MIRAMAR, Calif. (KGTV) — Marine Corps Air Station Miramar held an annual mass casualty drill Tuesday ahead of this year's Miramar Air Show.The scenario, centered around an F-35 crashing off the end of the runway into the crowd, included about 20 people playing the part of the injured, complete with fake blood and shrapnel wounds."Getting everybody together is very crucial because one fire department, or one hospital, or one ambulance company cannot handle a large scale incident with a lot of patients," MCAS Miramar Fire Captain Paul Jacobs said.WHAT TO KNOW: MCAS Miramar Air Show 2019The importance is paramount as accidents have happened in the past. In October of 2004, a stunt pilot completed a loop too low and crashed into the flight line, wrecking the plane and ultimately killing the pilot.The base is also set to receive several F-35 aircraft this January.The annual drill helps the base, military personnel, firefighters and local ambulance companies work together and see if there are any weak points. Coordinating resources and communication are two key factors in the drill.The drill also highlights the air show's theme, "Salute to First Responders," as it illustrates how crucial personnel are when disaster strikes.The Miramar Air Show returns Sept. 27 - 29 and is free to the public. 1314

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

More than 40 percent of nonsmokers feel they should get 3-5 extra vacation days, according to a survey.E-cigarette maker Halo surveyed over 1,000 employed Americans about how fair they feel smoke breaks really are.Twenty-eight percent of smokers also felt that nonsmokers should be given three to five extra vacation days. However, the majority of smokers, 38 percent, didn't think nonsmokers should be given extra vacation days at all.The survey found that the average smoker spends roughly six days each year on smoke breaks at work. On average, Americans would give up smoking for 11 extra vacation days each year. Americans also believed companies should offer incentives for employees to quit smoking.The survey comes after nonsmoking employees at a Japanese agency received an additional six days of paid vacation time.  844

More people are experiencing hair loss related to the pandemic.A dermatologist tells us that before the coronavirus crisis, she was seeing one or two patients per day for shedding. Now, they account for about 10 patients a day, which is half her daily caseload.The patients can be broken into three categories. Some people are seeing a sudden onset of hair loss. Others have a known disease, like psoriasis or alopecia, and are now seeing flare ups. Both of those are attributed to added stress.Then, there's the patients who have had COVID-19 and are seeing shedding afterwards. That's not necessarily a direct result of the virus. It could be from the toll on the body.Patients who have recovered from other viral diseases have also experienced hair loss afterwards.“So, just the process of being sick, having a high fever, not eating well, those can be a shock to your system that can trigger hair shedding,” said Dr. Melissa Piliang, a dermatologist at the Cleveland Clinic.Hair loss patients who have had COVID-19 will have to work through their own recovery process. For those related to stress, you can try to manage it with things like exercise or meditation.“One sign of stress is hair loss, but there's probably other internal signs that you may not even realize that you're experiencing and things you're putting your body through so, recognizing the stress and doing things to mitigate that is a very important thing to do at this time," said Piliang.The American Academy of Dermatology Association says when hair loss is caused by fever or stress, it tends to return to normal on its own in less than a year.If you think your hair loss might be caused by something else, talk to an expert. 1710
