Magnets: https://www.kjmagnetics.com/d503-neodymium-disc-magnet (use this exact size and grade if you want it to actually last two years)
I tested N52 magnets and they were too brittle - would fracture. N30 were too weak. N42 was the sweet spot.

Use loctite 480 to bond magnets - print with pla. this is THE BEST adhesive for bonding magnets to plastic if you want this to actually last a two year mission.
