- The Hubble Space Telescope’s successor is wonderfully capable of seeing back to the beginning of time within a hair’s breadth. And now it’s on the verge of taking flight. It will be the largest and most potent astronomical observatory ever to leave the planet, with a complex architecture and a large mission. It is the most expensive and, by far, the most difficult to carry off, costing a whopping $10 billion.
After a long delay, the James Webb Space Telescope, which will launch on Friday, will look for the weak, glittering light from the first stars and galaxies, affording a view into cosmic genesis. Its infrared eyes will also search for alien worlds and black holes, examining planet atmospheres for water and other possible signs of life.
“That is why it is worthwhile to take chances.” In an interview with The Associated Press, NASA’s scientific mission leader Thomas Zurbuchen said, “It’s worth the anguish and the sleepless nights.” NASA Administrator Bill Nelson admitted that he is more concerned today than when the space shuttle Columbia first launched in 1986.
“There are over 300 things, and if even one of them goes wrong, it’s not going to be a pleasant day,” Nelson told the Associated Press. “As a result, everything has to operate flawlessly.” Because the Webb telescope is so large, it had to be folded in style to fit into the nose of the European Ariane rocket for launch from the French Guiana coast in South America. The sunshade is the size of a tennis court, and the light-collecting mirror is the size of many parking places. Once the spaceship is hurtling toward its perch 1 million miles away, it must reveal everything.
Sara Seager, a planet seeker at the Massachusetts Institute of Technology, stated, “We’ve been waiting a long time for this.” “Webb will help us go forward in our quest for life, but we’ll have to be extremely lucky to uncover any evidence of life.”
The 7-ton James Webb Space Telescope, named for the man who directed NASA during the 1960s space race, is 100 times more powerful than Hubble. Hubble, now 31 years old and still cranking out heavenly glamour photos, concentrates on visible and ultraviolet light, with a scattering of infrared light thrown in for good measure.
Webb will see things Hubble can’t since it’s an infrared or heat-sensing telescope, giving it “an altogether new viewpoint on the cosmos that will be just as awe-inspiring.
Webb will aim to go back in time 13.7 billion years, only 100 million years after the Big Bang when it formed the universe’s first stars. Scientists are curious to examine how closely these early galaxies resemble the Milky Way, if at all.
To beat Hubble, Webb will need a far more giant mirror, spanning 21 feet. It also requires a big canopy to shield the mirror and science instruments from the light and reflections from the Earth and moon. The gleaming, five-layered thin cover extends 70 feet by 46 feet and is necessary for maintaining a consistent subzero temperature of roughly minus 400 degrees Fahrenheit for all four sensors.
The most challenging component of the mission was unfolding and locking Webb’s mirror and sun-shield into proper position after launch. Each of the 18 motor-driven segments of the gold-plated mirror must be painstakingly positioned so that they can concentrate as one.
A company has developed a microchip implant that stores the status of your Covid vaccines beneath your skin:
A Swedish business has developed a microchip implant that can be put beneath the skin and retain information on a person’s vaccination status. Epicenter, a Stockholm-based firm, made news earlier this year when more than 100 workers implanted workplace access permits into their arms. It has now presented a device that consists of an NFC (Near Field Communications) implant that stores data that can be accessed using a reader device such as a smartphone that supports NFC.
“Implants are adaptable technology that it can utilize for many various purposes,” said Epicenter’s Chief Disruption Officer Hannes Sjöblad. “Right now, it is elementary to have Covid passport constantly accessible on your implant.”
“In case your phone runs out of battery, it’s always accessible to you,” Sjöblad noted. So, that’s how we utilize this technology today; next year, we’ll use it for something different.” Waving a smartphone over his arm, Sjöblad illustrated how the chip, which is the size of a grain of rice, works in a video. The phone’s screen then displays a paper showing his vaccination status.
The method, according to Sjöblad, is ‘reversible’ and does not involve the use of a specific phone app. “Any smartphone with NFC capability can read the implant,” he stated. If you go to a restaurant or a movie theatre, all you have to do is show your arm and swipe phone, and the Covid passport that you have on your chip shows up.”
To assist limit the spread of Covid-19, several venues in Sweden require confirmation of vaccination before allowing guests inside the premises. “It’s kind of like a QR code,” Sjöblad explained. “The only difference is that I don’t want a QR code on my skin.”
Although the implants are not yet for sale, Epicenter regularly offers ‘implant events’ for anyone interested in the notion. Patrick Mesterton, co-founder and CEO of Epicenter, said in a 2017 statement regarding the technology before it was utilized as a way of recording vaccination status: “The major benefit I think is ease.” “It effectively replaces a lot of items you have, such as credit cards or keys,” says the inventor.
Scientists at the Pentagon in the United States have created a high-tech implant that can detect Covid-19 under the skin. The Pentagon’s Defense Advanced Research Projects Agency has developed a sensor that can be implanted into a person’s body to identify the deadly virus, as well as a ground-breaking ‘filter’ to remove Covid from the bloodstream.
In an interview with CBS’ 60 Seconds, retired army infectious disease physician Colonel Matt Hepburn described how it all works. He was advised to ‘take pandemics off the table’ when DARPA hired him eight years ago.
According to Audrey Hepburn, “That was the DARPA model’s attractiveness. We challenge the scientific community to provide answers that may appear science fiction. We’re also ready to take a chance on high-risk ventures that may or may not pan out. However, if they do, we will be able to change the landscape radically.”
