Northrop Grumman launches U.S. reconnaissance satellites

9:25 am

Capitalism in space: Northrop Grumman today successfully used its Minotaur-4 rocket to launch four U.S. reconnaissance satellites for the National Reconnaissance Office.

Minotaur-4 is essentially re-purposed military ICBM that had been decommissioned, refurbished, and upgraded for orbital flight. This was its first launch from Wallops Island in Virginia. This was also Northrop Grumman’s second launch this year, which still leaves them out of the 2020 launch race leader board:

16 China
10 SpaceX
7 Russia
3 ULA

Today’s launch however puts the U.S. ahead of China in the national rankings, 17 to 16.

A journalist blasts the New York Times in resignation letter

10:54 am

Link here. It appears that the author of this resignation letter, Bari Weiss, had been hired by the New York Times after the 2016 election because the editors there had realized the paper had become to captured by its leftist bubble and had misread the public’s support for Trump in the election. Weiss, whose credentials suggest a more well-rounded background, was hired to give the Times a peek outside its leftist bubble.

Well it appears the Times and its employees don’t really want that peek. From the resignation letter:

The paper of record is, more and more, the record of those living in a distant galaxy, one whose concerns are profoundly removed from the lives of most people. This is a galaxy in which, to choose just a few recent examples, the Soviet space program is lauded for its “diversity”; the doxxing of teenagers in the name of justice is condoned; and the worst caste systems in human history includes the United States alongside Nazi Germany.

Even now, I am confident that most people at The Times do not hold these views. Yet they are cowed by those who do. Why? Perhaps because they believe the ultimate goal is righteous. Perhaps because they believe that they will be granted protection if they nod along as the coin of our realm—language—is degraded in service to an ever-shifting laundry list of right causes. Perhaps because there are millions of unemployed people in this country and they feel lucky to have a job in a contracting industry.

Or perhaps it is because they know that, nowadays, standing up for principle at the paper does not win plaudits. It puts a target on your back. Too wise to post on Slack, they write to me privately about the “new McCarthyism” that has taken root at the paper of record.

None of this really is a surprise. Persecution is now cool, and the leftist orthodoxy that controls academia and journalists at the Times all want to be cool.

Worse is yet to come. Be warned. They’re coming for you next.

Launch delays for SpaceX and UAE

12:21 am

The launches planned for tomorrow by SpaceX and Japan’s space agency JAXA have both been postponed, for different reasons.

The SpaceX launch of a South Korean military satellite was postponed in order to swap out equipment in the Falcon’s upper stage. No new launch date has yet been announced.

The JAXA launch, using Mitsubishi’s H-2A rocket, was to launch the United Arab Emirates’ Mars orbiter Hope. It was postponed due to bad weather. Their next launch window is July 16, but they have not yet announced a new launch date. Like Perseverance, they must launch this summer or they will have to wait two years for the next launch window to Mars to reopen.

SpaceX about to set reuse record for fastest turnaround ever

9:09 am

Capitalism in space: If tomorrow’s launch of a South Korean military satellite by SpaceX’s Falcon 9 rocket succeeds, it will set a new all-time record for the fastest turnaround of a used rocket, 44 days.

The previous record was 54 days, set by the space shuttle Atlantis in 1984. The article notes however the spectacular differences:

By far the most impressive aspect of Falcon 9’s imminent record is the comparison between the resources behind Space Shuttle Atlantis’ 54-day turnaround and Falcon 9 booster B1058’s ~44-day turnaround. Around the time NASA and Atlantis set the Shuttle’s longstanding record, some 5000-10000 full-time employees were tasked with refurbishing Space Shuttles and the facilities (and launch pads) that supported them. Based on retrospective analyses done after the STS program’s end in 2011, the average Space Shuttle launch (accounting for the vast infrastructure behind the scenes) ultimately wound up costing more than $1.5 billion per launch – more than the Saturn V rocket the Shuttle theoretically replaced.

According to a uniquely detailed May 2020 AviationWeek interview with SpaceX CEO Elon Musk, Falcon 9 booster turnaround may cost as little as $1 million apiece and can be managed from start to finish by several dozen employees at most. In other words, even though SpaceX boosters are suborbital and stressed quite a bit less than orbital Space Shuttles, Falcon 9 reuse is approximately a thousandfold more efficient that Space Shuttle reuse. [emphasis in original]

I should add that SpaceX also has three more launches on tap for the rest of July. If all lift off, the company will have launched four rockets in only three weeks, which in itself will be a record. No private rocket company has ever launched so frequently and so routinely. And only Russia during its Soviet Union heydays has come close to launching with this frequency.

Midnight repost: The think tank culture of Washington

11:59 pm

The tenth anniversary retrospective of Behind the Black continues: The essay below, first posted on June 22, 2016, was the result of a Washington DC. trip, occurring during the heat of the presidential campaign just after Donald Trump had become the Republican candidate for president.

The impression I got of the Washington culture then has sadly proven more accurate than I would have ever guessed. And their response to Trump’s election was just as I feared.

———————————-
The Think Tank Culture of Washington

On Monday I attended and gave a presentation at the one-day annual conference of the Center for New American Security (CNAS) in Washington, D.C., in conjunction with the space policy paper I am writing for them, Exploring Space in the 21st Century.

CNAS was founded ten years ago by two political Washington insiders, one a Democrat and the other a Republican, with a focus on foreign policy and defense issues and the central goal of encouraging bi-partisan discussion. For this reason their policy papers cover a wide range of foreign policy subjects, written by authors from both political parties. The conference itself probably had about 1,000 attendees from across the political spectrum, most of whom seemed to me to be part of the Washington establishment of policy makers, either working for elected officials, for various executive agencies, or for one of the capital’s many think tanks, including CNAS.

I myself was definitely not a major presenter at this conference, with speakers like Vice President Joe Biden, Senator Lindsey Graham (R-South Carolina), and Senator Joe Reed (D-Rhode Island). I was part of a panel during one of the lunch breakout sessions, where approximately one third of the attendees came to have lunch while we spoke about space. I only had ten minutes to speak, and used that time to outline (1) the influence SpaceX is having on the entire launch industry and (2) the vast differences in cost, development time, and results between the Orion/SLS program and commercial space. Not surprisingly, the aerospace people from the big established companies appeared to be somewhat uncomfortable with what I had to say, though the Airbus people liked it when I made it clear I thought that the U.S. should allow foreign companies to compete for American business, including government launches.

Their discomfort was best illustrated by the one question asked of me following my talk, where the questioner said that I was comparing apples to oranges in comparing a manned capsule like Orion, intended to go beyond Earth orbit, with the unmanned cargo capsules like Dragon and Cygnus, that only go to ISS. I countered that though I recognized these differences, I also recognized that the differences were really not as much as the industry likes to imply, as demonstrated for example by SpaceX’s announcement that they plan to send Dragon capsules to Mars beginning in 2018. After all, a capsule is still only a capsule. The differences simply did not explain the gigantic differences in cost and development time.

I added that Orion compares badly with Apollo as well, noting that Apollo took about a third as long to build and actually cost less. I doubt I satisfied this individual’s objections, but in the end I think future policy will be decided based on results, not the desires of any one industry bigwig. And in this area Orion/SLS has some serious problems. I hope when my policy paper is released in August it will have some influence in determining that future policy.

My overall impression of CNAS, the speakers, and the people who attended was somewhat mixed. Having lived in the Washington, D.C. area from 1998 to 2011, when I attended many such conferences, I found that things haven’t changed much in the last five years. Superficially, everyone was dressed in formal business suits (something you see less and less elsewhere), and they also got to eat some fancy food at lunch.

On a deeper level my impressions were also mixed.

Midnight repost: Al Gore and the silencing of debate

11:59 pm

The Behind the Black tenth anniversary retrospective: Today’s repost is from August 29, 2011, and was one of my earliest essays describing the real meaning of the scientific method.

——————————–
Al Gore and the silencing of debate

Yesterday I posted a link to a story about Al Gore claiming that any expression of skepticism about global warming is to him no different than racism. Here again is what Gore said,

“There came a time when friends or people you work with or people you were in clubs with — you’re much younger than me so you didn’t have to go through this personally — but there came a time when racist comments would come up in the course of the conversation and in years past they were just natural. Then there came a time when people would say, ‘Hey, man why do you talk that way, I mean that is wrong. I don’t go for that so don’t talk that way around me. I just don’t believe that.’ That happened in millions of conversations and slowly the conversation was won. We have to win the conversation on climate.”

More than at any other time, Gore here has very successfully illustrated the differences between how climate skeptics debate the scientific questions of climate change versus how global warming advocates do it.

Falcon 9 landing leg falls during retraction

10:15 am

Capitalism in space: During the processing to bring a used Falcon 9 first stage back to its hanger after its June 30th launch, one of the landing legs unexpectedly fell back to the ground during retraction.

I have embedded the video of the incident, cued to the event, below the fold. No one was hurt, and it appeared that nothing was damaged. It appears it happened because a cable holding the leg vertical snapped just before the leg got latched in place on the side of the rocket.

Midnight repost: No obscenities on Behind the Black

11:59 pm

The tenth anniversary retrospective of Behind the Black continues: I first posted these rules pertaining to commenting on Behind the Black on December 31, 2017, but have always adhered to them.

Anyone, without registering, can come this website and comment about anything (though preferably in connection to something I have posted), as long as they act like an adult. If they want to point out an error in something I’ve written, great. If they want to disagree with me civilly, even better. All they have to do is keep their language clean and not resort to childish insults.

Over the years since I have been amazed how many people in today’s increasingly barbaric culture can’t seem to do this simple thing. Thus I think these rules bear repeating, if only to outline to my many new readers where I stand on this issue. (Note that since I posted this I have relaxed the rules slightly. First time offenders are now issued a warning instead of being suspended immediately.)
———————
No obscenities on Behind the Black

I have stated this now bluntly more than a few times. I will not tolerate obscenities or curse words on this website. Despite this, today two different regular commenters thought it was perfectly fine to ignore these rules. One I have suspended for a week. The other might be.

The rest of the world might want to wallow in barbarism and ill behavior, but it will not happen here. This is my workplace. If you want to participate in the conversation on Behind the Black, I expect you to act like a civilized adult. If you can’t abide by these rules, then go somewhere else.

And don’t think it is okay to quote someone else verbatim and get away with this. As I noted just now in a reply to the suspended commenter, when Richard Nixon’s White House used the term [expletive deleted] everyone knew what it meant. It wasn’t a great solution, but it at least showed that they recognized that it was inappropriate to nonchalantly print obscenities, even ones spoken by the president. At the same time, they knew they couldn’t edit the transcripts, so they found a way to make it clear what was on the tapes without adding to the misbehavior.

Consider this a final warning. From now on I will not simply delete the obscenity and issue a warning. From now on, any violation of this rule will get an immediate suspension for a week. A second violation by the same person will get them banned.

Air Force looking to buy flying cars

9:35 am

The Air Force is looking to buy commercially-made flying cars designed using drone technology.

The advantages of vertical landing and take-off are many. For example, they would not need runways that are targets and must be defended. They can take off and land practically anywhere. In the past however the cost and practicality of making an airplane do this has been a major obstacle.

Normally I would see an article like this in the military press as simply a lobbying effort by a government agency to garner a bigger budget for itself. That still might be the case, but this part of the Air Force’s proposal stood out:

Because a key aim of Agility Prime is to work with commercial industry, there are currently no plans to modify the design of the orbs for military use or arm them for strike missions. “We will not put any military unique requirements on them because the last thing you want to hear as a commercial backer of one of these companies is that the military is coming in and changing a vehicle away from a type that would have domestic use,” Roper said. “We want to create a supply chain in the U.S. that is dual commercial and military.”

In other words, the Air Force wants to buy these unmodified from commercial civilian companies, both to save money and speed utilization. They have issued the general specs for the two types of vehicles they want (one larger than the other) and are accepting bids from private companies for delivery.

If true and if the Air Force sticks to this policy (which is essentially the approach I advocated for NASA in my 2017 policy paper Capitalism in Space), they hope to have these vehicles flying operationally by 2023, and at a cost of only “a few hundred thousand dollars to a few million dollars per unit.”

Midnight repost: NASA, the federal budget, and common sense

11:59 pm

The tenth anniversary retrospective of Behind the Black continues: Tonight’s midnight repost is actually two. First we have what might have been my most telling report for John Batchelor, aired in late July 2013. In that appearance I was quite blunt about my contempt for the politicians in Washington and the fake space program they had been foisting on the American public for decades. As I said,

What both those parties in Congress and in the administration are really doing is faking a goal for the purpose of justifying pork to their districts, because none of the proposals they’re making — both the asteroids or the moon — are going to happen.

Here is the audio of that appearance [mp3] for you all to download and enjoy. For reference, these are specific stories from then that I am discussing:

That rant makes for a perfect lead in to an essay I wrote in late 2011, outlining what I would do if I was in a position to reframe NASA’s budget. Everything I said then still applies. And that it does is a great tragedy, in that it means that nothing has changed, and our federal government continues to gather power while bankrupting the country.

————————–
NASA, the federal budget, and common sense

Let’s be blunt: the federal government is broke. With deficits running in the billions per day, there simply is no spare cash for any program, no matter how important or necessary. Nothing is sacrosanct. Even a proposal to cure cancer should be carefully reviewed before it gets federal funding.

Everything has got to be on the table.

Update on Starship test program: First tests for prototype #5

9:11 am

Link here. Lots of good information, including details about the growing assembly line of new Raptor engines.

Meanwhile, labeled “27”, the engine – logically assumed to be Raptor SN27 – SpaceX has just installed on Starship SN5 is also of interest. On top of Musk’s recent confirmation that SpaceX is already building Raptor SN30 (probably SN31 or SN32, now), SN27’s assignment to Starship SN5 confirms that the company has managed to complete (and test) at least one next-generation engines every other week since the first full-scale engine shipped to McGregor, Texas in February 2019.

For a brand new engine as complex as Raptor, that’s an impressive production milestone. Per Musk, the end-goal is to produce at least one Raptor per day in the near term – a necessity given that each Starship and Super Heavy booster pair will require at least 37 engines. To feasibly build a fleet of tens – let alone hundreds or thousands – of Starships and boosters, one engine per day is arguably the bare minimum required just for early orbital launch attempts and initial operations.

They hope to start static fire tests, with prototype #5 by July 8th. If these go well they will likely follow soon thereafter with the first short vertical hop.

Midnight repost: Obama’s legacy of hate

11:59 pm

The tenth anniversary retrospective of Behind the Black continues: This essay was posted originally on August 19, 2019. It quite correctly predicts the looting, rioting, and violence going on now against monuments honoring past American heroes and defenders of freedom. It also correctly predicts that this looting, rioting, and violence is as yet only beginning. Be prepared for far worse, especially if you wish to defend the honor of the American dream of individual freedom, personal responsibility, and rule by law.

——————
Obama’s legacy of hate

Of all of Obama’s achievements, probably the one that is going to ring down the decades the longest and maybe do the most to destroy the United States and western civilization was his willingness to either endorse or refuse to condemn the use of slanders and lies to advance the political power of his Democratic Party and the left.

The most obvious example of this were the false accusations by top Democrats that the Tea Party protesters against Obamacare were “racist”, despite zero evidence. (I speak from personal experience, as I was involved in Tea Party groups in both the DC and Tucson areas.) Obama was in a position to tamp down this hateful and dishonest rhetoric. Instead, he allowed members of his administration to encourage it.

This political tactic has now become pervasive and dominant throughout the Democratic Party and its minions in the mainstream press. This fact became especially evident to me this past weekend, during a demonstration in Portland by a group called the Proud Boys. This group was formed in 2016 in reaction to the modern political leftist pressure forcing Americans to adhere to leftist dogma. From their own webpage:

Midnight repost: “We stand for freedom.”

6:01 pm

The tenth anniversary retrospective of Behind the Black continues: This essay, portions of which was adapted from the fourth chapter of Genesis: The Story of Apollo 8, was posted originally on May 25, 2011, the fiftieth anniversary of Kennedy’s speech to Congress where he committed the nation to landing a man on the Moon by the end of the decade.

It seems fitting to repost on July 4th, Independence Day.

————————————

Kennedy's speech

“We stand for freedom.”

Fifty years ago today, John Kennedy stood before Congress and the nation and declared that the United States was going to the Moon. Amazingly, though this is by far the most remembered speech Kennedy ever gave, very few people remember why he gave the speech, and what he was actually trying to achieve by making it.

Above all, going to the Moon and exploring space was not his primary goal.

Rocket Lab launch failure

2:31 pm

Electron 34 seconds from launch

UPDATE: Mere seconds after I uploaded the post below, Rocket Lab announced that something had gone wrong late in the launch, resulting in the loss of all seven satellites.

This failure is the company’s second since their first test launch attempt. It will certainly prevent them from their goal this year of monthly launches.

The failure also changes the launch standings below. Rocket Lab is no longer among the leaders, and the U.S. leads China 16 to 14.

The original post:
—————————
Capitalism in space: Rocket Lab today successfully completed the thirteenth launch of its Electron rocket, placing seven smallsats into orbit.

The picture above, captured from their live feed 34 seconds before launch, is most amusing because of the white sheep and black cattle grazing in the foreground.

This launch, three weeks after their previous launch, was their fastest turn-around so far. They made no attempt this time to recover the first stage, but noted that they plan to do so on their seventeenth launch, four launches from now.

The leaders in the 2020 launch race:

14 China
10 SpaceX
7 Russia
3 ULA
3 Rocket Lab

The U.S. now leads China 17 to 14 in the national rankings.

Kate Smith – God Bless America

1:14 pm

The modern hate-mongers have attempted to cancel Kate Smith, not because she did anything wrong but because her breath-taking performance of this song, done repeatedly in all venues during her lifetime, infuriates them.

What isn’t often played, but is included in this version, is the opening verse:

While the storm clouds gather far across the sea
Let us swear allegiance to a land that’s free
Let us all be grateful for a land so fair
As we raise our voices in a solemn prayer.

I will always swear allegiance to freedom. May my country always consider itself among the ranks of free nations.

This short film appears to blend the song’s first performance in 1940, when the U.S. was not yet in World War II, with footage showing Americans of all stripes, listening. The scenes are staged, using Hollywood actors (including future president Ronald Reagan), but the feelings and thoughts expressed are all sincere and real.

The Declaration of Independence

11:01 am

On this day, when we celebrate the founding of the United States — a nation that for more than two centuries has been a beacon of liberty to the entire world — it is the obligation of every American to reflect again on the opening words of the Declaration of Independence.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.

This is what our Founding Fathers gave to us, the right to pursue our own personal happiness, in freedom.

What do the rioters and protesters during the past month offer? What do they propose for future generations, as they out of blind hatred tear down statues of Thomas Jefferson, George Washington, Abraham Lincoln, and numerous war heroes who fought for this ideal?

I think too few Americans are asking these questions. I ask them, and demand that everyone else do as well. I think just asking them will help clarify the situation for all.

How Beautiful We Were

8:01 am

For Independence Day, I think this poem is worth reading to remind us what kind of country was bequeathed to us, and created, by the Founding Fathers two hundred and forty-four years ago.

It begins like so:

A short list. In no particular order.

We told our children that any child could grow up to be President. And then we made it come true.

We had car shows, boat shows, beauty shows and dog shows.

We ran robots on the surface of Mars by remote control.

Our women came from all over the world in all shapes and sizes and hues and scents.

We actually believed that all men are created equal and tried to make it come true.

Everybody liked our movies and loved our television shows.

We tried to educate everybody, whether they wanted it or not. Sometimes we succeeded.

We did Levis.

We held the torch high and hundreds of millions came. No matter what the cost.

We saved Europe twice and liberated it once.

We believed so deeply and so abidingly in free speech that we protected and honored and, in some cases, even elected traitors.

We let you be as freaky as you wanted to be.

Read it all, to remind yourself of the refreshing possibilities that freedom bestows. It truly allows everyone, as it says at the base of the Statue of Liberty, to breathe free.

Midnight repost: The Fantasy of Extreme Weather

11:59 pm

The tenth anniversary retrospective of Behind the Black continues: The science described in this essay, posted originally on April 11, 2013 remains even today entirely accurate. Worse, the story illustrates the exact same kind of obtuse refusal to deal with reality that has put us today in the midst of a panic over a relatively minor seasonal virus.

Unfortunately, the links to the first two articles that I reference no longer work.

—————————–
The Fantasy of Extreme Weather

This week there were three stories describing new research proving that global warming is going to cause an increase in the number and violence of extreme weather events. Each was published in one of the world’s three most important scientific journals.

Sounds gloomy, doesn’t it? Not only will extreme heatwaves, cold waves, and droughts tear apart the very fabric of society, you will not be able to drink your soda in peace on your next airplane ride!

However, one little detail, buried in one of these stories as a single sentence, literally makes hogwash out of everything else said in these three articles.

Thomas Jefferson — The meaning of the Declaration of Independence

6:01 pm

An evening pause: Tomorrow is the Fourth of July, in which lovers of freedom and individual rights celebrate the signing of the Declaration of Independence, where by this nation committed itself forever to providing its citizens “the right to life, liberty, and the pursuit of happiness.”

Those words were written by Thomas Jefferson. In tonight’s evening pause, Steve Edenbo as Thomas Jefferson recites Jefferson’s thoughts on the meaning of his own words, taken from a letter he wrote just prior to the 50th anniversary of that signing in 1826, and mere weeks from his death.

May true Americans never stop honoring these words, and that man.

Blue Origin delivers its first BE-4 rocket engine

10:42 am

Capitalism in space: Blue Origin this week delivered its first BE-4 rocket engine to ULA, for use in ULA’s new Vulcan rocket.

This engine is still a test article and is not yet flight-worthy.

“The engine delivered is the first pathfinder engine to be mated with the Vulcan Centaur and will support ULA’s testing,” a Blue Origin spokesperson told SpaceNews. “We are planning on delivering the second engine in July.” A pathfinder is a development engine. Blue Origin has not said when a flight-qualified engine will be delivered.

…ULA set a 2021 target to fly its first Vulcan Centaur mission and needs two production-quality engines to build the launch vehicle for that mission. Flying Vulcan Centaur in 2021 is an imperative for ULA as it tries to win one of two contracts that the U.S. Space Force will award this summer to launch dozens of national security satellites between 2022 and 2027.

According to sources, frustration has been mounting at ULA as the company’s future is tied to the success of Vulcan Centaur and there is no room for error when it comes to the main engine.

I empathize with ULA’s frustration. The pace of development at Blue Origin has seemed incredibly slow in the past two years. They had begun static fire tests in 2018, and then — beginning with ULA’s decision to buy the BE-4 for Vulcan in May 2018 — for more than a year there was no news. It wasn’t until August 2019 that they announced completion of the first full power test. Even then, it took another whole year before they got to this point now, where they were willing to deliver a first test engine to ULA.

Building a new rocket engine is not simple, so these delays could be entirely reasonable. At the same time, the company’s overall pace in accomplishing anything has been glacial. For example, in the past three years it has repeatedly not delivered on its promises to start flying humans on its New Shepard suborbital capsule. Four months ago, in their most recent promise, they said they would need three more unmanned test flights of New Shepard before they’d put humans on it, and that all those flights (including the manned one) would occur this year. Yet nothing has happened since.

While I truly want Blue Origin to succeed, one must cast a cold eye on what is really happening. If they wish to really compete with SpaceX they have got to pick up their pace.

Midnight repost: Behind the Black

11:59 pm

In celebration of the tenth anniversary the Behind the Black, I will each evening at midnight this month repost an earlier essay or article posted on the website sometime during the past ten years. Since I have posted more than 22,000 times since I started this website in July of 2010, I have plenty of good stuff to choose from. The thirty reposts over the next month will highlight some of the best.

We begin with what is really the only Easter Egg on Behind the Black, as it has sat as a unheralded link dubbed only Behind the Black on the main page since the website’s beginning. That link takes you to the following essay, excerpted and adapted from the final afterword in the paperback edition of my book about the Hubble Space Telescope, The Universe in a Mirror.

It explains much about my goals in all that I write.
————————————
Behind the Black

At the end of the last spacewalk during this last servicing mission to Hubble, astronaut John Grunsfeld took a few moments to reflect on Hubble’s importance. This was Grunsfeld’s third spaceflight and eighth spacewalk to Hubble, and no one had been more passionate or dedicated in his effort to get all of Hubble’s repairs and upgrades completed.

“As Arthur C. Clarke says,” Grunsfeld said, “the only way of finding the limits of the possible is by going beyond them into the impossible.”

For most of human history, the range of each person’s experience was of a distant and unreachable horizon. This untouchable horizon defined “the limits of the possible.” No matter how far an individual traveled, there was always a forever receding horizon line of unknown territory tantalizingly out of reach before him.

Firefly honors the man who saved it from bankruptcy

9:37 am

Capitalism in space: Firefly Aerospace yesterday found a very unusual and entertaining way to celebrate the 43rth birthday of Max Polykov, the investor who purchased the company during bankruptcy proceedings and then rehired everyone so that the company could come back from the dead.

They decided to use one of their rocket engines to light the candles on his birthday cake. I have embedded the video of this effort below the fold. It is very clear that everyone at Firefly is immensely and sincerely grateful to Polykov for saving their company, which right now is among the leaders in the race to be one of the new rocket companies to meet the needs of the burgeoning new satellite industry.

SpaceX’s reusable first stages and their dramatic impact on the bottom line

9:15 am

This article by Eric Berger at Ars Technica outlining the status of SpaceX’s fleet of reusable first stages contained this incredible fact:

On May 11, 2018, the company launched the first of its new “Block 5” version of its Falcon 9 rocket. This new version of the first stage incorporated all of the company’s previous performance upgrades to the Falcon 9 rocket while also maximizing its reuse. It worked—SpaceX has now flown two different Falcon 9 cores five times, and it may fly a first stage for the sixth time later this summer.

The success of the Block 5 rocket means that SpaceX has had to devote less time and resources to building Falcon 9 first stages. Since May 2018, it has launched 31 times on a Block 5 version of the Falcon 9 rocket—while using just 10 cores. Put another way, reuse has saved SpaceX the cost of 189 Merlin rocket engines, dozens of fuel tanks, and many complex avionics systems. [emphasis mine]

That is a lot of cost savings, which the company is not only using to cut its prices but also to reduce the cost of its Starlink launches. It appears SpaceX wants those launches, as much as possible, to use reused boosters in order to lower the overall cost of getting that internet constellation into orbit. This in turn will make it possible for them to charge less for the service, once they begin offering it.

Starship prototype #5 passes cryogenic test

8:40 am

Capitalism in space: SpaceX’s fifth Starship prototype #5 last night successfully completed a cryogenic test of its tanks, setting the stage for its first vertical test flight.

SpaceX’s Starship SN5 prototype performed a cryogenic proof test at the launch provider’s Boca Chica, Texas facility on Tuesday evening. The test marked a rapid recovery for SpaceX – managing to return to testing a month after the previous vehicle exploded on the pad.

The cryogenic proof is when the vehicle’s propellant tanks are filled with liquid nitrogen and pressurized to flight pressures. Then, hydraulic pistons (otherwise known as a thrust simulator) press against the base of the vehicle to mimic the force of a Raptor engine. The proof test will ensure that Starship SN5 is structurally sound ahead of testing with liquid oxygen and methane. Unlike oxygen and methane, nitrogen is inert and will not combust if something were to go wrong.

The article at the link gives a nice overview of the test program, and what is to come next.

Capitalism in space: SpaceX today successfully launched its first satellite for the Space Force, a GPS satellite.

It also successfully landed the first stage, which was on its first flight. This was also the 88th flight of the Falcon 9 since its inception in 2010, which now makes it the rocket with the most launches of any U.S. operational rocket, bypassing ULA’s Atlas 5, and doing it in about half the time.

The leaders in the 2020 launch race:

13 China
10 SpaceX
7 Russia
3 ULA

The U.S. now leads China 16 to 13 in the national rankings.

With Americans under attack where are Trump and the Republicans?

12:39 pm

For me, the most distressing part of the panic over COVID-19 has not been the rules, the mandates, the nullification of the Bill of Rights, and the shut down of normal life, all of which have been terrible, wrong-headed, and a disaster for our country.

What has distressed me the most is the gutless response by the nation’s so-called conservative Republican politicians. All of the panic and harsh rules and economic damage has been designed by the Democrats to hurt the reelection chances of Trump. Little of it has anything to do with stopping the virus, and in fact most are nothing more than symbolic gestures that can accomplish nothing.

Despite this, Republican elected leaders have acquiesced to the Democrats demands, almost across the board.

Consider my own state of Arizona. My governor, Doug Ducey, is Republican. Republicans also have majorities in both houses of my state legislature. Yet, they have either let the Democrats run the show, or have acted in ways that are indistinguishable from the worst dictators in New York and New Jersey. First Governor Ducey imposed and then extended a lockdown that has bankrupted many businesses in the state. Then, as he began to loosen that lockdown he ceded his power to the generally Democratically-controlled local governments, letting them impose their own odious rules in place of his. The result is that in most big cities in the state, the lock down did not really end, but got tightened with new rules mandating masks.

Yesterday he reinstated part of his lock down for another thirty days. And like Democratic governors in Michigan, Pennsylvania, California, and New Jersey, the new rules he imposed [pdf] were arbitrary and capricious, and will thus have little if any effect. Bars, gyms, indoor movie theaters, and water parks have to close until July 27th. Government and community pools however can stay open. So can restaurants, shopping centers, clothing stores, and many other venues that previously were considered “non-essential.” He also banned any gathering of more than fifty people, but exempted political demonstrations and religious services.

And why did he do this? It appears there has been an increase in COVID-19 cases in the past few weeks! That means (oh no!) the number of people either hospitalized or dying might skyrocket, and overwhelm the hospitals!

Masks = virtue signaling

8:22 am

This essay by Robert Pratt about the uselessness of masks to stop or slow the spread of COVID-19 has this very clarifying quote:

“When a person is infectious with a virus it is estimated that they may shed one hundred billion virus particles a day – that works out to 10 million per breath,” [Dr. John Lee, a former professor of pathology at a UK medical school] pointed out.

Given that the most common cloth masks in use by people have thousands of pores, holes between the fabric threads, several times larger than the width of a human hair and that a full thousand virus particles can fit through a space the size of a human hair side-by-side even laboratory controlled fit and use of a mask, conditions not present in actual life usage, does little to stop the spread of virus particles.

…If just a breath contains 10 million virus particles, the pressurized large release associated with a sneeze or cough is reasonably likely to be much greater and will put millions of virus particles straight through a mask as well as much more out the side perimeters of such.

So let’s summarize: The mask, worn for long periods, forces you to rebreath your carbon dioxide at higher levels than normal, lowers the oxygen content to levels that are considered unhealthy, and in the end can do little to block the virus. On top of this, if you unconsciously touch the front of your mask (such as to pull it down to talk to someone), and your hand had not been sanitized just beforehand, you have just taken the risk of placing the virus on the mask, at exactly the place you breath.

Sounds like a plan to me, eh?

Sierra Nevada starts installing thermal tiles on Tenacity

6:05 pm

Capitalism in space: Sierra Nevada has received and started to install the thermal protection tiles for its first Dream Chaser reusable mini-shuttle, dubbed Tenacity.

The Thermal Protection System (TPS) tiles are one of the major hardware components used on Dream Chaser and cover nearly the entire craft to protect it from the heat of the sun and the plasma regime during atmospheric reentry. The tiles can withstand the scorching heat of 1,650°C (3,000°F) and prevent the vehicle from being destroyed during reentry.

Dream Chaser has approximately 2,000 TPS tile compared to the 24,000 tiles used on the Space Shuttle. Dream Chaser is about 1/4 the size of a Shuttle Orbiter. The tiles on Dream Chaser utilize a room temperature vulcanizing (RTV) silicone to keep the tiles bonded to the vehicle at all times. The silicone can withstand high temperatures, making it ideal for use. Each of the tiles is tested by a mechanism that pulls on each one, helping avoid issues of the tiles falling off, which happened early in the Space Shuttle Program.

The company notes that the vehicle remains on schedule for a 2021 launch on a ULA Vulcan rocket.

Some quick and easy evidence proving masks are unhealthy

5:58 pm

The video below illustrates very simply and quickly the reasons masks are generally a bad idea, especially for anyone with any chronic respiratory disease that causes reduced lung function. What it shows that within your mask the levels of oxygen are routinely below OSHA’s recommendations. While a healthy person will not suffer significantly, wearing a mask for a long period of time will certainly lead to headaches and diminished function. For a person with asthma or chronic pulmonary disease the low levels of oxygen, combined with the higher levels of CO2 (which you are rebreathing) will eventually cause serious harm.

The video comes from this link, which includes similar demonstrations.

Wearing a mask is simply not supported by the science. There is no clear evidence it stops or even slows the spread of the Wuhan virus, and it carries with it negative medical consequences.

The negative social consequences need not be discussed. They are beyond counting.

Dragon capsule on ISS doing better than expected

10:47 am

Capitalism in space: The first manned Dragon capsule, presently docked to ISS, is doing better than expected according to NASA officials, who have also now set August 2nd as their target date for the return to Earth.

Tests of the solar panels and the capsule’s power systems have so far been “better than expected.” Besides these tests, they still have one other major in-orbit test.

On July 4, the space station crew will perform a habitability test with the craft, with four astronauts climbing into the capsule and practicing everyday activities like sleeping, hygiene tasks, as well as emergency procedures to see what it will be like for future crewed missions. On Demo-2, only two astronauts were on board for the trip but regular flights will carry at least four people, so this test will help inform astronauts on those future trips.
