U.S. 2020 Mars rover faces delays

9:26 pm

A new inspector general report has pinpointed a number of issues that could cause a delay in the 2020 launch of the next American Mars rover mission.

The biggest risk to the mission, according to NASA OIG, is the sampling system that will be used to collect and store samples of Martian rock and soil that a future mission will gather for return to Earth. That system, an essential part of the mission, has several key technologies that are less mature than planned at this phase of the mission’s development. “The immaturity of the critical technologies related to the Sampling System is concerning because, according to Mars 2020 Project managers, the Sampling System is the rover’s most complex new development component with delays likely to eat into the Project’s schedule reserve and, in the worst case scenario, could delay launch,” OIG stated.

I find it puzzling that the sampling system is an issue. This rover is essentially based on Curiosity, which has very sophisticated equipment for grabbing and even storing samples for periods of time. I don’t understand why such systems could not be quickly revised for future retrieval.

Nonetheless, there are other problems however.

Two instruments on the Mars 2020 mission have also suffered problems. One, called MOXIE, is designed to test the ability to generate oxygen on Mars, saw its estimated increase by more than 50 percent during its development. NASA has taken steps to reduce some of that cost growth by eliminating development of an engineering model and skipping further design improvements in one element of MOXIE.

Another instrument designed to study atmospheric conditions on Mars, MEDA, has suffered delays because of a “financial reorganization” by its developer, Spain’s National Institute for Aerospace Technology. OIG concluded in its report that MEDA is unlikely to be ready for delivery to NASA in April 2018, as currently scheduled. That could require adding MEDA to the rover later in the overall assembly process, or flying the mission without the instrument.

One of the reasons the Obama administration decided to make this 2020 rover mission a reboot of Curiosity was to save cost and development time. Thus, it does not speak well for NASA’s planetary program that they are having these problems.

Japanese experiment to remove space junk fails

7:22 pm

A Japanese experiment designed to test technology for removing space junk and flown on that country’s most recent cargo ship to ISS has failed to deploy its tether as planned.

The system, designed by the Japanese space agency (JAXA) and a fishing net company, should have unfurled a 700-meter (2,300 ft) tether from a space station resupply vehicle that was returning to Earth. According to JAXA scientists, however, the system appears to have faltered.

This only adds another technical failure to a string of technical failures by Japanese spacecraft. And even though the cargo ship operated as planned, its launch was delayed when engineers discovered a leak during testing. Overall, it increasingly appears that Japan’s space program has the same kind of quality control problems as Russia.

Some radioisotope dating might be overestimating the age of samples

7:11 pm

The uncertainty of science: New research suggests the radioisotope dating that scientists use has been overestimating the age of many samples.

The article does not indicate if this overestimate applies to all radioisotope dating or just to the strontium-86/rubidium-87 dating methods mentioned. Nor does the article detail how much of an overestimate the scientists have measured. Depending on these factors the difference — and its influence on scientific results — could be relatively small, or quite large.

Gorsuch picked by Trump for Supreme Court

6:38 pm

President Trump tonight named Neil Gorsuch as his pick to replace Antonin Scalia on the Supreme Court.

My fear that Trump would go for the more moderate Thomas Hardiman has proven unfounded. Instead, this more conservative choice once again suggests that Trump is shifting increasingly to the right.

In fact, I think the insane and insulting attacks brought against Trump by the left have actually served to make him more conservative. As Rush Limbaugh noted today,

Would you like an illustration of what I mean by Donald Trump not being ideological and how it’s a problem? He understands he has opposition. How could he not? (chuckles) I mean, I’m sure he knows that he’s got opposition. Don’t misunderstand me, now. And I’m sure that he may have had his eyes opened about some of these people. In his mind, they’re Democrats. Liberal, conservative, that’s not in his lexicon, folks. I’m not offering this as a criticism. It’s just a truth. It’s something that, if you want to understand Trump, then there’s no better deconstructor of Trump and explainer of Trump who’s not in the inner circle than me.

All during the campaign I did my best to explain to everybody — leftists, media, conservative, Republicans, Never Trumpers — who Trump is, why Trump is, why Trump was winning, who Trump’s supporters are. And the thing that I kept saying is, “He’s not ideological.” So he knows he’s got opposition, he knows Democrats, and he’s probably had his eyes opened here. I’m sure that over the course of his life some of these people now calling him names trying to destroy him have been his friends. So his eyes are no doubt opened. I don’t doubt that.

When Trump first announced his candidacy, everything he did and said at that time fit with Limbaugh’s analysis, except that at the time I think Trump was much more middle of the road. I think he truly believed his liberal background working closely with Democrats would make them treat him decently. Instead, they have come at him guns blazing, calling him the worst sort of names, making the most vile accusations against him, and even attacking his family and his children.

The result? Trump has, as Limbaugh notes, had “his eyes opened.” He might not be a philosophical conservative, but more and more it appears that he recognizes the corrupt hate coming from the left, and is less and less inclined to give them an inch. Instead, he moves rightward. I also think this is the same pattern we are seeing nationwide among voters.

Right now the Democrats in the Senate look like they are planning to copy the strategy to try to block Trump’s Cabinet appointees used by Texas and Wisconsin Democrats in 2003 and 2011 respectively.

This is not the first time Democrats have blocked a Republican majority from proceeding by refusing to take their seats and thus denying Republicans a quorum. In 2003, 11 Democrats in the Texas House of Representatives literally fled the state for weeks in order to prevent a redistricting plan favored by Republicans. Eventually, one of them returned and the redistricting plan was passed. More recently, in 2011, Wisconsin Democrats fled to Illinois for three weeks to avoid a vote on Republican Gov. Scott Walker’s budget bill because of provisions that were opposed by Wisconsin unions. However, the GOP-controlled legislature defeated the Democrats’ maneuvers by separating these bills from the budget and passing them separately.

In both cases, the Democrats not only failed to win, but their actions caused the voters to move to the right, voting in more Republicans and significantly reducing Democratic influence in both these states. With Wisconsin the result has been the shift of that state from a blue to a red state.

They say that Einstein called insanity doing the same thing over and over again and expecting a different result. I think this nicely defines the Democratic Party these days.

“We need to start killing people.”

4:27 pm

This story has been making the rounds, but I held off posting it because I wanted some confirmation that it was real. It is. At a anti-Trump rally this weekend in Seattle one speaker made it very clear what she wanted:

“F**k white supremacy. F**k the U.S. empire” the speaker attacks capitalism. “You know what America thrives off of? Capitalism,” the speaker says, adding, “We use our mother=f**king, f**king black and brown bodies to live and survive while white people own f**king properties after that.” But the speaker has a solution for this problem, “So you know what we need to do? We need to start giving f**king money.” The rant continues, “White people, give your f**king money, your f**king house, your f**king property, we need it f**king all. You need to reparate black and indigenous people right now.”

A minute or so later, the speaker takes it up a notch saying, “And we need to start killing people. First off, we need to start killing the White House. The White House must die.” [emphasis mine]

The worst part? The speaker claimed she was a preschool teacher who intended to “f**king radicalize mother-f**king four year olds and five year olds.” Imagine her as the teacher of your toddler. Every other word is a curse word, and the words in-between are filled with hate.

After the Tucson shooting in 2011, the left made a big deal about the terrible incivility of the right. Obama even came to Tucson and gave a speech about the need for civility. The trouble is, the left never intended to rein in its own incivility. That crudeness to them is perfectly okay. Their goal was merely to shut down any opposition. Now they are moving to escalate their own crudeness towards violence, because no opposition to them can be tolerated.

And people wonder why I use the word fascism to describe this behavior.

A review of 2016 launches

8:53 am

Link here. The report essentially confirms my own conclusions that I posted several weeks ago. This new report however also looks at total payloads, something I had not done, and finds that though there was a decline in 2016 in the number of satellites launched, they expect that trend to end in 2017 with the continued growth in the smallsat industry.

India to launch spare GPS satellite because of single satellite failure

8:42 am

Because of the failure of the atomic clocks on one of its GPS satellites have failed, India now plans to launch one of their spare satellites to increase the system’s redundancy.

The article does not say whether they will make any changes to the clocks on the spare satellite, which are the same as the failed clocks on the Indian satellite and were all built by the same European company that built the clocks on Europe’s Galileo GPS satellites that are also failing.

Trump fires acting AG for refusing to defend his executive order on immigration

8:05 pm

At last! President Trump this evening fired the acting attorney general because of her announcement earlier today saying that the Justice Department would not defend in court his executive order on immigration.

The Trump announcement:

The acting Attorney General, Sally Yates, has betrayed the Department of Justice by refusing to enforce a legal order designed to protect the citizens of the United States. This order was approved as to form and legality by the Department of Justice Office of Legal Counsel.

Ms. Yates is an Obama Administration appointee who is weak on borders and very weak on illegal immigration.

It is time to get serious about protecting our country. Calling for tougher vetting for individuals travelling from seven dangerous places is not extreme. It is reasonable and necessary to protect our country.

Tonight, President Trump relieved Ms. Yates of her duties and subsequently named Dana Boente, U.S. Attorney for the Eastern District of Virginia, to serve as Acting Attorney General until Senator Jeff Sessions is finally confirmed by the Senate, where he is being wrongly held up by Democrat senators for strictly political reasons.

For more than a quarter century I have watched Republican leaders back down the instant a Democrat whined at them. Every. single. time. This time is different. Trump is not a fearful politician. He is a businessmen, an executive, and someone who expects his employees to support his actions. My first reaction when I read Yates statement earlier today was, “Fire her!” I then laughed because I haven’t seen that common sense reaction from a Republican for decades. I have seen it now.

There is still no guarantee that Trump’s policies or actions are going to be very conservative. For example, the one person out of five listed for possible Supreme Court nominee that I have found very questionable has now risen to the top of the list. Yuch. Nonetheless, Trump seems determined to make significant and positive changes in a number of areas, from immigration to environmental policy and administration. If he only does these things, he will have accomplished much.

Update: State Department officials are putting together a memorandum that will announce their opposition to President Trump’s executive order on immigration. I wonder how long these individuals will survive working for Trump after they do this.

New close-ups of Saturn’s rings

1:00 pm

New close-ups of Saturn’s rings, taken during one of Cassini’s recent ring-grazing orbits, have now been released.

They have released four different images, all at a higher resolution than any previous image. Even so, the individual particles in the rings remain unresolved. Instead, many different intriguing patterns are observed, once again suggesting that though the rings are made of many solid particles, they behave as a unit more like a liquid.
