Because of its importance in setting the distance scale, the time scale and in estimating cosmological parameters from the CMB, astronomy needs an estimate of the Hubble constant independent of the local distance scale and its systematic problems. This can be achieved using gravitational lenses with time delay measurements given enough constraints on the gravitational potential of the lens. We will use deep NICMOS observations of the lensed quasar host galaxies in 7 gravitational lenses with time delay measurements to obtain the necessary constraints, determine the dark matter distribution and estimate H0. We also request 30 ksec Chandra ACIS images for each of the 2 systems lacking them (B1608+656 and B1600+434) to measure the mass in nearby or surrounding groups and clusters.
