What was the heaviest artificial object to reach orbit of Mars? Delivering the heaviest object of all times should have been quite an achievement in itself. So I'd like to understand the details of stages, masses and fuels of its launch and its flight.
How it was launched? On which rocket?
How it was accelerated? What was the upper stage(s)? When has it separated from its upper stage(s)?
Could the same rocket stages and spacecraft engines deliver any heavier object, or was it close to the limit for the given rocket configuration?
What was the dry mass of the spacecraft, its full mass? How has it utilized its engine after separation from the rocket stages?
How it was braking (an aero-brake, multiple aero-brakes)?
What martian orbit it ended up at?
