KSP 2 Technology Tree

Overview

The Technology Tree in KSP 2 is different from the original game. Introduced in the Science Update, the player must complete missions as well as gather scientific data to progress through every node, and unlock every available part for their vessels.

Research

Split into four distinct tiers, with each tier requiring one specific unlock from the previous to access, the following is each "node" in the tree.

Tier 1

Name	Cost	Description	Prerequisite
Starting Rocketry	0	This is the first step from firework rockets to real rockets. Fly safe, Kerbalnaut.	None
Light Launchers	10	With radial decouplers, we will be able to attach fuel tanks and engines to the sides of our craft, then discard them once they're empty, significantly increasing the thrust and range of our vessels. Pretty cool, huh?	Starting Rocketry
Solid Fuel Boosters	15	A solid rocket booster, or SRB, is a powerful engine with fuel already built in. They are quite useful for providing a huge amount of thrust during the start of a launch, particularly with 2 or more radially attached. Because more power equals more fun, right?	Light Launchers
Environmental Science	10	With the environment scanner module equipped, your vessel will be able to gather more detailed reports from all over the Kerbollar system, which will translate to even more delicious blue science points for every fascinating new location you discover and explore.	Light Launchers
Probes	10	Electronic probes and satellites are vitally important for exploring the vastness of space. Advanced computer-controlled craft can safely explore unknown regions and report their findings before we send our Kerbonauts, saving us time, effort, and snacks.	Light Launchers
Introductory Construction	10	Stuff to build stuff.	Light Launchers
Aerodynamics and Stability	10	Reaction wheels use small gyroscopes to help provide stability without the use of thrusters. It would take too long to explain how something spinning at high speed can hold a ship perfectly still, but trust us, these things really work wonders!	Light Launchers
Orbital Rocketry	25	With this technology we will explore advances in Specific Impulse, or ISP. Engines with high specific impulse are not always as powerful as lower ISP engines, but are more efficient and consume less fuel, making them quite useful in low gravity environments like space.	Solid Fuel Boosters
Struts	35	Do not be deceived by the apparent small size of this technology. Strut connectors can be used in countless ways to strengthen a vehicle and are especially useful for holding together very large craft. Our simulations show that this will be an essential tool for any experienced rocket designer.	Solid Fuel Boosters
Lights & Utilities{{	15	Landing legs on a spacecraft, what a marvelous idea!	Probes
Specialized Decoupling	15	When you need to say goodbye, do it with explosions.	Introductory Construction
Basic Trusses	25	They're trusses, not girders!	Introductory Construction
Survivability	15	Researching survivability will help us to understand and build highly resistant heat shields for our craft. These are especially useful for re-entry into an atmosphere, where temperatures can climb high enough to roast marshmallows, along with the rest of your ship!	Aerodynamics & Stability
Reaction Control System	50	Reaction control systems are very small thrusters designed for stability and control in space. Placing these small thrusters around our vehicles will make maneuvering much more precise and help even the most inexperienced pilot fly like a pro.	Orbital Rocketry
Power Management	35	When it comes to electrical efficiency, nothing beats a well-designed solar panel. These ingenious devices convert sunlight into electricity that can be used to run equipment and also recharge a craft's batteries. Admit it, we all hate when the lights go out.	Lights & Utilities
Small Payloads	35	Investing in payload technology will help us better protect sensitive equipment and cargo, such as electronics, scientific equipment, and most important, snacks. Payload fairings can even help improve aerodynamics and reduce drag during take-off. And make your ship look cooler.	Introductory Construction
Micro-Construction	35	It's surprising how many ways you can use a little square truss.	Basic Trusses
Light Aviation	50	Flying sideways is fun!	Survivability
Mun Landing	80	Because landing safely might be fun.	Orbital Rocketry
Monopropellant Drive	80	Parts designed to physically shove your craft around.	Reaction Control System
Long-Range Probes	50	Antennas are devices designed to transmit and receive radio signals and are a key component for our space center. By investing in better antenna technology, we are able to extend the range we can communicate to even the most distant planets. Impressive, isn't it?	Power Management
Research Miniaturization	50	Studying methods of miniaturizing and compacting our science equipment into smaller, more efficient parts will greatly expand the ways we can utilize them, as well as reducing mass that can be used for other cargo, such as snacks. Science and snacks, what a great combination.	Power Management
Basic Docking	50	Connecting two ships together, or docking, is a cornerstone technology, and essential to our space program. Having the ability to dock two or more ships opens up all kinds of possibilities to transfer crew, fuel, and especially snacks, between ships.	Specialized Decoupling
Tiny Engines	120	As we build smaller satellites and exploration probes, we will need the technology to construct very small, efficient engines to propel them. Despite conventual wisdom, there are times when smaller is much better.	Monopropellant Drive
Power Launchers	180	Power? What can go wrong?	Mun Landing
