It will take years to evolve from the Aries 1 human transport rocket to using the Aries V vehicles for heavy launch,
and the are made as compatible systems.
The solid boosters that have been used for decades will be used in concept as the first stage column booster, 5 segments.
The shuttle uses 4 segments on each side, plus the skirt segment, and the nose segment.
Aries adds a stge, uses the skirt, eliminates the nose and replaces it with an aero-fairing.
Liquid fuel 2nd stage mates to capsule/module, and tractor rocket (Rescue).
Seats six, refurshible capsule.
Aries V is larger than the Shuttle tank, back to the size of the Atlas V, but updated to todays material science.
It includes the use of the solid boosters, and maintains compatibility characteristics with the Aries 1 system.
Heavy lift, unmanned drone to carry and deliver supplies.
ISS supplied by Aries V, cargo staged in lunar parking orbit, tragectory placed supplies
in 2 or 3 month intervals in transit points on path to Mars
for rendezvous and re-supply and waste containment stops going out and coming back.
You have to have food and water, and dispose of used items and waste managment.
Command Module can fly to and mate with cargo vessel or transit vessel, use it to propel and direct to next rendezvous, & piggy back onward.
Meeting with orbiting landing craft, they can land a protective pod and supplies for a fun weekend for 2, all expenses paid.
Departing the Mars Landing site, they could leave a function pod housing for the next crew to occupy during a future excursion.
After Mars departure, and re-mating with a pre-staged transit vessel, and start the return voyage.
It's at least 6 months travel each way, so you have to deal with food, water, medical necessities and waste managment for a year.
30 days of trash accumulation, water recycling, and air purification is quite the task to overcome.
And you have to do it without error - at least 12 consecutive times.
This is what the Constellation in beeing designed for.
In the meantime, NASA has a lot of solar panel, battery development, and ecco system work to do and develop.
why not start that work now with the intent to use it now on the earth to make the shift to energy independance,
funded and performed by NASA, and reap the early benefits in tecnology,
and as it advances - the advanced results will become the flight hardware.
Rememember the Jupiter and Saturn Fly-bys? We launched those before the was electronic equipment capable of receiving their signals.
We had two years to make receivers before they reached their destinations.
There is a 20 year window to perform the
Constellation missions, and many gains to be made and profited from.
