Sunspot update August 2019: Even fewer sunspots

3:38 pm

Silso graph for August 2019

Last month I titled my sunspot update “Almost no sunspots,” as there were only two sunspots for the entire month of July, with one having the polarity for the next solar maximum.

August however beat July, with only one sunspot for the month, and none linked to the next maximum. To the right is the Silso graph of sunspot activity for August, showing just one sunspot for the month, on only one day, August 13.

Below is NOAA’s August graph of the overall sunspot cycle since 2009, released by NOAA today and annotated to give it some context.

Exploding nitrogen on Titan

10:52 am

A new theory proposes that some of the smaller high rimmed methane lakes on Titan were formed when underground nitrogen warmed and exploded, forming the basin in which the methane ponded.

Most existing models that lay out the origin of Titan’s lakes show liquid methane dissolving the moon’s bedrock of ice and solid organic compounds, carving reservoirs that fill with the liquid. This may be the origin of a type of lake on Titan that has sharp boundaries. On Earth, bodies of water that formed similarly, by dissolving surrounding limestone, are known as karstic lakes.

The new, alternative models for some of the smaller lakes (tens of miles across) turns that theory upside down: It proposes pockets of liquid nitrogen in Titan’s crust warmed, turning into explosive gas that blew out craters, which then filled with liquid methane. The new theory explains why some of the smaller lakes near Titan’s north pole, like Winnipeg Lacus, appear in radar imaging to have very steep rims that tower above sea level – rims difficult to explain with the karstic model.

This is a theory that has merit. It also must be treated with skepticism, as our knowledge of Titan remains at this time very superficial, even with the more detailed information garnered from Cassini.

Chandrayaan-2 locates Vikram

8:28 am

According to K. Sivan, the head of ISRO, India’s space agency, their Chandrayaan-2 orbiter has captured a thermal image of Vikram on the lunar surface, pinpointing the lander’s location.

They have not released the image. According to reports today, they do not yet know the lander’s condition, and have not regained communications. Reports late yesterday had quoted K.Sivan as saying “It must have been a hard-landing.” That quote is not in today’s reports.

In watching the landing and the subsequent reports out of India, it appears that India is having trouble dealing with this failure. To give the worst example, I watched a television anchor fantasize, twenty minutes after contact had been lost, that the lander must merely be hovering above the surface looking for a nice place to land. Most of the reports are not as bad, but all seem to want to minimize the failure, to an extreme extent.

Their grief is understandable, because their hopes were so high. At the same time, you can’t succeed in this kind of challenging endeavor without an uncompromising intellectual honesty, which means you admit failure as quickly as possible, look hard at the failure to figure out why it happened, and then fix the problem. If India can get to that place it will be a sign that they are maturing as a nation. At the moment it appears they are not quite there.

Vikram fails to land on Moon

1:26 pm

Vikram, India’s first attempt to soft land on the Moon, apparently has failed, with something apparently going wrong in the very last seconds before landing.

As I write this they have not officially announced anything, but the live feed shows a room of very unhappy people.

It is possible the lander made it and has not yet sent back word, but such a confirmation should not take this long.

India’s prime minister, Narendra Modi, was given a very short briefing by K. Sivan, head of ISRO, and then apparently left without comment. This I found an interesting contrast to the actions of Israel’s prime minister Benjamin Netanyahu when its lunar lander Beresheet failed in landing earlier this year. Netanyahu came out to comfort the workers in mission control, congratulating them for getting as far as they had. Modi apparently simply left. UPDATE: Modi has reappeared to talk to the children who had won a contest to see the landing as well as people in mission control. After making a public statement he has now left.

They are now confirming that communications was lost at 2.1 kilometers altitude, which was just before landing. They are analyzing the data right now to figure out what went wrong.

Watch Vikram landing on Moon

10:55 am

Vikram's primary landing site

The new colonial movement: I have embedded below the live stream of India’s attempt today to land its Vikram lander on the Moon, broadcast by one of their national television networks.

The landing window is from 4:30 to 5:30 pm Eastern. This live stream is set to begin about 3 pm Eastern.

If you want to watch ISRO’s official live stream you can access it here.

Some interesting details: Vikram is named after Vikram A. Sarabhai, who many consider the founder of India’s space program. The lunar rover that will roll off of Vikram once landing is achieved is dubbed Pragyan, which means “wisdom” in Sanskrit. Both are designed to operate on the Moon for one lunar day.

The landing site will be about 375 miles from the south pole.

That spot is a highland that rises between two craters dubbed Manzinus C and Simpelius N. On a grid of the moon’s surface, it would fall at 70.9 degrees south latitude and 22.7 degrees east longitude.

The white cross on the image to the right is where I think this site is. The secondary landing site is indicated by the red cross.

Update on SpaceX’s plans for Starship

9:20 am

According to FAA regulatory documents, SpaceX has updated its development plan for Starship, including changes in its overall plans for its Boca Chica facility.

The document also lays out a three-phase test program, which it says “would last around 2 to 3 years”:

Phase 1: Tests of ground systems and fueling, a handful of rocket engine test-firings, and several “small hops” of a few centimeters off the ground. The document also includes graphic layouts, like the one above, showing the placement of water tanks, liquid methane and oxygen storage tanks (Starship’s fuels), and other launch pad infrastructure.

Phase 2: Several more “small hops” of Starship, though up to 492 feet (150 meters) in altitude, and later “medium hops” to about 1.9 miles (3 kilometers). Construction of a “Phase 2 Pad” for Starship, shown below, is also described.

Phase 3: A few “large hops” that take Starship up to 62 miles (100 kilometers) above Earth — the unofficial edge of space — with high-altitude “flips,” reentries, and landings.

The first phase is now complete, with the company shifting into Phase 2.

Boca Chica meanwhile is no longer being considered a spaceport facility. Instead, its focus will now be a development site for building Starship and Super Heavy.

Results released of July Vega launch failure investigation

9:15 am

The European Space Agency (ESA) this week released the results of its investigation into the July 10, 2019 launch failure of Arianespace’s Vega rocket, the first such failure after 14 successful launches.

The failure had occurred about the time the first stage had separated and the second stage Z23 rocket motor was to ignite. The investigation has found that the separation and second stage ignition both took place as planned, followed by “a sudden and violent event” fourteen seconds later, which caused the rocket to break up.

They now have pinned that event to “a thermo-structural failure in the forward dome area of the Z23 motor.”

The report says they plan to complete corrective actions and resume launches by the first quarter of 2020.

Township shuts fire company because one member spoke to Proud Boys

1:42 pm

They’re coming for you next: A local Pennsylvania township has shut down an entire voluntary fire company because it refused to blacklist a member who also happened to have expressed interest in joining the Proud Boys organization.

Officials in Haverford Township, in Delaware County, were informed on Aug. 12 that a volunteer with the Bon Air Fire Company was affiliated with “an organization described as an extremist group,” the township’s manager David Burman wrote in a statement released Thursday.

The township immediately launched an investigation, which included interviewing the volunteer, who admitted he was involved with the Proud Boys, Burman said. The volunteer revealed he had attended social gatherings hosted by the group and had passed two of the group’s four initiation steps, “which includes hazing.”

Burman’s statement quoted the group’s “self-proclaimed basic tenet,” posted on their website, that they are “Western chauvinists who refuse to apologize for creating the modern world.” The proclamation belongs to the Proud Boys, who “are known for anti-Muslim and misogynistic rhetoric,” according to the Southern Poverty Law Center, which designates them as a hate group. Women and transgender men are not allowed in the group.

While the volunteer “indicated that he had attempted to distance himself from the group in recent months” Burman and a police official met with Bon Air Fire Company officials on Aug. 14 to address “the seriousness of this matter and urged the fire company to address it.”

Burman said he was informed the next day that the volunteer had offered his resignation, but the Bon Air Fire Company chief had refused to accept it. A week later, Burman said he received an email that said the fire company’s board had “found no basis for terminating the volunteer’s membership.”

First, the accusations of bigotry by the Southern Poverty Law Center are pure slander and libel. There is no evidence of this. The Proud Boys are admittedly a male-only organization, but so what? This isn’t proof of bigotry, no matter what the modern idiotic political correct leftist interpretation claims. And the organization’s proud favoring of western civilization over other cultures, such as Islam, actually has strong empirical proof, for anyone who has read any history at all. These slanders are part of Obama’s legacy of hate, whereby liberals now have the freedom to label anyone who disagrees with them bigots and hate-mongers, without any evidence.

I applaud the fire company for standing up for the freedom of speech of one of its members. I wish that there would be an outpouring of support for them in this locality in Pennsylvania. They should be honored for defending freedom, and telling the local petty dictators on the township’s government to go to hell.

Terraced and banded hills on Mars

1:13 pm

Banded or terraced hills in eastern Hellas
Click for full image.

Cool image time! In my review of the most recent download of images from Mars Reconnaissance Orbiter’s (MRO) the high resolution camera, I found a very startling (and cool) image of some dramatic terraced Martian hills, taken on July 30, 2019. I wanted to post it here, but decided to first do some more digging, and found that an earlier image, taken in 2017, showed more of this particular hill. It is this earlier image posted to the right, cropped and reduced.

Don’t ask me to explain the geology that caused this hill to look as it does. I can provide some basic knowledge, but the details and better theories will have to come from the scientists who are studying this feature (who unfortunately did not respond to my request for further information).

What I can do is lay out what is known about this location, as indicated by the red box in the overview map below and to the right, and let my readers come up with their own theories. The odds of anyone being right might not be great, but it will be fun for everyone to speculate.

Democrats at climate forum: Ban everything!

9:24 am

Fascists: When asked by CNN interviewers during that network’s seven hour pro-Democratic climate forum yesterday what they would do to prevent global warming, it appears that the primary solution by every Democratic presidential candidate was to ban things.

Democrats appearing at CNN’s marathon 7-hour global warming forum have a plan to solve a changing climate: Ban everything!

Over the course of the television extravaganza, Democrats’ leading 2020 presidential candidates floated a variety of proposals to cut Americans’ energy use and, ostensibly, to stop the climate from changing. Among them: Bans on plastic straws, red meat, incandescent lightbulbs, gas-powered cars, nuclear energy, off-shore drilling, fracking, natural gas exports, coal plants, and even “carbon” itself.

The article goes on to detail each candidate’s banning proposals, all of which were similar, mindless, and based on an incredible level of ignorance about the climate and science. Bernie Sanders however probably gave us the most revealing and honest glimpse into all their mindsets with his suggestion that human life itself was the problem.

Sen. Bernie Sanders (I-Vt.) went the furthest, saying we should try to minimize human life itself to help the environment. Sanders said he’d use taxpayer money to help fund 3rd world population control programs: “The answer has everything to do with the fact that women in the United States of America, by the way, have a right to control their own bodies and make reproductive decisions. And the Mexico City agreement, which denies American aid to those organizations around the world that allow women to have abortions or even get involved in birth control to me is totally absurd.” [emphasis mine]

No one should be surprised by this. Every socialist/communist/totalitarian movement in the past has always led inevitably to the killing of millions. For them, their ideas are much more important than people, and should those people get in the way, well then, they must be removed, by force and by gas chambers if necessary.

Be prepared. Should one of these power-hungry leftists win the White House they will be coming for you next.

The bit rate of human languages

9:04 am

Language scientists think they have determined that the universal bit rate for transmitting information across multiple languages is about 39 bits per second.

Scientists started with written texts from 17 languages, including English, Italian, Japanese, and Vietnamese. They calculated the information density of each language in bits—the same unit that describes how quickly your cellphone, laptop, or computer modem transmits information. They found that Japanese, which has only 643 syllables, had an information density of about 5 bits per syllable, whereas English, with its 6949 syllables, had a density of just over 7 bits per syllable. Vietnamese, with its complex system of six tones (each of which can further differentiate a syllable), topped the charts at 8 bits per syllable.

Next, the researchers spent 3 years recruiting and recording 10 speakers—five men and five women—from 14 of their 17 languages. (They used previous recordings for the other three languages.) Each participant read aloud 15 identical passages that had been translated into their mother tongue. After noting how long the speakers took to get through their readings, the researchers calculated an average speech rate per language, measured in syllables/second.

Some languages were clearly faster than others: no surprise there. But when the researchers took their final step—multiplying this rate by the bit rate to find out how much information moved per second—they were shocked by the consistency of their results. No matter how fast or slow, how simple or complex, each language gravitated toward an average rate of 39.15 bits per second, they report today in Science Advances. In comparison, the world’s first computer modem (which came out in 1959) had a transfer rate of 110 bits per second, and the average home internet connection today has a transfer rate of 100 megabits per second (or 100 million bits). [emphasis mine]

When I went to Russia the first time in 1995 I used to joke with my caving friends there that the real reason the U.S. won the cold war was that English words routinely used one syllable for the three required by Russian and thus we could get things done in one third the time. I would start listing comparable words, (for example “good” vs “khah-rah-shoh” and “please” vs “pa-ZHAL-sta”) and challenge them to come up with any example where the Russian word had fewer syllables. It drove them crazy because they couldn’t do it.

I was joking of course. It makes sense that the information rates should actually be pretty much the same, as this study suggests. However, the highlighted words also suggest that the subtle differences should also not be ignored.

San Fran government declares NRA (and its members) terrorists

2:12 pm

They’re coming for you next: The San Francisco Board of Supervisors, all Democrats, yesterday voted unanimously to declare the National Rifle Association a domestic terrorist organization.

[The resolution blames the] NRA … for causing gun violence. “The National Rifle Association musters its considerable wealth and organizational strength to promote gun ownership and incite gun owners to acts of violence,” the resolution reads. The resolution also claims that the NRA “spreads propaganda,” “promotes extremist positions,” and has “through its advocacy has armed those individuals who would and have committed acts of terrorism.”

In addition to calling the NRA a domestic terrorist organization, the Board of Supervisors called on the city and county of San Francisco to “take every reasonable step to limit … entities who do business with the City and County of San Francisco from doing business” with the NRA.

You can read the resolution here [pdf]. Its aim is to blacklist this legal organization made of about five million Americans. It also aims to forbid any legal agreements between any businesses in San Francisco and the NRA, as well as encourage all other city, state, and federal governments to do the same.

Ah, blacklists! I remember them well. There was once a time that Democrats considered blacklists to be the font of all evil, and proof that anyone who suggested them was a fascist. Now that the left proposes such things they stand for justice and righteousness.

Nor is this the only example. Recently several Hollywood television actors called for the publication of all attendees to a Trump fundraiser in Beverly Hills, so that they could make a list of people to blacklist. Fortunately, a lot of other Hollywood stars balked, criticizing the idea.

Nonetheless, this is where the leftist Democratic Party is headed. Either you agree with them, or you must be squelched, in every way possible.

China withdraws extradition bill that sparked Hong Kong protests

10:36 am

The Hong Kong government today announced that it is withdrawing the extradition bill demanded by China that sparked Hong Kong protests.

Carrie Lam, Hong Kong’s chief executive, said Wednesday that the government would withdraw a contentious extradition bill that ignited months of protests in the city, moving to quell the worst political crisis since the former British colony returned to Chinese control 22 years ago.

The move eliminates a major objection among protesters, but it was unclear if it would be enough to bring an end to intensifying demonstrations, which are now driven by multiple grievances with the government.

“Incidents over these past two months have shocked and saddened Hong Kong people,” she said in an eight-minute televised statement broadcast shortly before 6 p.m. “We are all very anxious about Hong Kong, our home. We all hope to find a way out of the current impasse and unsettling times.”

Her decision comes as the protests near their three-month mark and show little sign of abating, roiling a city known for its orderliness and hurting its economy.

The article suggests that the protests will still go on, that the “genie is out of the bottle.” I am not so sure.

Regardless, what this means is that, as of now, China is admitting that its effort to eliminate Hong Kong’s democratic systems and fold it completely into the communist power structure of the mainland has failed. This does not mean that China will stop trying, merely that they will now pause in this effort.

The end of the Thirty Meter Telescope?

9:54 am

The arriving dark age: It appears that the protests in Hawaii that are preventing the construction of the Thirty Meter Telescope might end up killing the telescope completely.

The problem is twofold. First, the Democratic-controlled government in Hawaii is willing to let the protesters run the show, essentially allowing a mob to defy the legal rulings of the courts:

The Native Hawaiian protesters blocking the construction of the Thirty Meter Telescope (TMT) on the summit of Mauna Kea appear to have settled in for the long haul. After 2 months of protests, their encampment on the Mauna Kea access road has shops, a cafeteria, and meeting spaces. “It’s like a small village,” says Sarah Bosman, an astronomer from University College London who visited in July. “There are signs up all over the island. It was a bit overwhelming really.”

Second, there is opposition to the alternate backup site in the Grand Canary Islands, both from local environmental groups and from within the consortium that is financing the telescope’s construction.

Astronomers say that the 2250-meter-high site, about half as high as Mauna Kea, is inferior for observations. Canada, one of six TMT partners—which also include Japan, China, India, the California Institute of Technology, and the University of California—is especially reluctant to make the move and could withdraw from the $1.4 billion project, which can ill afford to lose funding. Finally, an environmental group on La Palma called Ben Magec is determined to fight the TMT in court and has succeeded in delaying its building permit. It says the conservation area that the TMT wants to build on contains archaeological artifacts. “They’re willing to fight tooth and nail to stop TMT,” says Thayne Currie, an astronomer at the NASA Ames Research Center in Mountain View, California.

We now live in a culture that is opposed to new knowledge. It is also a culture that prefers mob rule, giving power to the loudest and possibly most violent protesters, while treating the law as a mere inconvenience to be abandoned at the slightest whim of those mobs.

If this doesn’t define a dark age, I’m not sure what does.

Vikram makes second and last lunar orbital change

9:40 am

The new colonial movement: India’s Vikram lunar lander today made its second and last orbital change, preparing itself for landing on the Moon on September 7.

The orbit of Vikram Lander is 35 km x 101 km. Chandrayaan-2 Orbiter continues to orbit the Moon in an orbit of 96 km x 125 km and both the Orbiter and Lander are healthy.

With this maneuver the required orbit for the Vikram Lander to commence it descent towards the surface of the Moon is achieved. The Lander is scheduled to powered descent between 0100 – 0200 hrs IST on September 07, 2019, which is then followed by touch down of Lander between 0130 – 0230 hrs IST

They plan to roll the rover Pragyan off of Vikram about two hours after landing.

This article provides a nice overview of the mission.

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

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.
