Today’s blacklisted American: Doctor jailed for entering Capitol on Jan 6 and expressing opinions

12:35 pm

Simone Gold, in prison for having wrong opinions

Blacklists are back and the Democrats have got ’em: Simone Gold, one of the thousands of doctors who strongly objected to the federal government’s COVID policies during the Wuhan panic, has begun a six month jail sentence for “trespassing” during the January 6th 2021 protests at the Capitol.

While US officials tried to smear and marginalize Gold and her group, her actual jail sentence was linked to her participation in the January 6, 2021 Trump rally in the US Capitol. According to Gold, she proceeded to the Capitol building on that date, where police let her into the building with a group that did not use force; and she spoke to the crowd inside about medical freedom.

As a result, she was charged with trespassing, and sentenced to jail time. [emphasis mine]

Sri Lanka blocks docking of Chinese spy ship as requested by India

11:47 am

The new Sri Lankan government, at the request of India, has rescinded the permission granted by the previous government that would have allowed a Chinese satellite tracking ship to dock at one of its ports.

In a written request, the Sri Lanka Foreign Ministry told the Chinese Embassy in Colombo not to go ahead with the visit, said an official involved in the process. “The Ministry wishes to request that the arrival date of the vessel Yuan Wang 5 in Hambantota to be deferred until further consultations are made on this matter,” the request says.

Sri Lankan President Ranil Wickremesinghe assured political leaders on Friday that the visit will not go ahead as planned.

The previous government, recently overthrown by a citizen revolt because of its green policies that produced starvation and bankruptcy throughout the nation, had agreed to the docking, changing years of cooperation with India. Apparently the new government has decided to renew that Indian alliance.

India in turn wishes to limit China’s ability to spy on its own satellites and operations in space.

Mapping the break-up and impact of one of the first asteroid’s tracked from space to the ground

11:33 am

Computer simulation of asteroid break-up
Click for full figure.

By analyzing 600 scattered pieces recovered from a 20-foot wide asteroid that broke-up and landed in the Sudan in 2008, scientists have discovered that some surface pieces were able to reach the ground unscathed because they were on the asteroid’s protected aft as it plowed through the atmosphere.

This asteroid was one of the first ever discovered shortly before impact and then tracked as it hit the atmosphere and broke up, the pieces falling as meteorites. The image to the right, figure 4 of the paper, shows the computer simulation of the asteroid’s break-up, based on the data obtained by mapping the location of its pieces on the ground. From the press release:

“Because of the high speed coming in, we found that the asteroid punched a near vacuum wake in the atmosphere,” says Robertson. “The first fragments came from the sides of the asteroid and tended to move into that wake, where they mixed and fell to the ground with low relative speeds.”

While falling to the ground, the smallest meteorites were soon stopped by friction with the atmosphere, falling close to the breakup point, while larger meteorites were harder to stop and fell further downrange. As a result, most recovered meteorites were found along a narrow 1-km wide strip in the asteroid’s path. “The asteroid melted more and more at the front until the surviving part at the back and bottom-back of the asteroid reached a point where it suddenly collapsed and broke into many pieces,” said Robertson. “The bottom-back surviving as long as it did was because of the shape of the asteroid.”

No longer trapped by the shock from the asteroid itself, the shocks from the individual pieces now repulsed them, sending these final fragments flying outwards with much higher relative speed. “The largest meteorites from 2008 TC3 were spread wider than the small ones, which means that they originated from this final collapse,” said Jenniskens. “Based on where they were found, we concluded that these pieces stayed relatively large all the way to the ground.”

The location of the large meteorites on the ground still reflects their location in the back and bottom-back part of the original asteroid.

While there is a certain randomness in how any asteroid breaks up, this data will help scientists better understand the make-up of future meteorites they find. The bigger more widely scattered pieces likely came from the asteroid’s rear surface.

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.

Further damage to Curiosity’s wheels

10:14 am

Curiosity wheel comparison of damage
For the original images, click here for the top photo and here and here
for the bottom photo.

The photo comparison to the right, created from high resolution images taken by Curiosity on Mars two months apart, provides us a new update on the state of the rover’s damaged wheels. It shows damage on the same wheel that I have been tracking for several years.

The numbers indicate the same treads, or grousers as termed by the science team. The “+” sign indicates spots where new damage has occurred since the previous photo.

The top photo was taken on June 3, 2022, and was the first to show new damage in more than five years. The bottom photo was taken on August 6, 2022, and shows that another small piece on the same grouser has broken off during the past two months.

Other than this change, however, the rest of the grousers appear unchanged. Moreover, a comparison with an earlier image of this same wheel taken in the summer of 2021 shows that grouser #6 as well as the unnumbered one just below appear also unchanged.

The damage in grouser #5 however is still concerning, and reflects the increasing roughness of the terrain as Curiosity climbs higher and higher on Mount Sharp. Though the science team has been very careful since the rover’s first few years on Mars to travel around obstacles that could damage the wheels, it apparently is becoming harder to do so.

However, even if this wheel eventually loses all the metal between the zig-zag grouser treads, the science team has said it has “proven through ground testing that we can safely drive on the wheel rims if necessary.” The team as also said they do not think that is likely, at least not for a long time, and based on the rate of damage documented by these pictures, this appears very true.

India’s new SSLV rocket fails on first launch attempt

10:53 am

Delayed years because of India’s panic over the Wuhan flu, the first launch of that country’s new Small Satellite Launch Vehicle (SSLV) failed today when the rocket’s fourth stage apparently did not fire its engines properly.

The problem appeared to be the SSLV’s terminal stage, called the velocity trimming module (VTM). According to the launch profile, the VTM was supposed to have burnt for 20 seconds at 653 seconds after launch. However, it burnt for only 0.1 seconds, denying the rocket of the requisite altitude boost. Two satellites onboard the rocket – the primary EOS-2 Earth-observing satellite and the secondary AzaadiSAT student satellite – separated from the vehicle after the VTM burnt.

As a result, the two satellites were put in an orbit that was too low, which quickly decayed, destroying both.

Since this launch failed, I do not count it in the launch totals for 2022.

Considering that this was SSLV’s first launch, it was in that sense a test, and a failure therefore is not unexpected. India’s real problem is that the launch was delayed so long because of the Wuhan panic, thus allowing other competitors to catch up and pass India. While it is certain ISRO will try again, and eventually succeed, it will not get the market share it would have had, had it launched in 2020 as originally planned.

SpaceX raises another $250 million in investment capital

8:58 am

Capitalism in space: SpaceX in July raised $250 million in investment capital from five unnamed investors, bringing the total raised in 2022 to $2 billion.

Added to the amount brought in before this year, SpaceX has raised about $9 billion in private capital, most of which is focused on financing the development of Starship/Superheavy. When you add the $2.9 billion contract it won from NASA to develop Starship as a manned lunar lander, the company has raised about $12 billion to build this heavy lift rocket.

The numbers demonstrate several things. First, Wall Street is apparently very confident SpaceX will succeed in building the rocket, and then make a lot of money from it. Second, the numbers prove it shouldn’t cost $60 billion and two decades to design and build a heavy lift rocket, as NASA has done with its SLS rocket. SpaceX is doing it for less than a fifth of the cost, in a third of the time.

FCC decides to expand its power in space

8:18 pm

FCC: Now in charge of everything in space

The Federal Communications Commission (FCC) today voted to initiate what it calls a “Notice of Inquiry” to begin a policy review aimed at expanding its involvement and regulation of “space missions like satellite refueling, inspecting and repairing in-orbit spacecraft, capturing and removing debris, and transforming materials through manufacturing while in space.”

From the Federal Communications Commission’s press release [pdf]:

Today’s action continues this modernization effort as in-space servicing, assembly, and manufacturing capabilities – or “ISAM” – has the potential to build entire industries, create new jobs, mitigate climate change, and advance America’s economic, scientific, technological, and national security interests. ISAM missions take place on-orbit, in transit, or on the surface of space bodies. The FCC’s effort to open up this conversation dovetails with the Office of Science and Technology Policy’s recent release of a ISAM National Strategy.

This policy review is part of the FCC’s broad effort to update its rules for the new space age. For example, the FCC is taking significant steps to update its satellite rules. The FCC also adopted new rules to lay the groundwork for giving satellite launch companies ready access to spectrum for transmissions from space launch vehicles during pre-launch testing and space launch operations.

ISAM (In-space Servicing, Assembly and Manufacturing) refers to the final policy statement [pdf] of a working group in the National Science & Technology Council, created as part of the Office of Science and Technology Policy in the Biden administration. That policy statement outlined six strategies that the federal government needs to focus on to encourage American success in space. From its conclusion:

Strange terrain southwest of Jezero Crater

1:17 pm

Strange terrain near Jezero Crater

Cool image time! The photo to the right, cropped and reduced to post here, was taken on June 16, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists have merely label “landforms.”

I instead call them strange. Clearly we are seeing exposed layering that surrounds the mesa in the middle of the image. This in turn suggests that the mesa top was once the surface of this whole region, and that region had been formed by the repeated placement of multiple sedimentary layers. Then, over time the surrounding terrain was eroded away, exposing those underlying layers.

Even so, some of the parallel lines do not appear to be layers, but striations etched into the ground. To get a better look, the white box marks the area covered by a full resolution close-up below.

Pushback: Forsyth County school board in Georgia sued for censoring parents during public comment

12:08 pm

The Forsyth County School Board

Bring a gun to a knife fight: The five elected members of the Forsyth County Board of Education in Georgia have now been sued for the repeated censoring of parents during their open comment period because the parents wished to read pornographic excerpts from books that school board had approved for use in school libraries.

The suit was filed by the Institute for Free Speech (IFS) for two parents, Alison Hair and Cindy Martin, as well as the independent parents organization called Mama Bears of Forsyth County.

Multiple district residents, including Mama Bears members and plaintiffs in the lawsuit Alison Hair and Cindy Martin, have used their time to read aloud from school library books they consider pornographic. Yet while these materials are available to kids in school, the Chair has cut off and banned speakers who read from them at Board meetings when he deems the language inappropriate or profane.

This catch-22 robs parents of the ability to confront board members with the very language they themselves consider inappropriate for children, such as graphic descriptions of sex acts. After plaintiff Alison Hair attempted to read one such passage at a March 15 board meeting, she received a letter signed by every member of the Board of Education prohibiting her from participating in any future meetings until she provides a written guarantee that she will abide by the Chair’s directives. The Board, however, cannot require that citizens sacrifice their First Amendment rights as a precondition for participating in meetings, the lawsuit explains. [emphasis mine]

You can read the complaint here [pdf]. The facts of the case are very clear: the board members, led by board chairman Wesley McCall, have been abusing their power to silence any criticism. They are also doing whatever they can to prevent parents from revealing the queer and obscene content contained in school library books that the board members have approved for children, as well as creating rules that make removing these books practically impossible.

Curiosity celebrates ten years on Mars

9:31 am

Curiosity's location in Gale Crater

Sometime today the rover Curiosity will celebrate its tenth anniversary on Mars. The oblique graphic of Gale Crater above, first released by the science team shortly before landing in 2012, has been further annotated with a red line to show the rover’s journey since then. As noted by Scott VanBommel, Planetary Scientist at Washington University, today on the science team’s blog:

As we the science and engineering teams have aged this last decade, so has Curiosity. The toll of ten years and nearly 28.5 km [17.7 miles] of Mars driving shows with every MAHLI wheel imaging activity, with less energy available for a plan, and with aging mechanisms. This is the life of a Mars rover. Spirit and Opportunity were no different, yet they persisted and paved the way scientifically and technologically for the rovers of today. Curiosity has made numerous scientific discoveries during these ten years, emphasized by the over 500 science team publications, with many more ahead as we continue our ascent and exploration of Gale crater and Mount Sharp.

I look forward to the next ten years.

Despite that aging, Curiosity’s general condition appears quite excellent, with its wheels the greatest concern but generally holding up. Based on the last ten years, the rover is likely to remain operational for at least ten more years, if not longer.

In the more immediate future, the rover is only days away from getting its first good look down into Gediz Valles, that canyon on the graphic above that it has been traveling towards since day one.

A good review of five of Curiosity’s biggest discoveries using its sample analysis instrument can be found here.

Virgin Galactic once again delays commercial suborbital operations

9:08 am

Capitalism in space: In releasing its quarterly report, Virgin Galactic yesterday revealed that it is once again delaying the start of commercial suborbital operations, pushing back from the first quarter of 2023 to the second quarter.

In an earnings call, company executives said that the latest delay was not directly related to supply chain and staffing problems it blamed for the previous delay. Instead, refurbishment work on its WhiteKnightTwo plane, VMS Eve, was taking longer than planned. “The driver is around the amount of time it is taking us to accomplish the work scope on Eve,” said Michael Colglazier, chief executive of Virgin Galactic. “We did not plan the full amount of time that’s been needed to get this work accomplished.”

Company officials also said they are shifting its customer emphasis, now focusing much more on “private and government researchers.” Let me translate: The public is not buying tickets, so Virgin Galactic hopes to convince the government to keep it afloat instead.

I predict this company will likely never fly any customers, and it appears the stock agrees, with the stock plunging in value, from $8.25 to $6.95 in less than a day.

Astra cancels all launches with its Rocket 3.3 rocket

9:01 am

Capitalism in space: Astra yesterday announced that it has canceled all further launches with its Rocket-3.3 rocket, and will instead focus on developing a larger version, dubbed Rocket-4, which it says will begin test flights in 2023.

The company says that it will no longer fly the Rocket 3.3 and move on to its larger Rocket 4 vehicle that it announced in May. One change is that the payload performance of the new rocket has doubled to 600 kilograms. Kemp didn’t disclose details of the design change other than an upgrade to its upper stage engine. Rocket 3.3, by contrast, had a payload capacity of no more than 50 kilograms.

“The feedback that we were getting from some of the larger constellation operators was that satellites were getting larger,” he said. Discontinuing the existing Rocket 3.3, he said, allowed the company to focus its resources on the new launch system, including increasing its payload capacity.

Essentially, Astra has left the field and is at present no longer an operational smallsat rocket company. It is also likely that its announced schedule for its upgraded rocket will not be met. Thus, expect customers to shift to other launch providers able to launch satellites, such as Rocket Lab and Virgin Orbit.

Not surprisingly, the company’s stock plunged soon after this announcement.

SpaceX launches South Korea’s Danuri lunar orbiter

4:50 pm

SpaceX today successfully launched South Korea’s Danuri lunar orbiter, also called the Korea Pathfinder Lunar Orbiter.

The first stage completed its sixth flight, landing on a drone ship in the Atlantic. The fairings completed their fourth flight.

Danuri is now on its way to the Moon, with a planned arrival in lunar orbit on December 16, 2022. It carries six instruments, one of which was developed by NASA. The spacecraft, while designed to study the Moon, is primarily a technology test mission laying the groundwork for more sophisticated interplanetary South Korean missions. More information about the mission can be found here.

The leaders in the 2022 launch race:

34 SpaceX
28 China
10 Russia
6 Rocket Lab
5 ULA

The U.S. now leads China 49 to 28 in the national rankings, and the entire world combined 49 to 45. With this launch American private enterprise has now surpassed the entire launch total for all of 2021, and has the most launches for the U.S. since 1967, when it completed successfully 57 launches.

China launches “reusable experimental spacecraft”

4:02 pm

According to the official Chinese press, China today successfully used its Long March 2F rocket to place into orbit a “reusable experimental spacecraft.”

To say the information provided was terse is to be extravagant. This is it:

After a period of in-orbit operation, the spacecraft will return to its scheduled landing site in China. It will test reusable technologies and in-orbit service technologies as planned during its flight, providing technological support for the peaceful use of space.

It appears, based on the size of the rocket, that this spacecraft is likely a copy of Boeing’s X-37B.

The leaders in the 2022 launch race:

33 SpaceX
28 China
10 Russia
6 Rocket Lab
5 ULA

The U.S. still leads China 48 to 28 in the national rankings, and the entire world combined 48 to 45.

These numbers should change within the next half hour, as SpaceX is about to launch another rocket.

Glacial flows pushing out through a Martian crater rim

12:51 pm

Wider view of 6-mile-wide crater
Click for full image.

Today’s cool image once again illustrates how Mars is far from a waterless planet. Instead, there is strong evidence that water ice can be found across most of the Red Planet’s surface, excluding the equatorial regions lower than 30 degrees latitude.

The photo to the right was taken on September 11, 2021 by the wide view context camera on Mars Reconnaissance Orbiter (MRO). It shows a 6-mile-wide unnamed crater on Mars, located at 35 degrees south latitude, with what appears to be a glacier in its interior, flowing to the southwest towards several breaches in the crater’s southwest rim. Several of those breaches now sit higher than the flow, suggesting that the glacier itself was once higher and flowed out of those gaps. Now the level has dropped, and the only place the glacier exits the crater is the central gap at the center of the white rectangle.

That white rectangle marks the area covered by a recent MRO high resolution image, taken on March 29, 2022 and cropped and reduced to post below.

Today’s blacklisted American: Supreme Court Justice Thomas forced to quit as lecturer at GWU

11:40 am

Clarence Thomas: Banned at amazon
Supreme Court Justice Clarence Thomas: driven out
as a lecturer at George Washington University

Blacklists are back and our future law students love ’em: Faced with a petition signed by 11,000 individuals demanding he be fired, Supreme Court Justice Thomas has resigned as a lecturer at George Washington University (GWU).

Thomas has been a lecturer at the school since 2011, but has now been removed as faculty from its website. His decision not to return to teaching comes in the wake of protests against conservative supreme court judges following the overturning of Roe v. Wade in June 2022.

The school was hit by a petition calling for the removal of Thomas, with more than 11,000 signatories. But George Washington University is home to just 1,600 students, and bosses there defended Thomas, insisting he was entitled to his views. [emphasis mine]

The highlighted words illustrate something significant: The bulk of the petition’s signers were not from George Washington University. However, though the school had apparently supported Thomas during this affair, we do not know how many of its 1,600 students signed the petition. What we do know is that there did not seem to be much public support for him from those students.

It is hard to fathom any law student not wanting to meet in person and hear the legal opinions of a Supreme Court justice, no matter where he or she stands on the political spectrum. To try to block such lectures reveals a shocking close-mindedness and hostility to rational thought. The language of the petition illustrates this, filled with false statements, ad hominen attacks, and complete intolerance of other points of view:

Axiom signs deal with New Zealand

9:52 am

Capitalism in space: The private space station company Axiom has now signed a deal with New Zealand to permit its citizens to propose and fly experiments on future Axiom missions, both to ISS and to Axiom’s own space station, scheduled for launch beginning in ’24.

This is the fourth international commercial agreement Axiom has signed since May, with Italy, Hungary, and the UAE the signatories in the previous deals. The UAE deal also included the launch of a UAE astronaut to ISS for a six month flight.

Axiom hopes to launch its first module to ISS in ’24, with later modules eventually allowing it to undock its section to fly as an independent station when ISS is retired.

Environmentalists opposed to Starship at Boca Chica appeal dismissal of their lawsuit

9:45 am

Environmentalists from the Sierra Club and one Texas Indian tribe have now appealed the dismissal of their lawsuit aimed at blocking further tests or launches of Starship and Superheavy by SpaceX at its Boca Chica facility.

The Sierra Club and the Carrizo/Comecrudo Tribe of South Texas jointly appealed the 445th District Court’s decision July 7 to dismiss a lawsuit concerning SpaceX testing of its next-generation Starship vehicle closing nearby Boca Chica Beach, the coalition said July 28. In the dismissal, Judge Gloria Rincones argued there is “no private right of enforcement” concerning the beach access, according to KRGV.com (opens in new tab). The dismissal took place over the appellants’ protests that closing the beach violates the Texas state constitution, along with access rights by traditional groups.

The Sierra Club’s Brownsville organizer, Emma Guevara, stated the appeal is taking place because the beach is closed weekly to allow “a billionaire [to] launch deadly rockets near homes and wildlife.”

Citing a fireball that briefly and unexpectedly engulfed Starship during testing July 12, Guevera said her family was “forced” to hear the noise, which “launched without any warning for the public.” [emphasis mine]

My my, what a horror! I suppose everyone must stop what they are doing because Guevera and his family might be inconvenienced. And who cares if the lawsuit prevents thousands of south Texas citizens from having jobs and a thriving economy? It is more important Guevera doesn’t have to hear loud noises.

The lawsuit claims that allowing SpaceX to periodically close access to the nearest beach violates the state’s constitution, despite laws passed by both the local and state legislatures allowing for these closures.

Next private SpaceX manned targeting December launch

9:31 am

Capitalism in space: SpaceX is now planning to launch in December the next private manned Dragon orbital mission, dubbed Polaris Dawn, and led by billionaire Jared Isaacman, who led the previous private Inspiration4 mission in September 2021.

Polaris Dawn is the first of three separate crewed launches, all of them funded by Isaacman. This first effort will see Isaacman flying a SpaceX Dragon spacecraft alongside Sarah Gillis, Anna Menon and Scott Poteet. (Both Gillis and Menon work at SpaceX.) The second launch aims to use a Dragon while the third is scheduled as the first crewed mission for Starship, SpaceX’s next-generation spacecraft.

…Among the mission’s aims is the first spacewalk, or extravehicular activity (EVA), of a private astronaut. The crew will use SpaceX-developed EVA suits for the effort. Crew Dragon will be depressurized for the spacewalk in a similar way that NASA’s Gemini capsules were in the 1960s, requiring all crew members to wear suits designed for a vacuum environment.

By not flying to ISS, Isaacman and SpaceX avoid the high fees NASA charges as well as its extensive requirements.

By remaining in orbit however the length of the mission will be limited to only a few days, rather than weeks. Thus, it underlines the growing need for private commercial space stations, not controlled by the government.

Lucy science team ends attempt to deploy solar array

9:12 am

Lucy's planned journey
Lucy’s planned mission, the yellow dot indicating approximately
its present position. Click for full image.

The Lucy science team has decided to end further attempts to fully deploy one of the spacecraft’s two solar arrays, leaving it just short of fully deployed.

On seven occasions in May and June, the team commanded the spacecraft to simultaneously run the primary and backup solar array deployment motors. The effort succeeded, pulling in the lanyard, and further opening and tensioning the array.

The mission now estimates that Lucy’s solar array is between 353 degrees and 357 degrees open (out of 360 total degrees for a fully deployed array). While the array is not fully latched, it is under substantially more tension, making it stable enough for the spacecraft to operate as needed for mission operations.

The press release announcing this decision is horribly written. First, it buries this decision to the release’s last three paragraphs so that it can rave about the brilliance of Lucy’s engineers and scientists in solving the overall problem. Second, it never actually states that this is the decision that has been made. It implies it.

Regardless, it appears the engineers are satisfied that the almost fully deployed array will hold its position for the rest of the mission. They have decided that the risk of trying to fully deploy it is greater than the risk of having it slightly open.

China launches three satellites with Long March 4B rocket

11:41 pm

China early on August 4, 2022 (China time) successfully placed three satellites in orbit, including a climate satellite it claims will do “carbon monitoring, survey and monitoring of terrestrial ecology and resource, major national ecological projects monitoring and evaluation.” No information at all was released about the other two satellites, both of which were probably cubesats.

This launch actually occurred prior to the Electron launch from Rocket Lab.

Rocket Lab launches second NRO surveillance smallsat in three weeks

10:14 pm

Capitalism in space: Rocket Lab today successfully used its Electron rocket to place its second National Reconnaissance Office (NRO) surveillance smallsat into orbit in just over three weeks.

For Rocket Lab, this was the sixth launch in 2022, which matches its previous annual high, achieved in both 2019 and 2020. It should easily top that record before the year is out.

The leaders in the 2022 launch race:

33 SpaceX
26 China
10 Russia
6 Rocket Lab
4 ULA

American private enterprise now leads China 47 to 26 in the national rankings, and the entire world combined 47 to 42.

Two more American launches are scheduled in the next day. If both are successful, the U.S. will have exceeded its entire launch total for 2021 (48) in only a little more than a half year, and completed the most successful launches since 1967.

The second half of the year should actually be as active as the first half, with three more American smallsat rocket companies (Firefly, Relativity, and ABL) pushing hard for their first successful launches before the year is out, thus joining the already operational smallsat rocket companies Rocket Lab, Virgin Orbit, and Astra.
