The first VLab workshop took place at the Minnesota Supercomputing Institute, July 20-23, 2005. It offered an opportunity for scientists involved in research related to planetary materials and/or planetary processes to exchange information and ideas. The main underlying themes were:

1. planetary science grand challenges (thermochemical state of the lower mantle, water in the deep mantle)
2. materials science grand challenges (strongly correlated systems, solid solutions and phase equilibrium, electronic correlation and quantum dynamics in ices)
3. advances in first principles methodologies (methods, approximations, codes)
4. Information technology applicable to materials computations
