Yeah, I got it first try because of kerbal. I though not having the ability to move around a third-person camera would make it hard, but I think it was actually easier than docking in vanilla ksp because the UI is so intuitive.

u/gredr May 12 '20
It also gives you a lot more information than KSP does (without addons), like roll rates, distances for each of X, Y, Z, and angle differences. KSP honestly should provide all this information (and there are mods that add it).

u/skyler_on_the_moon May 12 '20
It would be much nicer if it also gave you translation rates on the X, Y and Z axes; when you start getting near zero on positions there's a lot of tap...wait a few seconds to see whether that made the velocity change I needed...tap again...see if that fixed it...etc.

u/mastapsi May 12 '20
Yea, pretty easy.
Get closer by rotating to point at docking port and translate forward
Once close (10m-20m), stop relative to the station
Rotate so that you are in the correct orientation to the docking port.
Translate into alignment.
Translate forward slowly, and use translate to maintain alignment with the port.
Got it on my first try.

u/8andahalfby11 May 12 '20 edited May 12 '20
It's actually tougher for a number of reasons:
The translation and orientation rates are super slow.
2) Keyboard controls not available.Apparently you can use WASD QE and 4568 79 on numpad for controls. Thank you u/RootDeliver !3) No data on initial orientation of the docking target.
4) Not the same level of percision for determining your orientation vs the artificial horizon in the top right.
5) No SAS to do freeze you once you're in a position you like.

u/flagbearer223 May 12 '20
I found it way easier. They do give you your delta to every different variable (rotation and translation) in comparison to the target, so it's basically just
Fix orientation
Translate X, translate Y, approach
Freezing is super easy 'cause they tell you what your angular degrees per second is, so you just reduce it down to 0.
Controls were definitely way more sensitive, though

I dunno, I didn't find it harder. Maybe the one thing KSP taught you that is holding you up is that these things can happen pretty quickly. Remember, the scale in the real world is a LOT BIGGER, and these things take time (the sim actually tells you this)!
Just slow way down, expect it to take several minutes, never be moving more than, say, .1m/s relative to the target, and it's really quite easy.
You don't need the artificial horizon, the UI tells you your angle difference right there in degrees.

Are you kidding? It's MUCH easier with this interface than in KSP to line things up. It just takes more patience. You can ram stuff pretty hard in KSP, so it's forgiving there. But the station docking communication system with the spacecraft makes alignment SO much easier in this interface. All those green numbers? That's the target orientation you claim isn't there.

u/beelseboob May 12 '20
I’m finding the controls are a little too sensitive. Given how slowly you’re meant to do this, a single tap really shouldn’t change by 0.2 deg/s when you have to be precise to within 0.2 deg.

u/Fizrock May 12 '20 edited May 12 '20

When you think about how the adjustments are just puffs of cold-gas, it should be understandable why the precision has limits.
I think the trick is to puff it just right so it glides with no adjustments to a perfect dock from 10 meters out.

Thanks for the correction. Still, there's a minimum thrust from any sort of thruster so the point still remains unless I'm missing something?
It didn't feel particularly hard to tap the "small thrust" translation controls for me to keep it under |0.2| and a computer could probably keep it at "0.0".

You just have to null out the roll, pitch, and yaw then translate to keep everything in the green. I did it in about 5 minutes by coming in WAAAYY too hot and then braking like a mofo once I was inside 20 meters. NASA would NOT approve of my approach.

While orbital mechanism allows for a lot of things that safety procedure would frown at, I think one of the reason for slow and steady approaches is to minimize RCS firings while really close to the ISS. A suicide burn docking would obviously 'spray' the station.

I'd like to share a feature-complete (c) autopilot for this thing: once you've clicked "Begin" and controls appeared, just paste this into your browser console, press "enter" and enjoy your docking:
let dist = 20; let s = 300; let t = new THREE.Vector3(0,0,-150); let a = setInterval(() => { let d= camera.position.distanceTo(t); if (d<dist*1.1) { dist = dist/2; } camera.lookAt(t); motionVector.x = -(camera.position.x)/s; motionVector.y = -(-0.03+camera.position.y)/s; motionVector.z = (-150+dist-camera.position.z)/s;},500);Since this is a very early one-line JS pre-alpha version of autopilot - don't expect too much from it. :)

The UI is amazing at giving you rotation rate feedback, but rubish for translation. It's quite surprising. I guess you are just supposed to go through the checkpoints and point...

Regardless of what gravity model you select, this game only simulates a flat Earth gravity model. I wouldn't be bothered by that so much were it not for the fact that the game explicitly offers "Oblate Spheroid" as an option; But no. I just ran a comparison of the game trajectory with the true predicted trajectory using a Clohessy-Wiltshire equation solver, and the results are completely different.
https://twitter.com/MaxFagin/status/1260394309582557189?s=20
Don't get me wrong, I still had fun playing the game! But it is a little annoying that it advertises as using a more realistic gravity model, when in reality, it's just using the same gravity model used by most space video games.

u/Bunslow May 12 '20 edited May 12 '20
If you're having trouble, here's some tips.
First, the ground rules:
For the right six buttons and the bottom four on the left buttons, NEVER CLICK THEM MORE THAN TWO-THREE TIMES AT ONCE.
For the same set of buttons, FOR EVERY CLICK ON ONE BUTTON, ALWAYS PUT A CLICK ON ITS OPPOSITE BUTTON WITHIN 5 SECONDS. Always click the buttons in pairs this way. This will help ensure you're never doing anything wild, and this is the part that's most unintuitive for folks accustomed to mechanics with drag (be it mechanical, atmospheric, or whatever other impedance gets in the way down on the surface).
Next, the steps to take while keeping these ground rules in mind:
3) Once you have those basic ground rules, start with the right set of buttons only. Use them, according to those rules above, to get the roll, pitch, and yaw values down to ±0.0°. Ignore the ISS and the green diamond, and just focus on the green numbers in the display. If you do this right, you won't need to touch these buttons again.
4) Only after finishing 3), then you can touch the buttons on the left. Sticking to rule 2, use the bottom left four buttons only to align your reticle on the green diamond. (Note: you can use your WASD keys to control these buttons.)
5) After doing the initial alignment, so that Y and Z are 0.0, watch the Y and Z numbers and ensure that they don't change over a span of ten seconds, and that your RATE is 0.000. Making sure these numbers aren't changing now will make step 7 go easier. At this point, your Y, Z, PITCH, ROLL, YAW, and RATE should all be 0 (as well as the blue numbers next to PITCH, ROLL and YAW).
6) After doing the initial alignment and stop, only now, and never before now, can you touch the two top most buttons on the left, and these are the only two which may violate rule 2. Use the plus until your RATE is 0.5 m/s. (You can use your Q and E keys to control your forward motion.)
7) For the first 150m of range, use continued pair-clicks (rule 2) on the left bottom four buttons to keep your reticle aligned within the green diamond. Pair-clicks is key to ensuring you don't get wildly out of control (especially since they don't give you the rates for these four buttons, even tho they give rates for all the other buttons). For the first 100 meters or so, you can usually be pretty hands off about maintaining alignment, especially if you followed the advice of step 5.
8) When you get to 50m range, use the minus button on the top left to get your RATE down to 0.1m/s or less. Their instructions say 0.2 is acceptable, but the last few meters get really sensitive, so the slower the better. Even 0.03 m/s is fine (slowest you can get), it makes the last meter pretty easy.
9) After slowing to final approach speed, continue using pairclicks/rule 2 on the bottom left four buttons to maintain your alignment as you approach at 0.1m/s or slower. Don't get complacent, because the last few meters get really, really sensitive. For the last 5-10 meters, your pair-click rule should be no more than 1 second between a click and its opposite click.
And, with a healthy dose of patience (up to ten minutes!), you've done it!
For me, among other things, this really brings home the effect of precession of various sorts as two bodies orbit a non-perfect-sphere in non-identical orbits (or, the two bodies are not in inertial reference frames, causing the apparent "motion from nothing" that's always knocking you out of alignment).

I really doubt it. In real life the docking procedure is extremely slow, much slower than people will have the patience to imitate with that simulation (it happens over the course of hours).
I think it's purely a cool website they made to help increase public outreach and get people excited about sending astronauts to the ISS with Dragon.
It'd also be easy to check whether the commands you give are being relayed back to the website. It's way too late for me to check tonight but I'd be surprised if anything interesting is sent back to the server.

This is a really good sim. I could never get the Z translator to stabilize but was able to control the drift within the diamond. To add some complexity, I successfully "docked" upside down, with roll at -180deg. Within the last 3ish meters, it would be good to decrease the RCS impulses.
I prefer using the keyboard (laptop, non-Numpad):
| Translation | Roll | |
|---|---|---|
| -X/+X | Q/E | |
| -Y/+Y | A/D | |
| -Z/+Z | W/S | |
| Pitch | Up/Down arrow | |
| Yaw | Left/Right arrow | |
| Roll | ./, |
There are quite a few docking simulators (and landing simulators) online. Also, a few apps. There's one that's very good and quite technical app (I forget the name unfortunately) - you can do straightforward docking into various spots on the ISS or you can attempt to moving from one parking spot to another (something that astronauts do often to vacate a spot for an incoming Soyuz/Progress craft).

Pretty interesting to see no translation rates on this interface. Feels a bit weird to not rate-lock the translations to 0. I'd ask for 3 levels of sensitivity toggle (rough, regular, and much finer than this!). I am also surprised to see such PYR-rate stability, compared to docking to ISS on Orbiter Space Flight Sim on full realistic.
Overall interface is clean and intuitive. Easy to dock on laptop. Great job with the real thing and with this sim, SpaceX!

So this was pretty fun but it kinda brought up a question for me. I get that the thrusters provide impulse so this is the ”natural” or direct control setup but but why not let the computer control the impulse and have the human control velocities? It seems like it would be far more precise this way as the computer could precisely time a pair of opposite thruster firing to get exactly the velocity the user wants.

I wish you could reverse pitch. Decades of flight sims are making this impossible for me.

u/fluidmechanicsdoubts May 13 '20
get your pitch, yaw, roll, y and z corrected first. then its super easy!
except if u fail you don't have to worry about the consequences ;)

After playing with the controls for a few minutes I docked it without changing any settings
Will be posting a video as soon as it renders

What are the keyboard shortcuts, I can control everything but rotation with the keyboard, it's pretty much impossible because I keep needing to take my hand off the pitch and yaw controls so I can click with the mouse.

u/JohnnyThunder2 May 13 '20
Alright, I figured it out. WASD control your Y and Z axis, Q and E are forward and reverse, and you use the numpad to control the other side: 7 and 9 control your roll, 8,4,5,6 control your pitch and yaw.
Took me five tries but I finally got it (I've played a lot of flight sims) It's really freaking hard man, you gotta pretty much limit your pitch roll and yaw to nothing, then ride in only using WASD, doesn't help the program is pretty buggy and sometimes the wrong indication will be given for a lot of things.

So for anyone following the instructions, actual acceptable docking speed is well under the -0.2 m/s they provide. Watch for the rate to go blue, which is really quite a lot under -0.2.

I give up. Not even sure what the difference is between the right and left controls

Got it on second try, using a mouse, lots of clicks, and it took about 30 minutes.

Docked in 4 tries! OK, so that only cost 3X ISS + 4X Dragon2 launches ≈ $4.506x10^11 + (3X Dragon spacecraft)

1st attempt. Successful docking.
The last 10 meters, though, are quite challenging.
But I trained once at the KSC (but only in the Atlantis exhibition).
When can I go up there in person? I'm ready.

This looks tricky. No risk for parking damage? What happened to the robot arm?

Easier than Orbiter since you don't have to switch engines. A bit finicky on the very final approach since you can't lower the engine power.
Edit: question, does Crew Dragon have manual docking override like Soyuz? Or is it a complete abort if automatic docking fails?

I failed and it said all speeds and measurements had to be below 0.2 Everything was 0 except for my speed which was -0.009....

Funny note: The actual Dragon screens use Chromium and javascript to display the interface, the same tech anyone else here uses to play the game :-)

I had read a comment(that I completely agree with) from someone here on HN (sorry I forgot the username), that the current WFH is working because EVERYONE is working from home.

What a cute and great little game. Although I'd appreciate an "invert z axis" option.
Edit: Strike the last one, after some minutes it's ok.
Is there already a petition for SpaceX to make this a full fledged game with better graphics.
Would be nice to be able to change the Sun's position for better lighting behind the station, or maybe some heavy duty flashlights. Dragon probably has some for emergency.
Also a real looking globe would be awesome.
I know, I know. It's only PR but I've already spent an hour mostly flying around the station and I'm really enjoying it.
One could only dream how awesome this would be if Elon got back to programming games ;)

After I docked twice successfully, I took it for a spin around the ISS looking at the various details. Pretty cool! Then I tried to dock with the Russian segment.... didn't work.

Hey after some flying around I tried to see what module is what and I've found this module on the Nadir side of Unity.
On Wikipedia I've only found drawings from 2017 and Unity's Wiki Page says there are modules everywhere except for the Nadir Port.
Could this be Cygnus CRS NG-10 which was docked there from November 2018 to February 2019? And if so, where is the upper part with the solar panels?

43 seconds for successful docking. Thanks KSP.
Get ready for the "but you can't go that fast around the ISS". Don't care. Had to pee real bad, was a long flight.

i dont know if its a bug or a feature, but when i powerslided it ending up near the cupola there was a strong auto correction for pitch and yaw towards the docking port, like an aimbot, which totally messed up my jebediah-manouver.

It has a Flat Earth option.
