Hi! At what stage of the Orion Mission, will the separation occur from the SLS?

Also, at what stage will the boosters separate? Will they hold enought fuel to reach Mars?

The SLS boosters will separate first at approximately 2 minutes into the mission. At that point they will have exhausted most of their solid propellant. After that, the SLS core stage will continue to run for a total of about 500 seconds after liftoff, which will then trigger main engine cutoff (MECO). Shortly after that, the SLS core stage will separate from the upper stage and Orion capsule. The upper stage will be either an Interim Cryogenic Propulsion Stage (ICPS) or an Exploration Upper Stage (EUS), depending on the mission.
So, in short, I think the answer to your first question is approximately 500 seconds after liftoff. The answer to your second question is the boosters separate about 120 seconds and they do not hold enough solid propellant to go to Mars.

Also note that the Orion is a short-duration vehicle capable of supporting a crew of 4 for approximately 21 days. A round trip mission to Mars and back will take approximately 1,000 days. In order to support a crew for that duration of time, a separate habitat will be required, and a much more capable interplanetary transportation system will be required to move that habitat from Earth orbit, to Mars orbit, and back.

Thank you for the reply, so would something like a super SLS be required for such a trip or some other kind of ITS? Or will technology in the 2030's have advanced to the point where the Orion Module and another Module will be able to make the trip?

I'm not an expert, but I think Orion is meant to deliver astronauts to the International Space Station. Then another vehicle will take them to the Moon. If they're Mars-bound, another vehicle will take the astronauts to the Deep Space Gateway from which they will travel on to Mars' Station orbit. Then to Mars surface from that.
So, it's kind of like a tag-team race. The baton gets passed to the next vehicle until they astronauts are delivered to Mars. To my knowledge, the Deep Space Gateway has some renderings on the NASA Website, but as for interiors and whatnot, they haven't got that far.
I hope this helps. My crew cabin for our film is based on Orion, but it's something we made up based on the pictures available, and a little creative license; for example on some walls of the Orion right now there are just bats of insulation or capped off pipes. Our ship can't get away with that, we need to have a realistic looking crew cabin, so we are making one in a converted chicken coop in my barn which has unfinished walls.
We are going to use 4 x 8 sheets of foam board from Lowe's, primed and painted, to get glued to the studs. The foam board is also very bendable, so if one needed to make a curve for say, a roof panel, or a wall panel that is supposed to be curved, then it works brilliantly. Once it's painted and the set is dressed, it looks about right.
Best of luck!
-Chris

It will take crews to the Deep Space Gateway or directly to a Mars transfer vehicle. |
