Rascal Flatts is bowing out with a bang. The most awarded country group of the last decade announced Tuesday that they’ll mark their 20th anniversary with a 25-city farewell tour this year.The "Rascal Flatts Farewell: Life is a Highway Tour" will kick off in Indianapolis on June 11, stretch coast to coast, and end in West Palm Beach on Oct. 17. During the tour, lead singer Gary LeVox, bassist Jay DeMarcus and guitarist Joe Don Rooney say they’ll reflect with fans on their catalogue of hits like “Bless The Broken Road,” “My Wish,” and “What Hurts The Most.” DeMarcus told CBS This Morning that the band is looking forward to spending the entire year loving on fans and thanking them for their amazing career over the last 20 years. “While it is of course bittersweet, it is so important to us to celebrate what our music has meant to their lives, as well as what the fans have meant to us," DeMarcus said. "There is no sadness here, just new chapters, new journeys, and new beginnings. Rascal Flatts’ music will live on forever, because of our fans, and this year is all about them!” 1100

Residents in Freeport, Grand Bahamas woke up to severely flooded neighborhoods on Tuesday following the devastation left by Hurricane Dorian. United Nations officials estimate more than 60,000 people in the northwest Bahamas will need food following the catastrophic natural disaster. Tim Aylen, a Bahamian journalist assisting The Associated Press with the hurricane coverage, had to abandon his home with his family due to the flooding. Speaking about some of his work, Aylen said he had no idea he would be shooting pictures of himself and his family evacuating their home as part of his coverage. Early Tuesday, Aylen could be seen wadding through chest-level flood waters as he made his way through the streets of Arden Forest in Freeport.His 21-year-old daughter Julia Aylen, and 17-year-old son Matthew Aylen, along with their three dogs were seeking higher ground Tuesday morning, with images showing their exhaustion from the ordeal. A spokesman for the International Federation of Red Cross and Red Crescent Societies said Tuesday about 45% of homes in Grand Bahama and Abaco were severely damaged or destroyed.The organization was aiming help 20,000 of the most vulnerable people, including a large Haitian community, the spokesman said. 1260

  

SpaceX completed the last big test of its crew capsule before launching astronauts in the next few months, mimicking an emergency escape shortly after liftoff Sunday.No one was aboard for the wild ride in the skies above Cape Canaveral, just two mannequins. The nine-minute flight ended with the Dragon crew capsule parachuting safely into the Atlantic, after separating and speeding away from the exploding rocket.“I’m super fired up,” Elon Musk, the company’s founder and chief executive, told reporters. “It’s just going to be wonderful to get astronauts back into orbit from American soil after almost a decade of not being able to do so. That’s just super exciting.”NASA astronauts have not launched from the U.S. since the space shuttle program ended in 2011. Musk and NASA Administrator Jim Bridenstine said the next Crew Dragon could launch with a pair of NASA astronauts in the second quarter of this year — as early as April.The Falcon 9 rocket blasted off as normal, but just over a minute into its supersonic flight, the Dragon crew capsule catapulted off the top 12 miles (20 kilometers) above the Atlantic. Powerful thrusters on the capsule propelled it up and out of harm’s way, as the rocket engines deliberately shut down and the booster tumbled out of control and exploded in a giant fireball. The capsule reached an altitude of about 27 miles (44 kilometers) before parachuting into the ocean just offshore to bring the test flight to a close. Everything appeared to go well despite the choppy seas and overcast skies. Within minutes, a recovery ship was alongside the capsule.Recycled from three previous launches, the SpaceX rocket was destroyed as it burst apart in flight and slammed in pieces into the sea. SpaceX normally tries to recover its boosters to drive down launch costs, landing them upright on a floating platform or back at the launch site.NASA’s commercial crew program manager, Kathy Lueders, said the launch abort test was “our last open milestone” before allowing SpaceX to launch Doug Hurley and Robert Behnken to the International Space Station. Their launch date will depend, in part, on whether NASA decides to keep them for months at the orbiting lab, versus just a week or two. A longer mission will require more training before flight.The astronauts monitored Sunday’s flight from the firing room. Hurley said it was “pretty neat to see” the capsule aboard the recovery ship within two hours. By all early accounts, the test was successful.“We’ll see what the data show and go from there,” Hurley said. “But it certainly is a confidence builder from the standpoint if you ever got into that situation, that Dragon can get us away from the booster quickly.”The astronauts also will have access to speed before liftoff. During a launch dress rehearsal Friday, Hurley and Behnken rode in a white Tesla Model X from Kennedy Space Center’s crew quarters to the launch pad, their sleek white and black spacesuits matching the electric sports car with wing-like doors. Musk, who also runs Tesla, used the cars to get around the space center Sunday.Delayed a day by bad weather, Sunday’s launch from Kennedy brought together hundreds of SpaceX, NASA and Air Force employees on land, at sea and in the air. Tourists and locals alike packed the adjoining visitor complex and nearby beaches to see the dramatic fiery spectacle of an out-of-control rocket. Musk brought along his own family, including his brother.NASA hired SpaceX and Boeing a decade ago to transport astronauts to and from the space station for billions of dollars. Both companies struggled with technical problems, adding years of delay and forcing NASA to shell out hundreds of millions of dollars extra for Russian rocket rides.After multiple cargo deliveries for NASA, SpaceX successfully flew an enhanced crew capsule to the space station last March without anyone on board, but it exploded a month later during ground testing. The emergency escape thrusters — the kind used in Sunday’s test — had to be retooled. In all, SpaceX has tested these powerful Super Draco thrusters some 700 times.Last month, meanwhile, Boeing’s Starliner crew capsule ended up in the wrong orbit on its first test flight and had to skip the space station. The previous month, only two of the Starliner’s three parachutes deployed during a launch abort test.Lueders said it’s too soon to know whether Boeing will need to send another Starliner to the space station without a crew or go straight to launching astronauts later this year. An investigation team is still looking into why the Starliner’s automated timer was off by 11 hours during the December test flight.The importance of launch escape was demonstrated in 2017 when two astronauts, an American and a Russian, were pulled to safety during a failed launch from Kazakhstan. They experienced up to seven times the force of gravity during the abort, but walked away from the accident.The SpaceX in-flight abort system, Musk pointed out, should be gentler for the crew and is good from the launch pad all the way to orbit.Musk said the Dragon’s escape system should work — in principle — even if the capsule is still attached when the rocket erupts in a fireball. He said that could look like “something out of ‘Star Wars’” with the capsule flying right out of a fireball.“Obviously we want to avoid doing that,” he quickly added, taking note of all the NASA personnel around him.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.
