Can anyone viewing these HD highlights estimate the fraction of video that shows views of the earth?  My guess is about 1%.  To me the only reason for taking an HD camera up there is to show earth views. 

If you want earth views, download the Earth Day HD items.  Earth in HD as recorded by astronauts for NASA's annual HD transmission.

I like these Shuttle/ISS HD clips for the high resolution looks at the hardware and station segments and astronauts.  I've seen enough earth views on TV to fulfill me - I just need to get into space to see that in person.   

Back to TV, I can't get enough hardware/tech stuff!

STS-129 FD7 HD highlights.   A fun package today!  One of the first or very rare HD footage of inside a Soyuz, a tour of the ISS from end to end, and footage of celebrating the birth of a child!

about 420MB, H264 format.

FD6 HD crew choice downlink was approx 12 min in length - as shown on live NASA TV before crew sleep.

ok, I'll keep my eyes open and see if I can find a refeed later this mission when the HD channel goes to airing earlier HD packages in random order instead of a slate.

The file you posted is indeed a portion of the FD 6 HD downlink - 4 of the 12 mins.

Thanks again for your work in giving many of us access to HD stuff we'd never get to see otherwise.

There were no FD 11 HD highlights.  Hopefuly before the shuttle retires, we get to see the RCS hotfire and other end of mission checkout activities in HD.

STS-129 Landing in HD.  H264 format.

http://www.filefront.com/15013261/sts129-landing-hd.mp4/

STS-129 Landing Engineering in HD - H264 format.  Only a partial package but still quite a bit of the camera views including the heads-up display view.  NASA TV apparently started very late after landing in airing these and my timer recording wasn't long enough to get it all.  I'll lengthen my recording for the future missions to account for the landing replays not concluding within an hour after landing.

http://www.filefront.com/15017567/sts129-landing-replays-hd-partial.mp4.001/

http://www.filefront.com/15018009/sts129-landing-replays-hd-partial.mp4.002/

My second landing try timer recording happened to capture the astronauts doing their traidional walkaround/inspection of the shuttle so I decided to encode it and make it available.  H264 HD format:

http://www.filefront.com/15014709/sts129-postlanding-astronaut-walkaround.mp4/

This concludes STS-129 HD material coverage unless a mysterious Flight Day 6 package refeed happens or someone has a raw feed for me to process and upload.

HD feed is gone as I type this, btw.  I'm surprised they didn't run flight day HD highlights for a day before taking it down.

Back in town.  For the record, my logging only goes back to midday Sunday the 29th, and by then the HD service had dropped.  Oh, I see above that rsmath reported it down by the night of the 28th.

See you in February!

Someone who works for NASA has informed me of an upcoming satellite change.

AMC-6 is having solar array issues so NASA Television (and the HD service in that digital signal) are moving to AMC-3 C-band - 87 degrees West longitude, transponder 15H on or around the weekend of January 16, 2010.

As far as I know, the AMC-7 NASA TV service is staying as-is.

The move not only means moving from AMC-6 at 72 deg W to AMC-3 at 87 deg W, but also changing polarity from AMC-6's V polarity to AMC-3's H polarity.

If you have any questions (dish-related), you can PM me and I'll see if I can answer them.  I don't work for NASA so I can't speak as how NASA decided where to go but the move was necessitated by AMC-6's issues that could worsen and lead to a sudden satellite failure.

There used to be a thread dedicated to NASA HDTV but that seems to have disappeared, so I'll start a new one for this.

First - if you go to http://nasa.gov/ntv you will now see a "schedule" button on the left side which lists all the channels at the same time.

And for those who use thir own dish --

Someone for whatever reason moved the NASA thread into the "Live NASA TV/Camera Audio/Video Links" thread.

Second, the revised "schedule" is missing the HD channel so you have to continue to find out HD events in other ways.

FYI, this is going to be a hot switch.  There will be no period of overlap so you can't schedule your rework effort :(

schedule my rework effort??? not sure what you mean by that.

I'm all set - both my c-band dishes are fully steerable across the north american arc so all I have to do is change the frequency/symbol rate of my batch recording files so that my computer sat tuner will tune the correct frequency/symbol rate when the event launches.

Increasing the symbol rate of the signal is a good thing, IMHO.  I think it means 24/7 NASA HD is on the horizon since they are getting extra bandwidth in the signal with the symbol rate change.

Actually, this change sounds like it will be more noticeable throughout the year, as noted in the advisory file:
ftp://ftp.hq.nasa.gov/pub/pao/tv-advisory/nasa-tv.txt

"News networks, their reporters, and other broadcast media organizations must tune their satellite receivers to the Media Channel to ensure reception of clean feeds for all mission coverage, news conferences, and other agency distributed news and information. News and other media organizations will no longer be able to rely on content from the Public Channel for clean feeds of mission and other agency activities."

(My emphasis.)

I've noticed that the Video File on the Public Channel is now targeting short attention spans.

I'm almost excited when it talks about "clean feeds for all mission coverage" -- could that mean no PAO :) !?!?

No, it's always been the same other than the one PAO-less test.

So those of us who are nerds need to retune to the media channel during missions?

Unsure at this time, all we have to go on is the statement which psloss noticed.
