Russia launches military satellite

7:59 pm

Russia today successfully placed a classifed military satellite in orbit, its Soyuz-2 rocket lifting off from its Plesetsk spaceport in northern Russia.

The satellite is likely a reconnaissance satellite. No word on where the rocket’s core stage and strap-on boosters landed inside Russia, though launches from Plesetsk generally head north over very empty regions and the Arctic, and as the satellite appears to have an orbit with an inclination of 67 degrees that is likely in this case.

The leaders in the 2023 launch race:

86 SpaceX
53 China
15 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 84. SpaceX meanwhile maintains its lead over the rest of the world (excluding American companies) 86 to 84.

Did the Capitol police instigate violence by firing on peaceful January 6th demonstrators?

Video evidence recently released by House speaker Mike Johnson, combined with many videos taken by participants during the January 6, 2021 demonstrations on Capitol Hill, now suggest strongly that the violence was instigated by the DC police, not the January 6th demonstrators, who until then had been peaceful.

The video at the second link above ties together police bodycam footage with surveillance footage and smart phone footage — all time-stamped — and shows the Capitol security police firing on the demonstrators, who until that moment were doing nothing wrong and were simply standing in front of the Capitol in a crowd, chanting “USA! USA!”

Furthermore, the firing began at about 1:07 pm, eight minutes before Trump had finished giving his speech blocks away. The audience to his speech didn’t begin arriving at the Capitol until more than an hour later, when they found doors to the building open and security police welcoming them in.

Thus, the violence, set off by the police, had nothing to do with anything Trump said.

Striped terrain on Mars

12:39 pm

Overview map

Striped terrain on Mars
Click for original image.

Today’s cool image will be a mystery with the answer below the fold. Before you look at the answer, however, you must try to come up with your own explanation for the picture to the right, cropped to post here, that was taken on September 25, 2018 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

What we see in this picture is what looks like a striped terrain, alternating bands of light and dark. What caused the bands? Why the different colors?

The overview map above provides some clues. The white rectangle inside Juventae Chasma near the map’s center marks the area within which this picture was taken, though the picture to the right covers only about a pixel inside that rectangle.

Can you guess what these stripes reveal, from this little information? For this quiz to work you must make a guess, but be prepared to be wrong and quickly reassess your conclusions. Such is the real scientific method, so rarely taught now in schools.

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

8:45 am

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 launcherโ€™s upper and core stage tanks with liquid hydrogen (-253ยฐ Celsius) and liquid oxygen (-183ยฐ 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 6โ€™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

9:34 am

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

9:23 am

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

8:00 am

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.
