In the heat of competition: Amid a slew of SpaceX launch delays in the past month due to the introduction of an upgraded Falcon 9, Elon Musk noted at a student event in Texas on Sunday that the first demo launch of the Falcon Heavy is likely to happen in September, not April as previously announced.

The article is mostly focused on the launch delays of the Falcon 9, which for some of SpaceX’s customers are becoming a financial problem. The company is obviously trying to make sure that further Falcon 9 launches are a success, but the unreliability of its schedule is clearly a reason satellite companies like Eutelsat have signed new contracts with Russia’s ILS or Arianespace. Even with the problems Russia has had with its Proton they have managed a more reliable launch schedule.

Then again, the Proton and Ariane 5 have been around for decades. Their companies aren’t trying to improve them in any way. The delays in SpaceX’s schedule are somewhat understandable in this context. Better to launch slowly with new designs then to have a failure that entirely stops things for months.

Nonetheless, it might be wise for SpaceX to settle on the present Falcon 9 design for awhile, so that they can catch up and make their customers happy. Moreover, the further delay of the Falcon Heavy launch is definitely disappointing.

I can’t resist. I have to post that video here of the Falcon 9 first stage landing and then falling over from Sunday. You can see it below the fold. It is incredibly impressive, because it shows that the stage actually did succeed in landing, though a failure of some kind afterward caused it to tip over. The company says it was the failure of one landing leg, but if you watch the video you can see that the angle of fall is between two legs, which suggests that the cause was more complicated.

Nonetheless, don’t be surprised if by the end of 2016 SpaceX is successfully landing its first stages on every launch.

The competition heats up: SpaceX successfully put its first NASA/NOAA science satellite in orbit today, though its attempt to land the Falcon 9 first stage on a barge failed when one landing leg broke and the stage tipped over.

The first stage however was still recovered as it fell sideways on the barge. The link above includes a picture, which shows that stage lying on its side. The engines might be recoverable, but certainly they have enough material from the stage to do tests and learn a great deal more about how it tolerates the stresses of launch. Commenter Frank provides a link to a video that shows the stage falling over and exploding, something the images I had seen previously had not shown. They might have more material to test, but hardly as intact as I had first thought.

Nonetheless, they have now successfully test fired the engines from last month’s recovered first stage.

The 156-foot first stage booster that carried out that successful landing was taken to the company’s hangar at Launch Complex 39A at NASA’s Kennedy Space Center in Florida and partially inspected. It was later taken back to Launch Complex 40 and hoisted upright via a crane. On Jan. 15, a static fire was conducted. “Data looks good overall,” Musk said in a tweet, but noted Engine No. 9—one of the outer engines—showed thrust fluctuations. He said that there may have been some debris ingestion, but the engine data looks OK and that they would borescope later that night. There has been no word on how that inspection went.

That all nine engines functioned is a very good sign, even if one had issues.
