How close to being completed is a space vehicle capable of achieving an escape velocity to leave Mars?

    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.

    Even though Mars is bigger than the moon, a lander can be built right now to leave Mars. The challenge is carrying enough fuel to lift off again from Mars. So far we've had no interest in doing that. All of our probes have been designed for one way trips, except for the manned moon landings.

    Such a vehicle exists now.

    The problem is getting it to the surface of Mars with all systems ready.

    That is a work in progress

    See this web page

    It could happen by 2026.

    Probably 2030 is more realistic.

    Note that that only brings a few Martian rocks back to the earth -- not astronauts.

    For astronauts, 2060 is a realistic date

    Completed...?

    I'm not sure it's even begun...

    You mean one that will allow the crew to survive?

    Still being discussed around a drawing board.
