Genesis cover

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.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"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

Fernando Ortega – Just As I Am

6:01 pm

An evening pause: A Christian’s prayer, set to beautiful music and performed live 2011. I post a lot of hard rock celebrating sex, drugs, and rock & roll, because the music and performance is great. I post this for the same reason. I wonder how many of my non-Christian readers will be open to listening and enjoying it.

Curiosity takes another look south into Gediz Vallis

2:18 pm

Looking south inside Gediz Vallis

Overview map
Click for interactive map.

Cool image time! As it has been more than a month since I lasted posted a cool landscape image from the Mars rover Curiosity, it seemed time to upload the panorama above, changed not at all to post here and taken by the rover’s right navigation camera on September 4, 2024.

The blue dot on the overview map to the right marks Curiosity’s present position. The yellow lines indicate the approximate direction of the panorama’s view. The red dotted line indicates Curiosity’s planned route, with the white dotted line marking its actual path. After spending most of the last month on a drilling campaign at the southernmost point of its travels, the science team had Curiosity retreat northward, where it will eventually head uphill to the west to swing around that mountain to head south in a parallel canyon.

The panorama looks into the slot canyon Gediz Vallis that Curiosity has been exploring for a little more than a year. The light colored mountains are what the scientists call the sulfate-bearing unit, a region on the higher slopes of Mount Sharp that is likely to have a very alien geology and chemistry, when compared to what is seen on Earth. Mount Sharp itself is beyond these peaks, not visible because it is about 26 miles away and blocked by these lower mountains.

Since landing on Mars a dozen years ago, the rover has traveled 20 miles and climbed about 2,500 feet. Getting to the top of Mount Sharp will therefore probably take more than one or two decades more of travel.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

A former Democratic Party majority leader in California sees the light

1:33 pm

The Democratic Party today
The Democratic Party today

If she of all people can do this, why can’t so many other ordinary Democrats? Gloria Romero, former Democratic Party majority leader in the California state senate from 2005 to 2008, announced publicly yesterday that she has dumped her lifelong allegiance to that party, switched her registration to the Republican Party, and furthermore enthusiastically endorsed Donald Trump for president. From her statement:

“Today I say ‘goodbye, adios,’ I’ve had enough. I am now another near-lifelong Democrat who is joining the growing number of people, including key groups like Latinos, who are leaving the Democratic Party. This is not the Democratic Party that I once championed. I do not recognize it anymore, and I cannot continue. I changed my voting registration today as the sun was rising to Republican, which has, under Donald Trump, become the champion of working people, the big tent. And indeed, I will vote for Donald Trump this fall.”

She proceeded to list the many tyrannical actions taken by the Democratic Party recently that led her to this decision, including its backroom deals that blocked any others from running against Joe Biden during the presidential primaries and then dumped him for Kamala Harris. She also cited that party’s support for the queer agenda, for “locking people up for free speech,” for supporting “endless war” everywhere, and for allowing an invasion of illegal immigrants, including violent felons.

Above all she cited the Democratic Party’s failed school policies, from favoring the school unions that do not educate kids but funnel money into the party’s campaign coffers to encouraging anti-Semitism at universities. “The Democratic party thrives off of this failure shamefully … even as our children fall farther and farther behind in reading, writing and the ability to compete internationally.”

None of her criticisms of the Democratic Party are wrong. » Read more

Woman arrested at Arizona city council meeting for exercising her 1st amendment rights sues

11:59 am

Rebekah Massie

(credit: Christine Hillman Photography).

Rebekah Massie, the woman who was arrested two weeks ago while attempting to speak during the open comment period at the city council meeting in Surprise, Arizona, has now sued the town’s mayor Skip Hall, the policeman who arrested her, and the city council for violating her 1st amendment rights.

The lawsuit, filed by her attorneys at the Foundation for Individual Rights and Expression (FIRE), can be read here. From FIRE’s press release:

FIRE’s lawsuit aims to permanently stop enforcement of the city policy used to silence Rebekah and obtain damages. In the meantime, FIRE moved for a court order to stop the city’s use of the policy while the lawsuit is pending. The lawsuit names the City of Surprise, Mayor Hall, and Steven Shernicoff, the officer who arrested Rebekah, as defendants. Quintus Schulzke, a Surprise resident who frequently makes public comments at city council meetings, also signed on as a plaintiff. Without legal intervention, Schulzke — or any other member of the public — risks arrest simply for speaking his mind to his elected representatives.

I have embedded the video of Massie’s arrest below. When I first reported this story I suggested Massie find a good lawyer and sue. It is great she wasted no time doing so. Even better, she is personally suing the mayor and the police officer who arrested her, and demanding punitive damages.

Mars loses hydrogen at very different rates, depending on the planet’s distance from the Sun

11:37 am

Hubble uv images of Mars atmosphere
Click for original image.

Scientists using data from both the MAVEN Mars Orbiter and the Hubble Space Telescope have determined that the rate in which Mars loses hydrogen and deuterium varies considerably during the Martian year, with the rate going up rapidly when the red planet reaches its closest point to the Sun. The picture to the right, reduced to post here, shows the data from Hubble.

These are far-ultraviolet Hubble images of Mars near its farthest point from the Sun, called aphelion, on December 31, 2017 (top), and near its closest approach to the Sun, called perihelion, on December 19, 2016 (bottom). The atmosphere is clearly brighter and more extended when Mars is close to the Sun.

Reflected sunlight from Mars at these wavelengths shows scattering by atmospheric molecules and haze, while the polar ice caps and some surface features are also visible. Hubble and NASA’s MAVEN showed that Martian atmospheric conditions change very quickly. When Mars is close to the Sun, water molecules rise very rapidly through the atmosphere, breaking apart and releasing atoms at high altitudes.

From this data scientists will be better able to map out the overall loss rate of water on Mars over many billions of years.

China significantly expands its international partners for its planetary program

10:34 am

According to China’s state-run press, it has recently signed cooperative agreements with a significant number of new nations for either its International Lunar Research Station project (ILRS) or other deep space planetary missions.

During the opening ceremony of a two-day space conference held in Tunxi, east China’s Anhui Province on Thursday, the China National Space Administration (CNSA) and its counterpart in Senegal signed an agreement on International Lunar Research Station (ILRS) cooperation.

At the conference, China’s Deep Space Exploration Lab (DSEL) inked memoranda of understanding with 10 institutions from countries including Serbia, Switzerland, the United Arab Emirates, Indonesia, Pakistan, Panama and South Africa. Also among the institutions are the Belt and Road Alliance for Science & Technology, the Foundation for Space Development Africa, and Africa Business Alliance.

Senegal is now the thirteenth nation to join China’s lunar base project, following Azerbaijan, Belarus, Egypt, Kazakhstan, Nicaragua, Pakistan, Russia, Serbia, South Africa, Thailand, Turkey, and Venezuela. That partnership also includes about eleven academic or governmental bureaucracies.

The agreements involving China’s deep space exploration involve other missions to other planets, with those nations either providing science instruments or some other contribution. That Switzerland and the United Arab Emirates have signed deals suggests there is a rising desire in the west to team up with China because of its general success in space, compared to the problems other nations often experience when dealing with NASA and the U.S. If so, the competition will certainly heat up in the coming years. I hope in this competition that American private enterprise can make up for the failures of our government.

Amateur astronomer detects changes in the reflective light coming off of NASA’s orbiting solar sail

10:20 am

Observations by amateur astronomer Marco Langbroek of Delft Technical University in the Netherlands has detected significant changes in the reflective light coming off of the giant orbiting solar sail that NASA engineers recently deployed in orbit.

I observed the Solar Sail again in the evening of September 1, 2024, and this time the brightness of the Solar Sail was quite different. As it rose in the south, it became very bright, reaching magnitude 0 (as bright as the brightest stars in the sky). It then faded again, and next displayed a slow brightness variation with multiple bright maxima and very faint minima.

…The brightness seems to indicate a slow cycle of around half a minute. … The brightness variation could be suggestive of a slow tumble or wobble (a gyration around an axis) that must have been initiated after August 29, when it appeared more steady (apart from a brief bright flare, probably due to a favourable sun-sail-observer geometry).

The sail, dubbed the Advanced Composite Solar Sail System, was launched on April 23rd, and after some initial technical issues it was deployed from its small cubesat on August 30th, expanding to 860 square feet.

The changes Langbroek detected have all occurred after that deployment, and suggest one of two things. Either the NASA engineers are testing the sail’s maneuverability, as planned, and thus the sunlight reflecting off it changes, or there is a problem controlling it that NASA has not yet revealed. We will have to wait to find out.

New questions raised about the rocket startup Relativity

10:06 am

Link here. Apparently Relativity has had a number of problems developing its proposed large Terran-R rocket using the 3D printing technology the company has specialized in.

According to internal documents reviewed by Ars, Relativity had difficulty printing pressure domes for the Terran R rocket. One of the documents references a “large buckling event” with a printed dome. As a result, Relativity seems likely to purchase these pressure domes from a European aerospace company.

The details provided for the status of Terran-R are somewhat vague. There are claims its size has been revised, and that the company is now outsourcing construction of some parts to European vendors, but none of this is described with any specificity. All in all however it does appear the rocket’s first launch is facing a delay from its 2026 targeted launch date. Earlier reports had suggested this, and this new report reinforces that sense.

I still wonder if Relativity might find much greater and more immediate success marketing its sophisticated 3D printing technology to other industries.

China targets 2028 for its own Mars sample return mission

9:56 am

According to a report today in China’s state-run press, it now hopes to launch its own Mars sample return mission in 2028, dubbed Tianwen-3.

The report is very vague about the missions design. It notes that it will involve two launches, including “key technologies such as collecting samples on the Martian surface, taking off from the Red Planet, [and] rendezvous on the orbit around Mars.”

Based on China’s overall track record for its planetary program, it is likely that the launch will likely take place somewhat close to this schedule, though a delay of one or two years would not be unreasonable. If so, we are looking at either two or three different projects to bring Mars samples back to Earth at almost the same time.

The first is the NASA/ESA joint Mars sample return mission, which is presently far behind schedule with large cost overruns, all because the mission design has been haphazard and confusing. At the moment it involves an American lander, a European orbiter and return capsule, a Mars launch rocket to be built by Lockheed Martin, and at least one Mars helicopter. None of this however is certain, as NASA is right now asking industry for suggestions for redesigning the mission. It is presently hoping to bring its samples back sometime in the 2030s.

The second is this China mission, which appears to have some of the same planned components, which is not surprising considering China’s habit of copying or stealing other people’s ideas.

A third sample return mission might also be flown, by SpaceX using its Starship spaceship and Superheavy rocket. Both are built with Mars missions specifically in mind. SpaceX has also ready done work locating a preliminary landing zone. If so, it could possible attempt this mission at about the same time, independent of both China or NASA.

Or it might simply offer Starship as part of the redesigned NASA sample return mission. There is also the chance SpaceX would do both.

If I had to bet, I would say SpaceX (on its own) is the most likely to do this first, with China second. If SpaceX teams up with NASA then it will be a close race between NASA and China.

New Glenn’s 1st stage ocean-landing platform arrives in Florida

9:37 am

Jacklyn docked in Florida
Blue Origin image of Jacklyn platform
docked in Florida. Click for original image.

Blue Origin yesterday released images of the arrival at Port Canaveral in Florida of the landing platform, dubbed Jacklyn, to be used by the first stage of its New Glenn rocket when it returns to Earth.

Jacklyn is 380 feet long and 150 feet wide (116 by 46 meters), according to Space Offshore. It’s named after the mother of Jeff Bezos, the billionaire founder of Blue Origin. (“Jacklyn” is a nickname, however; the ship’s legal moniker is “Landing Platform Vessel #1.)

Jacklyn is a new ship that was specially designed to be a New Glenn landing platform, Space Offshore reports. Construction on the ship began in Romania last year and wrapped up in Brest, France in the last month or so. Jacklyn departed Brest for Florida on Aug. 8.

The first launch of New Glenn is presently scheduled for October 13, 2024, and will carry two Rocket Lab-built Mars Orbiters for NASA. The launch window for these orbiters is only eight days, so there is not much margin in getting ready for that launch. The arrival of the platform in Florida in time for that launch suggests Blue Origin will attempt to land the first stage right from the start.

NASA confirms Europa Clipper launch on October 10, 2024 with questionable transistors

9:21 am

NASA yesterday confirmed that it has decided to go ahead with the October 10, 2024 launch of its $5+ billion Europa Clipper mission to Jupiter, despite the installation of transistors on the spacecraft that the agency knows are not properly hardened for that harsh environment.

Those transistors were built by a German company as part of equipment used by the spacecraft’s electrical system. Apparently that company hired a subcontractor to furnish the transistors, which failed to make them to the right specifications. Subsequent testing found that it is quite likely that at least some of the transistors will fail when Europa Clipper reaches Jupiter orbit.

It appears that NASA decided that the issue risk was small enough for the mission to achieve its minimal expected results, and decided the cost of delay and bad publicity replacing the transistors before launch would be worse than the limited science payoff and bad publicity that would take place years hence, when those transistors fail.

Remember this story in in 2030 when Europa Clipper enters Jupiter orbit and begins to experience problems.

Arianespace successfully completes the last launch of Avio’s Vega rocket

9:29 pm

Tonight the last launch of the Vega rocket, built by the Italian company Avio and managed by Arianespace, successfully lifted off from French Guiana, placing a European Earth observation satellite into orbit.

The launch was delayed several years because of a failure during a previous launch that required a major redesign of an engine. Further delays took place when Avio literally lost the tanks for the rocket’s upper stage, and had to improvise a solution (which has never been explained fully).

The rocket will now be replaced by the Vega-C, which after several more launches will be entirely owned and managed by Avio, which will market it to satellite customers without any significant participation of the government middleman Arianespace.

This was only the second launch by Europe in 2024, so the leader board of the 2024 launch race does not change.

86 SpaceX
37 China
10 Rocket Lab
9 Russia

American private enterprise still leads the rest of the world combined in successful launches 101 to 56, while SpaceX by itself leads the entire world, including American companies 86 to 71.

  • China touts an image taken by its Tianwen-1 Mars Orbiter

    • The location is in the high latitudes of the southern cratered highlands, and not surprisingly shows a scattering of craters. It was spring when the picture was snapped, so the mantle of CO2 dry ice that covers these high latitudes in the winter is beginning to sublimate away. The terrain itself looks like it is heavily impregnated with ice as well.

A channel of ice, water, or lava?

A channel of ice, water, or lava?
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on July 16, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows one small section of a Martian canyon approximate 750 miles long and dubbed Elysium Fossae.

The canyon walls at this spot rise about 3,300 to 3,800 feet from the canyon floor. The canyon itself is thought to be what geologists call a graben, initially formed when the ground was pulled apart to form a large fissure.

That’s what happened at this location, at least to start. This canyon is on the lower western flank of the giant shield volcano Elysium Mons. The cracks, which radiate out outward from the volcano’s caldera, likely formed when pressure from magma below pushed upward, splitting the surface.

That formation process however does not fully explain everything.

European rocket startup Maiaspace to begin tests of upper stage engine in ’25

9:58 am

The European rocket startup Maiaspace, a subsidary of ArianeGroup, has announced it will begin static fire tests of the upper stage engine for its Maia rocket in 2025, with a planned first launch before the end of that year.

The first stage of Maia is intended to be reuseable, and has been under development by ArianeGroup for the European Space Agency (ESA) for years.

The rocket’s first stage will essentially be the Themis reusable booster demonstrator, which is also being developed by ArianeGroup under an ESA contract. Initial hop tests of the Themis demonstrator had been expected to begin this year at the Esrange Space Center in Sweden. However, the first test of the demonstrator is now not expected until 2025. MaiaSpace will, as a result, have very little wiggle room in its schedule if it is to conduct an inaugural launch attempt next year.

Transitioning this first stage to a wholly private operation will certainly speed up its development, but the transition will take time.

Sierra Space completes acoustic testing of Shooting Star cargo module that will fly on first Dream Chaser launch

9:45 am

Sierra Space today announced that it has successfully completed acoustic testing of the Shooting Star cargo module that will fly on first ISS mission of its Tenacity Dream Chaser mini-shuttle.

During the Direct Field Acoustic Test (DFAN), the test team placed stacks of purpose-built loudspeakers – each one a highly-engineered acoustic device – in 21-ft-tall columns surrounding the spacecraft. Their goal was to test whether the structural elements of Shooting Star could withstand the acoustic environment of a launch on a Vulcan Centaur rocket. Over a four-day period, test engineers blasted the spacecraft with a controlled sound field that was 10,000x higher intensity than the volume of a typical rock concert, recreating the sonic intensity of a launch. Shooting Star withstood acoustic levels greater than 140 dB for several minutes at a time, proving its flight worthiness.

The press release however made no mention as to when the launch will actually take place. Sierra first got the contract to build Dream Chaser in 2016, and was supposed to make its first flight in 2020. That launch has been repeatedly delayed, and is now four years behind schedule. Supposedly it was to take place this year on the second launch of ULA’s Vulcan rocket in the spring of 2024, but was removed from that launch because of delays in preparing Tenacity for launch.

As of today, no new launch date has been announced, and though Sierra says Tenacity will be ready for launch by the end of this year, don’t expect it to happen before 2025.

Private company launches small test rocket from privately run sea-based platform

9:30 am

The rocket startup Evolotion Space on August 31, 2024 successfully launched a small test rocket from privately run sea-based platform operated by the Spaceport Company, a startup in itself.

The launch itself did not appear to reach space, but was instead designed to test both the rocket and the sea platform’s operation.

The experiment occurred approximately 30 miles south of Mississippi in the Gulf of Mexico. The test served to validate The Spaceport Company’s sea-based launch equipment and ground support equipment, said the company’s CEO and founder Tom Marotta. “Emerging hypersonic technologies require additional and larger test ranges to accommodate higher cadence testing campaigns,” he said. “With this new commercial facility, we will alleviate the burdens on government ranges and enable at-sea test environments that existing land-based ranges are unable to provide.”

The solid-fueled rocket meanwhile is being developed by Evolution to initially do hypersonic testing for the military.

NASA asks space industry for proposals on using the shelved Janus probes on mission to Apophis

9:23 am

NASA has now put out a request for proposals from the space industry for refitting the two Janus planetary probes, whose asteroid mission was shelved when its launch as a secondary payload was delayed due to problems with the Psyche primary payload, as a mission to the asteroid Apophis in connection with its April 13, 2029 close approach to the Earth.

NASA has been studying this new mission goal since early 2023, but apparently had failed to come up with a plan. It is now asking the private sector for suggestions on getting it done, including finding the funding for any plans.

Russia claims its next unmanned Moon mission, Luna-26, is on schedule

9:09 am

Phase I of China/Russian Lunar base roadmap
The original phase I plan of Chinese-Russian lunar
base plan, from June 2021.

According to Russia’s state-run press, its next unmanned Moon mission, Luna-26, is on schedule for a planned launch in 2027, though that press also claims the launch may happen in 2026 instead.

The problem with this claim is that Russia had for years said that this lunar orbiter would launch by 2025. As expected, the mission has not launched on time, as have all of Russia’s 21st century lunar exploration plans. For example, the previous lunar mission, the Luna-25 lunar lander, was originally supposed to land on the Moon in 2021, was not launched until 2023, and ended up crashing on the Moon when the spacecraft did not function properly during a engine burn in lunar orbit.

In the first phase of the so-called China-Russian partnership to explore the Moon, is shown by the 2021 graph to the right, China continues to do all the heavy lifting, and do so pretty much on the schedule predicted. Russian meanwhile continues to do what I predicted back in 2021, get nothing done on time and when launched have problems.

Williams-Sonoma sued over its racist DEI hiring policies

1:27 pm

The racist hiring policies at Williams-Sonoma, beginning with its board of directors and continuing all the way down
The racist hiring policies at Williams-Sonoma, beginning with
its board of directors and continuing all the way down

On September 3, 2024 the non-profit first amendment legal firm America First Legal (AFL) filed a complaint to the Equal Employment Opportunity Commission (EEOC) against the Williams-Sonoma corporation for its extensive DEI racial hiring policies that specifically favor some skin colors over others.

Williams-Sonoma, a kitchenware and home furnishings retailer with brands including Pottery Barn, Pottery Barn Kids, Pottery Barn Teen, West Elm, Williams Sonoma Home, Rejuvenation, Mark and Graham, and GreenRow, proudly represents to the public and its shareholders and investors that race, sex, and national origin are motivating factors in its hiring, employment, and contracting practices.

As outlined in Williams-Sonoma’s 2024 Annual Report, their Equity Action Plan and Equity Action Committee led to “approximately 68.1% of our total workforce identified as female and approximately 41.1% identified as an ethnic minority group.” The company boasts higher management, comprising “56.6% of Vice Presidents and above identified as female.”

Williams-Sonoma’s Equity Action Committee also appears to reward executives for making race, color, sex, or national origin a motivating factor in hiring and other employee practices. The Equity Action Plan tracked and set goals for the diversity of the company, board members, and board nominees. It then designed the “Associate Equity Network Groups” that benefit some workers and disfavor others, specifically white, male, and religious Americans.

In other words, this company demands race and sex be considered as a qualification for a job, regardless of the person’s skills, experience, or talent, and it also demands that whites and men be put on the back of the bus, considered last in all hiring decisions, merely because they are either white or male.

A frozen Martian splash

A frozen Martian splash
Click for original image.

Cool image time! The picture to the right, rotated, cropped, and enhanced to post here, was taken on July 11, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the southeast quadrant of a three-mile-wide unnamed crater that is surrounded on all sides by a dramatic but frozen splash apron of material, created when this impact occurred.

The rim rises between 200 to 400 feet from the surrounding plains, while the crater floor drops 700 feet to sit below those plains by 300 to 500 feet. In other words, that splash apron contains the material that was thrown up when the bolide drilled into the plain at impact, leaving behind this deep hole.

Why such a dramatic splash apron? Its existence suggests that the ground here was muddy, with a lot of water ice likely present. The location and wider context helps confirm this guess.

Two-lobed asteroid imaged by radar

10:04 am

Two-lobed asteroid
Click for original image.

During the August 18, 2024 first close fly-by of a potentially-dangerous asteroid only discovered back in May, astronomers used the Goldstone dish in California to produce the high resolution radar images shown in the picture to the right, reduced and sharpened to post here.

The images were captured when the asteroid was at a distance of 2.8 million miles (4.6 million kilometers), about 12 times the distance between the Moon and Earth.

Discovered by the NASA-funded Catalina Sky Survey in Tucson, Arizona, on May 4, the near-Earth asteroid’s shape resembles that of a peanut – with two rounded lobes, one lobe larger than the other. Scientists used the radar images to determine that it is about 980 feet (300 meters) long and that its length is about double its width. Asteroid 2024 JV33 rotates once every seven hours.

Asteroids formed as contact binaries, once considered the stuff of science fiction, have now been found to be relatively common, comprising about 14% of the near Earth asteroids larger than 700 feet across that have been radar-imaged. The refined orbital data suggests this asteroid might be a dead comet, though that conclusion is unconfirmed. That orbital data also tells us that though this object has the potential of hitting the Earth, it will not do so “for the foreseeable future.”

Scientists find oldest known reference to a solar eclipse dated approximately 6,000 years ago

In studying an ancient Hindu text called the Rig Veda that was compiled around 1,500 BC, scientists have found what they think is the oldest known reference to a solar eclipse, dated approximately 6,000 years ago.

You can read the peer-reviewed paper here [pdf]. From the paper’s conclusion:

We propose that the eclipse recorded in the Rig Veda refers to observations made of an eclipse around 4000 BC. By analyzing the description, we propose that the eclipse was the one that occurred in 4202 BC or else in 3811 BC. We propose that it was observed in Central Asia. To our knowledge, this is one of the oldest known references to a specific total solar eclipse mentioned in the historical literature.

The scientists came to this conclusion based on information contained and not contained in the Hindu text. The text noted the event occurred three days before the autmnal equinox, and that it occurred when that equinox occurred in the constellation Orion, when today the equinox occurs in the constellation Pisces. This reduced the number of possible eclipses to a small number during the time period around 4,000 BC. The text also lacked any mention of various Hindo myths explaining eclipses that appeared more recently, thus confirming this ancient date and telling the researchers that the nomadic people who compiled the Rig Veda were likely living in central Asia at that time.

The only two eclipses that fit the bill occurred on either October 22, 4202 BC or October 9, 3811 BC. This makes it the earliest known reference to an eclipse, far earlier than the possible eclipses that occurred in around 3340 BC and around 1300 BC.
