Opportunity enters Perseverance Valley

10:06 am

Opportunity in Perseverance Valley

Just prior to the drop in communications this week because of the Sun’s position between the Earth and Mars, Opportunity was ordered down into Perseverance Valley, where it will sit until the return of full communications.

Opportunity entered Perseverance Valley on the west rim of Endeavour crater. The rover is positioned within the valley where she will spend the solar conjunction period.

Solar conjunction is when the Sun comes between Earth and Mars, which occurs about once every 26 months. During this time, there will be diminished communications to Opportunity. More on solar conjunction here: https://mars.jpl.nasa.gov/allaboutmars/nightsky/solar-conjunction/

Two weeks of commanding have been uploaded to the rover to keep her active during solar conjunction with short communications with the Mars orbiters during the period.

The image on the right, reduced to show here, was taken by the rover’s navigation camera looking back uphill at the crater’s crest and the rover’s tracks in the valley. For the scientists the tracks are important because they reveal what the surface of the valley is like, which will help them determine whether it was formed from flowing water, flowing ice, or wind.

Even more significant, this initial drive into the valley means the science team has decided that either the wheel issues in June were not serious enough to prevent them from making this downhill trip, or the science is important enough that they are willing to risk the rover to get that science.

Growing cucumbers in space

9:48 am

New research growing cucumbers on ISS has found that the roots of these plants grew in the direction of water in weightlessness.

Plant roots grow to find water, according to a process known as hydrotropism. Roots are also influenced by gravity and tend to grow downwards, called gravitropism. To find out whether gravity or water had the greater influence on root growth, investigators grew cucumber plants in the microgravity environment on board the International Space Station. In their experiments, water (or hydrotropism) had more influence in controlling root growth.

“We will be able to utilize roots’ ability to sense moisture gradients for controlling root growth orientation and efficiently growing plants in future space farms,” said Dr. Hideyuki Takahashi, senior author of the New Phytologist study.

You can read the full science paper here.

This might sound obvious, but it isn’t. Past plant growth experiments on Mir and ISS had tended to show that plant roots did not know where to grow in weightlessness, suggesting that they needed gravity to guide the roots to water. Because of this, later experiments in space provided the roots complicated engineering to guide the roots to the water.

This experiment shows that maybe that complex engineering is not necessary, or at least could be simplified a bit. At a minimum it is crucial information engineers will need to design any future gardens for interplanetary spaceships with long term weightlessness.

ISRO’s 104 satellite launched earned India about $7 million

9:23 am

Capitalism in space: India’s space agency ISRO on Wednesday revealed to that country’s parliament that its record-setting 104 satellite launch on June 23 earned about $7 million.

On June 23 this year, PSLV-C38 had launched 712-kg Cartosat-2 satellite along with 30 co-passenger satellites. Of the 30 nano satellites, while one belonged to Noorul Islam University from Tamil Nadu, the rest 29 were from 14 foreign countries. On Wednesday, the government informed the Lok Sabha that the launch of 29 foreign satellites helped Antrix Corporation Ltd (ACL), the commercial and marketing arm of Isro, earn Rs 45 crore (6.1 million euros).

Before the June 23 multiple launch, Isro made the world record when its PSLV C37 launched 104 satellites in one go on February 15 this year. However, the space agency did not reveal how much it earned from that record-breaking launch. Out of the 104 satellites, 96 were from the US, three from India and one each from Israel, Kazakhstan, the Netherlands, Switzerland and the UAE.

From an American perspective it is encouraging that U.S. companies dominated the satellite count. From India’s perspective, the profits here are only going to encourage that nation to push for more rockets and cheaper costs.

The one problem I see with this is that it is the government that is obtaining the profits, not private Indian citizens or companies. Such an arrangement will not be good for India in the long run, as it encourages the government to use its coercive power to squelch private competitors.

UC-Berkeley backs down will host and pay fees for conservative speaker

11:54 pm

This might be a victory: UC-Berkeley has agreed to host the lecture of conservative author Ben Shapiro in September, even if it has to pay the cost of the security required to protect the speaker and his audience from a mob of violent leftwing thugs.

The University of California, Berkeley has confirmed to FIRE it will host an on-campus event sponsored by the Berkeley College Republicans featuring conservative commentator Ben Shapiro on September 14 at 7 p.m. — even if the university has to foot the bill. “It’s clear that we have a number of workable options,” said Dan Mogulof, Berkeley’s assistant vice chancellor for public affairs. “This event is going to happen. We just need to sit down with the College Republicans to talk through the details.”

He said it was unclear whether the Berkeley College Republicans had been informed of the news.

The story provides some information that suggests the university did not initially say no to the event, as initially reported. Instead, officials had said that they didn’t have a space of the size requested and available on the requested date. This might be true, but I don’t think it unreasonable for people to not believe them considering the recent history at this university.

And yes, the real problem here is the fact that there is a mob of leftwing thugs at the university and within the Berkeley community ready and willing to violently attack anyone who dares to disagree with them, and the authorities are basically unwilling to arrest them for this behavior.

NASA and Boeing to replace damaged antenna on NASA satellite

8:49 pm

Due to an accident during satellite launch preparations, NASA and Boeing are planning to replace a damaged antenna on NASA’s TDRS-M satellite, used by NASA mainly for communications between the ground and ISS.

The update at the link however says nothing whether the satellite will still launch on August 3, as presently scheduled. Nor have they released any information about the accident itself.

Opportunity takes panorama at top of Perseverance Valley

3:38 pm

On top of Perseverance Valley

During Opportunity’s two week pause in its travels in June as engineers tried to diagnose a problem with its left-front wheel, it took a wide panorama of the surrounding terrain, including the top of Perseverance Valley, released today.

The full panorama, shown above in reduced resolution, is a bit confusing. The head of Perseverance Valley to the northeast is on the right. The view straight ahead looks west, away from the crater. The hill and raising terrain on the left is the crater rim to the south of Perseverance Valley. The panorama is not a complete 360 degree view, as it does not include a direct view to the east and into Endeavour Crater itself.

Be sure and click on the link and look at the full image. The top of the valley is really interesting to view. Was it formed by wind or water or water ice? They hope to find out.

Mueller widens witch hunt investigation

11:25 am

Special counsel Robert Mueller today widened his investigation on President Trump’s contacts with Russia during the campaign to now include Trump’s entire business transactions.

I haven’t posted anything about the Russian collusion story until now, because on its face it is absurd. As noted repeatedly by even Trump’s critics, there is no evidence of any illegal acts by anyone. Moreover, the media focus on the Russians distracts from the heart of the DNC hack, that it revealed illegal pay-offs and corruption by Hillary Clinton, John Podesta, and others in the Democratic Party. I don’t really care that much how these emails were obtained since what they uncovered is far worse.

What prompts me to post now is to underline the corruption of Robert Mueller himself. It is already well known that the investigation team he has put together includes at least seven Democratic donors, including an attorney who donated $34,000 to Democratic candidates. What I want to highlight is his blatant partisan actions to help cover up the IRS scandal for the Obama administration. I only remembered this recently, but when Mueller was called to testify to the House about his newly begun FBI investigation into that scandal, he couldn’t name the head of that investigation, even though he was the man who would have appointed such a person only a month prior.

I once again have embedded below the fold Mueller’s testimony in 2013 before Congress. Not only does he not know who is running his so-called IRS scandal investigation, he admits that not one victim of the IRS scandal had yet been contacted. In fact, none of these people were ever contacted, and that investigation never took place. Mueller stone-walled it for Obama, so that administration and president could get away with their use of the IRS as a weapon against their opponents. And of course, the Democratic mainstream media assisted them in this stone-wall by never pursuing the story. They let it fall, as they do today with the content of those hacked Clinton emails, into the memory hole.

And even if there were improprieties by Trump and his campaign, does anyone with even the slightest objectivity believe that Mueller’s investigation is going to non-partisan? I don’t. This is a witch-hunt, and it always has been.

And if you disagree with me I dare you to watch the video below. Mueller comes off clearly as a tool of the Democrats, something he still is today.

Hubble shoots movie of Phobos

10:34 am

Phobos over Mars

Cool image time! By taking a quick series of thirteen images, the Hubble Space Telescope was able to shoot a short movie of the rotation of Phobos above the surface of Mars. The gif animation on the right is the smaller of the two animations released today. Be sure and view the full resolution version.

What is even cooler is that movie was apparently unplanned. From the link:

Over the course of 22 minutes, Hubble took 13 separate exposures, allowing astronomers to create a time-lapse video showing the diminutive moon’s orbital path. The Hubble observations were intended to photograph Mars, and the moon’s cameo appearance was a bonus.

In terms of science this movie has a somewhat limited value. In terms of space engineering it is triumph, and once again illustrates the unprecedented value of having an optical telescope in space. Woe to us all when Hubble finally dies, as we have no plans to replace it.

“If you want to care for your grandson you will have to give up some of your constitutional rights.”

10:21 am

Fascist Michigan: The state’s Department of Health and Human Services has decided that for a Marine to take custody of his own grandson he needs to sacrifice his second amendment rights.

The Johnsons were going to take custody of their grandson to keep him from going into foster care. When they went to pick up their grandson, William, a retired, disabled Marine with a Concealed Pistol License (CPL), was searched for a firearm. He was not carrying a firearm at the time. At that point, agency officials told the Johnsons that they would be required to provide all firearms’ serial numbers to the agency as part of a registry. When Johnson questioned agency workers, he was given a surprising response.

“If you want to care for your grandson you will have to give up some of your constitutional rights,” a MDHHS worker retorted.

When the Johnsons appeared before a Gogebic County Court judge, the judge reiterated the agency worker’s statement. “We know we are violating numerous constitutional rights here, but if you do not comply, we will remove the boy from your home,” the judge said. [emphasis mine]

For a state judge to issue an order that he knows violates the Constitution is outrageous. He should be removed from office immediately. Unfortunately, nether the article nor the actual court papers appear to give his name.
