The Acid Test of 3I/ATLAS at Perihelion

October 28, 2025

 

On October 29, 2025, the interstellar object 3I/ATLAS will get to the closest distance of 203 million kilometers from the Sun, completing half of its journey through the Solar System.

This would constitute half of the journey as long as nothing dramatic happens to it at that time.

 

For a spacecraft, perihelion is the optimal time for either acceleration or deceleration by an impulse from an engine, thanks to the gravitational assist from the Sun.

This is also true of a mothership releasing mini-probes that maneuver towards the planets. Unfortunately, we cannot observe 3I/ATLAS from Earth at this opportune time, which raises the question of whether its trajectory was fine-tuned by extraterrestrial intelligence?

 

As I explained today to Bill Hemmer and Dana Perino in America’s Newsroom on Fox News (accessible here), the fundamental question is whether 3I/ATLAS is a Trojan Horse with the external appearance of a natural comet but carrying a potential threat in its interior.

The city of Troy would have been better served if its guardians had not been fooled by the external appearance of the Trojan Horse. For that reason, I co-authored with Omer Eldadi and Gershon Tenenbaum a White Paper (accessible here), which encouraged policy makers to take seriously the potential threat from a black swan event involving an unusually massive object moving along the ecliptic plane like 3I/ATLAS.

 

Perihelion is just 2 days before Halloween. Is 3I/ATLAS wearing a costume of a comet or is it a truly icy rock of natural origin?

 

On November 3, 2025, 3I/ATLAS will come within a distance of 97 million kilometers from Venus. During the same week, it will be observable to the ESA mission, Juice, along its path to Jupiter.

On December 19, 2025, 6 days before Christmas, 3I/ATLAS will get to its closest distance of 267 million kilometers from Earth, assuming a purely gravitational trajectory. Will 3I/ATLAS send mini-probes towards Earth as Christmas gifts to humanity?

I had asked my research team in the Galileo Project to check if there is any unusual activity by anomalous objects in the Earth’s atmosphere based on data collected by the three Galileo Observatories in the coming months.

On March 16, 2026, 3I/ATLAS will arrive at its closest distance of 54 million kilometers from Jupiter, where the Juno spacecraft could image it and use a radio antenna to check for any radio transmission as a technological signature.

 

Thus, perihelion constitutes the acid test of 3I/ATLAS. If it is a natural comet glued together by weak forces, its heating by 770 watts per square meter may break it up into fragments which evaporate more quickly as a result of their large surface area per unit mass.

The resulting fireworks might generate a much brighter cometary plume of gas and dust around it. However, if 3I/ATLAS was technologically manufactured — as suggested by its high abundance of nickel relative to iron, it might maneuver or release mini-probes.

Other technological signatures include artificial lights or excess heat from an engine. We will know the nature of 3I/ATLAS better in the coming months.

 

Also today, my Joe Rogan Experience was publicly released here. This 2.25-hour episode covered 3I/ATLAS, the search for alien technologies and the Galileo Project in search for Unidentified Anomalous Phenomena.

I emphasized the need for cosmic modesty as we examine who else lives in our cosmic neighborhood and the potential threat from alien technology.

On a blind date of interstellar proportions, we better observe our dating partners rather than be guided by the limited imagination of our fellow script writers in Hollywood.

 

Here’s hoping that we will be wise enough to learn something new and not be trapped in traditional echo chambers.

https://news.lockheedmartin.com/2025-10-28-X-59-Soars-A-New-Era-in-Supersonic-Flight-Begins

 

'Son of Concorde' takes flight! NASA's 100-foot, $247million supersonic jet that can travel from London to New York in under 4 hours takes to the skies for the first time

Updated: 10:06 EDT, 29 October 2025

 

After nearly a decade in development, NASA's supersonic jet dubbed 'Son of Concorde' has successfully completed its first test flight.

The 100-foot, $247million plane, built by Lockheed Martin for NASA, took off from Palmdale Regional Airport in California at about 10:15 EDT on Tuesday.

After about an hour performing oval-shaped loops, the plane landed safely at NASA's Armstrong Flight Research Center 25 miles further northeast.

Its peak altitude during the flight was 12,000 feet (3,660 meters) – which is under half that of a commercial plane at cruising altitude – but experts hope it will be able to reach 55,000 feet (16,800 metres).

 

Officially known as X-59, the manned aircraft is designed to pave the way for faster air travel at 'supersonic' speeds of up to 925mph.

At such as speed, it could transport paying passengers from London to New York in under four hours – revolutionizing the industry and freeing up time for busy businesspeople and holidaymakers.

'We are thrilled to achieve the first flight of the X-59,' said OJ Sanchez, vice president and general manager of Lockheed Martin's Skunk Works division.

'This aircraft is a testament to the innovation and expertise of our joint team, and we are proud to be at the forefront of quiet supersonic technology development.'

 

According to Lockheed Martin, X-59 performed 'exactly as planned' prior to its safe landing at NASA's Armstrong Flight Research Center.

However, the single-engine jet only reached speeds of 230mph, which is nowhere near its top speed of 925mph – much faster than the speed of sound (767mph).

Further test flights in the coming months will 'expand the X-59's flight envelope' and get closer to the plane's top flying speed, the aerospace company said.

Despite being short of the all-important speed threshold, experts hailed this latest milestone as 'a new era in supersonic flight'.

 

Sean Duffy, Secretary of the Department of Transportation and acting NASA administrator, called the experimental plane 'a symbol of American ingenuity'.

He said: 'The American spirit knows no bounds. It's part of our DNA – the desire to go farther, faster, and even quieter than anyone has ever gone before.

'This work sustains America's place as the leader in aviation and has the potential to change the way the public flies.'

X-59 is dubbed 'Son of Concorde' because it would be the first passenger plane to fly at supersonic speeds (faster than the speed of sound) since the days of the retired Anglo-French liner over 20 years ago.

One of the issues with Concorde that led to its retirement in 2003 was the 'sonic booms' it emitted as it flew.

Described as sounding somewhere between a thunderclap and an explosion, sonic booms happen when shock waves from an object travelling through the air faster than the speed of sound merge together before they reach the ground.

Concorde's sonic booms were often described as unsettling by members of the public on the ground below, which meant Concorde never replaced slower, more conventional aircraft.

In contrast, X-59’s thin, tapered nose accounts for almost a third of its length and breaks up the shock waves that usually result in a sonic boom, instead producing a quieter 'thump'.

 

Due to X-59's odd configuration, the cockpit is located almost halfway down the length of the aircraft – and the craft does not have a forward-facing window.

Instead, it's fitted with the 'eXternal Vision System', a series of high-resolution cameras feeding a 4K monitor in the cockpit.

Eventually, NASA – which will be the primary user – will fly the aircraft over cities across the US, which are yet to be selected.

It will collect feedback about the sound the X-59 generates and how people perceive it before providing the data to the Federal Aviation Administration.

 

NASA stresses that X-59 is one of its experimental crafts and is not a commercial airliner designed to carry passengers

However, if supersonic flight proves to be feasible, bulkier next-gen versions fitted out with passenger seats could transport paying passengers just like Concorde did.

For 50 years, the US prohibited supersonic flights because of disturbance caused by sonic booms to communities below, which was why Concorde was largely restricted to flights over the Atlantic – namely Paris to New York and London to New York.

The legendary plane was the world’s first supersonic airliner and operated for 27 years, but it was grounded in October 2003 largely due to high fuel costs, concern over its noise and a preference for lower fares over speed.

 

Ever since, no government or manufacturer has since been able to build a commercial plane that can travel faster than the speed of sound – although Lockheed Martin is not the only one trying.

Another American company called Boom Supersonic is working on its own supersonic craft, called Overture, which is eyeing commercial passenger flights in 2029.

Meanwhile, China is working on its own experimental supersonic plane, called Yunxing, which could go at three times that of X-59.

Engineers achieve incredible potential with groundbreaking aircraft in NASA partnership: 'Flyover traffic'

Tue, October 28, 2025 at 4:50 PM PDT

 

Researchers are working with NASA to find a clean and quiet answer to gridlock.

CBS News reported on a new research lab at the Georgia Institute of Technology that is working to make airplanes electric, with a big goal to innovate an aircraft that is battery-powered and quiet, able to fly over a city like a helicopter but without the air or noise pollution.

 

This is one of the first major projects of RAVEN and is a joint effort with NASA, looking to create a functioning aircraft in the 1,000-pound weight class with vertical takeoff and landing capabilities.

"This is an airplane that we are converting into an electric aircraft in a major partnership with NASA, so you might be able to fly from Midtown Atlanta down to the airport — fly over traffic, similar to a helicopter," said Brian German, an aerospace engineering professor at Georgia Tech.

 

According to German, helicopters are difficult to utilize for daily travel because of their noise. He is hopeful that new, quiet propulsion systems can make this type of aircraft viable in cities.

The research team is also hopeful that this innovation could eventually replace business jets for short trips between cities, curbing air pollution and contributing less to rising global temperatures.

 

Developments in electric aircraft are building on innovations with electric vehicles on land, with major implications for savings on maintenance and fuel, cleaner air, and a healthier planet.

If you are driving or considering driving an electric vehicle while electric aircraft are still a work in progress, you can save money by charging your car at home.

 

Qmerit is helping interested homeowners install Level 2 EV chargers with free, instant installation estimates.

Renewable energy options such as home solar can further enhance savings and benefits, and EnergySage makes it easy to bring clean energy into your own home.

Men experience greater eye changes from spaceflight, while brain differences between sexes are subtle

October 29, 2025

 

A new study into how spaceflight impacts the human brain and eyes revealed notable sex differences in brain fluid shifts, with female astronauts showing a greater reduction in fluid around the uppermost part of the brain than their male counterparts.

Led by Rachael D. Seidler, Ph.D., director of the University of Florida’s Astraeus Space Institute and professor of applied physiology and kinesiology, the study analyzed data from astronauts to determine how factors such as sex, age and body metrics relate to structural brain and eye changes after space travel.

The findings, published in August in npj Microgravity, provide key information for protecting astronaut health on long-duration missions to the moon and Mars.

 

This is one of the first studies to look at sex differences in the physiological response to spaceflight.

“The data on sex differences in response to spaceflight are scant, given the historically low number of female astronauts,” Seidler said. “Our dataset was still only approximately one-quarter females, but since the overall dataset was fairly large we were able to examine sex differences.”

In addition to changes in fluid around the brain, the team also found that a form of eye compression, a hallmark of Spaceflight Associated Neuro-ocular Syndrome known as globe flattening, was the most consistent eye change among crew members.

 

“By far the most prevalent sign of eye changes that we observed was globe flattening, suggesting that this should be the primary monitoring target for ocular health,” Seidler said. “Interestingly, eye changes were more prevalent in males than females.”

Globe flattening, when the back of the eyeball becomes slightly indented or pushed inward, might sound minor, but it can have significant effects on vision and raise concerns for long-duration space missions.

Surprisingly, there was no strong link between brain structural changes and eye changes, suggesting that the effects on the eyes and brain may arise from distinct mechanisms rather than shared physiological causes.

 

The research underscores UF’s growing leadership in space health science. Through the Astraeus Space Institute, Seidler leads multidisciplinary collaborations that connect neuroscience, physiology and space research to advance human performance and safety in spaceflight.

“We used UF's HiPerGator computing cluster for our analyses in this study, enabling us to analyze our data at high speeds,” Seidler said.
