Collisions

[Dedjal]

Only had one. I had managed to get the maincore for my station up into orbit and put the leftover fueltanks and rockets on a deorbit path. I then proceeded to launch a module of habitats etc. During my ascend stage, I could see a fireball coming in my direction, ramming the mainsail on one of my outter fueltank and tearing it off. I quickly separated the fueltanks and managed to get it to orbit. The stage I had to drop was just about empty anyway.

[rodion]

Had my first actual accidental collision between two separate craft today. Also the only docking I've ever ruined after the fact (no, I didn't quicksave either). I guess 20 or 30m at an angle isn't enough clearance to start retrofire when you have NERVAs and solar panels, among other things, sticking out on those extra-long struts.

[Rage097]

I either

A.) knock off solarpanels with a Kerbal

B.) As above but during docking and with a ship.

C.) Collide with That little son of a... Ike

D.)Have a DEC, or Dres Existential Crisis.

[Scorpi15]

My friend collided with something in orbit. He set Mechjeb to rendezvous with the moon at ~100m separation. Needless to say, MechJeb did it's job perfectly.

[superm18]

I came close today, twice.

[Prome]

managed to hit the mun, does that count?

[Kodiak42]

I was trying to dock with another space craft in orbit of Kerbol... And I had my direction right on the money, unfortunately, I was going a bit fast. I saw the distance continue to drop, I still couldn't see it very well, and then *BOOM* Both were in pieces... Why must I be so accurate?

[lordlundar]

Yeah I have.

My first operation on a new save is a satellite in a 80-100k circular equatorial orbit. My usual procedure is a three stage rocket, a launch stage, an orbital stage, and a circulation stage. The launch stage wet beautifully, the orbital stage put it rather oblong but otherwise smoothly. I had waited till I was close to periapsis and ejected the orbital stage. I then set up to lower the apoapsis to a circular orbit. This set up required going retrograde.

Perfect retrograde.

Did I forget to mention that when I ejected the orbit stage i was at perfect prograde?

So I fired up the engine and whoops! You know the martial arts "one inch punch?" This was essentially the orbital space equivalent.

Lesson learned, point the ejection part AWAY from where you will fire to (preferably straight down to the planet), THEN eject!

[Moon Goddess]

I hit no, because while I've collided hundreds of times in docking maneuvers I don't think that's what you're asking.

I have never hit anything in orbit that I wasn't purposefully trying to get close to.

[LtHeckard]

There is a rock orbiting above Ike, and if you get too close it will blow your spacecraft up.

[fatfluffycat]

This is the closest I ever got to space debris

I got a orbit right under it

[Captain Sierra]

What mod those engines??

Also, I succeeded in repairing a solar panel today that was taken off from a collision with a single use tug, so now my station looks balanced.

[fatfluffycat]

What mod those engines??

Everything you see in the 2 pictures are from Bobcat soviet pack, basically it adds a lot of real life Russian rockets.

[Wait- Was That Important?]

I've had only two encounters with debris.

The first was a strut end, which fell off because of that weird glitch where putting them attached to bicouplers makes the ends decouple and float around, which came within a paltry 5.6km.

The other was the entire second stage of one of my KW launch vehicles, which I had jettisoned immediately after using it to get a close intercept with a station. A few orbits later the entire thing, which is like 10 meters tall and weighs 17 tons dry, smacked right into the middle of my station at about 75m/s closing speed. No more station after that

The bottom part of this rocket is the second stage. It's in 3.75m diameter, so it's fairly large on its own.

[lajoswinkler]

I have to report this, it's crazy. I've experienced a collision during early stages of rendezvous in Duna orbit after a successful manned landing mission. This never happened to me away from Kerbin.

This is the lander I used.

It didn't have enough fuel to reach orbit, so I've established a stable orbit using RCS. Barely.

The tug ship was in a much higher orbit so I've lowered it down to catch the lander. This wasn't during the RCS phase. The lander simply turned from a point in the distance to a large explosion, smashing into the tug, ending in a roughly same orbit after this energy transfer.

It happened so fast, I've almost forgot to take a screenshot.

Surprisingly, the only damage was to the lander itself. One busted bipropellant and one RCS round tank.

I've managed to return Bob and Bill to Kerbin, making this my first manned mission to Duna and back.

They almost crashed into Kerbin because one of the parachutes had a problem. They almost died few times during this mission.

[The Destroyer]

Well, its not like a debris field collapse, so I voted no, but I have on occasion decoupled, turned around, burned, and bumped into a stage

[Spyritdragon]

No, but i have blown my target away with my target retrograde exhaust.

[Fendleton]

I've had both high and low energy collisions. One of the more spectacular was when a piece of on-rails-for-ages debris from a failed mission to the outer solar system managed to plow through the middle of a space station, with predictable results.

[Unistrut]

When I was first trying to dock I slammed into my target at 30 m/s. Haven't had any random orbital collisions though, despite every mission afterwards having to fly out through the equatorial debris belt left by that collision.

EDIT:

And I have at least once, undocked, lined up with a target on the nav ball and then floored it straight into the thing I just undocked from.

[dr_jt]

I had a perfect encounter with my station and ended up within 200 meters of it. I started thrusting towards the station and then decided to decouple my last stage and continue using just RCS. Just as I was about to dock I saw the stage coming towards the station. I aborted the docking and tried to get to it and bump it out of the way before it hit the station but I didn't make it. It took out half the station. I was lucky that no Kerbals were in the wrecked sections and I was able to rescue them. Another time during launch I ran into an orange tank that was left in a lower orbit. I've also knocked off panels while approaching for docking and took out a couple of panels with Kerbals doing EVA. One time the panel was just sitting there a few meters away and I wished I could have grabbed it with the Kerbal and reattached it.

[Adslegend]

On one of my first docking attempts I misjudged how long it would take to slow down so I hit the station. Luckily it only caused a small amount of damage.

[3_bit]

I've never really hit anything in orbit. But technically speaking, I have when I tried to (back in the old days) have Bill go out on EVA and deorbit a large fuel tank and a mainsail. No luck, obviously.

[Ferrit]

Not hit anything in orbit (excluding docking errors) but did have a piece of debris in an elliptic come very, very close (<<200m) at very high relative speed while assembling my space station. That brought back the risks and prompted a clean up of near Kerbin orbits. Now take even more care to avoid leaving spent stages flating around, and any debris that misfortune leaves in orbit is a high priority to be hunted down and de-orbited.

[Godot]

Nope, I had close encounters with orbiting debris, but never hit anything (in the latest versions of KSP I always ensure that spent stages either get decoupled at altitudes that let them fall back to Kerbin, or at orbits that don´t endanger anything that is in orbit (or pollute the orbit I frequently use as staging point for my spacecraft ... which is around 100-125 km)).

Don´t want to have any scenarios like the one in gravity happen

[madbadger2742]

When I was learning to dock, I got this really nice .1km intercept from launch. But during my circularization burn, I lost all controls and the navball spazzed out. I switched out of map view to see nothing left of either ship but a huge cloud of debris. It turns out that 1 km/s docking doesn't work so well.

I've had more orbital collisions than I care to remember, but that one really stands above the rest.
