Ok, I just tried it and it works via the embedded screen in the forum on my Linux box, but wasn't working on my iPhone through Tapatalk - I thought that something else was going on since I couldn't find it with a search either. Sorry for the false alarm.

Yeah that's okay. :)
I may end up redoing with different audio though!

Protip on YouTube: Never use third party copyrighted audio. You'll get totally random results - some regions see it fine, some see it with ads, some get "blocked by XXXX" - rights to various music pieces are a massive global mess where single piece of music may have dozens of "owners" depending on where you are...

Either completely original music, or music that is specifically released as royalty-free. Otherwise YouTube will make a mess, one way or the other. Worst thing; You may yourself be completely unaware that, say, 80% of the world can't view the video at all because of copyright claims.

Another alternative is to upload another version of it without music, and then link to it in the description of the original video with a "in case you can't watch this, go here" message.

Yeah I'll make a version without music. Wonder if I should integrate the latest landing video...

Edit. But I assume there's a good reason that vid keeps disappearing from NSF, which I'd rather blindly respect.

The video is now public, full story:
3) Thankfully, we now have permission to post this openly, without having to use the links of those who clearly have absolutely no regard for sourcing or accreditation. I appreciate NSF members' patience in waiting for a sanctioned upload, which has been uploaded to one of the CRS-3 Propulsive Landing Video youtube accounts.

Coming up on 420,000 views! And bumping as I saw yet more twitter references to it last night.

It's the gift that just keeps on giving.

And I have to say, SpaceX continue to appreciate it - it's mentioned almost every time a SpaceXer talks to me for the first time. We're working on building a very strong relationship (long term effort, but one that could be amazing for both parties) that you'll start to see more and more over the future. A lot of that will be thanks to this NSF crowd sourcing effort.

I'm sure I'm not the only reader of these fora that gets a smile on his face when there's a "new" badge next to this thread. :)

The video is private. This is the one linked from Elon's twitter, SpaceX's twitter and SpaceX's website. Why is this video private now???

That's an earlier version, it would appear. The channel is here:

... and the final version posted in the channel is here:



I can't tell who owns the XoufUV5oGTo version...

The successful controlled-descent test on CRS-3 has made the 2014 in science list on Wikipedia.    8)

Look at 18 April.

Congratulations to all who were involved in documenting the video return of this historic flight!
Re arguments from authority on NSF:  "no one is exempt from error, and errors of authority are usually the worst kind.  Taking your word for things without question is no different than a bracket design not being tested because the designer was an old hand."
"You would actually save yourself time and effort if you were to use evidence and logic to make your points instead of wrapping yourself in the royal mantle of authority.  The approach only works on sheep, not inquisitive, intelligent people."

Placing you guys on Standby One just in case Emily Lakdawalla needs some help!

I've made the offer and if accepted we'll set up a thread. Lightsail is cool, but Emily is also a friend of the site.

They've asked for help decoding a JPEG:

CROWDSOURCE CALL: Can you help compile a #LightSail image? This JPG is from other camera, but loads as blank image.  http://t.co/YZ3w0JwS5b

The #LightSail image I posted has first 24 bytes removed (metadata), and this header attached: http://t.co/TEDRVQlgXy

Finally, here's the original-original #LightSail image, with metadata intact and no headers attached: http://t.co/COTkDCgcYr Thanks!

LightSail image processing help

Thanks for helping us try to compile LightSail's second sails-out camera image!

Original image from spacecraft:
http://planetary.s3.amazonaws.com/assets/z-misc/2015/1.jpg

The first 24 bytes store metadata like image resolution (1600 x 1200) and timestamp. This is NOT part of the JPG format and is instead removed and used to generate file names.

Our process for creating a viewable image is to:

Remove the first 24 bytes of the file.
Append a header to the beginning of the file.

The header can be found here:
http://planetary.s3.amazonaws.com/assets/z-misc/2015/header.txt

For this particular image, this is the result:
http://planetary.s3.amazonaws.com/assets/z-misc/2015/P01_15878x16388_176-1_T47_3_26_D2_20_0.out.jpg

However, as you can see, the image does not load.

Here's how things look when the process works correctly.

Yesterday's raw sails-out JPG:
http://planetary.s3.amazonaws.com/assets/z-misc/2015/full-sail1.jpg

After removing the first 24 bytes and appending the header, this was the result:
http://planetary.s3.amazonaws.com/assets/z-misc/2015/P02_1600x1200_30-1_T0_47_33_D20_0_70.out.jpg

Well. I looked today, and that does not look like a jpg at all. It's some sort of repetitive message. Looks to be 1024 byte packets. May be telemetry or something.

Within a day after receiving this, the satellite's transmitter got stuck in a CW tone of some sort.  I wonder if this is an early indicator of that problem?

They got that picture down:

http://www.planetary.org/blogs/jason-davis/2015/20160615-lightsail-test-mission-ends.html

No, the undecoded data I posted above is the picture from the "opposite side", described in your cited article as, "But before engineers could get a picture from the opposite-side cameras, LightSail’s radio began transmitting a continuous, nonsensical signal, and the spacecraft stopped responding to commands."

As I speculated above, the repeated patterns found by @saliva_sweet may in fact be the first indicators of the "continuous, nonsensical signal" that LightSail eventually settled into.

The mystery of this lockup beacon is still unsolved.
