SR-71 Pilot David Peters said that he DID look out the windows in fact, it’s part of piloting a plane to be aware of your surroundings.

Myth busting .

It is a myth that SR pilots didn’t have time to look out the window . This Picture is somewhat what they would see. It’s gorgeous up there.

SR 71 pilot David Peters wrote “Makes me think of one of the mind games we got into.”

Doing the Korean DMZ out of Kadena on a moonless clear night we could see 3.5 trillion more stars at 80,000 feet than you can on the ground. That’s according to Palomar Mountain Observatory in California. We would come in off the Sea of Japan and there are almost no lights.

The Japanese fishing fleet is working around that area most of the time and they just have lanterns hung on the boats.

When you make the inbound turn what you see above you is very much like this picture. What you see below is much more like what you see from the ground looking at the sky.

It will mess up you head really quick and you jump on instruments just like you were flying in weather. ( he would see lights in the ocean, where there is no electricity.)

Edwin Hubble Discovers the Universe - February 17th, 1996.

"No person in history has had greater impact in determining the extent of our Universe than Edwin Hubble. From proving that other galaxies existed, to proving that galaxies move apart from one another, Hubble's work defined our place in the cosmos. Hubble lived from 1889 to 1953 and is shown above, posing with the 48-inch telescope on Palomar Mountain and his famous pipe. In memory of his great work, the Orbiting Space Telescope was named after him."

NASA’s swift studies gas-churning monster black holes

Scientists using observations from NASA’s Neil Gehrels Swift Observatory have discovered, for the first time, the signal from a pair of monster black holes disrupting a cloud of gas in the center of a galaxy.

“It’s a very weird event, called AT 2021hdr, that keeps recurring every few months,” said Lorena Hernández-García, an astrophysicist at the Millennium Institute of Astrophysics, the Millennium Nucleus on Transversal Research and Technology to Explore Supermassive Black Holes, and University of Valparaíso in Chile. “We think that a gas cloud engulfed the black holes. As they orbit each other, the black holes interact with the cloud, perturbing and consuming its gas. This produces an oscillating pattern in the light from the system.”  

A paper about AT 2021hdr, led by Hernández-García, was published Nov. 13 in the journal Astronomy and Astrophysics.

The dual black holes are in the center of a galaxy called 2MASX J21240027+3409114, located 1 billion light-years away in the northern constellation Cygnus. The pair are about 16 billion miles (26 billion kilometers) apart, close enough that light only takes a day to travel between them. Together they contain 40 million times the Sun’s mass.

Scientists estimate the black holes complete an orbit every 130 days and will collide and merge in approximately 70,000 years.

AT 2021hdr was first spotted in March 2021 by the Caltech-led ZTF (Zwicky Transient Facility) at the Palomar Observatory in California. It was flagged as a potentially interesting source by ALeRCE (Automatic Learning for the Rapid Classification of Events). This multidisciplinary team combines artificial intelligence tools with human expertise to report events in the night sky to the astronomical community using the mountains of data collected by survey programs like ZTF.

“Although this flare was originally thought to be a supernova, outbursts in 2022 made us think of other explanations,” said co-author Alejandra Muñoz-Arancibia, an ALeRCE team member and astrophysicist at the Millennium Institute of Astrophysics and the Center for Mathematical Modeling at the University of Chile. “Each subsequent event has helped us refine our model of what’s going on in the system.”

Since the first flare, ZTF has detected outbursts from AT 2021hdr every 60 to 90 days.    

Hernández-García and her team have been observing the source with Swift since November 2022. Swift helped them determine that the binary produces oscillations in ultraviolet and X-ray light on the same time scales as ZTF sees them in the visible range.

The researchers conducted a Goldilocks-type elimination of different models to explain what they saw in the data.

Initially, they thought the signal could be the byproduct of normal activity in the galactic center. Then they considered whether a tidal disruption event — the destruction of a star that wandered too close to one of the black holes — could be the cause.

Finally, they settled on another possibility, the tidal disruption of a gas cloud, one that was bigger than the binary itself. When the cloud encountered the black holes, gravity ripped it apart, forming filaments around the pair, and friction started to heat it. The gas got particularly dense and hot close to the black holes. As the binary orbits, the complex interplay of forces ejects some of the gas from the system on each rotation. These interactions produce the fluctuating light Swift and ZTF observe.

Hernández-García and her team plan to continue observations of AT 2021hdr to better understand the system and improve their models. They’re also interested in studying its home galaxy, which is currently merging with another one nearby — an event first reported in their paper.

“As Swift approaches its 20th anniversary, it’s incredible to see all the new science it’s still helping the community accomplish,” said S. Bradley Cenko, Swift’s principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “There’s still so much it has left to teach us about our ever-changing cosmos.”

NASA’s missions are part of a growing, worldwide network watching for changes in the sky to solve mysteries of how the universe works.

Goddard manages the Swift mission in collaboration with Penn State, the Los Alamos National Laboratory in New Mexico, and Northrop Grumman Space Systems in Dulles, Virginia. Other partners include the University of Leicester and Mullard Space Science Laboratory in the United Kingdom, Brera Observatory in Italy, and the Italian Space Agency.

since I’ve been alive in San Diego, we always had yellow lights prevalent in parking lots and most areas

it was the rule street light, etc. had to be like yellow cast no white light

so nowadays I noticed that there is white light. the reason we didn’t have it for so long is because of the observatory on Palomar mountain the white light would hinder the vision of the telescopes big space eye. I reckon the new lights, LED or whatever they are don’t disturb the telescope.

469705 ǂKá̦gára

469705 ǂKá̦gára  (Put a Ring On It ~ 16 Feb 2023, Philip Sedgwick)

Evidently, the powers overseeing the celestial canopy took this message to heart. Rings are common around planetary objects. Saturn leads the pack as the ringed master in our solar system. Then there’s Jupiter, Uranus, Neptune all sporting rings and demolishing previous associations that rings around a planet - specifically Saturn - represent restrictions for those in the real world to overcome.

Jupiter and Uranus hopefully deposited that association about overly-maligned Saturn in the appropriate dumpster. After all, as if competing with the announcement of even more moons discovered around Jupiter, Saturn recently tantalized telescope cameras by sporting mysterious spokes fleeting across his rings. No doubt those rings consist of high-quality and cosmic clarity reflecting cosmic light for the wonder of all.

Did you know the centaurs Chiron and Chariklo (last call for the Twin Stars Relationship Report that features these two centaurs, e-mail for details) have rings. Did you know as well that the dwarf planet Haumea is confirmed to have rings? Now we find out that Quaoar, the first solar system object (and likely dwarf planet) named for indigenous peoples shows off a ring that currently drives astronomers to scratch their heads.

Quaoar possesses a satellite body (moon) close. This object is Weywot (Sky Father). However the position of Quaoar’s ring relative to it and its moon, doesn’t fall within previously demarcated demonstrated limits. As such, this ring defies previous theories for where ring material is likely to be located relative to the body it surrounds. By no means should a ring be kept in a box, or defined by pigeon hole, for that matter. Why is Quaoar so intriguing at present from an astrological point of view and what does this mean to those of us on Earth? Is it about being out of the box?

Discovered in June 2002 by the team of Mike Brown and Chad Trujillo at Palomar Observatory, the name Quaoar was chosen for the primary creation deity of the Tongva people residing near the observatory around what is now Los Angeles. As a creation god, Quaoar sang and danced other deities into existence and brought about life.

Currently, Quaoar in Capricorn squares Jupiter in Aries. Given perihelion in Pisces and node in Libra, Quaoar seeks to remind all of the importance of all relations and the complex weaving between all persons on the planet and their actions regardless of proximity. Equally important to highlight Jupiter’s influence, one must clarify that personal rituals and creative protocols are part of ones figurative song and dance to conjure positive results from life. As such since personal ceremonies must not be perceived as a dog and pony show, even if they appear out of the box. Simply, such actions seek to enliven the sincerest soul reach available at the time of creative conjuring.

Also in the category of objects that peal with a notable resonance is the naming of the Kuiper Belt Object 469705 (former provisional designation was 2005 EF298) as Ká̦gára. Actually this consists of a binary system between the namesake object and !Hãunu. Ká̦gára was discovered at Arizona’s Kitt Peak Observatory on 11 March 2005. The secondary body first appeared courtesy of the Hubble Space Telescope in 2009. Ká̦gára is estimated to be approximately 140 kilometers in diameter and the period of the binary pair runs 9.65 days. The overall orbital period stands at 292.45 years. This is the third named pair of Kuiper Belt Objects, the previous two pairs: Mors-Somnus and Sila-Nunam.

Today, the binary KBO retrogrades through 26 Virgo 38.

The source mythology originates with the ǀXam people of the Karoo region of southern Africa. According to lore, Ká̦gára, following a dispute with his brother-in-law, !Hãunu, sought to return his younger sister, the wife of !Hãunu, to their parents. !Hãunu raged after the siblings hurling lightning from mountainous clouds at them as they fled. One of the lighting bolts bounced back to strike !Hãunu. While Ká̦gára and his sister were unharmed, !Hãunu slowly died amidst the shaking of the thunder. There appears to be a similar tale in Australian Aboriginal mythology.

This successful tale of rescue and retrieval comes from a Kuiper Object with a north node of 28 Cancer 03 and perihelion (closest contact with the Sun) at 15 Libra 18 (NOTE: both coordinates are heliocentric). Whether the naming astronomer intended to do so or not, he nailed the tension often found between familial and interpersonal relationships as demonstrated by the nature of the signs of the orbital elements.

While becoming aware of this object only yesterday, beside the obvious intended resolution between relationship factions, interpretive concepts are still in the state of speculation. This comes to our attention on the heels of scores of thousands perishing in Syria and Turkey during the rumbling of a series of massive earthquakes. However, all elements of mountainous thunderstorms may be eligible to apply for consideration regarding shifting meteorological and climate considerations. Seeking the means to resolve personal, familial, tribal and cultural disputes gains importance, especially through the current position of this system in Virgo. Seek to overcome judgment, criticism and trolling while positively applying the trines to Pluto in Capricorn and Sedna in Taurus. Always seek to apply transformation magic to all real world circumstances, and so engage with the wisdom granted by diving deep into what fosters ones life and soul in grounded, practical realities.

Couple of loosely applied prescriptions for Ká̦gára, for sure. Leave lightning bolt hurling to those deity possessing a specific craft, skill and charge for such activity, and make no effort to steal anyone’s thunder.

More soon!

'First light': NASA receives laser beam message from 16 million kilometers away

Fernando Valduga By Fernando Valduga 11/27/2023 - 08:43 in Space, Technology

An innovative experiment flying aboard NASA's Psyche mission has just reached its first major milestone by successfully carrying out the most distant demonstration of laser communications.

The technological demonstration may one day help NASA's missions to investigate space more deeply and discover more discoveries about the origin of the universe.

Launched in mid-October, Psyche is currently on its way to humanity's first glimpse of a metallic asteroid between the orbits of Mars and Jupiter. The probe will spend the next six years traveling about 3.6 billion kilometers to reach its namesake, located on the outside of the main asteroid belt.

Along with the tour is the demonstration of Deep Space Optical Communications technology, or DSOC, which is carrying out its own mission during the first two years of the trip.

The technological demonstration was designed to be the most distant experiment of the U.S. space agency of high-bandwidth laser communications, testing the sending and receiving of data to and from Earth using a near-infrared invisible laser. The laser can send data from 10 to 100 times the speed of traditional radio wave systems that NASA uses in other missions. If it is totally successful in the coming years, this experience could be the future basis of the technology used to communicate with humans who explore Mars.

And the DSOC recently achieved what engineers called the "first light", the feat of successfully sending and receiving their first data.

The experiment sent for the first time a laser encoded with data from far beyond the Moon. The test data were sent from almost 16 million kilometers away and arrived at the Hale Telescope at the Palomar Observatory of the California Institute of Technology in Pasadena, California.

The distance between DSOC and Hale was about 40 times greater than the Moon is from Earth.

Psyche Probe.

“Achieveing the first light is one of the many critical milestones of the DSOC in the coming months, paving the way for communications with higher data rates, capable of sending scientific information, high-definition images and video streaming in support of humanity's next giant leap: sending human beings to Mars,” Trudy Kortes, director of technology demonstrations at NASA's Directorate of Space Technology Missions, said in a statement.

Sending lasers through space

The first light, which occurred on November 14, happened when the laser flight transceiver instrument in Psyche received a laser beacon sent from the Optical Communications Telescope Laboratory at the Table Mountain facility of NASA's Jet Propulsion Laboratory near Wrightwood, California.

The initial beacon received by Psyche's transceiver helped the instrument point its laser to send data back to the Hale Telescope, which is located about 160 kilometers south of Table Mountain.

“The test (of November 14) was the first to fully incorporate ground resources and the flight transceiver, requiring the DSOC and Psyche operations teams to work together,” Meera Srinivasan, DSOC operations leader at JPL, located in Pasadena, California, said in a statement. "It was a formidable challenge and we have much more work to do, but in a short time we were able to transmit, receive and decode some data."

This is not the first time that laser communications have been tested in space. The first bidirectional laser communication test took place in December 2021, when NASA's Laser Communications Relay Demonstration was launched and went into orbit about 22,000 miles (35,406 kilometers) from Earth.

Since then, experiments have sent optical communications from the Earth's low orbit to the Moon. And the Artemis II spacecraft will use laser communications to send high-definition videos of a manned trip around the Moon. But DSOC marks the first time that laser communications have been sent through deep space, which requires incredibly accurate aiming and pointing over millions of kilometers.

The initial test of the capabilities of the technical demonstration will allow the team to work on the refinement of the systems used in the laser pointing accuracy. As soon as the team ticks this box, the DSOC will be ready to send and receive data to the Hale Telescope as the spacecraft moves away from Earth.

Future challenges

Although the DSOC does not send scientific data collected by the Psyche spacecraft because it is an experiment, the laser will be used to send bits of test data encoded in the photons of the laser, or quantum light particles.

Detector matrices on Earth can capture the Psyche signal and extract the data from the photons. This type of optical communication can change the way NASA sends and receives data from its deep space missions.

“Optical communication is a blessing for scientists and researchers who always want more from their space missions and will allow human exploration of deep space,” Dr. Jason Mitchell, director of the Advanced Communications and Navigation Technologies Division of the Department of Communications and NASA's Space Navigation program said in a statement. "More data means more discoveries."

As Psyche continues his journey, more challenges await him.

The DSOC team will monitor how long it takes for laser messages to travel through space. During the first light, the laser took only 50 seconds to travel from Psyche to Earth. At the farthest distance between the spacecraft and the Earth, the laser is expected to take 20 minutes to travel one direction. And during that time, the spacecraft will continue to move and the Earth will rotate.

Meanwhile, the Psyche spacecraft continues to prepare for its main mission, connecting propulsion systems and testing the scientific instruments needed to study the asteroid when it arrives in July 2029. The mission will be able to determine whether the asteroid is the exposed nucleus of an ancient planetary building block since the beginning of the solar system.

NASA’s Laser Comms Demo Makes Deep Space Record, Completes First Phase

The Deep Space Optical Communications tech demo has completed several key milestones, culminating in sending a signal to Mars’ farthest distance from Earth.

NASA’s Deep Space Optical Communications technology demonstration broke yet another record for laser communications this summer by sending a laser signal from Earth to NASA’s Psyche spacecraft about 290 million miles (460 million kilometers) away. That’s the same distance between our planet and Mars when the two planets are farthest apart.

Soon after reaching that milestone on July 29, the technology demonstration concluded the first phase of its operations since launching aboard Psyche on Oct. 13, 2023.

“The milestone is significant. Laser communication requires a very high level of precision, and before we launched with Psyche, we didn’t know how much performance degradation we would see at our farthest distances,” said Meera Srinivasan, the project’s operations lead at NASA’s Jet Propulsion Laboratory in Southern California. “Now the techniques we use to track and point have been verified, confirming that optical communications can be a robust and transformative way to explore the solar system.”

Managed by JPL, the Deep Space Optical Communications experiment consists of a flight laser transceiver and two ground stations. Caltech’s historic 200-inch (5-meter) aperture Hale Telescope at Caltech’s Palomar Observatory in San Diego County, California, acts as the downlink station to which the laser transceiver sends its data from deep space. The Optical Communications Telescope Laboratory at JPL’s Table Mountain facility near Wrightwood, California, acts as the uplink station, capable of transmitting 7 kilowatts of laser power to send data to the transceiver.

By transporting data at rates up to 100 times higher than radio frequencies, lasers can enable the transmission of complex scientific information as well as high-definition imagery and video, which are needed to support humanity’s next giant leap when astronauts travel to Mars and beyond.

As for the spacecraft, Psyche remains healthy and stable, using ion propulsion to accelerate toward a metal-rich asteroid in the main asteroid belt between Mars and Jupiter.

Exceeding Goals

The technology demonstration’s data is sent to and from Psyche as bits encoded in near-infrared light, which has a higher frequency than radio waves. That higher frequency enables more data to be packed into a transmission, allowing far higher rates of data transfer.

Even when Psyche was about 33 million miles (53 million kilometers) away — comparable to Mars’ closest approach to Earth — the technology demonstration could transmit data at the system’s maximum rate of 267 megabits per second. That bit rate is similar to broadband internet download speeds. As the spacecraft travels farther away, the rate at which it can send and receive data is reduced, as expected.

On June 24, when Psyche was about 240 million miles (390 million kilometers) from Earth — more than 2½ times the distance between our planet and the Sun — the project achieved a sustained downlink data rate of 6.25 megabits per second, with a maximum rate of 8.3 megabits per second. While this rate is significantly lower than the experiment’s maximum, it is far higher than what a radio frequency communications system using comparable power can achieve over that distance.

This Is a Test

The goal of Deep Space Optical Communications is to demonstrate technology that can reliably transmit data at higher speeds than other space communication technologies like radio frequency systems. In seeking to achieve this goal, the project had an opportunity to test unique data sets like art and high-definition video along with engineering data from the Psyche spacecraft. For example, one downlink included digital versions of Arizona State University’s “Psyche Inspired” artwork, images of the team’s pets, and a 45-second ultra-high-definition video that spoofs television test patterns from the previous century and depicts scenes from Earth and space.

The technology demonstration beamed the first ultra-high-definition video from space, featuring a cat named Taters, from the Psyche spacecraft to Earth on Dec. 11, 2023, from 19 million miles away. (Artwork, images, and videos were uploaded to Psyche and stored in its memory before launch.)

“A key goal for the system was to prove that the data-rate reduction was proportional to the inverse square of distance,” said Abi Biswas, the technology demonstration’s project technologist at JPL. “We met that goal and transferred huge quantities of test data to and from the Psyche spacecraft via laser.” Almost 11 terabits of data have been downlinked during the first phase of the demo.

The flight transceiver is powered down and will be powered back up on Nov. 4. That activity will prove that the flight hardware can operate for at least a year.

“We’ll power on the flight laser transceiver and do a short checkout of its functionality,” said Ken Andrews, project flight operations lead at JPL. “Once that’s achieved, we can look forward to operating the transceiver at its full design capabilities during our post-conjunction phase that starts later in the year.”

More About Deep Space Optical Communications

This demonstration is the latest in a series of optical communication experiments funded by the Space Technology Mission Directorate’s Technology Demonstration Missions Program managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, and the agency’s SCaN (Space Communications and Navigation) program within the Space Operations Mission Directorate. Development of the flight laser transceiver is supported by MIT Lincoln Laboratory, L3 Harris, CACI, First Mode, and Controlled Dynamics Inc. Fibertek, Coherent, Caltech Optical Observatories, and Dotfast support the ground systems. Some of the technology was developed through NASA’s Small Business Innovation Research program.

Luego he seguido el entrenamiento [por cierto..al principio he cruzado el PARKING del parque JUAN CARLOS I junto a la vía del TREN donde hicieron el concierto con BAD RELIGION y UZZUHAIA= CD Destino PERDICION.. en 2007..y me ha puesto nervioso un tipo con un MERCEDES BLANCO clase A que no me adelantaba apesar de subir una dura CUESTA ..Parecia como si fuera el LIDER DEL PELOTON y luego veo al acabarla AXFISIADO por no entorpercer la cola que iba formando y parar ..que llevaba una L y debía de ser de Segunda mano cosa que recomiendo en cualquier cosa cuando uno empieza con algo como las MOTOS..pues eres propenso a las hostias..

..y acabe el entrenamiento fijándome apesar de que iba por sentido contrario rodando como a 35 KM/HR [pues con las ruedas lisas parece que tienes otra bici y más si le cambio la horquilla o suspensión por una mejor..por lo qud veo absurdo sobre todo en mountain bike llevar pedales con anclaje me parecen ademas mas inseguros]..con una pintada con AMOR LIBRE..además separadas las palabras y me di la vuelta hacer la foto.

Por cierto.. ese SUPERCOR de VALDEBEBAS [un barrio nuevo de lujo que tiene cero vida social..es decir..no ves a casi nadie por las calles] esta en la avenida FRAGA ministro de Turismo y comunicación de FRANCO cuando 2 aviones USA chocaron entre ellos cayendo Bombas Atómicas en PALOMARES [entre la playa nudista de VERA=CIERTO..y la de VILLA_RICOS=Festival DREAM_BEACH con acampada en PINAR en la playa de PALOMARES donde estuve en agosto 2015 lleno BORRACHOS, FUMATAS, DROGATAS, ATONTADOS por la MUSICA ELECTRONICA cerrando de 7 AM a 9 AM el millonario ARMIN VAN BUUREN al que vi la NOCHEVIEJA 2010 en MELBOURNE en su ESTADIO CONVERTIBLE "MARVEL" entonces ETIHAD donde semanas antes vi la gira 360 de U2 y CIRCLE de BON JOVI..por lo que tras acabar ARMIN me fui sin recoger la tienda de campaña que por cierto me ayudo a poner una chica con la que me folle una noche los 2 muy borrachos al volver del festival..y me fui directo en bus a la pensión LA PURISIMA de CARTAGENA donde VIRGINIA MAESTRO por entonces tocó en LA OTRA CASA posando con cartel de que EL SEXO ES LA DISTANCIA INEXISTENTE ENTRE 2 CUERPOS Y EL BUEN SEXO LA DISTANCIA INEXISTENTE ENTRE 2 MENTES..así como otro con ERES MI BRUJA PERO CUANDO QUIERES ME HACES VOLAR COMO SI TUVIERAS ALAS DE ANGEL ..y entre un tipo con JERSEY con HACER LO CORRECTO ES ABURRIDO en INGLES y otro con camiseta de asesinado LENNON con emblema de Peace]..y para demostrar que no había radiación se baño FRAGA con EMBAJADOR USA
