  • China announces plan to land humans on Moon before 2030

    • The officials claim they are working full speed on their manned lunar lander, the rocket, lunar spacesuits, etc. I have no idea if they will meet the date, but I agree with Jay, who wrote, “I bet they beat Blue Moon.”

New data gives the same result as old data: Like the flu, COVID hurt NO ONE who was young and healthy

1:19 pm

Lysenko with Stalin
Trofim Lysenko (on the left), the person now considered the ideal
scientific model by health officials, preaching to Stalin as he destroyed
Soviet plant research, persecuted anyone who disagreed with him,
and caused famines that killed millions.

New data from Israel has now confirmed what was obvious almost from the beginning, that COVID-19 was nothing more than a variation of the flu, a danger only to the elderly and the chronically sick.

According to newly revealed Israeli Ministry of Health data, during the entire epidemic there were zero deaths (that’s 0, nil, none, naught, zilch, null) from COVID to anyone under fifty who was of average and reasonable health.

Zero healthy individuals under the age of 50 have died of COVID-19 in Israel, according to newly released data. “Zero deceased of 18–49 years of age with no underlying morbidities,” the Israel Ministry of Health (MOH) said in response to a formal request from an attorney. Officials noted that the statement only applies to COVID-19 deaths where the MOH conducted an epidemiological investigation and had received information about the underlying diseases.

“Zero is a very, very clear number, and cannot be subject to interpretation,” Yoav Yehezkelli, a specialist in internal medicine and medical management, and former lecturer in the Department of Emergency and Disaster Management at Tel Aviv University in Israel, told The Epoch Times.

“Why were all the extreme measures of school closures, vaccination of children, and lockdowns needed?” he added. [emphasis mine]

This data simply confirms what numerous health experts unwilling to play political games with the data have said from the beginning, that COVID was essentially similar to the flu, harmless to healthy people and only a risk to the elderly and those with serious chronic health issues. Just like the flu, if you are healthy you have no reason to fear it, and in fact, you should be unbothered about getting it as it will give you natural immunity, thus making the spread of the virus more difficult and reducing the risk to those whom the virus (and the flu) could kill.

Trump — along with a lot of other Washington officials — proved this point when they all got COVID in October 2020 and quickly recovered. As I wrote then:

A typical glacier, on Mars

Overview map

A typical glacier, on Mars
Click for original image.

The cool image from Mars to the right, rotated, cropped, reduced, and sharpened to post here, provides us a good illustration of the lineated grooves that are typically seen on the surface of valley-confined glaciers, both on Earth and on Mars, and are also seen on the patched, grooved surface of Ganymede.

The picture was taken on March 13, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what appears to be a glacier flowing through a constriction. The arrow indicates the direction of the downhill grade.

The location, indicated by the white dot inside the inset on the overview map above, marks the location, in the western end of the 2,000 long northern mid-latitude strip on Mars I dub glacier country. In these three mensae regions (Deuteronilus, Protonilus, and Nilosyrtis) of chaos terrain practically every high resolution image shows features that resemble glaciers.

In this case, the glacial flow appears to be draining from a 10-mile-wide ponded circular valley though a narrow gap.

The grooved surface of Ganymede

9:39 am

The grooves of Ganymede
Click for original image.

Cool image time! The picture to the right, reduced to post here, was taken on June 7, 2021 when the Jupiter orbiter Juno did a close flyby of the moon Ganymede, taking four pictures.

Citizen scientists Gerald Eichstädt and Thomas Thomopoulos have now reprocessed parts of those images to bring out the details more clearly (the other new versions available here, and here).

I have chosen to highlight the picture to the right however because it so clearly shows the puzzling grooves that cover much of Ganymede’s surface. While these parallel grooves in many ways mimic the grooves often seen on top of valley glaciers on Earth and Mars, on Ganymede they do not follow any valley floor. Instead, they form patches of parallel grooves that travel in completely different directions, depending on the patch. At the moment their origin is not understood.

These grooves are one of the mysteries that Europe’s Juice probe will attempt to solve when it arrives in orbit around Jupiter in 2031.

SpaceX confirms Starship prototype to fly on next Superheavy test flight

9:19 am

SpaceX has confirmed that it will use Starship prototype #25 to fly on top of Superheavy prototype #9 on the next orbital test flight.

Starship #25 does not include a lot of the upgrades that have been installed on later Starship prototypes, but by using it SpaceX tells us its focus on that next orbital test flight will be to test Superheavy. Using this less capable Starship gets it used and out of the way so that the kinks in Superheavy can more quickly be worked out.

It also means SpaceX’s prime focus on that second flight will not be reaching orbit, though the company will try nonetheless.

The article at the link also notes that this next orbital test cannot take place any sooner than August, based simply on engineering requirements.

Ship 25 is now at the launch site and awaiting a six-engine static fire test, with Elon Musk noting the pad modifications should be complete in a month, ahead of another month of testing before the next test flight.

This gives the FAA two full months to approve the launch license. I predict however that come August, that launch license will still not be approved, and we will still have no clear idea of when that approval will come. Nor should we be surprised if approval does not come before the end of this year.

Webb detects large water plume released from Saturn’s moon Enceladus

9:10 am

Water vapor plume seen by Webb
Click for original image.

Using the infrared cameras on the Webb Space Telescope, astronomers have detected a surprisingly long and large plume of water vapor erupting from the tiger stripe fractures on Saturn’s moon Enceladus that scientists for years have detected vapor plumes.

The false color image to the right shows that plume.

A water vapor plume from Saturn’s moon Enceladus spanning more than 6,000 miles – nearly the distance from Los Angeles, California to Buenos Aires, Argentina – has been detected by researchers using NASA’s James Webb Space Telescope. Not only is this the first time such a water emission has been seen over such an expansive distance, but Webb is also giving scientists a direct look, for the first time, at how this emission feeds the water supply for the entire system of Saturn and its rings.

…The length of the plume was not the only characteristic that intrigued researchers. The rate at which the water vapor is gushing out, about 79 gallons per second, is also particularly impressive. At this rate, you could fill an Olympic-sized swimming pool in just a couple of hours. In comparison, doing so with a garden hose on Earth would take more than 2 weeks.

Though that rate of release sounds large, we must remember it is being released from a moon 313 miles across. From that perspective the rate of flow is quite reasonable.

Chinese launch yesterday set record for number of humans in space

8:59 am

The launch yesterday of three Chinese astronauts to that country’s Tiangong-3 space station established a new record, seventeen, for the number of humans in space.

The launch of the next crew to China’s Tiangong space station late Monday (U.S. time) added three astronauts to the population of humans in space, which reached a record number of 17 people in orbit — six Chinese citizens, five Americans, three Russians, two Saudis, and one Emirati astronaut.

The arrival of Chinese astronauts Jing Haipeng, Zhu Yangzhu, and Gai Haichao in space following their launch atop a Long March rocket broke the previous record of 14 people in orbit at one time.

Meanwhile, the four-person crew of the commercial AX-2 mission to ISS, has undocked from ISS, with SpaceX’s Freedom capsule expected to splashdown in the Gulf of Mexico at 11:09 pm (Eastern) tonight.

China sends a new crew to its Tiangong-3 space station

7:31 pm

Using its Long March 2F rocket, China today (May 30th in China) sent a new three-man crew to its Tiangong-3 space station for a five month mission.

The launch was from the Juiquan spaceport in the interior of China, so both the four side strap-on boosters as well as the core stage crashed somewhere in China. No word of any damage or injuries.

The Shenzhou capsule is expected to dock with the station about six hours after launch. The old crew’s stay will overlap with this new crew for a short time before returning to Earth.

The leaders in the 2023 launch race:

35 SpaceX
20 China
8 Russia
5 Rocket Lab

American private enterprise still leads China 40 to 20 in the national rankings, and the entire world combined 40 to 36. SpaceX alone now trials the rest of the world combined 35 to 36, but trails the entire world including American companies 35 to 41.

Sinking the Bismarck

6:01 pm

An evening pause: For Memorial Day, let’s have some history recounting one of the most important Atlantic naval battles of World War II, which took place 82 years ago this weekend. If the Bismarck had been successful in getting out into the Atlantic to attack convoys, Great Britain could very well have been starved into submission.

Hat tip Mike Nelson, who adds, “The ravages of WWII have faded from memory but we should never forget. Too many paid the price for the freedoms we so blithely take for granted.”

Cracking pedestal crater near Mars’ north pole

Cracking pedestal crater near Mars' north pole
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on March 18, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). I have also rotated it so that north is to the top.

Labeled a “terrain sample” by the camera team, this picture was likely taken not as part of any specific research project, but to fill a gap in the camera’s schedule so as to maintain its proper temperature. As usual, when the camera team needs to do this, they try to pick a target of interest. Sometimes they succeed, sometimes not.

In this case, the picture is of a location only about 800 miles from the Martian north pole, on the northern lowland plains. While the section shown to the right focuses on the largest crater, the full picture includes a few others, all of which appear to have their interior floors cracking in the same way, and all appear to be pedestal craters, sitting above the surrounding terrain, though by not as much.

How real is the Texas legislature’s proposed ban on the racist “Diversity, Equity, and Inclusion” programs at colleges?

11:27 am

Failure Theater!

Failure theater? This week the Texas legislature passed a proposed ban on race-based “Diversity, Equity, and Inclusion” (DEI) programs at its public colleges, requiring all such offices be closed within six months with the staff of such offices terminated.

The final legislation says universities cannot create diversity offices, hire employees to conduct DEI work, or require any DEI training as a condition for being hired by or admitted to the university. All hiring practices must be “color-blind and sex-neutral.” The bill would also prohibit universities from asking job candidates to provide written answers about how they consider diversity in their work or sharing how they would work with diverse populations, commonly known as diversity statements. Critics have equated diversity statements with ideological oaths, while supporters say they help ensure job candidates are prepared to support students from all backgrounds.

The legislation says university governing boards must adopt policies to discipline employees who violate these rules. Under the final version of the draft, university leaders cannot spend state money until they have declared to the state they are in line with the new law.

The bill still has to be signed by Texas’ Republican governor Greg Abbott, but that signature is expected.

Will this ban work? » Read more

China unveils next Shenzhou launch date and crew to its space station

9:07 am

China today revealed the next three-man crew to occupy its Tiangong-3 space station, with a planned launch in a Shenzhou crew capsule targeting May 30, 2023, Chinese time.

Because of time differences, that launch will occur tonight at 6:28 pm tonight, Pacific time. The rocket will be a Long March 2F taking off from China’s western interior Jiuquan spaceport. The rocket’s lower stages will therefore crash somewhere in China.

The crew will remain on board the station for five months, and with one astronaut the first Chinese to fly in space four times.
