When NASA created the first space missions, they knew astronauts flying on the Mercury and Apollo missions would need special suits. Most of the men were Air Force test pilots. And fittingly, the suits were upgrades of Navy flight suits for high altitudes.The agency now knows more about the moon and what to expect on the lunar surface. For example, ahead of the Apollo 11 moon landing, engineers worried that the moon dust wouldn't be stable enough to support the lunar lander or even astronauts walking on it.They discovered a different risk in the dust -- tiny shards of glass-like material. And the moon's temperature extremes could compromise the safety of the astronauts.The new suit is designed to keep out dust so that it doesn't infiltrate the life support system and can keep an astronaut safe between the temperature extremes of negative 250 degrees to 250 degrees Fahrenheit, accounting for shade and sun, especially at the south pole.The suit itself looks similar to the Apollo-era ones with its backpack functioning as the life support system that astronauts can wear on the lunar surface. It powers the suit, holds oxygen, removes toxic gases, odor and moisture from the suit, regulates temperature, monitors performance and issues warnings.But the most notable differences are in the details. Technology has been miniaturized to allow for duplicates to avoid errors. This could even allow for longer spacewalks."The Artemis Generation of spacesuits will fit everyone," said NASA Administrator Jim Bridenstine. "We want every person who dreams of going into space to have that opportunity."Anatomy of a spacesuitThe new suit is also slightly sleeker, allowing a greater range of motion while still protecting the astronauts from radiation, temperature extremes, and micrometeoroids.The main suit is a pressure garment consisting of a helmet, upper torso, lower torso and a cooling garment.A new communications system in the helmet replaces the "snoopy caps" the Apollo astronauts wore, which would fill with sweat. Instead of the microphones that would sometimes shift away from the astronauts mouth, multiple microphones are embedded that activate when the astronaut is talking.To allow for mobility, the upper torso has a new shoulder placement so the astronauts can move their arms in a range of motion, lift objects overhead or reach across their body. The Apollo suits only really accommodated up and down motion, but the new suit provides full arm rotation from shoulder to wrist.The lower torso, a new addition, will allow for better bending and rotating at the hips and knees. The so-called "moon boots" are similar to a hiking boot with flexible soles.One thing remains the same: the astronauts will continue to wear absorbing garments similar to diapers in the event that they need to go to the bathroom during a long spacewalk.Customization on the jobThe suits are comprised of parts that can lock together for a spacewalk on the lunar surface or even in zero gravity like outside of a spacecraft or the International Space Station. NASA wants to use this same technology when their astronauts attempt a Martian landing.The helmet will include a protective visor that can be replaced if it's damaged, scratched or dented. That way, astronauts can continue on with spacewalks rather than having to send the helmet back to Earth for repairs.Going from zero gravity to the limited gravity of the moon requires different capabilities. The lower torso, consisting of pants and boots, could be modified from supporting an astronaut walking on a surface compared to floating in space, where they don't need to use their legs as much.The suit will allow astronauts to climb into it from the back. This means the shoulder pieces can be closer together, allowing for a better fit, more mobility and reducing any risk of shoulder injury.Customization also means a better fit for astronauts. Each astronaut has a full body scan while wearing the suit at NASA's Johnson Space Center. That can be used to determine the best suit components for a particular astronaut to protect their full range of motion and ensure a perfect fit.The suits will undergo testing on the International Space Station before they're used for Artemis missions. NASA will then have a better idea of how the suits function in zero gravity while the astronauts conduct science and basic operations. 4385

While the 12 percent bump in pay may sound like a good deal, the cost of living in San Diego is also significantly more than similar-sized cities. The cost of living in San Diego is 22 percent more than Houston, 10 percent more than Phoenix and 12 percent more than Dallas, according to Expatistan. 299

Where are the recent burn areas? Most concerning: Thomas, Whittier, La Tuna, Sherpa, Fish, and Sand burns. If you are near these burns, DEBRIS FLOWS ARE LIKELY, stay alert to the weather and heed messages/evacuations from emergency officials. #larain #cawx #thomasfire #Montecito pic.twitter.com/UiEIltKpGi— NWS Los Angeles (@NWSLosAngeles) March 20, 2018 355

You know that feeling you sometimes have that someone’s watching you? Well, imagine you’re watching a horror movie on the couch, the lights are off, the hairs on the back of your neck stand up…and when you turn around, there they are, on the walls, all around you. These particular eyes are temporary, so you can put them up for the season—say, October?—and then take them down when you can’t handle the creep factor any longer. 428

Wildfire seasons -- already longer and more destructive than before -- could burn up to six times more forest area annually by 2050 in parts of the United States. Burned areas in Southwestern California alone could double by 2050.Dependable and safe water for the Hawaii, the Caribbean and others are threatened by these rising temperatures.Along the US coasts, public infrastructure and trillion in national wealth held in real estate are threatened by rising sea levels, flooding and storm surges.Energy systems will be taxed, meaning more blackouts and power failures, and the potential loss in some sectors could reach hundreds of billions of dollars per year by the end of the century, the report said.The number of days over 100 degrees Fahrenheit will multiply; Chicago, where these days are rare, could start to resemble Phoenix or Las Vegas, with up to two months worth of these scorching-hot days.Sea levels have already gone up 7 to 8 inches since 1900. Almost half that rise has been since 1993, a rate of rise greater than during any century in the past 2,800 years. Some countries are already seeing land underwater. By midcentury, it's likely that the Arctic will lose all sea ice in late summer, and that could lead to more permafrost thaw, according to the report. As the permafrost thaws, more carbon dioxide and methane would be released, amplifying human-induced warming, "possibly significantly." 1420
