The Space Telescope shall be useful to check the local extragalactic distance scale to within 10-15 percent. It opens up the opportunity to determine relative distances of cosmic standard candles, viz. brightest M-superqiants and SNe I in E galaxies. The M-supergiants shall map the velocity field out to vo ≈ 3000 km s-1 thus providing (1) a firm basis for the determination of Ho (global) from local distances; (2) the possibility to derive precise distances of all near by field galaxies from their recession velocities; and (3) in combination with the density profile of the Virgo complex an accurate value of the density parameter Ω/Ωcrit. Photometry of the SNe I out to z = 0.5 shall lead to a direct determination of qo via the Hubble diagram, and the form of their light curves offers a fundamental test on the nature of red shifts. The independent determination of Ω/Ωcrit and qo shall give anestimate of the smoothly distributed, invisible matter in the universe and test the assumption Λ = 0.
