Почему же?
Получается все включения возвращаемой ступени прошли успешно, был превышен крен
Но есть еще достаточно пусков для доработки ступени

Незапуск верхней ступени к многоразовости никакого отношения не имеет и приведёт к переносу пуска SES-8 на более поздний срок. Могут даже вежливо Orbcomm вперёд пропустить.

[igorvs]

Я про верхнюю ступень не говорил. (я не тот твит скопировал, извиняюсь). Справятся

[igorvs]

Вот про 1 ступень

Musk: Rocket booster relit twice (supersonic retro & landing), but spun up due to aero torque, so fuel centrifuged & we flamed out

Between this flight & Grasshopper tests, I think we now have all the pieces of the puzzle to bring the rocket back home.

Там уже 20 фрагментов на орбите. Если это было проитивоспутниковое испытание - тогда успех...

Spacex had a launch into polar orbit, and tried and failed to re-light the second stage. When that happens it usually makes a cloud from propellant leaking out.
Was it going due north or south?
Edit: Ok, so the DANDE satellite posted TLE (two line orbital elements) which makes it possible to track the satellite. It was one of the ones launched on the Falcon 9, and it should be relatively close to the upper stage.
The TLE was malformed, which was a pain, but after fixing them I got GPREDICT to open them. GPREDICT is an open source satellite tracker, used mostly by amateur radio people to talk to amateur radio satellites.
Opened the DANDE elements file, set GPREDICT to show its current location, then rewound time to see if it would have been visible from Eastern Africa.
Indeed it was! Goes nearly straight over Reunion Island. Looks like we have a winner. That cloud is almost definitely propellant from the Falcon 9 upper stage after it failed to restart the engine.
Edit 2: Wrote up my results and included pictures: http://wikkit.tumblr.com/post/62684205892/tracking-a-new-space-ufo
Was it highest in the sky right near 9PM? Did it go from south to north? Can you link to more photos you have seen?

Tracking a New Space UFO
             
Reddit user p0nette posted this image to Imgur and Reddit with the question "Saw this tonight in Reunion Island, what is it ??!"
Here's a full-size crop of the cloud:

If your geography is as rusty as mine was, Réunion is a French island in the Indian ocean off the east coast of Madagascar. I wondered if the image might be related to today's Falcon 9 launch.
When an upper stage doesn't work correctly in space, it often leaves an interesting display. The unburned propellant creates a cloud in space that can reflect sunlight and be visible over a huge area. A previous SpaceX launch caused reports of a UFO over Australia.
Could p0nette's object be the upper stage of the Falcon 9 that was launched this morning? I think it is.
In the press conference after the launch, Elon Musk said that SpaceX attempted a relight of upper stage but encountered an anomaly. So it certainly could have left a cloud of propellant floating in space.
One of the missions on the Falcon 9 was DANDE, the Drag and Atmospheric Neutral Density Explorer, designed and built here in Colorado. They posted "Two Line Elements" to their website after the launch, which give the orbital information of the satellite. While the satellite and upper stage will drift apart over time, early in their orbits they should be fairly close together.
With the orbit data we can rewind time using Alexandru Csete's software Gpredict and find the course that DANDE, and the upper stage, flew over. The rocket launched at 16:00 UTC, here it is just after launch at 16:09 UTC:

Here it is an hour and a minute after launch, after it flew south over Antarctica and then north up the other side of the world:

The yellow circle represents the area over which it could be seen above the horizon. From Réunion, it would have been almost directly overhead, and would have taken some time to cross the sky. Réunion's time zone is UTC+4, so it would have been 9:01 PM local time when it was highest in the sky.
I haven't yet gotten confirmation from the original poster as to when it passed and what direction it was traveling, but this seems like the most likely candidate for the source of the cloud. I'll update further when I find out more.
If you've seen more images of the cloud or have questions, please contact me at wikkit@gmail.com .

По Вашей ссылке:

Normally, SpaceTrack would expect to be listing the six released satellite combinations, the rocket body and maybe a couple of debris items. A few hours after launch, the catalogue was showing 20 items in a scatter of orbit, indicating an explosion.

Правильно ли я понимаю, что 20 - это общее число объектов? Из них 6 спутников плюс последняя ступень?
