1 in 10 graduates of DC schools rarely if ever attended school

10:13 am

The coming dark age: An investigation into the Washington DC school system has found a great deal of corruption in grading, including the fact that 1 in 10 graduates receive diplomas even though they rarely if ever attend school.

The report, commissioned by the Office of the State Superintendent of Education, portrays a school system riddled by student absenteeism and teachers who feel pressured to push chronically absent high school seniors across the graduation stage regardless of whether they earned their diplomas.

The review saved some of its sharpest criticism for Ballou High School, which has been engulfed in controversy amid a graduation scandal. The report found that the school’s administrators told teachers that a high percentage of their students were expected to pass and encouraged them to provide makeup work and extra credit to students, no matter how much school they missed. Teachers received little training in a new grading system, and their annual performance reviews hinged in small part on their success in graduating students.

At the same time the report was released, D.C. Public Schools Chancellor Antwan Wilson announced that Ballou Principal Yetunde Reeves, who had been reassigned pending the investigation, will not return to the Southeast Washington school.

While this kind of corruption in public schools is somewhat rampant throughout the country, it has tended to happen far more in cities and states that have been controlled for years by a one-party political machine, which in the U.S. has almost routinely been a Democratic Party machine. The problem isn’t specifically Democrats (though that party’s policies almost routinely make things worse). The problem is the one-party political machine and a reliance on a big government school system.

It would be far better to eliminate the whole public school system, including the taxes it confiscates, and leave it to the families in a local neighborhood to simply band together, hire a teacher, and start a one-room school house for their elementary school kids. These small schools could then band together to form a larger high school, all paid for directly by the parents.

Sounds absurd? It was how the colonies and the U.S. did it for their first few hundred years, until the late 1800s.

I admit that going back to the old way might not work, however. There has also been a dumbing-down of standards nationwide, by everyone. We also no longer have the moral and religious framework that dominated American culture before the mid-20th century that required all parents to get their kids educated.

Virgin Orbit gets another smallsat launch contract

9:55 am

Capitalism in space: Virgin Orbit has signed another launch contract, this time to launch nanosats for a company that provides services to the airline industry.

The flight, which is bound for a low-inclination orbit, is scheduled to occur in early 2019. GomSpace will use the launch to further build out a constellation of small satellites that will use Automatic Dependent Surveillance-Broadcast (ADS-B) and Automatic Identification System (AIS) signal monitoring to track civilian aircraft and ocean-going vessels. This satellite constellation will provide continuous monitoring between 37 degrees North and 37 degrees South, helping provide global situational awareness for air-traffic controllers and shipping companies, and aiding in the identification and location of wayward or missing planes and ships.

The satellites slated for flight on LauncherOne are based closely on the flight-proven hardware used in the successful GOMX-1 and GOMX-3 missions, and will be designed, manufactured, and commissioned by GomSpace. The constellation will be operated by GomSpace’s Mauritius-based customer, Aerial & Maritime Ltd., once in orbit.

This appears to be the fifth launch contract that Virgin Orbit has signed, all with different companies. The recent stories have all suggested commercial launches will begin in 2019. I wonder, considering the company has yet to test fly LauncherOne, its rocket, even once.

There could be many reasons the company is getting so many contracts at this time. They could be offering great deals, with no commitment. They could be farther along in testing than the public knows. They could be fooling the satellite companies (though I doubt this because of the number of companies now signed on). Their other partners, some quite large and powerful, might be exercising clout to get these small smallsat companies to announce a launch contract in order to improve Virgin Orbit’s footprint in the market.

Regardless, we shall find out soon. To start commercial operations by early 2019 they must do some initial flight tests of LauncherOne this year. Time is running out for them to meet this schedule.

Criminal charges filed by Navy against commanders of collision ships

5:33 pm

The Navy today announced that it is filing criminal charges against the commanding officers of the two ships that were involved in collisions earlier this year.

The commanders of the two guided-missile destroyers that were involved in fatal collisions with merchant ships in 2017 will face military criminal charges that include charges of dereliction of duty, hazarding a vessel and negligent homicide, after the two incidents that resulted in the death of 17 sailors total, USNI News has learned.

Cmdr. Bryce Benson, former commander of USS Fitzgerald (DDG-62), along with three Fitzgerald junior officers, face a mix charges that include dereliction of duty, hazarding a vessel and negligent homicide related to the June 18 collision between the ship and ACX Crystal that resulted in the death of seven sailors, according to a statement from the U.S. Navy provided to USNI News.

Cmdr. Alfredo J. Sanchez, former commander of USS John S. McCain (DDG-56), faces similar dereliction of duty, hazarding a vessel and negligent homicide charges for the Aug. 21 collision between the guided-missile destroyer and a chemical tanker off the coast of Singapore that resulted in the death of 10 sailors.

I don’t know whether the military trials will be public (they should be), but if so they will reveal some very interesting details about what was happening on these Navy ships that allowed these collisions to occur.

Trump administration withholds $65 million from UN PLO agency

3:32 pm

The Trump administration today withheld $65 million of a $125 million payment from the UN agency that is supposed to provide aid to Palestinian refugees but has instead been repeatedly found to use it to help the PLO and Hamas in terrorist acts.

In a letter, the State Department notified the U.N. Relief and Works Agency that the U.S. is withholding $65 million of a planned $125 million funding installment. The letter also makes clear that additional U.S. donations will be contingent on major changes by UNRWA, which has been heavily criticized by Israel. “We would like to see some reforms be made,” said State Department spokeswoman Heather Nauert, adding that changes are needed to the way the agency operates and is funded. “This is not aimed at punishing anyone.”

The State Department said it was releasing the rest of the installment — $60 million — to prevent the agency from running out of cash by the end of the month and closing down. The U.S. is UNWRA’s largest donor, supplying nearly 30 percent of its budget. The agency focuses on providing health care, education and social services to Palestinians in the West Bank, Gaza Strip, Jordan, Syria and Lebanon.

Not surprisingly, the PLO is reacting like a five year old, throwing a tantrum, as if it deserves this money no matter what it does.

Mars rover update: January 16, 2018

2:09 pm

Summary: Both rovers have moved little in the past month, Opportunity because it is in a good science location and because it must save energy during the winter and Curiosity because it is in a geological location so good the scientists appear to almost be going ga-ga over it.

Curiosity

null

For the overall context of Curiosity’s travels, see Pinpointing Curiosity’s location in Gale Crater.

In the month since my December 18 update, Curiosity has continued to head south rather than east as originally planned (as indicated by the dotted yellow line in the traverse map to the right). Moreover, the rover has not moved very much, because the science team has decided that there is just too much significant geology in this area on Vera Rubin Ridge, also part of a geological unit they have dubbed the Hematite Unit.

Right now the rover is located at an area they call “Region e,” one of the three patches I have also indicated on the image to the right. From the second update below:

This location is a slight depression with exposed fractured bedrock that appears more “blue” from orbit than the surrounding region. In addition, the orbital evidence and observations from the ground suggest that this location is similar to “Region 10” that we visited just last week, which was shown to have some pretty spectacular small-scale features that were of particular interest to many on the science team. As a result, the team was very excited to reach “Region e” and begin our scientific investigation!

The last few updates on the Curiosity mission update page indicate the excitement the geologists have for this site:

Falcon Heavy static fire test delayed again

12:28 pm

It appears that the first static fire test of the Falcon Heavy has been delayed again from today to later in the week.

There is no word on why the delay, but all indications suggest that they are going through the process step-by-step with great care. As they find things that need addressing they are addressing them, and that only when all issues are resolved will they go forward.

The known ice cliffs on Mars

12:20 pm

Last week there was a big NASA story about the discovery of eight locations on Mars where the evidence strongly suggests that these spots have cliff faces with exposed layers of water ice.

The press release however did not provide an overview about where those eight locations were. Only two locations were given, one for a scarp in Milankovič Crater in the northern hemisphere, and one in an area called Promethei Terra, located in the remote cratered highlands in the southern high-mid-latitudes.

The location of known ice scarps on Mars

After much digging (and some assistance from John Batchelor) I was finally able to obtain the latitudes and longitudes of all 8 locations. All but the scarp in Milankovič Crater crater (shown by the white dot north of Olympus Mons) are located in the white rectangular box shown to the south and east of Hellas Basin, the area with Mars’ lowest elevation. This part of Mars is not well imaged with the high resolution camera on Mars Reconnaissance Orbiter (indicated by the fewer number of red squares in the image), mostly because it appears relatively boring from a distance. Nothing appears to be there for hundreds and hundreds of miles except craters, sand, and sand dunes..

The discovery of these scarps in this area however changes the picture. It suggests that cratered highlands that surround Hellas Basin, including those close to the planet’s equator, could contain similar buried layers of ice. More research is necessary to pin down more locations, especially those closer to the equator where conditions might be more hospitable for a colony.

Moreover, educated readers of Behind the Black have previously noted that because of Hellas Basin’s low elevation the air pressure there is thicker, and therefore the location has some advantages as a potential colony location. These ice scarps raise the value of Hellas Basin considerably, as they suggest that such layers could easily be exposed as you descend into Hellas Basin. If such layers are exposed on the northern flanks of the basin, they would be at latitudes of around 25 to 30 degrees south, a much more friendly latitude for settlement.

Detailed update on Falcon Heavy static fire test set for later today

8:42 am

Link here. The article has a lot of good information not only about the test but about the launchpad and how it will be used in the future.

One take-away that I came off with however came from the picture of the Falcon Heavy on the launchpad. It made me realize how far apart the two side stages sit from the core stages, as the rocket is now reconfigured. My impression of most strap-ons today is that they are placed very close to the core, and they generally have aerodynamic cones that slope away from the core, so that the air is directed away from the space between the stages. Falcon Heavy however has all that space, and the side strap-ons have rounded cones.

I wonder if this is one of the rocket’s most worrisome unknowns, as it travels through Max Q, the period shortly after launch when the stresses created from its speed and the atmosphere are the highest. As designed, a lot of atmosphere will travel between the stages. While this isn’t entirely unique (the shuttle had a somewhat comparable gaps between its various parts), I do wonder.

On the way home

12:48 pm

Diane and I are about to board the airplane here in the Bahamas to return to the U.S. Twas an interesting and pleasant weekend.

Not surprisingly, the TSA were pigs as we left. It turns out that it is forbidden to carry from foreign countries a ham sandwich on the plane to eat. Either that, or they like to steal sandwiches from passengers for their own lunch.

As I said to the TSA agent, “Pigs. This is not the country I was born into.” She then tried to debate politics with me and I said, “No, please, let’s not.”

The real evil here is that the agent was upset that I was honest about having the sandwich. If I had lied and said we had no food with us, they wouldn’t have checked and all would have been fine. The whole setup was designed to make everyone dishonest and liars. If you were honest, you were punished.
