Most parents want to start saving for college while their child is young, but a new study by the Center for Michigan found that might be difficult.In Massachusetts, families with two children are paying, on average, more than ,000 for child care in a year. State tuition for colleges average around that same price."Reality hits when you become a parent,” says mom Yvette Schilling. “And you are working extra hard and working full time and so is your husband."  Schilling says when it comes to child care, the family has to be really mindful of the cost and budget accordingly.On average, parents pay nearly 0 a week for two children in child care. Care.com estimates it at more than ,000 a year.Figuring out how to pay for day care has been a struggle for many mothers."We don't have any family around, so that becomes a little bit of a challenge," Shilling says.  She says hiring a nanny would have cost her almost triple what she's paying for daycare.  "Is it worth it for me to work full time, so we can pay ,000, or should I just stay home and watch my kids myself?” Schilling asks.   So, how can parents save money for child care?According to the Care website, one option is to sign up for a dependent care account through your employer. You can set aside up to ,000 tax-free pay for child care.  If your employer doesn't offer a flexible spending account, take advantage of the child care tax credit. Each family can itemize child care expenses up to ,000 a year and apply a tax credit to it.  To off-set some costs, nanny sharing is becoming a popular trend, allowing two families to share a nanny and split the cost. 1685

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

MILWAUKEE — Christopher R. Ward has been charged with second-degree reckless homicide in the death of 14-year-old Jada Wright. Police responded to the scene late last Wednesday night at their home on the city's northwest side. According to police, Jada has cerebral palsy, and Ward was her personal care worker. Initially, the 18-year-old defendant reported to police that Jada had complications with her feeding earlier that night. He said was not involved in her death, and claimed she had a history of injuring herself.Jada's school physical therapist said she never saw Jada injure herself. She also said Jada was missing from school for a month.Ward was taken into custody after an autopsy revealed blunt force trauma to her abdomen.After further questioning, Ward admitted he had become frustrated with the girl while trying to feed her through her feeding tube. She had maneuvered her tube out of her stomach, frustrating him further. In response, he punched her in the stomach. Ward reconnected her tube and left the room. Upon returning, he saw she had vomited on herself, and did not seek additional care for her or tell first responders about his actions.    1207

  

NBA commissioner Adam Silver said Tuesday that he believes that the league's next season won't begin until 2021."We said a week ago or so that the earliest we would start is Christmas of this year," Silver told sportscaster Bob Costas during an appearance on CNN Tuesday. "But the more I'm learning and listening to Dr. Fauci this morning, I continue to believe that we're going to be better off getting into January."The NBA season typically tips off in October, with the NBA Finals culminating in June. However, the current 2019-2020 season was delayed for several months due to the COVID-19 pandemic, and the league is currently is still in the midst of the conference semifinals.In addition, Silver said Tuesday that it's the league's goal to play a standard 82-game season and playoffs in 2021."Further, the goal would be to play games in home arenas in front of fans, but there's still a lot we need to learn in terms of rapid testing, for example. Would that be a means of getting fans into our building? Will there be other protections?" Silver said.Upon restarting its season in July, the NBA opted to hold all games and board all players, coaches and team personnel at the ESPN Wide World of Sports Complex at Disney World. Players and coaches must remain at the resort at all times in order to be eligible to play. Only about two-thirds of teams continued play in the 2020-21 season, and a seeding round was conducted before the standard playoffs began.MLB and the NFL chose to play games in home stadiums with limited or no attendance upon the start of their seasons. Silver says he hopes to learn from those sports before making a final decision on the 2021 season."There's a lot of new information out there in the marketplace that we're looking to absorb. But the goal is to play a standard season," Silver said. 1835
