Gerst and Hill playing up EFT-1 as they learned about a bag that didn't inflate and how to recover the capsule from the drink.

Which begs the question: if there's possibility it's a good idea, why didn't you consider it before?

SLS/Orion is capable for ISS but made for deep space, Moon and beyond...

Gerst: Won't speculate on what the astro office thinks about this new EM-1 plan.

Gerst: Prelim findings in a month. Then it goes into the budget considerations (more studies).

I'm no mindreader, and Gerst is always rather deadpan, but they didn't sound thrilled about this crewed EM-1 political request.

Not too surprising that they wouldn't be thrilled.  Changing a plan is rarely something that will make it go faster.

 @NASASpaceflight Not my sense. I think there is a general desire among Gerst and NASA managers to move forward.

I got the impression that they wanted to do this crewed flight also. But Gerst said that if can't be done in 2019, then it's not worth doing at all (i.e., it's better to wait until EM-2 at that point).

The awful Orion to ISS mission is more authorization act than study level. Would be challenging. Orion is designed as a deep space vehicle.

That's the best news of the teleconference. It would be a stupid idea (especially at this point).

What I heard was from Gerst is they always look for the opportunity to get more data from testing: ie. outfitting Orion with crew couches, mannequins... Not specifically crew on board...

9 day free-return trajectory...

I'm wondering why NASA is talking about a 9-day trajectory.  If it's in the Earth-moon plane, that puts perilune at over 10,000 km (see 26th page of the report attached to this post).  I'd have thought you'd want as short a flight as possible.  The trip would be a couple of days shorter with a perilune of, say, 100 km.  Maybe the idea is to be able to brag about going deeper into space than ever before?  Even so, I'd thought it not necessary to go quite that far out.

Yes. Gerst also said a non-crewed EM-1 would allow them to exercise the vehicle more rigorously.
It's curious to me that returning to two ICPS flights, and putting humans on the second, isn't being considered.

There's probably no way of meeting the 2020 deadline that way.

2019 if you listen to what Gerst said.

Argh, it's depressing. Shuttle flew three flights in its first 12 months of operation.
