SpaceX and China complete launches

10:40 pm

Two successful launches today, first from China and then from SpaceX.

First, China launched what it called a”high-orbit internet services” satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China. No word where the rocket’s four strap-on boosters or core stage crashed in China.

Then SpaceX launched another 23 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral. The first stage successfully completed its 11th flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

19 SpaceX
10 China
3 Russia

American private enterprise still leads the entire world combined 22 to 19 in successful launches, while SpaceX remains tied 19-19 with the rest of the world, excluding American companies.

Today’s blacklisted American: Event by UC-Berkeley Jewish organizations is shut down by violent pro-Hamas rioters

They’re coming for you next: A lecture on international law by an Israeli attorney and former member of the Israeli Defense Force and organized by Jewish student groups at University of California-Berkeley (UC-Berkeley) was shut down on February 26, 2024 by a violent protest of about 200 pro-Hamas rioters, who broke down doors, attacked attendees, and forced the university to evacuate and cancel the event.

Jewish students at UC Berkeley evacuated from a campus theater Monday night after a mass of protesters, chanting “Intifada! Intifada!” and other slogans, shattered a glass door at the venue and shut down a scheduled lecture by an Israeli attorney who is also an IDF reservist.

Several students who were attending or working the event at Zellerbach Playhouse were injured, including two young women, one of whom sprained a thumb wrestling to keep a door shut as protesters tried to muscle it open. Another female student reportedly was handled around her neck, leaving marks. A third student said a protester spit on him.

Eventually the lecture did take place, at the home of a nearby rabbi, but was only seen by twenty.

A Martian cliff of ash, flushed by wind

1:13 pm

A Martian cliff of ash flushed by wind
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on December 27, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Described merely as an “exposed scarp” by the science team, this cliff edge is actually much more.

First some basic details. The elevation drop from the plateau down to the base of this cliff is about a thousand feet. The material that forms this plateau, scarp, and its base is all volcanic ash. The thicker sections of ash has caused its lower levels to compress, harden into a kind of sandstone. Near the surface however it is more friable, and like sandstone can break apart somewhat more easily.

The prevailing winds at this site are generally blowing to the south, but beginning to turn to the east, which explains the northwest to southeast orientation of the features.

The best analogy I can come up with to explain the erosion of this scarp is as follows: Imagine a deposit of dry mud a few inches thick on pavement. Take a leaf blower and blow at it hard, always in one direction. Eventually the outer edge will break up and blow away, leaving a sharp edge, that will also retreat with time as the wind continues to blow.

Here the winds are eroding that cliff, causing periodic avalanches which dissolve into sand that then blows away, leaving no debris pile at the base of the cliff. The ridges indicate harder material, that breaks away last, which is why there are some ridgelines extending outward from the scarp in line with these ridges. At the same time, these ridges of harder ash still break up with time, as some are cut off suddenly at the cliff edge.

Air leak in Russia’s half of ISS continues and has increased slightly

9:34 am

where the cracks have been found.

The leak in the Russia half of ISS continues to bleed air from the space station and has even increased slightly in recent months, though both NASA and Roscosmos say the rate of loss is tiny and poses no danger to the station’s inhabitants.

“There is no threat to the crew or the station itself,” [Roscosmos] said in a statement carried by Russian news agencies. Roscosmos’ statement followed comments by Joel Montalbano, NASA’s station project manager, who noted Wednesday that the leak in the Russian segment has increased but emphasized that it remains small and poses no threat to the crew’s safety or vehicle operations.

As indicated by the graphic to the right, the air loss is suspected to come from stress fractures in the Zvezda module, the station’s second oldest and one in which many dockings have occurred over the past two decades. Russia had suspended dockings in this port shortly after the leaks and cracks were detected, but have apparently resumed those dockings recently. One wonders if this new activity is contributing to the increase in loss of air.

Final images from Odysseus, lying on its side

9:23 am

One of three pictures downloaded after landing
Click for original picture.

In a press conference yesterday, NASA and the private company Intuitive Machines released three pictures taken by the Odysseus lunar lander after it came down a bit too fast, skidded on the ground so that one leg broke, and then tilted over.

The first images from the lunar surface are now available and showcase the orientation of the lander along with a view of the South Pole region on the Moon. Intuitive Machines believes the two actions captured in one of their images enabled Odysseus to gently lean into the lunar surface, preserving the ability to return scientific data.

The best picture, reduced and annotated to post here, is to the right. The spacecraft is tilted about 30 degrees from the vertical. Another picture showed the broken leg on the lander’s other side. The “two actions” mentioned in the NASA quote above refer to the issues that caused the broken leg: the limited ground data the lander used to land, and its larger than expected lateral speed.

The spacecraft is expected to be shut down by today because of lack of power and the advent of the long lunar night. Company officials remain hopeful it will come back to life when the sun rises in several weeks.

Officials from both NASA and Intuitive Machines have correctly noted that this was an engineering test mission, so even these failures make it a success in that the company can use them to improve the next lander. Nonetheless, it would have been nice if things had worked better on this first flight, especially because the problem that led to all the breakdowns, the failure to turn the lander’s range finding system back on after installation on the rocket, was an incredibly stupid human error that should not have happened at all.

National Science Foundation decides to fund only one giant telescope

8:56 am

The National Science Foundation (NSF) has decided that its astronomy program does not have sufficient funds for building both the Thirty Meter Telescope (TMT) in Hawaii and the Giant Magellan Telescope (GMT) in Chile, and will decide in May which one it will choose.

The GMT and TMT—both backed by consortia of universities, philanthropic foundations, and international partners—set out to build their next generation instruments in the early 2000s. But this privately funded approach, which during the 20th century produced the twin 10-meter Keck telescopes in Hawaii and the two 6.5-meter Magellan telescopes in Chile, stumbled when it came to multibillion-dollar projects. Although design work and mirror casting forged ahead, both projects failed to amass enough funding to complete construction. (A dispute with Native Hawaiians over the Hawaii site has also slowed the TMT.)

I predict that this decision puts the final nail in TMT’s coffin. That telescope was on schedule in 2015 — when construction was set to begin — to be already operational now, well ahead of GMT. The opposition in Hawaii by a minority of leftist protestors, who also had the backing of the state government (run entirely by the Democratic Party), blocked that construction even as the building of GMT’s mirrors proceeded.

Almost a decade later, while TMT sits in limbo, unbuilt, GMT is nearing completion, with its last mirror presently being fabricated and construction at its site now more than half done. It is expected to be finished by 2028, and is almost certainly going to get that NSF funding.

As I noted however in July 2023,

Not that any of this really matters. In the near term, ground-based astronomy on Earth is going to become increasingly impractical and insufficient, first because of the difficulties of making good observations though the atmosphere and the tens of thousands of satellites expected in the coming decades, and second because new space-based astronomy is going to make it all obsolete. All it will take will be to launch one 8-meter telescope on Starship and [GMT] will become the equivalent of a buggy whip.

The great tragedy of TMT is that the astronomers themselves at the project were not willing to fight that tiny minority of protesters, whose protests were based on the essentials of critical race theory that makes whites the devils and all other minorities saints. As academics trained in these insane ideas, the astronomy community accepted this bigoted premise, and out of guilt allowed those protesters to rule.

Russia launches weather satellite plus eighteen smallsats

8:37 am

Russia yesterday successfully launched a new weather satellite as well as eighteen smallsats, including one for Iran, its Soyuz-2 rocket lifting off from its Vostochny spaceport in the far east of Russia.

The rocket’s stages crashed in several designated drop zones within Russia and the Arctic Ocean.

The leaders in the 2024 launch race:

18 SpaceX
9 China
3 Russia

American private enterprise still leads the entire world combined 21 to 18 in successful launches, while SpaceX by itself is now tied with the the rest of the world (excluding other American companies) 18 all.

Inspector General: Mars Sample Return mission in big trouble

4:25 pm

The present plan for Mars Sample Return

Though the audit published today [pdf] by NASA’s inspector general of the NASA/ESA Mars Sample Return mission partnership tries to couch its language positively, the conclusion one reaches by reading the report is that the project is a mess and will almost certainly not fly when scheduled in 2029, and might even get delayed so much that the Perseverance rover on Mars — an essential component of the mission plan — might no longer be operational at that time.

First the budget wildly out of control.

The trajectory of the MSR Program’s life-cycle cost estimate, which has grown from $2.5 to $3 billion in July 2020, to $6.2 billion at KDP-B in September 2022, to an unofficial estimate of $7.4 billion as of June 2023 raises questions about the affordability of the Program.

In addition, the audit noted that this is not the end, and that based on another independent review the budget could balloon to $8 to $11 billion before all is said and done. (I will predict that as presently designed, that budget will likely reach $15 billion.)

Today’s blacklisted American: “Progressive” leftists in Seattle can’t even take a joke, blackballing four comedians

1:08 pm

Cancelled comedians
Click for original video.

They’re coming for you next: Not surprisingly, a comedy club located in the heart of Seattle, in the very same CHAZ neighborhood (Capitol Hill Autonomous Zone) that leftist Antifa thugs took over in 2020 after the death of George Floyd, has cancelled the scheduled appearance of four comedians, apparently because all four were considered too moderate and not “progressive” enough for that radical community of close-minded fascists. As rationalized in an email to the comedians, comedy club officials explained:

Capitol Hill is known for its progressive values, and we’ve received significant feedback expressing concerns about the alignment of these upcoming shows with the neighborhood’s ethos. This feedback includes concerns from local advocacy groups that are deeply embedded in our community and work towards upholding its values.

Given the feedback and to avoid any potential negative impact on both our club and the artists involved, as well as to maintain the harmony within our community, we believe the most responsible course of action is to not move forward with the shows for Dave Smith on April 11th, Luis J Gomez for May 31st-June 1st, Jim Florentine for September 20th-21st and sadly Kurt Metzger on October 11th-12th as well.

The email also added most dishonestly, “We truly value the art of comedy and the diverse perspectives it brings to our lives.”

What a crock. » Read more
