Ya didn't get what I meant. If the Orion SPS is used to get out of earth orbit it will most likely not have enough propellant to make the return burn.
It does have storable propellant and a restartable main engine.
Then the Orion Service Module will either need larger fuel tanks for the return trip to EML-1 or to refuel. The extra work and cost of handling the fuel will need planning in.
Why? If it happens at all it's going straight there on an SLS upper stage, just like Apollo on the S-IVB. It only needs it SPS to get home.

Only if the SLS is still around. Clongton was asking about using a different LV such as a Falcon Heavy.

No, neither are in the plans
I had guessed that. I suspect using a Delta IV Heavy instead of the SLS is not in the current plans either.

26 multi-kiloton explosions without any one being killed seems very lucky.
26/(2014 - 2001 + 1) = 1.86 about 2 asteroids a year
