Private space in control
Today it was announced that SpaceX has signed an agreement with NASA’s Stennis Space Center to test a new methane engine there beginning in 2014.
This story is significant in two ways:

The next Dragon flight has now been scheduled for no earlier than February 11.
The next flight of SpaceX’s Dragon has been realigned to a February 11, 2014 NET (No Earlier Than) launch date. The launch will mark Dragon’s first ride on the upgraded Falcon 9 v.1.1 rocket, potentially sporting landing legs, as Elon Musk plans his next attempt at proving the rocket’s ability to return its stages back to Earth for reuse.
SpaceX must first launch two commercial satellites with the upgraded Falcon 9 before its NASA flight. Also, 2014 will be a very business year for the rocket, as it is scheduled to send three cargo missions to ISS plus launch eight commercial satellites.
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.
On October 7 SpaceX successfully flew and landed Grasshopper on its highest flight yet, 2440 feet.

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 article also gives some additional details about the company’s first effort to control the reentry of the first stage after launch last week.
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.
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.

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.

It was already expected that this December launch would be delayed anyway because NASA wants SpaceX to complete two launches of the upgraded Falcon 9 rocket before using it to launch Dragon to ISS.
