Microscopic Rockets

[spikeyhat09]

thanks the the increased power of the (relatively) new rockomax engine over the ant, some teeny tiny endevours are possible.

Id like to see some other "small scale" operations! post em!

Tiniest asparagus I've ever seen. And that music.... what the...

[bogpad]

well, this propably is the first video I have ever seen where I thought the nyancat son fits!

sadly, I have no experience with taking videos, so I can't really add to this, but I indeed planned on a microscopig space station. If the thread is still alive, I may post a pic when it's done.

THAT MUSIC ... Nyan ftw!

Can you do even smaller than that?

[AncientAstronaut]

Sloppiest insertion burn ever. You know you can pitch down under the horizon to bring your Apokee closer to you and then pitch back to horizon level for the moment of insertion?

[Superfluous J]

That's pretty awesome. Reminds me of a set of Mini Munar Landers I tried to make, using those tiny boosters (that you're supposed to use to get huge rockets to fall away from your next stage) to fire retrograde and kill as much orbital momentum as possible. Sadly, the only time they fire perfectly straight and don't have any roll at all is when you launch from a perfectly still base. AKA the surface of a planet aimed straight up.

I gave up on that idea, but it's nice to see someone was able to use the same trick for good

Start turning at 200m. You should be at 45º inclination when you reach 10 Km.

[Sma]

Ahah....the music makes this even better.

[Giggleplex777]

I made a Scout that can send a small probe to a 80km by 800km (probably more) orbit with 20 degree inclination.

[draeath]

His insertion technique was not the question, he was showing off the tiny spacecraft :/

[Giggleplex777]

Has anyone here ever done a legit gravity turn?

[Guest Aaack]

Loved the video and the nyan music! it's been a while lol

Ok now you've inspired me to send the tiniest probe to duna (my first mission to duna yay)

[Giggleplex777]

I like small rockets too. Here's my latest Duna rover:

I'll make an album soon.

What does that even mean?

What does that even mean?

Instead of constantly manually turning your rocket while flying to orbit, you move the rocket a little after flying straight up, and gravity turns the rocket by itself.

I did it once, but I throttled too high and got a bad trajectory.

[Comrade Jenkens]

I have never been nyaned for so long

[Tw1]

It makes good retro rockets too. Well, its KSPX incarnation did, there are a few more parts that I need to get working before I can update my starfighter.

[MalfunctionM1Ke]

That Video is awesome. But Nyancat... i dont know, at least it fits the size of your Probe

And dont mind about anyone complaining about your gravity turn or deceleration.

As Long as your rocket hits the ground in the end, everything is fine

Its not the most efficient way with the current drag model.

You should burn straight up until at least 10km, then begin the turn reaching 45 degrees by 20km for normal sized rockets. The rest of the turn depends on the desired altitude and the strength of the current stage.

It's not very efficient, but it the real gravity turn (not the controlled turn that most people incorrectly call gravity turn). There's also very low drag loss loss.

[Bunsen]

Yeah. It's a pain in the ass to start it right, and the standard KSP aerodynamics make it not work all that well unless you're headed to a high orbit. It's much more useful if you're running FAR, where you don't have to be quite so scared of reaching high speeds at low altitudes.

The most efficient way is to start turning at 200m slowly. You should be at 45 degrees when you reach 10Km. You should keep within 10% of the velocity vector till your T is more than 1 minute long, then you can go directly to the prograde vector.

[spikeyhat09]

erm, if im not mistaken with the current aerodynamic model in the game, the way i did the gravity turn is about as efficient as it gets (for minimal thinking)

it doesn't have to be a vid, i was really shooting for pics

The problem with turning immediately 45 degrees at 10 km is that you waste more fuel circularizing the orbit, since you have a high and narrow apoapsis.

I'll admit, I normally DO put more thought and care into my curves, but in this situation i just wanted to get it done because i had things to do (going to a wedding)
