Endeavour Dragon capsule carrying four astronauts safely splashes down

8:53 am

SpaceX’s Endeavour Dragon capsule safely splashed down shorty after midnight last night in the Atlantic off the coast of Florida, completing a six month mission for two Americans, one Russian, and one astronaut from the United Arab Emirates (UAE).

The UAE astronaut, Sultan Al Neyadi, flew as a paying passenger, obtaining his flight through the private space station company Axiom, which in turn purchased the ferrying services to and from ISS from SpaceX. The Russian flew as part of the barter deal that NASA presently has with Russia, with each flying astronauts on the other nation’s capsules at no cost in order to make sure everyone knows how to use them in case of emergency.

Several additional details: First, in the post-splashdown press conference SpaceX officials revealed they are presently building a fifth manned Dragon capsule to add to its fleet, and are also aiming to fly each as much as fifteen times. This suggests they are anticipating a lot of business hauling both NASA and commercial passengers into space.

Meanwhile, the Russian-launched crew on ISS that launched last September and includes American Frank Rubio is targeting a return-to-Earth on September 27, 2023. If so, they will have completed a 371 day flight, or almost thirteen months. This I think is the second longest human flight so far in space, exceeded only by Valeri Polykov’s fourteen-and-half month mission in the 1990s.

Engineers had Vikram do short flight hop prior to shutting down

8:36 am

Indian engineers revealed today that prior to putting the Vikram lander to sleep for the long lunar night, they had the lander use its rocket engines to do a short up and down flight. From the first link:

“On command it (Vikram lander) fired the engines, elevated itself by about 40 cm as expected and landed safely at a distance of 30 to 40 cm away,” ISRO said in an update on ‘X’.

Before doing the hop engineers stored Vikram’s instruments and rover ramp, then redeployed them afterward to gather a tiny bit of new data before putting everything into hibernation.

The hop test proved that Vikram’s engines could be restarted even after being on the Moon for almost two weeks, and thus could potentially be used on a future sample return mission. It also suggested a future mission could choose to change its landing site periodically by use of its landing engines.

ESA successfully test fires upper stage engines of new Ariane-6 rocket

12:02 pm

Despite delays in test firing the first stage engines on ESA’s new Ariane-6 rocket, it has successfully tested fired the rocket’s upper stage engines in Germany.

The test of the full upper stage – including the new Vinci engine and a smaller Auxiliary Power Unit (APU) – took place on a purpose-built test bench at German Aerospace Center DLR’s engine test centre in Lampoldshausen, Germany.

Vinci, the upper stage engine of Ariane 6 fed by liquid hydrogen and oxygen, can be stopped and restarted multiple times – to place satellites into different orbits and then de-orbit the upper stage, so it is not left behind as hazardous debris in space. The APU makes it possible for Vinci to restart in space, by maintaining adequate pressure in the fuel tanks and preventing bubbles in the fuel lines. The APU uses small amounts of liquid hydrogen and oxygen from the main tanks – replacing a system which relied on large quantities of tanked helium.

A last hot-fire test is scheduled before final qualification of the Ariane 6 upper stage, with the aim of testing its operation for different types of missions, as well as in degraded conditions.

Meanwhile, the next attempt to do the same with the first stage in French Guiana is scheduled to take place on September 5th.

SpaceX launches 13 satellites for the Space Force

10:32 am

SpaceX early this morning successfully completed its second launch for the Space Force, lifting off from Vandenberg Space Force Base in California and placing another thirteen satellites of its Tranche-0 constellation into orbit.

The first stage completed its thirteenth mission, successfully landing back at Vandenberg.

This flight was SpaceX’s 61st in 2023, which matches the record it set last year, doing it in only eight months. With four months still left to go in the year the chances of SpaceX meeting its goal of 100 launches in the year still remains a possibility.

Furthermore, this was the 70th successful launch for the United States this year, which matches the record that the nation had set in 1966, and had been the record for the country until last year, when American companies (with help of one government launch) completed 85 launches. It seems last year’s record will be smashed without much problem.

The leaders in the 2023 launch race:

61 SpaceX
38 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise now leads China in successful launches 70 to 38. It also leads the entire world combined, 70 to 62, while SpaceX by itself now trails the rest of the world (excluding American companies) by only 61 to 62, with another Starlink launch is now scheduled for tomorrow.

India successfully launches its first solar observation satellite

11:44 pm

India’s space agency ISRO tonight (September 2, 2023 in India) successfully used its PSLV rocket with six strap-on boosters to place in orbit its first solar observation satellite, Aditya-L1, lifting off from its coastal Sriharikota spaceport.

The spacecraft will eventually maneuver itself to the L1 point about one million miles closer to the Sun, where it will make continuous observations of the star’s visible hemisphere, using seven different instruments. Its observations will supplement those of the SOHO solar observatory (also located at the L1 point), which was launched in 1995 and is long overdue for replacement, or at least some redundancy.

For India, this was the seventh launch in 2023, which ties its previous annual launch high achieved in both 2016 and 2018. The country however has three more launches tentatively scheduled for this year, though none has as yet a specific launch date.

The leaders in the 2023 launch race:

60 SpaceX
38 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise still leads China in successful launches 69 to 38. It also leads the entire world combined, 69 to 62, while SpaceX by itself now trails the rest of the world (excluding American companies) 60 to 62. SpaceX however has launches scheduled for September 2nd and 3rd, so these numbers are likely to change.

Real pushback: School district immediately cancels ban on prayer when threatened with lawsuit

1:27 pm

The First Amendment, becoming accepted once again
The First Amendment, becoming accepted once again

Bring a gun to a knife fight: When the officials at West Shore School District in Pennsylvania sent out a letter to the presidents of the various booster clubs at its schools ordering them to “halt prayers at future banquets, and at any other school-sponsored activity” and claiming falsely that “student-initiated prayers at school events are illegal,” two non-profit free speech legal firms, First Liberty and the Independence Law Center teamed up to immediately send a letter to the district challenging that order:

First Liberty and our friends at the Independence Law Center quickly sent a letter to district officials asking them to immediately rescind that threatening letter. Our legal team offered to help draft a new letter and policies to ensure the district would not illegally discriminate against students and staff.

We explained in our letter that the First Amendment prohibits a school district from acting in a hostile manner toward religious belief.

To my readers this story is familiar. What has normally happened next in the past few years — since censorship and blacklisting has become all the rage by those in power — is that the government officials either ignore the letter or publicly defy it. Sometimes they double down and actually fire someone for exercising their First Amendment rights. What follows next is of course a lawsuit, which almost routinely ends in a crushing defeat for the school that costs it significantly in damages.

This story however ended quite differently:

Pushback: Class action discrimination lawsuit filed against Gannett newspaper

1:34 pm

The Gannett logo abandoned in 2011
This Gannett logo was abandoned in 2011, for
one that eliminated any mention of equal employment.
We now know why.

“Segregation today, segregation tomorrow, segregation forever!” In what is certainly going to the beginning of a wave of lawsuits, five current and former Gannett employees, all white, have filed a class action lawsuit against the company, claiming its quota policies instituted in 2020 following the death of George Floyd are racist and discriminatory, favoring minorities over whites simply because of their race.

In the lawsuit, plaintiff Steven Bradley says he was fired from a management job at the Democrat and Chronicle newspaper in Rochester, New York, and then passed over for a different position with Gannett because he is white. Bradley in April filed a similar lawsuit against Gannett in New York state court. The status of that case was unclear.

Another plaintiff, Logan Barry, says he was in line for promotion to a leadership position at the Progress-Index in Petersburg, Virginia. After Gannett acquired the newspaper in 2019, the job went to a Black woman with fewer qualifications, according to the lawsuit.

The plaintiffs accused Gannett of violating a federal law prohibiting race discrimination in contracts. They are seeking to require Gannett to eliminate the 2020 policy, along with lost pay and benefits and other money damages.

Webb takes infrared image of Supernova SN1987A

10:04 am

Annotated infrared image from Webb
Click for original image.

The Webb Space Telescope has taken its first infrared image of Supernova SN1987A, the closest supernova to Earth in five centuries at a distance of 168,000 light years away in the nearby Large Magellanic Cloud.

The annotated image to the right, cropped, reduced, and sharpened to post here, shows that supernova remnant as Webb sees it. Most of the structures identified here have been observed now for decades as the material from the explosion has been expanding outward. However,

While these structures have been observed to varying degrees
by NASA’s Hubble and Spitzer Space Telescopes and Chandra X-ray Observatory, the unparalleled sensitivity and spatial resolution of Webb revealed a new feature in this supernova remnant – small crescent-like structures. These crescents are thought to be a part of the outer layers of gas shot out from the supernova explosion. Their brightness may be an indication of limb brightening, an optical phenomenon that results from viewing the expanding material in three dimensions. In other words, our viewing angle makes it appear that there is more material in these two crescents than there actually may be. [emphasis mine]

I highlight that one word because it is unnecessary, and is only inserted to punch up Webb’s abilities for public relations purposes. Moreover, the rest of the text of the full press release at the link is even worse. It provides little information about the evolution of this supernova since its discovery more than three decades ago, but instead waxes poetic again and again about how wonderful Webb is.

Though Webb certainly has much higher resolution than the earlier infrared space telescope Spitzer and can do far more, this tendency of NASA press releases to use these superlatives only devalues Webb. The images themselves sell the telescope. No need to oversell it in the text.

Meanwhile, the significance of SN 1987A is not explained. Since the development of the telescope by Galileo in the early 1600s, there has been no supernova inside the Milky Way. SN 1987A has been the closest, so it has been photographed repeatedly in multiple wavelengths to track the evolution of the explosion’s ejecta. Webb now gives us a better look in the infrared, though in truth the small amount of new details is actually somewhat disappointing.

Firefly notifies Space Force that it is ready to launch military payload at a moment’s notice

9:39 am

As part of a military program to improve the speed of launching payloads, Firefly and its payload provider Millennium have now notified the Space Force that both are ready to launch a satellite any time in the next six months, and do so fast.

Although this mission has been promoted as a 24-hour call-up, it is being planned in multiple stages and the companies have spent months rehearsing and preparing. The intent of the demonstration is to help the Space Force and the space industry contractors figure out processes to accelerate the planning and execution of national security missions.

Firefly and Millennium are now officially in a six-month “hot standby phase.” At any point during that time the Space Force will give the companies an alert notification, kicking off a 60-hour window to transport the payload to Firefly’s launch site at Vandenberg Space Force Base, California. conduct fueling operations and integrate it with the Alpha rocket’s payload adapter.

Space Force officials will then issue Firefly a launch notice with the final orbit requirements. Firefly will then have 24 hours to update the trajectory and guidance software, encapsulate the payload, transport it to the pad, mate to Alpha, and stand ready to launch at the first available window.

It appears that SpaceX has already done a similar thing with a fast classified launch several years ago, announcing the contract award and launching a classified payload within weeks. This new test is likely to show Firefly’s ability to do the same.

Vikram takes movie of Pragyan rover as it roves

9:30 am

Pragyan as seen by Vikram
Click for movie.

Using one of Vikram’s lander cameras, engineers have produced a short movie of India’s Pragyan rover as it rotated to avoid a small crater about ten feet ahead.

The picture to the right is from that 16-second movie, near its end. It appears that the engineers operating Pragyan were unhappy with almost any route ahead from its present position, as they rotated Pragyan almost 360 degrees, and even attempted forward motion at one point and then resumed rotation.

It is not clear if any of the craters visible in this picture are the crater that caused the detour. The movie however does provide a sense of scale. Pragyan is small, but it is able to maneuver easily using its six wheels.

China’s Long March 2D launches 3 satellites

8:55 am

China today successfully placed three “remote sensing” satellites into orbit, using its Long March 2D rocket lifting off from its Xichang spaceport in south China.

The state-run press provided no other information, including whether the rocket’s lower stages crashed near habitable areas. According to the flight path, the crash zones were near major population centers, including one city with a population of nine million.

SpaceX meanwhile scrubbed a Falcon 9 launch this morning at Vandenberg due to an issue with one first stage engine, but it is still scheduled to launch 22 Starlink satellites this afternoon from Cape Canaveral. The live stream is here.

The leaders in the 2023 launch race:

59 SpaceX
38 China
12 Russia
7 Rocket Lab

In the national rankings, American private enterprise still leads China in successful launches 68 to 38. It also leads the entire world combined, 68 to 61, while SpaceX by itself now trails the rest of the world (excluding American companies) 59 to 61 in successful launches.

The utter ignorance of modern educators on proud display the last two days in Colorado

3:32 pm

Jaiden and school official
Click to watch the video

In the last few days a story about a 12-year-old boy who was banned from classes because he had a Gadsden flag sticker on his backpack has gone viral, with the school, The Vanguard School, forced to cancel its parents night because of the outrage.

School officials had claimed that the Gadsden flag was not allowed at the school because it had “its origins in slavery and the slave trade,” a false statement of such utter ignorance of American history it leaves anyone with any education breathless with astonishment. The picture to the right shows the student Jaiden reacting in bemused disbelief at the moment that school official (in the background) made this absurd claim. He clearly knows more about American history than this brainless school official.

Not surprisingly, the uproar quickly caused the school’s board of directors to call an emergency meeting in which they backed down, especially as Jaiden had said he intended to continue to come to classes with the sticker on his pack, and would even do a sit-in if they dared try to kick him out again.

My purpose in mentioning this story however is to show how it illustrates so completely the bankruptcy of our education system today. Educators simply do not know American history, even though they are the people we expect to teach it. And when that ignorance is discovered, as in this case, they can’t just admit error and apologize, they have to equivocate and add more lies to their foolishness.
