Is there a advantage 2 having more than 1 of a certain science part on a given rocket

Title says it.

Basicilly

Is there any good reason to have 2 goo pods instead of 1?

Or 2 labs instead of 1?

ect.

Is it worth anything, or is it just wasted weight?

[DeMatt]

Not really, no. Having two Goo canisters makes it much easier to balance your rocket, and landing two experiments nets you a bit more data than landing just one... but if you're transmitting, you only need the one experiment because you can repeat it, and the other experiments are much easier to balance than the Goo canisters.

Yes because you can store more data.

Transmitting gives you less science.

So basicily, on one given rocket, i could do the same expermient twice, independantly. Like i could take one leaving kerbins orbit, and one entering the muns orbit, and still keep both data samples?

Transmitting, currently, only gives you "less" science in one run of the experiment. The advantage of transmitting is that you can repeat your experiment without having to launch a new rocket. Ultimately, after many repeats, both transmitting and relaunching will give you the same amount of data.

Assuming you're planning on landing your rocket back at Kerbin to retrieve the experiments, yes.

Thing is that you won't be able to keep spamming the same thing in later versions, it'll work now but still, it's going to take longer and for later techs where you'll need longer missions it isn't really time economic.

This is the current behavior as of 0.22. It's been strongly hinted that this may change on 0.23.

Two experiments on the same mission would let you collect and return the results from two different conditions, e.g. the goo experiment above the desert and on the surface of the desert in one launch.

[keoki]

Saving data for a return produces a LOT less science than transmitting a smaller amount of data over and over under different conditions. The goo for example, it can produce about 200 points worth of science when you enter soi of a new body, do some aerobraking, or have other changing conditions. So read and transmit over and over, for every science instrument you have that still produces meaningful amounts of science. If you plan a good flight, you should be able to rack up 2000 science points in a mission.

[Grover]

To pull the thread together then, if yoh have adequate power supply and means of communication, no, multiple science parts are not neccesary, unless you need to balance the rocket (particularly with the goo canisters which are radially attached and really heavy), but if you are playing without transmitting for the challenge, then more parts = more science, either by using different conditions or by gathering all the science there is (usually about 3 experiments of each type from the same place is enough to get most of it) in a single mission

Which is also a benefit to sending multiple kerbals to places, since you can get all the science from the surface samples and surface EVAs in a single mission
