Perfect score not enough on ‘Dancing’

first_imgBut in a second dance, he earned a score of just 28, bringing his total score for the week to 58. Even though it was just two points less than perfect, it was the lowest of the week. Judges’ scores are combined with viewer votes to determine which couple is eliminated. The three remaining celebrity dancers – Laila Ali, Joey Fatone and Apolo Anton Ohno – will begin the competition’s final round on Monday, when they will perform a dance chosen by the judges as well as a freestyle dance. The new “Dancing With the Stars” champion will be named on May 22. – Asssociated Press He earned a perfect score and glowing praise from the judges. But that wasn’t enough to keep Ian Ziering on “Dancing With the Stars.” The 43-year-old actor was booted from the ABC dance-off Tuesday during the competition’s semifinal round. “We’re in it to win it,” the “Beverly Hills 90210” alumnus said before his performance Monday. “This week you’re going to see a whole new Ian Ziering on the dance floor.” Judge Len Goodman seemed to think so, praising Ziering’s tango as “your best dance ever” and calling him “technically … the soundest of all the celebrity dancers.” He earned a perfect score of 30. 160Want local news?Sign up for the Localist and stay informed Something went wrong.

Musk Says Falcon Heavy Rocket Might Explode During First Flight

first_img Elon Musk’s Cheeky ‘Nuke Mars!’ Post Is Taking Over TwitterTesla EV Catches Fire After Colliding With Tow Truck in Moscow Stay on target Space travel ain’t easy, and SpaceX CEO Elon Musk knows it. Last year one of SpaceX’s rockets exploded on the launch pad causing damage that has left the company struggling to catch up on its orders. Soon the company will finally launch its ultra-heavy rocket, the Falcon Heavy. It’ll be the largest, most powerful rocket since the Saturn V ferried astronauts to the Moon in the 60s and 70s, and Musk thinks its maiden voyage will be a disaster, possibly repeating last year’s fiasco.“I hope it makes it far enough away from the pad that it does not cause pad damage. I would consider even that a win, to be honest,” Musk told NASA International Space Station program manager Kirk Shireman. “Major pucker factor, really; that’s, like, the only way to describe it.”Musk and Shireman spoke at the 2017 International Space Station Research and Development conference in DC just yesterday. The summit was a who’s who of advanced space and aeronautics research and engineering, but Musk, as he is wont to do, stole the show with talk of the Falcon Heavy, but not without reason.The US currently lacks a heavy-duty rocket, and Space X has had a bunch of spectacular wins recently. That has everyone buzzing with talk of the Falcon Heavy, because it will be the first vehicle since the Saturn V capable of carrying an astronaut to the Moon or even Mars. But Musk doesn’t want people jumping the gun. There’s a lot of technical hurdles his team had to address, and there’s plenty more testing it needs before people will be able to ride along.Falcon Heavy’s problem is a simple one, and it stems from Musk’s push to make space flight cheap and accessible — this rocket is basically just three Falcon 9s strapped together. But, obviously, that rocket wasn’t designed to work in tandem with others, so Musk and the team at SpaceX had to re-engineer the structure of the central column to support the additional weight and vibration. Not to mention account for extra drag, etc.All that means that the Falcon heavy loses a little bit of its theoretical maximum thrust, dropping it from 67 metric tons to 63.8.“At first, it sounds really easy: Just stick two first stages on as strap-on boosters. How hard can that be?” Musk said. “But then everything changes. All the loads change, aerodynamics change, you’ve tripled the vibration and acoustics… We had to redesign the whole center-core airframe. It’s not like the Falcon 9, because it’s got to take so much load.”Musk says that the engineering behind the new rocket was extensive, and given how much of the machine the team hasn’t been able to test in the lab, that a failure, crash, or explosion is likely. He promises that no matter what, the first mission will be “exciting.”There’s no official launch date set, but it’s likely to be early fall.Let us know what you like about Geek by taking our survey.last_img read more
