Anyone have or know where I can find the latest images of the ESM? I have looked myself but the dates are very old. I want to compare to an image from a ESA video showing the Orion CM and ESM together and there is a dish attached to the back of the ESM.

Theres no dish

Thank you for those images. I have seen those images before. Here is the video: .

The video did come out in 2015.

Looks like that video is just using the Orion CEV service module with ATV-style solar wings instead of the UltraFlex panels from CEV. Note the larger Orion Main Engine and the 4 pods jutting out from the sides for the auxiliary thrusters, among other issues. CEV did plan to use such a dish.

Do we have any reliable statement or estimate for the per-unit cost / cost per build of the Orion spacecraft?

According to this presentation from Edgar Zapata (page 10, pdf warning) it's $980M per-unit production costs if you build one a year, $654M if you build two a year, and $1,672M if you build less than one a year.

That's fantastic, thank you. Interesting to see the Dragon v2 and Starliner cost estimates there too

NASA built the Orion capsule.  For what will it be used?

Orion also was on orbit during its December 2014 flight test (EFT-1) that lasted for about 4 hours 24 minutes.

It is planned to be used atop NASA's heavy lifter, the Space Launch System.

How much hydrazine does the Orion carry for its thrusters?

I'm wondering about the Orion capsule itself, NOT in the service module.

Orion has 12 thrusters for use in-space and during reentry. From what I've read, it's dual-redundant with two separate fuel lines. However, none of the documentation says how large the fuel tanks within the Orion capsule are, or how much hydrazine Orion is actually carrying.
