Abstract:	We describe the Chow ring with rational coefficients of $overline{M}_{0,1}(mathbb{P}^n,d)$ as the subring of invariants of a ring $B^(overline{M}_{0,1}(mathbb{P}^n,d);mathbb{Q})$ , relative to the action of the group of symmetries S_d. We compute $B^(overline{M}_{0,1}(mathbb{P}^n,d);mathbb{Q})$ by following a sequence of intermediate spaces for $overline{M}_{0,1}(mathbb{P}^n,d)$ .
