SpaceX is denying rumors that the upper stage of its Falcon 9 rocket exploded after completing its mission.

The speculation was spawned in part by the fact that the U.S. Space Surveillance Network is currently tracking more orbital objects associated with the launch than expected. … “Regarding the rumors you may have heard about the Falcon 9 second stage, in short, our data confirms there was no rupture of any kind on the second stage,” SpaceX spokeswoman Emily Shanklin wrote in an Oct. 1 email. “Following separation of the satellites to their correct orbit, the Falcon 9 second stage underwent a controlled venting of propellants … and the stage was successfully safed. During this process, it is possible insulation came off the fuel dome on the second stage and is the source of what some observers incorrectly interpreted as a rupture in the second stage.” SpaceX attempted to reignite the upper stage after payload separation in a demonstration of a capability it will need to place satellites into the proper geostationary transfer orbit. However, the reignition sequence was aborted after a problem was detected, SpaceX Chief Executive Elon Musk told reporters in a postlaunch teleconference.

Anything is possible, but I am inclined to believe SpaceX in this case. Moreover, even if true, the bottom line is that the rocket launch was still a complete success, putting its payloads in orbit as promised.

SpaceX successfully launched its upgraded Falcon 9 rocket today, putting its first commercial payload into orbit.

SpaceX successfully launched its upgraded Falcon 9 rocket today, putting its first commercial payload into orbit.

They also attempted to restart both the first and second stages after separation to test the possibility of eventually getting them back to Earth undamaged.

Two post-mission burns of the boost stage were attempted. The first, involving three of the rocket’s nine first-stage Merlin 1D engines, was successful in slowing its descent into the atmosphere. But SpaceX was unable to carry out a second burn of a single engine after the stage went into a spin and ran out of fuel due to what Musk described as a centrifuge effect. The second burn was intended to further slow the first stage’s descent, and because it did not take place as planned, the stage hit the ocean hard, Musk said. Parts of the first stage had been recovered, he added.

The restart of the second stage never occurred due to what Elon Musk called “minor” issues.

The successes today of both Falcon 9 and Cygnus once again demonstrate the advantages of allowing private companies the freedom to design and build rockets they then own and can sell on the open market. The cost to get these space vehicles built was far lower than anything NASA has built in decades, and both got finished much faster as well.

Getting into space can only get cheaper and faster from here.

When will SpaceX launch the upgraded Falcon 9? We have competing news stories:

When will SpaceX launch the upgraded Falcon 9? We have competing news stories:

  • The Canadian Space Agency sent out a press release today saying Cassiope will launch on September 15 on its Falcon 9 rocket.
  • Elon Musk sent out a twitter report of yesterday’s static fire test, noting there were anomalies and that the launch date is still to be determined.

This is very puzzling. That the Canadian release was sent out today suggests that they have information we don’t have about the static fire test and thus knew they could announce the launch date. That Musk is more circumspect however suggests that the information the Canadians have is not correct.

Update: Stephen Clark at Spaceflight Now has more information. It appears the launch will not happen on Sunday, as SpaceX plans a second launchpad static test tomorrow to iron out the unexplained “anomalies” in yesterday’s static test.

SpaceX successfully completed a static test of the 9 first stage engines of its upgraded Falcon 9 rocket today.

SpaceX successfully completed a static test of the 9 first stage engines of its upgraded Falcon 9 rocket today.

SpaceX’s upgraded Falcon 9 rocket briefly fired nine Merlin 1D engines on the launch pad Thursday, but engineers will review data from the prelaunch static fire test before confirming the mission’s targeted Sunday launch from Vandenberg Air Force Base in California, sources familiar with SpaceX’s launch preparations said.

Today’s static fire test and launch rehearsal of SpaceX’s Falcon 9 rocket was scrubbed.

Wednesday’s static fire test and launch rehearsal of SpaceX’s Falcon 9R rocket was scrubbed.

I hear rumors that there was a fuel leak, but this is not confirmed. Regardless, this scrub could cause another delay of Sunday’s planned launch of the upgraded Falcon 9R with its first commercial payload, as the company wants to do this test prior to launch.

SpaceX has again delayed the launch of its first Falcon 9 commercial launch.

SpaceX has again delayed the launch of its first Falcon 9 commercial launch.

This delay appears to be only one day, from Saturday to Sunday, September 15. The static fire test of the rocket on the launchpad appears set for today, and I suspect the one day delay was to give them more time to analyze the results of today’s test.

Also, this quote from the article shows the risks involved with this first launch of the upgraded Falcon 9:

The launch would be the first for the next-generation Falcon 9-R, designed not only to be more powerful but to have the potential for re-use — that would be the “R” in “9-R” (which Harris incidentally said is pronounced “niner” according to SpaceX CEO Elon Musk).

Space News’ Irene Klotz talked to Musk late last week and found some nervousness going into the launch. “We’re being, as usual, extremely paranoid about the launch and trying to do everything we possibly can to improve the probability of success, but this is a new version of Falcon 9,” Musk told her. [emphasis mine]

The first commercial launch of SpaceX’s Falcon 9 has been pushed back to September 14.

The first commercial launch of SpaceX’s Falcon 9 has been pushed back to September 14.

I must apologize to my readers. I completely missed this news item last week. However, in my defense SpaceX has been unusually tight-lipped this time with information.

The launch itself also seems dependent on a hot fire engine test that SpaceX wishes to do first, which means that the September 14 date might still be pushed back again.

“The [US Justice Department] just stuffed a rag in Barrett Brown’s mouth, as well as his lawyers.”

The case might be complicated, and Brown might have even broken a reasonable privacy law, justifying his imprisonment. Nonetheless, it disturbs me greatly that the government’s response is to silence the man. Something about this stinks.

A FAA waiver granted to SpaceX for its next launch outlines details on the company’s effort to recover the first stage for reuse.

The competition heats up: A FAA waiver granted to SpaceX for its next launch outlines the details of the company’s effort to recover the first stage for reuse.

The first stage will coast after stage separation, and then perform an experimental burn with three engines to reduce the entry velocity just prior to entry. Prior to landing in the water, it will perform a second experimental burn with one engine to impact the water with minimal velocity. The second stage will coast and then perform an experimental burn to depletion.

Elon Musk has said that they will be experimenting with bringing the first stage back safely with each launch of the upgraded Falcon 9 rocket. This waiver now gives us the plan for the first launch. It also shows that they are also considering recovery of the second stage as well.

Assuming the first demo berthing of Orbital Sciences’ Cygnus capsule to ISS goes well in September, NASA has now scheduled the subsequent cargo missions of Cygnus and Dragon for December and January respectively.

The second link above also provides some interesting details about the cargo that Dragon will carry in January.
