measure temperatures


Recommended Posts

Hi everyone, I'm new here on the forum, I bought Kerbal SP and the dlc´s for some time but only in the last few days I started to pay more attention to the game, I find the game very difficult but I´m trying to learn so I´m here to let a doubt I have I love the game I find it addictive.
I'm playing in career mode and I'm on a mission that I can't complete, the mission is to measure temperatures in flight below 17,700 meters near the P-PS sector.
I don't have all the parts to build a plane, will it be possible to complete this mission with a rocket?
If so what parts do you recommend to build the rocket.
I do not know how to speak English and I translated this message on google translator I hope you understand my doubt, thanks.

Yes, you can use a rocket. You will see two notifications on-screen:
- "You are entering Sector P-PS" and
- "You are leaving Sector P-PS"

You must record the temperature in between these two events and you can be at any altitude below 17,700m. With a rocket you will be travelling reasonably quickly so have the thermometer window open, ready to click the button. Any rocket that you build that can reach that zone will be suitable. If at first you don't succeed you can always revert to launch and try again.

And, welcome to the forums!

These 'below a certain km' have become my bread and butter income generator. As you seem to be in early career (haven't unlocked the Aviation parts), then I imagine the target site is fairly close to the KSC, so is reachable by rocket.

A few tips:

  • Just before you launch, go to the Map screen, click on the target area (it will be a little thermometer icon) and select 'Activate Navigation' - this will place it on your navball, which makes aiming in the right direction easier.
  • Go slow with a small craft: A command pod with a thermometer attached to the side, a fuel tank and a swivel engine, with some basic fins. Lift off slowly, get pointed in the right direction, and try and keep your speed down to limit the aerodynamic forces causing your craft to flip out.
  • As you enter the target area, you'll get a message on screen. Be ready to quickly run a temperature reading.
  • Bring a parachute!

Thank you very much, I will test to see if I can, I think so.  :)

 

I've already completed 5 missions but now I have another mission that I can't complete because I don't understand, I've done several tests and I'm not understanding the mission well, the mission is:

Test swivel fuel engine LV-T 45 in a sub-orbital path over kerbin and I have to reach a height between 150,000 to 160,000

well, I know how to fly in sub-orbital and I managed to get to that height that is necessary for the mission, I installed this engine in my rocket, I completed all the tasks in that mission but when the rocket reaches the maximum height and starts to descend when down the 150,000 meters a part of the mission is disabled because the test must be done between 150,000 and 160,000, I don't understand this mission, I even installed two swivel LV-T 45 engines, one to take the rocket up to 150,000 and then use the second engine at that time, but the mission is still not complete, does anyone know how to do this mission?

For Test missions, you must right click on the part (the LV-T 45 Swivel engine) and click on 'Run Test' when the requirements have been met. So get between 150,000 and 160,000, then right click on the part click 'Run Test'.

So you're doing everything right, but you need to manually run the test.

Alternatively, you can activate the part as part of the staging sequence - you mention you've tried doing this with a second Swivel engine, and it's not completed the contract which is certainly odd. Have all the requirements been met - all green ticks on the contract?

... your tips were very important to be able to finish these contracts after making some equal contracts this is now easy for me the most difficult right now, I have to orbit kerbin and travel to Mun and I can't, the videos that exist on youtube they are in english a language that i cannot understand very well, i searched but i cannot find a video or a tutorial (written) in the language i understand, the ideal for me would be a tutorial or "written" tips to later select this tutorial and translate it on google translator, the videos are already more difficult to understand because it is spoken and not "written", I will continue to research but I do not have high hopes of finding what I want, any way, thank you very much for the tips you guys gave me were very important. :)

@TiaguX84

Hopefully this will help:

Guide to Orbit

To achieve orbit requires two things:

  • Going high enough to escape the atmosphere
  • Going fast enough sideways to counter Kerbin's gravity

If these two things are done at the same time, you will enter orbit.

Going high enough

Kerbin's atmosphere ends at 70,000m. After this, you're in space. On Earth, this is called the Karman Line. 

To orbit, you need to be above this height, otherwise, the atmosphere will slow you down, and gravity will pull you back into the planet.

Going fast enough sideways

Once you're above 70,000m, you need to go sideways fast enough (about 2,300m/s), so that as gravity pulls you back towards the planet, you are falling 'around' the curve - as shown in this diagram:

Satellite-speed-and-force-directions.jpg?1522293429

How do we do that?

To go high enough, and fast enough sideways, you could go straight up to 70,000m, then turn sideways and burn until you go fast enough - but that is very inefficient.

Instead, we want to balance going up, with going sideways. 

But it's a little more complicated than that. Because at sea level (ASL), the air is very thick. If we try and go sideways too quickly, our spaceship will meet a lot of air resistance, which we will spend a lot of fuel overcoming, or the aerodynamic forces will be too strong, and our spaceship could become uncontrollable - or break apart completely.

So instead, we take a path that looks like this:

Do our rockets go up straight? They seem to curve when observed ...

As you can see, we takeoff vertically, escaping the thickest part of the atmosphere as quickly as we can, and then gradually pitch over until we're out of the atmosphere. 

That's the theory. Let's build a ship!

A ship that is capable of orbit can be quite simple. It needs to have a powerful 'lifting' stage, that can get the rocket out of the atmosphere quickly with a lot of thrust. And a more efficient second stage, that doesn't need as much thrust - but is more suited to operating in the vacuum of space.

Let's start at the top. You'll need:

  • Mk16 Parachute
  • Mk1 Command Pod
  • Heat Shield 1.25m
  • TD-12 Decoupler
  • FL-T200 Fuel Tank
  • LV-909 "Terrier" engine

That's your upper stage. This will be the 'orbiter' section of your ship, that once we've got it into space, will complete the 'circularisation burn' that will get us into orbit. 

And to get it up there, we'll need:

  • TD-12 Decoupler
  • 800 units of liquid fuel (either 1x FL-T800 tank, or 2x FL-T400 tanks)
  • LV-T30 "Swivel" engine
  • 3 Basic Fins

While this is pretty powerful, it could do with a 'kick-start'. So lets add a Solid Rocket Booster (SRB) underneath the stack. SRBs have a very high thrust-to-weight ratio, so are a great way to get your rocket moving in the thick atmosphere:

  • TD-12 Decoupler
  • RT-10 "Hammer"

Make sure you correctly set up your staging, so that when you 'stage', it decouples the previous stage, and lights the next one.

The mission

The general flight plan is as follows:

  • Turn on SAS, and activate the SRB, which will propel us upwards. 
  • At 100 m/s, pitch to 10 degrees to the East (right) with the D key
  • Drop the SRB when it runs out of fuel, and light the 'Swivel' stage 
  • Slowly pitch over to 45 degrees by the time we've reached 10,000m
  • Maintain 45 degrees until we reach 20,000m, and pitch over to 30 degrees.
  • Go onto the map screen, with the 'M' key, and look down on Kerbin's north pole to see your trajectory.
  • Push Apoapsis above 70,000m
  • When out of fuel, press X to cut the throttle, and then drop the 'Swivel' stage.
  • Mouse over the Ap symbol, and at 25 seconds until Apoapsis, point prograde and light upper 'Terrier' stage.
  • Keep burning until you push your Periapsis above 70,000m
  • Celebrate!

If you need some screenshots of this in practise, let me know!

that link has the image of the option I'm talking about, in option 3
sorry I was unable to add the image in the post, I tried several ways and it doesn't work, so I left the link.

I don't understand what the RCS option is, what does it do?
it's the only thing I don't know about navball.

If you have any of the following parts on your craft:

https://wiki.kerbalspaceprogram.com/wiki/RV-105_RCS_Thruster_Block

https://wiki.kerbalspaceprogram.com/wiki/Place-Anywhere_7_Linear_RCS_Port

https://wiki.kerbalspaceprogram.com/wiki/Vernor_Engine

RCS will activate them.  WASDQE, IJKLHN, and SAS control them.

That's the indicator for your Reaction Control System, or RCS. If the indicator is green, it means you have activated your RCS; pressing the "R" key on your keyboard toggles it on or off.

It doesn't matter whether your vessel actually has RCS thrusters and/or fuel, so it may be misleading at times.

Hi
I have a contract to take 5 passengers in sub-orbit but I'm not getting it.
I have 3 modules to carry a maximum of 6 passengers I built a rocket but it takes a long time to get off the ground because it is too heavy, I tried to add more rockets but it exceeds 30 pieces and now I ran out of ideas, what do you guys recommend?

Launch a smaller rocket with only one or two tourists in it. If you have any probe cores unlocked you should stick one on the front of the pod so you can put a tourist in there instead of a pilot. It will take more launches to do it that way but it’s still cheaper than upgrading the VAB and launchpad. Remember parachutes!

Hi again TiaguX84. 

As an early contract, this looks like quite a tough one, especially with low level technology. But that doesn't mean we can't do it!

If you can afford to upgrade your VAB (right click on it, then click 'Upgrade'), then that will give you more parts to use. But I don't think we need more than 30 parts here.

You need to think about keeping your rocket organised into two stages: 

  • The passenger module. This needs to carry 5 Kerbals - and bring them back safely from over 70,000m
  • The lifting stage. This needs to be powerful enough to lift the passenger module, and efficient enough to carry it on a nice suborbital trajectory.

Lets start with the passenger module. 

You'll need some sort of command pod. Let's use the Mk1 Command Pod, because I know you have it unlocked. That has space for one Kerbal - so your first tourist can sit there.

But what about the pilot? Well, hopefully by now you've unlocked a probe core - specifically, the Probodobodyne OKTO, which can be unlocked under the 'Electronics' research node. This lets you fly a rocket without a pilot on board; and this particular probe core also has SAS capability, which is important!

The OKTO is tiny, so can fit right on top of your Mk1 Command Pod - and a parachute can fit right on top of that! 

Now we need to think about the rest of the tourists. Fortunately, there's a handy Crew Cabin - it's called the Mk1 Crew Cabin, and it's unlocked early on in 'General Construction' - so you might already have it. It fits two Kerbals, so place two underneath your Mk1 Command Pod - and there you go! A 5 Kerbal Passenger Module, with remote control, and a parachute! 

But it might be worth adding a couple of extra parachutes - just to make sure your Kerbals land nice and safely; they're paying a lot for this trip!

Example:

Spoiler

Onto the lifting stage!

Now we need to think about getting it onto a sub-orbital flight. We could just strap some Solid Rocket Boosters to it and watch it fly; but if you launch too steeply, your rocket might not have enough air to fall through to slow it down on the way back down for your parachutes to work - so let's go for an angled launch, to get a nice smooth arc that will reach a peak of over 70,000m, but have plenty of time to slow back down in the atmosphere.

Underneath your passenger module, place a decoupler. Then underneath, place two FL-T800 (or four FL-T400) fuel tanks. Pop a Swivel engine underneath that, and finally some Basic Fins, for stability.

Example:

Spoiler

The mission

Make sure you have assigned the tourists to all of the available seats in your Mk1 Command Pod, and Mk1 Crew Cabins.

Also makes sure your staging is correctly set up: The swivel engine will fire first, then when it runs out of fuel, you will detach the lifting stage, then activate the parachutes.

On the launchpad, enable SAS, go to full throttle, and launch!

Spoiler

xv9x4WU.jpg

Go vertical until your speed reaches 100m/s, then pitch over to the east by about 10 degrees.

Spoiler

Rz6H8Ah.jpg

Continue pitching over smoothly, aiming to be at 45 degrees by the time you reach 10,000m. Don't stray too far outside of the prograde marker on the navball!

Spoiler

ypMB2M1.png

Hold this angle until you reach 20,000m - then pitch down to about 20 degrees.

Spoiler

PrRDGLk.png

Hold this angle until you run out of fuel. This should put you above 70,000m - check the map with the M key.

Detach the lifting stage.

Spoiler

IqkctiZ.jpg

When you reach the apoapsis, get ready for coming back down by pointing retrograde on the navball, and activating your parachutes (they won't deploy until it's safe)

As you descend, try and keep pointed retrograde as best you can - your craft might start to flip - do your best to stop it pointing nose first! 

Spoiler

Your parachutes will deploy when you are low and slow enough, bringing your craft to a safe landing.

Good luck - let us know how you get on!
