SACRAMENTO, Cali. – If you’ve ever wanted to experience life beyond the Earth’s atmosphere, you may get the chance in six years. A company has a goal to make space vacations a reality by 2025. Right now, The Gateway Foundation is developing the very first space hotel with artificial gravity. “So the Von Braun Space Station is going to be the first commercial space station with artificial gravity,” said Tim Alatorre, a senior design architect with the company. The Von Braun Rotating Space Station will basically be a space hotel for customers.“So, the station works like a bike tire, we’re going to have spokes coming out of the central hub. That’s where the spaceships will dock, zero gravity and then it rotates,” said Alatorre. “So, the rotation creates that artificial gravity on the perimeter – this is where people will be living on the outside edge.”Although artificial gravity sounds like something out of science fiction, Alatorre says the science is sound. Designers will be using technology from the International Space Station.“NASA built the space station with just a few tools, one of them is the mechanical arm that we often see in the videos,” said John Blinko, President of the Gateway Foundation. “It’s the arm that we want to adopt in our space construction and designs and schemes and so forth.”But all of this depends on Elon Musk and SpaceX’s launch system. “SpaceX is developing the Super Heavy and the Starship platform. Our projections are showing the price of tickets is going to get lower as time goes on. So for right now, it could be cost prohibitive for some, but in a few short years, it’s going to be a common thing people do. As soon as Starship is ready to launch and is orbital, we want to be one of the first customers to launch into orbit.”In 2025, Alatorre says people will be able to vacation to space. “So, the space station is going to be a big draw to people,” said Alatorre. “We’re going to have a hotel, restaurant, bar, gymnasium.”But it’s more than that. The foundation says it’s the first step to advancing beyond the atmosphere.“But big picture – we’re trying to build out a space industry,” said Alatorre. “We want to have multiple stations in space – space tourism going to the moon, going to Mars, going to other space stations. And just from a humanity standpoint, having hundreds of people being able to go up to space and look back on Earth and just know we are sharing this little blue marble. I think it’s going to have a profound impact on people.” 2522

Rep. Steve King, the Iowa Republican who was stripped of his congressional committee assignments earlier this year, was not allowed to fly aboard Air Force One on Tuesday as President Donald Trump traveled to Iowa, two GOP officials say.King, who represents the state's 4th District in Western Iowa, asked the White House to join the President's entourage, but administration officials rejected the request, two officials familiar with the matter told CNN.Republican Sens. Joni Ernst of Iowa and Deb Fischer of Nebraska joined Trump aboard Air Force One. Ernst had not been planning to travel with the President, citing her voting schedule, but ended up flying to Iowa with Trump.King declined to comment about the snub, telling CNN on Wednesday morning that he had nothing to say about the matter.Instead of cruising back to Washington on Air Force One, King buckled himself into seat 1A and sipped a cup of coffee on an American Airlines flight back to the nation's capital.He attended the Republican Party of Iowa's fundraising dinner in West Des Moines on Tuesday evening. He faces a primary challenge in his re-election bid next year.While King has a history of making incendiary remarks around race and immigration, King was removed from his committee assignments and rebuked by members of his own party after giving an interview with The New York Times in January in which he made racist comments. In the article, King, as part of a defense of what he said was the "culture of America," asked how certain terms had become controversial in modern discourse."White nationalist, white supremacist, Western civilization — how did that language become offensive?" he told the Times. "Why did I sit in classes teaching me about the merits of our history and our civilization?"King said on the House floor in January that he rejected the ideology of white nationalism and he maintains that his comments were misinterpreted. The House Republican Steering Committee removed King from his committee posts shortly after the comments were publicized in January.Despite the controversy, King refused to step aside from his post in Congress and announced in February he'll run for re-election in 2020. He won his race in 2018 by 3.6 percentage points. 2256

Rick Brown walks through Kenai Fjords National Park to a place where climate change's impact is hard to miss. “The changes to us have been bang, bang, bang," Brown says. "Every year it’s a different year."As the years have gone on, the walk to Exit Glacier has become longer because it's melting away. Exit Glacier is one of the smaller glaciers in the park. It's popular with tourists because it's easy to get to. It's a short walk from where they park. Signs mark the path people take to get to the glacier; the dates on the signs range from the early 1900s to 2010. The signs mark where the glacier once was and where it's melted to. "If this doesn’t convince you that things are changing, then there is no use in trying to even convince you," Brown says.Brown owns Adventure 60 North. He takes people on tours and hikes around the glacier. It's a job in glacier tourism that often has him facing questions about climate change. "I tell them what I see, I don’t know the reason why it’s happening," he says. His answer isn't about politics but what's become the reality here."I don’t know if it's humans or nature or naturally caused. I think it’s both, and that's my opinion and I kind of leave it at that," Brown says."I've lived in Alaska for almost 50 years. Anyone who has lived here a long time has seen the weather change," says Doug Capra.Capra is a former park ranger and local historian in tiny Seward, Alaska. “We’ve seen winters come later, springs come earlier,” Capra says. For years, he's documented Alaska's changing climate and Exit Glacier's retreat.“My concern is the denial. I write history and I have great admiration for human ingenuity," Capra says. "Human beings have survived a lot of things. It’s the questions of how we’re going to do it. It’s a question of will."Rick knows some people can't be convinced of the impact climate change is having.“Some people come here with a view that they’ve adopted and they’re not going to change no matter what you tell them," Brown says. "So I don’t try. I’m the old guy out here, I know what I'm seeing."He says winters don't see the snow they did when he first became a guide in Alaska in the '90s. He no longer does snowshoeing and ice hiking tours in the winter because of the lack of snow.“It’s changed our business," he says. "I don’t know if it’s hurt it. I would say we’ve adapted. And as far as I know, the key to surviving here is adapting."Time may be running out for Exit Glacier. “I would say, probably, I don’t know ... there have been guesses of ten, five years?” he says.According to the United States Geological Survey, 68.7% earth's freshwater is kept in ice caps and glaciers, meaning their retreat isn't just an Alaskan concern or one Brown feels should be left for the future. "It's real folks," Brown says. "Change is happening. Regardless of what’s causing it. We need to get prepared to adapt to deal with the change." 2922

Randy Heiss wasn't going to let anything -- not even an international border -- stop him from fulfilling an 8-year-old girl's Christmas wishes.Heiss was hiking with his dog this month near Patagonia, Arizona, when he spotted something strange in the brush: the tattered remnants of a red balloon.At first he thought it was just some trash. But then he saw a note tied to it."I unfolded the note and I could see that it was in Spanish and written by a little girl," Heiss told 488
