The next test flight of a version of SpaceX’s Grasshopper could occur in New Mexico in December.

The next test flight of a version of SpaceX’s Grasshopper could occur in New Mexico in December.

The story says this test will be with Grasshopper, but I think that is a mistake. Unless SpaceX is using this name for all its vertical landing test vehicles, the company had said the test vehicle to fly in New Mexico would be a full scale Falcon 9 first stage, with nine Merlin engines, not one as has Grasshopper.

SpaceX has revised the schedule for its next three launches, pushing back two weeks so engineers can review issues with the Falcon 9 upper stage engine.

The competition heats up: SpaceX has revised the schedule for its next three launches, pushing back two weeks so engineers can review issues with the Falcon 9 upper stage engine.

The debut launch of the upgraded Falcon 9 successfully deployed Canada’s Cassiope spacecraft into orbit on September 29. However, after safely deploying its payloads, the upper stage was then set to restart its Merlin VacD engine for a second burn related to SpaceX’s ambitions to create a fully reusable launch system. An anomaly with the restart held no mission impact, but the company’s CEO and chief designer, Elon Musk, did note they expected to implement corrective actions ahead of the next launch. “In the case of the upper stage relight, we initiated relight and the system encountered an anomaly and did not complete the relight. We believe understand what that issue is and should have it addressed in time for the next flight of Falcon 9,” he noted. “We essentially saw the engine initiate ignition. get up to about 400 psi and then it encountered a condition that it didn’t like. We have all of the data from the restart, so I am confident that we will be able to sort it out and address it before the next flight. We just have to iron out some slight differences of it operating in vacuum.”

I find Musk’s vague terminology about the engine issue to be interesting. I wonder if the “condition” the engine “didn’t like” was when the engine exploded, as some have suggested. (I personally am skeptical the engine exploded, however, as such a failure would probably require a much longer delay to deal with.)

Either way, the next few months should be a busy time for commercial space. Not only does SpaceX have two major commercial launches and a Dragon mission to ISS, Orbital Sciences has its next Cygnus cargo mission and Virgin Galactic claims it will be ready to fly SpaceShipTwo with passengers.

The failure of the Falcon 9 upper stage prior to a final engine test on Sunday’s launch may delay the rocket’s next commercial launch.

6:52 pm

The failure of the Falcon 9 upper stage prior to a final engine test on Sunday’s launch may delay the rocket’s next commercial launch.

SpaceX officials said after the Sept. 29 launch that the nonignition of the upper stage did not appear to be of a sort to delay the SES flight for very long. Feltes said SES is will hoping for a launch as soon as October, but added that if it slipped to November the company was willing to wait. The fact that SES will be awaiting details from SpaceX “does not mean that we reject the flight as a qualification flight,” Feltes said. “We still plan to be on the next Falcon flight, once SpaceX has solved the problem. But we need a technical explanation. We do need reignition of the stage for our satellite.”

The government shutdown also means that the Florida spaceport is presently unavailable for this launch (which is hardly a way to run a commercial operation). This fact makes it even more likely that SpaceX will eventually move all its commercial launches to its own spaceport, probably in Texas.

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

4:17 pm

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.

4:13 pm

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:

9:57 am

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.

6:50 pm

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.

12:00 am

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.

9:41 am

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.

1:29 pm

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.

SpaceX has confirmed that it plans to begin vertical take-off and landing tests of a full scale Falcon 9 first stage.

The competition heats up: SpaceX has confirmed that it plans to begin vertical take-off and landing tests of a full scale Falcon 9 first stage.

The tests would be in New Mexico’s spaceport, and are essentially a scaled up version of the Grasshopper tests the company has been doing in Texas. It appears they are going to do these ground-up tests in conjunction with attempts on each future Falcon 9 launch to land the first stage.

SpaceX has signed a contract with MDA to launch all three of Canada’s next generation Radarsat satellites.

9:32 am

The competition heats up: SpaceX has signed a contract with MDA to launch all three of Canada’s next generation Radarsat satellites.

MDA’s willingness to go with SpaceX prior to the September 5 launch of its Cassiope satellite on the Falcon 9 illustrates again the confidence they have in SpaceX. At the same time, this contract is for launches expected to occur around 2018, which is a long way away. Much can happen till then, including the possibility that SpaceX will go bust.

In other words, right now it is the successful launch of Falcon 9 that is of significance, not these new contracts. Only if those launches succeed will these contracts then become really significant.

SpaceX has begun assembly of the upgraded Falcon 9 rocket that will launch its first commercial payload in early September.

8:52 am

The competition heats up: SpaceX has begun assembly of the upgraded Falcon 9 rocket that will launch its first commercial payload in early September.

This launch has been significantly delayed because the company was testing the actual engines to be used in the rocket, and had a series of engine aborts during testing (as outlined in the article above). Once the engines completed a full duration burn last week, however, the way was cleared for launch.

The article is very detailed, and also outlines the other new features of the upgraded Falcon 9 rocket to be flown for the first time in September. I must admit that this list makes me nervous. A lot rides on the success of this launch, both for SpaceX and for the entire new commercial space industry.

With Proton rocket’s most recent launch failure, Inmarsat looks for alternatives.

3:15 pm

The competition heats up: With Proton rocket’s most recent launch failure, Inmarsat looks for alternatives.

The failure and its spectacular nature, all caught on video — oscillating trajectory on liftoff before tipping over, bursting into flames and then crashing — cast a harsh light on Inmarsat’s sole-source decision for the Global Xpress satellites. The company’s stock tumbled on the London Stock Exchange but has since recovered as details emerged about the relatively easily addressed causes of the rocket’s failure.

Inmarsat officials said at the time of the ILS contract award that they received an exceptionally low price in return for booking all three launches on Proton and that the vehicle’s record justified the choice not to include a second vehicle in the Global Xpress mix.

The Russians admitted today that, due to the Proton launch failure two weeks ago, only five more Proton launches can occur this year.

The Russians admitted today that, due to the Proton launch failure two weeks ago, only five more Proton launches can occur this year.

Before the crash they had hoped to get in about nine launches, more than one per month, all of which were commercial in nature. It was my impression that this launch rate was an effort to provide service to their customers as fast as possible, in order to hold on to them. The crash, like the previous Proton failures in the past few years, has given their competitors a window of opportunity to grab the Russian market share. If SpaceX is successful in its first commercial launch in September the competition in this industry will certainly heat up.
