Ariane-6’s core stage completes full 7 minute engine test

Engineers yesterday successfully completed a two-hour dress rehearsal countdown and fueling of an Ariane-6 first stage followed by a full seven minute engine burn, simulating what that stage would do during a launch.

The test took place on Ariane-6’s launchpad in French Guiana.

The November 23 test sequence was run the same way as the previous ones, with a launch sequence and final countdown representative of a launch, including removal of the mobile gantry and filling the launcher’s upper and core stage tanks with liquid hydrogen (-253° Celsius) and liquid oxygen (-183° Celsius). The test ended with the ignition of the core stage Vulcain 2.1 engine, followed by more than 7 minutes of stabilized operation covering the entire core stage flight phase. All functional aspects of Ariane 6’s core stage during the flight phase were tested.

According to the European Space Agency, only one more engine test of the Ariane-6’s upper stage remains before the spring launch can be attempted, and that engine test is planned for next month in Germany.

With the retirement of the Ariane-5 rocket in July, Europe has had no large rocket to launch payloads. Originally Ariane-6’s first launches were supposed to be in parallel with Ariane-5’s last launches, but its development is four years behind schedule.

China delays till ’25 the launch of its Hubble-class optical space telescope

China today revealed that it is delaying the the launch of its Xuntian space telescope from early next year to 2025.

Zhan Hu, project scientist of Xuntian space telescope system, revealed that the delay was necessary for the team to finalize a preflight “engineering qualification model.” This model will undergo rigorous performance tests early next year. Despite the setback, China is making significant strides by domestically developing all five instruments for Xuntian, a first for the country, Scientific American reported.

The optical telescope, designed to somewhat comparable to Hubble, is intended to fly close to China’s Tiangong-3 space station where astronauts will periodically fly over to do maintenance and repair. Its primary mirror, two meters in diameter, is only slightly smaller than Hubble’s 2.4 meter mirror.

The article says the launch was supposed to happen before the end of this year, but that is incorrect. The launch has been targeting the spring of 2024 since February.

China launches classified satellite

China today used its Long March 2D rocket to launch what it described as “a technology experiment satellite for satellite internet technologies”, the rocket lifting off from its Xichang spaceport in the southwest of China.

No other information was released. While the satellite could be a test satellite for a constellation comparable to Starlink, the lack of information suggests otherwise.

No word also on whether the rocket’s first stage, using toxic hypergolic fuels, landed near habitable areas. The drop zone was over heavily populated areas in China.

Furthermore, China’s Kuaizhou-1 rocket had also been expected to launch today from Xichang in the wee hours of the morning, also carrying a classified payload. No word yet on whether that launch occurred, was scrubbed, or was simply the Long March 2D launch, the name of the rocket misunderstood prior to launch because of China’s secrecy.

Putting that unknown launch aside, here are the present leaders in the 2023 launch race:

86 SpaceX
53 China
14 Russia
7 Rocket Lab
7 India

American private enterprise still leads China 98 to 53 in successful launches, and the entire world combined 98 to 83. SpaceX by itself still leads the rest of the world (excluding American companies) 86 to 83.

Abraham Lincoln proclaims a day of Thanksgiving in the middle of the Civil War

Abraham Lincoln
Abraham Lincoln

The date was October 3, 1863. The Civil War was at its height, with no end in sight and no clear sign yet of victory for the Union. For all anyone knew, the great American experiment in self-government, freedom, and constitutional law was about to end in failure, with one half of the nation continuing on founded on the idea that it was okay to enslave other human beings, based on their race.

In such a moment, President Abraham Lincoln did what all past leaders in America had done, call for a day of prayer to God for the future while giving thanks for the blessings still abounding. For this purpose he set aside the last Thursday of November of that year.

Since then, Americans have never stopped celebrating Thanksgiving on that day. Today comes another Thanksgiving during a time of chaos, hate, violence, and oppression. There is much to invoke horror and outrage.

There is much more to be thankful for. As much as some have tried to squelch freedom here in America and abroad, all signs say that freedom-lovers everywhere are refusing to go down without a fight. Let us join together to renew that effort, so that “government of the people, by the people, for the people, shall not perish from the earth.”

Below is Lincoln’s Thanksgiving proclamation. If only we had leaders today who could think and write with similar elegance and humility.
—————————–
A Proclamation.

The year that is drawing towards its close, has been filled with the blessings of fruitful fields and healthful skies. To these bounties, which are so constantly enjoyed that we are prone to forget the source from which they come, others have been added, which are of so extraordinary a nature, that they cannot fail to penetrate and soften even the heart which is habitually insensible to the ever watchful providence of Almighty God.

November 22, 2023 Quick space links

Courtesy of BtB’s stringer Jay, who with I wish everyone a great Thanksgiving tomorrow.

 

 

 

 

  • Blue Origin shows off the now welded first stage tanks of its New Glenn rocket
  • It is assumed these are for the first launch, whenever that might be. Since there are no workers on the factory floor, Jay speculates it was taken after hours. I wonder, since this lack of activity has been seen in every such picture of this rocket assembly operation. I really wonder how many people even work there.

 

  • Jeff Bezos sells off $240 million more Amazon shares
  • Though the reporters on the CNBC video at the link speculate this money is for Blue Origin, there is no evidence of this. In fact, recently Bezos has appeared to donate almost all his stock sale cash to leftist political charities, not Blue Origin.

Martian ice sheets sublimating like peeling paint?

Overview map

Martian ice sheets resembling paint peeling
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on September 19, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The features are described as “ribbed terrain” in the label. To my eye they more resemble flakes of peeling paint, most especially the mesas in the lower left. On the full image there are many more examples that resemble old paint peels, barely attached to the wall.

The white dot on the overview map above marks the location, deep inside the 2,000-mile-long strip in the northern mid-latitudes I dub glacier country, because everything seems covered by glacial features. This location is at 42 degrees north latitude, where plenty of near-surface ice features are found on Mars.

At first glance it looks like the top “paint-peel” layers to the south have been slowly sublimating away, leaving behind the smooth plain to the north. The problem is that this smooth area in the full image actually appears to be a glacial ice sheet of its own, filling all the low areas between mesas.

In other words, we are probably looking at layers and layers of ice sheets, each created during a different Martian climate cycle, caused by the wide swings of the planet’s rotational tilt, or obliquity.

The location is within Arabia Terra, the largest transitional zone on Mars between the northern lowland plains and the southern cratered highlands. Thus it sits above the glaciers that fill the lower regions of chaos to the north. What we have here is terrain that will eventually become chaos terrain, as the narrow faults and cracks are slowly widened into canyons by the cycles of glacial activity.

Real pushback: Soldiers punished by Biden for refusing jab now sue for billions

Fighting the left's playbook
Fighting the left’s playbook

Bring a gun to a knife fight: The many military soldiers punished by Biden for refusing the Covid jab have now filed a class action lawsuit for what they expect to be worth billions.

Former troops are suing the U.S. government for lost pay and benefits due to the Biden administration’s military vaccine mandate, one of the lawyers who successfully brought down the Anthrax vaccine told Breitbart News.

Attorney Dale Saran, a retired Marine, and fellow attorneys Andy Meyer and Brandon Johnson are representing the former troops in three separate lawsuits they plan to turn into a class action lawsuit on behalf of all service members who were either kicked out or illegally ordered to stop drilling, resulting in loss of pay or benefits. Saran said the amount is in the “billions.”

“It’s worth billions. That’s just flat-out. That’s what it is in backpay. It’s billions of dollars,” he said.

Though only about 8,000 active-duty troops were kicked out of the military due to the Biden jab mandate, the lawyers estimate another 80,000 to 100,000 soldiers are due compensation for lost benefits because they were made inactive or forbidden from participating in drill activities.

The lawsuit has been filed in U.S. Court of Federal Claims, a specialized court where illegal military discharges are heard. Lawyer Saran won a similar suit in that court over the military’s anthrax mandates back in the late nineties. The case now is likely stronger because, as he notes,

They were basically [without] the benefit of any due process. No boards were held. They didn’t hold any administrative separation boards; they didn’t hold any hearings. They didn’t do any federal recognition boards; none of the administrative or judicial procedures were used. They just flat-out did it.

This willful refusal to follow the law has been typical behavior by the left since the start of the Wuhan panic. The law no longer applies to them. They want to do something, they do it, even if it is illegal and hurts someone else. Shutter businesses illegally, silence opponents illegally, favor some races illegally, fire soldiers illegaly, mandate jabs and masks illegally, demand health records illegally: All okay because the good people are doing it! How dare you question their righteousness?

The worst aspect of these violations of law has been the meek willingness of everyone to go along with them. Most shameful.

Eutelsat-OneWeb gets license approval in India

Less than two weeks after SpaceX obtained regulatory approval to offer its Starlink system in India, Eutelsat-OneWeb (newly merged) has now gotten its own approval.

Eutelsat-OneWeb is half owned by an Indian investment firm, so it is no surprise it obtained this approval soon after SpaceX. The two companies will now be competing aggressively for business in this giant country, whose technological capabilities has been renewed in recent years by the abandonment of a socialist/communist government for a leadership focused on encouraging freedom, capitalism, and competition.

NASA laser communication experiment succeeds in sending data from beyond Moon

A NASA laser communication experiment on the asteroid probe Psyche succeeded on November 14, 2023 in sending data to and from the spacecraft as it traveled away from Earth.

NASA’s Deep Space Optical Communications (DSOC) experiment has beamed a near-infrared laser encoded with test data fromnearly 10 million miles (16 million kilometers) away – about 40 times farther than the Moon is from Earth – to the Hale Telescope at Caltech’s Palomar Observatory in San Diego County, California. This is the farthest-ever demonstration of optical communications.

Riding aboard the recently launched Psyche spacecraft, DSOC is configured to send high-bandwidth test data to Earth during its two-year technology demonstration as Psyche travels to the main asteroid belt between Mars and Jupiter. NASA’s Jet Propulsion Laboratory in Southern California manages both DSOC and Psyche.

The experiment seeks to demonstrate the advantages of optical communications, which if successful could have data speeds ten to a hundred times faster than standard high band radio communications. While the technology has been demonstrated as far away as the Moon, this is the first successful test from deep space, a key advance that suggests the technology is becoming mature enough to use on planetary missions.

If so, it could largely replace or at least supplement the various radio-antenna networks on Earth, such as NASA’s Deep Space Network, with smaller and more efficient communication links.
