Relicta

Since I purposely skipped a few collectibles during the story playthrough, I compiled the below list of the locations for the game’s 17 PDA data cards from the TA Walkthrough (thank you to the TA Walkthrough’s authors) to help me figure out what I had missed. All PDA data cards are found in the station areas prior to the entrance or after the exit from the test tracks. There are none to be found in the themed habitat areas while solving puzzles.

Note: If going back after completing the story to get PDA data cards found in exit areas, travel from Shackleton to the Maglev stop beyond the exit location to backtrack thru the station to the exit way of the prior area.

"About our talk last night..." {1/17) - De Gerlache Forest - top of stairs on box or (if after story complete) your room on bed
"Opportunities Out Of This World!" (2/17) - Shackleton - straight out of your room thru door then 4th door on right in locker
"A brief chronology of the Orbital Era" (3/17) - Shackleton - main hub room on desk with computer
"Relicta list" (4/17) - Shoemaker Taiga - on bench to right of trees
"Angie's Logbook" (5/17) - Shoemaker Caves - maglev station on book on curved bench to right near ice pillar
"Ethical concerns" (6/17) - Shackleton - corner bench before 2nd maglev station door as returning from Shoemaker Caves
"The thing in Ibn Bajja" (7/17) - De Gerlache Cliff - laboratories in green locker
"72': Hostilities Cease” (8/17) - De Gerlache Cliff - exit to maglev station tunnel crates on left
"Chandra expedition hearings transcript" (9/17) - Faustini Canyon - benches between staircase
"Chandra expedition to reopen moon base" (10/17) - Faustini Canyon - exit to maglev station bench on left
"Kwarizmi PRIVATE" (11/17) - Sverdrup Beach - assembly room third table on left
"Ragnar Nguyen's acceptance speech" (12/17) - Sverdrup Beach - tunnel on bench in room at end
"Let The Red Moon Rise!" (13/17) - Sverdrup Beach - exit to maglev station third bench right corner
"Laia's Dirty Secrets Diary" (14/17) - Shoemaker Glacier - testing area on cart in back near teleports
"Orbital Politics 101" (15/17) - De Gerlache River - left corner on book near boxes/canisters
"About biomes and dome maintenance" (16/17) - Faustini Rift - back corner locker after giant purple thing
"Intel requests" (17/17) - Sverdrup Jungle - downstairs room with generators in back on crates

Not sure if its a bug, or intentional. But once you've finished the game, you can hit continue (and yes choose a different ending), and the doors that were locked in the central area when you got your first ending are now green and open. I used this to go back to get a PDA I was missing in Shoemaker. You should be able to mop up any missing collectibles that way.

Sorry, partial solution because I didn't record all the collectible locations. But they are all in the station - and they have a fizzy glow above them. There are 2-3 in each area. 33 entries in total in your PDA ().
