On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Sadly the tweet tells us nothing about the capsule and its status. For all we know, this might not even be flight model, or it might be a smaller scale test capsule (which is what I think it is).
This module is essentially Tenacity’s service module. It will carry cargo into orbit, but will not return to Earth, but burn up in the atmosphere. Still no word on an actual launch date.
SpaceX today successfully launched 116 payloads, including 108 satellites, on its eleventh smallsat Transporter mission, its Falcon 9 rocket lifting off from Vandenberg in California.
The first stage completed its twelfth flight, landing back at Vandenberg. As of posting the satellites had not deployed.
The payloads included a wide variety of satellites and demonstration missions, including one orbital tug from the European tug company D-Orbit, its Ion tug deploying five satellites. In addition, five different companies will be using their own deployment equipment to release about fifty of the satellites from the Falcon 9.
These SpaceX Transporter smallsat launches demonstrate the value of lowering the cost to launch. Almost none of these satellites could have obtained investment capital when the cost high. Now that SpaceX has lowered that cost, a plethora of new satellite companies of all kinds can get that capital and build and launch their projects. And that burst of new companies is more than enough to provide business not only to SpaceX but to a lot of other new rocket startups.
The leaders in the 2024 launch race:
82 SpaceX
34 China

9 Russia
American private enterprise now leads the rest of the world combined in successful launches 97 to 52, while SpaceX by itself still leads the entire world combined, including American companies, 82 to 67.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 16, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
The scientists label this as “gullies previously identified in the walls of Harmakhis Vallis.” The gullies are obvious, the series of erosion features on the cliff wall. The cliff itself drops about 2,800 feet from the rim to the floor, and also appears to have internal horizontal layers that the gullies cut through.
What causes the gullies? Planetary scientists have a number of theories, none of which appear to explain the gullies everywhere on the Martian surface. They all appear in the mid-latitudes, where the most glaciers on Mars are found, and appear to be related to ice or frost freeze-thaw processes, with some gullies actually very ancient and formed when the planet’s rotational tilt was significantly different.

The uncertainty of science: New data using the Webb Space Telescope’s spectroscopic capabilities has provided a more refined measure of the expansion rate of the universe, dubbed the Hubble constant.
According to previous research, that rate could be anywhere from 67.4 to 73.2 kilometers per second per megaparsecs, depending on whether you rely on data from the Planck orbiter or that of the Hubble Space Telescope. Though this difference appears reasonable considering the uncertainties and assumptions that go into research that determines both numbers, astronomers have been unhappy with the difference. The numbers should match and they don’t.
Now new data from Webb suggests this difference really is nothing more than the margin of error caused by the many uncertainties and assumptions involved. That new Webb data measured the Hubble constant using three different methods, all similar to that used by Hubble, and came up with 67.85, 67.96, and 72.04, all in the middle of the previous two numbers from Hubble and Planck.
In other words, all the data is beginning to fall within this margin of error.
Astronomers are without doubt still going to argue about this, but it does appear that the research is beginning to coalesce around an approximate number. More important, in terms of cosmology these results confirm the theory that the expansion of the universe is accelerating (dubbed “dark energy” simply because it needs a name), since they confirm the method used to measure that expansion rate in the very distant universe.
Keep your minds open however. There remain many questions and uncertainties with all these conclusions. Nothing is settled, nor will it be likely for decades if not centuries.

"Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened." -- Arthur C. Clarke
According to a new study, the Chicxulub bolide that impacted the Yucatan 65 million years ago and is thought to have been a major cause of the extinction of the dinosaurs was likely a carbonaceous-type asteroid from beyond Jupiter.
The researchers attempted to pinpoint the nature of that bolide by analyzing the isotope samples from the thin layer of materials found worldwide that corresponds to the impact (dubbed the K-Pg boundary) as well number of different impact samples from different layers.
To address these questions, Mario Fischer-Gödde and colleagues evaluated ruthenium (Ru) isotopes in samples taken from the K-Pg boundary. For comparison, they also analyzed samples from five other asteroid impacts from the last 541 million years, samples from ancient Archaean-age (3.5 – 3.2 billion-years-old) impact-related spherule layers, and samples from two carbonaceous meteorites.
Ficher-Gödde et al. found that the Ru isotope signatures in samples from the K-Pg boundary were uniform and closely matched those of carbonaceous chondrites (CCs), not Earth or other meteorite types, suggesting that the Chicxulub impactor likely came from a C-type asteroid that formed in the outer Solar System. They also rule out a comet as the impactor. Ancient Archean samples also suggest impactors with a CC-like composition, indicating a similar outer Solar System origin and perhaps representing material that impacted during Earth’s final stages of accretion. In contrast, other impact sites from different periods showed Ru isotope compositions consistent with S-type (salicaceous) asteroids from the inner Solar System.
My headline poses this result as a question because these results are unconfirmed, and based on a very small sample of data. Nonetheless, this research not only gives us a better idea of the nature of the Chicxulub impactor, it does the same for a number of other important past impacts. That data in turn will help theorists refine their theories describing the early formation history of the solar system.
Sidebar: As always, there are numerous stories today in the mainstream press going ga-ga over this paper and declaring with certainty the utter truth of its conclusions. This of course is junk reporting, as there is no utter truth here, only some educated speculation based on some new data.
China today launched a new set of classified remote-sensing satellites supposedly designed to test “new technologies of low-orbit constellations, using its Long March 4B rocket lifting off from its Xichang spaceport in the southwest of China.
Almost no information was released about the satellites. Nor did China’s state-run press reveal where the rocket’s lower stages, carrying toxic hypergolic fuels, crashed within China.
The leaders in the 2024 launch race:
81 SpaceX
34 China
10 Rocket Lab
9 Russia
American private enterprise still leads the rest of the world combined in successful launches 96 to 52, while SpaceX by itself still leads the entire world combined, including American companies, 81 to 67.
These numbers will likely change in only a few hours, as SpaceX has another launch today, scheduled for 11:20 am (Pacific).
Due to some pressure from Congress (which wants the 450 jobs the project employs), NASA is now reconsidering its cancellation of the On-Orbit Servicing, Assembly and Manufacturing (OSAM) 1 mission, designed in the late 2000s to demonstrate the robotic refueling of a dead satellite but is so overbudget and behind schedule that in the interim private enterprise accomplished the same goal now repeatedly for a fraction of the cost.
Language in the final fiscal year 2024 appropriations bill, released just days after NASA’s cancelation announcement, which fully funded OSAM-1 at $227 million, directed NASA to adjust the mission to launch in 2026 within the spending profile NASA included in its 2024 budget request. That could be done, the report accompanying the bill suggested, through “potential de-scoping of some non-essential capabilities,” adding that if it is not possible, NASA should conduct another continuation review in September.
In other words, Congress wants NASA to keep this project, even if it means cutting the budget of other more useful and valuable missions.
OSAM has cost a billion dollars so far, and after almost fifteen years has not yet flown. Meanwhile, Northrop Grumman’s MEV servicing robot has already provided fuel to several dead satellites, while orbital tug startups are flying missions and developing the same refueling capabilities for far less. The industry doesn’t need this demonstration mission anymore. It has already demonstrated it, and done so better.
Moreover, why the heck does OSAM require 450 people? That number is absurd, and likely exceeds the payrolls of all the orbital tug companies plus Northrop’s robotic servicing division combined.
There is hope for the American taxpayer. The legislative recommendations above come solely from the Senate. The House appears less interested in spending this money. And NASA has not yet decided what it will do.
India today successfully completed the third and last test launch of its Small Satellite Launch Vehicle (SSLV), lifting off from its Sriharikota spaceport and carrying an experimental satellite designed to test a number of new technologies.
This launch is three-plus years late. It was originally to take place no later than 2021, but India’s space agency ISRO shut down entirely during the COVID panic, putting a halt on the rocket’s development. This delay also badly damaged ISRO’s attempt to grab the smallsat launch market. While it hid in basements in fear of a virus comparable to the flu, companies on the U.S. pushed to grab that market. Whether it can now grab its own market share is unclear, but the increased regulatory burdens that have appeared in the U.S. in the last three years gives it an opportunity.
This was India’s third launch in 2024, so the leader board in the 2024 launch race remains unchanged:
81 SpaceX
33 China
10 Rocket Lab
9 Russia
American private enterprise still leads the rest of the world combined in successful launches 96 to 51, while SpaceX by itself still leads the entire world combined, including American companies, 81 to 66.

Lockheed Martin today announced that it intends to purchase the satellite company Terran Orbital, of which it already owns one third of its stock.
Lockheed said Aug. 15 it would buy Terran Orbital for $0.25 per share in cash and retire the company’s existing debt. The deal, expected to close in the fourth quarter, has an enterprise value of $450 million. Shares in Terran Orbital closed Aug. 14 at $0.40.
Lockheed had six months ago offered to buy the company for $1 per share, but then withdrew the offer. It appears this new offer is intended to save the company, as Lockheed needs it. Right now 90% of Terran Orbital’s contracts are with Lockheed, and if the company goes under so do those deals.
This situation appears related to funding problems being experienced by the Rivada 300-satellite constellation. It had signed a $2.4 billion contract with Terran to build those satellites, but Terran removed that contract from its listed deals this week, suggesting that it no longer expected it to happen.
Lockheed Martin has made a strong effort in the past decade to remake itself to meet the challenges of the new space market, including entering the smallsat satellite manufacturing market. Thus it should be able to absorb Terran Orbital’s operations with little major harm to both, and much benefit.

Tim Dodd of Everyday Astronaut on May 30, 2024 was given a detailed tour by founder/owner Jeff Bezos of Blue Origin’s New Glenn factory at Cape Canaveral.
It is incredible to watch, because for the very first time, Bezos shows us what the company is finally doing to prepare for the first New Glenn launch, targeting no earlier than the end of September. Unlike every other visual shown of this facility in the past, this tour actually shows a factory floor where work is going on.
Much of the backgrounds inside the stages have apparently been put out of focus to protect Blue Origin’s proprietary rights. No matter.
As for the state of the manufacture of the BE-4 engines, Bezos stated that he expects next year to be building one engine every three days. Cross your fingers that he is right.
I have embedded the video of the tour below. Enjoy, and get excited by the competition and capability this rocket will create when it finally starts flying.

In the past few months the situation in the war between Russia and the Ukraine has had some significant battlefield events that suggested the situation is becoming unstable. First, Russia began an offensive campaign along the northern border of the Ukraine near the Ukrainian city of Kharkiv, pushing back into the same territory it had abandoned during its major retreat and defeats in the fall of 2022.
This offensive, combined with the gains Russia has made in the past few months in eastern Ukraine, suggested that it had completely recovered from those 2022 defeats, and was now moving forward in its effort to conquer the Ukraine in its entirety. At least, that’s how it seemed from a cursory outsider’s view.
Then, last month, the Ukraine launched its own offensive across the border into Russia’s Kursk region, the first time any Russian territory had been invaded since Russia’s unprovoked invasion of the Ukraine in February 2022. That same cursory view suggested that the situation was becoming unstable, and that Russia now faced a serious problem of its own.
To me, the only way to find out how serious these changes are since my last Ukraine War update six months ago, in February 2024, is to do another, and to compare the territorial changes on a map, as I have done every time previously.
Not surprisingly, a look at the map brings clarity to the situation.

Astronomers, both professional and amateur, have discovered a nearby star only 400 light years away that is moving so fast, 1.3 million miles per hour (almost three times faster than the Sun), it might very well escape the Milky Way and fly into intergalactic space in the far future.
The star, named CWISE J124909+362116.0 (or “J1249+36” for short), was first spotted by some of the over 80,000 citizen science volunteers participating in the Backyard Worlds: Planet 9 project, who comb through enormous reams of data collected over the past 14 years by NASA’s Wide-field Infrared Survey Explorer (WISE) mission. This project capitalizes on the keen ability of humans, who are evolutionarily programmed to look for patterns and spot anomalies in a way that is unmatched by computer technology. Volunteers tag moving objects in data files and when enough volunteers tag the same object, astronomers investigate.
J1249+36 immediately stood out because it was moving at about .1 percent the speed of light.
The star itself is either a very low mass red dwarf, or possibly a brown dwarf that never quite had enough mass to ignite as a star.
You can read the research paper here [pdf]. The researchers posit two possible explanations for the star’s speed. Either it was once part of a binary and thrown out when its white dwarf companion exploded as a supernova, or was once located in a densely packed globular cluster, where the interaction with other stars or even black holes could have flung it away.
Stoke’s Nova rocket
We’re from the government and we’re here to help you! The rocket startup Stoke Space appears to be struggling with the same kind of environmental red tape that is hindering SpaceX, though in Stoke’s case the red tape appears absurdly unnecessary.
Stoke is the only company besides SpaceX developing a rocket with both its first and second stages returning to Earth to land vertically and then be reused. Unlike SpaceX Starship/Superheavy, which is gigantic and revolutionary in all ways, Stoke’s Nova rocket is comparable in size to the hundreds of rockets that have launched from Florida since the 1960s. Based on that six-decade track record, it would seem that getting rights to launch Nova (but not for its return) would be considered basic and routine, requiring little complex bureaucracy.
Hah! Fooled you!
Before any of this can take place, the Space Force must complete its “environmental assessment” of the company’s plans at LC-14 [the launchpad used for John Glenn’s first orbital mission and many others subsequently], in order to evaluate how repeat launches will affect local flora and fauna. These assessments are mandatory under federal law, and they can often take months — but the upside is that they provide a closer look at a company’s operational plans.
ULA, which hopes to set a company launch record next year, is right now suffering a major loss of its launch crews to SpaceX and Blue Origin.
This year alone, ULA has lost about 45 of its 105 Launch Operations engineers — the people who test, assemble and prepare every rocket and its cargo to fly — at its primary launch site in Florida, according to the person, who asked not to be identified discussing non-public information. The lack of experienced personnel has postponed work for future missions, the person said.
The article says the loss of these launch crew employees is because of higher pay offered by the other companies, but I suspect a contributing factor is ULA’s low rate of launches in recent years (3 in 2023 and 4 so far in 2024). These people have nothing to do, and see the lack of work as detrimental to their future careers. Better to move on, either to SpaceX where a lot of launches occur, one almost every other day, or to Blue Origin, where the rocket is new and the company has plenty of cash.
The flight of crews could also be because people do not see a future at ULA. For almost a year there have been rumors that Boeing and Lockheed Martin, which own it jointly, want to sell it. It was thought that sale would happen after the first Vulcan rocket launch, but it did not. In recent months those rumors have subsided, suggesting that the interest in buying the company has trailed off.
Despite these problems, ULA’s problems could very well be temporary. Its manifest has a lot of launches scheduled, and once Vulcan is certified for the military and operational for all its customers, it is expected to be launching more than twice a month next year. If those launches take place as planned, these issues will be begin to vanish very quickly.
In fact, it does appear that if you are an engineering student with an interest in rocketry, your future is extremely bright. There will be plenty of work opportunities for you in Florida in the future, from any one these companies.
SpaceX this morning successfully launched two commercial high resolution Earth observation satellites for the company Maxar, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

This appears to be a bookeeping maneuver, but suggests that Rivada may be having problems, which is a big deal because its contract with Terran Orbital is for $2.4 billion to build 300 satellites.
This is one of those press releases about nothing. Maritime’s spaceport is years behind schedule. The release includes really no information, and appears to have been issued merely to counter another proposed Canadian spaceport, Nordspace, that recently released its own press release about nothing.
The goal is to do the first test launch in 2025.

Former Marion police Chief Gideon Cody,
apparently proud to emulate Nazi tactics
The wheels of justice ground slow, but grind they do: In August 2023 the entire police department of Marion, Kansas, performed a Gestapo-like raid of a local newspaper’s offices as well as the homes the town’s vice mayor, the newspaper’s 98-year-old owner Joan Meyer (resulting in her death the next day from a heart attack), and one reporter.
All the evidence suggested the police chief, Gideon Cody, had performed the raid as a personal favor to a local businesswoman, Kari Newell, who was worried that newspaper might publish a story about her arrest for driving while intoxicated and without a license. Newell and Cody then worked together to use the police and a local judge, Laura Viar, to harass and hopefully destroy a newspaper. The newspaper survived, but their actions ended up killing its 98-year-old founder.
The public outrage was instantanous. Cody was soon suspended, and if Newell wished to keep her history out of the papers this raid was exactly the wrong way to do it. The story went national, exposing her drunk driving history to the world. Meanwhile five different federal lawsuits were filed against Cody and various other county and city officials. The reporter, Debbie Gruver, also resigned from the newspaper, saying she no longer felt comfortable in the Marion community.
It now appears that Cody, who officially resigned in October 2023, has now been charged with a crime in connection with the raid.

Though a decision will not be made until next week, during a press briefing today the nature of the briefing and the wording by NASA officials suggested that they are now leaning strongly to having the two Starliner astronauts, Butch Wilmore and Suni Williams, return on the next Dragon capsule to launch to the station on September 24, 2024 and return in February 2025.
My conclusion is based on several subtle things. First, no Boeing official participated, the second time in row that they were excluded. Second, this briefing included some new individuals who rank higher in the chain of command, and whose opening statements were clearly written carefully in advance and were read aloud.
Third, and most important, the wording of those statements repeatedly indicated they are looking at Dragon return more seriously. For example, NASA’s chief astronaut Joe Acaba suggested strongly that the two astronauts were now well prepared for an eight month mission, rather than coming home in August 2024. Other statements by officials suggested they themselves are less confident about returning on Starliner. Though the data suggests they can return safely, there remains enough uncertainty to make some people uncomfortable.
One factor not stated but is certainly controlling the situation now is the upcoming election in November. The Democrats who control Washington and the White House will allow nothing to happen that could hurt their election chances. We must therefore assume people in the White House are now in control and are the ones who now intend to make the decision about Starliner’s return.
Based on these factors, we should expect NASA to announce next week that the crew will return in a Dragon capsule. In order for the return to happen on Starliner NASA and Boeing engineers must somehow convince those politicos that the return would be entirely safe. Since these politicos are always risk adverse, it would shock me if they can be convinced. It could happen, but understanding the politically framework is important.
The officials stated that they have scheduled the final review next week, and it appears the decision will be announced then.

The science team for the Mars rover Perseverance today outlined the planned route they intend to follow to bring the rover out of Jezero Crater.
The map to the right shows that route in red, with the rover presently at the upper right. Though Perseverance presently sits inside Neretva Vallis, which is the channel that cuts through the rim of the crater through which poured the delta material the rover has been sampling since landing, the route out of the crater will instead head south and west, crossing over the rim.
NASA’s Perseverance Mars rover will soon begin a monthslong ascent up the western rim of Jezero Crater that is likely to include some of the steepest and most challenging terrain the rover has encountered to date. Scheduled to start the week of Aug. 19, the climb will mark the kickoff of the mission’s new science campaign — its fifth since the rover landed in the crater on Feb. 18, 2021.
…Two of the priority regions the science team wants to study at the top of the crater are nicknamed “Pico Turquino” and “Witch Hazel Hill.” Imagery from NASA’s Mars orbiters indicates that Pico Turquino contains ancient fractures that may have been caused by hydrothermal activity in the distant past.
Rover looking back at the “Bright Angel” areaOrbital views of Witch Hazel show layered materials that likely date from a time when Mars had a very different climate than today. Those views have revealed light-toned bedrock similar to what was found at “Bright Angel,” the area where Perseverance recently discovered and sampled the “Cheyava Falls” rock, which exhibits chemical signatures and structures that could possibly have been formed by life billions of years ago when the area contained running water.
For Perseverance’s recent travels, go here.
Using the Webb Space Telescope, astronomers have detected evidence of hydrated minerals and even possibly a very tiny amount of water ice on the surface of the metal asteroid Psyche.
The Webb data point to hydroxyl and perhaps water on Psyche’s surface. The hydrated minerals could result from external sources, including impactors. If the hydration is native or endogenous, then Psyche may have a different evolutionary history than current models suggest. “Asteroids are leftovers from the planetary formation process, so their compositions vary depending on where they formed in the solar nebula,” said SwRI’s Dr. Anicia Arredondo, another co-author. “Hydration that is endogenous could suggest that Psyche is not the remnant core of a protoplanet. Instead, it could suggest that Psyche originated beyond the ‘snow line,’ the minimum distance from the Sun where protoplanetary disc temperatures are low enough for volatile compounds to condense into solids, before migrating to the outer main belt.”
However, the paper found the variability in the strength of the hydration features across the observations implies a heterogeneous distribution of hydrated minerals. This variability suggests a complex surface history that could be explained by impacts from carbonaceous chondrite asteroids thought to be very hydrated.
You can read the research paper here [pdf]. The actual amount of water possible is at most 39 parts per million and is also an order of magnitude lower than that found on the Moon, which strongly suggests that it comes from outside sources, such as impacts from other asteroids, not from the inherent geological history of Psyche itself.
The uncertainties of this research, which are large, which should be resolved when the probe Psyche, launched last year, reaches the asteroid Psyche in August 2029.
Link here. The report provides a lot of detail about the ramped up operations of Blue Origin in Florida in preparation for the first launch of New Glenn, previously announced as September 29, 2024. It appears the company is finally getting something done, and is getting closer to that launch.
Nonetheless, this detailed report makes no mention of that launch date. Furthermore, based on the work presently being done, it appears that launching by that date is impossible. With less than two months to go, the rocket has not yet been stacked and brought to the launchpad for even one dress rehearsal countdown. In March the company did tanking tests using an engineering test prototype, but so far such tests have not been done on the actual flightworthy rocket. It seems there will not be enough time to do them and meet that September 29th date.
The report also claims that Blue Origin “continues to ramp up testing its BE-4 and BE-3U engines” and “should have no problem supporting engine demand for both New Glenn and Vulcan,” but provides no hint as to the actual number of engines produced. Recent numbers suggest that ULA will have sufficient engines to launch its rockets, but will New Glenn, which needs seven BE-4 engines compared to the two needed for ULA’s Vulcan? We presently have no idea.
All in all, however, things at Blue Origin in 2024 appear to finally be happening, after a five year lull of nothing under the previous CEO, Bob Smith. Even if that launch doesn’t happen in September, it appears that it will happen sometime within the six months that follow.
VIPER’s now canceled planned route at the Moon’s south pole
The lunar lander startup Intuitive Machines has now revealed it is putting together an industry partnership to bid on flying NASA’s VIPER lunar rover on its own largest lander, still under development.
In an Aug. 13 earnings call about its second quarter financial results, Intuitive Machines executives said they were planning to respond to a request for information (RFI) that NASA issued Aug. 9 seeking input from companies and organizations interested in taking over the Volatiles Investigating Polar Exploration Rover (VIPER) mission that the agency said in July it would cancel.
Steve Altemus, chief executive of Intuitive Machines, said on the call that his company, which also responded to an earlier call for “expressions of interest” from NASA regarding VIPER, is working with other companies, universities and international partners on responding to NASA’s RFI. He did not identify any of those prospective partners.
…NASA, in its RFI, said that prospective partners would be responsible for the costs of any final testing and other work on the rover itself, as well as delivering it to the lunar surface and operating it once there. NASA, in its July 17 announcement that it would cancel VIPER, said the agency would save at least $84 million by halting work now on the rover, now complete and undergoing environmental testing.
Whether this company can raise the capital to finish this mission, now that NASA has said it cannot, remains unclear. That it is trying, and NASA is not, illustrates however why NASA should get out of the business of building anything and just buy it from the private sector. NASA’s attempt to build VIPER went 3Xs over budget and is considerably behind schedule. Now the private sector see profits in finishing the job, which will in turn save the agency considerable money. Imagine if NASA had done this from the beginning. The savings would have been even greater, and VIPER might right now be even closer to launch.

Apparently too many college students and teachers
support Hamas despite these very obvious facts.
Courtesy of Doug Ross.
Fight! Fight! Fight! At the website Campus Reform one of its reporters, Michael Duke, has been doing magnificent work in identifying in detail college by college the students and professors who rioted this spring on numerous university campuses in support of the terrorist organization Hamas and its October 7, 2023 massacre of more than 1200 people, including the rape, torture, and murder of men, women, children, and babies.
I thought it was time to do the public a service and provide a link to all of Duke’s reports, so that future employees will have a handy place to go to find out whether the future college prospect before them thinks it is acceptable to kill babies in support of an ideology.
