Is it GoPro looking out of Orion's window? Reflection looked like it.

Answered earlier in the thread.
Answering "yes" or "no" would be easier, but thanks anyway.
Of course it's pressurized.
Should have equipment conditioning as well...

Can't find Orion ephemeris on heavens-above site. How can I know if it's gonna pass over my head in next minutes?
Look at the map on the feed (hint: nowhere near Rome
)

Its alreadfy passed you, plus it was a bit far South for you to see it. It isnt night time in Rome right now, so you wouldnt se it even if it was direct;y overhead.

NASA Centers: Johnson, Glenn, Armstrong, Ames
Glenn, Armstrong, Ames had little to do with operational support.
The UAV is from Armstrong, so they are heavily involved in recovery support.

Anyone here know the duration of the Delta upper stage disposal burn? How much separation will its reentry track have from that of Orion?

Armstrong Center has pilots that will be directing the unmanned MQ-9 flying in the recovery area to photograph the re-entry.

They said it was a 1 minute burn and it looked likely to splash about 250 miles uprange of the Orion.

NASA/DOD did not publish any list of tracking sites for Orion EFT-1.
On NASA TV the commentator mentioned tracking stations participating in the mission: Antigua, South Africa, Diego Garcia, Kwajelein, Hawaii (may have missed one). Any idea what type/city (location) of these stations?
Others I know of are support locations:
Patrick AFB: 920 Rescue Wing, 45th Weather Wing, Range Support Operations
White Sands TDRSS station
Schriever AFB - NORAD tracking
The Eastern Range which is run by the 45th Space Wing's 1st Range Operations Squadron has tracking sites at Cape Canaveral AFS (TEL-IV), JDMTA, and Antigua AS. It is also the lead range for the mission.
The Air Force Satellite Control Network is managed by the 50th Space Wing out of Schriever AFB, CA and has sites at Hawaii, Guam, Vandenberg AFB, and Diego Garcia.
The Army's Reagan Test Site at Kwajelein has tracking assets providing support
The NASA TDRSS has a ground station at White Sands but Goddard SFC distributes the data.
With the orbit out to 3600 miles does the AFSCN tracking reach out that far? How from Earth does a spacecraft need to be where the Deep Space Network has to provide support?
NASA TV also mentioned a South Africa station - type???

DSN is not much use until stuff gets at least 10,000 km out. There are only 3 sites, so it needs to be pretty high until you can be sure one of them can see it.
As far as South Africa, what is now the Hartebeesthoek Radio Astronomy Observatory was originally built as a NASA tracking station, and can still be used occasionally for telemetry, I think. No idea if this is the one they refer to, though.

Does this test flight mean that a significant amount of risk has been retired with respect to EM-1?

Schriever AFB is in Colorado Springs, CO...

Congratulations to ULA, LM & NASA for their success today!

One thing bothered me... & I am no expert in parachute behaviour ...
The main chute performance bothered me a bit. They had an oscillation that caused them to bump into each other and then separate a great distance & repeat. It seems possible that in conditions not too far from today's, they could interfere (tangle or collapse?) with each other.
Was this expected and/or accepted as safe?

Congratulations on a great flight!
But why is it taking so long for them to get to Orion? How far away is the ship?

So, as ORION was falling back to earth, I was watching the altitude on the telemetry display, and it seemed to continuously fall at pretty close to one mile per second. That works out to 3600 mph. Why did it not increase in speed to closer to 5mps? Was I not watching correctly or perhaps looking at the wrong thing?

They've been around 120 yards upwind from it for a while, they are waiting for it to power down.
On normal flights they will power it down pretty fast, they are leaving it running for an hour this time to keep collecting telemetry, thermal in particular.
Based on drone and helicopter footage, they appeared to be further away.
Now a bit of speechifying on the NASA comm with USS Anchorage. Annoying to hear people communicate for "posterity" rather than talking directly to each other.

Seems like it's pretty common for multiple chutes to oscillate like that for awhile. The SRB chutes did the same thing until near splashdown.

Similar behaviour was common on Apollo CM splashdowns as well.

Thank you both for the feedback. I will have to look at some SRB and Apollo CM splashdown footage now!

I took a day off yesterday to see the launch, but I couldn't today, so I missed it. Shame. I did see the splashdown, though.
