Rocket Lab to build new bigger rocket

9:05 am

Capitalism in space: As part of its announcement yesterday that Rocket Lab is going to become a publicly traded stock, the company also announced it is going to develop a new larger rocket, dubbed Neutron, to supplement its smaller Electron rocket.

The second link provides some additional details about Neutron.

Today, Monday, 1 March, the company revealed its “Neutron” rocket, a medium-class launch vehicle that can lift up to 8,000 kilograms (eight tonnes) into orbit, comparable to Russia’s Soyuz rocket. The two-stage vehicle will be 40 meters (131 feet) tall, more than double the company’s existing Electron rocket, which measures 18 meters (60 feet) tall and has so far flown 97 satellites across 18 launches.

They will design it to be human-rated from the start, and will also have the first stage land vertically using its engines so it can be reused. According to video from the company, they are aiming for a ’24 launch date.

Update on ISS leaks: Several to be drilled & sealed over next 5 days

8:44 am

According to Russia’s state news service, astronauts on ISS have located several leaks in the 20-year-old Zvezda module of ISS, and will spend the next five days fixing them.

This report clarifies a previous report that left more questions than it answered. It appears that there are several leaks that were found using a microscope sent to the station and temporarily sealed. Now the goal in the next five days will be to permanently seal them.

[A] hole will be drilled at one of the fracture’s ends, which will be filled with cold welding and sealed with a fluoroplastic film on top. The same procedure will be done with other holes. After that, the surface will be sanded and wiped with alcohol wipes and covered with a sealant. Overall, the cosmonauts will put three layers of the sealant.

The repair method suggests that they are all cracks. To stop a crack from growing you drill out the end.

That they are all cracks further suggests that these are all stress fractures. Thus, no matter how permanent these particular repairs are, they cannot solve the greater problem of the aging module itself. We should expect more cracks to appear in the future unless something more drastic is done.

Booster landing failure on Feb 15 Falcon 9 launch began with engine issue during lift-off

8:37 pm

SpaceX revealed today that the failure on February 15th of the 1st stage of the Falcon 9 rocket to land successfully first appeared during liftoff.

During a NASA press conference March 1 about the upcoming Crew-2 commercial crew flight, Benji Reed, senior director for human spaceflight programs at SpaceX, said that while the booster used on that Feb. 15 launch was making its sixth flight, some components on it were “life leaders” that had flown more often than any other in the Falcon 9 fleet. That included “boots,” or covers around parts of the Merlin engines in the first stage. “This was the highest count number of flights that this particular boot design had seen,” he said.

However, one of those boots had a “little bit of a hole” that allowed hot gas to get into parts of the engine during flight, he said. “A little bit of hot gas got to where it’s not supposed to be, and it caused that engine to shut down,” he said. Reed didn’t mention at what point in the launch the engine shut down, but he suggested it took place during ascent.

…The shutdown of the engine, though, kept the first stage from landing. “When that booster came to return home, because of the problem with that particular engine, we didn’t have enough thrust to get back to where we needed to be, and didn’t land where we wanted to be,” he said.

These facts help explain why SpaceX paused all its subsequent flights. An issue during liftoff is more serious than one that occurs during the return to Earth, as it suggests a problem that could impact future launches and the ability of the rocket to deliver its payload, its primary task.

Stockholm 1913

6:01 pm

An evening pause: The footage is gently colorized but with little else changed. Like previous such pauses showing film footage from the past, it gives us a glimpse into a different world that appears more dignified and civilized.

Hat tip Björn “Local Fluff” Larsson, who notes, “All men wear suits and hats. All ladies are dressed up. All buildings are beautiful. Then socialism happened.”

State legislatures proposing repeals of 2020 election revisions that made fraud easy

1:46 pm

I’ll believe it when I see it: The state legislatures of Arizona, Georgia, and Pennsylvania — all strongly controlled by Republicans — are now considering numerous proposals to repeal the many improvised revisions to state election laws that made fraud easy and contributed to the widespread belief of many that the 2020 presidential election was stolen by the Democrats.

Significant legislative attempts are underway in multiple U.S. states, including key battleground states, to roll back major changes in voting rules and regulations to various pre-2020 status quo antes. The efforts come after an historically chaotic election process that has left millions of Americans doubtful of election fairness, security, transparency and accountability.

Changes to election rules — some of them enacted prior to 2020 and others put in place in response to the COVID-19 pandemic last year — have included expansive mail-in voting, expanded early voting, relaxation of verification rules, and extensions to ballot receipt deadlines.

Those rules likely contributed to a record 158,000,000-plus votes cast in the 2020 election. But the relaxation of various voting requirements has also led to significant distrust in the election system: Nearly 40% of voters believe that U.S. elections are beset by fraud, while a similar number claim that such concerns haven’t been properly vetted by public authorities.

As far as I am concerned, until these changes are actually imposed and enforced, stories like this are nothing more than another example of Republican Party failure theater: lots of big talk that means nothing.

And if you sense a bit of contempt for these Republicans, you are not mistaken. I have watched them stand by impotently for decades as the the principles of freedom and individual rights that this country stands for were trampled upon and nullified, step-by-step by the corrupt and power-hungry Democratic Party. Why should I hold any respect for them?

Today’s blacklisted American: Bi-racial make-up artist fired for singing a rap song as requested by black actor

1:00 pm

They’re coming for you next: An experienced bi-racial make-up artist was immediately fired from a new Amazon television project for simply singing a rap song — with the black actress who had suggested it and had joined in — that happened to contain the evil N-word that must never be spoken.

Earlier this month, Page Six reported that the artist in question was canned from the “Untitled Tracy Oliver Project” — the new show from the “Girls Trip” creator dubbed the “Black Sex and the City” — for allegedly saying the N-word repeatedly in front of one of the show’s lead actresses, while singing along with a rap song. (We know both the name of the actress and the makeup artist, but we aren’t going to print them due to the sensitivity of the situation. The makeup artist is a veteran of many major TV shows and movies.)

Now Page Six is told that her peers are outraged that the artist was fired for using the word — especially, we’re told, because the makeup artist is biracial.

Her union has done nothing to help this artist, though it graciously decided not to pursue charges against her. How nice of them.

I also do not have much respect for the so-called outrage of the artist’s “peers.” They only care because of her race. If the artist had been white and done the same, inspired by the black artist, I don’t believe they’d care at all. In the modern leftist culture that these people are seeped in the only thing that matters is race. If you have the right minority race, you can do no wrong. If you don’t, your rights are forfeit, and instead you must bow like a slave to that culture.

This is also par for the course for Amazon, which is enthusiastically embracing blackballing for petty and political reasons, almost always against conservatives or anyone who criticizes their leftist racist identity politics.

Biden fires Boeing on SLS; gives job to Acme

12:41 pm

In an interesting announcement today, the Biden administration fired Boeing as the prime contractor for SLS and gave the job to a well-known southwest company dubbed Acme.

Anticipating critical comment, White House spokesmen pointed out that Acme had a long history of use of solid-fuel rockets for crewed applications, “without loss of human life or serious injury” despite some less-than-fatal mishaps.

…The spokesperson also added, “It should be noted that Acme’s products have never killed anybody. Unfortunately the same can’t be said for Boeing.”

Before you comment, make sure you read the article at the link closely, and also click on the two links in the article to get some detailed background on Acme, from some original sources.

A deep south Martian dune with bright patches

Dune with bright patches
Click for full image.

Cool image time! Last week the MRO science team posted a new captioned image entitled “Bright and Dark Dunes” featuring a particularly large single dune in the floor of a 25-mile-wide unnamed crater located at about 68 degrees south latitude. The photo to the right, rotated, cropped, reduced, and color enhanced to post here, shows that dune. According to the caption, written by Colin Dundas of the U.S. Geological Survey’s Astrogeology Science Center in Arizona,

This image shows a large sand dune with bright patches. Martian dunes near the poles often have bright patches in the spring, when seasonal frost is lingering. However, this image is from late summer, when frost is long gone. What is going on here?

A close-up look with [MRO’s high resolution camera] provides some clues. The bright patches are made up of large ridges that look like wind-blown bedforms. Additionally, the bright patches are yellowish in the infrared-red-blue image. In enhanced color, most sand on Mars is blue but dust is yellow. This suggests that the bright bedforms are either built from, or covered by, dust or material with a different composition.

Thus, the bright patches reveal either aspect of the dune’s underlying structure, either inherent in the bedrock itself, or the texture of its surface that allows it to hold more dust. As Dundas adds, “I think more study would be needed to determine the answer in this particular case.”

There are other aspects of this dune that can be seen by a look at the wider view afforded by MRO’s context camera below.

Looking into one of Jupiter’s smaller cyclones

A northern cyclone on Jupiter
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken by the Juno probe orbiting Jupiter and enhanced first by citizen scientist Kenneth Gill and then further enhanced by citizen scientist Navaneeth Krishnan.

Sadly all the link tells us about this storm is that it is in the northern hemisphere. Based upon the colors, my guess is that it located at the high latitude where Jupiter’s bands transition to the chaotic region of storms at the poles, as seen in this earlier wide image of the gas giant’s south pole.

No scale is provided, but an earlier image of other northern hemisphere storms suggests this storm would probably cover the state of Arizona.

SpaceX: No 1st stage footage on tonight’s Starlink launch

9:22 am

During last night’s short broadcast leading to the abort at T-1:24 seconds of a launch of another 60 Starlink satellites, the company announced that it would not show the video feed from the reused first stage booster as it returned to Earth.

[A] SpaceX engineer revealed that the company would not be broadcasting live feeds from Falcon 9 B1049’s onboard cameras during the launch. The ambiguity of the comment made it impossible to determine if SpaceX was simply choosing to not show those views or if something was wrong with the camera downlink system, while the same engineer-turned-host did go on to state that “all systems are green” moments later.

No explanation for the sudden change – possibly the first webcast in years without live views from booster cameras – was given. Starlink-17 serves as a return-to-flight mission for SpaceX after Starlink-19’s failed landing, during which the rocket’s onboard cameras streamed what appeared to be clearly unusual and possibly off-nominal behavior early on in the landing process.

The article at the link then speculates that maybe SpaceX was worried about that booster’s ability to land (it will be flying its eighth time, same as the booster that failed on the earlier flight).

I am very skeptical of that theory, especially because SpaceX has never shown a reluctance to show the public its failures. Instead, I think SpaceX has decided to do an engineering test of that booster during its return, and for propriety reasons wants to keep this from public eyes. If so, the test itself might also mean they are willing to lose this booster during that test.

During the early days of their program to reuse boosters, they sometimes had the returning 1st stage do some very stressful maneuvers, producing very spectacular light shows when launched from Vandenberg on the California coast. It could be they want to test this older booster on its eighth flight in a similar manner, in order to reassess their engineering and thus make it possible to upgrade and extend the re-usability of later boosters.

Rocket Lab about to go public

9:07 am

Capitalism in space: According to news reports today, the smallsat rocket company Rocket Lab is about to sign a deal that will make it a publicly traded stock in a merger with a venture capital company.

The Wall Street Journal reported today talks between the company and Vector Acquisitions Corp were nearing completion and could be finalised with 24 hours, and was expected to see Rocket Lab raise another $650 million in cash from other private investors.

Vector is a special-purpose acquisition company, a vehicle that recruits investors and lists before pursuing a business to buy. Vector, backed by tech private equity firm Vector Capital, raised $400m on launch in September.

Rocket Lab is one of a cluster of spaceflight operators jostling for global market share in the smaller-launch market, where the focus is on achieving reliable delivery of small cargoes to lower earth orbits. Any listing would catapult Rocket Lab – whose Mahia spaceport has delivered nearly 100 satellites into orbit – into the top rank of New Zealand companies, and represents a huge blow for the local NZX. With a valuation of $5.7b, it would have ranked as one the 10 largest companies on the national exchange.

According to Rocket Lab, it is not a New Zealand company but based in the U.S., despite the bulk of its operations being in New Zealand.

I will not be surprised it Rocket Lab’s stock price quickly rises once available for purchase. Unlike Virgin Galactic, this is a real company with a real product producing real profits. It is also very well placed to garner a healthy share in the emerging launch market of smallsats that is now arriving on the scene. The company is about to initiate launches from its second launchpad at Wallops Island in the U.S., which will also allow it to finally accelerate its launch pace to the promised twice a month pace it has been promising for the last two years.

India & Russia successfully launch satellites

11:04 pm

Both India and Russia today successfully launched satellites into orbit.

For India it was their first launch in 2021. Their PSLV rocket put into orbit a Brazillian satellite for studying Earth resources. The launch also included 18 other cubesats.

Russia in turn used its Soyuz-2 rocket to launch a new generation weather satellite for studying that country’s remote Arctic regions.

SpaceX had also planned another Starlink launch but aborted the countdown with just over a minute to go. They plan to try again tomorrow.

The 2021 launch race:

5 SpaceX
4 China
3 Russia
1 Rocket Lab
1 Virgin Orbit
1 Northrop Grumman
1 India

The U.S. still leads China 8 to 4 in the national rankings.
