The Colors of Saturn from Cassini

 

What creates Saturn's colors? The featured picture of Saturn only slightly exaggerates what a human would see if hovering close to the giant ringed world. The image was taken in 2005 by the robot Cassini spacecraft that orbited Saturn from 2004 to 2017. Here Saturn's majestic rings appear directly only as a curved line, appearing brown, in part from its infrared glow. The rings best show their complex structure in the dark shadows they create across the upper part of the planet. The northern hemisphere of Saturn can appear partly blue for the same reason that Earth's skies can appear blue molecules in the cloudless portions of both planet's atmospheres are better at scattering blue light than red. When looking deep into Saturn's clouds, however, the natural gold hue of Saturn's clouds becomes dominant. It is not known why southern Saturn does not show the same blue hue one hypothesis holds that clouds are higher there. It is also not known why some of Saturn's clouds are colored gold.

NASA faces $80,000 claim after space debris hit family home

JUNE 22, 2024

 

An American family is claiming more than $80,000 from NASA after a small piece of debris fell from space and smashed through the roof of their Florida home, a law firm said Friday.

The problem of space trash has risen in tandem with increased spatial traffic, and NASA's response could set a precedent for how future claims are handled, law firm Cranfill Sumner said in a statement.

On March 8, an object weighing just 700 grams hit Alejandro Otero's home in Naples, Florida, making a hole in the roof.

 

NASA later confirmed it was part of a cargo pallet of used batteries that was released from the International Space Station as waste in 2021.

Instead of fully disintegrating before falling to Earth, a section remained intact when it reentered the atmosphere, the US space agency said.

Otero's son was at the house at the moment of impact, according to the law firm, which said that NASA has six months to respond to its claim.

 

"My clients are seeking adequate compensation to account for the stress and impact that this event had on their lives," said lawyer Mica Nguyen Worthy.

"They are grateful that no one sustained physical injuries from this incident, but a 'near miss' situation such as this could have been catastrophic.

"There could have been serious injury or a fatality."

 

NASA did not immediately respond to AFP's request for a comment.

China launches Sino-French astrophysics satellite, debris falls over populated area

June 22, 2024

 

A Chinese launch of the joint Sino-French SVOM mission to study Gamma-ray bursts early Saturday saw toxic rocket debris fall over a populated area.

A Long March 2C rocket lifted off from Xichang Satellite Launch Center at 3:00 a.m. Eastern (0700 UTC) June 22, sending the Space Variable Objects Monitor (SVOM) mission satellite into orbit.

The launch was declared successful by the China Aerospace Science and Technology Corporation (CASC) a short time after liftoff.

 

Gamma-ray bursts (GRBs) are violent electromagnetic explosions which can release as much energy in a few seconds as the Sun will emit over its entire 10-billion-year lifetime.

SVOM is a collaboration between the China National Space Administration (CNSA) and France’s Centre national d’études spatiales (CNES).

The mission will look for high-energy electromagnetic radiation from these events in the X-ray and gamma-ray ranges using two French and two Chinese-developed science payloads.

These include the Microchannel X-ray Telescope (MXT), a narrow-field-optimized lobster eye X-ray focusing telescope.

 

Studying GRBs, thought to be caused by the death of massive stars or collisions between stars, could provide answers to key questions in astrophysics.

This includes the death of stars and the creation of black holes. However the launch of SVOM also created an explosion of its own closer to home.

A video posted on Chinese social media site Sina Weibo appears to show a rocket booster falling on a populated area with people running for cover.

The booster fell to Earth near Guiding County, Qiandongnan Prefecture in Guizhou province, according to another post.

An airspace closure notice for the mission established a temporary danger area containing Guiding County, Guizhou.

 

A number of comments on the video noted the danger posed by the hypergolic propellant from the Long March rocket.

Some comments on the post suggested the event was related to a failed recovery of SpaceX’s Starship, while another suggested an American conspiracy.

The Long March 2C uses a toxic, hypergolic mix of nitrogen tetroxide and unsymmetrical dimethylhydrazine (UDMH).

Reddish-brown gas or smoke from the booster could be indicative of nitrogen tetroxide, while a yellowish gas could be caused by hydrazine fuel mixing with air.

Contact with either remaining fuel or oxidizer from the rocket stage could be very harmful to individuals.

 

Falling rocket debris is a common issue with China’s launches from its three inland launch sites.

China’s first three launch sites were established during the Cold War. Sites deep inland were thus selected to provide a measure of protection amid tensions with the U.S. and Soviet Union.

Authorities are understood to issue warnings and evacuation notices for areas calculated to be at risk from launch debris, reducing the risk of injuries.

The launch of SVOM was China’s 29th launch of the year. CASC stated China is aiming to launch around 100 times across 2024, including around 30 commercial missions.

‘It moved like a flash from our 10 o’clock high position to 3 o’clock.’ US Navy F-14 pilot recalls odd UFO sightings he had while flying the mighty Tomcat

Jun 23 2024

 

Ever wonder what kinds of unusual objects pilots see from the air?

With a truly unique vantage point, they’ve reported a range of strange sightings, including geoglyphs, drones and… UFOs.

Sightings of unidentified flying objects (UFOs) or unidentified anomalous phenomena (UAP) have been reported throughout history.

Given the potential security and safety risks they pose, as well as scientific curiosity, there is increasing interest in understanding what these sighting reports represent.

 

Pilots have claimed to see UFOs for decades – sightings usually involve objects flying in a formation or bright lights, as Doyle Borchers, former US Navy F-14 Tomcat test pilot, recalls on Quora;

‘Once as an F-14 test pilot flying a night mission returning from White Sands range in New Mexico to NAS Pt Mugu. The weather was bad in Mugu so we were diverted to NAS Miramar in San Diego.

We were at 24,000 ft and both my Radar Officer and I saw a string of lights well below us on what we thought was the desert floor, but the continued to follow us at almost 500kts.

As we turned, the lights followed us, and finally after about 10 minutes broke off and departed. I wanted to make a report, but my RIO wouldn’t back me up.’

 

He continues; ‘Second one was when I was flying and F-14 from Palma/Majorca to RNAS Yeovilton for an airshow back in 1976. Both my RIO and I saw a bright silver disk well above our altitude of 35,000ft. I would guess it was at about 70,000ft. It moved very quickly from our 10 o’clock high position to 3 o’clock, and I mean like a flash, and then was out of sight.’

Borchers concludes; No doubt in my mind that UFO’s are real.’

UFOs over the skies of Taiwan

Sun, Jun 23, 2024

 

Before Tsai’s announcement, Taiwan’s earliest UFO photo was believed to be taken by then-high schooler Chih Chung-chieh (池仲傑) in 1973.

However, UFO enthusiasts, including the elder Tsai, have long questioned the authenticity of Chih’s photo due to a number of discrepancies.

During the press conference, former TUFOS president Ho Hsien-jung (何顯榮) noted that while 95 percent of reported UFO sightings can be explained as natural or human-made phenomena, he felt confident enough to announce Tsai’s photo as “Taiwan’s first UFO photo.”

The United Daily News did report a “strange object flying around in the sky” the same day Tsai claimed to have snapped the photo, describing a pale red, cigar-shaped object that emitted bright light.

 

The Taipei City Observatory told the paper that it first appeared around 8:25pm for about 90 seconds before reemerging roughly an hour later.

Several citizens also saw it and called the observatory, which was unable to explain the phenomenon.

The Central Weather Bureau quickly clarified that the “strange object” was a weather balloon they released — although Ho maintains that they were two different objects and that the bureau was trying to cover up the event for the authorities.

Tsai Chang-hsien told reporters that it was unlikely to be a balloon, and although he wouldn’t call it an alien spacecraft, it was certainly an “unidentified flying object.”

 

UFO PIONEERS

While ancient Chinese texts contain numerous events that could be interpreted as UFO sightings, Ho writes in the 2004 book, Tracking UFO Sightings (UFO目擊大追蹤), that no references were found in Taiwan until the modern era.

In fact, the study of UFOs was largely unknown in Taiwan until Lu Ying-chung (呂應鐘) began translating Western UFO books in the mid-1970s.

Reports show that Lu, often called the “godfather of Taiwan UFO studies,” coined the commonly used Mandarin term (you-fu, 幽浮) for UFO.

Of course, people had an idea of what an extraterrestrial spacecraft “should” look like, as cartoonist Liu Hsing-chin (劉興欽, see “Taiwan in Time: The inventive comic artist,” April 9, 2023) published Robots Battle Flying Saucers (機器人戰飛碟) in 1968.

 

Both Ho and Lu attribute the earliest credible UFO sightings in Taiwan to Tsai Chang-hsien, who headed the Taipei City Observatory from its inception in 1958 to 1991.

Tsai became the first Taiwanese to have an asteroid named after him in 1978. Between 1956 and 1959, Tsai witnessed mysterious light bodies glide through the sky three times, and although he was reluctant to call them UFOs, he found it difficult to explain their presences.

Tsai writes in The Journal of UFO Research (飛碟探索) that he received dozens of calls about flying saucers during his tenure at the observatory.

Most of them were explainable, some were falsifications. He only deemed two cases “unidentifiable” — one in 1974 and one in 1979.

 

“As of now, those who believe in flying saucers can continue believing in them, and those who don’t are free to do so as well,” Tsai writes.

“Too many people say that they’ve seen a flying saucer, met an extraterrestrial or that there are already many aliens living among us, but none of these claims have been scientifically proven.”

Tsai writes that extraterrestrial life surely exists somewhere in the universe, but the chances of humans encountering them are quite minuscule.

By contrast, Lu not only believes that aliens have played a crucial role in human development, he told the Liberty Times in 2010 that he and countless others are human reincarnations of extraterrestrials.

CLOSE ENCOUNTERS?

According to the 1996 Liberty Times report, a teenaged Tsai Chang-hung was hanging out at the observatory looking at stars when he saw a bright dot make an abrupt 90 degree turn near the Big Dipper.

He grabbed his 16mm camera and called his brother to come look, but the dot had disappeared. Tsai waited for a while alone, and as soon as it reappeared, he snapped three photos.

The object hovered above Guanyin Mountain (觀音山) in New Taipei City for about 30 seconds before disappearing.

 

The developed photos only captured about two-thirds of the object and were of poor quality, and Tsai didn’t know what a UFO was back then, so he says he never told his brother and soon forgot about it.

He still kept all his film, enabling the brothers to later redevelop the photo and digitally enhance it to show the object clearly in 1996. The Central Daily News and United Daily News also picked up this story.

Another oft-cited account is from 1983, when a student from Taoyuan’s Touchou Elementary School (頭洲國小) heard a loud explosion in the middle of the sports field.

 

He found a 30cm long humanoid and took it to his teachers, who observed a specimen of it under a microscope and were unable to find any cells or organic matter.

He later took it home, and despite his parents urging him to get rid of it, his elder brother Wen Wen-hsing (溫文星) dissected it to find just tubes and gooey matter underneath. They later buried the “being.”

Thirty years later, Wen made an appearance at a UFO exhibition in Taipei and retold his account to reporters. The Liberty Times ran it on June 23, 2013 under the headline “I dissected an alien’ — witness tells his story in person.”

 

ALIEN CRAZE

In September 1995, Chinese Television System (華視) showed the British documentary Alien Autopsy, which was later proven to have been a hoax. Nevertheless, coupled with the popularity of the X-Files, UFO sightings increased dramatically in Taiwan afterwards.

Ho’s chronology records seven instances in 1996 alone. On March 10, 1996, a China Airlines plane narrowly avoided a collision with a flat and round object over the ocean while preparing to land at Taoyuan Airport. After successfully landing, the pilot jokingly told reporters, “Maybe it’s a UFO.”

As the incident happened during a tense period of the Third Taiwan Strait Crisis, authorities did not rule out the possibility of it being a Chinese warplane.

The book lists more than 50 alleged UFO sightings in Taiwan from 1954 to 2003, and reports have continued to make the news over the decades — although they’re usually light-hearted pieces that are debunked at the end of the articles.
