That Moment When...

[CatastrophicFailure]

That moment when you send out an interplanetary probe, go do something else for a while, then return to it for what was supposed to be a tiny correction burn, only now thanks to rounding errors, it's half your remaining delta v.

[mythic_fci]

Bumped!

That moment when you burn for Eeloo, come back after 20 minutes, and find out your burn was miscalculated.

Landing a manned outpost on Eve to notice when a Kerbal exits you forgot a ladder.

Repeat the exact same thing on Laythe..

I sent a KAS-box full of ladders to fix that

[Red Iron Crown]

Landing a manned outpost on Eve to notice when a Kerbal exits you forgot a ladder.

Ugh. I did something similar. Made a good Eve lander, even had ladders. The kerbal couldn't crest the top of the tank to reboard the ship. Why won't you scramble, Jeb?

I hacked gravity to get him back in.

[mythic_fci]

And... Bumped yet again.

[John FX]

The moment you install a new mod which borks your game and then when you remove it your game is still borked and KSP won`t load meaning you have to reinstall ALL of your mods onto a fresh extract of KSP...

[ibeinsane]

When you undock your lander craft and then switch back to your orbital craft to go to a higher altitude with your last remaining fuel to become your permanent comms sat only to discover half way through the burn the control module is backwards and you have just deorbited your comms sat with no fuel left. (Made worse with remotetech as now both crafts are doomed)

[Herr Doktor Strangemember]

Just add my $0.02, when using KSPI with the KASA-IXS mod the direction you place your drive rings matters...moving across the system at lightspeed in reverse is a scary moment when you check your map. Although Jeb seemed to enjoy it.

Regards.

[Pikachu8091]

That moment when you time warp really fast to hurry up and get to the Mun, and you hold it a second too long, and by the time has slowed down, Jebediah's funeral is just finishing.

[StrandedonEarth]

... you belly-land your not-meant-to-land science station on Gilly with a single vernor to do a "science from..." contract and rediscover what you had forgotten about this station: It has no antennas!

[General Rarity]

That moment when your rover decides to decouple from your lander when you ignite your first stage.

[SkyHook]

The Science lab eats all 1200 of your science..

[Nedal]

That moment you realize you've just placed 50 struts without symmetry enabled after reverting a test flight of a huge huge launcher.

[Duke23]

That moment when you undock from the transfer ship for an unplanned Ike visit, start to deorbit, and realize you didn't refill the tanks.

[StrandedonEarth]

That moment when you undock from the transfer ship for an unplanned Ike visit, start to deorbit, and realize you didn't refill the tanks.

Or that's when you realize the transfer stage was sucking fuel out of your lander through the clamp-o-tron.

[Frank_G]

That moment when...

you say "No KSP today" and later find your desk full of sketches with craft designs for upcoming missions...

[Samniss Arandeen]

That moment when...

you say "No KSP today" and later find your desk full of sketches with craft designs for upcoming missions...

You and I both, brother.

That moment when you have DRE and FAR installed, and still you try to aerocapture on your Duna mission.

[Xacktar]

...you connect all your space base parts together, only to realize the connections block the crew module exit hatch.

[corvustech]

...you get that all-important money-printing science-gathering satellite into space, only to realize you forgot the solar panels.

...the white noise from a long burn late at night makes you fall asleep...so you wake up in deep, deep space with no fuel.

...you shrink down the text size of your browser to an almost unreadable scale just so your co-workers don't see you're posting on KSP forums

...you launch a solar orbit probe and discover only after you circularize that you forgot antennae.

[brdavis]

That moment when… the three liquid-fueled strap-ons that were all built with symmetry on do not burn out a the same time, resulting in just one burning long and the entire stack pinwheeling around much faster than the reaction wheels can do anything, and you have to try to regain control via manual control, after also striking the cast-off strap-ons that staged while you were spinning at about 0.5 revolutions per second…

Yeah, it was an interesting day.

[SlimeCrusher]

That moment when you spend all day designing a launcher that you can use... And when launching you notice it bends on the middle... And the whole thing explodes...

That happened to me today, trying to build a Saturn V-like launcher

[KevinW42]

That moment when your asparagus-staged rocked keeps flipping over for seemingly no reason, only for you to discover that you forgot to turn symmetry back on when repositioning one of the boosters.

[djnattyd]

That moment when your old manager says he flat-out believes the moon landings were faked and you sit there thinking "well, I guess you don't have to be smart to be a leader of people" whilst resisting the urge to go all Buzz Aldrin on him.

I know, I know, its not strictly KSP related but still... This is why aliens will never visit us.

[Wiseman]

That moment when you realize inflatable heat-shields aren't terribly heavy, and your Eve lander probe flips science package-first into a 6000 m/s aerobrake.

[SubzeroSpartan7]

That moment when you're halfway back from Dres and you realize you forgot parachutes.
