Latest performance figures for the Falcon Heavy indicates it can launch 2,900 kg on a Pluto bound trajectory - I'm assuming a Solar Escape, since a Hohmann would take decades. "New Horizons" could thus be followed up by something significantly beefier...

May 26 - fourth sucessful landing (third in a row) of Space X's Falcon 9 first stage.
This is not routine, this is NOT routine, this ... ohmy.gif

Youtube accelerated video of the landing, captured by the first stage itself [link]

Amazing video.
With so much success they're gong to run out of room in their processing facility! Might have to stack them up on top of each other soon (not that I'd recommend it!)

I like the comment in the ars technical article:

"It's safe to say the future has arrived."

If they don't start reusing them then there wasn't much point in getting them back, was there?

Yes, now it's a question of logistics that not even the Shuttle had to worry, about given the slow launch pace in those days. The next rocket already is on the way to the pad!

I wonder what a used booster rocket would fetch on eBay.

On October 28, SpaceX released an update on the September 1st anomaly:
QUOTE
The root cause of the breach has not yet been confirmed, but attention has continued to narrow to one of the three composite overwrapped pressure vessels (COPVs) inside the LOX tank. Through extensive testing in Texas, SpaceX has shown that it can re-create a COPV failure entirely through helium loading conditions. These conditions are mainly affected by the temperature and pressure of the helium being loaded.
...
Pending the results of the investigation, we continue to work towards returning to flight before the end of the year.

Return to flight in early January 2017! Quoting from SpaceX's latest update:
QUOTE
December 7, 10:30am EDT

We are finalizing the investigation into our September 1 anomaly and are working to complete the final steps necessary to safely and reliably return to flight, now in early January with the launch of Iridium-1. This allows for additional time to close-out vehicle preparations and complete extended testing to help ensure the highest possible level of mission assurance prior to launch.

SpaceX released a report on the causes of the "September 1 anomaly". Their site has been updated (link) accordingly.

QUOTE
The accident investigation team worked systematically through an extensive fault tree analysis and concluded that one of the three composite overwrapped pressure vessels (COPVs) inside the second stage liquid oxygen (LOX) tank failed. Specifically, the investigation team concluded the failure was likely due to the accumulation of oxygen between the COPV liner and overwrap in a void or a buckle in the liner, leading to ignition and the subsequent failure of the COPV.


The target date for return to flight is January 8, 2017 with the launch of Iridium NEXT from Vandenberg.

Edit: launch delayed to at least January 14 to avoid bad weather and range conflict.

Edit 2: Success! wheel.gif 10 Iridium Next satelites delivered to orbit and first stage sucessfully landed on the drone ship "Just read the instructions", with a clear view of the descent up to and including touchdown.

Not to be annoying about it, but this ISS resupply mission is off-topic for this forum and hardly a "private mission" since it's being paid for by NASA. I think there are more appropriate sites to follow SpaceX's progress.

ADMIN: Agreed re this mission, and all others in support of crewed spaceflight. Discussion of Falcon launch and recovery operations are fine; let's please stick to that rather rigorously in the future. Thread title will be updated for clarity.

You are right, of course, and I should have realized it beforehand.
I have removed the related texts, although I can't remove the posts themselves which, perhaps, a kind admin could do.
Fernando

KIND (OF AN) ADMIN: Done. Thanks! smile.gif

Just to clarify, discussions of all Falcon launch and landing activities are fine, which includes Dragon capsule recoveries. Discussion of mission activities in direct support of crewed spaceflight, not so much.

I hope that was clearer...
