A SINGULAR ORGAN. IF YOU WOULD LET ME READ A TROLL BIOLOGY BOOK TO YOU ONE TIME WE’D STOP BUMPING INTO THIS ISSUE.

TG: gotcha and no

CG: OBVIOUSLY.

TG: but anyways dude look

===

TG: i am literally a time dude and i can tell you right now with all the sage wisdome of my knightitudes

TG: not a good way of looking at it

TG: ive met daves that didnt like you either it doesnt affect jack or shit because those daves arent me

TG: like they are in a way but

TG: me and all those other guys spent the whole game honing down these doomed timelines to a fine point and that point has obviously involved a whole lot of hanging out with you

CG: …

===

TG: so

TG: maybe they just missed the point while you and me were on the breaking edge of that shit

TG: we got to the bottom line of it so it doesnt matter yknow

CG: HUH.

===

TG: and i mean plus

===

TG: ive seen a handful of alternate daves and karkats who get along uh great apparently so

TG: yknow

===

CG: WHAT?

TG: you know what i fucking mean im not saying it

CG: ROLLING YOUR SHOULDERS AND SAYING "yknow" GENERALLY DOESN’T CONVEY FUCKING ANYTHING MEANINGFUL IN A CONVERSATION, DAVE.

CG: I’M NOT A PSYCHIC. YOU’RE GOING TO HAVE TO TELL ME WHAT YOU MEAN. IN CANDID DETAIL.

TG: its besides the point anyways

===

TG: the point is its you right here that matters overall and you right here is chilling with me so thats gotta mean at least one or two things

CG: OKAY, OKAY, YEAH… I GET WHAT YOU’RE SAYING. I REALLY DIDN’T THINK ABOUT IT LIKE THAT.

CG: YOU HAVE TO UNDERSTAND BY NOW HOW IT’D BE REALLY FUCKING DIFFICULT FOR ME TO WRAP MY THINK PAN AROUND THE CONCEPT OF ME BEING THE RIGHT VERSION OF ANYTHING.

CG: BUT I FEEL LIKE THE AMOUNT OF TIME WE'VE SPENT TOGETHER CUMULATIVELY IN THIS TIMELINE MAKES UP FOR THE AMOUNT OF DAVES AND KARKATS WHO NEVER SPENT ANY AT ALL, BY AT LEAST TENFOLD.

===

TG: heh yeah

HAHAH.

===

CG: GOD. WHO WOULD’VE GUESSED THAT KARKAT VANTAS WOULD GET TOO FAR INTO HIS OWN THINK PAN ABOUT THIS BULLSHIT, RIGHT?

TG: stop repeating the words think and pan i get it already

CG: ARE YOU SURE? TOTALLY SURE? ABSOLUTELY ASSFUCK CERTAIN OF YOURSELF?

TG: yes dude

CG: ALRIGHT. KEEP IN MIND THIS WILL BE ON THE TEST LATER.

TG: im acing that shit i swear to god youre gonna eat your damn foot

CG: STRUT POD

TG: when i pass that shit to oblivion

TG: youre gonna regret doubting me

CG: OKAY, DAVE. THEN EXPLAIN TO ME WITH ALL YOUR SAGE WISDOME: WHAT IS A "LUMPSQUIRT"? AND REALLY, TAKE YOUR TIME THINKING ABOUT THIS. GOD KNOWS WE'VE GOT MOMENTS A-FUCKING-PLENTY TO SPARE.

TG: as the literal god of time in your local area i sure as hell do

CG: GO ON THEN.

===

TG: …

TG: pass

CG: EXACTLY.

CG: ANYWAYS, I’M STILL GOING TO GO AROUND FEELING ANOTHER LAYER OF PITY FOR THOSE GRAY BULGEMUNCHERS THAT DON’T GET TO BE FRIENDS WITH YOU. NOT THAT ANYTHING ANY KARKAT COULD FUCKING DO WOULD EVER MAKE THEM DESERVING OF IT, BUT THAT’S ANOTHER CAN OF DIRT NOODLES ENTIRELY.

TG: yeah i feel bad for anyone who isnt buddy-buddy with the david stri too

CG: OF COURSE YOU DO. I’M GLAD WE’RE ON THE SAME PAGE HERE.

===

TG: but also

TG: any dave who missed out on a slice of the realest homes in paradox space is a tragedy in my eyes

CG: Y--

TG: let me finish

TG: i just dont let it get to me so much cus… first of all ive been having to not let time shit get to me this whole damn game but also

TG: i know i have you here and thats whats important

TG: ok not "have" just
