300,000kg of prop. Paracone on one end, engine on the other and it can use the tanks dV to get to Mars.
How would we hold the paracone on, Duct tape? :lol:
Seriosly, are there attachment points on the paracone? the cone also cannot be deployed independent of the braking rocket (which doesn't fire until commanded, but it's still in the way of a clean connection).
What's the window from Mars to Earth after 2018?
The Albatross holds 25,000kg in the refuelling system tanks

The expendable tanker in the same pack holds 60,000kg, which might be a better choice if we was going to use one of the two, both tankers lack the propulsion to reach Mars on their own though
Arrowstar: what kind of mass can we bring back to Earth without adversely affecting the dV requirements? We have requests for a sample return.
How much fuel does the albatross hold?
Surely with a large ship like James cook in orbit this is pretty much a moot question?
I was't so much asking about the space available, more along the lines of fuel budget.
There is a thought - We don't have to bring both XR2's home...... That would allow for extra samples, etc to be brought on board and will lighten the James Cook for the trip home.
The second XR2 could also be used for local missions after the James Cook left, if you plan to keep a permanent mission on Mars.
It was you who demanded that the james cook be used!!!! and so what about the rotating gravity wheel part? You even said that you didn't want to have any sort of mission failures so I'm confused as to why you insist on a gravity wheel?
And Mission OFMM-P1 was going to be posted on Tuesday but I'm confused as to where we are as it's all changing even though you said that the mission plan was fine.
