More problems at Boeing, this time with military aircraft

10:11 am

In this article about Israel’s desire to obtain the new KC-46A airplane tankers being built by Boeing for the Air Force, it is revealed that Boeing has had numerous disturbing manufacturing problems on this particular plane.

Earlier in 2019 the U.S. air force resumed, after a two-month delay, accepting new KC-46As. That two-month delay was because of FOD (Foreign Object Debris), including tools and other metal objects, still showing up in various parts of the aircraft. This indicated a serious lapse in the management of assembly and quality control while producing these aircraft. By March, after nearly a month of effort to check out aircraft nearly ready for delivery as well as factory inspection procedures, the air force agreed to begin accepting KC-46s once more. Deliveries continued despite the recently discovered cargo lock (unreliable cargo tie down latches) problem. The Americans are now concerned about Boeing, the manufacturer while also needing the KC-46As as soon as possible. This is the same firm that is having worse problems with its new 737 Max commercial airliner.

In mid-2019 Boeing planned to deliver 36 KC-46As by the end of 2019 and later expected to meet that goal even though only 19 had been delivered by early September. At the end of the year the goal of 36 was missed but Boeing did fix the cargo lock problem and this allowed cargo to again be carried. There is one problem left with the accuracy of the remote viewing system used by the 46A boom operator. That does not prevent operation of the aircraft, just slows down refueling in some cases.

Boeing has had problems with its 737-Max commercial jet (now grounded), with the construction of the Space Launch System (SLS) for NASA (a decade behind schedule and billions over budget), and with its manned Starliner space capsule. The list of issues above for the KC-46A is equally troubling, and indicates that the management and quality control problems indicated by the other projects might very well be systemic to the entire company. Not good, not good at all.

Update on Dream Chaser

9:54 am

Link here. According to Sierra Nevada, the company that is building this mini-shuttle cargo ship, they are on track to launch next year. They are also aggressively working on a Dream Chaser version that would be able to transport humans to space.

SNC has “never stopped working” on the crewed version of Dream Chaser, Lindsey said. While the company’s focus right now is getting the cargo version ready for its first flight on a United Launch Alliance (ULA) Vulcan-Centaur rocket next year, the first crewed flight “absolutely” will take place within 5 years.

“There’s interest, not necessarily from NASA, but other customers” that Lindsey expects to grow once the cargo version is flying. SNC will offer either a “taxi model” where it supplies the crew to fly it, or a “rental car model” where the customer provides the crew. It will be up to the customer to decide.

If they can get this spacecraft operational, they will join SpaceX as a leader in the reusability market, having built a ship that can be flown repeatedly on profit-making missions. In fact, it appears that the entire private American effort to get humans into space is aggressively shifting towards full reusability. SpaceX has got the first stage solved, and is also now routinely reusing its cargo Dragon capsules. It is also working to make both the upper stage (Starship) and manned capsules (crew Dragon) reusable. Sierra Nevada is in turn working on the manned spacecraft with Dream Chaser. Similarly, Blue Origin says the first stage of its New Glenn rocket will be reusable.

Those companies and nations that ignore this development (such as the Europeans Space Agency and Russia) will find themselves left far behind. Reusablity of rockets has been proven, and it lowers the cost to get to space so radically that without it you cannot compete.

House committee approves bill coordinating the government’s space weather work

9:38 am

The House science, space, and technology committee has approved a new bill that establishes a coordinating structure for the many government agencies involved in observing and research space weather, the material that the Sun throws at us that can affect electrical grids and communications.

A similar bill has been approved by the Senate commerce committee, but with several important differences, the most important of which is likely this provision in the House bill:

The provision requires NOAA to establish a commercial space weather data pilot program within one year of the bill’s enactment. Through that program, NOAA is to offer to enter into contracts with “one or more entities in the commercial space weather sector” to provide data that meets standards and specifications that NOAA, in consultation with the Secretary of Defense, must publish within 18 months of enactment. The data may be ground-based, ocean-based, air-based, or space-based. NOAA “may offer” to award “at least one” competitively-bid contract within 12 months of when the Integrated Strategy required in the bill, as reviewed by the National Academies, is transmitted to Congress. “If” one or more contract is awarded, NOAA is to assess the value of the pilot program and report to Congress within 4 years of enactment.

The goal of this provision is to shift construction of new space weather facilities, including satellites, from the government to private industry. Like NASA and the Defense Department, NOAA in recent decades has generally done a poor job of building satellites cheaply and quickly to maintain its in-space monitoring network. The hope is that by depending on the growing private sector, the agency can get its satellites replaced more effectively, while also energizing the space private sector.

The Senate and House bills both have only passed through committee. We shall see if the Senate agrees to add this provision to its version of the bill.

Arecibo shut temporarily due to earthquakes

9:24 am

The Arecibo Observatory in Puerto Rico has suspended all operations temporarily because of the swarm of earthquakes that have hit the island in the past two weeks.

The strongest of those quakes was a 6.4 temblor early in the morning of Tuesday (Jan. 7). An initial survey conducted by drone after that event found no damage to the massive radio dish or the equipment above it, an Arecibo Observatory representative said here at the 235th meeting of the American Astronomical Society on Tuesday (Jan. 7).

However, safety protocols mean that observatory personnel can’t examine the dish or its accessories until the ground stops shaking, and it’s difficult to predict when that will happen.

The observatory was about to embark on a yearlong refitting to repair damage caused by Hurricane Maria in 2017. They have set January 10th as a tentative reopen date.

Probe to visit 8 asteroids, not 7

12:11 am

Scientists developing the Lucy mission to visit seven Trojan asteroids that share an orbit with Jupiter have found an eighth satellite they will also be able to visit.

This first-ever mission to the Trojans was already going to break records by visiting seven asteroids during a single mission. Now, using data from the Hubble Space Telescope (HST), the Lucy team discovered that the first Trojan target, Eurybates, has a satellite. This discovery provides an additional object for Lucy to study.

“If I had to bet that one of our destinations had a satellite, it would have been this one,” said SwRI’s Hal Levison, principal investigator of the mission. “Eurybates is considered the largest remnant of a giant collision that occurred billions of years ago. Simulations show that asteroid collisions like the one that made Eurybates and its family often produce small satellites.”

The mission is targeting a 2021 launch date.

UK parliament approves Brexit deal at last

11:10 pm

Prime Minister Boris Johnson’s deal to leave the European Union on January 31, 2020 was finally approved today by Parliament 330 to 231.

Not so fast. The deal calls for eleven months of negotiations on the various issues involved for the exit, and the head of the EU was in London calling for an endless extension of that deadline.

The new president of the European Commission Ursula von der Leyen came to London yesterday for her first face-to-face talks with Mr Johnson. She was accompanied by the EU’s chief Brexit negotiator Michel Barnier who will now lead trade discussions on behalf of the bloc after managing the divorce stage.

…During a speech at the London School of Economics, where she spent a year in hiding as a student in the late 1970s after becoming a target of the left-wing terrorist Baader-Meinhof gang, she said that a full deal would not be achievable in just 11 months. She said: ‘Without an extension of the transition period beyond 2020 you cannot expect to agree on every single aspect of our new partnership. We will have to prioritise.’

Mr Barnier echoed a similar sentiment in a speech in Stockholm today as he said: ‘We are ready to do our best and to do the maximum in the 11 months to secure a basic agreement with the UK, but we will need more time to agree on each and every point of this political declaration.’

This game by these elitists is getting very tiresome. Johnson responded by saying that there would be no extensions.

Senate considers rules change permitting dismissal of House impeachment lacking submission

2:46 pm

The Republican Senate leadership is considering a rules change that would allow them to dismiss the House impeachment of Donald Trump if the articles of impeachment are not delivered in a timely manner.

The resolution would give the House 25 days to send articles of impeachment over to the Senate. After that, a senator could offer a motion to dismiss “with prejudice for failure by the House of Representatives to prosecute such articles” with a simple majority vote, according to Hawley’s proposal.

I should note that the Senate is entirely within its rights to do this. The Constitution does not require the delivery of those articles in any specific manner, as has become customary. All it says, literally, is that the House “shall have the sole power of impeachment,” and that “the Senate shall have the sole power to try all impeachments.” That’s it. If the Senate wishes to dismiss an impeachment that the House passed but didn’t deliver officially, it can do so.

This Democratic clown show and attempt to overturn an legal election they lost is about to end quite embarrassingly for these Democrats. Hopefully however the embarrassment will be multiplied many fold come November, with a wipe-out landslide for Trump and the Republicans. It is long past time to clean house in the Democratic Party.

First SLS core stage completed and ready for final testing

2:12 pm

After sixteen years of development, slowed by politics and a confused management at NASA, the first core stage of NASA’s SLS rocket is finally completed and ready for shipping to the Stennis Space Center in Mississippi for its final full test.

The heart of NASA’s first flight-ready Space Launch System heavy-lift rocket emerged from its factory in New Orleans Wednesday morning for a barge trip to the Stennis Space Center in Mississippi for an eight-minute test-firing of its space shuttle-era hydrogen-fueled engines.

The 212-foot-long (64.6-meter), 27.6-foot-wide (8.4-meter) core stage of the Space Launch System rolled out of its factory at the Michoud Assembly Facility, signaling a significant, but long-delayed milestone in the SLS program’s eight-year history. Teams loaded the core stage into NASA’s Pegasus barge to be ferried on a half-day journey to the Stennis Space Center in Mississippi.

The link has a lot of cool images of the stage. You can also find more cool images and videos of the core stage’s unveiling yesterday here.

Whether this stage will pass that eight-minute test remains unknown. And if it does, it also remains unknown whether it will be ready to fly in November 2020, sending an unmanned Orion capsule around the Moon. Either way, the cost to build that SLS rocket is approaching $25 billion, a cost that only includes two flights, one unmanned.

We could have bought a lot of Falcon Heavies for that price, and be heading for the Moon right now had we done so.

Pedestal craters in the Martian northern lowlands?

1:59 pm

Pedestal craters on Mars?
Click for full image.

Cool image time! The photo on the right, cropped and reduced to post here, shows a cluster of really strange mesas, craters, and pits, located in Utopia Planitia, the largest and deepest plain of Mars’ northern lowlands where an intermittent ocean might have once existed.

The image was taken on October 26, 2019 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) as part of its regular image-taking program. In this case it was dubbed a “terrain sample” image, meaning that it was not specifically requested by any researcher, but was taken because they need to use the camera regularly to maintain its temperature, and thus sometime produce images over previously untouched areas, not knowing what they will find, as part of that maintenance schedule.

In this case the terrain sampled is especially intriguing. Are the upraised depressions what are called pedestal craters, created when the impact landed on what was once an icy plain, which subsequently sublimated away to leave the crater sitting high above the surrounding flats? Maybe, but this location is at 23 degrees north latitude, and research has generally found these pedestal craters at latitudes higher than 30 degrees.

Moreover, that many of these upraised depressions are not circular suggests that their formation was not impact related.

Other mysteries: Why are all the ridgelines bright? What caused the parallel white streaks to the east and west of some mesas? And if these are impact craters, why are some distorted?

If this region was once the seabed of an intermittent ocean, this fact might explain the features. Then again, it is more likely that this lowland area was once covered in ice in the far past, when the planet’s tilt was greater and the lower latitudes were actually colder than the polar regions, and thus allowed ice to build up in those lower latitudes. We might therefore be seeing the end result of an erosion/sublimation process as that ice disappeared when Mars’ inclination shifted.

Lots of questions, and no answers.

Iran misses military targets, kill passenger jet instead

11:09 am

How typical for a terrorist nation: Iran, in its claimed revenge for the U.S. strike that killed terrorist Qassem Soleimani, failed entirely with its missile barrage to kill even one American or inflict any significant damage on any military target, managed however to shoot down a Ukrainian passenger jet, killing 176 innocent civilians.

More here.

There are also indications that the missile barrage was designed to avoid inflicting serious harm to U.S. facilities or troops, suggesting that the Iranians were merely doing it for propaganda purposes. With the mistaken murder of almost two hundred civilians however they have also failed in achieving that propaganda goal. Instead, they have once again shown their willingness to kill indiscriminately in order to maintain their power.

Meanwhile, here in the U.S. the Trump action in killing Soleimani has done a wonderful job of revealing the traitorous perspectives of many Democrats and the mainstream press. They are more concerned for Iran and the fate of this murderous thug then they are for the United States, freedom, or democracy.

More libel lawsuits initiated by Covington student

9:26 pm

A new libel lawsuit has been filed by Covington student Nick Sandmann, this time against former CNN host Reza Aslan.

The suit, demanding $135,000 in damages, is for a tweet Aslan sent out showing Sandmann with the comment, “Have you ever seen a more punchable face than this kid’s?” Moreover,

According to PJ Media the suit names a variety of public figures including “Ana Navarro, Sen. Elizabeth Warren (D-Mass.), Maggie Haberman, and Kathy Griffin.” PJ Media also reports that “According to the lawsuit, the tweet calling Sandmann’s face ‘punchable’ further spread the false narrative that the Covington Catholic boys had aggressively insulted the Native American man, when that was not the case.”

The more the merrier. These leftist mainstream news reporters and politicians have been very willing to spread lies and slanders, and when caught have refused to do anything to fix the problem. The solution then is to bankrupt them in the courts.
