This summer marks the 50th anniversary of the Apollo 11 Moon landing. While the astronauts were the stars of the show, the flight controllers back in Houston has a supporting role. The Apollo 11 Mission Control Center at NASA was a historical landmark, but it wasn’t being treated as so.Four years ago, NASA chose Sonya Yungeberg and her team at Ayuda Companies to lead the restoration of the Mission Control Center.“We have been working on this project pretty diligently, starting at the research phase for about three years now,” Yungeberg says.The control center hadn’t been used since the 90’s and needed a lot of work. A team of over 100 people began restoring 50 years of history. Month after month, they sifted through photos, film and artifacts.“As you can imagine, when people go and take pictures or video, they are not looking at the stuff on the desk or under the desk,” she says.To recreate the past, they needed to go on the hunt for items that were no longer made, including old ash trays, coffee mugs, headsets and so much more. They spent months on eBay to find old replicas of the items. One huge component of the room they didn’t have to search for were the original consoles used by the flight controllers, like Director Gene Kranz.“Mr. Kranz came in one day and had been doing interviews and he turns and says, ‘Where’s my foot pedal?’ And all of us stood there dumbfounded for a second like, ‘Oh, there is a foot pedal,’ and so we went to find foot pedals,” recalls Jennie Keys with Ayuda Companies.One of their greatest accomplishments were the renderings on the big screen. “These were not available. They were not original,” Yungeberg says. “We had to recreate them and the detail in them from looking at footage, again frame by frame.”Attention to detail was mission critical. From uncovering the numbers on the walls, scraping the gum off all the chairs, matching the carpet that doesn’t exist anymore and even having the same bouquet of roses that were in the room for every launch. For the items they couldn’t track down, the team used a 3D printer to make them. After three years, the project was complete.“The plan was to have it open by the anniversary of the Moon landing, and we barely made it,” Yungeberg says.The seal of approval came from the original flight controllers who were over the moon about seeing the massive fragment of space history restored.“Gene Krantz said he didn’t quite cry, but he got a rush of emotion and he really, really loved it,” Yungeberg says.NASA congratulated the accomplishment by saying, “This is what happens when American’s come together and work hard.” 2635

The RMS Titanic was visited by divers for the first time in 14 years, and the ship that was once a picture of luxury was found in the process of being swallowed up by the ocean floor and ravaged by metal-eating bacteria.A series of five dives were completed this month by an exploration team from Triton Submarines to the spot 370 miles south of Newfoundland, Canada, and 4,000 meters below the surface where the ship deemed "unsinkable" now rests, according to a release from 489

This week's series of earthquakes served as a reminder that the United States' earthquake risk extends far beyond the Pacific Coast. On Tuesday, Puerto Rico was rocked by a 6.4 magnitude earthquake. The earthquake knocked out power to most of the island, killing at least one. Also in recent days, minor earthquakes were felt in Tennessee and Texas. While there have been dozens of earthquakes with a 4.5 magnitude or higher throughout the United States in recent years, the eastern United States see relatively fewer. Only four earthquakes of 4.5 magnitude or greater in the last four years have impacted the eastern United States. But the issue is not the quantity of earthquakes in the eastern United States, but the impact. The USGS puts out a hazard map that shows the earthquake risk nationwide. The map shows areas such as the Pacific Coast and parts of Alaska and Hawaii with a high risk of peak ground accelerations. It turns out that areas of Missouri, Tennessee, Kentucky, Arkansas, Illinois and South Carolina.USGS scientist David Schwartz agrees that the Pacific Northwest all the way to Charleston, S.C., practically every region of the United States, has a risk of feeling a devastating earthquake."The nature of the crust changes as you go from east to west. The Central and Eastern US, the crust is really old, it is older it is colder, it is denser, than the crust in the west which is younger,” Schwartz said. “It’s broken up by many faults and warmer. These different crusts transmit seismic waves differently.”And this difference in geology means that a strong earthquake in the Eastern United States could cause damage over an extensive area.Although the Eastern United States has not had many major earthquakes in the last century, two of the most powerful quakes in American history have happened east of the Rockies. The magnitude 5.8 earthquake that caused damage to the Washington Monument in 2011 is only a minor example of the kind of earthquakes the Eastern United States could see.In 1811 and 1812, a series of earthquakes struck the Mississippi River valley along the New Madrid fault. The strongest of the quakes was a possible magnitude 7.8. The quake was felt across much of the Eastern United States.In 1866, a magnitude 7.0 rattled Charleston, S.C.“A repeat of any of those earthquakes would be extremely damaging, because the housing stock in the Central and Eastern U.S. has not been designed for earthquakes,” Schwartz said.According to a survey funded by the U.S. Army, a magnitude 7.7 earthquake located along the New Madrid fault could cause 85,900 deaths and 8 billion in damage. By comparison, Hurricane Katrina caused roughly 1,500 deaths and 0 billion in damage.What to do during an earthquakeDROP to the ground (before the earthquake drops you!),Take COVER by getting under a sturdy desk or table, andHOLD ON to it until the shaking stops. 2906

  

The Trump administration on Wednesday will announce two executive orders aimed at freeing up more pipelines to supply the United States with oil and gas. The orders could give the federal government more power over states in approving energy projects.The United States is producing more oil and gas than any point in its history, in large part because of the shale boom in the Permian Basin in West Texas. But producers have trouble getting all of that supply to customers due to constraints on the number of pipelines.Canadian oil is also a problem, because Canada has run out of pipelines to send oil to the United States.Several states have invoked the Clean Water Act to delay approval of sections of pipelines, arguing that the pipelines will cause environmental damage.New York, for example, rejected a natural gas pipeline three years ago that state officials said failed to meet water quality standards. Developers still want to build that pipeline, which was supposed to transport natural gas throughout markets in the Northeast.One of the executive orders will direct the Environmental Protection Agency to revise the way states can consider the Clean Water Act when deciding whether to approve pipelines, according to a senior administration official.The official told reporters Tuesday night that there are "a lot of problems" with the way the Clean Water Act is being interpreted, adding that the administration expects the executive order to "alleviate" some of those issues.A second executive order is aimed at making cross-border energy infrastructure approval more streamlined. It says that any decision to issue or deny a cross-border permit shall be made solely by President Donald Trump.That executive order isn't limited to pipelines, but would cover other kinds of energy infrastructure projects, too. It comes amid controversy over the Keystone XL Pipeline, which is operated by TransCanada and which would bring Canadian oil into the United States. The Obama administration opted to shut down that pipeline, but the Trump administration has sought to reopen it. An official said Tuesday that the new executive order would affect "future" permitting for energy projects at the border.As energy prices have risen over the past several months, Trump has called on OPEC, the oil cartel led by Saudi Arabia, to help reduce the price of oil in the United States. Oil prices have risen because of a variety of factors including fighting in Libya, sanctions against Venezuela and Iran, and the inability of United States energy producers to deliver their vast supply to US customers.It is unclear if the executive order will have its intended, if any, impact. Many states are embroiled in bitter legal disputes with the Trump administration, and the executive order is unlikely to settle any of those disputes. 2838

  

This year’s Memorial Day weekend at Lake of the Ozarks businesses was “busier than any year,” according to one proprietor.Robin's Resort owner Bill Morgan said that most people at his business “were practicing social distancing,” though the size of the crowds – including those seen in a viral video that circulated over the weekend – were not surprising."What you saw in that video is the norm for those types of places even without what's going on now,” Morgan said.Local health experts, however, see large gatherings as a concern as phased reopenings are underway. They said activities seen in videos from the Lake of the Ozarks are risky, even if you're healthy."Those large groups with strangers, you may never have contact with someone again and know if they get symptoms in a couple of days,” Dr. Sarah Boyd, an infectious disease physician at St. Luke's Health System, said. “Those things all just increase that risk of spread to other parts of our communities.”Experts like Ray Dlugolecki, of the Jackson County Health Department, stressed the need to take proper precautions for oneself and neighbors."It would be disastrous to move backwards because we can't take part in sensible precautions like mask wearing, social distancing, hand washing," Dlugolecki said.Larry Giampa, owner of Blondies Burger Bar, is concerned about those crowds."I'm worried about the virus,” he said. “I'm 68. My wife is 66. And what worried me is all the Chicago, St. Louis and Kansas City and other areas that came in this weekend. I'm worried about it. I'm worried for my employees getting sick."The Camden County Sheriff's Office released a statement on Monday, that said "social distancing is not a crime and there the sheriff's office has no authority to enforce." It also said that the sheriff’s office hopes visitors "exhibit personal responsibility when at the lake.This article was written by Dan Cohen for 1917
