Gas mass fractions of massive, dynamically relaxed clusters, measured through X-ray observations, are a powerful tool for measuring cosmic distances, and have provided strong constraints both on the mean dark matter density and on dark energy. I will present preliminary results from such a study, which employs various modeling improvements and uses approximately twice as much Chandra data as previous work.
