UK Tories purge 21 who opposed party today

11:36 pm

The Conservative Party in Great Britain today expelled 21 members who voted against Prime Minister Boris Johnson’s plan to exit the European Union, deal or no deal.

[The expulsion plan was announced] just hours after lawmakers in Britain passed legislation designed to stop Johnson from taking the UK out of the European Union without a formal deal. The House of Commons earlier Tuesday passed a bill allowing members of Parliament to introduce legislation forcing Johnson to ask for a three-month extension from the EU if a deal is not made by Oct. 31, the Brexit deadline.

The bill passed in a 328 to 301 vote, with 21 members of the governing Conservative Party defecting and joining the opposition party, The Guardian reported.

Johnson has also announced that he will call for general elections, to decide if his party should remain in power. At the moment it appears he does not have a majority in parliament to rule.

At the same time, Johnson has soared in the polls for his hardline exit strategy, and it also appears this strategy is garnering him international political support.

If Johnson wins in the elections, he will have succeeded in purging his party of the equivalent of what conservatives in the U.S. call RINOs, fake conservatives who mouth the right thing but don’t really mean it and when push comes to shove always betray the people who voted for them. This will put Johnson in a very strong political position for doing what he was chosen to do, uphold the choice of the electorate when they voted to leave the European Union.

SpaceX issues explanation for nonresponse in potential satellite collision issue

12:54 pm

SpaceX today issued an explanation for why it had not responded when ESA officials had asked them to change the orbit of one of its Starlink smallsats to protect against a possible collision with ESA’s Aeolus spacecraft.

SpaceX, in a statement Sept. 3, said it was aware of a potential conjunction Aug. 28 and communicated with ESA. At that time, though, the threat of a potential collision was only about 1 in 50,000, below the threshold where a maneuver was warranted. When refined data from the U.S. Air Force increased the probability to within 1 in 1,000, “a bug in our on-call paging system prevented the Starlink operator from seeing the follow on correspondence on this probability increase,” a company spokesperson told SpaceNews.

“SpaceX is still investigating the issue and will implement corrective actions,” the spokesperson said of the glitch. “However, had the Starlink operator seen the correspondence, we would have coordinated with ESA to determine best approach with their continuing with their maneuver or our performing a maneuver.”

This incident increasingly strikes me as a tempest in a teapot created by ESA for any number of reasons, including their overall dislike of SpaceX (for generally making all government-run space programs look foolish). There is also this quote from an ESA official in the article above:

“The case just showed that, in the absence of traffic rules and communication protocols, collision avoidance has to rely on the pragmatism of the involved operators,” Krag said. “This is done today by exchange of emails. Such a process is not viable any longer with the increase of space traffic.” He said that, if the Space Safety initiative is funded, ESA would like to demonstrate automated maneuver coordination by 2023. [emphasis mine]

I can just see ESA officials drooling with eager anticipation the coming of more “traffic rules and communication protocols,” partly inspired by this fake crisis they just created. Imposing more rules and getting increased funding is what they do best, since it certainly isn’t exploring space with creative and efficient innovation.

Boris Johnson loses one-vote majority in House of Commons

9:58 am

In the continuing political battle in the British parliament over the decision by the voters to leave the European Union and prime minister Boris Johnson’s effort to abide by that decision quickly, a member of his Tory Party defected from that party today in a public stunt.

Boris Johnson has seen his one-vote Commons majority vanish before his eyes, as a statement by the prime minister to parliament was undermined by the very public defection of the Conservative MP Phillip Lee to the Liberal Democrats.

The stunt, in which the pro-remain Bracknell MP walked across the chamber to the Lib Dem benches flanked by two of his new colleagues, happened as Johnson updated the Commons on last month’s G7 summit, a statement devoted mainly to Brexit.

At the start of a crucial day in the Commons, Johnson condemned a backbench plan aimed at delaying Brexit to avert a no-deal departure, calling it a “surrender bill”. Jeremy Corbyn responded by criticising the PM’s language. MPs will vote on Tuesday evening on whether to take control of the order paper to allow the passage of the bill. Johnson has promised to seek a general election if they do so.

It is very clear that Great Britain has the same political problem as the United States: an entrenched elitist power structure that doesn’t wish to abide by the popular will, and is willing to do almost anything to maintain its power, even if that means corrupting or even destroying the democratic institutions that have made western civilization possible.

Hayabusa-2 in safe mode for one day on August 29

9:36 am

Japan’s Hayabusa-2 space probe automatically entered safe mode for one day on August 29, causing engineers to postpone a planned operation set for Sept 5.

Hayabusa2 is equipped with four reaction wheels that are used to control the posture of the spacecraft, and posture control is usually performed using three of these reaction wheels. On August 29, the back-up reaction wheel that has not been used since October last year was tested, and an abnormal value (an increased torque) as detected. The spacecraft therefore autonomously moved into the Safe-Hold state. Details of the cause of the abnormal torque value are currently under investigation. On August 30, restoration steps were taken and the spacecraft returned to normal. However, as the spacecraft moved away from the home position due to entering Safe-Hold, we are currently having to return to the home position. We will return to the home position this weekend.

The attitude of the spacecraft is controlled by three reaction wheels as before. Entering the Safe-Hold state is one of the functions employed to keep the spacecraft safe, which means that procedures have worked normally.

In this case it is very clear that this event actually demonstrated that the spacecraft’s systems are operating properly to prevent it from becoming lost. However, the event also underlined the urgency of getting its samples from the asteroid Ryugu back to Earth.

Lunar lander company PTScientists purchased

9:28 am

Capitalism in space: The private commercial lunar lander company PTScientists has been purchased by an unknown investor, thereby avoid liquidation after declaring bankruptcy in July.

Berlin-based PTScientists and the law firm Görg, which handled the company’s bankruptcy administration, announced the acquisition in a German-language statement published Sept. 2. The announcement said neither the company buying PTScientists nor the purchase price would be disclosed, but that the deal was effective Sept. 1.

The acquisition, the announcement stated, allows PTScientists to retain its staff of about 60 people who had been working on lunar lander concepts, including a study for the European Space Agency of a mission to send a lander to the moon to perform experiments for in-situ resource utilization. ESA awarded that study to a team that included PTScientists as well as launch vehicle company ArianeGroup in January.

It seems that someone decided that this company was worth saving, and that it (and the private construction of private planetary missions) has the potential to make them money in time.

Parker completes third fly-by of Sun

9:22 am

The Parker Solar Probe has completed its third close fly-by of the Sun.

At just before 1:50 p.m. EDT on Sept. 1, 2019, NASA’s Parker Solar Probe completed its third close approach of the Sun, called perihelion. At the time of perihelion, the spacecraft was about 15 million miles from the Sun’s surface, traveling at more than 213,200 miles per hour.

Mission controllers at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, received a green “A” beacon from the spacecraft soon after perihelion, meaning all systems were performing as designed and that the spacecraft was in good health.

As they had the science instruments turned on sooner during this close approach, and will let them operate longer afterward, they will get more data then on the previous two close approaches.

Vikram completes first de-orbit burn

9:45 pm

The new colonial movement: India’s Vikram lunar lander has successfully completed its first de-orbit engine burn, lasting 4 seconds, adjusting its orbit slightly in preparation for landing on the Moon on September 7.

They will do a second burn tomorrow, further adjusting the orbit.

Note that the update says that this burn was by Chandrayaan-2, but this must be a mistake. The Vikram lander separated from the Chandrayaan-2 orbiter yesterday, and it is Vikram that is doing the orbital changes and will land on the Moon.

SpaceX declines to shift Starlink satellite to avoid collision

2:12 pm

When European Space Agency (ESA) engineers realized there was a greater than normal chance that a new SpaceX Starlink satellite could collide with ESA’s already orbiting Aeolus satellite, they asked SpaceX to shift its orbit, only to have SpaceX decline.

According to Holger Krag, head of the Space Debris Office at ESA, the risk of collision between the two satellites was 1 in 1,000 – ten times higher than the threshold that requires a collision avoidance maneuver. However, despite Aeolus occupying this region of space nine months before Starlink 44, SpaceX declined to move their satellite after the two were alerted to the impact risk by the U.S. military, who monitor space traffic. “Based on this we informed SpaceX, who replied and said that they do not plan to take action,” says Krag, who said SpaceX informed them via email – the first contact that had been made with SpaceX, despite repeated attempts by Krag and his team to get in touch since Starlink launched. “It was at least clear who had to react. So we decided to react because the collision was close to 1 in 1,000, which was ten times higher than our threshold.”

As to why SpaceX refused to move their satellite, that is not entirely clear (the company did not respond to a request for comment). Krag suspected it could be something to do with SpaceX’s electric propulsion system, which “maybe is not reacting so fast” as the chemical propulsion on board Aeolus.

The article is clearly spun to make SpaceX look bad, though based on the stated facts the company shot itself in the foot quite ably. If their propulsion system could not have done the job as well as the other satellite, they should have simply said so and worked with ESA to get the issue fixed, rather than simply saying they would do nothing.

Vikram has successfully separated from Chandrayaan-2

9:11 am

The new colonial movement: India’s lunar lander, Vikram, has successfully separated from Chandrayaan-2, and is functioning nominally in lunar orbit.

The update describing this is the second update at the link, with the first detailing the arrangements for the press to cover the landing on September 7.

The lander carries the rover, dubbed Pragyan, which will roll off Vikram only a few hours after landing.

Chandrayaan-2 now in proper lunar orbit for release of lander/rover

7:45 pm

India’s Chandrayaan-2 spacecraft today completed its fifth engine burn in lunar orbit, placing it in the correct orbit for releasing its lander/rover.

The next operation is the separation of Vikram Lander from Chandrayaan-2 Orbiter, which is scheduled on September 02, 2019, between 1245 – 1345 hrs (IST). Following this, there will be two deorbit maneuvers of Vikram Lander to prepare for its landing in the south polar region of the moon.

The landing itself is scheduled for September 7.

Police ramp up violence against Hong Kong protesters today

12:12 am

This weekend’s Hong Kong protests against China’s rule resulted in increased violence by the police against the protesters.

In the evening, clashes between police and demonstrators broke the peaceful rhythm in the afternoon rallies, repeating the pattern of past weekend protests. Police deployed water cannon trucks several times, unleashing blue-dyed water that would make it easier for police to identify frontline protesters. Police chased down protesters and beat them up with batons, injuring multiple people in the head. One person was injured in the left eye, reportedly by a police-fired projectile.

On Hennessy Road, where many protesters had gathered, police fired multiple rounds of tear gas and sponge grenades. Police also confirmed that they fired two live rounds near Victoria Park. There were no reported injuries in the area. It is unclear why police decided to deploy their service weapons at the time.

Toward midnight, violence spread into subway stations in Kowloon district. At the Prince Edward metro station and several other stations in Kowloon, police charged into the station and into train cars, deploying pepper spray and beating their batons. Officers arrested at least a dozen individuals. Several unarmed passengers were seen bleeding from injuries.

More details at the link. It appears that the protests were peaceful for most of the day, until the police decided to move in and try to shut them down.

Has Yutu-2 found something unusual?

9:08 am

According to Chinese sources, China’s lunar rover Yutu-2 has spotted something unexpected and unusual on the surface of the far side of the Moon.

On July 28, the Chang’e-4 team was preparing to power Yutu-2 down for its usual midday ‘nap’ to protect the rover from high temperatures and radiation from the sun high in the sky. A team member checking images from the rover’s main camera spotted a small crater that seemed to contain material with a color and luster unlike that of the surrounding lunar surface.

The drive team, excited by the discovery, called in their lunar scientists. Together, the teams decided to postpone Yutu-2’s plans to continue west and instead ordered the rover to check out the strange material. With the help of obstacle-avoidance cameras, Yutu-2 carefully approached the crater and then targeted the unusually colored material and its surroundings. The rover examined both areas with its Visible and Near-Infrared Spectrometer (VNIS), which detects light that is scattered or reflected off materials to reveal their makeup.

VNIS is the same instrument that detected tantalizing evidence of material originating from the lunar mantle in the regolith of Von Kármán crater, a discovery Chinese scientists announced in May.

So far, mission scientists haven’t offered any indication as to the nature of the colored substance and have said only that it is “gel-like” and has an “unusual color.” One possible explanation, outside researchers suggested, is that the substance is melt glass created from meteorites striking the surface of the moon.

The report is at present too vague to really tell us anything. What I predict is that this discovery will almost certainly not be as strange or alien as this report makes it sound.

ISS partners okay Trump changes to Gateway

9:02 am

The various international nations that partner on ISS and wish to partner on NASA’s Gateway project issued a statement this week saying that they approve the changes imposed on that lunar space station by the Trump administration, all of which significantly delay their participation.

In an Aug. 28 statement, members of the station’s Multilateral Coordination Board (MCB), which includes the five space agencies involved in the ISS, said the Gateway is “a critical next step” in human space exploration and that they plan to contribute modules or other elements for the facility in lunar orbit.

“Looking to exploration activities beyond LEO, the MCB members reaffirmed their continued intention to cooperate on a human outpost in the lunar vicinity – Gateway,” the document, a summary of the board’s Aug. 6 meeting, stated. “Within a broader open architecture for human exploration, the MCB acknowledged the Gateway as a critical next step.”

The board offered a similar endorsement of the Gateway at a March 5 meeting. The statement from that meeting included a diagram of one Gateway configuration, with contributions from Canada, Europe, Japan and Russia, as well as the United States, identified.

Three weeks after that meeting, though, Vice President Mike Pence announced at a meeting of the National Space Council that the U.S. would speed up its lunar exploration timeline, seeking to land astronauts on the moon by 2024, rather than prior plans for a 2028 landing. NASA subsequently said that it would initially pursue a minimal Gateway needed for that 2024 landing, deferring full-fledged development of the Gateway for a second phase intended to enable “sustainable” lunar exploration in the second half of the 2020s. [emphasis mine]

The “minimal Gateway” that the Trump administration is presently pursuing is structured to shift focus from a space station in lunar orbit to landing on the Moon. This means that many of the later components of Gateway, to be built or used by these international partners, will be significantly delayed, or even made unnecessary.

So, why did these space agencies all endorse the new plan that circumscribed their participation? They have no choice. Without NASA’s SLS, they have no way to get to the Moon. And without Gateway, SLS has no reason to exist. These government space agencies need SLS (as ephemeral as SLS might be) because it is the only free government launch option available to them. They hope, by endorsing what the Trump administration has done, to convince it to go along with the complete Gateway project, including the continued funding of SLS, thus creating a gigantic international boondoggle (paid for mostly by the U.S.) that will justify all their manned space programs.

This is another reason to dump SLS. Wouldn’t it be better for the U.S. to have its private commercial space launch industry sell its goods to these leeches, rather than have them living off our taxpayers’ dime? We will gain nothing from them with Gateway, as it is presently structured, while they feed off of us. If instead they needed to buy launch services from private rockets, the profits would accrue to U.S. companies and citizens, and help encourage competition and more innovation.

If we instead buy into this international boondoggle, we will spend a lot of money for very little space exploration, even as we make the bureaucrats at six government space agencies (including NASA) very happy.

China launches two smallsats

8:25 am

Using its Kuaizhou-1A solid rocket, China’s pseudo-private company ExSpace launched two smallsats into orbit yesterday.

This rocket, using technology developed for the military, including a mobile launch platform, is designed to compete directly with Rocket Lab and the other western private smallsat rockets trying to come on line right now. Its development appears to have been wholly funded by the Chinese government, which revealed after the launch that they plan between 8 and 9 more launches before the end of the year.

The leaders in the 2019 launch race:

14 Russia
14 China
10 SpaceX
6 Europe (Arianespace)
4 India
4 Rocket Lab
4 ULA

The U.S. continues to lead 19-14 in the national rankings.

Hong Kong arrests three prominent protest leaders

1:05 pm

In a sign that China has no intention of compromising with the protesters in Hong Kong, authorities there today arrested three of the most high-profile leaders of the protest movement.

Two were active in protests in 2014.

Joshua Wong and Agnes Chow, who rose to eminence as the student leaders of pro-democracy demonstrations in 2014, were detained Friday, ahead of what is expected to be a tense weekend in the city. Authorities banned a march planned for Saturday, and warned they would use force and possibly arrest those who defy the order.

Police said Wong and Chow face charges of participating in an unauthorized assembly and inciting others to participate in an unapproved assembly, while Wong faces an additional charge of organizing an unapproved assembly, in relation to a June 21 protest at police headquarters. Both were released on bail Friday. …

The sweep came ahead of a sensitive political anniversary in the semiautonomous Chinese territory. This Saturday marks five years since Beijing announced an electoral-reform plan that denied Hong Kong free elections — a decision that triggered 79 days of pro-democracy protests.

More here, including information about other arrests in addition to the three above.

I’m not sure China’s actions here are going to prevent demonstrations tomorrow. For example,

The bespectacled Wong, who was 17 when he became the face of the student-led civil disobedience movement in 2014 that blocked major roads for 79 days, has not been a prominent figure in the latest protests, which have no identifiable leaders.

The same thing applies to the others who were arrested. There doesn’t appear to be anyone in particular running these protests, which means arresting a few scapegoats and banning further demonstrations will probably not work. We shall find out this weekend.

Scientists look at and compare two past grand minimums

11:55 am

In a new paper just published by the American Geophysical Union (AGU), scientists have used tree ring data to analyze and compare the last two past grand minimums, dubbed the Spörer Minimum (1432–1578) and the more well known Maunder Minimum (1640–1720).

The link takes you to the full paper. It is very technical but what it essentially finds is that there appear to be some differences between the two, but more important, during the deepest part of both grand minimums all evidence of the 11 year sunspot cycle (dubbed the Scwabe cycle) vanishes.

A detailed comparison between the Spörer and Maunder (CE 1640–1720) minima shows that the Spörer Minimum is associated with enhanced Δ14C variability in a band centered around the 11‐year Schwabe cycle from CE 1450 to 1479 and between CE 1545 and 1578, whereas little 11‐year variability is observed from CE 1479 to 1539. In contrast, we only observe enhanced 11‐year variability after the end of the Maunder Minimum at CE 1722–1744, which could indicate that the nature and origin of the two minima were different.

In other words, from 1479 to 1539 (Spörer) and 1545 to 1722 (Maunder) the data suggests that we would not have seen sunspots, even with today’s superior observational capabilities.

They base this conclusion by looking at carbon-14 data, which reflects the arrival of cosmic rays on the Earth. When the sun is active cosmic rays decrease. When it is inactive, with no sunspots, cosmic rays increase. This data can be compared with known and more recent sunspot cycles, and can thus provide a robust baseline for determining what the Sun’s behavior was like before the era of the telescope.

China’s FAST radio telescope discovers 93 new pulsars

9:53 am

The research team running China’s FAST radio telescope, the largest single dish such telescope in the world, have announced that they have discovered 93 new pulsars since October 2017.

China might still be having trouble finding a big name astronomer to run the telescope, but in the meantime it looks like their own people are taking advantage of the situation to use the telescope establish their own names.

New Russia Soyuz spacesuits interfere with Russia pee tradition

9:49 am

Only in Russia: The newly designed Russian spacesuits for use by astronauts during ascent and descent in the Soyuz capsule apparently do not have a fly that will allow the continuation of a long-standing Russian tradition initiated by Yuri Gagarin on his way to the launchpad for his historic spaceflight.

The Sokol-M prototype suit was designed as a replacement for suits worn during launches to the International Space Station (ISS) on Soyuz spacecraft. … The maker of the suits, the aerospace firm Zvezda, says they will be made of new materials and adaptable to different body sizes.

But the new design makes it impossible to carry out one particular ritual launched by the first man in space, Yuri Gagarin, who had to relieve himself on the back wheel of the bus that was taking him to the launch pad in 1961.

The stop has been replicated at every launch from the Baikonur launch pad and, many male cosmonauts and astronauts pee on the tyre for good luck – something that would be impossible in the new suit, according to its maker. Female astronauts are not obligated to participate but some have brought vials of their urine to splash on the wheel instead.

“I’m not sure how they will be able to (carry on the tradition), since we haven’t designed the fly,” said the Zvezda director, Sergei Pozdnyakov, quoted by Russian agencies. “We have the design specifications. They don’t state that it’s necessary to pee on the wheel. The design specifications would need to be adapted.”

I suspect, knowing how important traditions and rituals are to the Russians, that the Russian government will require a design change to allow this tradition to continue.

FAA required SpaceX to up its insurance for Starhopper test

9:40 am

The FAA’s office that regulates commercial space required SpaceX to increase its insurance coverage for this week’s Starhopper test to $100 million, thirty three times higher than their coverage for the previous Starhopper hops.

Lots of information at the link, though in summary it all makes perfect sense.

There are a number of likely reasons the federal regulator required SpaceX to boost its insurance coverage, says George Nield, a former FAA associate administrator who led its Office of Commercial Space Transportation (OCST) for more than a decade.

One is that Tuesday’s launch took Starhopper hundreds of feet higher than in July; during the prior flight, SpaceX’s vehicle only went about 60 feet (18 meters) up before landing. “The higher you want to go, the more propellant you’re going to have to load, and the more propellant you load, the bigger the boom if it were to explode,” Nield told Business Insider prior to Tuesday’s launch.

More importantly, their Boca Chica launch site is only a mile and a half from a small village of about twenty people, much closer than any other launchpad in the world. How SpaceX will manage this issue should they wish to test fly their fullscale Starship prototype from this site I really do not know. It could be that they won’t, and will confine all test flights to Kennedy, where they are also building a second Starship prototype.

Kennedy Space Center prepares for hurricane

9:27 am

In preparation for the possibility of Hurricane Dorian’s arrival next week, the Kennedy Space Center is shutting down, including moving the giant mobile launcher vehicle, with the SLS launch tower on it, indoors to protect both.

The agency on Wednesday moved its hulking Apollo-era crawler-transporter out to Launch Complex 39B in order to bring the massive Mobile Launcher inside for the storm. That deployment must be made promptly because the crawler-transporter travels at just 1 mph (1.6 km/h).

The launch tower itself is 400 feet (122 meters) tall, which makes it a clear hazard in the high winds of a hurricane. NASA decided today (Aug. 29) that Dorian is threatening enough to merit moving the launch tower into Kennedy’s cavernous 52-story Vehicle Assembly Building for safety.

Their caution makes sense. Expect NASA to also announce that this two week delay in work will cause them several months more in delays to the SLS program. That has been their pattern over the years.

ISS atmosphere issue?

9:19 am

Though NASA and Roscosmos both say the crews are in no immediate danger, alarms on ISS have indicated an issue with the oxygen levels on the station.

“The crew and the space station are in no immediate danger and are continuing normal operations,” the spokesperson said. “The overall atmosphere inside the station remains will below the O2 concentration limits. Teams are working to identify the root cause of the issue,” he added.

This report states that the problem is “the high oxygen content in the air in the Russian Zvezda module.”

If the problem was a drop in atmospheric pressure, the issue would likely be more serious, and suggest a repeat of the 2018 leak caused by a hole drilled in a Soyuz capsule. That the problem instead is high oxygen levels, suggests something more benign.

OSIRIS-REx’s four candidate landing sites

9:07 am

The OSIRIS-REx engineering team has released a short video that flies over in close-up, showing the spacecraft’s four candidate sites on the asteroid Bennu, one of which will be where they will do a touch-and-go sample grab.

They continue to accumulate data on the four sites, all of which pose issues and risks because of nearby boulders and the looseness of Bennu’s rubble pile make-up.

Though all the sites are being considered, my sources in the industry suggest that the two dubbed Sandpiper and Nightingale are being favored. I like Osprey, because it is inside a crater and looks clear, but then, what do I know?

Russia’s Rockot launches military geodesic satellite

8:51 am

Russia today used its re-purposed ballistic missile, Rockot, to launch the second in a two-satellite constellation of military geodesic satellites, designed to more accurately map the Earth’s gravitational field.

This launch puts Russia in the lead in the annual race for most launches for the first time since 2018. It also gives them more launches for the year than they had predicted. Both facts demonstrate that their launch industry is showing a recovery from the problems experienced in 2016, when they discovered corruption in one of their main rocket engine companies, requiring the recall of all engines.

The leaders in the 2019 launch race:

14 Russia
13 China
10 SpaceX
6 Europe (Arianespace)
4 India
4 Rocket Lab
4 ULA

The U.S. still leads Russia in the national rankings, 19 to 14.

Cliff collapse on Mars

2:38 pm

Cliff collapse on Mars
Click for full image.

Cool image time! The photograph to the left, rotated, cropped, and reduced to post here, was found in the August image release of the high resolution camera on Mars Reconnaissance Orbiter (MRO).

This was an uncaptioned image, with a title “Cataract and Grooves in Kasei Valles.” Kasei Valles is the giant canyon north of Marineris Valles. Though it is not as well known or maybe as dramatic, it is about as long and vast as its more famous southern canyon. It also has some very intriguing features, including what I consider to so far be the pit on Mars with the highest priority for exploration.

The image on the right shows the result when a giant section of this cliff face broke off and collapsed into the canyon. It also shows that the collapse occurred a long time ago. Not only are there newer craters on the collapse debris, the breakdown at the cliff base looks well eroded, as if many eons have passed since it piled up there.

When this section broke off however it was a very big event. The width of the collapse is about a mile across, with its depth about 600 feet. The height of the cliff is approximately 3000 feet, give or take a few hundred feet. Thus the chunk that broke off was about 600 feet wide, 5,000 feet long, and about 3,000 feet high. That’s one very big rock.

Apparent Iran launch failure

9:54 am

Just released satellite photos showing fire and smoke at an Iranian launchpad suggest that a rumored attempt by Iran this week to launch a satellite into orbit resulted instead in a launchpad failure.

[S]atellite images by Planet Labs Inc. showed a black plume of smoke rising above a launch pad there, with what appeared to be the charred remains of a rocket and its launch stand. In previous days, satellite images had shown officials there repainted the launch pad blue.

On Thursday morning, half of that paint apparently had been burned away. “Whatever happened there, it blew up and you’re looking at the smoldering remains of what used to be there,” said David Schmerler, a senior research associate at the Middlebury Institute of International Studies.

Schmerler told The Associated Press that the images of the space center suggested that the rocket either exploded during ignition or possibly briefly lifted off before crashing back down on the pad.

In July Iranian officials had said they would do three launches this year, with a communications satellite launch expected before the end of the summer. It would appear that this failure is of that launch.

Space Command to launch today

9:18 am

The military today will initiate a new military office dubbed the Space Command, thereby consolidating its space operations into one office.

U.S. Air Force Gen. John Raymond will serve as the first head of Space Command (SPACECOM). At launch, Raymond will lead 87 active units handling operations such as missile warning, satellite surveillance, space control and space support, Gen. Joseph Dunford said at a meeting of the National Space Council earlier this month.

The rest of the linked article is focused on the politics of Trump’s desire to turn this command into a new branch of the military, a Space Force, while facing opposition in Congress and the Pentagon. The goal however from the beginning was to end the scattershot nature of the military’s space bureaucracy, and it appears, on the surface, that the Space Command has done this.

Whether things stand as they are however is doubtful. Creating a new military branch is a wonderful opportunity for Washington power-brokers to find ways to spend money. For example, some estimates have said that the new Space Force could cost $1 to $2 billion more. You think these thieves and crooks in Washington will be able to resist that?

Of course, there really is no reason for this new agency to cost so much extra. In fact, the Space Command as created now probably adds nothing to the budget, and in fact probably has the chance to save money. And it even makes the military’s space operations more robust and efficient.

I therefore expect the powers-that-be in Washington to move to change that.

Comey skips free

8:59 am

The law is only for little people: Despite a damning Justice Deparment inspector general report that concluded that James Comey had violated the law and broke FBI rules by leaking classified information when he was FBI director, the Justice Department has decided not to prosecute him.

“We conclude that Comey’s retention, handling, and dissemination of certain Memos violated Department and FBI policies, and his FBI Employment Agreement,” reads DOJ watchdog head Michael Horowitz’s report.

The watchdog office said Comey broke FBI rules by giving a memo containing unclassified information to his friend Daniel Richman with instructions to share the contents with a reporter. The office also said Comey failed to notify the FBI after he was fired that he had retained some of the memos in a safe at home. Comey wrote a series of memos about conversations with President Trump he said unnerved him. Comey has stated he wanted to make a record of the interactions because he was concerned President Trump might later lie about them.

Attorney General William Barr will not prosecute the fired FBI director over his wrongdoings.

We are no longer a nation of laws, but of corrupt power and banana republic backroom deals. By aligning himself with the Democratic Party, Comey has obtained that get-out-of-jail card that all Democrats hold. No matter what laws they break, no one in Washington will ever prosecute them, especially if they are in positions of power and are popular commentators on mainstream liberal press outlets like CNN.

Be a Republican, or a conservative, or even an ordinary citizen, however, and be prepared for the entire legal book to be thrown at you instantly, should you even jaywalk.

NASA Inspector General to Congress: Free Europa Clipper from SLS

8:44 am

In a letter to Congress on August 27, 2019, NASA’s inspector general has called for Congress to immediately abandon the legal requirement it imposed on Europa Clipper to fly on NASA’s SLS rocket, thereby allowing NASA to choose any commercial rocket to launch the spacecraft.

The letter [pdf] is amazingly blunt.

[W]e write to highlight an issue at NASA that we believe requires immediate action by Congress. Language in NASA’s appropriation legislation requires the Agency to launch a satellite to Europa, a moon of Jupiter, in 2023 on the yet-to-be-completed Space Launch System (SLS) rocket. However, because of developmental delays and, more significantly, NASA’s plans to use the first three SLS rockets produced for its Artemis lunar program, an SLS will not be available until 2025 at the earliest. Consequently, if completed on its projected schedule, the approximately $3 billion dollar Europa spacecraft (known as “Europa Clipper”) will need to be stored for at least 2 years at a cost of $3 to $5 million per month until an SLS becomes available. NASA recently added $250 million in Headquarters-held reserves to the project to address these storage and related personnel costs.

Congress could reduce risks to both the Europa mission and Artemis program while potentially saving taxpayers up to $1 billion by providing NASA the flexibility in forthcoming fiscal year (FY) 2020 appropriations legislation to determine the most cost effective and timely vehicle to launch the Europa Clipper mission in 2023 or whenever the satellite is completed.

As blunt as the letter is, the wording above is also very careful to hide the fact that the $1 billion savings will come, not from avoiding the launch delay, but from buying a private commercial launch vehicle (estimated launch cost about $100 million) versus using SLS (estimated launch cost of $1 billion to $4 billion).

Will Congress take this advice? It should, though I am pessimistic. Our Congress has not shown much interest in doing the smart thing when it comes to SLS for about a decade. Why should things change now?

Engineers attach test helicopter to Mars 2020

2:41 pm

Engineers have now attached to the Mars 2020 rover the test helicopter that will attempt to make the first air-born flight on another world.

The Mars Helicopter is considered a high-risk, high-reward technology demonstration. If the small craft encounters difficulties, the science-gathering of the Mars 2020 mission won’t be impacted. If the helicopter does take flight as designed, future Mars missions could enlist second-generation helicopters to add an aerial dimension to their explorations.

“Our job is to prove that autonomous, controlled flight can be executed in the extremely thin Martian atmosphere,” said JPL’s MiMi Aung, the Mars Helicopter project manager. “Since our helicopter is designed as a flight test of experimental technology, it carries no science instruments. But if we prove powered flight on Mars can work, we look forward to the day when Mars helicopters can play an important role in future explorations of the Red Planet.”

If this works on Mars, MiMi Aung will be in a position to win contracts for similar helicopters for the rest of her life. It seems to me that this project has been her baby from the beginning.
