Did anyone notice what appeared to be a jet of gas under the external tank in the DOAMS replay?
I saw it, though it looked more like water vapor dropping from the aft of the tank than a jet.
Yes I'm sure whatever it was took an expanding jet appearance due the aero forces acting on it at those high speeds. I'm just surprised there would be enough water to form that feature for as long a duration as it did. Can anyone pull a screenshot? It was from the Patrick DOAMS.
After reviewing the footage again on my DVR, it appears this jet feature is visible for at least 30 seconds.
I've taken a screen capture of this jet like feature that appears underneath the ET as captured by Patrick DOAMS camera during ascent. What is curious about this feature is that it persisted through over 30 seconds of flight until is was obscured due to the changing angle. What do you think this is?

Could be me, but Booster sounds like the same guy as on the STS-93 video?

My
guess is that you're looking at contrast between the shadow of the tank/right booster on the orbiter belly and the part of the belly on the right wing side that's in the sun. (You can see a similar effect on the other wing.)

I think you are correct. Bad atmospheric seeing in the video made this feature appear to ripple in the video much like a jet of gas would. Thanks for your thoughts!

I think it was the capcom who called up "Lucky Dog" right before the roll to get better comms through TDRSS

I didn't realize that guidance can roll either way on the RTHU. Either the CDR or the PLT is going to get a great view.

Actually it was during the roll. Sounded like it was Ken Ham who said "And Scorch, I got the roll" just after acknowledging the Press to MECO and Single Engine ZZA 104 calls and that's what Charlie Hobaugh was responding to.

Right. Guidance always takes the "shortest" way, but since it's a 180 degree roll it depends on what the attitude error is at the time the roll starts.

Crew heading to sleep shortly. Thanks again to everyone that helped with the updates, and to everyone that followed via our coverage.
Remember, a mission is not just launch and landing, so I fully expect to see you all here, wearing your OBSS Sensor Package T-shirts for FD2 inspections at midday GMT, prompt
FD2 live coverage will begin about 8am GMT.
