The cohort of Silicon Valley tech titans who have been hoovering up Bay Area farmland in the hopes of converting it into a new city have been accused of deploying “strong-arm tactics” and a “divide-and-conquer” strategy to gobble up as much acreage as possible. A number of local farmers say Flannery Associates, the parent company behind the quixotic California Forever project, has used underhanded tactics in its pursuit of a regional real estate hegemony. The allegations were divulged in a recent court filing connected to a lawsuit involving the land disputes.

In August, the New York Times reported that Flannery, which was then a totally mysterious company, had managed to buy up $800 million of farmland in the Solano County region. The Times also revealed that Flannery was backed by a coterie of influential Silicon Valley billionaires, including folks like Marc Andreessen, Reid Hoffman, and a variety of other big names in the tech industry. Flannery’s grand plan, it was revealed, was to use the land it had purchased to create a utopian new city, which the Flannery cohort is calling “California Forever.” This supposed city is purely hypothetical for now, but its backers say that one day it could be a beautiful, bustling city of the future.

Of course, the first step to building this new libertarian wonderland was to buy up as much land as possible, and to do that, Flannery had to buy out the people who were already living there. For the most part, the folks who were already living there were the operators of longtime, family-owned farms.

In some cases, negotiations between the company’s lawyers and prospective sellers did not go the way Flannery wanted it to go and, in May, the company sued a number of the farmers, claiming that they were engaged in anti-competitive practices and price fixing. The farmers, in turn, have accused the billionaire-backed corporate entity of trying to bully and manipulate them and their families into selling away their land. In the recent court filing, the farmers dismissed the lawsuit’s claims, alleging that Flannery had repeatedly engaged in “strong-arm tactics” in an effort to pry loose the land.

Such tactics allegedly included attempts to “play one family against another by misrepresenting the families’ intentions regarding Flannery’s offers, in hopes that families otherwise unwilling to sell would feel pressure not to disappoint their friend and neighbor,” the filing states. In one specified case, the farmers claim Flannery approached one family member, acquired an eighth of a large tract of family-owned land from them, then sued the other seven members of the family in an attempt to acquire the full parcel.

On its website, California Forever has denied the charge that it acted in any way untoward, instead characterizing the farmers in question as “a small group of individuals [who] have engaged in a targeted campaign to slander Flannery Associates” and who are engaged in a nefarious “secret conspiracy.”

In general, it seems really hard to imagine that this project will ever materialize. Even if Flannery somehow manages to smooth things over with the locals, the project still needs to clear a number of state and regional regulatory hurdles. Those hurdles are looking dubious, since a lot of local politicians have expressed doubts about the viability of the project. If those hurdles, somehow, are cleared, the project’s backers then have to actually build the majestic metropolis that developers are envisioning. After that, people have to move there and the city has to retain a certain level of population density for the foreseeable future. Then the city’s creators have to actually, like, run the city…you know, forever.

This inspires a whole lot of questions. For instance, will California Forever have a government? If so, what kind of government is it going to be? Or is it just going to be some sort of corporately owned series of planned communities, sorta like an expanded version of Disney’s Storyliving? The whole thing seems like a giant expensive mess that is doomed to fail but I guess you should never count out the disruptive potential of a tech mogul’s unquenchable hubris.

Dream Chaser, built by Sierra Space, is being prepped for transport to a NASA facility in Ohio, where it will undergo a series of tests to make sure the spaceplane can survive its heated reentry through Earth’s atmosphere. Starting these tests is crucial, demonstrating Dream Chaser’s readiness for flights and potentially transforming commercial space travel.

Sierra Space is hoping to see its spaceplane fly to the International Space Station (ISS) in 2024 as part of a contract with NASA. The first commercial spaceplane is currently at the company’s facility in Louisville, Colorado, and will soon make the roughly 60 mile (96 kilometer) journey to the Neil Armstrong Test Facility in Sandusky, Ohio, local media outlet Denver 7 reported.

The Colorado-based company was awarded a NASA Commercial Resupply Services 2 (CRS-2) contract in 2016, under which it will provide at least seven uncrewed missions to deliver cargo to and from the ISS. Sierra Space is targeting 2024 for the inaugural flight of the first model of the Dream Chaser fleet spacecraft, named Tenacity, from the Kennedy Space Center in Florida.

At the company’s facility, the spaceplane is finally coming together. “We’re almost done with everything,” Angie Wise, Sierra Space’s chief safety officer, told Ars Technica on Monday. “We’re finishing all the closeout panels. We’re essentially getting it ready for shipping. We’ve checked out the landing gear. We’re going to put everything back in, stow it, and then move it onto the (transport) fixture and get it out of here.”

Tenacity will stay at NASA’s Neil Armstrong Test Facility for one to three months, during which engineers will test the spaceplane’s ability to withstand the vibrations and acoustics of a rocket launch, as well as the temperature extremes it will experience during flight, according to Ars Technica. The spaceplane will be placed inside a giant thermal vacuum chamber. In June, Sierra Space will put its Dream Chaser spaceplane to the test, powering it up for the first time at the company’s test facility.

Dream Chaser is designed to fly to low Earth orbit, carrying cargo and passengers on a smooth ride to pitstops such as the ISS. The spaceplane will launch from Earth atop a rocket, and is designed to survive atmospheric reentry and perform runway landings on the surface upon its return. Sierra Space’s Dream Chaser is designed with foldable wings that fully unfurl once the spaceplane is in flight, generating power through solar arrays. The spaceplane is also equipped with heat shield tiles to protect it from the high temperatures of atmospheric reentry.

Unlike Virgin Galactic’s suborbital spaceplane, Sierra Space designed Dream Chaser to reach orbit and stay there for six months. The U.S. Space Force has its own spaceplane, which wrapped up a mysterious two-and-a-half-year mission in low Earth orbit in November 2022.

The commercial spaceflight industry may not be too focused on spaceplanes as companies race to design fully reusable rockets, but spaceplanes do have an advantage of a smooth landing on their way back down to Earth. In terms of those exact advantages, spaceplanes offer safety, efficiency, operational flexibility, and potential for future commercial opportunities.

For its debut flight, Tenacity will ride atop United Launch Alliance’s Vulcan Centaur rocket. The spaceplane is scheduled for the rocket’s second mission, although Vulcan is yet to fly for the first time due to several delays. The spaceplane is tentatively slated for an April launch, but that still depends on the rocket’s first test flight.

In the future, Sierra Space also wants to launch crewed Dream Chaser missions to its own space station, as opposed to the Orbital Reef space station, which it is designing in collaboration with Jeff Bezos’ Blue Origin—a relationship that appears to be in doubt.

Early next month, SpaceX will send a clutch of science experiments to the space station investigating a range of topics, from high-speed laser communications to rolling atmospheric waves on Earth.

A SpaceX Falcon 9 rocket, carrying the uncrewed Dragon spacecraft, is scheduled to launch toward the International Space Station (ISS) no earlier than Nov. 5, kicking off the CRS-29 cargo mission. Launch coverage will be available here at Space.com, via NASA Television.

“All of the science really supports the initiatives of NASA, as well as the ISS program, in supporting innovative research, being able to improve science capabilities on the International Space Station, and for future commercial and exploration programs,” said Meghan Everett, deputy program scientist for the ISS program at NASA’s Johnson Space Center in Houston, during a telephone press conference on Thursday (Oct. 26).

An example is the laser experiment, called ILLUMA-T (“Integrated LCRD Low-Earth-Orbit User Modem and Amplifier Terminal”), which aims to boost ISS communications while assisting future missions in deep space. ILLUMA-T is the remaining hardware item needed to transmit data through the agency’s Laser Communications Relay Demonstration (LCRD) satellite that launched in 2021. When the system is ready, the satellite will relay the information to optical ground stations in Hawaii and California.

“Future missions have potentially exceptionally large data needs, and so we have to think about how we’re going to meet those needs,” NASA’s Jason Mitchell said during the same press conference. “We all understand that more data means more discoveries,” added Mitchell, the director for the advanced communications and navigation technologies division at NASA’s space communication and navigation program. (That program is funding ILLUMA-T.)

NASA is looking to beef up its communications capabilities beyond those provided by the radio spectrum, which the agency has mostly been using for missions in the past 65 years. While the experiment is not the first laser demonstration in space, it will be the first two-way laser communications relay, agency officials have stated.

The system will use infrared light to transmit videos and images faster. NASA is counting on this technology to help amp up science returns over long distances, particularly at the moon and Mars, where the agency has plans for new human and robotic missions. 

“One of our big goals in this demonstration is to demonstrate the pointing of that laser system … from the ISS, as it’s traveling in its orbit,” Glenn Jackson, acting project manager for ILLUMA-T at NASA’s Goddard Space Flight Center near Baltimore, said in the phone call.

Given that the ISS is traveling around our planet at roughly 18,000 mph (29,000 kph), that’s no small feat. Even small Earth lasers encounter pointing issues, which may be exacerbated in space, Jackson said. An example he cited: “If you have a laser pointer and you’re trying to point that laser to a whiteboard or to your chalkboard in your classroom, sometimes you see that laser bouncing around a bit.”

The ILLUMA-T system is smaller and less massive than radio gear, which allows more room for other science payloads or fuel on future missions. Less power use also provides more resources for science instruments drawing on the spacecraft’s battery.

Other benefits include fewer issues in getting the required spectrum for launch – unlike radio, the optical spectrum is not as highly regulated, and getting a license is easier, Mitchell pointed out. 

The hope is to reduce the risk and to bring laser communications to users across the solar system as the technology matures. For example, NASA’s Artemis 2 crew that will circle the moon in 2024 plans to debut its own optical communications system “to understand what operational needs are for that [lasers] from a lunar perspective,” Mitchell said.

Numerous partners are involved in the experiment. It is managed by NASA Goddard in partnership with two entities: NASA Johnson and the Massachusetts Institute of Technology (MIT) Lincoln Laboratory in Lexington, Massachusetts. 

Select other experiments going up on CRS-29 include (in NASA’s words):

• NASA’s Atmospheric Waves Experiment (AWE). It uses an infrared imaging instrument to measure the characteristics, distribution, and movement of atmospheric gravity waves. These waves roll through Earth’s atmosphere when air is disturbed, and play a role in defining the climate. 
• Aquamembrane-3, an investigation from the European Space Agency (ESA). It continues evaluation of replacing the multi-filtration beds used for water recovery on the space station with a type of membrane known as an Aquaporin Inside Membrane.
• Gaucho Lung, sponsored by the ISS National Lab. It studies how mucus lining the respiratory system affects delivery of drugs carried in a small amount of injected liquid, known as a liquid plug. 
• Rodent Research-20. “That study is designed to look at reproductive health in female mice,” Everett said in the press conference. “We will look at the function of the ovaries during flight, and after flight … that will give us indication of the effects of microgravity on reproductive function. (It will) hopefully improve some of our knowledge of reproductive health here on the ground.” The research uses hardware developed by NASA’s Ames Research Center to safely house the animals. 

Hundreds of Roman Empire forts popped up in old spy satellite imagery depicting regions of Syria, Iraq and nearby “fertile crescent” territories of the eastern Mediterranean.

These satellites were once used for reconnaissance in the 1960s and 1970s, but their data is now declassified. Some of their archived images are now allowing for fresh archaeology finds in Earth zones often difficult for researchers to visit.

The newly found 396 forts, spotted straight from space, confirm and extend an aerial survey of the region performed in 1934; this survey had recorded 116 forts on the Roman Empire’s eastern frontier. Archaeologists continue to agree with the basic conclusion of that nearly century-old study, which is that Rome was fortifying its frontier — and the new study brings fresh perspective.

“These forts are similar in form to many Roman forts from elsewhere in Europe and North Africa. There are many more forts in our study than elsewhere, but this may be because they are better preserved and easier to recognize,” lead author Jesse Casana, a professor of anthropology focusing on the Middle East at New Hampshire’s Dartmouth College, told Space.com in an email interview. “However, it could also have been a real product of intensive fort construction, especially during the second and third centuries AD.”

The origins of Roman Empire forts 

Most historians say the Roman Empire began around 27 BCE. The older Republic had been in the throes of a lengthy civil war after a group of senators assassinated the dictator Julius Caesar in 44 BCE, alleging Caesar had grown too powerful. 

Eventually, the Senate backed one of the rivals for Rome’s leadership — Octavian, Caesar’s heir — and gave the young man temporary dictatorship powers, as well as military backing. Very simply put, this resulted in Octavian overcoming his rivals. In 27 BCE, he received one-man leadership powers permanently from the Senate. Now called Augustus (“the exalted one”), his stated aim was to “restore the Republic” while consolidating his powers for himself and his successors.

The line of “imperators” (emperors) continued after Augustus for centuries. But during the period when the study’s newly found Roman forts were constructed – roughly spanning the second and sixth centuries CE, though other times are likely included – various difficulties were arising. Particularly in the third and fourth centuries, for example, there was no established line of emperor succession, leading to repeated assassinations and coups. 

The huge Roman Empire, stretching at its largest from Britain to Egypt, was also struggling to maintain its borders, in part due to sheer size and in part due to incursions from nomadic groups grappling with climate change. Following a few reorganizations, the Roman Empire was officially divided between two heirs in 395 CE, after the death of Emperor Theodosius I. The western side was gradually taken over by other peoples, while the eastern side persisted in what we now call the Byzantine Empire down to roughly the 1400s CE.

That brings in how the newly found forts’ functioned at the empire’s edge. 

In a 1934 study based on flights performed in the 1920s, pioneering French archaeologist Antoine Poidebard found 116 forts in an aerial survey, the study authors stated. He suggested the fortifications were supposed to be a defensive line against Persians (more properly, the Parthians and the Sasanians, who were other superpowers of the era). But a limitation of his work is that he mainly flew his plane where he believed forts would be found. The forts, to be fair, were surveyed before the existence of modern-day archaeological standards. 

Casana and fellow researchers’ new satellite image study was, on the other hand, able to cover more ground and counteracted Poidebard study’s bias. It showed the freshly discovered 396 forts had no discernible defensive north-south pattern against eastern peoples, and were instead scattered.

The new results may confirm the suspicions of some earlier scholars, who argued the 116 Poidebard forts were too far apart to form a connective line of defenses. Instead, the encampments in modern-day Syria and Iraq were possibly used to protect caravans bringing valuable goods to and from Rome’s provinces, while allowing for communications and intercultural exchanges. 

The story of the satellites

The study images came via two satellite programs originally used for surveillance during the Cold War between the United States and the Soviet Union (and their respective allies). The nations pursued military technologies (including early space missions) on “political, economic, and propaganda fronts” with minimal use of weapons, according to Encyclopedia Britannica. 

During this time, the “Space Race” was also in full-force,  seeing both space powers rapidly accrue milestones with human and robotic space missions, such as launching the first people and sending spacecraft around the solar system. (The rivalry sometimes coalesced into moments of collaboration, however, such as the Apollo-Soyuz Test Project space mission that launched astronauts and cosmonauts together in 1975.)

One of the aims of the Cold War was rapid military reconnaissance using satellites that could promptly return photographic images to Earth. The Central Intelligence Agency’s Corona program, with assistance from the U.S. Air Force, imaged areas in nations such as China and the Soviet Union between 1959 and 1972. A successor program called Hexagon (also called Big Bird, KH-9 or KeyHole-9) continued surveying Soviet military zones between 1971 and 1986, led by the National Reconnaissance Office.

But most importantly for the new study, these satellites were specifically built to take clear and precise images.

“Because these images preserve a high-resolution, stereo perspective on a landscape that has been severely impacted by modern-day land-use changes, including urban expansion, agricultural intensification and reservoir construction, they constitute a unique resource for archaeological research,” the study authors stated in their work, published Thursday (Oct. 25) in Antiquity.

And it was actually the images’ declassification that offers such rich data harvesting grounds for archaeologists, Casana told Space.com, as the pictures are easy to source and relatively inexpensive. 

“All the satellite images we used in this study are publicly available through the U.S. Geological Survey, who serve them on their EarthExplorer data distribution portal,” he explained. “Images that are already scanned can be downloaded there for free, while unscanned images can be purchased for $30 USD.”

After downloading the images, however, came hours of processing to georeference and spatially correct the images. These processes are needed to accurately map features on the Earth’s surface using GPS technology, which itself was originally used for the military as well. Archaeologists have reshared most of their work with the community via the Corona Atlas Project led by the University of Arkansas’ Center for Advanced Spatial Technologies. The site even includes “a basic archaeological site database for the Middle East to help locate sites of interest,” Casana said.

Aside from continuing the work of Poidebard, who was cited as influential to “a long history of scholarship” in the new study, the declassified Corona and Hexagon imagery provide other benefits to archaeologists. Ancient sites are subject to many threats, Casana pointed out. The public and media focus on the damage caused by looting and the military, but archaeologists find that “destruction of sites by urban development, agricultural intensification, and dam construction are far more widespread and severe,” he said. (Climate change has a role to play in these problems, too, as communities seek to protect food and water resources against a warming planet.)

“The real value in historical, high-resolution imagery like Corona and Hexagon is in preserving a picture of a landscape that by and large no longer exists,” Casana said, noting the spy imagery is roughly half a century old and there has been a lot of change in Iraq and Syria since then. “Our study also helps show that an unknown number of other sites were also likely lost in the time between Poidebard’s flights in the 1920s and the Corona imagery of the late 1960s,” he added.

More broadly, the study may also add nuance to how the Romans managed their empire frontiers. Ancient Romans were famously militaristic and well-known for incursions reaching areas as far as Britain; they sometimes even fought with or allied with local tribes depending on the local commander’s (or emperor’s) purpose. At the same time, however, the Romans depended on trade and valued it. The researchers say their new fort study may help provide more fodder for the Roman empire’s interregional links.

But the new study might be subject to preservation bias, the authors warn. The density of forts seen in some areas – as well as the distribution of those forts that remain visible after all the eons – may reflect the reality that many others were lost due to “settlement and land-use practices,” the authors stated. And the ground continues to change rapidly; many forts Poidebard spotted were no longer visible just a generation later, in the spy satellite images. 

That said, the archaeologists have found an additional 106 “fort-like features” in a subregion of the satellite study, in which future discoveries may lurk. “We are planning to expand the survey to prospect for more sites, including forts and others,” Casana said. “We will work within our current survey area using additional forms of imagery, such as the more recently declassified Hexagon and U2 spy plane imagery, as well as expanding regionally into other parts of the Middle East.”
