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) -- First responders in Carlsbad are prepared for any emergency, thanks to their state of the art training facility."This is how we become good," says Carlsbad Fire Captain Scott Tucker. "This is our hallowed ground where we get to spend all the time, make the mistakes here, so we don't make them out there."The Carlsbad Safety Training Center spans four acres. It includes a four-story live burn tower, a two-story home, and a main street replica. It also has two shooting ranges, classrooms, and computer simulation rooms.The parking lot can also be used for driving simulations and tests."It's realistic training," says Carlsbad Police Captain Peter Pascual. "The officers can utilize what they learn in the training environment, out in the field."The shooting ranges are adaptable, letting agencies set up different scenarios. They can even drive cars into the range. "It allows us to get in the right frame of mind in how to survive and solve these problems in the field," says Pascual. "We try to create scenarios that are realistic and functional for the success of the officers in the field.""It allows us to get a good foundation in training and build on stuff that we normally don't get to do," says Tucker.Facility Manager Jason Kennedy says the complex tries to stay as modern as possible, always adding more ways to train."We're always looking forward, cause training is so dynamic," says Kennedy. "We're trying to look forward at what things are emerging in the environment."The facility has become so popular, other state and federal agencies have rented the facility from Carlsbad for their own training events.This year, 28 different agencies from around California and the rest of the United States have booked time to train in Carlsbad. Hundreds have stopped by either for tours or training since it opened."It is movie-esque," says Tucker. "It's an amazing facility, and it is state of the art."To learn more about the facility, click here. 1993

CHICAGO — A special prosecutor in Chicago says Cook County State’s Attorney Kim Foxx and her office abused their discretion in the case against actor Jussie Smollett but did nothing criminal. In a statement on the conclusions of his investigation, special prosecutor Dan Webb sharply criticized the handling of the Smollett case by Foxx and her assistant prosecutors, saying their handling was marked by disarray and misleading statements.In his conclusion, Webb wrote that the investigation “did not develop evidence that would support any criminal charges against State’s Attorney Foxx or any individual working at (her office)” but “did develop evidence that establishes substantial abuses of discretion and operational failures”In March last year, Foxx’s office surprised and angered many in Chicago by dropping charges that accused the former “Empire” actor of staging a racist, homophobic attack against himself. Smollett is still adamant that the attack was real and wasn’t a publicity hoax.Foxx is seeking re-election in the fall. She won a primary election in March. 1083

  

CHICAGO, Ill. -- As coronavirus cases continue to spike, some states are reinstating restrictions on indoor dining. Restaurants already reeling with huge financial strains are trying to find innovative solutions to keep their doors open. Some are thinking outside the box and into a bubble.“What you're seeing in Washington D.C. and Chicago and elsewhere are local mayors trying to incentivize and help restaurants winterize their outdoor spaces and really doing whatever they can to encourage outdoor dining,” said Mike Whatley, vice president of state and local affairs for the National Restaurant Association.But with indoor dining shut down in many places across the country, geodesic domes or igloos, tents and mini greenhouses are popping up to help keep diners warm and safe.The National Restaurant Association says a recent survey indicates 49% of full-service restaurant operators say they are taking actions like installing tents or patio heaters to extend their outdoor dining season.Restaurant owner Sophie Huterstein and her staff built 14 4x6 greenhouses for use outside her restaurant, The Darling.“We’ve been utilizing this system of being able to dine together, apart from the moment we reopened after the initial shutdown, as a genuine intent to protect the guests and our staff,” she said.The idea was inspired by an installation in Amsterdam. Each one can accommodate two to four people and is helping sustain her business while indoor dining is restricted.“You are sitting closely in there, but it is our hope that no one would dine with people that they are not very familiar with,” said Huterstein.Safety experts say this type of seating can keep people safe if there’s frequent cleaning and ventilation.California resident Sarah Moffat dined inside a greenhouse for the first time.“I don't know if we're gonna have a sense of normalcy ever again,” said Moffat. “But to have moments that you can share with friends and your close loved ones in a safe environment is kind of amazing.”The City of Chicago challenged designers from across the country to propose winter dining solutions.Atlanta-based national design firm ASD/Sky created a modular cabin inspired by ice fishing huts that would fit inside the footprint of a parking space. Their goal was to create a reason to stay on-site instead of taking out.“People just want an experience that’s what we're lacking right now,” said ASD Sky Designer Nicole Grillet. “So that was the driver behind creating this idea.”Urban development designers Neil Reindel and Flo Mettetal were inspired by Legos with their "Block Party" concept. The compact, heated two-seater eat-in modules can be deployed and retracted.“Much like how you would previously push tables together, the idea would be that these frames of two could be connected in increments of two and you could have larger or smaller groups based on that,” said Reindel.It’s something they say could be utilized anywhere in the country.“It was really meant to be user friendly and kind of fit the needs of the restaurant wherever it is,” said Mettetal.With 40% of restaurant owners worried about staying in business through February, many are banking on futuristic dine-in concepts to help them brave the uncertain winter ahead. 3260
