He was there when man first landed on the moon in 1969 and on Friday, Buzz Aldrin endorsed a new galactic effort — the Trump administration's Space Force."One giant leap in the right direction. #SpaceForce," the retired astronaut tweeted, quoting a message from Vice President Mike Pence about the initiative.On Thursday, Pence called for the establishment of a Space Force by 2020 and noted the Department of Defense would be taking to steps to reform the military's approach to space. The announcement comes after President Donald Trump said in June that he was directing "the Pentagon to immediately begin the process necessary to establish a Space Force as the sixth branch of the armed forces." The establishment of the new military service would require congressional approval. 791

Google and Apple teamed up to create a software that allows a COVID-19 tracking app to work. It’s part of a recent software update on smartphones.Now, Virginia is the first state to make an app using the technology. It's called COVIDWISE. It's similar to contact tracing but isn't exactly the same.COVIDWISE uses Bluetooth technology to measure distance between different people and how much time they've spent together. Both people need to have the app installed.Users will receive an alert if someone around them tests positive for coronavirus and it won't reveal who it was.While not everybody needs to have the app, the more people who do, the better.“For every one to two app users, you're potentially averting one infection, so I think that's a good take-home message,” said Jeff Stover, Executive Program Advisor at the Virginia Department of Health. “So, obviously the more of them there are, the more potential infections that we avert.”The app is really only meant to notify people if they've been exposed to the coronavirus. It's not meant to eliminate traditional contact tracing.“Traditional contact tracing is still important. It is still required. It's really how we get in touch with people to determine if they have questions, if they have prevention activities that they need to figure out,” said Stover.Another thing about the app is that it does not use location data. Virginia's health department says there's really no need for it, especially because that type of data doesn't really show the distance between people.Right now, the app can only be used in Virginia, but the state of North Dakota has said the app will be available for use there soon. 1680

Grab your headphones and prepare to be blown away.NASA just announced it has heard the first-ever "sounds" of wind on Mars. But if you're expecting howling, swooshes and crackles, you're in for a surprise. These are vibrations, captured by NASA's InSight lander, which touched down on the Red Planet just last week. The craft will stay put until November 24, 2020, measuring quakes that happen anywhere on Mars.This week, the craft recorded something unexpected."InSight sensors captured a haunting low rumble caused by vibrations from the wind, estimated to be blowing between 10 to 25 mph (5 to 7 meters a second) on Dec. 1, from northwest to southeast," the agency said.An air pressure sensor and a seismometer recorded the noise through the vibrations in the air and vibrations around the aircraft "caused by the wind moving over the spacecraft's solar panels."This is the only time when vibrations from the lander will be recorded by the seismometer, since it will be moved by the craft's robotic armed and placed on the Martian surface, along with other instruments.The craft's landing comes as part of NASA's mission to explore the planet's deep interior.InSight lander's sensors are designed to detect quakes and air pressure through wind vibrations. The lander will measure whether tremors have the same effect as earthquakes. The Seismic Experiment for Interior Structure (SEIS), the seismometer, will use the vibrations to help scientists configure more about the planet's interior."Capturing this audio was an unplanned treat. But one of the things our mission is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves," Bruce Banerdt, the InSight principal investigator at NASA's Jet Propulsion Laboratory, said in a statement.To better hear this bass sound, it's better you bring out your headphones, or your subwoofer, as NASA suggested.You can hear the sounds here and listen to NASA's news telecon with a panel of scientists here.The-CNN-Wire 2011

Have you heard of the "Dirty Dozen" list? Every year, it lists the 12 fruits and veggies that have the most pesticides. Now, one group of researchers says the list may be scaring people unnecessarily.Laura Molina works to make sure her customers at her community market, Growhaus, pick the best fruits and veggies.“We try to bring everything organic and local,” Molina said.It ends up being a mix. So, when customers ask her how to pick between organic and conventional, she often gives them advice she takes herself.“Everything that I can peel, I can buy, like, not organic,” Molina explains. “But like lettuce, mushrooms, apples, I try to buy them organic.”But is there a set rule for choosing? Every year, a nonprofit called the Environmental Working Group puts out the "Dirty Dozen," a list of the 12 fruits and veggies most contaminated by pesticide residue.This year, apples, celery and tomatoes made the list.However, a group of scientists say these foods may not be as dirty as some once thought, and the way the EWG analyzed the data is flawed.“The benefit of fruits and vegetables far outweighs the potential concern of this pesticide residue,” registered dietitian Jessica Crandall said.Crandall says consumers would have to eat a lot of a certain fruit or vegetable to be affected by any pesticides.“You would have to be eating so many cups,” Crandall said. “Like 400-plus cups of strawberries per day in order for that residue to be a potential concern if you're an adult. And if your kid, needs to be around 200 cups per day of strawberries.”Those concerned about pesticides in produce can visit safefruitsandveggies.com to check pesticide levels in any produce item.Ultimately, the decision shouldn't be based on a list.“I believe it is a personal choice,” Crandall said. “And so if you like the way that it tastes, better then to go ahead and consume. But if you're worried about the safety of it I don't think that's a concern you need to be aware of.”Crandall and Molina both agree — no matter what you decide next time you check out, a good fruit or veggie is always a healthy choice.  2162

HELENA, Mont. – Republican Steve Daines of Montana won a second Senate term on Tuesday, dealing a blow to Democrats' hopes of gaining a majority in the chamber.The former business executive and Donald Trump loyalist defeated Gov. Steve Bullock.Daines’ first election in 2014 broke a Democratic lock on the Senate seat that had lasted more than 100 years. After Trump carried Montana by more than 20 percentage points in 2016, Daines emerged as one of the president’s ardent defenders.Bullock is a two-term Montana governor who entered the race in March after dropping a presidential bid that attracted little support.Political groups and the campaigns poured more than 0 million into the contest, a record-shattering figure for the sparsely populated state. 768
