Some results from SpaceX’s Dragon launchpad abort test

10:17 am

SpaceX has revealed some of the results from their Dragon launchpad abort test in May, which may explain why they have delayed the launch abort test until next year.

SpaceX engineers are evaluating the results of the May 6 pad abort test, in which the prototype Crew Dragon rocketed away from Cape Canaveral’s Complex 40 launch pad, reached an altitude of nearly one mile, and splashed down under parachutes just offshore in the Atlantic Ocean. Officials said data from the test showed a slight underperformance of the SuperDraco jetpack, and capsule did not reach the top speed and altitude targeted by engineers. But the test was successful by NASA’s standards, and the space agency awarded SpaceX a $30 million milestone payment after data reviews. [emphasis mine]

The article says that the delay is to make sure they are doing a launch abort test with the capsule design they intend to use, rather than an earlier design. I wonder if they also have decided they need more time to tweak their designs after this first test, and thus don’t want to use the capsule they had original planned to use since it has an older design.

Instead, the plan is to use the actual capsule after it has flown to ISS in their unmanned demo test flight of the manned capsule. They will not only be using their in-flight design for the test, this will give them extra time to study the results from the first test and revise the SuperDraco engines.

Musk makes first extended public comments since Falcon 9 failure

11:43 pm

In the heat of competition: Elon Musk on Tuesday made his first detailed public comments about the Falcon 9 accident, the on-going investigation, and the aftermath.

Musk hopes to release more details on the failure by the end of this week after further data analysis and engineering reviews. “At this point, the only thing that’s really clear was there was some kind of over-pressure event in the upper stage liquid oxygen tank, but the exact cause and sequence of events, there’s still no clear theory that fits with all the data,” Musk said. “So we have to determine if some of the data is a measurement error of some kind, or if there’s actually a theory that matches what appear to be conflicting data points.”

He also had no word on when launches would resume.

Dragon/Falcon 9 launch abort test moved from Vandenberg to Kennedy

8:50 am

Instead of using the Air Force’s Vandenberg launch complex in California, NASA and SpaceX have shifted their plans for the final launch abort test of the manned version of Dragon capsule to the Kennedy Space Center in Florida.

The date for the test has not been finalized, but it appears it will be delayed until after the next Dragon flight to ISS, itself delayed following the Falcon 9 failure on Sunday. The test will also be delayed until after the completion of the unmanned demo flight to ISS of the manned version of Dragon. SpaceX will then refurbish that demo capsule and re-use it for the launch abort test.

Update: I have rewritten the paragraph above, correcting my first version, which had mistakenly said that a refurbished cargo version of Dragon would be used for the launch abort test. My very knowledgeable readers noted the error and set me straight.

The negative, depressing mainstream press

10:08 am

Sunday’s Falcon 9 failure has given us a great opportunity to learn something about the mainstream press and the elite culture that dominates it. As expected, while the space-oriented press focused on what happened and what will be done to fix the problem, almost every mainstream press outlet immediately concluded that the failure was a disaster that could and (with some outlets) should ring the death knell for private space. Here are just a few examples:

I could go on. Notice that these are almost all mainstream news sources. The few that specialize in science reporting, such as Scientific American, New Scientist, and National Geographic, also tend to push the left wing science agenda.

If you can force yourself to read these articles, as I have, you will find yourself inundated with negativity, pessimism, and a can’t-do attitude. Moreover, many of these articles seem expressly designed to encourage the public and politicians to withdraw their support for space exploration. For example, the Scientific American article, in outlining the history of recent ISS cargo failures, includes this quote:

Public support for the private space industry also took a blow last October (just three days after the Orbital Sciences ATK mishap) when Virgin Galactic’s suborbital space plane SpaceShipTwo crashed during a test flight, killing one of its pilots. [emphasis mine]

Does Scientific American provide us any evidence that public support had dropped after these failures? No. In fact, there is absolutely no evidence that support dropped, and if anything, based on the budget increases over the years for commercial space (despite Congressional efforts to trim that budget), support has continued to grow through thick and thin.

No, Scientific American inserted this statement because they want support to drop, and have tailored their article to help make that a self-fulfilling prophecy. The negativity of all these other articles suggest that their writers and outlets feel the same. Life is hard! Bad things can happen! Better that we stick our head in the sand and hide from the evil thunder gods rather than look up to try to figure out what thunder is!

For myself, I do not find the Falcon 9 failure this past weekend depressing in the slightest. This is a company and a rocket that hadn’t even existed a little more than decade ago, and in that short time they have revolutionized the rocket industry. Rockets fail. This is no surprise. Their track record, however, tells us that they will figure out what went wrong and start flying again, as soon as they can.

What I do find depressing is the failure culture of today’s modern intellectual society. It is one reason I do not depend on them for news, and in general try to depend on them for as little as possible for anything else.

Falcon 9 explodes two minutes into launch

9:43 am

Today’s Falcon 9 rocket launch of a Dragon freighter to ISS ended in failure slightly past 2 minutes after lift-off when the upper stage exploded.

My first thought about this failure is the supply problems it causes at ISS. The Progress failure in April strained the supply lines, making this Dragon flight somewhat critical.

In a presentation to a committee of the NASA Advisory Council here April 9, NASA officials said that food supplies on the ISS would reach a threshold called “reserve level” on July 24, and go to zero by Sept. 5. That assumed that the station received no more supplies beyond a SpaceX Dragon cargo mission launched to the station in April.

The other major limiting consumable is a solid waste container known by the Russian acronym KTO. Without additional cargo missions beyond the Dragon flight, KTO supplies would reach the reserve level July 20 and be exhausted on Sept. 2. Other consumables, including water, would not reach reserve levels until later in the year or early 2016.

In other words, some of the station’s toilets are going to begin to overflow without more supplies. It is possible however that this problem will be alleviated by the planned July 3 launch of the next Progress, especially since NASA officials claimed just prior to the launch failure today that ISS had enough supplies to last through October.

As for the launch failure, I expect that SpaceX will quickly pinpoint the problem and schedule another launch. I have embedded video of the launch below the fold. Prior to the explosion of the first stage all looks completely normal. In fact, immediately before the failure the announcer notes this fact, making what happens next especially shocking.

Update: I have corrected the first paragraph, correcting it from “first stage” to “upper stage.”

The world launch market embraces launch reusability

9:43 am

The competition heats up: After years of resistance, rocket companies the world over are now shifting to the holy grail of reusability, pressured by the effort of SpaceX to land its first stage vertically and recover it.

While the article gives a nice overview of the efforts of ULA and Airbus to recover the engines from their first stage, its summary of SpaceX’s effort is especially complete, and is excellent background for anyone interested in that company’s next recovery attempt, set for Sunday’s Dragon launch.

Falcon 9 landing barge replaced and upgraded

9:27 am

The competition heats up: SpaceX has replaced one of its automated first stage landing barges with an upgraded version.

With dimensions virtually identical to Marmac 300, she carries some new features, including a steel blast wall erected between the rear containers and the landing deck, in addition to the steel bow wall as previously seen on Marmac 300. Ongoing work visible on deck suggests that a second blast wall may be installed at the forward end of the landing deck as well.

The article also provides us a nice contrast between the government and the private sector. While a private company is now willing to buy a flight with a recovered first stage, even before a successful landing, the government is far more cautious:

According to Mr. Musk, officials have asked for “repeated, successful” demonstrations of a first stage landing on the drone ship before a landing attempt will be allowed at the Cape.

That the company has already demonstrated twice that the first stage can return very precisely to its target should have already satisfied these officials. Moreover, the landing site would be well secured and maintained by SpaceX, and they appear quite willing to bear any repair costs should the stage crash on that landing site.

SES wants to launch with a recovered Falcon 9 first stage

10:31 pm

The competition heats up: Commercial satellite company SES has requested SpaceX that one of its satellites be the first to be launched with a recovered Falcon 9 first stage.

SES has seven satellites under construction, five of which are contracted for SpaceX launches, starting with SES-9. SES said it has been given a guarantee by SpaceX that the launch will occur no later than September. SES has agreed to allow SES-9 to be the first launch using an upgraded Falcon 9 main-stage Merlin 1D engine, whose performance is being increased to allow SpaceX to attempt first-stage recovery even on launches to geostationary transfer orbit, the destination of most telecommunications satellites.

Just as it secured an attractive SpaceX price for the SES-8 by being one of the first established customers, SES now wants a cut-rate price on a Falcon 9 with a previously used first stage. “Our launch vehicle for SES-9 will be a recoverable vehicle,” Halliwell said. “We believe they will be able to recover it on this mission. We actually asked them: If we do recover it, can we use it again and get a good price discount? We’re still in discussions.”

In other words, if SpaceX is successful in landing the first stage after it puts SES-9 into orbit in September, they want first dibs, at a good price, of using that stage on a future SES launch.

SES’s willingness to do this changes my estimated time frame for the first successful reuse of a first stage. I had assumed that the commercial satellite companies would all be reluctant to put one of their payloads on a rocket using a recovered first stage, until they had seen at least one test flight of such a stage. SES proves this assumption wrong, to my delight.

SpaceX – The Blue Danube

6:01 pm

An evening pause: This SpaceX video taken by a camera attached to the fairing of the Falcon 9 rocket is cool not because of the video itself. Cameras on rockets have become routine, even for NASA. What is cool is that they have unveiled it using the same Johann Strauss waltz used in the move 2001: A Space Odyssey (1968). It shows that SpaceX is aware of the cultural impact of what they do.

Hat tip Tom Wilson, Tom Biggar, and others.

SpaceX begins planning a 4,000 satellite internet constellation

9:46 am

The competition heats up: SpaceX has filed papers with the FCC to begin testing the design and construction and launch of a constellation of 4,000 satellites for providing global internet access.

Musk’s FCC filing proposes tests starting next year. If all goes well, the service could be up and running in about five years. The satellites would be deployed from one of SpaceX’s rockets, the Falcon 9. Once in orbit, the satellites would connect to ground stations at three West Coast facilities. The purpose of the tests is to see whether the antenna technology used on the satellites will be able to deliver high-speed Internet to the ground without hiccups.

It appears to me that Musk’s constellation will be made up of cubesats, small and cheap to build, and easy to launch in large numbers as secondary payloads on every Falcon 9 launch. In other words, as long as SpaceX can get customers to pay for launches of large satellites on its Falcon 9, Musk will be able to launch and maintain his constellation of cubesats for free.

Problems at Stratolaunch

10:29 am

In the heat of competition: Stratolaunch and Orbital ATK have quietly parted ways as problems have developed in building Stratolaunch’s giant first stage aircraft.

The company went with a radical engineering idea — using a giant airplane as their first stage — which might turn out great but could just as easily become a disaster and failure. Such ideas are by their nature filled with many unknowns.

In a sense, this story validates SpaceX’s approach to developing new space technology, which is to take known engineering and to upgrade it while refining the production methods for building it to lower costs. With this approach, you lower risks by reducing the number of unknowns you have to deal with.

Airbus unveils its first stage re-useability concept

2:32 pm

The competition heats up: Airbus unveiled today its prototype design to recover and reuse the engines and avionics of its Ariane rockets.

Herve Gilibert, technical director for Airbus’ Space Systems division, said the Adeline propulsion unit — engine and avionics — is where lies most of the value of the first stage. The Airbus team concluded that SpaceX’s design of returning the full stage to Earth could be simplified by separating the propulsion bay from the rest of the stage, protecting the motor on reentry and, using the winglets and turbofans, return horizontally to a conventional air strip. “We are using an aerodynamic shield so that the motor is not subjected to such high stress on reentry,” Gilibert said. “We need very little fuel for the turbofans and the performance penalty we pay for the Ariane 6 launcher is far less than the 30 percent or more performance penalty that SpaceX pays for the reusable Falcon 9 first stage.

Gee, for decades Arianespace and Boeing and Lockheed Martin and everyone else in the launch industry insisted it made no economic sense to try to recover and reuse the first stage of their rockets. Then SpaceX comes along and makes an effort to do so, without as yet even coming close, and suddenly everyone agrees it is economically essential to do it as well.

Isn’t competition wonderful?

Air Force asks private companies to develop new rocket engines

5:47 pm

The competition heats up: The Air Force has issued a request for proposals for the development of new rocket engines to replace the Russian engine used on the Atlas 5 rocket.

The press release is a little vague in that it seems to be calling for the development of this new engine, but it could also be interpreted as calling for the development of an entire rocket system. The amount of money involved is too small for this, however, so I suspect we are only talking about engine development here.

Meanwhile, they will continue to issue launch contracts to ULA and SpaceX while they wait for this new engine to be developed. Note also that this sure is a good deal for ULA, getting the Air Force to pay for upgrades to its Atlas 5 rocket.

ESA and Airbus Safran agree on deal to build Ariane 6

4:56 pm

The competition heats up: Airbus Safran have come to an agreement with the European Space Agency on building Ariane 6, Europe’s next commercial rocket.

The key part of the deal is that ESA and Arianespace will be ceding ownership of the rocket to Airbus Safran.

The French government is likely to approve the sale of CNES’s 34-percent stake in the Evry, France-based Arianespace launch service provider to Airbus Safran Launchers at about the same time as the Ariane 6 development contract is signed.

With that sale, Airbus Safran will control Arianespace, which means they will also own the rocket they are building for Arianespace. This is fundamentally different than the situation with Ariane 5, which Airbus built for an Arianespace owned and run by the many-headed ESA. The result was a bloated government-run operation that never made a profit.

Now Airbus will own it instead. They have already indicated that they will trim the costs at Arianespace. More importantly, with ownership will come the freedom to compete effectively in the much more competitive launch market created by the arrival of SpaceX. No need to get permission from ESA to do things.

Russian executive acknowledges SpaceX is beating them

9:03 am

The competition heats up: The chief executive of one of Russia’s largest aerospace centers admitted during a television appearance on Friday that their country is losing market share to SpaceX.

“The commercial launch market has changed over the past few years. New players have emerged, for example the American company SpaceX. Few people believed that a commercial project would be able to break into the market and create a competitive product, create a carrier [rocket] that’s competitive in terms of price and quality. But this has happened and we have to reckon with it,” he said. “It’s true that we have reduced our presence in the commercial launch market in recent years.

The irony here is that all of the decisions by Putin and the Russian government since SpaceX’s arrival — most especially the decision to consolidate the entire aerospace industry into a single corporation controlled by the government — have actually worked to limit Russia’s ability to compete.

Arianespace admits it is in a head-to-head competition with SpaceX

9:21 am

In testimony at a hearing in the French parliament the head of Arianespace admitted that the company has been in a head-to-head competition with SpaceX for the past two years, with SpaceX grabbing half the business.

He also claimed that they think they will be able to compete with SpaceX, even if it succeeds in recovering and reusing its first stage.

Israel said Arianespace fully expects SpaceX to succeed in its attempt to recover its Falcon 9 first stage.

But that’s just the start of the challenge, he said. It remains unknown what the refurbishment costs will be compared to the cost of churning out a fresh stage from an existing production line. He said it is also unclear whether commercial fleet operators will immediately accept placing $200 million telecommunications satellites on a rocket with a refurbished stage.

Finally, he said, flying a reusable stage means sacrificing first-stage performance so that enough energy is available to power it back to its recovery point. That power is thus unavailable for the mission, which is one reason why Hawthorne, California-based SpaceX thus far has attempted to recover its stages only on low-orbit missions, not for missions to geostationary transfer orbit, where most commercial satellites operate.

All true, but if Arianespace sits on its hands because of these facts it will eventually lose. It needs to rise to the challenge that SpaceX poses, not poo-poo the challenge.

Construction at SpaceX’s new spaceport about to begin

9:23 am

The competition heats up: SpaceX has begun prepping the construction sites at its private spaceport in Brownsville, Texas.

The county has begun work on a road to where the spaceport command center will be, and SpaceX has established its construction headquarters in a double-wide trailer there. It is expected that actual construction of the command center will begin in August, with the launchpad construction to follow.

The expected cost for building the entire spaceport: $100 million. Compare that to the billions the Russians are spending for Vostochny, or the billions that NASA spends on comparable facilities.

Dragon launchpad abort test a success

8:27 am

The competition heats up: SpaceX’s first abort test of its Dragon capsule was completed successfully this morning.

The test not only demonstrated the capsule’s ability to escape the launchpad and land safely in the ocean nearby, it proved that its SuperDraco thrusters have the power to lift the spacecraft off the pad, which also means they have the power to lower the capsule to a soft landing on land.

Video embedded below.

Next Falcon 9 launch set for Monday

8:56 am

The competition heats up: The next commercial Falcon 9 launch is now set for tonight, Monday, less than two weeks after the last Falcon 9 launch.

The next two weeks will be especially busy for SpaceX, as they also have scheduled the first launch abort test of Dragon on May 5. The launch will also be the fifth for Falcon 9 this year, putting it in the lead as the busiest rocket in the world for 2015, ahead of the Russian Soyuz.

NASA ISS cargo contracts delayed

8:15 am

The competition heats up: NASA has delayed, for the second time, when it will award its next round of cargo contracts to ISS, pushing the date back from June to September.

Though agency officials said they could not reveal why they had delayed the contract awards, they did say it was to gather more information. My guess is that the agency wants to see how SpaceX’s launch abort tests turn out this year before it makes a decision. If successful, they will then have the option of dropping SpaceX’s as a cargo carrier and pick someone else, possibly Dream Chaser, to provide up and down service to ISS. That way, they would increase the number of vehicles capable of bringing people and supplies up to ISS.

Delaying the award decision until September gives them time to evaluate the abort tests results, as well as give them a cushion in case those tests get delayed somewhat.
