Input payload to node properties

i've payload and what i want is to input it to the node properties. But from this node there is no information on how to enter the payload as input. is there any solution ?

Having a glance over the code in the node (assuming your using node-red-contrib-satellites) , I don't think you can populate the TLE1 and 2 fields from a message - I think you have to copy and paste the data into them manually

I’m assuming this is a contrib node?
What you could do is open an issue on the nodes github page.
Include the functionality you would like, why the benefit of that functionality would be and how you would use it. Hopefully it’s something the author could add in a future release

Where do you get your data from ? The 'satellites' node retrieves this information from http://www.celestrak.com/NORAD/elements/x

You could modify the node to use your own url instead
