- From the shadows in LO-IV-193H, the east rim of Blanchard is 2300-2600 m above the floor. - Jim Mosher
- Named for Jean-Pierre-François Blanchard (1753-1809), a French aeronaut.
- This name was published in the IAU's 1991 Reports on Astronomy.
- Although listed in the IAU Planetary Gazetteer as replacing the former lettered crater designation Arrhenius P, that name was actually part of Ewen Whitaker's effort to letter the farside for NASA RP-1097 (1982) and was never approved by the IAU. The IAU Planetary Gazetteer listing also gives a map reference of "SOV 1985" for this and the other seven new names published in 1991. This would seem to be a reference to an unidentified Soviet map from 1985.
