Hubble to resume science operations using three gyros

Engineers have apparently figured out the issues with one of the Hubble Space Telescope’s three gyroscopes, and plan to resume science operations today using all three gyros.

After analyzing the data, the team has determined science operations can resume under three-gyro control. Based on the performance observed during the tests, the team has decided to operate the gyros in a higher-precision mode during science observations. Hubbleโ€™s instruments and the observatory itself remain stable and in good health.

This is excellent news. If it had been determined that the funky gyro was no longer functional, the telescope would have shifted into what the engineers call “one-gyro mode.” By using only one of the two remaining gyros, Hubble’s life could be extended. However, while it would allow the telescope to point and continue observations, the images would no longer be as sharp.

SpaceX launches 22 more Starlink satellites

SpaceX early in the morning on December 8th successfully launched another 22 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage successfully completed its twelfth flight, landing on a drone ship in the Pacific.

The leaders in the 2023 launch race:

91 SpaceX
56 China
16 Russia
7 Rocket Lab
7 India

American private enterprise now leads China in successful launches, 103 to 56, and the entire world combined 103 to 90. SpaceX by itself has once again taken the lead over the rest of the world (excluding other American companies), now leading 91 to 90.

At this moment, based on the pace SpaceX is setting, the chances it will make its goal of 100 launches in 2023 seems very likely. Not that it matters should the company fall short by one or two launches. At this moment it already has achieved more launches in a year than the entire world managed per year for most of the history of the space age, since Sputnik in 1957. It has also established that it can do this, which means its goal of 144 launches next year is quite reasonable.

Rachell Ellen Wong & Coleman Itzkoff – Hanukkah Medley

An evening pause: This piece seems appropriate for the first night of Hannukkah, which celebrates the miracle of the lights during the Maccabbean revolt against religious oppression, a revolt that led to the restoration of the Second Temple in Jerusalem, part of which still stands and is called by the Wailing Wall by many Jews. The medley includes two songs, “Oh Hanukkah,” and “Al Hanisim” (Thank You For the Miracles).

It also seems appropriate today, the anniversary of Pearl Harbor, as Israel itself responds in like kind to Hamas’s own infamous sneak attack and massacre on October 7th.

The steep mountain slopes inside Valles Marineris

Overview map

The steep mountain slopes inside Valles Marineris
Click for full image.

Time for another cool image showing the dramatically steep terrain of Valles Marineris on Mars, the largest known canyon in the solar system. The picture to the right, cropped, reduced, and enhanced to post here, was taken on October 31, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists rightly label this picture “Steep Slopes in West Melas Chasma”. The red dot marks the high point on this ridgeline. The green dot at the upper left marks the lowest point in the picture, about 4,800 feet below the peak. The blue dot on the right edge marks the low point on the ridge’s eastern flank, about 4,600 feet below the peak. The cliff to the east of the peak drops quickly about 1,300 feet in less than a mile.

On the overview map above, the white dot marks the location. The inset is an oblique view, created from a global mosaic of MRO’s context camera images, with the white rectangle indicating approximately the area covered by the picture above.

The immense scale of Valles Marineris must once again be noted. The elevations in this picture are comparable to the descent you make hiking down from the South Rim of the Grand Canyon. They pale however when compared to Valles Marineris. In the inset I have indicated the rim and floor of Valles Marineris in this part of the canyon. The elevation distance between the two is 18,000 feet.

In other words, the canyon to the east of this ridge is quite comparable in size to the Earth’s Grand Canyon, and it is hardly noticeable within the larger canyon of Valles Marineris.

Americans might finally be noticing the depravity in academia that has existed for more than two decades

Rick, stating the truth in Casablanca
Has the bankrupt testimony of three college
presidents finally awakened ordinary Americans?

For more than two decades conservatives have been reporting the growing immoral and depraved culture on the campuses of America’s most prestigious colleges, all to no avail.

These colleges instituted bigoted and racist policies of hiring, admissions, and funding that favored some races over others, so much so that today there are so few conservatives on their campuses that debate is impossible. The right has documented this repeatedly. Nothing was done.

These colleges worked to censor and silence the few conservatives that remained or came to speak as a guest, sometimes even allowing riots by leftist students to make sure such speech was prevented. The right has documented this repeatedly. Nothing was done.

These colleges further acted to remove and fire anyone, whether they were conservatives or not, who dared criticize any of the above actions. Often the terminations were done with no due process, and in direct violation of law and the colleges’ own rules. The right has documented this repeatedly. Nothing was done.

These colleges have steadily reshaped their curriculums so as to indoctrinate students into Marxism, “safe spaces”, and close-mindedness, instead of teaching the values of Western Civilization, liberty, the rule of law, personal responsibility, and most important, the requirement that an educated adult must be able to think critically. Students now come out of these colleges hostile to any debate, their minds closed to thinking because such thinking makes them uncomfortable.

The right has documented this repeatedly. Nothing was done.

As was the case in the early years of World War II, before the attack of Pearl Harbor (which occurred 82 years ago today), Americans were asleep. Then, Americans didn’t want to face the evil that was growing in Europe and threatened to engulf the world in war, and inevitably did so. Now, Americans have done everything they could to avoid facing the evil that has been growing in their own backyard. The result is the chaos we see today, with a younger generation that ignorantly believes America is the root of all evil, and that the best policies for the future should be censorship, socialism, and racial discrimination.

The situation has gotten desperate, and threatens to engulf us in another world war, potentially far more deadly than World War II. Worse, that war will be fought here, in America, from the start, because the enemies of Western Civilization have been deeply impregnated in our society by these corrupt colleges.

And as happened on December 7, 1941 when Japan attacked Pearl Harbor, it appears that something has finally happened that has at last maybe wakened Americans up. Our Pearl Harbor today might simply be the bankrupt clueless testimony of three college presidents in front of Congress on December 5, 2023.

First everyone must listen to the most revealing moments of that testimony. If you haven’t seen the video below, you need to watch it now. And if you have already seen it, watch it again. It is short, and quickly illustrates the moral depravity of the leadership at three of America’s most elite colleges, Harvard, MIT, and the University of Pennsylvania.

Musk touts SpaceX’s gigantic lead in sending mass to orbit in 2023

The mass sent to orbit in 2023
Click for original image.

In a tweet Elon Musk sent out yesterday, he noted that “SpaceX is tracking to launch over 80% of all Earth payload to orbit this year.”

The graphic to the right was included in Musk’s tweet. Despite the delays in developing its heavy-lift Starship/Superheavy rocket, mostly caused by government red tape since the arrival of Joe Biden in the White House, the company’s smaller Falcon 9 and Falcon Heavy rockets have still been able to launch more than fifteen times the mass into orbit that its nearest competitor, the nation of China.

I count launches by company or nation as a indicator of rocketry success. The mass-to-orbit metric is as important, if not more so, though the two are without doubt linked. Both measure the success of those trying to become major players in the launch market.

And in both metrics, SpaceX is wiping the floor with its competition.

The big 25th anniversary of ISS is really still two years away

In a press release today NASA touted the 25th anniversary of the mating in orbit of the first two modules of the International Space Station (ISS), Zarya (built by Russia but paid for by the U.S.) and Unity (built by Boeing for NASA).

25 years ago today, the first two modules of the International Space Station โ€“ Zarya and Unity โ€“ were mated during the STS-88 mission of space shuttle Endeavour. The shuttleโ€™s Canadarm robotic arm reached out and grappled Zarya, which had been on orbit just over two weeks, and attached it to the Unity module stowed inside Endeavourโ€™s payload bay. Endeavour would undock from the young dual-module station one week later beginning the space station assembly era.

Though this anniversary is nice, it really isn’t the most significant. The most significant ISS anniversary is still two years away, when we celebrate 25 years of continuous human presence in space. That record began on October 31, 2000, when a Soyuz-2 rocket lifted off from Baikonur in Kazahkstan, carrying American Bill Shepherd and Russians Yuri Gidzenko and Sergei Krikalev on what was to be the first crew occupancy of the station. Since that launch humans have occupied ISS without break.

With the present operation of China’s space station, and about four American commercial stations under development as well as plans by India and Russia to build their own, it is very likely that October 30, 2000 will remain the last day in human history where no human was in space.

That is the significant date. That is the moment in history that should be noted and marked as significant.

SpaceX initiates new round to obtain from $500 to $750 million in additional private investment capital

SpaceX has opened another tender round to obtain from $500 to $750 million in additional private investment capital, with the company now valued at $175 billion, up from the previous valuation of $150 billion.

With this new capital, the company will have raised at a minimum around $12 billion from private sources, not including the undisclosed investment in October from Italy’s biggest bank.

Why are private investors willing to do commit so much cash to this company? This quote from the article says it all:

SpaceX is on track to book revenues of about $9 billion this year across its rocket launch and Starlink businesses, Bloomberg News reported last month, with sales projected to rise to around $15 billion in 2024. The company is also discussing an initial public offering for Starlink as soon as late 2024 โ€” a bid to capitalize on robust demand for communications via space.

In other words, SpaceX is already earning enough to pay for the development of Starlink/Starship/Superheavy, with even bigger profits expected because it has such a lead on its competitors in the satellite broadband business.

These investors realize that SpaceX has captured the majority of this market share, and because of this it will be difficult for late arrivals like Amazon to enter the market. Amazon could charge less to gain market share, but SpaceX could then do the same. And SpaceX will already be in the black when it does so, while Amazon will instead be increasing its red ink.

This situation underlines the wisdom of Musk’s decision in 2018 to shake-up the management in SpaceX’s Starlink division because the management then was setting too slow a pace. As I wrote then:

Muskโ€™s desire for speed here actually makes very good economic sense. There are other companies developing similar internet satellite constellations, and if SpaceXโ€™s launches late they will likely lose a significant market share.

His concern about the slow pace seems to me also justified. This technology, while cutting edge, shouldnโ€™t require as much testing and prototype work as it appears the fired managers wanted. Better to get something working and launched and making money, introducing upgrades as you go, as SpaceX has done so successfully with its Falcon 9 rocket.

Time has now proven Musk right.

SpaceX launches more Starlink satellites

SpaceX tonight successfully launched another 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage successfully completed its ninth flight, landing on a drone ship in the Atlantic.

The leaders in the 2023 launch race:

90 SpaceX
56 China
16 Russia
7 Rocket Lab
7 India

American private enterprise now leads China in successful launches, 102 to 56, and the entire world combined 102 to 90. SpaceX by itself is once again tied with the rest of the world (excluding other American companies) 90 to 90. The fast pace in launches continues, however, with five launches scheduled in the next five days.

Pentatonix – Mary, Did You Know?

An evening pause: When I posted a different version of this song last year, I said this:

This song honoring Jesus I think really speaks of every child born on Earth, and how every parent should see them. As Wordsworth said, they come “trailing clouds of glory.”

Did you know that your baby boy has walked where angels trod?
When you kissed your little baby then you kissed the face of god.

Still applies, to my way of thinking. That there are people in the world that think it good to kill such things means only that those people need to be removed from human existence as quickly as possible, as they represent the worst evil anyone can conceive.

Hat tip Alton Blevins.
