Deploy VS Transport

[Ablac]

I've been using my second planet to mine crystal and Metal and Ben using the Deploy option to send minerals back to my primary planet, never thought of using transport till now, but am wondering what's the difference?

Is transport automatic? Return/Sending or anything special?

Deploy is a one way trip. It costs exactly 1/2 the gas as transport.

Transport is a 2-way trip. The fleet does not touch ground on the target planet, but instead deposits the resources there, and automatically begins the trip back to the sending planet. The sending time is identical to the return time. Because it also returns the the sending planet the gas cost is double that of Deploy.
