Tech Tree. What should I choose next?

[DuelRevolvers]

I need help choosing what I should pick next! Please!

Thanks

[Superfluous J]

Bottom of the tree, IMO. Always go for more science experiments.

[Tortoise]

Pick whatever can get you more science, for now. When you get farther, pick whatever can let you build more efficient crafts.

[AeroAviation]

More science equipment and when you have the chance GET NUKE ENGINES!

[Tex_NL]

Nukes are overrated within Kerbin's SOI. I agree with 5thHorse and Tortoise: go for the science parts. They are an investment in your future and will pay themselves back in one or two missions.

[AeroAviation]

I meant for longer missions to distant planets (Since I just landed on Duna with the help of them)

[Xavven]

It depends on what your next missions will be. I usually go for docking ports as early as I can so I can detach separate landers, but some people just do direct ascent missions and don't find as much use for them.

Funds have somewhat killed the whacky aspargus designs... still, I'd go for fuel lines soon. I still use small aspargusing in my upper stages.

I don't asparagus my lower stages anymore though.

the top priorities for me:

docking ports

Science parts

fuel lines

nukes

turbojets

[Liowen]

Well pre .24 I use to go science---solar panels----fuel lines----docking ports. To me this made the most sense, but others go different routs. I guess it depends on what you feel you need to complete a set of goals.

[Pecan]

You should choose whatever will help you most in whatever it is you want to do next and how you want to do it. Since we don't know how you want to play and what you want to do our advice is pretty useless.

FWIW: always go for survivability. This might work in KSP as well.

[EtherDragon]

When in doubt, I always go for the node with new Science! instruments.

Heavier Rocketry. Larger rockets are always the answer.
