Looks good to me! I confirmed the homepage change and that the s3-redentials endpoint README is there:

Thanks! Waiting to unset draft to get a nod from our programmers.

@quixrick I'm adding the OB.DAAC s3credential endpoint to the earthaccess package. Pinging you for awareness and to confirm that the OB.DAAC uses the same provider ID for cloud hosted data that it uses for self-hosted data, correct?

[quixrick]

Our cloud provider is "OB_CLOUD". Otherwise, this looks okay to me. 👍

@jhkennedy Your review (which, while appreciated, came earlier than desired) was abrogated when I unset draft. Ready for review now, please & thank you.

Nice! just a note, S3 credentials are also picked up from the metadata if they are available. Eventually these hard-coded values should go away, in real life I don't know how good metadata will be from CMR cc @jhkennedy

[itcarroll]

@betolink These hard-coded values would still be needed for earthaccess.get_s3fs_session(daac="OBDAAC") though, right? Maybe that would go away too?

[betolink]

Yeah they are still needed for that. Only when we use the results to download or open is when we don't really need them if the metadata is right. I guess they won't go away anytime soon.
