SpaceX sets February 6 for first Falcon Heavy launch attempt

10:43 pm

Capitalism in space: SpaceX has now scheduled February 6 as the date for its first attempt to launch its Falcon Heavy rocket.

I was amused by this tidbit from the article:

While a launch date has been set, the company still faces a regulatory obstacle ahead of the launch. The Federal Aviation Administration’s Office of Commercial Space Transportation has not yet issued a launch license for the Falcon Heavy, a requirement for a commercial launch such as this. Such licenses are often issued days ahead of a launch.

I dare the FAA to deny this launch a license. I just dare them.

Bad times fall on Russian Proton rocket

10:24 pm

Link here. The key quote is this:

All this means that after 53 years in service, the venerable Proton rocket might set an anti-record in 2018 by flying only a couple of missions. And, for the first time since its entrance onto the world market at the end of the Cold War, it may not bring any money to its cash-strapped developer.

This story confirms much of what I have been reporting about Proton and the loss of its customer base in the past three years.

Video of Falcon Heavy static fire test

8:39 am

I have embedded below the fold the video that SpaceX has released of yesterday’s Falcon Heavy static fire test. This is the first footage I have seen that allows one to make a good estimate of the test’s length, though because the video has one edit during the firing the time length could have been edited.

The video makes it appear that the firing lasted seven seconds. Witnesses however suggest it lasted about twelve seconds, which was the length expected. The difference raises some questions. If the video was edited and the actual test lasted twelve seconds, one has to ask why SpaceX edited their video. Was there some proprietary information that SpaceX was protecting that would have been revealed had it kept the view locked on the close-up camera for the full twelve seconds? Or was there some issue that occurred during the test that they do not yet wish the public to see?

If the test did last only seven seconds, not twelve as planned, was there instead an issue that caused them to shut down early?

I’m not sure what to think. I am also of the mind that I might be over-analyzing this. Other footage from farther away suggests the test was for twelve seconds, as described by witnesses. The footage however is also not definitive. The trees prevent one from seeing exactly when the firing starts and stops.

We will have to wait and see what SpaceX does. If it schedules a launch relatively quickly, then all this analysis is what I suspect, mere junk. If not, or if they schedule a second static fire test, which was always an option, then this analysis is brilliant.

Personally, I prefer the former, not the latter.

The Falcon Heavy vs the Saturn 5

9:01 am

As SpaceX prepares for what it hopes will be the first static fire test of its Falcon Heavy rocket today, this article provides a nice detailed comparison between the new heavy lift rocket and the Saturn 5, the biggest rocket ever built and successfully launched.

But where the Falcon Heavy comes out ahead is in economy. The estimated cost of a Saturn V launch in today’s dollars is a whopping US$1.16 billion. Meanwhile, the upper estimate for Falcon heavy is US$90 million. That’s million with an “M.”

So, which rocket comes out ahead? In terms of sheer numbers, the Saturn V wins hands down, but the contest is a bit unfair. Saturn V was a Cold War project with a main objective to put a man on the Moon as part of the struggle to prove the superiority of the Free World over the Soviet Union. It was a cost-is-no-object machine intended to win a bloodless battle for world supremacy.

Falcon Heavy, on the other hand, is a business venture. Its job is to make a profit for SpaceX’s investors and its development always had one eye on the ledger at all times. Its design is different, its function is different. To compare it with the Saturn V is a bit like comparing a nuclear strike carrier with the Queen Mary 2. Beyond a certain point, the exercise becomes meaningless.

Read it all. The comparison is quite fun, especially if you are an American and proud of our country’s history in space. To date, no one has built a rocket that truly compares with the Saturn 5. And now, today, an American company is proving that such rockets can be built in the future, for an affordable price.

Detailed update on Falcon Heavy static fire test set for later today

8:42 am

Link here. The article has a lot of good information not only about the test but about the launchpad and how it will be used in the future.

One take-away that I came off with however came from the picture of the Falcon Heavy on the launchpad. It made me realize how far apart the two side stages sit from the core stages, as the rocket is now reconfigured. My impression of most strap-ons today is that they are placed very close to the core, and they generally have aerodynamic cones that slope away from the core, so that the air is directed away from the space between the stages. Falcon Heavy however has all that space, and the side strap-ons have rounded cones.

I wonder if this is one of the rocket’s most worrisome unknowns, as it travels through Max Q, the period shortly after launch when the stresses created from its speed and the atmosphere are the highest. As designed, a lot of atmosphere will travel between the stages. While this isn’t entirely unique (the shuttle had a somewhat comparable gaps between its various parts), I do wonder.

Falcon Heavy static fire test scrubbed for today

11:19 am

Capitalism in space: SpaceX decided to scrub its Falcon Heavy static fire test today soon after they had loaded propellants into the rocket during countdown.

No details, but it appears to me that they are taking this test very seriously, and approaching each step with care. This was the first time they had loaded the entire Falcon Heavy, and I am not surprised they saw an issue that made them hesitate about continuing.

Falcon Heavy prepped for static fire test

10:29 am

Capitalism in space: SpaceX has raised its first Falcon Heavy rocket onto the launchpad in preparation for the static fire test required before the rocket can do its first launch.

SpaceX’s first Falcon Heavy rocket has been raised vertical at pad 39A for the second time in advance of a planned hold-down test-firing of its main engines tomorrow during a window that extends from 1-7 pm EST (1800-0000 GMT). Kennedy Space Center employees were told to expect an estimated 15-second firing.

An update on Zuma status

8:54 am

Link here. The article provides a nice summary of all the reports on the SpaceX launch and its mysterious top secret payload Zuma, including outlining the various failure possibilities. The one scenario they do not mention, however, is that the failure story itself is entirely bogus, a misinformation campaign by the unknown government agency that launched it.

I have no idea what happened, though it still appears to me most likely that SpaceX’s rocket performed as contracted.

SpaceX military payload might have been lost

3:42 pm

Anonymous sources are suggesting that the top secret government payload that SpaceX successfully placed in orbit two days ago might have been lost.

Very little is presently known. Statements from SpaceX suggest that its Falcon 9 rocket worked perfectly, which would suggest the problems occurred after second stage separation. However, one source seems to suggest otherwise.

Until I get more information, I am therefore still counting this launch as a success for SpaceX.

Falcon Heavy on the launchpad

8:18 am

Capitalism in space: SpaceX has finally rolled the first Falcon Heavy rocket out to its launchpad in preparation for at least one static fire engine test prior to is first launch.

SpaceX engineers are expected to conduct a fit check and complete other tests at pad 39A this week, followed by a hold-down firing of all 27 first stage engines some time after New Year’s Day. The company has not set a target date for the Falcon Heavy’s first liftoff, but officials say the launch is targeted in January, some time after the hold-down hotfire test.

Should it launch successfully, the Falcon Heavy will be the most powerful rocket in the world.

Update: They have now lowered the Falcon Heavy to a horizontal position. I suspect that the raising and lowering were both part of the fit check tests, and that they will soon raise the rocket up again.

First flights of commercial manned capsules in 2018

9:06 am

According to a NASA presentation last month, it appears that both SpaceX and Boeing are aiming to complete both their first unmanned and manned flights this coming year.

The schedules remain tight, but SpaceX plans to do its first unmanned demo mission in April, followed by a manned flight in August, while Boeing’s first unmanned flight is set for August, with the first manned flight in November. If these schedules happen 2018 should be quite an exciting year.

The SpaceX light show yesterday

9:12 am

Falcon 9 launch, December 22, 2017

Numerous news articles today have noted that last night’s launch by SpaceX of ten Iridium satellites produced a somewhat unusual light show for Californians. Reader Frank Kelly sent me some images he took, noting,

I was able to catch the booster ascent, stage separation, second stage burn and what looks like the booster spinning with at least one engine firing. The spinning went on for a while so it must have had some fuel left.

I read SpaceX said they would not land this booster so maybe they had some fun with it for us folks in LA. It spun around for a minute like a pinwheel. A great show.

close-up of first stage maneuvers

The image above right is one of his images, reduced in resolution to post here. Below that is a cropped section of the full resolution image, showing the “pinwheel” being performed by the first stage. And as other readers of BtB have also noted, the launch crew was clearly performing engine tests and maneuvers with this first stage, all the way down to the ocean.

As is typical of SpaceX, they waste no opportunity to test their equipment and find out what it can do, on the extreme. I suspect these maneuvers were designed to push the first stage’s ability to recover from an out-of-control spin. From the call-outs by engineers during the launch, it appears that this test was a success, as it appears from those call outs that the first stage “landed” properly upright in the ocean.

Let me add that in reviewing some of the youtube videos posted by my readers in the comments below, I also think these first stage maneuvers might be tests in preparation for the first Falcon Heavy launch, which will involve landing three first stages at the same time, two landing very close together at Kennedy. The flight tests yesterday could be an effort to demonstrate how well they can program those first stages for their return.

SpaceX successfully launches 10 Iridium satellites

7:45 pm

Capitalism in space: SpaceX today successfully launched ten 10 Iridium satellites.

This launch for Iridium reused a first stage from a previous Iridium launch. This was the first time Iridium launched with a used first stage. SpaceX did not try to recover the stage, which could be for several reasons, including the possible desire by the customer that they devote their entire effort to getting the satellites in orbit.

This was also SpaceX’s last launch for the year. The launch standings for the year now are thus:

29 United States
19 Russia
18 SpaceX
15 China

Sometime in the first week of 2018 I will post a full table showing this year’s launches plus the launch totals going back to the early 1980s. It reveals a great deal about the history of the launch industry for the past half century, as well as where that launch industry is likely heading in the coming half century.

Musk releases pictures of assembled Falcon Heavy in hanger

9:40 pm

Falcon Heavy in hanger

Capitalism in space: Elon Musk today tweeted several pictures of the Falcon Heavy rocket, assembled in its hanger at Cape Canaveral and awaiting roll out for its first static fire tests on the launchpad.

As I will have nothing to do with Twitter, I must thank reader Michael Phillips for emailing me the photos. The one of the right I think shows the most detail. Note that the two side stages are previously flown Falcon 9 first stages. Only the central core has not flown before. According to previous reports, it required significant redesign to work in this configuration.

There is as yet no word on exactly when the roll out and launchpad static fire tests will take place, but all indications suggest it will be very soon. Whether the launch itself will follow several weeks later, as the link above says and has been stated many times by SpaceX, is more questionable. Remember, they have never fired all 27 engines of the threefold first stage at the same time. I am expecting that they will need time to review the data from that static fire test. I would be very surprised if their analysis and any changes it calls for will be doable in only a few weeks.

SpaceX launches Dragon and lands 1st stage

11:48 am

Capitalism in space: SpaceX this morning successfully launched a previously used Dragon cargo freighter to ISS as well as once again successfully landing the previously used first stage.

This was the first time NASA agreed to the use of a previously launched first stage. With the first stage and capsule both reused, only the second stage and one out of 10 Merlin engines was new and will not be available for further reuse.

I have embedded the launch video below the fold.

The standings for the most launches in 2017, as of today:

28 United States
18 Russia
17 SpaceX
15 China

Note that I am counting Soyuz launches for Arianespace out of French Guiana under Arianespace, not Russia. Also, the U.S. total includes SpaceX. I have separated SpaceX out to show how a single American company is competing aggressively with whole nations.

Wall St pushes to have SpaceX save Tesla

9:36 am

Three articles in the news today illustrate both the corruption of the press as well as a desire of one analyst on Wall Street to convince Elon Musk to use his success at SpaceX to save Tesla.

All three news articles are based on a single recommendation made by one Morgan Stanley research analyst. Thus, the headline in the first article is an outright lie. There isn’t growing speculation, there is one guy with an opinion, an opinion by the way that Elon Musk doesn’t appear to share, according to the third article.

Musk said last year that there was too little cooperation between Tesla and Space Exploration Technologies Corp. to justify merging the two, dismissing the idea that had been raised by one of Jonas’s colleagues as “quite tenuous.”

From SpaceX’s point of view, combining these companies makes little sense. It would essentially be using the success of SpaceX to prop up Tesla’s financial weakness.

Musk of course controls both companies, and can do this if he wishes. If I was Musk, however, I would keep the companies separate, and let the chips fall where they may. Musk however might care enough about Tesla that he might want to save it, using SpaceX’s profits. If he does, however, he will instantly weaken SpaceX, as it will then no longer have as much cash available to pay for its future plans, such as the Big Falcon Rocket.

China launches another military satellite

8:46 am

The race between Russia, China, and SpaceX for the most launches in 2017 tightened today with another successful Chinese launch this morning of a classified military satellite using its Long March 2D rocket.

The race as of today:

27 United States
18 Russia
16 SpaceX
14 China

According to this article as well as SpacflightNow’s launch log), China, Russia, and SpaceX all have three more launches scheduled in 2017. If that is what happens, these standings will not change.

Tesla aimed for Mars will be the payload on first Falcon Heavy launch

8:51 am

Capitalism in space: Elon Musk announced today that the first test launch of a Falcon Heavy rocket next month will carry a Tesla car which will be aimed for a solar orbit about the same distance from the Sun as Mars.

Payload will be my midnight cherry Tesla Roadster playing Space Oddity. Destination is Mars orbit. Will be in deep space for a billion years or so if it doesn’t blow up on ascent.

Musk definitely knows how to generate publicity, even as he lowers expectations for the launch. Richard Branson could learn something from him.
