Speak to Cora on the TempestEdit
Cora requests a favor from Ryder. If Ryder refuses at this time, she'll ask the same question again the next time Ryder speaks to her.
Go to Eos with CoraEdit
Go to the nav point and talk to Cora. She has brought a soil converter. Eventually it will turn sand into something useful, and then with some rain and seeds, it will be a garden. Not for a long, long time, perhaps, but like the asari, Cora has learned to think in the long term. Ryder and Cora then seed the garden.
If Ryder flirted with Cora before and hasn't already locked in a romance, it is possible in this mission to lock the romance with her (timer countdown kiss) or to reject her.
