NASA has long been able to check out Mars on the ground with rovers and landers and from far above with orbital spacecraft. Now, it wants to prove that it can sustainably fly around the planet's thin atmosphere at low altitude -- with a tiny helicopter.NASA announced Friday it will send the Mars Helicopter to the Red Planet with the previously announced Mars 2020 rover, set to launch in two years from Florida.The hope is that aircraft like this one -- flying mechanical scouts -- will eventually give scientists another vantage point from which to observe Mars.The helicopter will be mankind's first attempt to fly a heavier-than-air craft -- think helicopter or airplane -- in an atmosphere other than Earth's, the space agency said.Its mission will be to take five test flights after it lands with the rover in February 2021. 839

At first, he was diagnosed with carpal tunnel syndrome. On Thanksgiving eve in 2004, Biagi fell down his stairs."My ankle gave way," Biagi explained. "That's when we knew something else was going on."Biagi lost use of his arms, hands and legs. It took four years for doctors to figure out what was going on. He was later diagnosed with chronic inflammatory demyelinating polyneuropathy. The disease is extremely rare."It affects approximately one to two people in 1,000 per year," said Dr. Robert Schabbing with Kaiser Permanente. "Alex has had a severe case of CIDP." When Biagi was first diagnosed, he gave up on art because his hands simply wouldn't allow it. But three years ago, he saw someone on the internet painting with their mouth."I never even thought about doing it that way," he said. "I finally decided to give it a try."For three years, Biagi has been practicing the unique craft and his paintings continue to get better and better.His latest piece of art is making the rounds on the internet. A picture of him touching up his painted portrait of superstar athlete LeBron James exploded on Reddit. 1346

NASHVILLE, Tenn. (AP) — Grammy-winning country group Lady Antebellum is changing its name to Lady A, with members saying they are regretful for not taking into consideration the word's associations with slavery. The band made up of Hillary Scott, Charles Kelley, and Dave Haywood, made the announcement Thursday on their social media. "After much personal reflection, band discussion, prayer and many honest conversations with some of our closest black friends and colleagues, we have decided to drop the word 'Antebellum' from our name and move forward as Lady A, the nickname our fans gave us almost from the start."The statement says that they chose the name after the antebellum-style home where they shot their first band photos, and it reminded them of Southern styles of music. Band members say in recent weeks, their eyes have been opened to "blindspots we didn't even know existed" and "the injustices, inequality, and biases black women and men have always faced." 982
