喀什怎样才能让男性更持久(喀什男性如何提高自己的性能力) (今日更新中)

Most new moms can relate; after being stuck inside with a newborn for several weeks, getting outside for fresh air and a different view is important.Mei Xiang at the Smithsonian National Zoo in Washington, D.C. took her newborn panda cub outside the den recently and into the main enclosure.It was a short field trip for the pandas, with Mei Xiang gently nudging her cub along the floor and keeping them out of the smaller den space.These field trips will get longer and more frequent as the cub gains more strength.At eight-weeks-old, the cub is practicing crawling and is not expected to take steps until closer to three-months-old.Zookeepers say the cub is packing on the pounds and has grown a coat of thick, wooly fur, able to help it regulate its body temperature. This means the cub can sleep on the floor of the den next to its mom. 848

NATIONAL CITY, Calif. (KGTV) — A nursing student's trip to a Starbucks in National City turned into an knock-down struggle and dramatic chase in pursuit of her laptop.With three finals next week, nursing student Jacqueline Ang spent the Friday using a computer at a library Bonita. "Grateful for the resource, but it's not the same," said Ang, who is wrapping up her first year in the nursing program at Southwestern College.It's not the same, because it doesn't have what she really needs: a year of notes. "It's devastating," said Ang.On Monday afternoon, she was studying with her MacBook Pro at a busy Starbucks on E. Plaza Boulevard. "Both earphones are in listening to lectures. One hand on my laptop, and the other hand taking notes," said Ang.Ang says she was at a table near the middle of the Starbucks when an older black teen in a hoodie walked in, and right up to her. He unplugged her earphones and turned to her computer. "Grabs it by the screen, closes it and starts running," said Ang.As the man ran off, Ang screamed to get someone's attention. She then took off after him. "When he's at the door, I'm able to grab him by the hoodie and bring him down. I'm saying, 'Please don't take it. Please don't take it,'" said Ang.On the ground, a struggle unfolded. Ang weighs just over 100 pounds."It's all that's on my mind. 'Omigod, everything I worked hard for is on that thing. I need that. I need to fight for that,'" said Ang.At some point during the struggle, she says the man was able to hand it off to another young man in a hoodie. Ang chased the other man, who slipped into a van in the parking lot. She was close behind, opening a side door. "I see three or four people in the van. I was holding onto the handle, running with the car as they're moving," said Ang.A bystander's short video shows her being dragged, before she let go. The incident left her with a sprained wrist and no laptop, but one big clue. Because Ang made the thieves' plans go awry, a witness was able to get the license plate number.National City Police asked 10News not to release the license plate in order to not endanger the investigation. A spokesperson says they see a handful of similar crimes every year, but haven't linked the suspects to any other incidents.A Gofundme campaign has been set up to help Ang purchase a new computer. 2344

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

NASA's OSIRIS-REx mission and the asteroid Bennu have had a date planned for two years, and just after noon ET today, they finally got to meet face to face. OSIRIS-REx fired its thrusters for a small burn, putting it about 4.3 miles from Bennu, marking the end of its journey to the asteroid.The mission -- which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer -- is NASA's first asteroid sample return mission. It launched in September 2016 and will spend two years up close and personal with Bennu. First images of the asteroid from the spacecraft's perspective have appeared as it got closer and closer.On Tuesday, the spacecraft will fly within 5 miles of Bennu, which will help design future orbits and map the surface.Over the next year, OSIRIS-REx will survey the asteroid using five scientific instruments on board the spacecraft. These instruments will help it determine a safe location from which to collect a small sample from Bennu's surface that will be returned to Earth in September 2023."Bennu's low gravity provides a unique challenge for the mission," said Rich Burns, OSIRIS-REx project manager at NASA's Goddard Space Flight Center. "At roughly 0.3 mile in diameter, Bennu will be the smallest object that any spacecraft has ever orbited."The sample from Bennu, a near-Earth asteroid, could help scientists understand not only more about asteroids that could impact Earth but about how planets formed and life began.OSIRIS-REx has a camera suite, a laser altimeter for 3D mapping, a thermal emission spectrometer to take temperature and mineral content and spectrometers to measure X-rays, nearly infrared and visible light.An arm mechanism called TAGSAM will reach out to collect the sample from Bennu's surface, making contact with the asteroid for five seconds in July 2020. During this contact, the arm will use a nitrogen gas burst to stir up rock and other materials on the surface so it can capture them. There is enough nitrogen for three attempts if the first is unsuccessful.NASA said the estimated 2.1-ounce sample size equates to about 30 sugar packets worth of dirt and rocks.The arm has a full range of motion, with joints capable of movement comparable to shoulder, elbow and wrist joints. It was "flexed" in space for the first time on November 14."The TAGSAM exercise is an important milestone, as the prime objective of the OSIRIS-REx mission is to return a sample of Bennu to Earth," said Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, Tucson. "This successful test shows that, when the time comes, TAGSAM is ready to reach out and tag the asteroid."In 2021, it will be time for the spacecraft to essentially turn around and begin its two-year journey home. The sample will be packed into a capsule that will drop in the Utah desert in 2023.For two years after the return, the sample will be cataloged and analyzed. Afterward, 75% of the returned sample will remain at NASA's Johnson Space Flight Center so it can be used for more research by scientists from around the world.Why did NASA select Bennu out of the 780,000 known asteroids in our solar system?It was discovered in 1999, and scientists have been studying it ever since. The asteroid fits a number of criteria that make it intriguing and convenient.Bennu is relatively close to Earth, and its orbit even crosses that of our planet, making a close approach every six years. Though small asteroids can rotate very quickly, Bennu has a diameter just a bit bigger than the height of the Empire State Building and rotates relatively slowly, each 4.3 hours. This means OSIRIS-REx can match its velocity and touch down briefly.The asteroid could pass close to Earth, closer than the moon, in 2135, with even closer approaches possible in 2175 and 2195. A direct hit is unlikely, but the data gathered during this mission can help determine the best ways to deflect near-Earth asteroids.The asteroid is also old and well-preserved, full of valuable materials that may even contain clues about how life began. Bennu is essentially a leftover from the formation of our solar system billions of years ago, although some of the minerals inside it could be even older.This carbon-rich asteroid could be full of organic molecules, metals, platinum and even water -- the essential ingredients for life. It's because of objects like Bennu that these resources were delivered to Earth during its formation.Asteroids could even serve as fuel stations for robotic and human missions if we can unlock the hydrogen and oxygen inside them, NASA said.Bennu probably broke off of a larger asteroid in the asteroid belt between Mars and Jupiter a couple billion years ago. This knocked it through space until an orbit close to Earth locked it in place. And Bennu is believed to be a grouping of rocks held together by gravity rather than a single object.But its orbit drifts 0.18 miles each year toward the sun, and OSIRIS-REx will enable researchers to understand why and to predict Bennu's movements. This could also explain how it ended up as a near-Earth asteroid."The story of this asteroid is the story of the solar system," said Bashar Rizk, instrument scientist for OSIRIS-REx. "When we understand Bennu, we will understand something fundamental about our solar system."The-CNN-Wire 5356
