No video yet?

That's what I'm trying to figure out too.  Was there an actual test flight?

That's what I'm trying to figure out too.  Was there an actual test flight?

Seems to be within the normal posting for grasshopper flights:

flight of 9/21, youtube post on 9/24 
flight of 11/1, youtube on 11/5
flight 12/17, youtube 12/23
flight 3/7, youtube 3/11
flight 4/17, youtube 4/22
flight 6/14, youtube posting on ???

Note those are the date uploaded to space-x youtube channel.  There were some videos shown other times.  For example, I remember I was watching elon on a livestream of some conference when he showed the first hoverslam and he said it was brand new.

But in general, 4 to five days to put on Youtube seems the norm, and while I'm sure a lot of the test engineers are working nights and weekends, the PR department had a weekend off since Friday's latest grashopper flight.

The first place to be learn of new GrassHopper videos is usually Elon Musk's twitter account:

You are indeed correct, and I have him and space-x set up so I get a text when they tweet.

When I posted the list of YouTube dates above, that was easier to find than going through all of his tweets.  But I just checked for the last Hop and it was indeed the same date as the YouTube upload, 4/22 for a test on 4/17.  https://twitter.com/elonmusk/status/326500735233712129

So, we should see the video in a day or two.

Shotwells speech showed nothing new grasshopper wise. Even though the 6-14 flight had already happened. it did show some of other new stuff. like the F-9R second stage test.

Shotwell's TEDx speech appears to have been on June 4th.  (https://twitter.com/TEDxChapmanU

She also mentioned they were five of five on Grasshopper and the 6/14 flight was number six.

The video also contains tests of the upper stage engine. It also contains a video of the first test of the F9 1.1 stage which had engine cutoff a few seconds into the test. We haven't seen these videos before.

I'm going to go ahead and link those videos here for the convenience of other members.

Thanks for linking that, I didn't want to watch it all.

I notice she says "That's a spectacular video" in reference to a Grasshopper failure.

Is that a hint as to the outcome of flight 6?

The talk was before flight 6.  So, while she talked about a potential spectacular video, she was talking about something that could happen, about pushing testing to the limit.  She could not have been talking about the outcome of GH flight 6.

Kinda of surprised that they would
publicly acknowledge
the new grasshopper test (Chris's new article), but not release the video at the same time.  Maybe the PR department is readying new music for this one?  I hope they don't decide that grasshopper tests are getting boring and stop releasing the videos unless they break major milestones.

Space-X has tons of things on their plate, and in terms of communications I would prefer they spend their time talking to Chris than posting a GH video.

Still, its now been longer between flight and video posting for flight number six than it has been for any previous flight, so I hope we see it soon!

I seem to recall Elon saying something like if they didn't at some stage crash GH then they weren't testing hard enough.  Wonder if 6 will be / was it?

We already know GH flight 6 was a success, first on L2 and then publicly:

The latest “hop” of the Grasshopper took place last week, achieving a huge 325 meter leap into the air, before successfully landing after 68 seconds in the air.

So they're a bit slower posting the video than previously; I don't see that turning a success into a failure ...
