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

Minneapolis Mayor Jacob Frey requested the help of Minnesota's National Guard Wednesday after false rumors of an officer-involved shooting in the city prompted rioting and looting.On Wednesday evening, Frey imposed a city-wide curfew from 10 p.m. to 6 a.m. and asked for members of the National Guard in help patrolling his city's streets. Minnesota Gov. Tim Waltz declared a state of emergency and activated 150 State Patrol troopers, according to the Star-Tribune.The chain of events that led to looting and rioting began when police spotted a homicide suspect near Nicollet Mall. As police closed in on the suspect, he pulled out a gun and shot himself.The man who died has not yet been identified.The Minneapolis Police released surveillance video from the incident within 90 minutes of the shooting. Video does not show officers firing weapons but shows them appearing on the scene seconds after the self-inflicted gunshot wound.However, the incident sparked rumors online that officers had shot and killed the man. Hours later, a group of protesters gathered at Nicollet Mall to call for justice.Though some in the crowd attempted to inform the others that police were not involved in the shooting, the protests nonetheless devolved into looting. A Nordstrom Rack and a Target in the area were among the stores hit."This is a tragic incident for all involved," said Frey. "What the city needs now is healing, not more property destruction."Minneapolis saw several nights of violent protests in late May and early June, following the death of George Floyd at the hands of the city's police officers. Wednesday's incident also came as the nation grapples with the police shooting of Jacob Blake in Kenosha, Wisconsin. 1729

Moderna says that it will file for Emergency Use Authorization for its COVID-19 vaccine candidate after a primary efficacy analysis showed it to be 94% effective in preventing the virus.In a press release on Monday, Moderna said that a primary efficacy study of its vaccine candidate showed it to be 94% effective in preventing COVID-19 infection and that no participants who received the vaccine developed a severe case of the virus.According to Moderna's press release, of the 30,000 participants who took part in a Phase 3 trial, 196 have since contracted the virus. Of those participants, only 11 had received the vaccine — the other 185 had received a placebo. Only 30 people who took part in the trial have developed a severe case of the virus, all of whom received a placebo shot.The findings are consistent with efficacy figures released by Moderna just weeks ago. Moderna is the second U.S. company to seek Emergency Use Authorization for a COVID-19 vaccine. Pfizer submitted its application earlier this month.Like Pfizer's vaccine, the Moderna vaccine requires two shots that need to be taken 28 days apart. It also needs to be stored at ultra-cold temperatures before injection.Health experts say it is encouraging that there are multiple COVID-19 vaccine candidates that are nearing authorization, as the public will be less reliant on one vaccine in the unlikely event of safety issues.Experts like Dr. Anthony Fauci have said that there is a chance that some Americans in high-risk populations could begin receiving the vaccine in the coming weeks. However, COVID-19 vaccines won't be available for widespread use until the spring.Moderna's vaccine was funded in part by country singer Dolly Parton, who donated million to COVID-19 research at Vanderbilt University earlier this year. 1810

NATIONAL CITY, Calif. (KGTV) -- A family in National City says Immigration and Customs Enforcement (ICE) violated their rights during an arrest on Tuesday morning.  Brianna Alonso says her husband was heading to work when he saw ICE agents and ran back into his house. A spokesperson for ICE tells 10News 31-year-old Alberto Alonso-Hernandez is wanted for illegally re-entering the country 16 times since 2013 and for a domestic violence conviction in 2014.His wife disputes ICE's numbers. She says her husband was deported twice before Tuesday's arrest. She's upset because she says ICE agents never showed them a warrant before entering. Brianna says the agents gave her the warrant after her husband was in custody. However, according to a criminal attorney, ICE was just doing their job. Exercising the "no-knock" rule, where the officers do not have to show the warrant if they have probable cause that the suspect will get away or destroy possible evidence. ICE sent us the following statements regarding Tuesday's arrest:  1082

Millions of small businesses that received Paycheck Protection Program loans have been waiting for answers on how and when their loans would be forgiven. Now, the Small Business Administration has announced a plan that would forgive almost 70% of all the loans it gave out.“The new guidance that has come out from treasury department and the SBA aim to ease the process for applying for forgiveness of loans under ,000,” said Molly Day with the National Small Business Association.The new guidance forgives PPP loans that were ,000 or less, but also comes with a new rule. The rule allows businesses with no employees or businesses where the owner is the only employee, can now have most or all of their loan forgiven.Initially, most of the forgivable portion of a PPP loan was that which was used toward paying employees. The new rule also relaxes the scrutiny requirements on lenders to review documentation from small businesses proving how the money was spent.“A lot of small businesses don’t have employees, or they have one employee and that is themselves, adjusting that really makes it a lot more workable for the sole proprietors that are small businesses [and] are doing great work and deserve some assistance as well,” said Day.The forgiveness process laid out by the Small Business Administration does not have the usual red tape that comes with most government forgiveness processes. Business owners who received loans of ,000 or less have to fill out a one-page document, just released by the SBA, and have their lender process it.“I do think making the forgiveness process easier and more streamlined could help many small businesses,” added Day.With the loan debt hanging over their heads, many small businesses have been reluctant to take on additional debt or put more of their saving into their businesses. Relieving them of the loan burden could now allow them to do so and may result in saving some businesses that were on the brink.However, the SBA points out there’s no guarantee and is still pushing for continued support from Congress in the next stimulus bill. In addition, it is pushing for the SBA to extend the new guidance to loan 0,000 or less. 2195
