SpaceX launches sixty more Starlink satellites; plus an installation report from one customer

February 15, 2021 10:06 pm Robert Zimmerman

Capitalism in space: SpaceX tonight successfully launched another 60 Starlink satellites, using its Falcon 9 rocket.

The first stage on its sixth flight however failed to land successfully. It is amazing that we now expect these landings to succeed, proving how reliable we now expect SpaceX’s rocket to be.

The 2021 launch race:

5 SpaceX
3 China
2 Russia
1 Rocket Lab
1 Virgin Orbit

The U.S. now leads China 7 to 3 in the national rankings. Another SpaceX launch is scheduled for tomorrow, followed by a Rocket Lab launch a little more than 24 hours later.

A report from one Starlink customer on his installation experience

The sixty new Starlink satellites bring the constellation to more than 1,100 satellites, allowing SpaceX to continue expanding regions where it is offering the service. Below the fold is an update from reader Steve Golson on his experience installing his own Starlink dish and service in Maine, now running for several days. Rather than cut and past sections, I think it best to quote his email to me in its entirety, including some of the images he sent. The opinions expressed are Steve’s alone, but they are coming from a customer who appears very satisfied with the product, up to now.

New paper: Underlying ice layer seen in Martian gullies at LOW mid-latitudes

February 15, 2021 2:18 pm Robert Zimmerman

Click to see full image.

In a paper just published, scientists are proposing that bright areas seen in the low mid-latitude gullies on Mars are the underground ice table newly exposed as surface dust is removed.

This paper is a reiteration in more detail of a previous presentation [pdf] by these same scientists at the 2019 the 50th Lunar and Planetary Science Conference in Texas and reported here in March 2019.

The image to the right, from the paper, was taken by the high resolution camera of Mars Reconnaissance Orbiter (MRO) in 2009, and has been cropped to post here. The white streaks are what the scientists propose is that exposed underground ice table. At 32.9 south latitude, this particular gully would be the closest to the equator that such an ice layer has been identified. All the previous ice layer discoveries have been in the ice scarps found at latitudes above 50 degrees. As the paper’s lead author, Aditya Khuller at Arizona State University, explained in to me in an email, “We believe we are seeing exposures of dusty ice that likely originated as dusty snow.” From their paper:

We suggest … that the light-toned materials are exposed H2O ice. … [T]he appearance, and then subsequent disappearance of these light-toned materials, suggests that they are some form of volatile, such as dusty ice, rather than dust alone. … [The appearance] of these light-toned materials is similar to the >100m thick, light-toned ice deposits exposed on steep mid-latitude scarps, indicating that these materials are probably also ice, with some amount of dust on, and within the ice.

The layer would have likely been laid down as snow during a time period (a long time ago) when the rotational tilt of Mars, its obliquity, was much higher than today’s 25 degrees. At that time the mid-latitudes were colder than the poles, and water was sublimating from the polar ice caps to fall as snow in the mid-latitudes.

The overview map below reveals some additional intriguing possibilities.

Today’s blacklisted Americans: All religious schools

February 15, 2021 11:10 am Robert Zimmerman

The cancelled Bill of Rights

They’re coming for you next: The homosexual lobby is pushing the Biden administration to deny accreditation to any religious school that did not endorse its political and sexual agendas.

The Human Rights Campaign (HRC), America’s largest and most powerful LGBT lobby organizations, is pushing Joe Biden and Kamala Harris to target Christian educational institutions, demanding that the Biden Administration strip colleges that adhere to rules and positions opposing homosexuality of their accreditation. The HRC’s “Blueprint for Positive Change,” which offers 85 recommendations, proposes eliminating non-discrimination exemptions for religious colleges if they refuse to abandon the biblical position on marriage.

The Blueprint states, “Language regarding accreditation of religious institutions of higher education in the Higher Education Opportunity Act could be interpreted to require accrediting bodies to accredit religious institutions that discriminate or do not meet science-based curricula standards. The Department of Education should issue a regulation clarifying that this provision, which requires accreditation agencies to ‘respect the stated mission’ of religious institutions, does not require the accreditation of religious institutions that do not meet neutral accreditation standards including nondiscrimination policies and scientific curriculum requirements.”

In other words, if a religious school forbids homosexual behavior among its students or teaches it is a sin, based entirely on that school’s religious beliefs, it accreditation should be cancelled, and its ability to provide students legally recognized degrees eliminated.

Understand that if you are homosexual you have plenty of very friendly schools to go to that will celebrate your sexual preferences and beliefs. No one is oppressing you because a Christian, Evangelical, or Orthodox Jewish school believe otherwise.

That’s not enough however for the leftist gay lobby. Just because it has successfully created positive options for itself throughout society it must still destroy any options for those who disagree with it. This is the epitome of oppression and intolerance.

At this moment the Biden administration has not accepted these recommendations, but if you think it won’t, I have a bridge in Brooklyn I want to sell you. One of the very first executive orders signed by Biden was one that required schools to let men who “identify” as women compete in women’s sports. They remain men in every biological sense except the clothes they wear, their hairstyle, and (most important) their utterly delusional belief they are a women.

If Joe Biden and the Washington leftist crowd that runs our federal government thinks this edict makes rational sense, we must expect them to do whatever they can to shut down religious schools for daring to express any dissent of the homosexual movement’s agenda.

The first amendment be damned! You are all going to obey our new leftist lords, or you will be silenced!

Russia launches Progress freighter to ISS

February 14, 2021 11:40 pm Robert Zimmerman

Russia today successfully launched a new Progress freighter to ISS using its Soyuz-2 rocket, bring almost three tons of supplies to the station..

The 2021 launch race:

4 SpaceX
3 China
2 Russia
1 Rocket Lab
1 Virgin Orbit

The U.S. still leads China 6 to 3 in the national rankings. That lead should widen this week with three American launches scheduled, two Starlink launches from SpaceX and one Cygnus freighter from Northrop Grumman.

UAE releases first Al-Amal image of Mars

February 14, 2021 9:45 am Robert Zimmerman

Click for full image.

The new colonial movement: The leader of the United Arab Emirates (UAE) yesterday released on his twitter feed the first photo of Mars that was beamed back from its Al-Amal (“hope” in English) orbiter, taken shortly after achieving orbit.

That photo is to the right, cropped and reduced to post here. From the article at the link:

[The photo] was captured by Hope’s EXI instrument from an altitude of 24,700 km (15,350 miles) above the Martian surface at 20:36 GMT on Wednesday – so, one day after arriving at the Red Planet.

The north pole of Mars is in the upper left of the image. At centre, just emerging into the early morning sunlight, is Olympus Mons, the largest volcano in the Solar System. Look right on the boundary between night and day, the so-called terminator.

The three shield volcanoes in a line are Ascraeus Mons, Pavonis Mons, and Arsia Mons. Look east, to the limb of the planet, and you can see the mighty canyon system, Valles Marineris. It’s part covered by cloud.

Right now the spacecraft’s orbit is very eccentric, ranging from 600 to 30,000 miles above the Martian surface. After several orbital trims, Al-Amal will end up in an orbit about 14,000 by about 27,000 miles, with an inclination of about 25 degrees. From that high orbit it will then focus on studying the Martian atmosphere.

Thus, future images will likely be similar to this, global and mostly aimed at tracking visible phenomenon in the atmosphere (dust storms and clouds).

1st Vulcan test core stage arrives at Kennedy

February 14, 2021 9:31 am Robert Zimmerman

Capitalism in space: ULA’s first complete Vulcan core stage, meant at this point only for testing launch procedures, has arrived at Cape Canaveral.

After connecting the launch platform and the rocket to gas and electrical systems at the pad, ULA engineers will run the Vulcan booster and the ground infrastructure through a series of exercises, culminating in loading of thousands of gallons of cryogenic liquid methane and liquid oxygen into the rocket.

Once these tests are complete, the stage will be returned to ULA’s facility in Alabama to be refitted with flight worthy BE-4 engines so it can fly on a later mission. The engines presently attached are test engines.

ULA expects the first flightworthy BE-4 engines to be delivered by Blue Origin by the summer. These will then be incorporated into the first Vulcan to fly (hopefully before the end of the year) and carrying Astrobotic’s unmanned Peregrine lunar lander.

That rocket, as will all Vulcan rockets for the foreseeable future, will be entirely expendable. Though ULA says it intends at some point to recover for reuse the engines of the core stage, they have not delineated a time schedule for when that will happen.

At this point the only customer ULA has for this rocket is the government — especially the military. Vulcan cannot compete in price with SpaceX’s rockets, so I doubt any commercial satellite company will be much interested in it. The military will pay the extra bucks, because it wants more than one launch company for redundancy, and it has already committed to buying Vulcans for the next five years.

Of course, that long term commitment to Vulcan by the military will likely change if other cheaper rockets enter the market. At the present the military is limiting bidding on future launches to just SpaceX and ULA. That cannot hold up in court if other viable rocket companies wish to bid. Expect those new companies to do what SpaceX did when the Air Force refused to let it bid on military launches about five years ago, sue, and win in court.

At that point ULA’s an entirely expendable Vulcan will be very vulnerable to losing its last customer. ULA must make this rocket reusable or it will die as a company.

Abraham Lincoln – an annual tribute

February 12, 2021 6:01 pm Robert Zimmerman

An evening pause: On this, the birthday of Abraham Lincoln, I must once again honor his memory, most especially because the Marxist, anti-American bigots who are now running roughshod across our once free nation wish to cancel him by actually accusing the man who freed the slaves of being a racist.

And though he freed the slaves, I think Lincoln’s most enduring contribution to American history, a contribution that now has sadly been lost, was his limitless good will for everyone, even to those who hated him and wished to kill him. Had he not been assassinated, American history might have been far better because Lincoln would have had the clout to ease the worst elements of Reconstruction, while forcing through reforms in the former southern slave states.

The modern Democrats in Congress — and their supporters nationwide — might benefit by reading some history about Lincoln. Alas, I have no hope of this.

As I wrote for last year’s tribute,

Lincoln stood for freedom for all humans, the central heart of the American experiment. He was willing and did die for that stance. We should all be willing to do no less.

The video below shows probably every photograph ever taken of Lincoln, in chronological order. You can see him age and mature. You can also see a gaunt and serious man who appears to care deeply about whatever he does.

Today’s blacklisted American: New conservative organization at Illinois Tech blacklisted by students

February 12, 2021 1:30 pm Robert Zimmerman

The cancelled Bill of Rights

They’re coming for you next: When a conservative student at the Illinois Institute of Technology proposed starting a chapter of the national conservative organization Turning Point USA (TPUSA) at the school, a slander campaign was immediately started by other students against both TPUSA and the student, forcing him to back down.

[After his proposal was put forth], classmates began to message his fraternity brothers, asking whether he was attempting to lead a “hate group” on campus. The conservative student said that this occurred on three separate occasions.

On January 27, the conservative student again presented to the student government — this time, to withdraw his proposal. The conservative student emphasized that he had no malicious intent in proposing a TPUSA chapter, but merely aimed to start a political discourse on campus. The conservative student apologized for proposing a TPUSA club and stated that he would consider forming a group under another national conservative organization.

Derek Rhea, the executive vice president of the Student Government Association commented that the “entire campus had been completely mobilized,” leading to a “huge movement on the opposing side” against the prospect of a TPUSA group at Illinois Tech. He applauded the conservative student for withdrawing his request to start a TPUSA chapter.

Senator Hannah-Lauren Moreno asked whether the conservative student was pressured into rescinding his request. The conservative student informed the student government that classmates began to wonder if he, his peers, and his fraternity brothers were “terrible people” for trying to start the club.

Following the January 27 student government meeting, the conservative student provided Campus Reform with screenshots, one of which appears to show a student rejoicing in an online message that “we managed to successfully cyber bully a student org to death.” [emphasis mine]

There is only one reason these partisan leftists (and that’s what they are) wanted to block a new TPUSA chapter. Unlike the moribund and largely uninteresting and dull Republican Party clubs, TPUSA has been very effective on campuses nationwide at countering leftwing hate and censorship while drawing to it large numbers of new students, teaching them that conservative values are about freedom and justice and equal treatment before the law, not the left’s slanderous lies of “white supremacy” and “hate.”

I highlighted the words of Rhea above because if he is telling the truth and a “huge movement” of students formed to blacklist this organization we are in very big trouble. This indicates that the next generation is truly all in with censorship and blacklisting, and will likely soon consider imprisoning anyone who disagrees as perfectly reasonable.

It is also possible that this guy is lying, and that the so-called “huge movement” was a handful of loudmouthed bullies, who have successfully learned how to use social media to intimidate everyone else. In this case Rhea is one of those bullies, and he is using his position as VP of the student government for that depraved purpose.

Either way, I guarantee that should this student return to propose a club linked to a different conservative organization, these same bullies will appear, making the same slanderous claims. They lie when they say they would accept other conservative organizations. They want them all banned, and play this game to make sure none ever appear.

Rover update: The rovers are coming! The rovers are coming!

February 12, 2021 12:52 pm Robert Zimmerman

With the imminent landing on Mars of both the American rover Perseverance only days away on February 18th followed by China’s rover in April, I think it time for a new rover update, not only providing my readers a review of the new landing sites but a look at the most recent travels of Curiosity on Mars and Yutu-2 on the Moon.

Overview map of Curiosity's most recent and future travels

The panorama above, made from four images taken by Curiosity’s right navigation camera on February 12, 2021 (found here, here, here, and here), looks south to the base of Mount Sharp, now only a short distance away. The yellow lines on the overview map to the right show the area this panorama covers. The white line indicates Curiosity’s previous travels. The dotted red line in both images shows Curiosity’s planned route.

The two white dots on the overview map are the locations of the two recurring slope lineae along Curiosity’s route, with the plan to get reasonable close to the first and spend some time there studying it. These lineae are one of Mars’ most intriguing phenomenon, seasonal dark streaks that appear on slopes in the spring and fade by the fall. There are several theories attempting to explain their formation, most proposing the seepage of a brine from below ground, but none has been accepted yet with any enthusiasm.
