NASA officially approves SpaceX’s fueling system

9:08 pm

Surprise, surprise! NASA on August 17 officially approved SpaceX’s fueling system where the astronauts would enter the Dragon capsule before the Falcon 9 rocket would fueled.

In a statement published late Aug. 17, the agency said that it was allowing SpaceX to move ahead with plans to use what’s colloquially known as “load-and-go,” where the Falcon 9 launch vehicle is filled with liquid oxygen and kerosene propellants after astronauts board the Crew Dragon spacecraft on top of the rocket.

“To make this decision, our teams conducted an extensive review of the SpaceX ground operations, launch vehicle design, escape systems and operational history,” Kathy Lueders, NASA’s commercial crew program manager, said in the statement. “Safety for our personnel was the driver for this analysis, and the team’s assessment was that this plan presents the least risk.”

Blah, blah, blah. They had made it clear they were going to approve SpaceX’s fueling approach last week. NASA safety bureaucrats have been whining about SpaceX’s fueling approach for more than a year and a half, for no logical reason, and for what I surmised were purely political reasons having zero to do with safety. At times I have stated that when SpaceX was getting close to actually flying, NASA would back down. And I also expected SpaceX to push its launch dates to force NASA to back down, in contrast to the old-time big space contractors who routinely would kowtow to NASA in these matters and allow its bureaucracy to push them around.

These events are more evidence that the April 2019 manned Dragon launch is on schedule.

SpaceX unveils access arm jetway astronauts will use to board Dragon

2:04 pm

Capitalism in space: SpaceX has begun installing its airport-jetway-like access arm that astronauts will use to board Dragon at Launchpad 39A in anticipation of the first manned flight in April 2019.

They were originally going to install the jetway after the first unmanned demo flight, which they hoped to fly this month. That plan has now changed.

Prior to the visual milestone this week of the Crew Access Arm, or CAA, being moved to the pad surface and the base of the Fixed Service Structure (launch tower), previous information from SpaceX and NASA indicated that the arm would be installed after the Dragon’s uncrewed demo flight.

However, that schedule was based around a launch of the uncrewed Dragon flight, DM-1, in August 2018.

With NASA announcing a 3-month slip to the DM-1 flight (largely due to ISS scheduling and crew reduction aboard the International Space Station in the coming months), SpaceX found itself with an unanticipated delay to the DM-1 flight – which in turn opened up a possibility that didn’t exist before to install the CAA in August.

…But now that DM-1 is NET (No Earlier Than) November – a date Gwynne Shotwell is confident the company will meet, SpaceX is forging ahead with CAA installation because, quite simply, there is no reason to wait, at this point, to install the arm after DM-1.

Making the crew access arm resemble an airport jetway is a fine example of the pizazz that helps sell SpaceX. It also helps make space operations appear more like an ordinary transportation option, something that is necessary if the human race is ever going to become truly spacefaring.

Will SpaceX bail out Tesla?

10:13 am

Link here. There appears to an effort on Wall Street to convince SpaceX to use its significant profits to bail out failing Tesla. It is also unclear whether Musk agrees with this approach.

If SpaceX does this, it will be a very bad thing for the company’s future, throwing good money after bad. Musk might love both companies and what they are trying to accomplish, but the future of the two companies appears to be heading in opposite directions. To weigh SpaceX down with an unprofitable company that has a failing product would seriously harm SpaceX’s abilities in the future.

SpaceX unveils interior of manned Dragon

10:02 am

Capitalism in space: Earlier this week SpaceX unveiled the interior of its Dragon capsule, along with the suits and other details, to reporters in California.

The article at the link has some good videos showing the capsule interior as well as its touchscreen control panel. It also includes quotes from SpaceX’s president Gwynne Shotwell repeating their intention to launch the manned mission by April 2019.

“Whenever we talk about dates we’re always confident and then something crops up,” Shotwell said. “Predicting launch dates can make a liar out of the best of us. I hope I am not proven to be a liar on this one. We are targeting November for Demo 1 and April for Demo 2.”

“I would love to say that this mission is going to be like every other mission, because I want every rocket and every capsule to be reliable, but I can tell you there will be about 7000 extra sets of eyes on the build of this system, the testing of this system and all the interfaces,” Shotwell added.

I would not be surprised if there was a few months slip in that schedule. I will be surprised if it slips more than that.

The two things SpaceX must do for NASA to okay the first manned Dragon mission

10:08 am

Link here.

First, they must successfully recover the Dragon capsule from the first unmanned test flight in November so that they can use it in a launch abort test to follow.

Second, they must demonstrate seven successful flights of the Block 5 version of the Falcon 9 rocket.

Right now it appears that, though the schedule is very very tight, it is possible that SpaceX will be able to accomplish these tasks in time to do its manned flight in April 2019, as presently scheduled. At the moment SpaceX’s launch schedule calls for 11 Falcon 9 launches between now and April. Getting seven Block 5 launches should therefore be likely, though not certain, since some of those launches will probably not use the final full Block 5 configuration.

I notice that the article makes no mention of the massive paperwork that the GAO says must be done before a manned flight. No surprise. In the end the paperwork will not delay this mission, despite what the GAO and NASA’s bureaucracy says.

UPDATE: NASA has now withdrawn its objections to SpaceX’s fueling plans. This is also no surprise, as their objections to fueling the rocket while astronauts were on board were always bogus. The risks are essentially the same whether you fuel before boarding or after. Either way, there is a lot of very explosive fuel present. To say NASA’s way, fueling first, is the only way never made sense.

The history of SpaceX’s Big Falcon Rocket

9:42 am

Link here. This is a ten part very detailed history, and includes a great deal of background into the history of SpaceX as well. Very much worth reading.

In the end, I remain skeptical that this rocket will end up being built as SpaceX presently envisions it. I also believe however that out of this engineering research will come a new rocket that is nonetheless revolutionary.

SpaceX launches commercial satellite with first used Block 5 first stage

8:34 am

Capitalism in space: Last night SpaceX successfully placed a commercial communications satellite into orbit using a previously flown Block 5 first stage.

The turnaround for this first stage was only a little over two months. It successfully landed on the drone ship in the Atlantic, and they plan to fly it a third time later this year. You can watch the launch here.

The leaders in the 2018 launch race:

22 China
15 SpaceX
8 Russia
5 ULA
4 Japan
4 Europe

China still leads the U.S. 22 to 21 in the national rankings.

NASA announces crews for first commercial manned launches

9:00 am

NASA has announced the crews for the first commercial manned launches.

Boeing’s crew flight test aboard its Starliner spacecraft, which is targeted to launch in mid-2019, will have Eric Boe, Chris Ferguson and Nicole Mann on board. Boeing’s first post-certification mission will have Josh Cassada and Suni Williams aboard.

SpaceX’s demo mission 2 aboard its Crew Dragon spacecraft, which is targeted to launch in April 2019, will have Bob Behnken and Doug Hurley aboard. The first post-certification mission will be crewed by Victor Glover and Mike Hopkins.

These crews cover the first two manned missions for each spacecraft.

New launch dates for commercial crew posted by NASA

2:26 pm

NASA has now released an updated schedule for the first test flights of Boeing’s Starliner and SpaceX’s Dragon manned capsules:

In chronological order:

SpaceX Demo-1 (uncrewed): November 2018
Boeing Orbital Flight Test (uncrewed): late 2018 / early 2019
SpaceX Demo-2 (crewed): April 2019
Boeing Crew Flight Test (crewed): mid-2019

Note once again that this schedule bears no resemblance to the pessimistic schedule put forth by the GAO. That schedule indicated that significant delays could be expected because of NASA’s heavy paperwork requirements.

I fully expect that political needs will force that paperwork to be done much faster than the GAO, or NASA, expects, or even wants. And the increased speed will have little to do with reducing safety.

NASA safety panel reviews commercial crew, tries to justify its paperwork demands

9:35 am

Link here. The article describes the results from the quarterly meeting of NASA’s safety panel, which occurred last week, including its concerns about the recent test problems during a launch abort test of Boeing’s Starliner capsule. It also describes the panel’s general satisfaction at the status of SpaceX’s Dragon capsule.

The article however ends with a long screed by one panel member, explaining that the heavy paperwork requirements they are imposing on the two companies is not really paperwork.

“It needs to be noted by everyone, and we’re especially interested in making sure that all of the external stakeholders realize this, that while the concluding process of certification has sometimes been described as a paper process, that is really just a shorthand clarification and in reality it could not be further from the truth,” noted Dr. McErlean.

In reality, the process is as follows. “In a certified design, the design agent – the contractor or partner in this case – performs the design and in the certification plan, the design agent and the certification agency (NASA) agree on the submittal of certification evidence.

“This could be measurements, it can be test data, it can be analysis, but it almost always involves the submittal of detailed technical data, not simply paper descriptions or forms. Sometimes it involves witness testing and sometimes it involves physical inspection. But it almost always wraps around important technical submittals.

Can I translate? The safety panel requires a lot of testing so that a lot of paperwork can be filled out. And while much of this testing is likely to help make the capsule’s safer, most of it seems to me to be make-work, and designed to justify the existence of NASA and its safety panel.

Watch SpaceX retract one leg from used Block 5 booster

12:42 am

For geeks only! The video below the fold shows the new equipment that SpaceX has developed to retract the open legs of a used Block 5 booster. This video shows them attaching the booster in a secure vertical position, then attaching cables to the base of the first leg which are then used to retract it back into its launch position against the side of the booster. The design is quite clever.

The design also shows how primitive the art of reusable rockets remains. Though SpaceX has clearly succeeded in simplifying and automating this process, it remains slow and complex. In time this will get easier, but right now, this remains state of the art.

First Block 5 1st stage reflight

12:47 am

Capitalism in space: It appears that SpaceX is planning to do its first reflight of a used Block 5 booster on August 4.

This will be SpaceX’s third Falcon 9 Block 5 launch in less than two weeks if the schedule holds. More important than the schedule, perhaps, is the fact that it would appear that SpaceX intends to reuse the first Block 5 booster (B1046) for this particular launch. To lay out the foundation of this claim, it’s known that SpaceX’s CCAFS Pad 40 integration facilities are only capable of fitting one booster and the strongback (transporter/erector/launcher, TEL) at a time, evidenced both by sourced comments and views inside the hangar.

Meanwhile, an unmistakeable Block 5 booster – with black interstage and octaweb coverings – was spotted being transported through Cape Canaveral Air Force Station (CCAFS) earlier this week, just after Falcon 9 B1047 launched (July 21 EDT) and freed up space for another booster inside the horizontal integration facility (HIF) at Pad 40. Given that only one Block 5 booster has been recovered on the East Coast and that B1047 was still out at sea earlier this week, the sooty booster traveling through CCAFS thus has to have been B1046, and it was making a beeline for LC-40.

SpaceX is once again demonstrating why they have taken over the global launch industry. They are proving that they will be able to routinely reuse a relatively small number of first stage boosters, frequently, and cheaply.

CORRECTION: I initially wrote this post under the mistaken impression that the booster being reflown was going to do so after only fourteen days. This was wrong. The booster was flown two months ago, in May.
