Damar Hamlin's incredible road to recovery now includes some new ink ... TMZ Sports has learned the Bills defensive back just got a space-themed hand tattoo to remind him of the healing journey he's currently on.
Hamlin hit up artist Andres Ortega out at Onder Ink in Arizona just a couple days before the Super Bowl to get the piece done ... and it came out amazing.
It covers the entirety of the back of his left hand and wrist -- and features an astronaut hitting a yoga pose in the middle of the Milky Way Galaxy.
