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
Zarnow and another deputy soon spotted Ibarra, who matched the description of the assailant, near a stretch of train tracks beneath an elevated section of Via de la Valle in Del Mar, a few blocks south of the restaurant, Lt. Greg Rylaarsdam said. When the lawmen called out to him, Ibarra allegedly walked out from behind a concrete bridge support with a knife in his hand and strode toward the deputy closest to him, who lost his footing and fell down while backing away. 472
Zambada, 57, who has been in police custody since 2008 and is being held in U.S. custody, is the first of several cooperators who are testifying against Guzman in hopes of leniency at sentencing. The defense says the deals have given them an incentive to exaggerate the role of Guzman, who pleaded not guilty after being extradited to the U.S. last year. 354
Women's March co-president Tamika Mallory responded with an open letter claiming the ad was a "direct endorsement of violence" against protesters. 146
You are stuffed and tired, and now you have to travel home.? NORTHEAST: It is never good when you start off the day with delays. That might just happen Sunday morning. Northeast metro areas could see rain early and throughout the day. Most of the wintry precipitation should stay sequestered farther north into Maine.? SOUTH: It looks like the misery of Saturday's rain will have subsided, but the residual hangover may still have some effect on travel. Low clouds could be an issue in the early morning.? MIDSECTION: A low exits the Rockies and brings snowy conditions from light snow in the front range, across Kansas. Most of south and central Missouri stay on the warmer side, with rain mostly in places such as St. Louis. Kansas City on the other hand, will see rain changing to snow Sunday morning with blowing snow by mid-day as winds pick up. This swath of snow will impact southern Iowa and extend all the way to Chicago by Sunday evening.? WEST: It finally dries out, so you might be able to get a sunny ski session in before battling the roadways. The drive up and down the West Coast will be tremendously better than it was Wednesday.All in all, the weather this week is much better than in previous years so most of you won't be able to use it as an excuse. Don't think you're going to be able to get out of turkey and turmoil with your in-laws. 1358
