NASA Achieves Impressive Bandwidth with its New Laser Communications System

Ships passing in the night used Morse code sent with lanterns and shutters to communicate. That same basic principle has allowed NASA to communicate with Psyche, its mission to a metal-rich asteroid in the main belt. However, the “light” was a version of heat, and instead of being able to see each other, Psyche is 240 million miles away from Earth. Oh, and the upload rate of the data it sent is still better than old dial-up internet connections that were prevalent not so long ago. This feat was part of the culmination of the first Phase of NASA’s Deep Space Optical Communications experiment. Psyche is carrying a laser transceiver tuned to a specific frequency of infrared light, which can also be transmitted and received by two ground stations based in California. The infrared frequency the mission planner at NASA’s Jet Propulsion Laboratory selected is much higher than the typical radio frequency communications used for deep space missions. In this case, higher frequency also means higher data rate. As part of its Phase I operations, the experiment transmitted data to and from Psyche at an astonishing 267 megabits per second when the spacecraft was as far away as Mars when the Red Planet is closest to us. That is equivalent to a typical wired broadband connection back here on Earth. But it was made in space – with lasers. Video that Psyche sent back to Earth.Credit – JPLraw YouTube Channel In June, Psyche reached a new milestone for distance from Earth – 390 million km. That is equivalent to Earth and Mars’ farthest distance from each other. During this window, operators managed to maintain a 6.25 megabits per second download link. While that’s a few orders of magnitude slower than the maximum data rate it reached the closer distance, it is still orders of magnitude above the same data rate of a radio frequency connection with the same power output. As part of this Phase I test, what else would NASA send from its spacecraft but a cat video—in this case, an ultra-high-definition video of a cat named Taters chasing a red laser pointer for 15 seconds straight. As a proof of concept for a high-speed communication line, most of the internet would agree that this is a good use of bandwidth.  Ultimately, the latest successful connection in June was the end of the first Phase of testing for the system. The project team unequivocally proved that, as expected, communication data-rate reduction was proportional to the inverse square of the distance between Earth and Psyche. In other words, the data rate decreases even faster as the distance increases between the spacecraft and the base station.  Taters probably didn’t understand how important it was that he catch the laser – but he was trying his best anyway.Credit – NASA / Associated Press YouTube Channel A second phase of the experiment will pick up in November when the laser transceiver is turned back on again. At that point, it will prove the system can operate for more than a year, and eventually, the system will be brought up into full operational mode later in 2024. Psyche is scheduled to arrive at its target asteroid in 2029, so the team will have plenty of time to prep their system for operation before that time. There is also a backup radio frequency communication system on Psyche in case the laser system fails – and even that is still faster than lanterns and shutters.

Neil Oliver Interviews Dr Clare Craig - Under attack!!!

…a runaway train with no brakes… UTL COMMENT:- Appreciate this upfront, thoughtful, and honest dialogue. Dr. Clare hits the mark addressing how we have to be braver about looking at evil, rather than simply brushing things aside that we don’t want to think or talk about (e.g. the covid massive human 'experimental' (THEY WEREN'T) injections debacle). Hard to brush aside unprecedented numbers of “died suddenly”, heart attacks in kids, un-treatable cancers. So when WILL the Corporate NWO controlled 'Govts'/media and others start to face reality instead of continuing to sweep all of this evil fallout under the rug of “trust the science”? Ummmm maybe that's why they don't because they're all owned and controlled by the NWO? Hmmmm...

??? Lidia Thorpe interrupts 'King Charles Welcome Ceremony' at Parliament House in Canberra.

Kinda looks a bit staged perhaps? Totally dislike NWO fool King Charles however she should still be burned at the stake for that!! Or hung, drawn and quartered? That's what Kings used to do for such insolence, no? That embarrassingly useless POS Thorpe must also remember that she is barely even 'Aboriginal' she is majority WHITE!!

81-year-old woman votes for the first time after years of being told her vote didn't matter

On the eve of her 82nd birthday, Georgia woman Betty Cartledge did something she had never done before—she voted. On Wednesday, Oct. 16, one day after early voting began in Georgia, local television station Channel 2 Action News spotted Cartledge on her way into a Newton County polling location in Atlanta.That’s when she shared with the outlet, "I’m going to vote for the first time in my life.”Why hadn’t this woman ever been to the ballot box? Because her longtime husband, who had also never voted before, discouraged the idea. “I was so young and everything when we got married, I never really thought about it,” she said. “And then I got old and I thought that it wouldn’t count to vote.”But after her husband died in April of 2023, and after (according to Good Morning America) seeing ever rising costs of living, Cartledge decided that this year, she’d do things differently. However, there was still the challenge of not being able to read or write. For that, Cartledge relied on her niece Wanda Moore, who helped her register and accompanied her to the ballot box. @theskimm Say it with us: Good for her. #voting #voter #georgia #georgiavoters #election #2024elections #presidentialelection ♬ original sound - theSkimm And when they arrived at the polling station, things went smoothly. "We went in and she told the lady I couldn't read and write, and she told her what to do," Cartledge recalled. "And I went over there, and I done it on my own. I done my own voting. I had nobody tell me who to vote for or what. She just showed me, read everything to me, and then I voted."All in all, Cartledge dubbed it a “neat” experience, saying "If I'm here, I'll be back again."She also shared with the Washington Post how it instilled a sense of patriotic pride, saying “It made me feel like I was American, and I was standing up for my rights.”Moore has been equally thrilled with her aunt’s voting experience, and thinks it could inspire other older Americans that their voice counts. “They are people too, and they matter,” she said.It wasn’t long before Cartledge's big day began making the rounds on social media, where viewers both celebrated and mourned the occasion.Y'all need to listen to this incredible story about an 81-year-old women in Newton County, Georgia casting her vote for the first time. How many women in America are there who are repressed by controlling husbands? Unfortunately, I have a feeling there are quite a few. ?? pic.twitter.com/fwlT8KybhZ— Bill Madden (@maddenifico) October 17, 2024 This makes me think of my mother's mother, who explained away her non-participation by saying what difference does my one vote make. She was saintly in her personal life; she had to be to contend with my grandfather's stern authoritarianism.— denny burt (@dennyburt8) October 18, 2024 Inspiring to see Betty finally exercise her right to vote after all these years. Stories like this show the strength of individuals in shaping our democracy.— Marco V. Posas (@marco_v_posas) October 17, 2024 I don’t care who she voted for. I am just glad she was finally able to do it.— Quinn ?? ? (@QuinnBarsh) October 17, 2024 “Wow, so glad she was able to vote at least once,” one person wrote on X. “Amazing that men thought this way about our right to vote.”Still another noted, “This is wonderful. This election means so much, and it’s way bigger than what we ever thought.”All in all, Cartledge also hopes her story instills a bit of confidence in others from similar walks of life. In her interview with Good Morning America, Cartledge stressed the importance of people who don't have the ability to read or write to not get discouraged, because “it's not an impossible thing," when you ask for help. "Talk to [friends and family] and see if they'll help you out and go out there and do it. Do it for America. Do it for your country," Cartledge urged, adding that it's "never, ever" too late to vote.
