NASA could make history on Tuesday as their spacecraft, OSIRIS-REx, will attempt to land on an ancient asteroid 200 million miles away from Earth.OSIRIS-REx launched in 2016. It arrived at the asteroid, named Bennu, in 2018 and it’s been mapping out the surface working to pick the best location to land ever since.The mission’s operations are headquartered at the University of Arizona.The mission will begin at 2:50 p.m. Arizona time on Tuesday. At 3:12 p.m., OSIRIS-REx will finally touch down on Bennu and collect a sample before heading back to Earth. Dr. Lori Glaze with NASA tells ABC15 the sample will allow researchers to study the ancient secrets of our solar system. She says Bennu also has a 1-in-2,700 chance of impacting Earth in about 150 years or so, so this mission can help researchers work to prevent that.“Helping us refine and reduce the uncertainties on Bennu’s orbit so we can better predict more precisely not only when it might intercept with Earth, but what the probability of that intersection is,” Dr. Glaze said. “So the mission's been critically important for refining Bennu’s orbit so we can help protect ourselves in the future.”Watch a live stream of the event in the player below. 1222

(KGTV) — A teenager is dead after police found him suffering from a gunshot wound in a South Bay alley early Friday.The 17-year-old male was found in the west alley of 1900 C Avenue with a gunshot wound just before 1:30 a.m., according to National City Police Department.Firefighters and first responders arrived at the scene to perform life-saving measures, but the teen died at the scene. His identity has not been released.Police did not release any further information on the case.National City Police ask anyone with information to call the department at 619-336-4460. 603

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

NAMPA, Idaho -- An Idaho woman decided to become a surrogate after giving birth to her son in 2018, because she wanted to give the gift of motherhood to someone else. After consulting with her husband, Emily Chrislip started the process in February 2019."We couldn't imagine what we would do without our own biological child, so we started looking into surrogacy and applied to some California agencies," Chrislip said.By September of that year, Emily was chosen as a surrogate for a couple in China. The process went as expected, up until two months before giving birth, when COVID-19 was declared a pandemic and travel restrictions were put in place."So, the plan was to get here before the due date, and we were going to let them be in the delivery room. They were going to be a part of it, see her be born. So when she was born, they were supposed to get their own room at the hospital with the baby, and my husband and I would've had our own room, and my job was done at that point," Chrislip said.But things didn't go as planned. More than four months later, Emily is still caring for the baby even though the original plan was to hand the baby off as soon as she gave birth."I actually had some people I work with ask what about the baby's parents, and I was like, 'Oh shoot I don't know what's going to happen,' and so that's what started bringing up conversations like, 'OK, what's going to happen if they can't get here?,'" Chrislip said.The biological parents had the option of having a nanny agency care for the baby until they could travel to the U.S. to pick the baby up, but instead asked Emily and her husband if they would step in and care for her.Emily says she put herself in the parent's shoes and knew she had to care for the baby."So we were like, 'well alright, we'll take care of her,' it will be a max four weeks, we can do that, and now here we are and still don't know when they'll be here," Chrislip said.The first obstacle the biological parents faced with getting to the U.S. was the travel restrictions, but now getting a flight is nearly impossible since flights from China to the U.S. have decreased to one per week.Although the future looks uncertain, Emily says she doesn't mind caring for the baby in the meantime."So, we'll keep taking care of her, keep doing what we're doing and just kind of take it a week at a time until there's something more set in stone on when they're going to be here," Chrislip said.This story was originally published by Stephanie Garibay at KIVI. 2520

NASHVILLE, Tenn. – The NFL has postponed Sunday’s game between the Tennessee Titans and Pittsburgh Steelers to allow for additional time for COVID-19 testing.In a statement released Wednesday, the league said it wants to ensure the health and safety of players, coaches and game day personnel.The NFL said the game will be played on either Monday or Tuesday. The date and time will be announced “as soon as possible.”New from the league pic.twitter.com/RnLcZ9mSPj— Brian McCarthy (@NFLprguy) September 30, 2020 The postponement comes after at least three Titans players and five employees for the team tested positive for the novel coronavirus. Coach Mike Vrabel said some of those who tested positive are experiencing flu-like symptoms, but nothing out of the ordinary.Following the positive tests, the NFL said the Titans would suspend in-person club activities, as would the Minnesota Vikings, who played the Titans on Sunday.The Vikings said in a statement Tuesday that none of their players or personnel members have tested positive for the virus since their game.“Both clubs are working closely with the NFL and NFLPA, including our infectious disease experts, to evaluate close contacts, perform additional testing and monitor developments,” the NFL said.The Titans' outbreak marks the biggest COVID-19 scare the league has experienced to date. Between Aug. 21 and Sept. 19, the league conducted 180,274 COVID-19 tests among players and team personnel. Just 30 of those tests have come back positive.This weekend's game was supposed to be the first of the season that Tennessee fans would be allowed inside Nissan Stadium, WTVF reports. 1651
