Check your codex, it should tell you how many you've scanned on mars. If you're absolutely certain you've scanned at least 3 on Mars, and the codex confirms it, then I think there should be a tick next to that requirement when you hover over the junction. Maybe include some screenshots (upload to a site like Imgur)

Are you holding it down until the scan is complete? I think there's only 5 fragments on Mars. Once you've scanned all 5, you can't scan them again. It sounds like you're not scanning them properly, or maybe aborting the mission perhaps.

Do you have a scanner equipped, and have you been manually scanning them?

Perhaps a silly question, but did you buy it through the PSN store?

Yeh, has to be either max rank, or at least polarized to be able to rename.

Is it max rank, or have you put at least 1 forma into it?

Whether you're MR1 or MR28, the answer is still the same; level up stuff you haven't leveled yet. Just check your profile.

Your issues with k+m on xbox have nothing to do with this 2+ year old thread. The functionality broke in the most recent update. DE are aware of it and will hopefully have it fixed. I doubt you would be able to get a refund.

It's a known issue. There's nothing else you can do about it until DE fix it.

Just complete the node required for the 2nd sortie. Sometimes they bug and think you haven't unlocked the base node. Then you can do the 2nd mission and go on to complete the sortie.

Usually it takes about 4-5 if you get lucky. As already mentioned, infuse the highest first. If you can get one that's at least 38% and infuse it first, I think it'll take 5 weapons to get to 60%.
