CAPE CANAVERAL, Fla. (AP) — SpaceX's sleek, new crew capsule arrived at the International Space Station on Sunday, acing its second milestone in just over a day.No one was aboard the Dragon capsule launched Saturday on its first test flight, only an instrumented dummy. But that quickly changed once the hatch swung open and the space station astronauts floated inside."A new generation of space flight starts now with the arrival of @SpaceX's Crew Dragon to the @Space_Station," NASA Administrator Jim Bridenstine tweeted. "Congratulations to all for this historic achievement getting us closer to flying American Astronauts on American rockets."This beefed-up, redesigned Dragon is the first American-made, designed-for-crew spacecraft to pull up to the station in eight years. The next one coming up will have its own two-man crew.The space station's three astronauts had front-row seats as the white 27-foot-long (8-meter-long) capsule neatly docked, a little early no less. TV cameras on Dragon as well as the station provided stunning views of one another throughout the rendezvous.Just two hours after the Dragon's grand entrance, the station crew entered to take air samples. The astronauts wore oxygen masks and hoods until getting the all-clear.If the six-day demo goes well, SpaceX could launch two astronauts this summer under NASA's commercial crew program. Both astronauts — Doug Hurley and Bob Behnken — were at SpaceX Mission Control in Southern California, observing all the action. They rushed there from Florida after watching the Dragon rocket into orbit early Saturday from NASA's Kennedy Space Center."Just super excited to see it," Behnken said minutes after the link-up. "Just one more milestone that gets us ready for our flight coming up here."While SpaceX has sent plenty of cargo Dragons to the space station, crew Dragon is a different beast. It docked autonomously under the station astronauts' watchful eyes, instead of relying on the station's robot arm for berthing. The capsule's nose cap was wide open like a dragon's mouth, to expose the docking mechanism.Behnken said that's the way it should work when he and Hurley are on board; they may push a button or two and will have the ability to intervene, if necessary.As part of Sunday's shakedown, the station astronauts sent commands for the Dragon to retreat and then move forward again, before the capsule closed in for good.SpaceX employees at company headquarters in Hawthorne, California, cheered and applauded as crew Dragon pulled up and docked at the orbiting lab, nearly 260 miles (400 kilometers) above the Pacific, north of New Zealand. They burst into applause again, several minutes later, when the Dragon's latches were tightly secured.The capsule's lone passenger for launch — a mannequin wearing a white SpaceX spacesuit — remained strapped into its seat as the station's U.S., Canadian and Russian crew removed supplies and photographed the spotless white interior. The test dummy — or Smarty as SpaceX likes to call it, given all the instrumentation — is named Ripley after the lead character in the science-fiction "Alien" films.Dragon will remain at the space station until Friday, when it undocks and aims for a splashdown in the Atlantic, a couple hundred miles off the Florida coast.Like Ripley, the capsule is rigged with sensors to measure noise, vibration and stresses, and to monitor the life-support, propulsion and other critical systems throughout the flight.SpaceX aims to launch Behnken and Hurley as early as July.Next up, though, should be Boeing, NASA's other commercial crew provider. Boeing is looking to launch its Starliner capsule without a crew as early as April and with a crew possibly in August.NASA is paying the two private companies billion to build and operate the capsules for ferrying astronauts to and from the space station. Astronauts have been stuck riding Russian rockets ever since NASA's space shuttle program ended in 2011. Russian Soyuz seats go for up to million apiece. 4030

CARLSBAD, Calif. (KGTV) - A burglary victim is making a plea for the return of a priceless family heirloom after thieves forced open her front door and raided her Carlsbad home. Joanna Bradford returned home last Thursday and saw her front door open and damaged. "My heart started beating, immediately nervous and called police," said Bradford.Bradford eventually discovered a ransacked bathroom and bedroom. A new iPad and some jewelry had been stolen, including a gold-and-silver Omega watch belonging to her father, who passed away in 2013. He bought it in the 70s and wore it to work every day."I would put it on, look down, and see my dad. He was with me whenever I was wearing it," said Bradford.Bradford's Ring doorbell camera revealed clues about who made that watch vanish.Just before 10:30 a.m., a man wearing a blue shirt and sunglasses rings the doorbell with his knuckle. He then leaves and comes back with a backpack. That's when the motion-activated camera stops.In the next video, that man and another man are seen emerging from the home with backpacks, before getting into a vehicle, possibly a light-colored GMC Acadia SUV, and driving off. Another vehicle, possibly a light-colored Audi A2 Hatchback, leaves at the same time. "They knew what they were doing. They've done this before, and they will absolutely do it again," said Bradford.If you recognize the men in the video, you're asked to call Carlsbad Police at 760-931-2197. 1458

  

CAPE CANAVERAL, Fla. (AP) — The first astronauts to ride a SpaceX capsule into orbit are headed toward a splashdown Sunday in the Gulf of Mexico to close out their two-month test flight.It will be the first splashdown in 45 years for NASA astronauts and the first return in the gulf. Florida's Atlantic coast is starting to see the effects of Tropical Storm Isaias. But waves and wind are calm near Pensacola in the Florida Panhandle.Test pilots Doug Hurley and Bob Behnken departed the International Space Station on Saturday night. They awoke to a recording of their young children urging them to “rise and shine.” 624
