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
Myrtle Beach, South Carolina's police department is dealing with national scrutiny after police removed a man after he reportedly purchased a meal for homeless man inside of a McDonald's.The incident, which took place on Wednesday, was recorded on video, and has since gone viral, generating a national buzz. Nearly 40 million people have viewed the video in the 24 hours since it has been released. The incident happened after police were attempting to remove a man, who is reportedly homeless was eating a meal inside McDonald's. The man recording the incident claimed that he brought the man into the McDonald's and purchased him a meal."You guys suck... He didn't ask me for food, I saw him across the street and brought him over here for food," Yossi Gallo said. Gallo was then warned that he was being disorderly."I’m getting kicked out of here because I gave a homeless guy food,” Yossi Gallo said on the video he posted. Gallo and the homeless man were removed from the McDonald's by police. Police claim that the homeless man was asking people for money. A claim Gallo disputed. Myrtle Beach Police released a statement involving Wednesday's incident: Officers were dispatched to the location after receiving a call, from an employee of the business, that a male was in the parking lot asking people for money. Upon arriving at the restaurant, an employee approached the officer and indicated the male was inside the establishment. The employee requested the officer issue a trespassing warning and asked that the person leave the premises. The officer advised the male of the request made by the business and issued the warning. A bystander, who was videotaping the incident was also trespassed from the location, at the request of the manager, for what management deemed as disorderly behavior. 1858
MILWAUKEE, Wis. -- Joe Biden will not be traveling to Milwaukee to accept the Democratic presidential nomination, the Democratic National Convention Committee announced Wednesday.The DNCC said Biden would not be accepting the nomination at the Democratic National Convention, which is scheduled to begin on Aug. 17, citing coronavirus as the reason.Other speakers for the DNC will also no longer travel to Milwaukee. Biden will instead accept the nomination in Delaware.“From the very beginning of this pandemic, we put the health and safety of the American people first. We followed the science, listened to doctors and public health experts, and we continued making adjustments to our plans in order to protect lives. That’s the kind of steady and responsible leadership America deserves. And that’s the leadership Joe Biden will bring to the White House,” said DNC Chair Tom Perez in a press release.“2020 will always be remembered as a year of once-in-a-lifetime challenges and changes—but it will also be remembered as a time when Americans were their most compassionate and resilient selves. While we wish we could move forward with welcoming the world to beautiful Milwaukee in two weeks, we recognize protecting the health of our host community and everyone involved with this convention must be paramount,” said Joe Solmonese, CEO of the 2020 Democratic National Convention.The convention is scheduled to take place at the Wisconsin Center Aug. 17 through Aug. 20. 1481
NASHVILLE, Tenn. — AT&T said crews have made significant progress restoring service to the region on Sunday morning following an explosion on Friday morning outside an AT&T data center.The explosion impacted widespread service interruption reaching outside of just Middle Tennessee. On Sunday morning, the company said power has been restored to four floors of the building and more than 65% of mobile sites affected by the explosion have been restored. More than three feet of water was pumped out of the building's basement on Saturday, however, access to some of the lowers is still limited. AT&T said on Sunday crews will be adding additional cabling and more generators to provide more power into the building to help with restoration efforts."Teams are working to safely bring additional equipment online and reroute services through other facilities in the region. While mobility services have been restored in many areas, we still have more than 17 portable cell sites on the air to aid in communication, including for restoration teams and first responders," AT&T said in an update. "We are bringing in additional resources to support the recovery of wireline voice and data services and expect to have a fleet of 24 additional trailers of disaster recovery equipment on-site by the end of the day."The company did not provide an exact time when it expects service to fully be restored. Metro officials said there will be times customers will lose service as restoration efforts continue but officials are confident to be running at full capacity by the end of Sunday.Damage to the building is still being assessed.This story was first published by Caroline Sutton at WTVF in Nashville, Tennessee. 1730
Nearly a full year after the season started, the 2020-21 NHL season finally came to a close with the Tampa Bay Lightning winning its first Stanley Cup in 16 years by defeating the Dallas Stars on Monday. The Lightning won the best-of-seven series 4-2 after winning Monday’s Game 6 contest by a 2-0 ledger.The Lightning won the Stanley Cup despite not having the services of its top forward Steven Stamkos for most of the playoffs. Stamkos briefly played in Game 3 of the Stanley Cup Finals, and he even scored a goal in his short appearance.The NHL suspended its season on March 12 due to the coronavirus pandemic. After a nearly four-month hiatus, the NHL resumed action with a 24-team playoff held in two “hub” cities – Edmonton and Toronto.The entirety of the Stanley Cup Finals was played in Edmonton.Stepping up for the absent Stamkos, Nikita Kucherov and Brayden Point helped the Lightning to victory. Kucherov had a league-leading 32 points in the playoffs, followed by 31 points for Point.But it was defender Victor Hedman who won the the Conn Smythe Trophy for the playoff's most valuable player.The Lightning’s goalie, Andrei Vasilevskiy, also stepped up with an under 2 goals against average.The Lightning’s Stanley Cup victory avenged the ending to the Lightning’s 2019 season. After winning last year’s Presidents’ Trophy, the Lightning was swept by the Columbus Blue Jackets in the first round of the playoffs. Columbus was the last team from the Eastern Conference to make the playoffs last year. 1519
