NASA has long been able to check out Mars on the ground with rovers and landers and from far above with orbital spacecraft. Now, it wants to prove that it can sustainably fly around the planet's thin atmosphere at low altitude -- with a tiny helicopter.NASA announced Friday it will send the Mars Helicopter to the Red Planet with the previously announced Mars 2020 rover, set to launch in two years from Florida.The hope is that aircraft like this one -- flying mechanical scouts -- will eventually give scientists another vantage point from which to observe Mars.The helicopter will be mankind's first attempt to fly a heavier-than-air craft -- think helicopter or airplane -- in an atmosphere other than Earth's, the space agency said.Its mission will be to take five test flights after it lands with the rover in February 2021. 839

More than 100 people die from opioid overdoses every day. Amid the opioid crisis, a newly FDA-approved opioid called Dsuvia could soon be hitting the market, and it’s said to be more powerful than morphine and fentanyl.Dsuvia was designed, in part, to help soldiers on the battlefield.For Navy veteran Rich Shock, a back injury turned out to be far worse than anything he experienced in Iraq and Iran. “At first, started with Vicodin and then it became Norco, and then they doubled the dose of Norco, and then it became Norco with Oxycontin,” describes Shock of his prescribed medication.  As his tolerance and dosage got higher, he started doctor shopping until they cut him off. That's when a friend offered him heroin. “He's like, ‘I'm telling you. It's cheaper. It's easier to find and it lasts longer.’ And he was right. He was absolutely right,” says Shock. The addiction cost him everything, including his job, his family and his home. He said he had one thought.  “How did I get this bad? Like, how did I end up here? After everything. You know I have a wife and a family and a good job,” Shock says. Veterans are twice as likely to suffer from opioid addiction, according to a United States Department of Veterans Affairs health system study. That's one reason behind the outrage over the FDA’s approval of the new, powerful painkiller.Dsuvia is 1,000 times more potent than morphine and 10 times more than fentanyl. It's restricted for use only in battlefields and emergency rooms for patients suffering tremendous pain from traumatic injuries.Even still, the chairman of the committee that reviewed the drug, did not want it approved for fears it will be abused. “I think that this the approval of this drug represents a failure of their most fundamental duties, and I think the veterans are [going to] pay for it with their lives,” says Brenton Huston, with Volunteers of America Veteran Support and Services. Hutson is a Marine who works with veterans.“There are already other drugs out there, less addictive, less potent that are also taken that way,” Hutson says. “So, there's really just no need for it.”Shock fought his way out of addiction, but he fears what could happen with a much more powerful drug. “With the opiate problem we have right now, why would you want to manufacture a drug that stronger? It doesn't make any sense to me,” Shock says. To help prevent abuse, the FDA is putting tight restrictions on Dsuvia. It won't be sold in retail pharmacies or be available for outpatient use, and it cannot be used for more than 72 hours. 2632

More than two dozen children in Virginia who had been reported missing are now recovered.The U.S. Marshals released a statement Monday morning stating their five-day effort called “Operation Find Our Children” resulted in the recovery of 27 children who had been previously missing in Virginia. They also located an additional six children who had been reported missing but were discovered with their legal guardians.More than 60 law enforcement officers from federal agencies, state and local regions participated in the effort. They were joined by 50 employees from social services, a team of medical professionals and representatives from the National Center for Missing and Exploited Children.Details about the children who were recovered, including when they were reported missing and where they were found, were not immediately available.This recovery effort is the latest from the U.S. Marshals. In September, a similar group of federal, state and local officers recovered 35 previously reported missing children in Ohio. And in Indiana, 8 kids were recovered in a similar missing kid law enforcement effort. 1123

MIRAMAR, Calif. (KGTV) - A plaque honoring Marines killed in a military training crash that happened 50 years ago at MCAS El Toro was unveiled at MCAS Miramar Wednesday."Knowing answers has really allowed us to come together," the granddaughter of Maj. Walter Zytkewicz, who was in the crash, said tearfully.Dozens of family members traveled to MCAS Miramar, where the squadron now resides, for the dedication.Pati Davis Ruane traveled from Georgia and still remembers the crash."I was 7 years old and we lived on base at El Toro, we saw the black smoke, playing around outside and was like, 'Hey mom look!' and she was like, 'Oh it's just the crash crew practicing,'" Ruane said. It wasn't the crash crew. A C-130 was completing touch-and-go practices and crashed violently, ultimately killing four of the five Marines on board.Her father, K.C. Davis, was the only one who saw his kids grow up, "I remember my mom going to three funerals in one day."This journey started in January 2019. Johnathan Keene often visited his cousin's grave at Arlington National Cemetery."I go up to visit him twice a year, typically Memorial Day and Veteran's Day," said Davis. Keene was in the neighborhood, Jan. 15, on his way to pick up his wife from the airport, and noticed Zytkewicz's grave next to the grave of his cousin, Capt. Robert Walls. Zytkewicz was in the Marines, like his cousin, and died the day before Walls. He said that "grabbed" him.Up until that day, Keene knew his cousin died in a military crash, but it wasn't spoken of at the dinner table. He knew there must be a connection to the two men, so he started digging. He found three other Marines were on the same training flight July 30, 1970: Staff Sgt. Kenneth Davis, 1st Lt. Roger W. Mullins, and Cpl. Kenneth Metzdorf."Major Zytkewicz was two months away from retiring," Keene said, adding that Zytkewicz was studying to become a realtor.Keene said Metzdorf wasn't supposed to be on the flight but, "called his best friend and said 'hey could you go on this flight for me today?' So they switched and that cost him [his life]."Keene tracked down the redacted incident report and filled in the gaps with interviews from witnesses and Marines who knew the men on board."Witnesses say they waited too late to pull the plane out of the angle of attack and the plane hit, bounced, flipped upside down, hit again, bounced in the air, the left wing fell off, all four props fell off. The plane landed right in the middle of the air field. Flames and fuel streamed down the runway, they said it was basically a long stream of fuel and fire," he said.Keene was amazed to learn his cousin and Metzdorf walked through the flames following the crash, "the report listed 80 percent - 90 percent coverage of third degree burns. I can't even imagine how he walked out," he said.Mullins was killed on impact, found 50 yards from the plane with a broken leg. Walls, Zytkewicz and Metzdorf died days later from their injuries. Keene said Walls died from burns in his lungs.Davis passed away in 2013.The exact cause was redacted in the report but Keene believes the Marine Corps wants to preserve the honor of the pilot and protect his family."After the crash, the material that made up Marine Corps and Navy flight suits was changed. They thought it was a flame retardant material, unfortunately it burned and melted to their skin," he said.Keene hopes these difficult discoveries will fuel Marines' admiration. To keep their memories alive, Keene created a plaque with the team's names. The plaque sits on the wall just inside the entrance to the squadron's historical room."Every other Marine that goes through that squadron will see that plaque and realize there's five men that in some way or another touched their lives from either a safety stand-point or history and lineology of VMGR-352," Keene said. 3858
