I thought this was settled science ages ago – planet has not enough gravity to hold onto a thick atmosphere, lack of magnetosphere causes the atmosphere to be lost too, much of water has gone, rest has frozen in the sub surface.
IMO no amount of terraforming will solve that. Some FAR FAR off hypothetical solutions have been proposed for some artificial magnetosphere at a Lagrange point but any short term efforts and gains will be a rapidly losing proposition because it will all leak away again.
