Glad to see someone else too checks such things 🙂 But I double checked because of this spooky verse:

"Somewhere between Tuesday and Wednesday your true day must have slipped"
"Maria Nephele", by Odysseas Elytis

If time is still linear (at non relativistic speeds), Sol 663 should come after Sol 649 and before 667, no? So on 663 Ingie was still on the ground where it landed after flight 37. I hope :)
