It would contribute the equivalent of nearly doubling the size of other near term cosmological surveys like DES, BOSS and Pan-STARRS. We are building a new distance ladder to double the current precision of the Hubble constant to <2% by attacking the largest unaddressed obstacle to its determination, the lack of parallaxes of long period Milky Way Cepheids. We have developed a new technique to measure relative astrometry of bright stars and their parallaxes with WFC3 using spatial scanning, improving upon the previous best relative astrometry with the HST FGS by an order of magnitude to reach distances of 1-4 kiloparsecs. A new scanning mode, serpentine spatial scan, is available in Cycle 21. It allows us to avoid saturating observations of Milky Way Cepheids with P>25 days which would otherwise be too bright. Measuring the luminosities of these Cepheids is vital to calibrating their analogues visible to HST in distant galaxies which host type Ia supernovae. With Planck CMB data already in hand, this new measurement of the Hubble constant will more than double the precision of the dark energy equation of state, may reveal a new species of neutrino, and would further HST's legacy in the measurement of the Hubble constant, a task for which it was launched.
