Abstract
CFT construction of S-branes describing the rolling and bouncing tachyons is analyzed in the context of a -noncommutative deformation of minisuperspace. Half s-brane and s-brane in the noncommutative minisuperspace are analyzed and exact analytic solutions, involving the noncommutative parameter and compatible with the boundary conditions at infinity, are found. Comparison with the usual commutative minisuperspace is finally performed.
