The test flight of Falcon 9/Dragon to ISS will almost certainly not launch on May 7.
It appears they need more time to assess the results of the static engine test on Monday.
SpaceX’s static fire test of the Falcon 9 still set for 3 pm today.
I will be discussing this story and the mining of asteroids on The Space Show today, even as this static fire occurs. Don’t forget to tune in.
Update: the static firing appears to have been a success, after an initial abort.
Want to watch the launch of Falcon 9/Dragon? Here’s the low down.
SpaceX and NASA have now set May 7 as the planned launch date for the Dragon test flight to ISS.
SpaceX has delayed the launch of its Dragon test mission to ISS, with the launch now scheduled sometime between May 3 and May 7.
“After reviewing our recent progress, it was clear that we needed more time to finish hardware-in-the-loop testing and properly review and follow up on all data,” SpaceX spokeswoman Kirstin Brost Grantham wrote in an email. “While it is still possible that we could launch on May 3rd, it would be wise to add a few more days of margin in case things take longer than expected. As a result, our launch is likely to be pushed back by one week, pending coordination with NASA.”
There are really only two important stories today concerning space exploration. The story that is getting the most coverage is the big news that the space shuttle Discovery is making its last flight, flying over Washington, DC, as it is delivered to the Smithsonian for permanent display.
Of these stories, only Irene Klotz of Discovery News seems to really get it. This is not an event to celebrate or get excited about. It is the end of an American achievement, brought to a close probably three to five years prematurely so that the United States now cannot even send its own astronauts to its own space station.
The other news, actually far more important, has gotten far less coverage, and includes three different stories all really about the same thing.

ISS’s robot arm has now been moved into position in preparation for the Dragon berthing flight, scheduled for April 30.
The article also gives a nice outline of the entire Falcon 9/Dragon test flight.
Mark your calendar: Decision day for the SpaceX Falcon 9/Dragon test flight on April 30 will be April 16.
Is this good or bad news? Europe has shut down the production line producing their ATV cargo craft for ISS.
Confronted by parts obsolescence and waning political support, the European Space Agency has shut down subsystem production lines for the Automated Transfer Vehicle as member states debate how they will contribute to future international space exploration efforts, according to top spaceflight officials.
ESA has launched three of the five ATVs it agreed to launch, with the remaining two scheduled in 2013 and 2014. What happens after that remains unclear. It seems from the article the European partners don’t seem interested in upgrading the ATV, and instead seem willing to let the as-yet untried U.S. commercial companies carry the load.
Commercial flights by U.S. spacecraft will make up the rest of the lost capacity with the end of the ATV program.
The pressure continues to build on a successful Falcon 9/Dragon flight on April 30.
SpaceX has now set April 30 as the target launch date for its Falcon 9/Dragon capsule test flight to ISS.
Good news: SpaceX’s dress rehearsal countdown and fuel test of the Falcon 9 rocket at Cape Canaveral today was a complete success.
Fingers crossed: Falcon 9 is on the launchpad in Florida, being prepared for a countdown and fuel test tomorrow.
The Dragon/Falcon 9 test flight to ISS has been delayed again, until late April, in order to complete additional software tests.
New dates, March 20 and May 15 respectively, have been set for the ISS launches of SpaceX’s Dragon capsule and the next manned Soyuz capsule.
The launch date for Dragon, however, is far more tentative.
Bill Harward has some details on the cause of the Dragon/Falcon 9 launch delay.
Essentially, nothing seems critical. They found a few minor issues that they felt needed more testing, and are simply making sure these issues are resolved before launch. All in all I find this report very encouraging. Stay tuned.
The Dragon/Falcon 9 test flight is now set for no earlier than late March.
SpaceX has delayed its February 7 launch of Dragon to ISS.
What competition brings: SpaceX outlines its new design goals for Falcon 9 and its Merlin rocket engine.
[U]pcoming upgrades to the engine (Merlin 1D) will provide a vast improvement in performance, reliability and manufacturability – all of which could provide a timely boost to aiding the potential for success for the fully reusable Falcon 9.
Increased reliability: Simplified design by eliminating components and sub-assemblies. Increased fatigue life. Increased chamber and nozzle thermal margins,” noted SpaceX in listing the improvements in work.
Improved Performance: Thrust increased from 95,000 lbf (sea level) to 140,000 lbf (sea level). Added throttle capability for range from 70-100 percent. Currently, it is necessary to shut off two engines during ascent. The Merlin 1D will make it possible to throttle all engines. Structure was removed from the engine to make it lighter.
Improved Manufacturability: Simplified design to use lower cost manufacturing techniques. Reduced touch labor and parts count. Increased in-house production at SpaceX.
That’s just the engine. Most of the article however talks about the company’s effort to make as much of Falcon 9 reusable as possible. Hat tip to Clark Lindsey.
On Thursday, December 15, 2011, NASA management announced what seemed at first glance to be a very boring managerial decision. Future contracts with any aerospace company to launch astronauts to and from the International Space Station (ISS) will follow the same contractual arrangements used by NASA and SpaceX and Orbital Sciences for supplying cargo to the space station.
As boring that sounds, this is probably the most important decision NASA managers have made since the 1960s. Not only will this contractual approach lower the cost and accelerate the speed of developing a new generation of manned spaceships, it will transfer control of space exploration from NASA — an overweight and bloated government agency — to the free and competitive open market.
To me, however, the decision illustrates a number of unexpected consequences, none of which have been noted by anyone in the discussions that followed NASA’s announcement back in mid-December.

NASA has announced a February 7 launch date for SpaceX’s next test flight of Falcon 9 and Dragon to ISS.
They also have approved allowing Dragon to do a test berth with ISS on this flight, assuming the first test approach goes well.
The next test flight of Falcon 9/Dragon has slipped again.
This article notes how an ISS status report that had indicated approval for a merger of the next two Falcon 9 test flights was premature.
From Clark Lindsey: An ISS status report has confirmed that NASA has combined the next two Dragon test flights into one mission.
More commercial space news; SpaceX is expanding its Florida operations in anticipation of a increased launch rate of Falcon 9 and Dragon capsules in the coming years.
The case against SpaceX. From one of the company’s biggest supporters.
Trent Waddington raises many good points, all of which must be considered to have a clear, educated sense of where the future stands for American manned spaceflight. Two quotes:
The goal of SpaceX is human spaceflight, and the greatest repository of knowledge about human spaceflight is NASA. As such, it would appear obvious that getting NASA to help you to fly humans safely is a good idea. The way to do that is with Space Act Agreements. This is what SpaceX did under the COTS program, and later under the CCDev program.. and they got paid for the privilege. As a result, the Dragon spacecraft will soon be fully qualified as safe for human habitation on orbit as it will be berthed to the ISS and have astronauts inside it.
The problem is that NASA is a precocious customer. They know what they want, they think they know even better than you do how to make it, and they feel no guilt about changing their mind halfway through the project. As such, Space Act Agreements just totally grind NASA’s gears. They don’t have enough control. [emphasis in original]
NASA money is like heroin.. once they start taking it, most people find it very hard to stop. There’s a dependence that has grown between NASA and SpaceX, and although it is obviously a love-hate relationship, it’s going to be very hard for SpaceX to let go.. but, inevitably, they must. The current needs of NASA are very different to the long term goals of SpaceX.
And this:
Fundamentally, SpaceX has a shoddy business case which is best described as a house of cards.. that they’re still trying to play poker with.. and there’s dogs at the table, and they’re smoking cigars! Yeah, metaphor.
Read the whole thing. It’s quite good.
Scheduling the next Dragon flight, the first to hopefully berth with ISS.
Presently they are saying early January, though it appears that no one will be surprised if it gets delayed to February.
Clark Lindsey asked an engineer experienced in building reusable spaceships for his take on Elon Musk’s proposal to make Falcon 9 reusable. The answer is fascinating.
Elon Musk’s talk yesterday at the National Press Club revealed several interesting things, about SpaceX’s rocket effort, about the state of the American commercial space industry, and about Elon Musk himself.
First, the company’s rocket design effort. Musk centered his talk on SpaceX’s new effort to make its Falcon 9 rocket completely reusable. Though he produced little specific details, and the moderator at the event asked no questions about it, it seems the engineering centers around these three concepts:

This is not good if true: SpaceX has admitted that in its December 2010 test flight of Falcon 9 there was a problem with its first stage.
During the August meeting, held at the Johnson Space Center in Houston, SpaceX told to the two advisory bodies that there had been an engine anomaly during the most recent Falcon 9 launch, according Charles Daniel, a shuttle and space station safety expert at Herndon, Va.-based Valador Inc., and a member of the ISS Advisory Committee. “There was no explanation or root cause analysis or corrective action for this particular anomaly,” Daniel said Sept. 9 during the public meeting. “This is a relatively troublesome statement not to recognize that a premature engine shutdown was a significant event.”
Rocket shortage: NASA is reconsidering the Delta 2 rocket as a vehicle to launch its unmanned science satellites.
Chris Bergin at NASAspaceflight.com today wrote a report on the four companies NASA is subsidizing to build manned capsules. The status of each company tells us something of whether they can eventually provide the United States with a replacement for the shuttle, and do it soon. Let’s take a look at each.
