Rocket Lab reveals it also launched its own satellite on August 30th

9:16 am

Capitalism in space: Rocket Lab today revealed that along with placing a customer’s commercial radar satellite into orbit on August 30th, it also launched the prototype of its own satellite during the Electron rocket launch.

The company calls its satellites Photons, but rather than number them it will give each their own name. This particular satellite has been dubbed “First Light.”

The satellite is primarily a technology demonstrator, a way to test Photon’s systems in orbit and show customers what the spacecraft is capable of. First Light will stay up for the next five or six years, if all goes according to plan, Rocket Lab founder and CEO Peter Beck said during a teleconference with reporters today (Sept. 3).

Photon should be attractive to a variety of customers, allowing them to focus on their sensors and other instruments without having to worry about building and operating an entire spacecraft, Rocket Lab representatives have said.

The goal is to offer this smallsat as a platform to those who wish to launch an instrument into space but don’t want to spend the money building the satellite itself. The company also intends to use a Photon satellite for a science mission to Venus in 2023.

China launches its version of X-37B

9:05 am

The new colonial movement: It appears that China has launched its version of a reusable X-37B mini-shuttle, or at least, that is most likely first guess, based on the meager data available.

China launched a new experimental reusable space vehicle on Thursday from the Jiuquan Satellite Launch Center using a Long March-2F/T – Chang Zheng-2F/T – launch vehicle. Launch from the LC43/91 launch complex, under a veil of secrecy with no official launch photos or even a launch time disclosed.

Chinese media emitted a laconic report referring, that “the test spacecraft will be in orbit for a period of time before returning to the domestic scheduled landing site. During this period, it will carry out reusable technology verification as planned to provide technical support for the peaceful use of space.”

More at the link, though the lack of information, especially the refusal to even give a launch time, strongly indicates China wants to limit knowledge of this spacecraft’s position in space, thus limiting the ability of others to photograph it. What is known however does point to this being a variation of a small reusable unmanned shuttle, like the X-37B.

While once again China has not come up with something new, copying (or stealing) the idea from someone else, having such a vehicle gives them a significant capability. They can now test many different technologies in orbit for long periods, and get them back to Earth for study afterward.

The leaders in the 2020 launch race:

21 China
15 SpaceX
9 Russia
4 ULA
4 Europe (Arianespace)

The U.S. continues to lead China 24 to 21 in the national rankings.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

A star with giant misaligned rings

8:52 am

Star with misaligned rings

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected a nearby star, dubbed GW Ori, with multiple rings of dust with several tilted in relation to the others.

The rings, with dust equaling 75, 170, and 245 Earth masses each, are 46, 188, and 336 astronomical units (au) each from their star. (An au is the distance of the Earth to the Sun.) If you look closely at the image to the right, you can see that the inner rings are circular, while the outer rings appear oval, suggesting that we are looking directly down at the inner rings, but the outer rings are tilted to our line of sight. Moreover, another team of astronomers

…observed GW Ori with ALMA and the European Southern Observatory’s Very Large Telescope (VLT). Near infrared observation with VLT showed for the first time that the innermost ring casts a shadow on the outer rings, which is clear evidence of disk misalignment. Kraus and his colleagues also performed a computer simulation and suggest that the triple star system can create misaligned rings, without gravitational assistance from planets. The two teams have different theories for the origin of the misaligned rings, but no conclusions have been reached so far. Nevertheless, GW Ori is a precious example to understand planet formation in the complex gravitational environment around multiple stars. [emphasis mine]

As noted, there is no agreement on the cause of the misalignment, only that it does exist.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Bright-tipped perplexing terrain on Mars

Perplexing terrain on Mars
Click for full image.

The photo to the right, rotated, cropped, and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on June 24, 2020, and shows a bit of inexplicable country in Arabia Terra, the widest and largest transition zone region on Mars between the northern lowland plains and southern cratered highlands.

The stuff visible in this image falls into what I call “What the heck?” geology. It is very clear we are looking at a collection of straight and curved ridges and mesas, all of which for some reason are bright at their tips and edges. Some of the curved ridges might be the rims of craters, but only some. Other ridge lines look more like leftovers following a strange erosion process. The problem is that to my uneducated eye I can find little rhyme or reason to these shapes. The mesas and canyon on the image’s right edge might be explained by the erosion processes that create chaos terrain on Mars, but that process does not do a good job of explaining anything else in the photo.

That this uncaptioned image is merely labeled “Arabia Terra” suggests that the scientists involved in getting this image were equally perplexed by it, and could not give it a better description.

The overview map below provides some location context, including how this geology relates to the landing site of Europe’s Rosalind Franklin rover, now scheduled for a 2022 launch.

Another successful Starship prototype hop

11:15 am

Starship prototype #6 in flight

Capitalism in space: SpaceX today successfully completed a 150-meter high hop of its sixth Starship prototype, the second such hop but the first for this prototype. They have now flown two different prototypes, plus Starhopper, all successfully. No flight failures, so far.

Next they will be doing a pressure tank test, to failure, of the seventh prototype. That prototype is using what they think will be a better steel alloy, and they want to find out its limits. I have also heard that they will either fly this prototype again or fly the fifth again, sometime in the next two weeks.

I have embedded a few more images below the fold.

FAA issues Wallops Island launch license to Rocket Lab

9:21 am

Capitalism in space: The FAA has now issued a five year launch license to the smallsat rocket company Rocket Lab, allowing them to launch their Electron rocket from the company’s launch site on Wallops Island, Virginia.

The Launch Operator License allows for multiple launches of the Electron launch vehicle from Rocket Lab Launch Complex 2, eliminating the need to obtain individual, launch-specific licenses for every mission and helping to streamline the path to orbit and enable responsive space access from U.S. soil.

The company hopes to do its first launch from the U.S. before the year is out. It will then have two spaceports, allowing it to double its launch rate.

Northrop Grumman successfully tests SLS solid rocket booster

9:03 am

Northrop Grumman yesterday successfully test fired a solid rocket booster to confirm its design for use on NASA’s long-delayed and overbudget SLS rocket.

The test, completed at the T97 test area at Northrop Grumman‘s facility in Promontory, Utah, took place on Wednesday, September 2, 2020, at 1:05 PM Mountain Daylight Time (19:05 UTC). A single five-segment SLS solid rocket motor with a thrust of up to 3.6 million pounds was ignited, and burned for approximately two minutes.

The booster is an expanded version of the solid rocket boosters used on the space shuttle, with five segments instead of four, and in fact will use previously flown segments from past shuttle launches. Since this booster will not be recovered, these launches will be the last time those segments fly.

COVID-19 numbers surge after mask mandate in Hawaii

5:45 pm

More evidence masks are a very bad idea: Soon after Hawaii imposed new rules requiring masks both indoor and outdoor, the number of Wuhan virus cases and hospitalizations zoomed upwards.

Just like in the Philippines and Peru, Hawaii’s government has imposed a long, strict lockdown and has never emerged from it beyond a modified phase one reopening. Additionally, the state has had an indoor mask mandate in place since April 20 and an outdoor mandate (even while jogging!) since July 7. It is the model for what the political elites believe to be the key to stopping the spread. Yet the results are the same as they have been in every place that tried to put up a cloth in front of the inexorable spread of viral particles that can only be seen with an electron microscope.

As [indicated by the graph], Hawaii’s daily case count grew more than tenfold in July and August. All along, state officials thought they were steering this ship cleanly throughout the spring and that their draconian efforts avoided the spread of the virus. Instead, it has become clear that the virus simply arrives at southern latitudes several months later and spreads for six to eight weeks, as it does everywhere else. [emphasis mine]

I must emphasize what the author notes, that Hawaii is the most isolated U.S. state with one of the most stringent lock down and quarantine rules for visitors. Basically entering Hawaii has become difficult if not impossible, and if you do go you are required to quarantine for weeks.

Yet, as soon as they required masks, the disease’s spread accelerated.

Masks are fake science. Not only is there no solid science proving they are a benefit, the data clearly shows that if used improperly (which the general public is doing routinely) they are unsanitary and will easily promote infection and the spread of pathogens.

This data from Hawaii also proves the utter pointlessness of the lock downs. Even on this remote island the disease has arrived, and is spreading. This is what these respiratory viruses do. The best way to fight them is let them spread as fast as possible among the young and healthy population, which will easily fight them off and become immune and thus act to choke off any further spread to more vulnerable populations.

Biggest black hole merger yet detected by gravitational waves

3:30 pm

The uncertainty of science: In May 2020 scientists using the LIGO and VIGO gravitational waves telescopes detected evidence of a merger from two giant black holes, one of which was of a size that according to all theories had been considered “impossible.”

The short gravitational wave signal, GW190521, captured by the LIGO and Virgo gravitational wave observatories in the United States and Europe on 21 May last year, came from two highly spinning, mammoth black holes weighing in at a massive 85 times and 66 times the mass of the Sun, respectively.

But that is not the only reason this system is very special. The larger of the two black holes is considered `impossible’. Astronomers predict that stars between 65 – 130 times the mass of the Sun undergo a process called pair instability, resulting in the star being blown apart, leaving nothing behind.

With a mass of 85 solar masses, the larger black hole falls squarely in that forbidden range, referred to as the upper black hole mass gap, and should be `impossible’.

The explanation the scientists propose is that this black hole initially formed with a mass smaller than 65 solar masses, and then sucked in matter, including a possible additional black hole merger, that raised its weight to 85 solar masses.

A nation of control freaks

12:19 pm

Americans have not simply in the past six months become trapped in terror and fear over a relatively low-level virus, they have compounded that fear with a strong and ever-growing desire to tell everyone else what to do.

The conservative internet has been pushing the term “Karen” to apply to any busybody who wishes out of outrage to wield petty power over everyone around them. I find that term too vague. A much more apropos term would be to call them what they are: control freaks.

And sadly, there now are a lot of them, many of which are downright insane in their demands and willingness to commit violence to impose their will.

Want to hold a small wedding in Hawaii near the beach, with maybe no more than ten people attending? Nope, you can’t, because someone will arrive to harass you rudely and demand you be arrested. The Democratic state government there has declared the beaches closed, public weddings illegal, and private enterprise under strict control, all over a virus that appears only mildly more dangerous than the flu.

Want to sing in church and you live in California? Nope, you can’t, because Gavin Newsom, the Democratic governor of that state has declared such singing and chanting dangerous. It will spread the Wuhan flu! (He doesn’t have a problem with leftist Antifa and Black Lives Matter protesters chanting “Death to America” slogans however. Leftist protesters are immune from the virus.)

It isn’t just the rules imposed over COVID-19 however. » Read more

The longest lava tube in the solar system?

9:19 am

A lava tube on Mars
Click for full image.

Before I delve into today’s cool image, I think it important to explain to my readers why I seem to post so many cool images from Mars. The simple explanation is that Mars right now is where almost all the cutting edge planetary research is taking place, and as a science journalist focused on space exploration I must go to that cutting edge. My dear readers know that I love variety (just consider the evening pauses on Behind the Black), but you can’t ignore the reporting of real discoveries simply to increase the diversity of one’s posts. This is too often what modern news outlets do, which is also why they often miss the real story.

Anyway, today’s cool image to the right, rotated, cropped, and reduced to post here, shows only a small section of what might be the longest lava tube in the entire solar system. Taken on May 5, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), it shows a string of pits along a meandering depression coming down the northwest flank of the giant volcano Arsia Mons. The image was a follow-up to a July 2014 photo of the same location, and was taken to produce a stereo pair.

The feature strongly suggests a lava tube, with the pits being skylights into the meandering underground void. From top to bottom this section of the tube is a little over three miles long. Since there are lava tubes on Earth far longer, this one image hardly makes this the longest tube in the solar system.

The tube, however, extends off the image both at the bottom and at the top. Not many high resolution images have been taken in this area, so it is therefore hard to say how far the tube extends. Other nearby high resolution images in this area however have found similar lava tubes, which conceivably could be part of the same tube. The overview map below shows the relationship.

Musk gives update on Starship/Super Heavy

8:11 am

Capitalism in space: During a phone conversation at a conference earlier this week, SpaceX founder Elon Musk gave an update on the development of Starship/Super Heavy, intended to be the first completely reusable rocket.

He did not reveal much that isn’t already known but his broad overview is helpful for understand what is happening at the company’s development facility in Boca Chica, Texas. One detail of note:

Asked on Monday when SpaceX might perform the first orbital Starship launch and re-entry, Musk replied: “Probably next year.”

“I hope we do a lot of flights,” Musk continued. “The first ones might not work. This is uncharted territory. Nobody has ever made a fully reusable orbital rocket. So just having that at all is pretty significant.”

Musk also said that they plan to do a lot of orbital flights before upgrading the ship for humans. I think his experience with Dragon has influenced him on this score.

COVID-19 illnesses after half million people attend Sturgis rally: almost none

10:24 pm

Can we please put aside our fear? Almost two weeks after about a half a million people attended the Sturgis motorcyle rally in South Dakota (an event that spanned ten days), only three hospitalizations from COVID-19 have been linked to this event, and two of those have already recovered.

I can only find confirmation of three hospitalizations at this point in the reporting. Two of the patients have confirmed discharges indicating they will fully recover. Since they had symptoms and developed them within fourteen days of the rally, contracting the virus during their travels or attendance seems likely. By way of contrast, there were four fatal crashes at the Sturgis event that killed five people.

Even using the largest number of positive tests and granting they all 222 resulted from rally attendance, 0.048% of attendees and contacts tested positive for COVID-19. Some states have done contact-tracing on people who tested positive post-rally and included those individuals in their reporting.

You won’t see this reported in the media nationally. It is too much good news. If almost half a million people can gather for an event that spans 10 days with this outcome, it puts their COVID-19 panic porn to rest.

If you saw any videos from this rally, you saw that most people were not social distancing, were not wearing masks, and were having a darn good time.

COVID-19 is not dangerous. You won’t get it easily, or if you do, you are likely not to even know. And if you do get sick, you will almost certainly recover, like the flu. The only people who should be concerned about the virus are those with other serious illnesses who likely should not attend such large events anyway.

A collapsed Martian crater in a glacier?

12:43 pm

Collapsed crater in glacier?
Click for full image.

Today’s cool image to the right, cropped and reduced to post here, is another example of evidence that the mid-latitudes of Mars are covered with glaciers and ice. The photo, taken on April 25, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), shows many of the squashed and blobby features found in these mid-latitudes.

What makes the image even more interesting is the small crater in the center of the larger crater. The floor of that larger crater seems filled with glacial fill, and it appears that when that smaller impact occurred it caused the nearby surrounding fill to collapse downward, producing the oblong off-center depression. At least that’s my uneducated guess, which I admit could easily be wrong.

Even if my hypothesis is wrong, the visual evidence here supports the theory that this region, dubbed Deuteronilus Mensae, has lots of buried ice glaciers. Consider for example the distorted crater to the southwest of the big crater. It sure looks like at some point it was heated suddenly, maybe by the impact of the main crater, so that its rim was warped and reshaped, in the manner that ice would be warped and reshaped by sudden heat. Moreover, all the craters in full image appear to have glacial fill.

The overview map below adds weight to this conclusion.

COVID-19 is simply not life-threatening

9:50 am


The fading and not very threatening COVID-19 epidemic
in California. Note how masks appear to increase the
disease’s spread. Note also how this doesn’t seem to
change the death toll significantly. Go here for more details.

In the past few days there have been a flurry of new reports proving once again that the panic over the Wuhan virus was completely unnecessary, that the disease was exactly what the initial data suggested, a variation on the flu that would be, like the flu, harmless to the healthy and young while dangerous to the elderly sick.

And like the flu, the Wuhan virus required no extreme measures. All we had to do was protect those elderly sick, and let everyone else continue living their lives normally.

First we have the revelation this weekend, from the CDC no less, that the number of people who died only from COVID-19, with no other health issues, was only about 6% of the total deaths assigned to the disease, or only about 9,700 people total, an infinitesimal percentage of the total population.

The Centers for Disease Control and Prevention (CDC) website disclosed the shockingly small number of people who died from only the Wuhan coronavirus, with no other cause of death mentioned. Hold on to your hat because here it is: out of the 161,392 deaths in the CDC data, just six percent, about 9,700 deaths, were attributed to the coronavirus alone. According to the CDC, the other 94 percent had an average of 2.6 additional conditions or causes of deaths, such as heart disease, diabetes, and sepsis. [emphasis mine]

Let that sink in. The Wuhan virus killed you only if you had an average of slightly less than three serious chronic health conditions. And generally you had to be elderly, with the average age of death 78 years old. Otherwise, just like the flu you might have been sick for a few days, but you would have recovered and been able to go on with your life as normal. This data once again demonstrates that the masks, the shut downs, and the economic disaster were all unnecessary.

Then on Friday we had another research paper, one of a long continuing string of papers, finding once again that COVID-19 is of no threat to young children at all, that they not only don’t get sick from it they also don’t infect anyone else.

Revisiting Mars’ glacier country

1:16 pm

Glacial cracks or pits on Mars
Click for full image.

With today’s cool image we return to what I have labeled glacier country on Mars, though this time the image shows a Martian glacial feature that while resembling vaguely such features seen on Earth, has an alienness to it that requires some explanation.

The photo to the right, cropped to post here, was taken on March 24, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The section I have focused on is the floor of a depression with a number of parallel pits, more or less aligned with the packed north-south ridges that cover the entire floor.

Normally, the north-south ridges would suggest repeated glacial flows moving to either the west or to the east. Such movement could over time, cause the ridges to separate, creating the cracks or pits that we see here. The trouble is that the slope of this depression is very unclear. In fact, the wider view below shows that this depression appears mostly enclosed, or if not it does not seem to be flowing in any particular direction.

What really happened this past weekend in American rocketry

9:44 am

SpaceX's first Starship prototype
SpaceX’s first Starship mock-up,
January 2019

Three days ago it appeared that the past weekend would see four private Americans companies attempt to launch six different times with five different rockets from four different spaceports, all in less than two days.

Not surprisingly, things didn’t happen as planned. Of the six launches, three were rescheduled because of poor weather. First, bad weather in Kodiak, Alaska forced the new startup Astra to cancel its first attempt to complete an orbital flight with its Rocket 3.0, rescheduling to no earlier than September 10th.

Then, in Boca Chica, Texas, SpaceX twice tried on August 30th to launch its sixth Starship prototype on a 500 meter hop, both times scrubbing because of high winds. They are going to wait a few days before trying again.

Finally, in Florida SpaceX scrubbed its first Falcon 9 launch on August 30th for the same reason, rescheduling it for tomorrow, September 1st.

A fourth cancelled launch, by ULA using its Delta 4 Heavy rocket, occurred when the rocket did an automatic launch abort three seconds before liftoff. The company has not yet rescheduled as they try to figure out what caused the problem.

Two launches however did get off this weekend. both on August 30th. First the weather at Cape Canaveral cleared enough by evening for SpaceX to successfully launch a Falcon 9 rocket, putting an Argentinian satellite into orbit. Next that same evening Rocket Lab returned to flight after a July failure with the launch of its Electron rocket from New Zealand.

So, only two of six launches lifted off. While some of today’s fear-mongers and fans of misfortune would call this a sign of failure, it is nothing of the sort. If anything, it illustrates the slow maturing of American rocketry, from a technology that once only rarely could launch to one that now has the potential to dominate the world with multiple companies competing aggressively in an open free market, assuming of course that our increasingly fascist society doesn’t decide to shut it down.

SpaceX successfully launches Argentina satellite

4:37 pm

Capitalism in space: SpaceX tonight successfully launched an Argentinian radar satellite into polar orbit, the first such launch from Cape Canaveral since the 1960s.

The company also successfully landed the first stage at the Cape, completing that stage’s fourth flight. As I write this they still have two more smallsats to deploy, but it is very unlikely they will have an issue doing so.

The leaders in the 2020 launch race:

20 China
14 SpaceX
9 Russia
4 ULA

The U.S. now leads China 22 to 20 in the national rankings. With a scheduled launch by Rocket Lab from New Zealand later tonight, these numbers could change again before the day is out.

SpaceX scrubs Starship prototype hop

3:32 pm

Capitalism in space: Though it appeared twice today that SpaceX engineers were on the verge of executing their second Starship prototype hop, the first for prototype #6, in both cases they stood down.

It appears according to road closures in Boca Chica they will try again tomorrow. The live stream is available here. The closures go from 8 am to 8 pm (Central), within which the hop could occur at almost any time, but likely not before 9 am.

Problem with InSight’s weather station

3:18 pm

Engineers are troubleshooting a problem with the weather sensors on the InSight lander on Mars that has prevented them from collecting data since August 16th.

[The weather system] is in safe mode and unlikely to be reset before the end of the month while mission team members work toward a diagnosis. JPL engineers are optimistic that resetting the control computer may address the issue but need to investigate the situation further before returning the sensors to normal.

Overall InSight has turned out to be of mixed success. The seismometer has worked as planned, but the mole designed to drill the heat thermometer sixteen feet into the ground has so far failed to work, and now the weather station has shut down, though hopefully only temporarily.
