We create fermionic dipolar $^23$Na$^6$Li molecules in their triplet ground
state from an ultracold mixture of $^23$Na and $^6$Li. Using
magneto-association across a narrow Feshbach resonance followed by a two-photon
STIRAP transfer to the triplet ground state, we produce $3\,\times\,10^4$
ground state molecules in a spin-polarized state. We observe a lifetime of
$4.6\,s$ in an isolated molecular sample, approaching the $p$-wave
universal rate limit. Electron spin resonance spectroscopy of the triplet state
was used to determine the hyperfine structure of this previously unobserved
molecular state.
