The steep mountain slopes inside Valles Marineris
Click for full image.

Time for another cool image showing the dramatically steep terrain of Valles Marineris on Mars, the largest known canyon in the solar system. The picture to the right, cropped, reduced, and enhanced to post here, was taken on October 31, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists rightly label this picture “Steep Slopes in West Melas Chasma”. The red dot marks the high point on this ridgeline. The green dot at the upper left marks the lowest point in the picture, about 4,800 feet below the peak. The blue dot on the right edge marks the low point on the ridge’s eastern flank, about 4,600 feet below the peak. The cliff to the east of the peak drops quickly about 1,300 feet in less than a mile.

On the overview map above, the white dot marks the location. The inset is an oblique view, created from a global mosaic of MRO’s context camera images, with the white rectangle indicating approximately the area covered by the picture above.

The immense scale of Valles Marineris must once again be noted. The elevations in this picture are comparable to the descent you make hiking down from the South Rim of the Grand Canyon. They pale however when compared to Valles Marineris. In the inset I have indicated the rim and floor of Valles Marineris in this part of the canyon. The elevation distance between the two is 18,000 feet.

In other words, the canyon to the east of this ridge is quite comparable in size to the Earth’s Grand Canyon, and it is hardly noticeable within the larger canyon of Valles Marineris.

Musk touts SpaceX’s gigantic lead in sending mass to orbit in 2023

The mass sent to orbit in 2023
Click for original image.

In a tweet Elon Musk sent out yesterday, he noted that “SpaceX is tracking to launch over 80% of all Earth payload to orbit this year.”

The graphic to the right was included in Musk’s tweet. Despite the delays in developing its heavy-lift Starship/Superheavy rocket, mostly caused by government red tape since the arrival of Joe Biden in the White House, the company’s smaller Falcon 9 and Falcon Heavy rockets have still been able to launch more than fifteen times the mass into orbit that its nearest competitor, the nation of China.

I count launches by company or nation as a indicator of rocketry success. The mass-to-orbit metric is as important, if not more so, though the two are without doubt linked. Both measure the success of those trying to become major players in the launch market.

And in both metrics, SpaceX is wiping the floor with its competition.

The big 25th anniversary of ISS is really still two years away

In a press release today NASA touted the 25th anniversary of the mating in orbit of the first two modules of the International Space Station (ISS), Zarya (built by Russia but paid for by the U.S.) and Unity (built by Boeing for NASA).

25 years ago today, the first two modules of the International Space Station – Zarya and Unity – were mated during the STS-88 mission of space shuttle Endeavour. The shuttle’s Canadarm robotic arm reached out and grappled Zarya, which had been on orbit just over two weeks, and attached it to the Unity module stowed inside Endeavour’s payload bay. Endeavour would undock from the young dual-module station one week later beginning the space station assembly era.

Though this anniversary is nice, it really isn’t the most significant. The most significant ISS anniversary is still two years away, when we celebrate 25 years of continuous human presence in space. That record began on October 31, 2000, when a Soyuz-2 rocket lifted off from Baikonur in Kazahkstan, carrying American Bill Shepherd and Russians Yuri Gidzenko and Sergei Krikalev on what was to be the first crew occupancy of the station. Since that launch humans have occupied ISS without break.

With the present operation of China’s space station, and about four American commercial stations under development as well as plans by India and Russia to build their own, it is very likely that October 30, 2000 will remain the last day in human history where no human was in space.

That is the significant date. That is the moment in history that should be noted and marked as significant.

SpaceX initiates new round to obtain from $500 to $750 million in additional private investment capital

8:45 am

SpaceX has opened another tender round to obtain from $500 to $750 million in additional private investment capital, with the company now valued at $175 billion, up from the previous valuation of $150 billion.

With this new capital, the company will have raised at a minimum around $12 billion from private sources, not including the undisclosed investment in October from Italy’s biggest bank.

Why are private investors willing to do commit so much cash to this company? This quote from the article says it all:

SpaceX is on track to book revenues of about $9 billion this year across its rocket launch and Starlink businesses, Bloomberg News reported last month, with sales projected to rise to around $15 billion in 2024. The company is also discussing an initial public offering for Starlink as soon as late 2024 — a bid to capitalize on robust demand for communications via space.

In other words, SpaceX is already earning enough to pay for the development of Starlink/Starship/Superheavy, with even bigger profits expected because it has such a lead on its competitors in the satellite broadband business.

These investors realize that SpaceX has captured the majority of this market share, and because of this it will be difficult for late arrivals like Amazon to enter the market. Amazon could charge less to gain market share, but SpaceX could then do the same. And SpaceX will already be in the black when it does so, while Amazon will instead be increasing its red ink.

This situation underlines the wisdom of Musk’s decision in 2018 to shake-up the management in SpaceX’s Starlink division because the management then was setting too slow a pace. As I wrote then:

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.

Time has now proven Musk right.

SpaceX launches more Starlink satellites

11:53 pm

SpaceX tonight successfully launched another 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage successfully completed its ninth flight, landing on a drone ship in the Atlantic.

The leaders in the 2023 launch race:

90 SpaceX
56 China
16 Russia
7 Rocket Lab
7 India

American private enterprise now leads China in successful launches, 102 to 56, and the entire world combined 102 to 90. SpaceX by itself is once again tied with the rest of the world (excluding other American companies) 90 to 90. The fast pace in launches continues, however, with five launches scheduled in the next five days.

Another example of the inability of Democrats to condemn bigotry

2:49 pm

House vote condemning anti-Semitism
Final totals of House vote condemning anti-Semitism.
Click for source.

This column today might sound familiar, as I have reported similar examples numerous times before (See previous essays here, here, here, here, and here). Yet, it is important to document the inability of the modern Democratic Party to unequivocally condemn bigotry, because so much of its base and membership are actually are in favor of such things.

Yesterday the House passed a resolution condemning the horrible rise of anti-Semitism seen nationwide and globally, mostly expressed during pro-Hamas demonstrations that have often descended into violence and calls for the murder of all Jews in Israel.

The resolution [pdf] is quite clear. After listing numerous examples of harrassment and violence against Jews in the U.S., Australia, Israel, and globally, it condemned such behavior, and made it clear that the term “anti-Zionism” is simply a euphemism for anti-Semitism.

The final vote totals are shown in the screen capture to the right, taken from C-SPAN. As you can see, except for one nay vote and four not voting at all, the entire Republican caucus voted in favor of this resolution.

The Democrats however were not so unanimous. While a little less than half of the Democrats in the House voted in support of this amazingly simple resolution, half voted “present”, following the instructions of Congressemen Jerry Nadler (D-New York), Dan Goldman (D-New York), and Jamie Raskin (D-Maryland) (all members of the Democratic Party House leadership). These Congressmen opposed the resolution because it is…

Big Martian gullies partly filled with glacial material

Overview map

Big Martian gullies partly filled with glacial material

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 18, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists dub as “large gullies with infilled alcoves.”

Gullies on Mars were one of the first discoveries by orbiters of small-scalle potential water-caused features on the Red Planet. The favorite explanation for their formation today involves the seasonal freeze-thaw cycle, combined with the deposition of ice and dry ice frost in the winter. When that ice and dry ice sublimates away in the spring it causes collapse and erosion, widening the gullies.

These gullies also exhibit evidence that underground and glacial ice might contribute as well. The material in the largest gullies looks like a mixture of glacial material and dust and debris. It could also be that there is ice impregnated in the ground, which can cause large collapses when it sublimates away.

The white rectangle on the overview map and inset above marks the location of this picture, on the western rim of a 13-mile-wide unnamed crater inside the western portion of the 2,000-mile-long mid-latitude strip on Mars I dub glacier country, since every image from orbit shows evidence of glaciers.

This picture is no different, as the horizontal cracks at the base of the crater rim suggests the glacier that fills the crater floor is being pulled apart by gravity at its edges. The elevation drop from the top of the rim to the floor is about 3,200 feet, so any ice on that slope will definitely be stressed by gravity. Such cracks are therefore not surprising.

Psyche takes its first pictures

9:49 am

The spacecraft Psyche — going to the metal asteroid Psyche — has successfully taken its first pictures, proving its camera and pointing system work as planned.

The pictures, taken on December 4, 2023 from about 16 million miles from Earth, are actually quite boring, merely showing a field of stars. However,

The imager instrument, which consists of a pair of identical cameras, captured a total of 68 images, all within a star field in the constellation Pisces. The imager team is using the data to verify proper commanding, telemetry analysis, and calibration of the images. …The imager takes pictures through multiple color filters, all of which were tested in these initial observations.

At this moment all looks good for Psyche’s eventual arrival at Psyche in 2029.

NASA completes investigation into the failure of the OSIRIS-REx drogue parachute

9:43 am

When the sample return capsule brought OSIRIS-REx’s Bennu samples back to Earth on September 24, 2023, it appeared that the drogue parachute never released prior to the release of the capsule’s main parachutes. Fortunately, those main parachutes were able to do the job, putting the capsule down unharmed but a minute early.

NASA has now completed its investigation into the drogue chute failure. According to its press release:

After a thorough review of the descent video and the capsule’s extensive documentation, NASA found that inconsistent wiring label definitions in the design plans likely caused engineers to wire the parachutes’ release triggers such that signals meant to deploy the drogue chute fired out of order.

The drogue was expected to deploy at an altitude of about 100,000 feet. It was designed to slow and stabilize the capsule during a roughly five-minute descent prior to main parachute deployment at an altitude of about 10,000 feet. Instead, at 100,000 feet, the signal triggered the system to cut the drogue free while it was still packed in the capsule. When the capsule reached 9,000 feet, the drogue deployed. With its retention cord already cut, the drogue was immediately released from the capsule.

In other words, engineers wired the thing incorrectly so it cut its cords before it was released. To further confirm this conclusion engineers will inspect the system thoroughly once scientists have completed removing the Bennu samples from the capsule.

Iran and China complete orbital launches

9:35 am

Iran's launch December 6, 2023
Iran’s Salman rocket lifting off today.
The launch site itself was not disclosed.

According to the official state-run press of each country, both Iran and China yesterday completed successfully launches, both of which appeared to test new capabilities of some note.

First Iran announced that it had used its Salman rocket to put a 500-kilogram capsule that it said was carrying biological samples, and was also “has the ability to carry a human,” though the mass of this capsule makes that highly unlikely. Little other information was provided. Nor has this orbital launch as yet been confirmed by the orbital monitoring services of the U.S. military. The image to the right is a screen capture from the launch video at the link, and appears to show that this rocket has only one stage, thus making an orbital launch impossible.

Assuming this orbital launch is confirmed, it was Iran’s second orbital launch in 2023 and will therefore not show up on the launch race leader board below. If further information is obtained I will update this post appropriately.

China in turn announced the successful launch today of a test satellite, using its new Smart Dragon-3 solid-fueled rocket lifting off from a barge in the South China Sea 1,300 nautical miles off the coast of Guangdong province, where Hong Kong is located. To arrive at this ocean launch location took five days. The launch thus tested the use of this mobile floating platform from remote ocean locations.

The leaders in the 2023 launch race:

89 SpaceX
56 China
16 Russia
7 Rocket Lab
7 India

American private enterprise still leads China in successful launches, 101 to 56, and the entire world combined 101 to 90. SpaceX by itself now trails the rest of the world (excluding other American companies) 89 to 90, though it has another launch planned for tonight, with the live stream here.

December 5, 2023 Zimmerman/Batchelor/Livingston podcast about Apollo 8

9:14 pm

This podcast was specifically to talk about the Apollo 8 mission to the Moon in 1968, and my book, Genesis: the Story of Apollo 8. John Batchelor and David Livingston allowed me to tell a lot of stories, some from the book and some from my private conversations with the astronauts and their families.

Embedded below the fold in two parts.

Note that I will be doing a much longer interview with John Batchelor on the December 23-24, 2023 weekend about Apollo 8 and my book. John scheduled this preliminary short interview so that his weekday audience (different from his weekend audience) could hear about the book.

Pushback: Macy’s sued for its illegal discriminatory hiring policies

3:35 pm

Banned at Macy's
Banned at Macy’s

Bring a gun to a knife fight: The pro-bono non-profit legal firm America’s First Legal (AFL) has filed a federal civil rights complaint against Macy’s for its blatantly illegal diversity and inclusion policies that required hiring quotas bases solely on race.

You can read the complaint here [pdf]. AFL’s letter to Macy’s announcing the complaint is here [pdf]. As noted in AFL’s press release:

In a 2019 press release entitled “Bold Vision To Advance Diversity and Inclusion and Ensure The Company Reflects The Diversity Of The Customers and Communities Served,” Macy’s details its five-point plan with specific directives focused on achieving greater diversity for all aspects of the company’s business model.

The plan explicitly instructs Macy’s management to “[a]chieve more ethnic diversity by 2025 at senior director level and above, with a goal of 30 percent,” as well as to initiate a “12-month program designed to strengthen leadership skills for a selected group of top-talent managers and directors of Black/African-American, Hispanic-Latinx, Native American and Asian descent.” Quotas such as these are patently illegal under the law.

The language of that release is quite appalling. » Read more

Mars Reconnaissance Orbiter takes another look at the non-face on Mars

12:51 pm

The non-face on Mars
Click for original image

In 2007, shortly after it began science operations in Mars orbit, the science team for Mars Reconnaissance Orbiter (MRO) pointed its high resolution camera at the so-called “Face on Mars”, taking a picture that confirmed (as had Mars Global Surveyor several years earlier) that this “face” was a non-face, simply a mesa whose features made it appear roughly facelike in low resolution imagery.

Now, more than sixteen years later, scientists have used MRO to take a new picture of the non-face mesa. That picture is to the right, cropped, reduced, and sharpened to post here. Compared to the 2007 photo the new photo has far better lighting conditions, revealing many details on the mesa’s eastern half that were mostly obscured by shadows previously.

In fact, these new details strongly suggest that the depression on the mesa’s eastern slopes harbors a decaying glacier. At least, that is what the features there resemble.

Ingenuity completes its 67th flight on Mars

9:58 am

Overview map
Click for interactive map.

Almost immediately after communications were re-established with Mars after the monthlong solar conjunction — where the Sun stood between the Earth and Mars — the Ingenuity engineering team uploaded instructions for Ingenuity’s 67th flight, and on December 2, 2023, the helicopter successfully completed that flight, traveling 1,289 feet to the west at a height of 39 feet for 136 seconds, almost exactly what the flight planned dictated.

The overview map above shows with the green dot the helicopter’s new position after that flight. It has moved ahead of Perseverance into Neretva Vallis, the gap out of Jezero Crater through which the rover will eventually travel. At the moment however Perseverance sits much farther east, as indicated by the blue dot, where it has been studying the surface geology of the delta that once flowed through that gap into the crater.

Stratolaunch completes first test captive carry flight with powered Talon hypersonic vehicle

9:34 am

Test engineering vehicle attached below Roc
Test engineering vehicle attached to Roc during
a flight in October 2022

Stratolaunch has successfully completed the first test captive carry flight with its prototype Talon hypersonic vehicle fueled and powered, carried by its giant Roc airplane.

The flight was the twelfth for the company’s launch platform Roc and the first in which the aircraft carried a Talon vehicle with live propellant as part of a buildup approach for Talon-A’s first powered flight.

The flight lasted a total of three hours and 22 minutes and represented a significant step forward in the company’s near-term goal of completing a powered flight with the Talon-A vehicle, TA-1. A primary objective was to evaluate Talon-A’s propulsion system and the Talon environments while carrying live propellant. A second objective was to verify Roc and TA-1’s telemetry systems, which provides the situational awareness to ensure all systems are ready for powered flight during the release sequence.

The company has two contracts to do hypersonic test flights using flightworthy Talon vehicles, one with the Air Force and the second with the Navy. It is not clear however when those flights will occur.

China launches two satellites

9:22 am

The Chinese pseudo-company Galactic Energy today successfully launched two satellites, its Ceres-1 rocket lifting off from China’s Jiuquan spaceport in northwest China.

China’s own state-run press illustrates how pseudo this company is by not even mentioning its name in its reporting. It mentions the launch was “commercial,” but that’s as far as it goes. China’s press knows the government runs and owns this company, and only allows it the superficial appearance of a private company to enhance competition within its space industry.

No word on where the rocket’s lower solid-fueled stages crashed inside China.

The leaders in the 2023 launch race:

89 SpaceX
55 China
16 Russia
7 Rocket Lab
7 India

American private enterprise still leads China in successful launches, 101 to 55, and the entire world combined 101 to 88. SpaceX by itself still maintains its lead over the entire world (excluding other American companies) 89 to 88.

Italian subcontractor for Arianespace misplaces two rocket tanks

8:58 am

This story is hard to believe but true: The Italian company Avio, one of the subcontractors for Arianespace that builds its smaller rockets Vega and Vega-C, apparently misplaced two rocket tanks that were to be used on the Vega rocket’s last launch, thus preventing that launch entirely.

The two propellant tanks that went missing were housed in an Avio production department in Colleferro that had undergone renovation work. At some point following the completion of the renovations, the two tanks were found to be missing.

According to the initial source, the tanks had not been entered into a company-wide asset management system that tracked the location of all vital Avio components. This ensured that the teams tasked with investigating the disappearance had very little to go on when beginning their search for the missing tanks.

Despite the futility of the search, the tanks were eventually found. This was, however, not the good news Avio had hoped for. The tanks are, unfortunately, not in a usable state. They had been crushed and were found alongside metal scraps in a landfill.

The tanks power Vega’s fourth stage that deploys satellites in orbit. They were to be used on the final flight of Vega, which has been delayed repeatedly for unexplained reasons. We now know the reason.

Because this was the final flight, however, the tanks cannot be replaced because the Vega production line has been shut down. The company is considering using two of the four qualification tanks first built more than a decade ago when Vega was first being tested, but those were test tanks and have been sitting unused for as long. It will be difficult to determine their reliability.

Europe’s government-run rocket program thus at present has no rocket capable of launching. Its Ariane-5 is retired. Its Vega cannot launch. Its Vega-C, which replaces the Vega, remains grounded due to a launch failure in December 2022, with the next launch expected no earlier than late in 2024. And its new Ariane-6 rocket won’t do its first launch until the summer of 2024, at the earliest.

South Korea successfully test launches a new solid-fueled rocket

8:43 am

South Korea today successfully launched a new solid-fueled rocket on its third test launch and first orbital flight.

The space launch vehicle was launched from a barge floating in waters about 4 kilometers south of Jeju Island at 2 p.m. and placed a small Earth observation satellite into orbit at an altitude of about 650 km, the ministry said.

The 100-kilogram synthetic aperture radar satellite, made by Hanwha Systems, succeeded in sending signals to a ground station at 3:45 p.m., which means it is operating normally, the company said. The rocket is designed to put a small satellite into a low Earth orbit for surveillance operations.

This four-stage rocket uses solid fuel for its first three stages and liquid fuel for the final stage. That it launched from a barge is as significant, as having this ability gives South Korea an added launch flexibility.

This was South Korea’s second launch in 2023, so the leader board for the 2023 launch race remains unchanged:

89 SpaceX
54 China
16 Russia
7 Rocket Lab
7 India

American private enterprise still leads China in successful launches, 101 to 54, and the entire world combined 101 to 87. SpaceX by itself still leads the entire world (excluding other American companies) 89 to 87.

Boeing dropped from competition for Air Force “doomsday” plane

6:09 pm

It appears that by mutual agreement the Air Force has eliminated Boeing in the competition to build a new replacement for the E-4B Nightwatch, what the military calls its “doomsday” airplane, designed to survive a nuclear war.

Sources told Reuters that Boeing – the incumbent manufacturer of the E-4B Nightwatch – could not agree with the USAF on data rights and contract terms for the replacement plane that began flying in the 1970s. In other words, the planemaker did not want to sign a fixed-price agreement.

…”Rest assured, we haven’t signed any fixed-price development contracts nor (do we) intend to,” Brian West, Boeing’s chief financial officer, told investors in October.

With Boeing out of the competition, Sierra Nevada (the parent company of Sierra Space) is left as the only bidder. It is also quite willing to operate under a fixed price contract.

As I noted in a comment thread after a reader first posted a link to this story,

Boeing is signing its own death warrant. The entire federal defense and space agencies are steadily switching to fixed-price, and will simply go to others if Boeing refuses to accept those terms.

In fact, those agencies will want to go to others, because Boeing is making it clear it can’t meet its contractual obligations.

This decision also tells us a great deal about Boeing as a company. Its inability to fulfill any contract under a fixed price means it no longer has the discipline to do anything right. It seems buying products from it at this point might be a very foolish proposition.

Amazon signs launch contract with SpaceX

9:32 am

Amazon on December 1, 2023 announced it has signed a three-launch contract with SpaceX to place its Kuiper satellites into orbit, supplementing the launch contracts it presently has with ULA, Arianespace, and Blue Origin. From the Amazon press release:

SpaceX’s Falcon 9 is a reusable, two-stage launch vehicle designed for the reliable and safe transport of people and payloads into Earth orbit and beyond, and it has completed more than 270 successful launches to date. Project Kuiper has contracted three Falcon 9 launches, and these missions are targeted to lift off beginning in mid-2025.

In 2022 Amazon had signed contracts with the other three launch companies, with ULA getting 38 Vulcan launches (in addition to 9 already signed for its Atlas-5), Arianespace getting 18 Ariane-6 launches, and Blue Origin getting 12 New Glenn launches.

The problem however is that, except for the Atlas-5, none of these rockets has yet completed its first flight. Since Amazon’s FCC license requires it to get half of its constellation of 3,200+ satellites into orbit by 2026 or face penalties, the uncertainty of these rockets has probably forced Amazon management to consider SpaceX, despite likely hostility to such a deal from Jeff Bezos (owner of Blue Origin and founder of Amazon).

Amazon management also probably decided to sign this deal because of a lawsuit filed in September 2023 by company stockholders, accusing the management of neglience because it never even considered SpaceX in earlier contract negotiations while giving favoritism to Bezos’s company Blue Origin. At that time Amazon had already paid these launch companies about $1.7 billion, with Blue Origin getting $585 million, though not one rocket has yet launched, with Blue Origin showing no evidence that a launch coming anytime soon.

The impression of a conflict of interest by Amazon’s board of directors appeared very obvious. This new SpaceX contract weakens that accusation.

More important the deal will help Amazon actually get its satellites into orbit. It appears that reality is finally biting at Amazon, and its management has realized that the three companies they have been relying on might not be up to the job (especially Blue Origin).

Sunspot update: The Sun continues to prove that solar scientists understand nothing

3:49 pm

With today’s monthly update from NOAA of its graph tracking the number of sunspots on the Sun’s Earth-facing hemisphere, we find that the Sun continues to confound the experts. As I do every month, I have posted this graph below, with additional details to provide the larger context.

In November the sunspot count rose slightly, but remained well below the highs that had occurred through most of the first half of 2023. Yet, despite that continuing reduction in the number of sunspots, the overall amount of activity remains above the prediction of some scientists, and below the prediction of other scientists.

Minnesota school brings sanity back to the classroom by banning smart phones

1:35 pm

The smart phone: Bad for kids
The smart phone: Proven very bad for kids

Making schools productive again: A Minnesota middle school has found that banning smart phones from all students during the school day has improved behavior both in and out of the classroom while improving the learning and social environment.

“I believe (the ban) is game-changing and will have lasting impacts on our students for years to come,” Maple Grove Middle School Principal Patrick Smith told WCCO. “There was no cross-the-table conversations, there was no interaction in the hallways,” he said. “And let’s be real, with these devices, our students – especially our teenagers – there’s a lot of drama that comes from social media, and a lot of conflict that comes from it.”

Last year, school officials banned student cell phone use for the entire school day, from 8:10 a.m. to 2:40 p.m., following a variety of issues at the school tied to the devices. “We have a culture and climate concern. We see issues that kids are getting on their phones through interactions of bullying, of setting up fights, just the gambit of a lot of the negative things kids are going back and forth on social media,” Smith said on the Chad Hartman Show, adding that the distraction from learning was also a major concern.

After a year school officials and parents are enthused by the results. Not only has the social atmosphere improved at the school, parents are reporting improvements in learning in their kids.

None of this is a surprise. » Read more
