ISS used for Mars Flight Simulation

[Emil]

Good day,dear friends,

I have a question for all you space fans:

Could the ISS be used to simulate a long duration flight to Mars,by
keeping an expedition aboard the ISS for over a year and half?

And not supplying them with Progress or any other vehicle?

The ISS needs constant boosts and consumables from Soyuz/Progress vehicles, otherwise the ISS would reenter. Even if it could be boosted high enough it still wouldn't have enough area for consumables for the time duration it takes to go to Mars.

In short; probably not.

Not only would they run out of supplies, they would fall out of orbit.

The crew would have no supplies and it could re-enter (like what Izack said). The crew could actually die if that happened.

I believe that with a special mission module attached, the ISS could be used as a test ground for such long duration mission, given that the crew will be relived from doing the regular science, but with two exceptions: (1) landing and work on Mars cannot be simulated (perhaps a 1/3 g centrifuge might provide for that, meaning yet another mission module attached), and (2) irradiation sumulation won't be realistic in the ISS orbit.
