I'm pretty sure NASA has a plan for a manned-mission to Mars within the next 5 years. We have to wait for the orbits to be close enough to make it actually worthwhile and cost efficient to get there and back safely.
Manned Mars trips are not only very very costly, they also are nearly impossible to survive, considering the large amounts of radiation penetrating the atmosphere, aswell as the chemical composition of the atmosphere.
