Russians say Soyuz sensor was damaged in manufacture

9:04 am

The Russians yesterday revealed that the sensor they have identified as the cause of the October 11 Soyuz launch failure was damaged during manufacture.

Their response:

Skorobogatov said officials are now taking steps, including putting all assembly staff through competence tests and additional training, to make sure such malfunctions don’t happen again.

The rocket producer will also take apart two other rockets that have been recently assembled and are due to launch in the coming weeks and then re-assemble them, Skorobogatov said.

They do not say how the damage occurred. It also appears that, like all government run operations, no one will be fired. (The Russians only fire people when they are going to criminally indict them.)

Dawn’s last look at Ceres

10:14 am

Ceres

The Dawn mission has ended, and the image on the right, reduced to post here, is one of its last views of Ceres, with the bright spots of Occator Crater clearly visible, before its fuel ran out. You can see the full resolution image by clicking on the image.

This photo of Ceres and the bright regions in Occator Crater was one of the last views NASA’s Dawn spacecraft transmitted before it depleted its remaining hydrazine and completed its mission.

This view, which faces south, was captured on Sept. 1, 2018 at an altitude of 2,340 miles (3,370 kilometers) as the spacecraft was ascending in its elliptical orbit. At its lowest point, the orbit dipped down to only about 22 miles (35 kilometers), which allowed Dawn to acquire very high-resolution images in this final phase of its mission. Some of the close-up images of Occator Crater are shown here.

Occator Crater is 57 miles (92 kilometers) across and 2.5 miles (4 kilometers) deep and holds the brightest area on Ceres, Cerealia Facula in its center and Vinalia Faculae in its western side. This region has been the subject of intense interest since Dawn’s approach to the dwarf planet in early 2015.

If NASA made any specific announcement about the end of the mission, I have missed it. Either way, this end is not a surprise, because they have made it clear for the past few months that the spacecraft was about to run out of fuel.

They have also posted today an image of Ceres’ largest mountain, Ahuna Mons.

Update: Even as I posted this, NASA sent out this press release: NASA’s Dawn mission comes to an end

China tests its own grasshopper

10:02 am

China has completed its first vertical rocket landing test, using a prototype small scale first stage very similar to SpaceX’s Grasshopper test rocket.

If I was cynical, I’d say that this isn’t just similar, it is a direct steal from Grasshopper. But then, that is generally how the Chinese have come up with their new technology, not by creating it themselves, but by stealing ideas from others and then upgrading them.

Either way, this test shows that China is devoting serious energy to making its first stages reusable.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Company focused on cleaning up space junk raises $50 million

9:54 am

Capitalism in space: Astroscale, a Japanese company with British ties, has raised $50 million in investment capital for developing a robot spacecraft for locating and removing space junk from orbit.

The company plans to use the funding to support several ongoing efforts, including the development of a technology demonstration satellite called ELSA-d. That spacecraft, scheduled for launch in early 2020 on a Soyuz rocket, will feature “target” and “chaser” satellites to demonstrate rendezvous and proximity operations. The target spacecraft is being built by British smallsat developer Surrey Satellite Technology Ltd. under a contract announced last November.

The funding will support scaling up an operations center Astroscale established in the United Kingdom in 2017 that also handles engineering, procurement and business development. Astroscale said it plans to establish an office in the United States in 2019.

The article notes also that much of this money comes from Japanese investors, including Mitsubishi, and reflects a growing interest in Japan in private commercial space.

Planetary Resources bought by blockchain company

9:47 am

Capitalism in space: The so-called asteroid mining company Planetary Resources has now been bought by computer blockchain company.

Planetary Resources said in a statement that it was acquired by ConsenSys, Inc. in an “asset-purchase transaction.” The companies did not disclose specific terms of the agreement. Chris Lewicki, the president and chief executive of Planetary Resources, and Brian Israel, the company’s general counsel, will join ConsenSys as part of the deal.

ConsenSys describes itself as a “blockchain venture production studio focused on building and scaling tools, disruptive startups, and enterprise software products powered by decentralized technology, specifically Ethereum.” Ethereum itself is a decentralized computing platform best known for supporting a cryptocurrency called Ether similar to the better-known bitcoin.

Don’t ask me how ConsenSys makes its money. I haven’t the faintest. I also haven’t the slightest idea what they intend to do with Planetary Resources. I can say without doubt that it won’t be asteroid mining.

OSIRIS-REx snaps image of target asteroid Bennu

9:41 am

Bennu

OSIRIS-REx has snapped its sharpest image yet of its target asteroid Bennu, set for a rendezvous on December 3. The image on the right is that image, at full resolution but cropped.

This “super-resolution” view of asteroid Bennu was created using eight images obtained by NASA’s OSIRIS-REx spacecraft on Oct. 29, 2018 from a distance of about 205 miles (330 km). The spacecraft was moving as it captured the images with the PolyCam camera, and Bennu rotated 1.2 degrees during the nearly one minute that elapsed between the first and the last snapshot. The team used a super-resolution algorithm to combine the eight images and produce a higher resolution view of the asteroid. Bennu occupies about 100 pixels and is oriented with its north pole at the top of the image.

It is beginning to appear that the OSIRIS-REx engineering team is going to have the same kind of problems now faced by the Hayabusa-2 engineering team. In this first glance Bennu appears very similar to Ryugu, a rubble pile shaped approximately like a box, rotating on one point. If so, they are also going to find it difficult to locate a smooth landing site.

Bennu by the way is in an orbit that makes a collision with the Earth possible in the late 22nd century. Knowing its composition, density, and solidity is critical for determining what to do, should that collision become likely.

Russia releases video of October Soyuz launch, showing failed strap-on release

9:17 am

Russia has released video from the outside of its Soyuz rocket during the failed October 11 Soyuz launch, showing one of the rocket’s four strap-on boosters not releasing properly.

The key moment of the video, embedded below, is at 1:25. The booster on the left does not appear to release at its top. The article at the link says the Russians now believe that a failed sensor prevented the opening of a valve that would allow the venting of oxygen to push the booster away.

Parker begins first perihelion fly-by of Sun

9:10 am

It’s getting hot in here: The Parker Solar Probe has begun its first close orbital fly-by of the Sun, set to last from now until November 11.

This solar encounter encompasses the first perihelion of the mission, the point at which Parker Solar Probe is closest to the Sun. Perihelion is expected at about 10:28 p.m. EST on Nov. 5. The spacecraft will come within 15 million miles of the Sun’s surface and clock in at a top speed of 213,200 miles per hour relative to the Sun — setting new records for both closest solar approach and top heliocentric speed by a spacecraft. At perihelion, Parker Solar Probe will fly through material at about 3.6 million degrees Fahrenheit — but because material in this region is so tenuous, it doesn’t influence the temperature of the spacecraft. However, the Sun’s intense radiation heats the Sun-facing side of the spacecraft’s heat shield, called the Thermal Protection System, to about 820 F.

For several days around the Nov. 5 perihelion, Parker Solar Probe will be completely out of contact with Earth because of interference from the Sun’s overwhelming radio emissions.

The article provides some nice details about the spacecraft’s design.

October 31, 2018 Zimmerman/Pratt podcast

9:27 pm

Today I sent a half hour with Robert Pratt of Pratt on Texas, doing two segments. In the first segment, available here, we discussed the announcement by SpaceX that it was going to do the first flight tests of its Big Falcon Rocket out of its new spaceport in Boca Chica, Texas.

In the second segment, available here, Robert allowed me to vent about the disgusting behavior of the leftist protesters during a moment of silence for those killed by an anti-Semite in Pittsburgh.

Both are worth listening to, especially the second.

The vast northern plains of Mars

3:33 pm

The vast northern plains of Mars

Cool image time! Actually, this image, found in the October image release from the high resolution camera of Mars Reconnaissance Orbiter (MRO), is not that interesting, in its own right. Context is all!

The image on the right is a small section cropped and reduced in resolution from the full image, which you can see by clicking on it. It shows one of the only interesting features in this long image strip, a small mesa sticking out all by itself in a flat featureless plain pockmarked by various small craters.

The release has no caption, though it is entitled “Northern Plains Survey.” The northern plains, while having a lot of interesting features that attract the attention of planetary scientists and thus get photographed at high resolution, is mostly featureless, at least at the resolution of the wide field survey cameras on many Mars orbiters. In order to know what is really there, they need to take high resolution images systematically, of which this image is obviously a part.

Overview image

The problem is that there is so much ground to cover. This particular image was taken of a spot in the middle of the plains just to the north of the drainage outlets from Valles Marineris, as shown by the context map to the right. The tiny white spot to the right in the middle of the blue plains north of those drainage outlets is the location of this image.

Detail area of overview map

To understand how much ground needs to be covered, to the right is a close-up of the area shown by the white box in the first image above, with red rectangles indicating where MRO has already taken images. The white cross is the subject image. As you can see, most of this immense plain has not yet been imaged. It is almost as if they threw a dart to pick this one location. Most everything around it remains unseen at high resolution. Thus, to understand the geology of this one image is hampered because the surrounding terrain remains unknown, in close detail.

Mars is a big place. It is an entire planet, with the same land surface as the Earth’s continents. It still contains many mysteries and unexplored places. It will take generations to see it all.

Early Milky Way collision uncovered by Gaia

12:21 pm

Data from the space telescope Gaia has revealed a Milky Way merger event that occurred about 10 billion years ago.

Using the first 22 months of observations, a team of astronomers led by Amina Helmi, University of Groningen, The Netherlands, looked at seven million stars – those for which the full 3D positions and velocities are available – and found that some 30,000 of them were part of an ‘odd collection’ moving through the Milky Way. The observed stars in particular are currently passing by our solar neighbourhood.

We are so deeply embedded in this collection that its stars surround us almost completely, and so can be seen across most of the sky.

Even though they are interspersed with other stars, the stars in the collection stood out in the Gaia data because they all move along elongated trajectories in the opposite direction to the majority of the Galaxy’s other hundred billion stars, including the Sun. They also stood out in the so-called Hertzprung-Russell diagram – which is used to compare the colour and brightness of stars – indicating that they belong to a clearly distinct stellar population.

The sheer number of odd-moving stars involved intrigued Amina and her colleagues, who suspected they might have something to do with the Milky Way’s formation history and set to work to understand their origins. In the past, Amina and her research group had used computer simulations to study what happens to stars when two large galaxies merge. When she compared those to the Gaia data, the simulated results matched the observations. “The collection of stars we found with Gaia has all the properties of what you would expect from the debris of a galactic merger,” says Amina, lead author of the paper published today in Nature.

At the time, the two galaxies were both probably about the same size, approximately equivalent to the Magellanic Clouds.

Must I mention that there is some uncertainty here? The data is good, and the conclusions seem quite reasonable. At the same time, the data is still somewhat thin. We need a lot more Gaia-type telescopes mapping out the motions and positions of all the stars of the Milky Way in far more detail before the uncertainties here will shrink.

Timelapse movie of Supernova 1987A’s evolution from 1992 to 2017

9:42 am

Cool movie time! An astronomy graduate student in Toronto has created a movie showing the steady evolution of the shock wave from Supernova 1987A, the first supernova visible to the naked eye since the discovery of the telescope, during the past twenty-five years.

Yvette Cendes, a graduate student with the University of Toronto and the Leiden Observatory, has created a time-lapse showing the aftermath of the supernova over a 25-year period, from 1992 to 2017. The images show the shockwave expanding outward and slamming into debris that ringed the original star before its demise.

In an accompanying paper, published in the Astrophysical Journal on October 31st, Cendes and her colleagues add to the evidence that the expanding remnant is shaped—not like a ring like those of Saturn’s—but like a donut, a form known as a torus. They also confirm that the shockwave has now picked up some one thousand kilometres per second in speed. The acceleration has occurred because the expanding torus has punched through the ring of debris.

The animation, which I have embedded below the fold, uses images produced by an array radio telescopes in Australia.

Oblique view of Hayabusa-2’s most recent landing rehearsal

9:28 am

Cool movie time! The Hayabusa-2 science team has released a small movie of images taken by a side-mounted camera of the spacecraft’s most recent landing rehearsal, showing the spacecraft ascend from its closest approach from an oblique angle.

I have embedded the movie from these images below the fold. As they note,

Images taken with the small monitor camera (CAM-H) during the Touchdown 1 Rehearsal 3 operation (TD1-R3). One image was captured every second from immediately after the spacecraft began to ascend (altitude 21m) on October 25, 2018 at 11:47 JST. The spacecraft was rising at about 52cm/s.

It appears the closest image was taken from about 21 meters away, about 65 feet, and gives a sense of scale. It also reveals once again how difficult that landing in January is going to be. Though this location is thought to be the smoothest spot on Ryugu, it is still littered with rocks that could cause problems.

Shake-up in SpaceX’s Starlink satellite division

9:16 am

Capitalism in space: It appears that Elon Musk has done a major shake-up in SpaceX’s Starlink satellite division, firing a number of managers because he was unsatisfied with the slow pace of development.

The management shakeup followed in-fighting over pressure from Musk to speed up satellite testing schedules, one of the sources said. SpaceX’s Behrend offered no comment on the matter.

Culture was also a challenge for recent hires, a second source said. A number of the managers had been hired from nearby technology giant Microsoft, where workers were more accustomed to longer development schedules than Musk’s famously short deadlines. Another senior manager that left SpaceX was Kim Schulze, who was previously a development manager at Microsoft, one of the people said. Schulze did not respond to a request for comment.

“Rajeev wanted three more iterations of test satellites,” one of the sources said. “Elon thinks we can do the job with cheaper and simpler satellites, sooner.”

A billionaire and Chief Executive Officer of Tesla Inc, Musk is known for ambitious projects ranging from auto electrification and rocket-building to high-speed transit tunnels.

Musk’s desire for speed here actually makes very good economic sense. There are other companies developing similar internet satellite constellations, and if SpaceX’s launches late they will likely lose a significant market share.

His concern about the slow pace seems to me also justified. This technology, while cutting edge, shouldn’t require as much testing and prototype work as it appears the fired managers wanted. Better to get something working and launched and making money, introducing upgrades as you go, as SpaceX has done so successfully with its Falcon 9 rocket.

NASA decides to continue to ping Opportunity

9:10 am

NASA has decided to continue through January its effort to both listen and send signals to Opportunity in the hope of bringing it to life.

The 45-day deadline passed late last week. But NASA will continue active listening — a strategy that involves both sending commands to Opportunity and listening for any peeps the six-wheeled robot may make — for several more months at least, agency officials announced yesterday. “After a review of the progress of the listening campaign, NASA will continue its current strategy for attempting to make contact with the Opportunity rover for the foreseeable future,” NASA officials wrote in a mission update yesterday. “Winds could increase in the next few months at Opportunity’s location on Mars, resulting in dust being blown off the rover’s solar panels,” they added. “The agency will reassess the situation in the January 2019 time frame.”

This is exactly what the planetary scientists wanted. Their hope is that, with the beginning of dust devil season in November, the chances will then increase for removing the dust that likely covers the rover’s solar panels. It is thought that the rover has a better shot at coming back to life during this time period.

Hawaii Supreme Court rules in favor of TMT

9:04 am

Hawaii’s Supreme Court today upheld by a 4-1 vote the construction permits of the consortium building the Thirty Meter Telescope (TMT) on Mauna Kea.

In its own press release, the TMT consortium said that it “will move forward with fulfilling the numerous conditions and requirements of [the state’s permit] prior to the start of any construction.”

The comments by one of the the telescope’s opponents at the first link are revealing.

Kealoha Pisciotta, one of the main leaders against the telescope, said she’s doesn’t know what their next steps will be, but she’s not hopeful that more legal wrangling will help. “The court is the last bastion in democracy,” she said. “The only other option is to take to the streets. If we lose the integrity of the court, then you’re losing normal law and order, and the only other option is people have to rise up.” [emphasis mine]

Let me translate: We didn’t get our way, so we’re now going to throw another tantrum! Expect more protests and attempts to block construction. Expect the Hawaiian government, dominated almost entirely by Democrats, to fold to those protests. Expect more delays. For example, do you really think the permit process was really done?

State Department of Land and Natural Resources Chairwoman Suzanne Case said the next steps involve telescope builders submitting construction plans. The department will review the plans before issuing permission to proceed.

This was all done almost a decade earlier, and was exactly what the Supreme Court ruled on. To bring it up now suggests the state government is still quietly looking for loopholes to stop the construction, even though the public supports construction and the protesters are a decided minority.

NASA officially retires Kepler

12:42 pm

NASA today officially retired Kepler after nine years of operations.

After nine years in deep space collecting data that indicate our sky to be filled with billions of hidden planets – more planets even than stars – NASA’s Kepler space telescope has run out of fuel needed for further science operations. NASA has decided to retire the spacecraft within its current, safe orbit, away from Earth. Kepler leaves a legacy of more than 2,600 planet discoveries from outside our solar system, many of which could be promising places for life.

Exoplanet hunting however does not end here. Unlike Hubble, astronomers and NASA planned ahead for Kepler’s demise, and this year launched TESS to continue its work, in an even more sophisticated manner.

The steep slumping wall of a Martian volcano caldera

10:19 am

Caldera wall

Cool image time. The Mars Reconnaissance Orbiter science team today released a nice captioned image of the steep wall of the caldera of Ascraeus Mons, the northernmost of the three giant volcanoes that lie to the east of Olympus Mons, the biggest volcano of all. The image on the right, reduced and cropped, shows that steep wall, with full image available by clicking on it. The caption from the release focuses on the fluted upper parts of the wall.

We can see chutes carved into the soft dust that has built up on the slope, with some similarities to gully landforms elsewhere on the planet.

More revealing to me is how this image reveals the slumping that is slowing eroding the caldera’s walls while also making that caldera larger. First, the plateau above the cliff shows multiple small cliffs and pit chains, all more or less parallel to the wall. This suggests that the plateau is over time breaking apart and falling into that caldera. Think of it as an avalanche in slow motion, with the upper plateau separating into chunks as sections slowly tilt down toward eventual collapse. As these chunks separate, they cause cracks to form in that plateau, and hence the parallel cliffs and strings of pits.

On the floor of the caldera we can see evidence of past chunks that did fall, piled up in a series terraces at the base of the wall. These are covered with the soft dust that dominates Martian geology. That soft dust also apparently comprises much of the wall’s materials, and almost acts like a liquid as it periodically flows down the wall, producing the chutes at the top of the wall.

The weak Martian gravity here is an important factor that we on Earth have difficulty understanding. It allows for a much steeper terrain, that also allows structurally weaker materials to hold together that would be impossible on Earth.This image gives a taste of this alien geology, on a large scale.

Curiosity resumes science operations

9:50 am

Though NASA has yet to announce this officially, Curiosity’s science team has made it clear that they are in the process this week of resuming full science operations.

Today was the first day of planning with the full science team since Curiosity had an anomaly on sol 2172. It has been a over a month since we last looked at the “workspace,” the region in front of the rover that the arm can reach, and there were some surprises in store for us! Before the anomaly, the rock was covered with gray-colored tailings from our failed attempt to drill the “Inverness” target, as seen in the Mastcam image from sol 2170. In the new image above, however, those tailings are now gone – and so is a lot of the dark brown soil and reddish dust. So while Curiosity has been sitting still, the winds have been moving, sweeping the workspace clean.

Those operations can also be seen in the images the rover is sending down. For the first time in almost six weeks images are arriving daily, from multiple cameras, and in large numbers.

What we yet don’t have is a detailed description outlining why it took so long to get the second computer up and running, and what they are doing, if anything, to repair the computer that produced the problems last month.

Rocket Lab adds two more satellites to its November 11 launch

9:43 am

Capitalism in space: Rocket Lab has signed on a new customer for its next Electron launch on November 11, adding two more satellites to the rocket’s payload.

US/New Zealand orbital launch provider Rocket Lab has signed a contract with Australian Internet of Things (IoT) start-up Fleet Space Technologies to launch two satellites from Fleet’s Proxima series, which will form the foundation of a global IoT communications constellation. The satellites have been added to the manifest for Rocket Lab’s upcoming mission, ‘It’s Business Time’, scheduled for launch on November 11 from Rocket Lab’s Launch Complex-1 on New Zealand’s Māhia Peninsula.

The Fleet satellites will join other payloads for the launch: two Spire Global Lemur-2 satellites, the Irvine CubeSat STEM Program (ICSP) IRVINE01 educational CubeSat, NABEO, a drag sail technology demonstrator designed and built by High Performance Space Structure Systems GmBH and a GeoOptics Inc. satellite, built by Tyvak Nano-Satellite Systems.

Thus, a lot will be riding on the success of this launch. It will only be the third time the company has attempted to launch Electron. So far, they have only had one successful launch.

SpaceX confirms it will do first hopper tests of BFR in Boca Chica

9:34 am

Capitalsm in space: SpaceX has now confirmed that it will do the first hopper flight tests of its Big Falcon Rocket (BFR) in its new spaceport facility in Boca Chica, Texas.

They hope to start these flight tests as soon as late 2019, but don’t be surprised if they don’t meet that date. It also appears that these test flights will be of the BFR’s first stage as well as its upper stage, presently dubbed the Big Falcon Spaceship (BFS). This upper stage is being designed somewhat like a space shuttle, capable of gliding into the atmosphere in order to shed speed. Unlike the shuttle, however, it will then land vertically.

In related news, the Air Force has admitted that it is having discussions with SpaceX about someday using the BFR to transport cargo from point-to-point, on the Earth.

The article at the link gives the impression that the Air Force is discussing this with multiple companies, but right now the only rocket being designed and built that would be capable of doing this at a reasonable price would be SpaceX’s BFR.

Neil Armstrong’s personal collection up for auction

9:25 am

Neil Armstrong’s collection of space and personal memorabilia is now being put up for auction.

The items up for auction span Armstrong’s life, from his Boy Scout cap to the Wright Flyer fragments. But other items Heritage thinks will generate interest include a small American flag that went to the moon and back with Armstrong, as well as an envelope signed by him, astronaut Buzz Aldrin and their third crewmate, Michael Collins. The envelope was considered “insurance cover” that family members could sell if the astronauts failed to return.

The auction will be held this week, on November 1st and 2nd. It is the first time material from Armstrong has ever been made available for purchase.

Parker sets new records in its flight to the Sun

9:19 am

The Parker Solar Probe has set two new space records, first for making the closest approach to the Sun as well as becoming the fastest spacecraft ever.

The spacecraft passed the current record of 26.55 million miles from the Sun’s surface on Oct. 29, 2018, at about 1:04 p.m. EDT, as calculated by the Parker Solar Probe team. The previous record for closest solar approach was set by the German-American Helios 2 spacecraft in April 1976. As the Parker Solar Probe mission progresses, the spacecraft will repeatedly break its own records, with a final close approach of 3.83 million miles from the Sun’s surface expected in 2024.

“It’s been just 78 days since Parker Solar Probe launched, and we’ve now come closer to our star than any other spacecraft in history,” said Project Manager Andy Driesman, from the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. “It’s a proud moment for the team, though we remain focused on our first solar encounter, which begins on Oct. 31.”

Parker Solar Probe is also expected to break the record for fastest spacecraft traveling relative to the Sun on Oct. 29 at about 10:54 p.m. EDT. The current record for heliocentric speed is 153,454 miles per hour, set by Helios 2 in April 1976.

We ain’t seen nothin’ yet. This is only the first orbit. With each later orbit the spacecraft will zip past the Sun faster, and closer.

Russia to disassemble the next Soyuz rocket scheduled for launch

9:08 am

In order to make sure it was assembled correctly and will separate properly, Russian engineers plan to disassemble the four strap-on boosters of the next scheduled Soyuz rocket and then put it back together for its November launch.

I wonder however if they are studying this assembly process to figure out why the manned Soyuz rocket that failed on October 11 was assembled badly so that they can revise that process. It sounds like they are merely checking to make sure the rocket is put together right, without figuring out what went wrong.
