Rocket Lab launches seven satellites; recovers first stage from ocean

6:46 pm

Rocket Lab today successfully used its Electron rocket to place seven smallsats into orbit, lifting off from New Zealand.

The first stage used parachutes to softly splash down in the ocean, where it was recovered for refurbishment and relaunch. As this stage is the first in which this full reuse will be attempted, the ability to refurbish the stage after its salt water swim remains the critical factor. We will not know its state until a complete inspection plus static fire engine tests are completed.

The leaders in the 2023 launch race:

47 SpaceX
26 China
9 Russia
6 Rocket Lab
5 India

American private enterprise now leads China in successful launches 54 to 26, and the entire world combined 54 to 45, while SpaceX alone still leads the rest of the world (excluding other American companies) 47 to 45.

Flat-topped Martian mesa

3:58 pm

Flat-topped mesa on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, and reduced to post here, was taken on April 18, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows only one of many flat-topped mesas in a chaos terrain region dubbed Oxia Chaos.

The mesa top is about 540 feet above the floor of the canyon to the north, which in turn is about 840 feet below the flat terrain north of it. That flat terrain to the north is not part of the chaos terrain, however, but the northern rim of the plateau that surrounds the chaos. Moreover, this particular piece of rim is separating from the plateau, as shown near the top of this January 16, 2008 context camera image from MRO. At some point in the future it will break off and fall into that canyon and on top of this mesa.

California Democrats retreat on their effort to defend child slavers

12:34 pm

The Democratic Party: eagerly supporting pedophilia
The Democratic Party: caught in the act of eagerly
supporting pedophiles

Pigs fly! After initially killing a bill on July 12, 2023 that would have increased the penalties on child sex traffickers, the Democrats who completely control the California Assembly’s Public Safety Committee reversed course one day later and voted to advance the bill.

With a final vote of 6-0, including two abstentions from progressive Democrats, the bill now moves to the Appropriations Committee, after which, if it is approved, can move the bill to be voted upon by the entire State Assembly. If passed, SB 14 will make trafficking of minors a serious felony that would qualify under California’s three strikes law, which keeps dangerous, serial criminals off the streets, and make individuals convicted of the crime ineligible for early release. [emphasis mine]

I highlight the two abstentions by Democrats. Even after a nationwide uproar over their willingness to block harsh penalties on those who traffic young children for sexual slavery, these two Democrats, including Assembly Majority Leader Isaac Bryan (D-Los Angeles), still could not bring themselves to vote for the bill.

Nonetheless, the reversal by the rest of the Democrats on the committee marks a major event. » Read more

Chandrayaan-3 completes second orbital maneuver

9:32 am

Chandrayaan-3's mission profile

According to India’s space agency ISRO, its lunar lander/rover Chandrayaan-3 today completed second orbital maneuver, raising the spacecraft’s orbit around the Earth from 41,762 by 173 kilometers to 41,603 x 226 kilometers.

The graphic to the right shows the entire mission profile of Chandayaan-3. It still has three more orbital adjustments to make in Earth orbit before it does its trans-lunar-injection burn to send it to the Moon. Once it arrives in lunar orbit it will then have to make six orbital adjustments to lower its orbit before making the descent to the surface.

The lunar landing itself is presently scheduled for August 23, 2023.

An apparent rocket section washes up on Australian coast

9:19 am

What appears to be a section of India’s PSLV rocket washed up on the western Australian coast yesterday, though at the moment the identity of the wreckage as not been confirmed.

Dr Alice Gorman, an expert in the field of space archaeology, said she believes the object is a fuel cylinder that came from the the third stage of India’s polar satellite launch vehicle rocket (PSLV), as many have suggested on social media.

The article includes a picture of that stage in orbit during a 2017 launch, and the similarity is obvious. If true, its specific launch at present remains unknown, though it appears it could have been floating in the ocean for years, a fact that is surprising in itself.

SpaceX launches using its second Falcon 9 first stage on its sixteenth flight

9:14 pm

SpaceX tonight successfully launched 54 Starlink satellites into orbit, lifting off from Cape Canaveral.

The Falcon 9 rocket used a first stage flying on its sixteenth flight, landing successfully on a drone ship in the Atlantic. That is the second 1st stage in SpaceX’s fleet to complete that many flights. Both first stages completed their sixteen flights in only three years, which means that those two first stages have actually flown more times than the entire United States rocket industry did annually from 2000 to 2019. I don’t have a full count, but I suspect both stages have launched in those three years more satellites then the totals for almost all other nations, excepting possibly Russia and the U.S. Both probably allowed SpaceX to amortize the cost of those launches considerably, possibly as much as 90%.

Just remember: Rocket industry experts were insisting even as late as 2016 that it was impractical to make rocket stages reusable, that to make a profit “a partially reusable rocket would need to launch 35-40 times per year to maintain a sizable production facility while introducing reused hardware into the manifest.” Based on that calculation, these experts determined with utmost certainty that a partly reusable rocket — like the Falcon 9 — could never make a profit.

Elon Musk must have agreed, and decided he needed an extra profit center for the Falcon 9. Starlink has provided that profit center. It not only needs that many launches, and pays for them, its profit stream from its internet customers is already adding to SpaceX’s bottom line.

Regardless, Musk has proved these “experts” utterly wrong. I always thought they were talking through their hat, but had no way to prove it. Thank you Mr. Musk for proving the point.

Note too that the two fairing halves on this flight were also reused, completing their ninth and tenth flights respectively.

The leaders in the 2023 launch race:

47 SpaceX
26 China
9 Russia
5 Rocket Lab
5 India

American private enterprise now leads China in successful launches 53 to 26, and the entire world combined 53 to 45, while SpaceX alone now leads the rest of the world (excluding other American companies) 47 to 45.

And it is doing this with that impractical, unprofitable, and impossible reusable Falcon 9 rocket. Heh.

House committee imposes major cuts to Justice, FBI, Commerce

11:15 am

As had been suggested by its decision to not impose any cuts (or increases) to the NASA budget, the House appropriation subcommittee in charge of Commerce, Justice, Science-related agencies imposed all of the 28.8% cuts required by the House leadership on the Department of Justice, the FBI, and the Commerce department.

Overall, the bill appropriates $58.4 billion for programs under the jurisdiction of the committee, a $23.8 billion cut compared to the current fiscal year. It eliminates 14 “diversity, equity and inclusion” programs in the covered agencies, cuts spending on “wasteful” climate change programs, and saves more than $50 million by ending the Biden administration’s plan to replace auto fleets at the Department of Commerce and Department of Justice with electric vehicles.

According to the GOP summary, the Commerce Department would see a $1.4 billion cut in discretionary funding, and the Department of Justice would see a $2 billion cut. Federal science agencies together would face a $1.1 billion cut under the bill.

The FBI’s budget is to be cut $1 billion, or 9% (an actual cut, not a reduction in the increase in spending), with $400 million of that coming from salaries and expenses. It also forbids the agency from spending a dime on its planned dream of a new posh and palatial headquarters in the DC suburbs, twice the size of the Pentagon and costing more than $3 billion.

This is exactly what Republicans should have been doing for decades, and were too cowardly to attempt. If an agency of unelected employees in the executive branch abuses its power and causes harm to innocent citizens, something the FBI and the Justice Department have been eagerly doing since Trump became president, then it is the responsibilty and obligation of Congress to use its power of the purse to cut those agencies’ funding.

Even now, however, no one should be confident these cuts will end up in the final bill. This is only the recommendations of one subcommittee. There are still many Republican cowards in the full House, and even more in the full Senate, who will gladly team up with the Democrats (who are all in favor of the abuse of power and the harm to innocent citizens) to reinstate the cuts.

Nonetheless, this is a start. It indicates that we might finally have turned a real political corner towards reform.

Chase Hiller – Skateboarding down a mountain in Columbia

6:01 pm

An evening pause: For the weekend, some recreational activity. There are two or three cuts, but in general he makes the whole run non-stop. If you want to get your palms sweating play some of this at 2x normal speed. The location is in San Felix, Columbia.

Hat tip Tom Wilson.

Farewell Skipper

4:01 pm

Skipper and Emma in 2016
Emma and Skipper

Today there will be no political column, because to be honest, there are things in life more important. After fortunately a very short illness, we were forced to put to sleep our dog Skipper, as shown to the right in 2016, with then-a-very-young Emma behind him, plotting evil. Emma passed away prematurely a year and a half ago at only a decade of life. At his passing Skipper was about seventeen years old.

We think Skipper was a mix of Schipperke and Chihuahua. Both breeds are known for their uppity nature. Skipper had that in spades. For almost his entire life he was active, friendly, and independent. He would only do what he wanted to do, which sometimes was great and sometimes not so great. For example, we have a dog door and a very large fenced back yard. He liked to go outside and bark at the coyotes, sometimes facing off against them with only our six-foot-high cattle fence in-between. The coyotes were unphased, but to Skipper, he had declared that our yard was his territory. Stay out!

Until the last year he also like to bark when visitors arrived, but his only desire in doing so was to get petted. If they stopped, he’d bark again. Pet me!

His outside barking was not always perfect however. If we didn’t close the dog door, he would always go outside at about 4 am every night, plant himself five feet from our bedroom window, and bark relentlessly. I’m the boss! One of us would have to get up and bring him in.

Yes, he wasn’t perfect, but Diane had rescued him in 2012 when he had been for several years shifted from one foster home to another. His original owner had died, and the foster organization had been unable to find him a permanent home. We gave one to him, one he liked quite a lot, and for this the heavens smiled.

I’d go on, but I need to dig a grave in the backyard, next to the graves of Emma, Fitz, and Wolfie.
