Stratolaunch completes taxi test at 80 mph

9:21 am

Capitalism in space: Stratolaunch this week completed a series of taxi tests with its giant airplane Roc, reaching speeds as much as 80 mph.

This is a little less than half the speed required for take-off. It also appears that they are proceeding very cautiously with these taxi tests, increasing the speed with each new test by small amounts, about 20 to 40 mph.

The big moment will of course be when this giant plane actually takes off. It appears that might happen within a month or so.

Rocket Lab officially opens new rocket facility

9:15 am

Capitalism in space: Rocket Lab today unveiled a new rocket production facility designed to mass produce its rockets.

The new 7,500 sq/m (80,700 sq/ft) rocket development and production facility in Auckland, is designed for rapid mass production of the Electron rocket. Adding to Rocket Lab’s existing production facility and headquarters in Huntington Beach, California, the new facility brings Rocket Lab’s manufacturing footprint to more than 4.5 acres and enables the company to build an Electron rocket every week.

The new facility was officially opened on 12 October 2018 NZDT, by Rocket Lab Chief Executive Peter Beck and special guest William Shatner, best known for his role as Captain Kirk in the Star Trek series and films.

It suddenly occurred to me that the construction of this facility might explain the long delay in Rocket Lab’s next launch. I suspect they wanted to incorporate any corrections or redesign to the malfunctioning motor controller that was identified just prior to a planned launch in June.

This also suggests that once they complete their next two launches, now scheduled for November and December, they will hit the ground running and will be aiming for frequent launches, maybe as many as once per week.

Updates on yesterday’s Soyuz failure

8:49 am

The Russian investigation into yesterday’s Soyuz launch failure has tentatively identified a malfunctioning valve as a possible source of the failure.

“The state commission has tentatively established a malfunction of the fuel dump valve of the rocket’s oxidizer tank:exhaust gas coming from the valve pushes a side section away from the center section. The valve appeared to be defective and failed to function,” the source said.

The valve passed the preflight check, he said. “It was opened before the launch, and closed afterwards consistent with the procedure,” the source said.

Once the rocket is fueled, the valve dumps redundant oxygen. “It is closed several minutes before the launch. It is supposed to open after the side section separates from the central section, but that did not happen,” the source said.

The “side section” refers to the Soyuz’s strap-on boosters. The “central section” refers to its core stage. From this report it appears the failure of the valve has been linked to a collision between the stages at separation.

“There are no final versions but the primary cause is understandable and is related to the collision of a side element making part of the first stage. A collision occurred during the separation of the first and second stages,” the Roscosmos official said.

“A deviation from the standard trajectory occurred and apparently the lower part of the second stage disintegrated. The rocket stopped its normal flight and after that the automatic system did its work,” Krikalyov said.

An element of the booster’s first stage collided with the second stage, Krikalyov said. “This could have been caused by the failure of the system of the normal separation, which should have been activated. We will analyze the causes in detail,” the Roscosmos official said.

This is obviously only a preliminary result, and should be treated with caution. Meanwhile, the investigation has also launched a criminal investigation. This doesn’t surprise me, as the Russians will sometimes consider some things, such as incompetence, as falling under criminal statutes. Considering the discovery of a drilled hole on a launched Soyuz capsule only a few weeks ago, however, I think they are probably even more paranoid than normal.

Update: Russia has decided they will launch a unmanned Soyuz mission before resuming manned flights.

This is definitely going to impact ISS operations, and cancels a December manned Soyuz launch.

The Soyuz capsules attached to ISS have a 200 day lifespan in space. Thus, the crews on board cannot stay past those dates, which means if launches get delayed for a significant period the station might end up without a crew. NASA has said ISS can be operated in this manner, but I also know they want to avoid this if at all possible.

MASCOT’s journey on Ryugu

MASCOT's journey on Ryugu

MASCOT’s German science team has released a summary of the lander/hopper’s results and seventeen hour journey across the surface of the asteroid Ryugu. The image on the right, reduced and cropped to post here, shows the spacecraft approach, landing, and numerous hops across the surface. If you click on the image you can see the full high resolution image.

Having reconstructed the events that took place on asteroid Ryugu, the scientists are now busy analysing the first results from the acquired data and images. “What we saw from a distance already gave us an idea of what it might look like on the surface,” reports Ralf Jaumann from the DLR Institute of Planetary Research and scientific director of the MASCOT mission. “In fact, it is even crazier on the surface than expected. Everything is covered in rough blocks and strewn with boulders. How compact these blocks are and what they are composed of, we still do not know. But what was most surprising was that large accumulations of fine material are nowhere to be found – and we did not expect that. We have to investigate this in the next few weeks, because the cosmic weathering would actually have had to produce fine material,” continues Jaumann.

The spacecraft apparently bounced eight times after first contact, then executed three hops. The rubble pile nature that is observed I think explains why the Hayabusa-2 science team decided to delay its own landing for a few months so they could figure out a plan. It really appears that Ryugu does not have any smooth flat spots, as expect.

Zimmerman op-ed: Bring on more Kavanaughs!

12:24 am

Today the website American Greatness posted an op-ed by yours truly, entitled Bring on More Kavanaughs! Key quote:

Now is the time to look these bullies in the eyes, and tell them that we will not be intimidated, that we will stand for what we believe, and we will not bow to their smears and slanders and screaming protesters who know nothing of us, care nothing for us, and are increasingly willing to harm us and our children because we reject their oppressive and overbearing demands.

Check it out. It has nothing to do with space, but everything to do with having and keeping a civilization that can make the exploration of space possible.

Astronomers double the number of known fast radio bursts

9:31 am

Using a radio telescope in Australia astronomers have now doubled the number of known fast radio bursts.

Fast radio bursts come from all over the sky and last for just milliseconds. Scientists don’t know what causes them but it must involve incredible energy—equivalent to the amount released by the Sun in 80 years.

“We’ve found 20 fast radio bursts in a year, almost doubling the number detected worldwide since they were discovered in 2007,” said lead author Dr Ryan Shannon, from Swinburne University of Technology and the OzGrav ARC Centre of Excellence.

In other words, only forty bursts total have ever been detected. The data here however suggests that the bursts are coming from very far away and from the early universe, information which will help scientists figure out what is causing them.

Hayabusa-2 landing on Ryugu delayed until January

9:22 am

Because of the roughness of the surface of Ryugu, the Hayabusa-2 science team has decided to delay the landing of the spacecraft on the asteroid from the end of this month until late January at the earliest.

JAXA project manager Yuichi Tsuda said they needed more time to prepare the landing as the latest data showed the asteroid surface was more rugged than expected.

“The mission … is to land without hitting rocks,” Tsuda said, adding this was a “most difficult” operation. “We had expected the surface would be smooth … but it seems there’s no flat area.”

.

This decision is a wise one. They will have the ability to land very precisely, and this will give them time to find the least risky spot. It does indicate however that the landing itself is going to be risky, which is probably why they want more time to gather data beforehand. Should the landing fail, the mission will essentially be over. This way they can maximize what they learn.

Blue Origin delays New Shepard and New Glenn

9:15 am

Capitalism in space: Blue Origin announced yesterday that they are delaying the first manned test flights of their suborbital New Shepard spacecraft until next year.

The announcement also outlined their planned test launch schedule for their orbital New Glenn rocket, now set to launch for the first time in 2021, delayed from 2020 as previously announced.

I find it interesting that the same day the Air Force announces that it is giving this company a half billion dollars for development of this rocket, the company reveals that it is delaying the launch for one year. To my mind, the extra money should have helped them keep their schedule, instead of causing a delay.

What instead happens in Washington, however, is that the subsidized companies now stretch out their program in order to get more government money, focused more on that cash then on building anything. Witness for example Boeing and SLS.

What makes this strange is that Blue Origin already has plenty of capital, to the tune of about a billion per year, from Jeff Bezos. His investment should really be plenty for this company to do what it needs to do.

Audit of SLS predicts more cost overruns and delays

9:03 am

Ever get a feeling of deja vu? A report by NASA’s inspector general yesterday slammed NASA and Boeing for their management of the SLS program, noting that the first unmanned launch will likely be delayed further and the cost for the program will go up another $4 billion.

The much-anticipated premiere of NASA’s Space Launch System rocket will likely see yet another push to the right, this time beyond mid-2020, as the program faces billions in cost overruns, according to a scathing audit released Wednesday by the agency’s Office of Inspector General.

Originally slated to launch from Kennedy Space Center’s pad 39B in December 2017, a 322-foot-tall version of the rocket known as SLS Block 1 will likely still be unprepared for a liftoff on the uncrewed Exploration Mission-1 by June 2020, auditors said. Even if teams could technically meet that deadline, NASA would need to offer Boeing, the contractor building the first two core stages, an infusion of $1.2 billion: $800 million to secure first stage delivery to KSC by December 2019 and an additional $400 million to make sure EM-1 launches by June 2020.

“Consequently, in light of the Project’s development delays, we have concluded NASA will be unable to meet its EM-1 launch window currently scheduled between December 2019 and June 2020,” a portion of the 50-page report reads.

The report [pdf] states that Boeing’s budget will have to double to $8 billion to meet these demands. In truth, SLS has cost the taxpayers a lot more than that, probably in the range in excess of $30 billion, if you add up all the yearly appropriations from Congress specifically applied to this rocket project and extend them through the first manned launch, now probably not taking place prior to 2024. (See my policy paper, Capitalism in Space, to see the breakdown.)

If this audit is correct, and I see no reason not to believe it, it will have taken the modern NASA more than twenty years to build and launch a single manned capsule, with a total cost of over $60 billion.

SpaceX built Falcon 1, Falcon 9, Falcon Heavy, Dragon cargo, and Dragon manned in about half that time, for a cost of about $2 billion. Falcon Heavy alone cost $500 million, and took only seven years.

From whom would you buy the product?

Soyuz upper stage fails, forces emergency landing of manned capsule

8:28 am

During a manned Soyuz launch today the rocket’s upper stage failed, forcing an emergency landing of the Soyuz capsule.

A normally reliable Soyuz FG rocket malfunctioned two minutes after liftoff from Kazakhstan Thursday, forcing a Russian cosmonaut and his NASA crewmate to execute an emergency abort and a steep-but-safe return to Earth a few hundred miles from the launch site. Russian recovery crews reported the crew came through the ordeal in good shape. “NASA astronaut Nick Hague and Russian cosmonaut Alexey Ovchinin are in good condition following today’s aborted launch,” NASA Administrator Jim Bridenstine tweeted from Kazakhstan.

…two minutes and two seconds after liftoff, just a few seconds after the rocket’s four liquid-fueled strap-on boosters separated from the central core stage, something went wrong. Long-range tracking cameras showed the strap-ons and what appeared to be multiple other objects falling away from the rocket.

“Failure of the booster,” a translator called out, presumably relaying a report from Ovchinin to Russian mission control near Moscow. “Failure of the booster.” Moments later, he confirmed the Soyuz had separated from the rocket’s upper stage, saying “we are in weightlessness.”

During their descent they experienced g-loads as high as about 7 g’s, which is high but not unprecedented or even close to a record.

The quote above calls the Soyuz “normally reliable.” That description applied up until about a decade ago. In the past decade there have been several failures of that rocket, though all previous failures occurred with an unmanned payload.

With this failure the need to get the American commercial capsules operational has become very urgent, since we now have no way to get humans up to ISS. The astronauts on board ISS have Soyuz capsules for return, but no one can come up to replace them.

For example, one of the reasons cited for delaying the first SpaceX unmanned test flight from December into 2019 was scheduling difficulties at ISS. This might change now and allow an earlier flight.

I have embedded video of the launch below the fold.
