NASA's OSIRIS-REx mission and the asteroid Bennu have had a date planned for two years, and just after noon ET today, they finally got to meet face to face. OSIRIS-REx fired its thrusters for a small burn, putting it about 4.3 miles from Bennu, marking the end of its journey to the asteroid.The mission -- which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer -- is NASA's first asteroid sample return mission. It launched in September 2016 and will spend two years up close and personal with Bennu. First images of the asteroid from the spacecraft's perspective have appeared as it got closer and closer.On Tuesday, the spacecraft will fly within 5 miles of Bennu, which will help design future orbits and map the surface.Over the next year, OSIRIS-REx will survey the asteroid using five scientific instruments on board the spacecraft. These instruments will help it determine a safe location from which to collect a small sample from Bennu's surface that will be returned to Earth in September 2023."Bennu's low gravity provides a unique challenge for the mission," said Rich Burns, OSIRIS-REx project manager at NASA's Goddard Space Flight Center. "At roughly 0.3 mile in diameter, Bennu will be the smallest object that any spacecraft has ever orbited."The sample from Bennu, a near-Earth asteroid, could help scientists understand not only more about asteroids that could impact Earth but about how planets formed and life began.OSIRIS-REx has a camera suite, a laser altimeter for 3D mapping, a thermal emission spectrometer to take temperature and mineral content and spectrometers to measure X-rays, nearly infrared and visible light.An arm mechanism called TAGSAM will reach out to collect the sample from Bennu's surface, making contact with the asteroid for five seconds in July 2020. During this contact, the arm will use a nitrogen gas burst to stir up rock and other materials on the surface so it can capture them. There is enough nitrogen for three attempts if the first is unsuccessful.NASA said the estimated 2.1-ounce sample size equates to about 30 sugar packets worth of dirt and rocks.The arm has a full range of motion, with joints capable of movement comparable to shoulder, elbow and wrist joints. It was "flexed" in space for the first time on November 14."The TAGSAM exercise is an important milestone, as the prime objective of the OSIRIS-REx mission is to return a sample of Bennu to Earth," said Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, Tucson. "This successful test shows that, when the time comes, TAGSAM is ready to reach out and tag the asteroid."In 2021, it will be time for the spacecraft to essentially turn around and begin its two-year journey home. The sample will be packed into a capsule that will drop in the Utah desert in 2023.For two years after the return, the sample will be cataloged and analyzed. Afterward, 75% of the returned sample will remain at NASA's Johnson Space Flight Center so it can be used for more research by scientists from around the world.Why did NASA select Bennu out of the 780,000 known asteroids in our solar system?It was discovered in 1999, and scientists have been studying it ever since. The asteroid fits a number of criteria that make it intriguing and convenient.Bennu is relatively close to Earth, and its orbit even crosses that of our planet, making a close approach every six years. Though small asteroids can rotate very quickly, Bennu has a diameter just a bit bigger than the height of the Empire State Building and rotates relatively slowly, each 4.3 hours. This means OSIRIS-REx can match its velocity and touch down briefly.The asteroid could pass close to Earth, closer than the moon, in 2135, with even closer approaches possible in 2175 and 2195. A direct hit is unlikely, but the data gathered during this mission can help determine the best ways to deflect near-Earth asteroids.The asteroid is also old and well-preserved, full of valuable materials that may even contain clues about how life began. Bennu is essentially a leftover from the formation of our solar system billions of years ago, although some of the minerals inside it could be even older.This carbon-rich asteroid could be full of organic molecules, metals, platinum and even water -- the essential ingredients for life. It's because of objects like Bennu that these resources were delivered to Earth during its formation.Asteroids could even serve as fuel stations for robotic and human missions if we can unlock the hydrogen and oxygen inside them, NASA said.Bennu probably broke off of a larger asteroid in the asteroid belt between Mars and Jupiter a couple billion years ago. This knocked it through space until an orbit close to Earth locked it in place. And Bennu is believed to be a grouping of rocks held together by gravity rather than a single object.But its orbit drifts 0.18 miles each year toward the sun, and OSIRIS-REx will enable researchers to understand why and to predict Bennu's movements. This could also explain how it ended up as a near-Earth asteroid."The story of this asteroid is the story of the solar system," said Bashar Rizk, instrument scientist for OSIRIS-REx. "When we understand Bennu, we will understand something fundamental about our solar system."The-CNN-Wire 5356

Mysterious packages are popping up on Medicare recipients’ doorsteps and the Federal Trade Commission said it’s part of a rising scam."That’s a back brace,” Anna Miller, a 94-year-old Medicare recipient said as she rifled through a package delivered to her home.Inside the box was a back brace, shoulder brace, and a couple of other pieces of medical equipment, the items came bundled together in a box addressed to Miller."They must have thought I was in bad shape to send me both of them in one box,” Miller joked.She said she never ordered any kind of medical device."I thought it was terrible because I figured it was false,” Miller said.As it turns out, her Medicare account got charged for the back and shoulder brace. It’s a scam the FTC said is on the rise targeting Medicare dollars and personal information.Miller reached out to Medicare to see what was going on. "They just said they'd look into it and they questioned me,” she said.Medicare followed up, sending a letter confirming an investigation into the matter. Meanwhile, the FTC is warning Medicare recipients to be aware.If someone calls and says they're with Medicare and offers you a “free” or “low cost” brace, hang up right away.Medicare will never call you with such an offer. Never give your Medicare or other personal information over the phone to anyone.If you do need a brace or medical equipment, talk to your doctor. Sellers on the phone don’t know what you need.Lastly, don't accept medical equipment you get in the mail unless you or your doctor ordered it. You don't have to pay for things you didn't order.2 Works for You Problem Solvers reached out to the company listed on the box sent to Miller, but have not heard back.If you are the victim of suspected Medicare fraud, CLICK HERE to report it to Medicare or the FTC immediatelyThis story was first reported by Cori Duke at KJRH in Tulsa, Oklahoma. 1894

Music can move the soul.Learning to carry a tune or play a chord can be a much-needed break from reality“Certainly, it helps people to heal in more than one way,” said Ty Hughes, music director at School of Rock Denver. He’s been teaching students online since the pandemic hit.“A lot of people are inspired to teach themselves a new skill or rather to work on a new skill, and take up a lot of the time they’re finding they have on their hands during these troubled times here,” he said.Recently, Hughes’ student base has grown from children to an older audience.“I’ve had at least about 75% more adults show up on my schedule these days,” he said.People like health care worker Janae Martinez, who started playing her guitar again while staying safe a home“It was very therapeutic for me in general,” she said of playing music. “So, I knew that I needed it again during the pandemic.”The mother of two says practicing playing helps her focus on things other than the virus.“It heals. It quiets my mind,” Martinez said. “It eases my soul if you will.”With more adults taking music lessons and picking up other hobbies during the pandemic, mental health experts say these activities can help the mind and body.“The feeling that I think some people had at the beginning of the pandemic is like, ‘everything is going to hell. How can I make the best of this,’” said Sean Ransom, Ph.D., clinical director at the Cognitive Behavioral Therapy Center of New Orleans.He says if things someone enjoys are taken away, like many were during the COVID-19 crisis, it helps to find something else that brings meaning into their life.“Hobbies have their own benefit that bring us a sense of accomplishment,” Ransom said. “They bring us a sense of growth.”While an online experience might not be enough for some people who prefer more social interaction, there’s still benefits from this type of training.“It’s been an adjustment but that’s what music has always been about is adapting to the times,” Hughes saidHe added that it’s never too late to learn something new.”Music is the healing answer,” Hughes said. ”Music is the magic. That’s what we’re going to keep going at.” 2169
