What's not pointed out in Figure 4 are the extendable ladders. Once we take off from Duna, they will be ejected to reduce mass/weight. Note that the science bays (Figure 4) are attached to the lander with the radial decouplers. There wasn't any funds in version 0.23.5, which is why the returning portion of the craft is so minimal. You get extra "funds" for the recovered parts in version 0.24 or later, so the more you successfully bring back, the more funds you can recover. If I was designing this in KSP version 0.24 or later, I might have chosen to bring more back to the surface. This is ideal for our planned descent to Duna, getting everything we can from the thin atmosphere for braking.īecause all these parachutes will be used twice, I have also configured their deployment using "Action Groups." I have set the key '0' to trigger the deployment of the "Mk25 High Altitude Parachute" and the key '9' to trigger the deployment of all the rest of the standard parachutes. "Mk25 High Altitude Parachute" does not have as much drag when fully deployed as standard parachutes do, but it has greater drag when not fully deployed and at higher altitudes and lower pressure (compared to standard parachutes that are not fully deployed). Duna has a very thin atmosphere, yet we want to utilize atmospheric drag as much as possible during the descent. Duna has a very thin atmosphere, and we are going to rely on parachutes to do most of the braking on the descent to Duna. The "Mk25 High Altitude Parachute" has Duna written all over it. They serve a double purpose and will be used twice. The parachutes on this command module section are not only used for a safe descent back to Kerbin, but will also be used for descent on Duna. I'll make note in the text of any changes I might have made for 0.24 on up (the latest KSP version is up to 0.24.2 at the time of this writing). The mission was performed, and all images were taken with KSP version 0.23.5.Pack some extra fuel on the rocket to experiment with a "fast return" path, shortening the total mission time to about 1 1/2 Kerbin years, as opposed to the several year trip that it would take using a more efficient return transfer orbit.
KERBAL SPACE PROGRAM PARACHUTE BURNS HOW TO
Demonstrate how to leverage the Oberth effect even for an underpowered (low thrust) rocket stage, and explain why high thrust is more of a convenience, rather than a necessity, once in space.Touch on the topic of Gravity assists a little and distinguish gravity assists from the Oberth effect.Introduce the reader to the Oberth effect.But it's a long journey, and I figure the Kerbals could use company). Design the ship to for a comfortable trip - not wasteful, but not necessarily minimal either (if instead we were to only send a single Kerbal, the rocket could be made much smaller and cheaper.Bring two or three Kerbals to the surface of Duna and bring back all sorts of science.This rocket has no scientific instruments, but it would work to add some instuments and a communications device.So let's go to Duna! ( Duna is Kerbal Space Program's analogue of Mars.) Here are some mission requirements that I set out for myself: The Second stage, or "service module" has up to 800 units of charge, and landing legs if you are crazy enough to attempt a Mun landing. At sea level, the parachute slows the X down to about seven meters per second, which is easily survivable. Once back on a sub-orbital trajectory, the capsule can survive a reentry, but the parachute can not be deployed until you are at about 800 meters per second, or else it will burn up. The command module is capable of holding up to three kerbonauts. This puts the ship in orbit, and from a low orbit can take the ship to the Mun. Once the core stage is out of fuel, the second stage takes over. The boosters gradually fall away as they burn out. The Kerbal X consists of a core stage, with eight boosters. It is used in the "Flight Basics" tutorial, and is capable of orbit and even the Mun.
