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

8:31 am

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.

Israeli private Moon mission delayed by SpaceX

10:08 pm

Because of a launch delay announced by SpaceX, the launch of a private Israeli Moon lander has been delayed from December until early 2019.

SpaceIL said Elon Musk’s SpaceX firm, whose rockets are set to carry the unmanned probe into space, had informed it of “a delay of a number of weeks to the beginning of 2019.”

SpaceIL stressed that the delay was SpaceX’s decision, noting in a statement that tests on their craft, shaped like a pod and weighing some 585 kilograms (1,300 pounds), were proceeding successfully.

As a secondary payload, the SpaceIL mission is at the mercy of SpaceX’s primary mission. It is unclear why SpaceX delayed the launch.

Why Modern Music Is Awful

6:01 pm

An evening pause: I find it interesting that almost all of the pop stars mentioned in this video have never been posted here as an evening pause. I want and like variety, and the main take-away from this video is the increasing sameness of modern music. Blah.

In sense, this video is an instruction manual for everyone who wants to send me a suggestion for an evening pause. It tells you the kind of music I will likely not be interested in, should you suggest it to me. To put it simply, if it sounds like everything else produced today, then it won’t get cast in the audition.

Betty Grissom, widow of Mercury astronaut Gus Grissom, passes away

3:00 pm

R.I.P. Betty Grissom, the widow of Mercury astronaut Gus Grissom, who died in the Apollo 1 launchpad fire in 1967, passed away today at 91 after a sudden illness.

The article makes a big deal about her successful lawsuit against North American Rockwell, the manufacturer of the Apollo capsule. I think we should instead emphasize her own courage, allowing her to agree and support her husband as he risked and lost all to help the United States win the race to the Moon.

Air Force awards contracts to ULA, Northrop Grumman, Blue Origin

2:54 pm

The competition heats up: The Air Force today announced contract awards to ULA, Northrop Grumman, and Blue Origin to help further the development of their new rockets.

The award to Blue Origin will be for development of the New Glenn Launch System. The award to Northrop Grumman Innovation Systems is for development of the OmegA Launch System. The award to United Launch Alliance will be for development of the Vulcan Centaur Launch System.

The Launch Service Agreements will facilitate the development of three domestic launch system prototypes and enable the future competitive selection of two National Security Space launch service providers for future procurements, planned for no earlier than fiscal year 2020.

The press release makes no mention of the amount of money being granted to these companies. Personally, I’d rather the government gave nothing until it actually bought real launch services from these companies, but it can only help the Air Force to have four different launch companies (when you include SpaceX) to draw upon. And the competition will force all four to reduce their costs and be creative.

Update: One of my readers in the comments below provided this link outlining the money granted for each contract, with ULA getting just under $1 billion, Northrop Grumman getting just under $800 million, and Blue Origin getting $500 million. This is not chicken-feed, and is in essence a subsidy for all three companies. The large amounts will act to discourage cost-savings, and in my opinion is a mistake. Whenever government bodies provide these kinds of subsidies prior to the deliver of services, the cost for the services inevitably is higher.

Honeycombs on Mars

2:10 pm

honeycombs on Mars

Cool image time! The image on the right, cropped to post here, came from the October 3, 2018 image release from the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the science team labels “honeycomb shapes in Ismeniae Fossae.” If you click on the image you can see the full picture.

This particular image does not include a caption so don’t ask me how this feature formed, as I really haven’t the faintest theory, and the MRO science team didn’t provide me one.

It is clear that dust has gathered in small dunes within these honeycombs. That provides no help, however, as the larger honeycombs are surrounded on their ridges by complex smaller ridge patterns that remind me vaguely either of rimstone dams in caves, or of the doodles you might draw during a boring class.

In a river bed?

Increasing the mystery is the location of this feature. The image to the right, annotated to indicate where the insert above is located, shows that the honeycombs are formed at the bottom of what looks like a valley or shallow gorge. The full image emphasizes this, as the terrain to the north and south is a flat plateau above that valley.

That the honeycombs only occur in one small area on that valley floor further deepens the mystery. Unfortunately, MRO has not taken a lot of high resolution images of this area, which is located on the rough plateau region that drains down into the lower northern plains at 39.7 degrees north latitude and 39.9 degrees east longitude. MRO’s wide field camera has covered the area thoroughly, however, revealing it to be a very fractured and complex terrain with many criss-crossing ravines generally draining to the north and east into the northern plains. Scattered throughout this area are many other strange features not that dissimilar from the honeycombs, though not yet photographed at high resolution.

I must emphasize that the drainage path is not that clear, and almost seems chaotic, as if the water, instead of flowing downhill toward the plains, mostly seeped downward through the ground in an almost random pattern, dissolving the gorges because these were fracture or fault zones that were easily eroded.

Why these honeycombs should exist still remains baffling. Maybe they are features of a more resistance material, but if so, that still does not explain their strange shapes.

This is where I will leave this. Mars is wonderfully strange. It will be a fascinating experience to walk on its surface and see it up close.

Honoring the Apollo 8 astronauts

1:24 pm

Apollo 8 astronauts Frank Borman, Bill Anders, Jim Lovell

They are still here. Fifty years after becoming the first humans to leave Earth orbit and travel to another world, a mission that NASA believed only had a 50-50 chance of success, the three Apollo 8 astronauts are still with us, hale and hearty despite the passing of many years.

On October 6 the Museum of Science and Technology honored all three men with a magnificent event. The picture on the right was taken during that event, shortly after the three men, Frank Borman, Bill Anders, and Jim Lovell (from left to right) had posed for a typical group shot. It far better reveals their personalities, with Borman looking outward, Anders thoughtful, and Lovell laughing.

Borman and Lovell are ninety years old, while Anders is about to turn eight-five on October 17. Yet, all three remain as sharp as they were in 1968, when they circled the Moon. Only the wear and tear of age and time is slowing them down. It was an honor to see them again and shake their hands. It was also sad, as it was clear that time stops for no one, no matter how deserving. Flying to the Moon on a mission that many thought incredibly risky couldn’t stop them. Time unfortunately will.

We are blessed to still have them. Once again during the dinner presentation they talked of their mission, kidding each other repeatedly about what had happened, and talking about why they went and what they thought the future might hold. Borman was pessimistic about the future of space, but then he remains fixated on the concept of a government program for space. Anders meanwhile was in touch with the rise of private commercial space, and advocated that it is where the future lies.

Lovell was Lovell, as always a space cadet, enthused for the future exploration of space, no matter how we do it.

This event is likely only the beginning. Over the next year there are going to many similar events, celebrating the fiftieth anniversary the 1960s Apollo triumph, right through to the landing in July. To me, however, it will always be Apollo 8 that had the most historical impact. Everything that happened afterward merely reinforced what that flight taught us.

Below the fold are two more pictures from the event.

China plans next Long March 5 launch for January 2019

9:19 am

The new colonial movement: China has begun the assembly of the third Long March 5 rocket for its next launch, now set for January 2019.

The article provides the most detailed information yet released about the failure during the rocket’s second launch:

The cause was determined to be damage to the turbopump on one of the two cryogenic YF-77 first stage engines, prompting a redesign of the structure and test-firing in Xi’an.

This is still somewhat vague, though it does confirm that the rocket engine needed a redesign.

Should this January 2019 launch go well, it will allow China to move forward on all of its ambitious space exploration plans, including the building of its own space station, numerous robotic missions to the Moon and Mars, followed eventually with manned missions to the Moon.

Update on SpaceX’s effort to recover/reuse its rocket fairings

9:13 am

Link here. Key paragraph:

SpaceX recently began seriously attempting to recover Falcon 9 payload fairings, albeit almost exclusively during West Coast launches in order to let Mr. Steven attempt to catch the parasailing halves in the Pacific Ocean. Thus far, SpaceX engineers and technicians have not yet solved the challenging problems, although fairing halves have reportedly landed as few as 50 meters from Mr. Steven’s grasp and at least five have been recovered intact after landing gently on the ocean surface. On the East Coast, Falcon fairings are not nearly as lucky, typically alternating between smashing directly into the ocean and landing gently upon it, depending SpaceX’s need for experimental recovery data.

The article outlines some of the technical issues they have been facing, as well as how pieces of some fairings have been recovered many hundreds of miles away by fishermen.

The article provides some additional details, including information about the likely landing site in Von Kármán crater. It also notes that there are three launches planned at the spaceport prior to the December launch, and that any issue on any of those launches could delay Chang’e-4’s lift-off. .

UAE passes a space law

7:28 am

The new colonial movement: The United Arab Emuirates Cabinet has passed a space law, supposedly designed to encourage the development of their space sector.

I say “supposedly” because of this:

“Although the details of the new law are not yet publicly available, I believe it has tremendous potential and am excited by the UAE’s incorporation of educational guidelines into the legal framework,” said Sunil Thacker, senior partner at the STA law firm.

It is even unclear whether this lawyer has seen the language. He is quoted extensively, raving about the wonders this new law will bring, but states no specifics. In the top-down sheik-run UAE, he has no other choice.

Ceres’s poles have shifted by as much as 36 degrees

10:31 am

A new analysis of Dawn data suggests that the poles of Ceres have wandered by as much as 36 degrees, and the data also adds further support for the existence of a liquid water layer between the dwarf planet’s crust and mantle.

“The most surprising aspect of this paper is to me the observation that the pole of Ceres must have followed an indirect path to its current pole. A multi-step reorientation could mean that the equatorial density anomaly was still evolving during the reorientation, and this could be because the crust and mantle were weakly rotationally coupled, allowing the crust to start reorienting while the mantle would lag behind,” Tricarico said. “If crust and mantle are allowed to shift with respect to one another, that could point to a layer of reduced friction between crust and mantle, and one of the possible mechanisms to reduce friction could be an ancient water ocean beneath the crust.”

In other words, the crust and mantle are not locked together. Imagine a baseball where the ballcover is not tightly held to the inner core, and slides around it. (Boy there are a lot of pitchers who wish they could get a hand on that baseball.) The cause of that looseness on Ceres is possibly because of a liquid layer in-between the crust and the mantle.

Need I note that there are uncertainties here?

Sunspot update September 2018: Minimum!

9:58 am

NOAA yesterday released its monthly update of the solar cycle, covering sunspot activity for September 2018. As I have done every month since this website began in July 2011, I am posting it below, annotated to give it some context.

Sunspot activity on the Sun in September dropped slightly from August. More significantly, the activity continues to match closely the weak activity seen in 2008, when the Sun last went through its last solar minimum. We are unquestionably now in the new minimum, and its arrival in the past few months makes the now-ending solar cycle about one to two years shorter than predicted.

September 2018 sunspot activity

The graph above has been modified to show the predictions of the solar science community. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May 2009 prediction.

As I noted last month, the NOAA graph is now getting very close to its right edge, which ends in December 2019. They will very soon have to update this graph so that it can take us into the next solar cycle.

What that new cycle will bring will be the next mystery. I have been following this cycle now since its unusual beginning, with a solar minimum much much longer and more inactive than any solar scientist had ever expected. We can only guess at the surprises the Sun will give us in the coming decade, especially since the science of solar sunspot activity remains superficial and in its infancy. We do not really understand why the Sun’s activity fluctuates. Nor do we understand why it periodically stops producing sunspots for long periods, resulting in what solar scientists call a grand minimum.

There are some scientists who think another grand minimum is coming. We shall have to wait and see. I certainly am going to follow their upcoming observations, as this work remains one of the great scientific studies humans are presently pursuing.

The central peaks of Copernicus crater

9:41 am

Central peaks of Copernicus Crater

Cool image time! Lunar Reconnaissance Orbiter science team has released a new image of the central peaks of Copernicus Crater, shown on the right cropped and reduced in resolution.

Copernicus (9.62°N, 339.92°E), which is easily seen with a moderately powerful backyard telescope, is one of the best-known craters on the Moon. Despite its age (around 860 million years), it is well preserved with over 4000 meters of relief from floor to rim, and the tallest of its central peaks rises approximately 1300 meters above the crater floor. This image, centered on the central peaks, was captured just after dawn (86° incidence angle) as the Lunar Reconnaissance Orbiter slewed west to a 67°angle.

The image is similar to one taken back in 2012, but has a higher resolution because it was shot from 50 miles elevation instead of 75.

This crater was also the subject of one of the first breath-taking images ever taken of the Moon from lunar orbit, by Lunar Orbiter in November 1966.

The wider view taken by LRO gives some context for the image above. The peaks shown in closeup here are part of the lower right grouping. If you go to the first link above you can zoom in and explore all parts of the full image, and see some quite amazing details, including the large boulders scatter throughout the hollows between the peaks.

Giant ice pinnacles on Europa

9:15 am

In a new paper scientists note that getting the congressionally mandated Europa Clipper safely to the surface of Jupiter’s moon might be threatened by the existence there of forests of giant five-story high ice pinnacles.

Probes have shown that Europa’s ice-bound surface is riven with fractures and ridges, and new work published today in Nature Geosciences suggests any robotic lander could face a nasty surprise, in the form of vast fields of ice spikes, each standing as tall as a semitruck is long.

Such spikes are created on Earth in the frigid tropical peaks of the Andes Mountains, where they are called “pentinentes,” for their resemblance to devout white-clad monks. First described by Charles Darwin, pentinentes are sculpted by the sun in frozen regions that experience no melt; instead, the fixed patterns of light cause the ice to directly vaporize, amplifying minute surface variations that result in small hills and shadowed hollows. These dark hollows absorb more sunlight than the bright peaks around them, vaporizing down further in a feedback loop.

This work is based on computer models, so it has a lot of uncertainty. It also appears to assume that these pentinentes will be widespread across Europa’s equatorial regions, something so unlikely I find it embarrassing that they even imply it. I guarantee Europa’s surface will be more varied than that. If they are designing Europa Clipper properly, it will go into orbit first to scout out the best landing site, and will be able to avoid such hazards.

Competing proposals for military space operations

9:05 am

Turf war! Even as Trump is pushing for a new Space Force, the military bureaucracy is proposing competing proposals for rearranging its space bureaucracy.

Some of the details are a bit in the weeds but the following lays out some of the basics

Griffin and Wilson take very different approaches.

In her memo, Wilson suggests the Space Development Agency should be organized under the existing Space Rapid Capabilities Office and that it should be geographically and organizationally connected to U.S. Space Command. She recommends using “existing structures designed and chartered to acquire capabilities rapidly, rather than establishing new structures.”

Griffin is proposing a new D.C.-based agency with a staff of 112 government personnel that would report to him initially, but eventually would shift to the control of a new assistant secretary of defense for space, an office that would first have to be approved by Congress.

In Wilson’s plan, the Space Development Agency and other acquisition organizations would transition to the new Department of the Space Force. She pointedly pushes back on the idea of having an assistant secretary of defense for space or a Space Development Agency that reports to that office. She argues that such a setup would create additional bureaucracy that would be removed from the operators who use and maintain the equipment.

Griffin, a former NASA administrator, seems more focused in his proposal in transitioning the military towards using private commercial assets rather than building its own, but his apparent love for building his own empire might work against that stated goal.
