HAWTHORNE (CNS) - Southern California-based SpaceX will look to achieve another milestone late Friday evening when it attempts to launch the first test flight of its sleek capsule designed to carry astronauts to the International Space Station.The Crew Dragon, a stepped-up version of SpaceX's Dragon spacecraft that is used to carry cargo to the Space Station, is scheduled for to launch at 11:49 p.m. California time Friday from Cape Canaveral in Florida, propelled by a Falcon 9 rocket. The Crew Dragon mission will be unmanned, testing the new ship's capabilities and ability to self-dock at the Space Station.PHOTO GALLERY: SPACEX ROCKET LAUNCH LIGHTS UP EVENING SKYCargo-carrying Dragon capsules are usually captured by the Space Station's robotic arms and brought into the docking bay. The Crew Dragon is designed to dock and un-dock on its own.The Crew Dragon being launched Friday night will be carrying a sensor- laden mannequin, outfitted in a SpaceX spacesuit, along with about 400 pounds of supplies and equipment. The spaceship is expected to arrive at the International Space Station at about 3 a.m. California time on Sunday.The ship will remain docked at the station until about 11:30 p.m. Pacific time March 7, when it begins its journey back to Earth. It is expected to splash down in the Atlantic Ocean -- slowed by four parachutes -- about six hours later.VIDEO REPORT: No, it was not a UFO. SpaceX launches rocket into space off California coastAssuming the test flight goes well, SpaceX is scheduled to actually launch astronauts into space for a short demonstration flight this summer, possibly in July. NASA has already chosen astronauts Robert Behnken and Doug Hurley for the historic mission. Assuming no issues with that flight, two other astronauts -- Victor Glover and Mike Hopkins -- will later become the first humans carried by a Crew Dragon spacecraft to the International Space Station. 1929

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

GameStop announced this week that an additional 400 to 450 locations would close across the country by the end of 2020.While more video games are available for digital downloads, the next generation PS5 and Xbox will contain disc drives. The company was concerned that the next generation models would be digital only.Already in the last year, GameStop has closed 388 locations, shrinking its current retail footprint to 5,192 locations.“This will allow us to more efficiently and profitably service our customers,” company CEO George Sherman said about the closures.While many retailers have been shrinking their footprints as customers change their buying habits, GameStop is also encountering a change in technology in recent years, which has allowed customers to purchase games online.But GameStop says that there are some customers who prefer a physical disc, and that large video game downloads can use up internet data.“We believe the actions we are taking to optimize the core operations of our business by increasing efficiencies and creating a frictionless digital ecosystem to serve our customers, wherever and whenever they choose to shop, are enabling us to navigate the COVID-19 environment while positioning us well for the launch of the next generation of consoles,” Sherman said.GameStop saw a 26.7% drop in Quarter 2 sales in 2020 compared to 2019. 1374

Grilled cheese, tacos, hot dogs and more will likely be served by food trucks at the Royal Wedding this Saturday.Millennials Meghan Markle and Prince Harry have planned a huge celebration for their nuptials in England, and American comfort foods are rumored to be on the menu. There will likely also be late-night snacks available after the day-long celebratory events. 387

Hot weather can increase the risk of natural disasters like droughts and wildfires, now, there is evidence extreme heat can increase harmful chemicals in the air.A study published recently in Science Advances looked at asphalt under different temperature conditions.“A main finding is that asphalt-related products emit substantial and diverse mixtures of organic compounds into the air, with a strong dependence on temperature and other environmental conditions,” says Peeyush Khare, a Yale chemical and environmental engineer and the lead author of the study, in a statement.The researchers took real-world samples of fresh road asphalt and put them in a controlled furnace with purified air. They heated the samples to temperatures between 104 and 392 degrees Fahrenheit, and measured the chemical components in the air.Total emissions nearly doubled when temperatures went from 104 to 140 degrees. At 104 degrees, 94 percent of the emissions measured were hydrocarbons.The group also exposed the asphalt samples to replicated solar heat, including UVA and UVB wavelengths, and found the rate of emission of potentially harmful chemicals increased. Showing that not only heat, but also solar radiation contributed to asphalt producing air pollution.Paved surfaces and roofs make up approximately 45% and 20% of surfaces in U.S. cities, respectively.Asphalt can be quite a bit hotter than the air around it, getting about 40 to 60 degrees warmer than the recorded air temperature.The researchers concluded that while policies and regulations have been put in place about car emissions and other forms of air pollution, asphalt should not be overlooked as a contributor.“It's another important non-combustion source of emissions that contributes to SOA (secondary organic aerosol) production, among a class of sources that scientists in the field are actively working to constrain better,” Drew Gentner, associate professor of chemical & environmental engineering, said. 1983
