Ultraviolet spectroscopy of Asteroid (4) Vesta

► Multi-instrument measurements of Vesta's geometric albedo in the UV and visible. ► No UV spectral bluing or lightcurve reversal on Vesta. ► Longitudinal variation of Vesta UV spectral slope matches that in visible. ► Fine-grained howardite matches Vesta's spectrum from 220 nm to 950 nm. ► No evidence of space weathering in the UV-visible spectroscopy and lightcurve.
