• Russia’s Luna-25 lander delivered to launchpad in Vostochny

The official launch date has not been released, but it is now expected to be in mid-August.

 

• Vast hires former NASA astronaut as “advisor”

The job description implies retired astronaut Garrett Reisman is only a consultant.

 

• Japan announces August 26, 2023 launch date for next H2A rocket launch

Though the payload includes a Japanese lunar lander as well as an X-ray space telescope, the real importance of this announcement is that it tells us that Japan’s investigation into its H3 rocket failure has learned enough to no longer block H2A launches as well.

• DARPA’s Blackjack smallsat test constellation reduced from 20 to 4 satellites

The project, started in 2017, was to prove smallsat could provide the military what it needed faster and cheaper. It appears DARPA has concluded, after launching four satellites, that such a technology test program was no longer needed. Commercial space has proved the point, hands down, far faster than the government.

 

• China’s Tianwen-1 Mars Orbiter snaps another picture of itself over the Mars north pole

Not particular interesting, but it allows China to tout its work.

 

• Rumors suggest Dish and Echostar are considering a merger

From Jay: “Both companies are owned by the same guy. They originally split in 2008.” Since the sources are anonymous, we must treat this story with some skepticism.

Your host is under the weather today, so no political column. Hopefully I’ll feel better later tonight or tomorrow.

• Firefly gives sneak peek at its Miranda engine, being developed to replace the Russian engines in Northrop Grumman’s Antares rocket

Not much there but an out-of-focus view partly blocked by a workman wearing a t-shirt with the engine’s schematic on its back.

 

• Blue Origin to launch Iranian satellite?

The article, unfortunately behind a paywall, is about Iran getting an extension from regulators to launch a long delayed communications satellite. Its headline adds “Blue Origin launch in 2024,” which is the real story. As Jay correctly notes, “What on Earth are they talking about? Using Blue Origin to launch an Iranian satellite? Are they out of their minds? Iran is our enemy.” In searching the web, I could only find one hint (which I can no longer find) that Blue Origin offered to do the launch (though it still lacks a rocket to do so), but no indication that any deal with Iran was ever signed.

 

• China predicts it will reach 70 launches in 2023, a new record

With only 24 launches in the first half of the year, China would almost have to do that number twice over in the second half to meet this target. Since it historically has launched at a much higher pace in November and December, this is not impossible, though still difficult.

 

• Rumors that Chinese pseudo-company Landspace has financial difficulties

Next week the pseudo-company will attempt for the second time the first orbital launch of a methane-fueled rocket, dubbed Zhuque-2. It sounds like a failure could shut the company down.

 

• Europe shifting more launches to SpaceX due to Ariane-6 delays

The article lists six payloads that have or will likely switch to the Falcon 9. That’s a lot of money suddenly flowing to SpaceX, from $200 million to $500 million, depending on price per launch. And it is all happening because Europe first denied the importance of reuseability and second moved too slowly in trying to compete. As Jay notes, “SpaceX did not choose to become a monopoly.”

• Seattle press goes ga-ga over Blue Origin pr event

The article touts the “thousands of jobs” Blue Origin will bring the city. It seems unaware the company’s accomplishments so far have been remarkably disappointing.

 

• Another Vega-C engine failure during static fire test

The test was part of the investigation following a failure of an identical engine during a Vega-C December 2022 launch. This new failure was on an engine that had been upgraded, so the European Space Agency has now begun an independent review. Vega-C will thus not resume launches this year.

 

• At international conference Russia offers other nations participation in its proposed Russian Orbital Station

A diagram of that station can be found here. As Jay quite correctly notes, “China does not want them, we don’t want them, and India signed the Artemis Accords. This new station is made up of leftovers from the ISS and one module that was never launched. Their program has become a side-show.”

• Rocket Lab plans back-to-back launches of its Electron rocket

The launch window for the first opens on July 14th, and they will attempt recovery of the first stage.

 

• PLD Space wins government contract from Spain to develop its smallsat rocket

The initial award is for 1.5 million Euros. The next phase could provide up to 40.5 million Euros more.

 

• India private rocket startup Skyroot completes carbon-fiber winding and curing of its first stage “motor case.”

This is for Skyroot’s orbital rocket, dubbed Vikram-1. The company has already successfully completed a suborbital test launch.

 

• The New York Times discovers, decades late, that India is no longer communist, and has a thriving private and competitive aerospace industry

I love it when these partisan Democratic Party news outlets suddenly peek outside their leftist bubble to report “scoops” on stories that have been evident for years.

 

• Chinese pseudo-company Landspace sets July 12th as its next orbital launch attempt for its Zhuque-2 rocket

If successful, it would be the first methane-fueled rocket to reach orbit. This launch will be the company’s second attempt

• Virgin Galactic completes its first commercial manned suborbital flight

My heart be still. Only two decades late, long after the big market has faded for suborbital tourism and shifted entirely to orbital flights.

 

• Firefly gets a launch contract from Lockheed Martin

This contract continues Lockheed Martin’s strong support for startup rocket companies, on top of its previous investments in Rocket Lab and ABL

 

• Europe’s Euclid cosmology space telescope ready for launch July 1, 2023 on SpaceX rocket

This is an example of a launch that SpaceX grabbed because Europe’s Ariane-6 rocket was delayed.

• Virgin Galactic announces the passengers on its first commercial suborbital flight scheduled for June 29, 2023

This flight is only about two decades later than promised by the company’s founder Richard Branson, who very successfully pumped and dumped his stock before the price crashed. It certainly doesn’t rate a full post, since suborbital flights so relatively boring compared to the increasing number of orbital passenger flights taking place these days.

 

• The modifications to Vulcan’s upper stage due to the test explosion in March

They will have to destack the first Vulcan to make the changes, which will delay the first Vulcan launch an undisclosed amount, possibly months.

 

• Egypt and China partnership delivers first jointly built satellites

The two satellites, built in China, will be assembled, integrated, and tested in Egypt, using facilities built with Chinese funding. More here.

 

• ESA and European companies endorse “zero debris” policy for satellites and orbital spacecraft

According to this commitment, by 2030 no European satellites or spacecraft will launch without a plan to de-orbit or be removed by an orbital removal company.

 

• Astronomers think they have discovered the heaviest black hole ever, 30 billion times the mass of the Sun

All together now: “The uncertainty of science!”

 

• PLD delays its next suborbital launch attempt until the fall to avoid the risk of forest fires at its Spanish launch site

The last launch aborted less than a second before launch because the umblical lines did not detach as planned.

 

• India names its Chandrayaan-3 lander and rover Vikram and Pragyan, due to launch in mid-July

These are the same names given to the lander and rover on the failed Chandrayaan-2 mission.

• UK rocket startup Skyrora begins engine tests

Skyrora has been around since 2018, but has yet to reach orbit. We shall see if this development leads to that first orbital launch.

 

• AST SpaceMobile successfully completes tests using an ordinary cellphone working with its BlueWalker-3 satellite

The tests achieved 10MB download speeds.

 

• ESA briefing this week on status of Ariane-6 provided no update on launch date

The lack of any schedule is not good, suggesting the final work required is going to take a longer than expected. This might also be why France and Arianespace have suddenly begun signing launch contracts with independent rocket startups. They realize they need to do whatever they can to generate some alternatives.

 

• Chinese pseudo-rocket company CAS-Space signs deal with French startup

It appears the French company acts as broker, finding rockets for payloads wanting to fly. China is now allowing it to sell space on CAS-Space’s rockets as well.

 

• NASA tweet: “Together with BoeingSpace, we are taking the necessary time to finalize the path forward for #Starliner’s Crew Flight Test.”

From Jay: “You can drop this story if you want. I included it since the people on Twitter are ragging on it.” I agree, the tweet is a joke, and thus deserves ragging. If by including it here we encourage more such ragging of NASA and Boeing then my job here is done.

• An analysis of the landing failure of Hakuto-R1

This is thirty minute presentation, which concludes that though there was a failure of the software, in the end the failure was due to management errors, including changing the landing site without doing sufficient simulations.

 

• Boeing CEO says company still committed to Starliner

Sounds good, eh? Don’t bet on it. The company is almost a billion dollars in the hole due to the extra costs incurred because the project’s failure, with no sign yet of any income in the near future.

 

• Delta-4 Heavy launch scheduled for tonight, at 3:29 am Eastern

This will be the first Delta-4 Heavy launch in almost three years. More significant, it will be ULA’s first launch in 2023, a number that is even lower that its low launch numbers of recent years. At this pace it will be a challenge for ULA to match its lowest launch counts of five, from ’19 and ’21. UPDATE: Scrubbed, reschedule 24 hours later.

 

• Anonymous source says Blue Origin will now require in-office work, five days per week

The source’s whining about this is amusing, but it also suggests once again the culture and management at Blue Origin is not the best.

 

• China claims it has a large alliance of space-faring nations who have agreed to partner on its lunar base

Except for Russia and the UAE, all are small time third world nations with no space infrastructure. Many have also not made a commitment, simply opened discussions. Russia will contribute little, and the UAE has a conflict as it also wants to participate in Artemis. U.S. law makes participating in both very very difficult, if not impossible.

 

• China’s state-run press deletes comments from professor claiming NASA had agreed to use China’s Queqiao lunar relay communications satellite

Either the professor was misinformed, or he revealed illegal negotiations by Biden’s NASA that NASA didn’t want revealed. If the latter, there was probably a frantic call made to China by the White House, begging them to censor this information, and China gladly obliged.

• Sierra Space awarded a Space Act Agreement by NASA commercial space development program

It was one of seven companies receiving similar unfunded support grants, including SpaceX, Blue Origin, Northrop Grumman, Vast, and others.

 

• China announces it will allow NASA and others to use its Queqiao lunar relay communications satellites

That’s nice, but U.S. law forbids NASA or any countries it works with to work with China. This announcement is simply a PR effort by China to make believe it works with others selflessly.

 

• Graphic showing all of China’s different pseudo-commercial rockets and engines, as of this date

Many of these have not yet launched, though most I expect will with time.

 

• Russia celebrates the 60th anniversary of the first female flight in space by Valentina Tereshkova by honoring her

According to Jay, she is still a member of Russia’s Duma (its congress), and voted for the Ukraine invasion. No wonder Putin gave her this award.

May everyone have a great weekend!

• Vast selects Impulse Space to provide the propulsion system for its first space station, dubbed Haven-1

This station is the one that Vast has hired SpaceX to launch as a single module.

 

• Bankers: ULA, Ball Aerospace, and Boeing’s space portfolio are being shopped around for sale

Unless you could get a really good price for their assets, right now I wonder why anyone would want ULA or Boeing, as neither seems well positioned to compete in the present space market, now or even in the near future.

 

• Video of today’s launch of China’s Long March 2D rocket

The panels falling from the rocket are not a mistake but intended. Used for insulation while on the launchpad, they are abandoned when no longer needed to save weight.

 

• Malaysian professor at Chinese university claims NASA agreed to use China’S Queqiao lunar communications satellites on its Artemis moon missions

Since there is a law on the books forbidding NASA or any government agency from working with China, this claim is almost certainly bogus. It is more likely China’s attempt to lobby an end to that law.

 

• Kuiper official urges governments to regulate the methods used by satellite makers to maneuver their satellites

I like Jay’s comment: “How many satellites does Kuiper have again? Zero. Damn arm-chair satellite companies!” The timing of this statement, a day after the WEF issued its proposed government guidelines for de-orbiting satellites, suggests Amazon supports that effort, but has a different approach as to how those rules should be implemented.

In other words, Amazon wants to dictate how others build their satellites. Or make it illegal for them to do so as they wish. Seems a great plan for eliminating one’s competition.

• Virgin Orbit’s 747 is stripped of the company logo

To be replaced by Stratolaunch’s colors.

 

• Diagram from ULA outlining the pattern of decay for orbital debris, depending on orbit

This diagram was posted in connection with a proposal from ULA’s CEO, Tori Bruno, suggesting a system similar to carbon credits to eliminate space junk. Bruno also suggests the U.S. should “kickstart” this program. The timing, the same day the WEF released its own space junk guidelines, suggests he is all-in on strong international regulation, along with the kind of scams (such as carbon credits) that this regulation always goes hand-in-hand with. It also suggests he wants to use that regulation to beat down his competitors, since on the open market ULA is failing miserably at this task.

• Some cumulative statistics for SpaceX’s various smallsat Transporter and rideshare launches

The total launches is 17, which have put up 676 satellites in total. To get a sense of the increasing pace of SpaceX launches, see this animation.

 

• ULA CEO Tori Bruno claims the root cause of the Centaur test explosion has finally been identified

He says in a followup tweet that “the super thin, high performance steel skin needs to be a little thicker near the top of the dome.” They plan to retest, which I suspect is going to impact the first Vulcan launch date.

 

• China breaks ground on third launchpad at its Wenchang coastal spaceport for its pseudo-companies

This pad is aimed at servicing “small solid rockets”, essentially former missiles that China has allowed its pseudo-companies to adapt for satellite launches.

• Astra shareholders agree to reverse stock split in order to prevent its stock from being delisted

In other words, if you owned one share that share could end up being equal to somewhere between 1/5th or 1/15th of one share. The goal of such a reverse split is to raise the value of one share to higher than a dollar, the minimum the stock market was insisting on or it would delist Astra.

 

• On June 7th astronauts on Tiangong-3 installed a new xenon tank for the propulsion system on the Tianhe module

The tank was apparently brought up on the most recent Tianzhou freighter, and transported to its proper place through the airlock on the Mengtian module.

 

• The upper stage from 2016 North Korea rocket launch burned up over the Southern Ocean on June 9, 2023

According to the link, there are now only three North Korean objects remaining in orbit, all from launches years ago.

 

• Stoke Space successfully completes another static fire test of its revolutionary engine design

Rather than building large engines releasing their energy through a single large nozzle, Stoke releases the energy through a ring of small nozzles. This test demonstrated the ability to adjust the thrust in different places on the ring, thus simulating the gymballing of a normal nozzle to steer the rocket.

• SpaceX’s Starlink wins Pentagon contract for satellite services to Ukraine

Terms were not released, but this contract is essentially the military’s recognition that if it wants Starlink available for use in the Ukraine it will have to pay for it. As Musk said several months ago, the freebie deal with SpaceX has to end.

 

• First Dream Chaser launch delayed to no early than the end of this year

This new delay appears mostly related to ULA’s problems in getting the launch rocket, Vulcan, operational.

 

• Tweet outlining activity launchpad construction activity at Cape Canaveral

I include this link because Jay thinks it is worth seeing, but it is written in the kind of typical Twitter shorthand that I find incredibly uninformative and confusing. All it does is hint at stuff without providing any real information.

 

• Analysis of Relativity’s Terran-R rocket says its launch price should be $55 million, though the early contracts are paying $45 million

The lower initial contract prices are nothing unusual. Satellite companies routinely get better prices on new rockets. Once established and proven the price then goes up. And at $55 million that price will still be competitive, and likely will soon drop once Relativity begins reusing parts, as it aims to do.

• ESA press release calls for private European companies to provide freighter service to ISS and future stations

This announcement is a followup on ESA’s new policy to emulate NASA by adopting my recommendations from my 2017 policy paper, Capitalism in Space by becoming a mere customer hiring its aerospace private sector rather than being the designer and builder of spacecraft and rockets.

• Virgin Orbit’s chief operating office gets lump-sum cash severance payment in bankruptcy auction

Other sources tell me that the company’s assets are going to sold off piecemeal, as no single buyer was found to buy it whole. Expect more news by tomorrow.

 

• Virgin Orbit’s 747 meanwhile completed another flight

This flight was probably done to satisfy the potential buyer, thought to be Stratolaunch.

 

• ESA looking for commercial companies to provide cargo services to ISS, followed by commercial space stations

It seems the European Space Agency (ESA) has finally decided to stop trying to build things and become customers of European companies. This is excellent news. It will be great to get some space competition from Europe.

 

• China wants its own pseudo-companies to provide a cargo ferrying service for China’s space station

It seems everyone is getting into the act, encouraging competition. China however will be hindered by the reality that the government there really controls everything. Its pseudo-private companies are only make-believe independent. In the end the government dictates everything.

• China’s Xichang spaceport brags that it had in 2022 zero injuries or casualties from rocket debris falling

This is one of China’s interior spaceports, so they apparently recognize that their rocket stages can fall on someone’s head, and are proud that in 2022 they avoided any such tragedies. Well, bully for them.

• Australian company gets approval to develop site for producing solid fuel and launching rockets

The company, Black Sky, appears a long way from actual launches.

 

• Video showing how equipment is moved from inside China’s Tiangong-3 station to outside without an astronaut EVA

Essentially they put the gear in the airlock, and then the robot arm, operated by an astronaut, pulls it out. From there however a spacewalk is usually required to install the gear, depending on what it is.

 

• Video taken by nearby bystanders of Long March 3B launch

“Nearby” is an understatement, especially considering this is a rocket using toxic hypergolic fuel. The videographer couldn’t have been more than a half mile away, and maybe as close as a quarter of a mile.

 

• FCC rules against Dish Network’s 5G plan, claiming it would interfere with Starlink

This decision illustrates the critical importance of acting fast in a competitive market. SpaceX moves fast, gets launched first, and thus automatically gets priority when conflicts occur with other systems that are only proposed.

 

• Space Perspective will offer high altitude balloon weddings in late 2024

During the launch a side insulation panel was ripped off, destroying one of the station’s two main solar panels and also allowing the station’s temperature to rise to unmanageable levels. The other main solar panel meanwhile failed to deploy in orbit because of a strap. Astronauts led by moonwalker Pete Conrad did a series of spacewalks to free the stuck panel as well as install a new umbrella-like cover to bring the station’s temperature down to the correct levels. These successes made it possible for three crews total to occupy Skylab over the next two years.
