How do I negate falling damage in Starbound?

An easy way would be to use a tech power.

Both the Pulse Jump and the Energy Dash will reset the distance you have fallen. You would have to figure out when to safely activate them (this can also stop your fall at any time).

The other starting tech might be able to stop your fall, but I don't use it so I can't easily tell you (can't do the research either ATM).

A massive amount of water could also stop the fall, but getting the water to an area that you need it to be could be time consuming.

I would recommend the first option, and place some specific identifiers to show when you should activate the second jump or dash.

Extra Info: The Dash can be used over and over (if you have the energy to do it), but the double jump can only be used once (resets on touching ground), but it does not use any energy.
