Mars surface to low Mars orbit is around 4.3 km/s delta V, compared with 9.3 km/s for Earth surface to low Earth orbit. The first stage of the Saturn V rocket (~2500 t) by itself was able to give 2.7 km/s to the 736 t of stages 2 & 3 + payload.
So, making a space vehicle able to do that is a known factor.
But the progress in actually making one is zero.
Simply because we haven't got a decided mission profile, we haven't got a rocket design to take such a vehicle to Mars.
Once the mission parameters are established (we get how many people on Mars, and how long do they have to stay) THEN work on actually making that vehicle, along with the rocket to actually send it to Mars, could start.
At this point, your question is a bit like calling the local pizza join and request a pie; I am sure they would assure you that they can make it, but you need to settle a few details: how many people is it supposed to feed, and what toppings are desired.
