Musk gives update on Starship/Super Heavy

8:11 am

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

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

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

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

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

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

10:24 pm

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

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

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

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

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

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

Rocket Lab successfully launches a commercial radar satellite

8:53 pm

Capitalism in space: Rocket Lab tonight successfully resumed launches after its launch failure last month by placing a a commercial radar satellite into orbit.

This was Rocket Lab’s third successful launch in 2020, so they don’t make the leader board. The leaders in the 2020 launch race:

20 China
14 SpaceX
9 Russia
4 ULA

The U.S. now leads China 23 to 20 in the national rankings.

SpaceX successfully launches Argentina satellite

4:37 pm

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

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

The leaders in the 2020 launch race:

20 China
14 SpaceX
9 Russia
4 ULA

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

SpaceX scrubs Starship prototype hop

3:32 pm

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

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

Confirmed: SpaceX plans two launches for tomorrow

1:02 pm

Capitalism in space: SpaceX has now confirmed that it will attempt two Falcon 9 launches tomorrow at its launch facility at Cape Canaveral, the first to launch 60 Starlink satellites at 10:12 am (Eastern) and the second to launch an Argentinian radar satellite at 7:18 pm (Eastern).

In the first launch the first stage, used once before, will attempt to land on the drone ship in the Atlantic. On the second launch the first stage, used three times previously, will return to Cape Canaveral for its landing attempt.

The live stream for both will be available here.

SpaceX will also tomorrow attempt a 500 meter hop of its sixth Starship prototype. The live stream of that can be seen here.

Meanwhile Rocket Lab has shifted its launch this weekend in New Zealand from tonight to tomorrow night at 11:05 pm (Eastern). The live stream will be aired here.

That means on August 30, 2020 there could be three American launches as well as another test flight of a new reusable rocket.

Note: Astra has delayed the first orbital test flight of its rocket to no early than September 10th due to poor weather in Kodiak, Alaska.

Another Chinese national arrested for spying

5:52 pm

The Department of Justice on August 25th arrested a Chinese national as he was trying to leave the country with classified military computer software.

U.S. Customs and Border Protection stopped Hu Haizhou, a researcher from the University of Virginia’s Department of Mechanical and Aerospace Engineering [who] also work[ed] for a Chinese military-linked university too, before he could board a flight to Qingdao, China, from Chicago’s O’Hare International Airport on Tuesday, said an FBI special agent in an 11-page affidavit filed on Friday in federal court in Virginia.

According to the agent, Matthew Rader, CBP investigators questioned Hu and searched his electronic devices, which revealed UVA-research-related files stored on his laptop, including “bio-inspired research simulation software code” developed by “Professor 1.” Bio-inspired research relates to studying the complexities of flying and swimming creatures in nature and applying that to manned flight or submersibles — often with military applications.

Hu “did not have lawful, authorized access to this material, and he admitted that Professor 1 would not want him to have it and would be upset to learn that HU possessed it,” the FBI said. The professor, who runs the multiuniversity Flow Simulations Group, has been developing this code over the last 17 years and is sponsored by the U.S. government’s National Science Foundation and the Office of Naval Research. The FBI special agent said that probable cause existed to charge Hu federally with fraud-related illicit computer intrusions and the theft of trade secrets.

More here.

These stories are beginning to sound repetitious, as they keep happening on almost a weekly basis. It appears that until the Trump administration the swamp in Washington had absolutely no interest for decades in protecting this nation from spying and the theft of military secrets from China or from anyone else.

Seems par for the course. At best our so-called elites are incredibly incompetent. At worst they have shown themselves to be traitors, with their loyalties aligned more with foreign powers than with the United States.

AI software beats real pilot in simulated dogfight

5:35 pm

The Terminator is coming: In a DARPA competition between a number of AI software teams, the finalist AI team, called Heron Systems, went up against a real F-16 pilot in a simulated dogfight and went undefeated, beating him five times in a row.

Heron Systems, a company with just 30 employees, had beaten out Aurora Flight Sciences, EpiSys Science, Georgia Tech Research Institute, Lockheed Martin, Perspecta Labs, PhysicsAI, and SoarTech to claim the top spot in the last of Defense Advanced Research Projects Agency’s (DARPA) AlphaDogfight Trials. This three-day event had started on Aug. 18, 2020.

The software then beat the real pilot.

There is a lot of blather on the website, though there is this interesting analysis by F/A-18 Squadron commander that in the end concludes that we are only a generation or two away from making all fighter pilots obsolete.

Or to look at it from another perspective, we are only a short time away from putting the ability to fight war entirely into the hands of computers and software, with abilities that humans will not be able to match.

Does no one but me see the potential problems with this? Have all of these military experts never seen any science fiction movies or read any science fiction novels?

Hat tip Tom Biggar.

SpaceX wins launch contract for unmanned lunar lander

11:24 am

Capitalism in space: Masten Space Systems has awarded SpaceX the launch contract for its unmanned lunar lander, being built to carry nine NASA science payloads to the south pole of the Moon.

Launch is tentatively scheduled for late ’22.

NASA will be an anchor customer for the mission but Masten intends to sign up others. “There is a tremendous amount of interest,” he said, including from both the public and private sector, although he didn’t mention any specific potential customers.

Mahoney said the level of customer interest soared after Masten won the CLPS award and had a firm schedule for the mission. “Once the CLPS award was made and we crossed from speculative to having a schedule, the tenor and tone of our conversations have changed dramatically.”

The limiting factor for the lander mission has not been the amount of mass available for payloads, he said, but instead positions on the lander that have views of the surface desired by payloads. “There’s a game of positioning among the various instruments so that they can get the view angles that they need and not interfere,” he said.

However, he said the company isn’t considering major changes in the lander’s design to accommodate payloads. “The design principle is the ‘pickup truck’ that can haul a bunch of different things,” he said. “We’re trying to escape the completely unique, bespoke system that does one job and one mission really well.”

I guarantee that at least one university student-built payload will end up on the lander.

FCC approves expansion of OneWeb constellation to 2,000 satellites

11:19 am

Capitalism in space: The FCC has approved the request by the satellite company OneWeb to increase the size of its satellite constellation from 720 to 2,000 satellites, at 50% of which must be launched by August ’26.

The company, now exiting bankruptcy with its purchase by a partnership of the UK government and an Indian-based communications company, appears gearing up to resume launches.

The FCC’s approval was partly because it would “increase competition for broadband services.” Under the Trump administration the goal is to encourage as many private space companies as possible, to promote innovation and the lowering of costs to the consumer. This decision continues that policy.

Five American launches in two days!

9:51 am

Capitalism in space: Though the first launches in the string of four American launches that was initially scheduled to begin two days ago and continue through the weekend was delayed because of weather and then technical issues, all these delays have done is pack those scheduled launches into a shorter time period, with the addition of a fifth launch!

If all goes as scheduled (hardly guaranteed), we will see five launches from three spaceports and four private companies in less than two days. The schedule, as of this moment:

August 29th at 2:04 am (Eastern): ULA’s Delta 4 Heavy to launch a military reconnaissance satellite from Cape Canaveral. The company’s webcast of the launch can be seen here.

August 29th at 11:05 pm (Eastern): Rocket Lab’s Electron rocket will launch a commercial radar satellite from New Zealand. The launch can be watched at the company’s live stream channel.

August 30th at 10:08 am (Eastern): SpaceX’s Falcon 9 will launch more of its Starlink satellites from Cape Canaveral. All SpaceX launches are live streamed from SpaceX’s website, though the links are not yet up.

August 30th at 7:19 pm (Eastern): SpaceX’s Falcon 9 will launch an Argentinian Earth observation satellite from Cape Canaveral. All SpaceX launches are live streamed from SpaceX’s website, though the links are not yet up.

August 30th at 10:00 pm (Eastern): Astra will attempt the first orbital test launch of its privately built rocket from Kodiak, Alaska. They will not be live streaming their launch, but will provide updates at their Twitter feed.

All times and dates list only the beginning of the launch windows, which means they might launch, but not exactly at the times listed.

Also, SpaceX is aiming to do its second Starship test hop this weekend, the first for its sixth prototype.

Democratic voters swamp CSPAN to say they are switching to Trump

9:19 am

CSPAN's new call lines, eliminating party affiliation

Is this a sign of hope? So many callers on CSPAN’s Democratic Party call line were calling to announce they were either switching to Trump or becoming Republicans after watching the two conventions these past two weeks that CSPAN changed the call lines from “Democrat” and “Republican” to “Support Biden” and “Support Trump.”

I always like to say “It’s the audience that counts.” In this case the audience appears to be making its preference loud and clear, which is to me is truly a sign of hope. Conservatives and supporters of liberty and the rule of law might cheer the speeches and presentations at the Republican convention, but it is how the unaffiliated general public reacts that matters. And at least from this one data point, it appears they are trending to the Republicans.

UPDATE: I stupidly listed the channel incorrectly as CNN in my initial post. This is now corrected.

It is the PARTY of Biden that must lose big in November

1:03 pm

Modern Fifth Avenue in New York
Today’s bankrupt New York,
a typical Democrat-run city

With the upcoming November presidential election, only two months away, the major focus continues to be on Trump and Biden. Who should win? Who is better? Do we want four more years of Trump or another four years of a Obama-type rule?

My readers will know immediately where I stand. Biden would be major disaster for the country, especially because it appears he is declining both physically and mentally and seems owned by the most radical leftist elements of his Democratic Party.

This essay, however, is a call for voters to not just vote for Trump. It is a desperate call for voters from both parties and from all ethnic, religious, and racial cohorts to vote for Republicans in every election and at every level of government. Biden is only the figurehead. It is the body of the now very corrupt, anti-American, and radical Democratic Party that must be killed, thoroughly and at all levels, including the House, the Senate, and in every state, city, and local council election.

The riots and looting and the almost willing endorsement and support given to those riots and looting by local Democratic mayors and councils and state governors demonstrates their incompetence to hold office. For the United States to survive as a nation ruled by law that also supports the freedom of its citizens, voters must reject them, unequivocally.

Canada proposes new global treaty to control mining in space

10:05 am

The globalists at the UN fight back! A Canada-led effort, endorsed by more than 140 academics, politicians, and diplomats, has proposed that the UN and international community create a new treaty to control mining in space.

Signatories to the request for the UN to intervene believe space must be regulated internationally – similarly to Antarctica or the world’s seabeds – and all countries, including non-space-faring ones, get a say in decision-making. The alternative, they warn, could be a splintered approach where companies conduct flag-of-convenience resource extraction in space under whichever country has the least onerous rules. [emphasis mine]

The Trump administration has made it clear that it wants the ability to establish U.S. law on its space operations, both in spacecraft and on its future bases on the Moon and elsewhere, an ability that the Outer Space Treaty forbids. To get around the treaty, the administration has created what it calls the Artemis Accords. The accords require that any nation that wishes to partner in the American-led Artemis program to explore and colonize the Moon must agree to support the establishment of private enterprise and ownership, with the laws of each nation applied to its own operations. To do this the Trump administration is negotiating individual bi-lateral agreements with its Artemis partners.

In essence, the U.S. is using the strategy of dividing and conquering to overcome the Outer Space Treaty’s restrictions.

Canada’s effort is designed to counter the U.S. approach, which is a strong sign that the Trump effort is working. I suspect the battle-lines are now being drawn between China and the many nations that are not operating in space (note the highlighted text), and the U.S. and those space-faring capitalistic nations that wish to partner with it, such as India and the European Space Agency. In fact, Japan and the U.S. today announced continuing negotiations leading to an agreement endorsing their partnership in Artemis, including the Artemis Accords.

Where Russia stands in this battle remains uncertain. They desperately need to partner with someone in the new effort to get to the Moon, since they no longer have the economic resources to do it themselves. The U.S. has made it clear they could join Artemis, but the Putin government opposes the Artemis Accords, preferring that the international community (meaning governments such as them) retain ownership over space resources. They have begun negotiations to partner with China, but it is unclear how much China wishes to partner with anyone.

Regardless, it would be terrible blow to freedom and private enterprise for the U.S. to agree to this Canadian-led effort. Should that approach win, it would make provide ownership and capitalism in space impossible. All power and control will devolve to the global international community, which will then dictate that nothing can happen but what it wants. For example, all the many nations incapable of doing anything in space will want a piece of the action from those nations and companies that are capable, and the result will be that no one will do anything because it simply will not be profitable. Space will simply become another failed communist state, dying before it even becomes born.

Skylab astronaut Gerry Carr passes away at 88

9:22 am

R.I.P. Gerry Carr, the commander of the last and longest Skylab mission in the 1970s, has passed away at 88.

Carr’s first and only spaceflight was as the commander of Skylab 4 (also referred to as SL-4 or “Skylab 3” as appeared on the crew’s mission patch). The third of three crewed stays of increasing duration aboard the orbital workshop, Carr and his Skylab 4 crewmates, Ed Gibson and William “Bill” Pogue, set what was then a record spending 84 days in space.

“We proved, I think, just absolutely, positively that the human being can live in weightless environment for an extended period of time,” Carr said during a NASA oral history interview in October 2000. “But medically, we gathered the data that I think gave the Russians and other people the understanding and the courage to say, ‘Okay, we can stay up for longer periods of time.'”

The obituary at the link includes Carr’s lifelong effort to explain that the crew never “mutinied,” as the press has tried to say for decades. Instead, they spent days and repeated long communications with mission control trying to get it to understand that the crew was being overworked because NASA was micro-managing their workload from the ground. They finally made mission control recognize this, after a long public conversation. Sadly, NASA had to relearn this lesson again in the 1990s during its first long missions on the Russian Mir space station (See chapters 3 and 12 in Leaving Earth).

Delta 4 Heavy launch scrubbed

11:15 pm

Tonight’s launch of ULA’s Delta 4 Heavy was scrubbed due to a variety of technical problems. They have not set a new launch time, though they say they are aiming for the early morning hours of August 28.

This was to have been the first of four American launches in the next four days. The next, a Falcon 9 launch of an Argentinian radar Earth observation satellite, was scheduled for tomorrow, August 27th, at 7:19 pm (Eastern). No word on whether it is going forward as planned, though it might be since the ULA launch has shifted after it, to August 28th.

The third, by Rocket Lab, is presently scheduled also for August 28rd at 11:05 pm (Eastern), launching out of New Zealand.

The fourth, another SpaceX launch of more Starlink satellites, had been scheduled for 10:30 am (Eastern) on August 29th. Once again, this schedule could change due to tonight’s ULA scrub.

Stay tuned. I suspect all three companies are going to aggressively work to get all four launches off as fast as possible, even if not exactly as presently scheduled.

NASA/Boeing set summer ’21 for first manned Starliner mission

4:00 pm

Capitalism in space: NASA and Boeing have tentatively scheduled the launch of the first manned Starliner mission to ISS for the summer of 2021.

Boeing Co said on Tuesday it aims to redo its unmanned Starliner crew capsule flight test to the International Space Station (ISS) in December or January, depending on when it completes software and test hardware production development.

If the test mission is successful, Boeing and NASA will fly Starliner’s first crewed mission in summer 2021, with a post-certification mission roughly scheduled for the following winter, the company added.

Everything of course depends on the success of the unmanned demo flight. If the capsule has any further problems, as it did on its first unmanned demo flight, the manned flight will likely be delayed again.

Virgin Galactic searching for profits outside of space tourism

7:52 am

Not a surprise: After almost two decades of development and no commercial suborbital tourism flights, the new management of Virgin Galactic (with Richard Branson having sold off his majority shares) is now searching for other ways to make money with its assets.

Among them, renting out the WhiteKnightTwo (WK2) launch support aircraft for government or private businesses to use for science, research, and national security applications. There’s just one problem: Legally it cannot do that.

Because WhiteKnightTwo is considered an experimental aircraft by the Federal Aviation Administration using it in this manner would be a violation of 14 CFR 91.319(a)(2), which states that “no person may operate an aircraft that has an experimental certificate – (1) For other than the purpose for which the certificate was issued; or (2) Carrying persons or property for compensation or hire.” In a filing made Tuesday The Space Company and Virgin Galactic jointly petitioned for exemption from the regulations.

It appears the new management is recognizing that the suborbital tourism market is weak (with the coming of orbital tourism), and needs to shift gears, any way it can.

A nuclear battery that never needs charging?

10:14 am

A California company, NDB (which stands for nuclear diamond battery), is developing a nuclear battery using waste products from nuclear power plants that will never need charging and will be able to replace almost any ordinary battery, from those used in computers and smart phones to AA and AAA batteries.

The heart of each cell is a small piece of recycled nuclear waste. NDB uses graphite nuclear reactor parts that have absorbed radiation from nuclear fuel rods and have themselves become radioactive. Untreated, it’s high-grade nuclear waste: dangerous, difficult and expensive to store, with a very long half-life.

This graphite is rich in the carbon-14 radioisotope, which undergoes beta decay into nitrogen, releasing an anti-neutrino and a beta decay electron in the process. NDB takes this graphite, purifies it and uses it to create tiny carbon-14 diamonds. The diamond structure acts as a semiconductor and heat sink, collecting the charge and transporting it out. Completely encasing the radioactive carbon-14 diamond is a layer of cheap, non-radioactive, lab-created carbon-12 diamond, which contains the energetic particles, prevents radiation leaks and acts as a super-hard protective and tamper-proof layer.

To create a battery cell, several layers of this nano-diamond material are stacked up and stored with a tiny integrated circuit board and a small supercapacitor to collect, store and instantly distribute the charge. NDB says it’ll conform to any shape or standard, including AA, AAA, 18650, 2170 or all manner of custom sizes.

The company says it has already built a proof-of-concept, and will begin building commercial prototypes as soon as it can reopen (they were shuttered by the Wuhan flu panic).

More at the link. Also see the video below the fold. To say this technology would be game-changing is an understatement of epic proportions. At the same time, a lot of difficult work will be required to make it practical and affordable. Don’t expect this to be available in stores for at least a few years.

Four American launches in the four days

9:39 am

UPDATE: Rocket Lab’s launch has been delayed to 11:05 pm (Eastern) August 28 due of weather.

Beginning tomorrow, the next four days will be very busy for the American space rocket industry, with three companies attempting to complete four different launches.

First comes Rocket Lab, which will attempt its first launch of its Electron rocket since its first operational launch failure on July 4. Launch is scheduled for 11:05 pm (Eastern) on August 26th.

Next ULA is scheduled to use its most powerful rocket, the Delta 4 Heavy, to put a National Reconnaissance Office surveillance satellite into orbit. Launch is set for 2:12 am (Eastern) on August 27th. This very expensive rocket (which costs three to four times that of a Falcon Heavy) has only four launches left before being permanently retired.

Then SpaceX will attempt two launches in quick succession. The first will launch at 7:19 pm (Eastern) on August 27th, putting up an Argentinian Earth observation radar satellite. On this launch the first stage is a new one, and will attempt the first landing at Cape Canaveral since March 2020.

SpaceX will then follow with its third Starlink launch this month and twelfth overall, scheduled for 10:30 am (Eastern) on August 29th out of its facility at Cape Canaveral, assuming the other launches at Kennedy go as planned.

Moreover, the startup smallsat rocket company Astra is also aiming to attempt its first test launch before the end of August. The date is not yet set.

Busy times for sure, but note that this is only the beginning. I expect by the end of the 2020s the launch schedule will get increasingly packed. Soon having three three launches per week will seem routine.

Russia to continue bilateral space negotiations with U.S.

9:28 am

According to one Russian foreign policy official, the Putin government will continue bilateral space negotiations with United States in connection with both its Artemis Accords (designed to encourage private ownership in space) and the military doctrines in space recently set forth by the U.S. Space Force.

The official also made note of a Russian-Chinese agreement related to the use of space, which seems to counter what the Trump administration is pushing with the Artemis Accords. However, the fact that these bilateral agreements and negotiations now exist actually gets the U.S. what it wants, foreign treaties that set out goals and rules that bypass the restrictions of the Outer Space Treaty. Those restrictions make private ownership in space legally questionable. That Russia is willing to continue negotiations with the U.S. means that it might agree eventually to some framework that allows private property in space, in order to remain a partner in the Trump administrations Artemis lunar project.

Blue Origin-led partnership delivers lunar lander mockup to NASA

9:14 am

Capitalism in space: The Blue Origin-led partnership, which calls itself “the National Team,” has delivered to the Johnson Space Center a full scale mock-up of the manned lunar lander it is building for NASA.

The full-sized, but low-fidelity, mockup includes both the descent element, developed by Blue Origin, and ascent element, built by Lockheed Martin, and stands more than 12 meters high.

The companies developed the mockup to allow NASA astronauts and engineers to study the layout of the vehicle, including positioning of various components, and get feedback while the lander is still in an early stage of development.

While providing this mock-up to NASA for design review makes sense, I must say that I yawned when I saw the string of overly excited new reports about it from almost every mainstream news outlet. It appears that though Jeff Bezos and Blue Origin have become very skilled at delivering nothing but mock-ups and promises over the past few years, both have also become very skilled at getting the press pumped up with each new mock-up and promise.

More and more does Bezos and Blue Origin remind me of Richard Branson and Virgin Galactic, making promises and holding spectacular fake press events, but actually achieving little. I could be wrong, but I can’t get that similarity out of my head. Blue Origin was founded in 2000, before SpaceX, and after more than twenty years it has yet to fly anything commercially. Work on its New Shepard reusable suborbital rocket has apparently stalled, without ever flying humans. Its main rocket engine, the BE-4, is taking years to develop, with only test versions built, none flightworthy. And New Glenn, its orbital rocket, remains a fantasy.

I truly hope my cynicism here is unfounded. I want Blue Origin to succeed. I just wish they’d finally do something.

UK spaceport in north Scotland approved

8:38 am

Capitalism in space: A commercial spaceport in Sutherland, Scotland, has received full approval from the local planning commission.

With planning permission now secured, construction is on course to begin before the end of the year, and HIE is hopeful that the site could be operational and supporting its first launch as early as 2022.

Their prime customer, a UK company dubbed Orbex Space, had said two years ago it would do its first launch by 2021, so this announcement also reveals a year delay in that first launch.

Lockheed Martin, teamed with Rocket Lab, has also said it will launch from this site.

Musk: 100+ reuses of Falcon 9 1st stages possible

8:25 am

Capitalism in space: According to Elon Musk:, based on what SpaceX has learned so far in reusing the 1st stages of its Falcon 9 rocket, it is entirely possible that the present design could result a hundred or more reuses.

Now, with all that experience in hand and a Falcon 9 Block 5 booster already 60% of the way to the ten-flight reuse milestone, Musk says that “100+ flights are possible” and that “there isn’t an obvious limit.” While “some parts will need to be replaced or upgraded” to achieve dozens or hundreds of booster reuses, Musk says that SpaceX “almost never need[s] to replace a whole [Merlin 1D] engine.

Given that a Falcon 9 booster’s nine M1D engines are likely the most difficult part of each rocket to quickly and safely reuse, it’s extremely easy to believe that individual boosters can launch dozens – if not hundreds – of times with just a small amount of regular maintenance and repairs. In that sense, SpaceX has effectively achieved Musk’s long-lived dream of building a rocket that is (more or less, at least) approaching the reusability of aircraft.

The next step in this effort will be to shorten the turnaround times. At the moment the best time between any booster’s reflight has been just under two months. SpaceX has said they want to be able to refly boosters in just days.

Conservative firebrand Loomer easily wins Republican primary

9:25 pm

A good sign: Conservative firebrand and outsider Laura Loomer easily won her Republican primary today in Florida, beating five opponents by a large margin.

Loomer gained prominence on social media over the past few years for a number of stunts, including handcuffing herself to Twitter’s headquarters to protest her suspension from the platform and hopping the fence at Speaker of the House Nancy Pelosi’s house to protest immigration. In addition to her suspension from Twitter, Loomer has also been suspended from GoFundMe, Facebook, Uber, and Lyft.

After being suspended from multiple platforms, Loomer’s campaign message was that of free speech, “making America safe again,” and the Second Amendment. With the help of large donors, Loomer raised more than $1 million while campaigning.

She will now face the Democratic incumbent, Lois Frankel, in the November election.

Rocket Lab planning private Venus mission

8:33 am

Capitalism in space: According to its founder and CEO Peter Beck, the smallsat rocket company Rocket Lab is now planning a private Venus mission to be launched in 2023.

The 2023 mission will employ Rocket Lab’s two-stage Electron booster and Photon satellite bus. The 57-foot-tall (17 meters) Electron is a viable option for interplanetary missions now, thanks to recent advances in battery technology that boost the performance of the rocket’s Rutherford engines. With that improvement, Electron is now capable of lofting up to 660 lbs. (300 kilograms) of payload to low-Earth orbit instead of 500 lbs. (225 kg), Rocket Lab representatives have said.

“It opens the window for Venus, and it opens the window for recovery,” Beck said. (The company is working to recover and reuse the Electron’s first stage. Returning boosters will make guided re-entries to Earth’s atmosphere, which will require more fuel, which in turn will require more powerful engines to get the added weight off the ground.)

Photon, which has yet to make its spaceflight debut, won’t descend into Venus’ sulfurous skies on the coming mission. The current plan calls for the spacecraft to deploy one or more smaller probes into the planet’s atmosphere, Beck wrote in a Twitter post on Aug. 4.

There is a certain irony here, if Beck launches a private interplanetary science mission ahead of Elon Musk. Musk created the rocket company SpaceX expressly because he wanted to do a private science mission to Mars and needed an affordable rocket to do it. Since then he has been so focused on making that rocket company succeed he has not devoted any effort to that initial science mission concept. Beck, who came much later, now appears set to beat Musk to this first milestone.
