China and Luxembourg sign space cooperation agreement

5:29 pm

The new colonial movement: China and Luxembourg have signed a space cooperation agreement that includes the creation of a research facility in Luxembourg.

The press release doesn’t really provide any real specifics, but if I had to guess based on what’s there I would say that the two countries are probably trying to make a partnership that will give them more clout in establishing their ownership of territory in space. Or to put it another way, each probably now agrees that they will honor the claims and regulatory rules of the other.

Titan’s liquid hydrocarbon seas have a global sea level

12:48 pm

New research using Cassini data has revealed that the liquid hydrocarbon oceans of Saturn’s moon Titan have a global sea level, with some small lakes perched at higher elevations.

The new study suggests that elevation is important because Titan’s liquid bodies appear to be connected under the surface in something akin to an aquifer system at Earth. Hydrocarbons appear to be flowing underneath Titan’s surface similar to the way water flows through underground porous rock or gravel on Earth, so that nearby lakes communicate with each other and share a common liquid level.

NASA’ safety panel illustrates the impossibility of exploration by NASA

12:36 pm

Last week NASA’s Aerospace Safety Advisory Panel (ASAP) issued its 2017 report [pdf], detailing the areas it has concerns for human safety in all of NASA’s programs. Not surprisingly, the report raised big issues about SpaceX, suggesting its manned launch schedule was questionable and that there were great risks using the Falcon 9 rocket as presently designed.

ASAP was especially concerned with the issues with the Falcon 9 COPV helium tanks and how they were connected with the September 2016 launchpad explosion, as well as SpaceX’s approach to fueling the rocket. Below is a screen capture of the report’s pertinent section on this.

ASAP SpaceX concerns

The report complements NASA and SpaceX for looking at a new design for the COPV helium tanks, but also appears quite willing to force endless delays in order to make sure the issue here is completely understood, even though this is likely impossible for years more.

ASAP also raises once again its reservations about SpaceX’s method of fueling the Falcon 9, which would have them fill the tanks after the astronauts are on board so that the fuel can be kept cold and dense to maximize performance. This issue I find very silly. The present accepted approach is to fill the tanks, then board the astronauts. SpaceX wants to board the astronauts, then fill the tanks. Either way, the astronauts will be in a rocket with tons of volatile fuel and oxidizer. I really do not see why it makes that much of a difference, especially with SpaceX building a successful track record using its approach with each successful commercial launch. They did 18 last year alone.

Below the fold is a screen capture of the report’s entire summary, with some sections highlighted by me.

Awan and cohorts made many “unauthorized” accesses to Congressional accounts

10:29 am

A House report has found that Pakistani IT specialist Imran Awan and cohorts made many “unauthorized” accesses to Congressional accounts, and worked to hide those accesses.

The presentation, written by the House’s Office of the Inspector General, reported under the bold heading “UNAUTHORIZED ACCESS” that “5 shared employee system administrators have collectively logged into 15 member offices and the Democratic Caucus although they were not employed by the offices they accessed.” It found indications that a House “server is being used for nefarious purposes and elevated the risk that individuals could be reading and/or removing information” and “could be used to store documents taken from other offices.” The server was that of the House Democratic Caucus, a sister group of the DNC that was run at the time by then-Rep. Xavier Becerra.

The aides named are Imran Awan, his wife Hina Alvi, his brothers Abid and Jamal, and his friend Rao Abbas, Pakistani-born aides whose lives are filled with reason for concern. Abid’s Ukranian wife Natalia Sova and Haseeb Rana were also involved in the Awans’ activities but departed the House payroll prior to the investigation.

One systems administrator “logged into a member’s office two months after he was terminated from that office,” the investigative summary says.

The report also found that the Democrat leadership, which would have then been Congresswoman Debbie Wasserman Schultz (D-Florida), poo-pooed the issue to its members, which then led 44 Democrats to not take actions to protect their systems, even after their accounts had been accessed improperly.

This scandal not only suggests a breach of American security by Pakistan agents, working for the Democrats in the House, but suggests that those Democrats either were fools, were being blackmailed to cooperate, or were traitors working in partnership with those foreign agents.

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:

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.

A movie of Jupiter’s south polar region

12:40 pm

Cool movie time! Using Juno images, a citizen scientist has created a short movie showing two complete rotations of Jupiter’s south polar regions. I have embedded the movie below the fold. It is definitely worth watching. As he notes,

Due to Jupiter’s low axial tilt we never see more than roughly one half of the area around the poles in sunlight at any given time. However, it is interesting to see what Jupiter’s polar regions would look like if things were different and a big area around the poles was illuminated. This rotation movie shows what Jupiter’s south polar region would look like near the time of southern summer solstice if Jupiter’s axial tilt was much greater than it is, i.e. comparable to Saturn’s axial tilt.

He also notes the puzzling fact that, though Jupiter and Saturn are both gas giants, unlike Saturn Jupiter does not have a vortex at its poles. In fact, he points out how none of Jupiter’s storms are centered at the pole. Why one gas giant should have such pole-centered vortexes while another does not is a big mystery that illustrates how very little we know about planetary formation and evolution.

The two rotations also do not show any changes in the storms, not because they aren’t changing but because the images used were taken over too short a time span to show this.

VSS Unity completes 7th glide test

7:17 pm

Capitalism in space: Virgin Galactic’s Unity suborbital spaceship completed 7th glide test today.

I must admit that I am only reporting this because I feel obligated to. This was their first flight in five months, and they have still not done a powered flight. I cannot get excited about Virgin Galactic and SpaceshipTwo until I actually see them reach space, something they have still not accomplished after fourteen years of development.

Rocket Lab announces January launch window

7:06 pm

Capitalism in space: Rocket Lab has announced that it will attempt the second test launch of its Electron rocket during a nine day launch window beginning on January 20.

Bad weather and technical issues prevented this launch in December. Meanwhile, Japan is also planning a test launch in January of its only smallsat rocket, the SS-520. The Japanese entry is a demo mission designed and built by that country’s space agency, while Rocket Lab is entirely private. Both however provide more evidence that 2018 will be a booming year (no pun intended) for rockets.

India and ULA complete first launches in 2018

6:41 pm

The competition heats up: In what looks like the beginning of what might be the most active launch year in almost three decades, India and ULA today each successfully completed their first launches of 2018.

ULA’s Delta 4 rocket launched a U.S. reconnaissance satellite, while India’s PSLV rocket placed in orbit 31 satellites, 30 of which were smallsats. For India, this was their first launch since an August PSLV launch failed when the rocket fairing did not release.

Update: I just discovered that China launched its second rocket yesterday, placing it in a tie with U.S. for most launches and ahead of everyone else.

Exposed mid-latitude ice deposits found on Mars

4:26 pm

Scientists have discovered eight locations on Mars where underground ice appears to be exposed on cliff faces

The scarps directly expose bright glimpses into vast underground ice previously detected with spectrometers on NASA’s Mars Odyssey orbiter, with ground-penetrating radar instruments on MRO and on the European Space Agency’s Mars Express orbiter, and with observations of fresh impact craters that uncover subsurface ice. NASA sent the Phoenix lander to Mars in response to the Odyssey findings; in 2008, the Phoenix mission confirmed and analyzed the buried water ice at 68 degrees north latitude, about one-third of the way to the pole from the northernmost of the eight scarp sites.

The important thing about this discovery is that, though we have known for several years that water ice exists underground in the Martian mid-latitudes, this is the first time we have identified specific places there it is exposed and accessible.

Unfortunately, the press release does not provide the specific eight locations, except for the one image, which is located in the southern hemisphere in a region called Promethei Terra, far from areas that have been studied much more extensively. I will do some digging to see if I can identify the other seven locations.

An illicit visit to two abandoned Soviet space shuttles

6:01 pm

An evening pause: Hat tip John Harman. This video has been around for awhile, but I hadn’t ever actually watched it until now. What it shows is very cool, but sad in so many ways. As a government project the whole Soviet space shuttle program was generally a dead end waste of resources (as was our own shuttle). Yet, it was possibly one of Soviet Russia’s greatest technological achievements — which they have allowed to rot away in these abandoned hangers, rather than opening them up for their citizens to see and admire and learn from.

NASA funds a cubesat-sized ultra-violet telescope

2:50 pm

NASA has funded a cubesat-based ultra-violet telescope to launch in 2021.

SPARCS is a CubeSat built of six cubical units, each about four inches on a side. These are joined to make a spacecraft two units wide by three long in what is termed a 6U spacecraft. Solar power panels extend like wings from one end. “In size and shape, SPARCS most resembles a family-size box of Cheerios,” Shkolnik said.

The spacecraft will contain three major systems — the telescope, the camera, and the operational and science software. Along with Shkolnik, SESE astronomers Paul Scowen, Daniel Jacobs, and Judd Bowman will oversee the development of the telescope and camera, plus the software and the systems engineering to pull it all together. The telescope uses a mirror system with coatings optimized for ultraviolet light. Together with the camera, the system can measure very small changes in the brightness of M dwarf stars to carry out the primary science of the mission.

As I have noted numerous times recently, the space industry is splitting between large manned projects and tiny unmanned ones. While certain unmanned probes will always have to be larger, the ability to build and launch the same capabilities at a smaller size is lowering cost and allowing more probes to be launched.

A lava tube entrance near the Moon’s north pole?

2:21 pm

Philolaus Crater near lunar north pole

In reviewing Lunar Reconnaissance Orbiter data scientists think they have discovered several skylight entrances into a lava tube that is located near the Moon’s north pole.

The new pits were identified on the northeastern floor of Philolaus Crater, a large, 43 mile (70 km)-diameter impact crater located at 72.1oN, 32.4oW, about 340 miles (550 km) from the North Pole of the Moon, on the lunar near side. The pits appear as small rimless depressions, typically 50 to 100 feet across (15 to 30 meters), with completely shadowed interiors. The pits are located along sections of winding channels, known on the Moon as “sinuous rilles,” that crisscross the floor of Philolaus Crater. Lunar sinuous rilles are generally thought to be collapsed, or partially collapsed, lava tubes, underground tunnels that were once streams of flowing lava.

“The highest resolution images available for Philolaus Crater do not allow the pits to be identified as lava tube skylights with 100 percent certainty, but we are looking at good candidates considering simultaneously their size, shape, lighting conditions and geologic setting” says Pascal Lee, planetary scientist at the SETI Institute and the Mars Institute who made the new finding at NASA’s Ames Research Center in Silicon Valley.

…Prior to this discovery, over 200 pits had been found on the Moon by other researchers, with many identified as likely skylights leading to underground lava tubes associated with similar sinuous rilles. However, today’s announcement represents the first published report of possible lava tube skylights in the Moon’s polar regions.

The floor of the crater as a lot of rilles, and a close look at that crater floor reveals to me a lot of possible sky light entrances, more than indicated by the images at the llink. (Go here, click on projections and pick “Orthographic (North Pole).” Then zoom in on the crater indicated by the yellow X in my image on the right above.)

The key here is that caves or lava tubes provide a good place to cheaply and quickly establish a lunar colony. While it is suspected that water might survive in permanently shadowed regions near the poles, up until now no one had found any good underground locations there. If this suspected skylight entrances prove true, this crater then becomes prime real estate on the Moon.
