A Japanese space probe has successfully fired a "bullet" into an asteroid as part of a mission to collect rock samples from the celestial body.The projectile disturbed material from the exterior of asteroid Ryugu which then floated from its surface due to the weak gravitational field.These particles were successfully collected by the probe, according to Japan's space agency JAXA, which announced that the Hayabusa 2 craft had successfully touched down on on the asteroid on Friday morning Japanese time.JAXA scientists had expected to find a powdery surface on Ryugu, but tests showed that the asteroid is covered in larger gravel.As a result the team had to carry out a simulation to test whether the projectile would be capable of disturbing enough material to be collected by what scientists call a "sample horn," which protrudes from the underside of the probe.This video shows the success of a December 28 test, which green-lit the asteroid landing.The team is planning a total of three sampling events over the next few weeks.Hayabusa 2 will depart Ryugu in December 2019 and return to Earth by the end of 2020 with its precious cargo of samples, which will be analyzed by scientists such as John Bridges, a professor of planetary science at the University of Leicester, UK.Bridges, who was also involved in the first Hayabusa mission, told CNN via telephone on Thursday that the event was "nail-biting stuff" due to the extreme precision involved in landing on Ryugu."This is a significant mission," said Bridges. "Sample return missions are particularly exciting."He told CNN that the Hayabusa 2 mission is interesting because Ryugu is a C-class asteroid which humans haven't visited before."One thing I'm pretty sure of is that it will throw up some unexpected results," said Bridges, who believes that information from Ryugu samples could make us think again about the early evolution of the solar system.Beneath their desolate surface, asteroids are believed to contain a rich treasure trove of information about the formation of the solar system billions of years ago.C-type asteroids, which are largely composed of carbon, are the most common variety of asteroids, comprising more than 75% of those currently discovered. The other two main types of asteroid are the metallic S- and M-types, according to NASA.Ryugu is expected to be "rich in water and organic materials," allowing scientists to "clarify interactions between the building blocks of Earth and the evolution of its oceans and life, thereby developing solar system science," JAXA said.If Hayabusa 2 makes it back to Earth on schedule it will be the first mission to bring back samples from a C-class asteroid.JAXA scientists are currently racing NASA for that historic achievement, with the US agency's own sample retrieval mission due to arrive back on Earth in 2023.Even reaching the asteroid is a massive achievement as it is the equivalent of hitting a 6-centimeter (2.4-inch) target from 20,000 kilometers (12,400 miles) away."In other words, arriving at Ryugu is the same as aiming at a 6-centimeter target in Brazil from Japan," said JAXA.The-CNN-Wire? & ? 2019 Cable News Network, Inc., a Time Warner Company.

A judge ordered President Donald Trump to pay million to a collection of nonprofit organizations as part of a settlement with the New York state attorney general's office to resolve a civil lawsuit that alleged "persistent" violations of charities law that included unlawful coordination with the 2016 Trump presidential campaign, according to a court filing Thursday.Filed in June 2018, the lawsuit alleged that the President and his three eldest children -- Don Jr., Ivanka and Eric -- violated federal and state campaign finance laws and abused the Donald J. Trump Foundation's tax-exempt status. According to the lawsuit, the Trumps allowed the foundation to be used "as little more than a checkbook to serve Mr. Trump's business and political interests."The settlement comes in the wake of an agreement by the foundation in December to dissolve under judicial supervision.Attorneys for the charity had said that "all of the money raised by the Foundation went to charitable causes to assist those most in need," and accused the attorney general's office of political motivation, citing campaign trail comments made by Attorney General Letitia James, who took office in January.Trump himself had vowed to fight the lawsuit, 1243

A 16-year-old white high school student is in custody after her plan to attack an historically black church in Gainesville, Georgia, with knives was foiled, police said Tuesday.The Gainesville High School student had been planning the attack at Bethel African Methodist Episcopal Church for several weeks, police said.She took significant steps, including researching black churches online and visiting Bethel AME once this month, police Chief Jay Parrish said. No one was at the church at the time, he said.A student overheard the teenager talking about the alleged threat on Friday and alerted a school administrator, who in turn notified a school resource officer, Parrish said.The teenager was taken into custody. She faces a charge of criminal attempt to commit murder, police said. "I have no doubt that we thwarted an attack that would've been ugly," Parrish said.Sgt. Kevin Holbrook with Gainesville police said he is not aware of the teen having an attorney.The teenager targeted Bethel AME because of its African American congregants and small congregation, the police chief said."I do know that she did a lot of internet research on what she wanted to do," Parrish said. "I think she wanted notoriety and in that she looked up African American churches."He said that even though there are several black churches in Gainesville, "somehow it landed her on this one and that became the target."Parrish said the teenager had written down how she planned to carry out the alleged plot and collected knives."She is a racist," the chief said, adding he wouldn't make the statement without "substantial evidence."He said the details he read about the alleged plot were "very sickening."The chief said it was "divine intervention" that no one was at the church when the teenager visited. He believes she had the knives with her.Police believe the girl acted alone. No other churches are at risk, Parrish said.Parrish said he called Bethel AME's pastor Friday afternoon after learning of the alleged plot.'It's sad that there is still hatred in the world'Shana Ramsey, a Bethel AME trustee, said she "could hear the hurt in her voice" when the pastor told her about the alleged plot Friday night."It's sad that there is still hatred in the world," Ramsey, 49, said shaking her head as she stood in the sanctuary."Because some are brought up to love everybody and that's what we would want the world to do, is to love everybody and to get along," said Ramsey.Members said they have spoken to the police chief about adding extra security.Started more than a century ago, the predominantly black church has more than 40 members, congregants said.Church members said Wednesday's Bible study was likely canceled, but they still planned to worship on Sunday."We hold steady to our faith. And we will be here on Sunday morning to worship with our fellow members and to get our praise on with the Lord," Ramsey said.'This is not a representation of us'School Superintendent Jeremy Williams said: "A single act by a student does not represent the views and beliefs of Gainesville City School System.""As a school system that celebrates our diversity, we are beyond stunned with the recent development. However, we are extremely proud of our students notifying school administration of a possible off-campus threat," he said.The teenager's plans were very detailed, the chief said."I'm highly alarmed that someone would feel that way and that would take these significant steps to attack an innocent person, a godly person, at a church, one of the most sacred things our society has left," Parrish said.Parrish, a Gainesville native, said the alleged plot is "the opposite of who we are.""I've been in this community my whole life and this is not a representation of us," he said. 3783

A civil lawsuit brought by the young man who has accused actor Kevin Spacey of sexual assault has been dropped, just over a week after it was filed, according to a new court filing.Spacey's accuser, who was an 18-year-old busboy at a Nantucket bar at the time of the alleged assault, filed the civil complaint on June 26. In it, the accuser said Spacey bought him "multiple alcoholic beverages" before he then forcibly touched and fondled his genitals -- the same allegations he made in an ongoing criminal case.The accuser's attorney, Mitchell Garabedian, told CNN via email Friday that he and his client voluntarily dropped the lawsuit and that he would have no further comment.Spacey, 59, faces criminal charges of indecent assault and battery in connection to the same alleged July 2016 incident. The former "House of Cards" star has pleaded not guilty.The civil lawsuit accused Spacey of explicit sexual behavior and infliction of mental distress. It demanded judgment in an amount to be determine by a jury, including costs, interests and attorney fees.The criminal case against Spacey will continue with a hearing scheduled for Monday.CNN is not naming the accuser because he is an alleged victim of sexual assault. 1234
