    Tests show that dormant herpes viruses reactivate in more than half the astronauts who travel on the Space Shuttle and International Space station, according to new NASA research - a phenomenon the space agency says could pose problems for deep space missions. ..."In keeping with this, we find that astronaut's immune cells - particularly those that normally suppress and eliminate viruses - become less effective during spaceflight and sometimes for up to 60 days after."
  • Dormant viruses activate during spaceflight

    "NASA astronauts endure weeks or even months exposed to microgravity and cosmic radiation—not to mention the extreme G forces of take-off and re-entry," says senior author Dr. Satish K. Mehta of KBR Wyle at the Johnson Space Center. "This physical challenge is compounded by more familiar stressors like social separation, confinement and an altered sleep-wake cycle." "During spaceflight there is a rise in secretion of stress hormones like cortisol and adrenaline, which are known to suppress the immune system. In keeping with this, we find that astronaut's immune cells—particularly those that normally suppress and eliminate viruses—become less effective during spaceflight...

    U.S. Rep. Ralph Abraham is urging President Donald Trump to consider Louisiana for the future headquarters of Trump’s proposed Space Force. The Republican congressman wrote a letter to the president , suggesting Louisiana was an "ideal location" because of its strong existing relationships with the military and NASA. Abraham, who is running for governor, says Space Force would "fit perfectly" at Barksdale Air Force Base in Bossier City. He notes NASA's existing Michoud Assembly Facility in New Orleans has built components for the nation's space program for decades...
  • Tesla launches '1,000 miles per hour' charging station for Model 3

    03/09/2019 10:28:58 AM PST · by ETL · 72 replies ^ | Gary Gastelu | Fox News
    The so-called V3 Supercharger operates at 250 kilowatts -- approximately twice that of the older stations -- and can charge some of its cars at a rate of 75 miles every five minutes, which Tesla is promoting as “1,000 miles per hour,” without explaining the math. (75 x 12 = 900, doesn't it?)(Following the publication of this article, a Tesla representative clarified that the "1,000 mph" speed is a peak rate that is only sustained for a portion of the initial five-minute period on batteries at a low state of charge. Average speeds over longer charging times were not...

    According to NASA's press kit, "Crew Dragon will autonomously undock from the International Space Station on Friday, March 8, at approximately 2:30 a.m. EST [0730 GMT]. About five hours after Dragon departs the space station it will conduct its deorbit burn, which lasts up to 15 minutes. It takes about 35 to 40 minutes for Dragon to re-enter the Earth's atmosphere and splash down in the Atlantic Ocean, which is currently targeted for approximately 8:45 a.m. EST [1345 GMT]." There has been a lively discussion on the satellite observer Seesat Internet List about spotting the bright plasma trail created by...
  • Splashdown! SpaceX’s Crew Dragon capsule returns to Earth

    SpaceX’s unmanned Crew Dragon capsule has splashed down in the Atlantic Ocean after its historic DEMO-1 test flight to the International Space Station. The capsule, carrying a dummy dubbed ‘Ripley,’ made its return to Earth after undocking from the ISS early Friday. After plunging through the Earth’s atmosphere, Crew Dragon deployed its parachutes and splashed down at 8:45 a.m. EST. The six-day test flight is a crucial step in SpaceX’s plan to provide human spaceflight. Lessons learned from DEMO-1 should improve safety when two NASA astronauts strap into a Dragon as early as July.
  • Solar Wind Leaves 'Sunburn' Scars on the Moon

    People on Earth who've gotten sunburns are familiar with the sun's powerful rays — but the moon suffers from sunburn, too. Some regions of the lunar surface exhibit a distinctive pattern of darker and lighter swirls. Using NASA's ARTEMIS mission — which stands for Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon's Interaction with the Sun — astronomers have revealed new clues about the origin of these swirls. The sun releases a constant flow of charged particles known as solar wind into space. While Earth's natural magnetic field deflects solar-wind particles, the moon has a weaker magnetic field, leaving some areas of...
  • The first look at how hacked self-driving cars would affect New York City traffic

    As automated cars become more commonplace, it is increasingly likely that internet-connected vehicles could be simultaneously disabled. Currently, regulators tend to focus on preventing individual incidents, like the pedestrian who was struck and killed by a self-driving Uber in Arizona last year. However, they fall short of addressing the effects of a large-scale hack in an urban setting. This week at the 2019 American Physical Society March Meeting in Boston, Skanda Vivek will present his research on the cyber-physical risks of hacked internet-connected vehicles. He will also participate in a press conference describing the work. Information for logging on to...

    Lucid Motors, a Silicon Valley start-up that is gearing up to launch an advanced electric luxury car, said that it has struck a preliminary deal with Electrify America to provide its future customers with a nationwide recharging plan. This is an important deal. Tesla's (NASDAQ:TSLA) Supercharger network has given it a big advantage in winning buyers away from internal-combustion alternatives. Any company looking to challenge Tesla will be at a disadvantage unless it can also provide its buyers with assurance that they'll be able to access high-speed chargers on road trips. Lucid isn't yet public, but it just won a...

    Tucked away inside Israel’s Beresheet lunar lander, currently on its way to the Moon, is a massive archive documenting humanity’s achievements. The collection of images, text and symbols is the first part of a project to build a “Lunar Library” and part of a bigger push to create a space-based archive of Earth. According to the Arch Mission Foundation (AMF), the library contains 30 million pages of human history that covers a wide range of subjects, languages and time periods, all stored on a DVD-sized archive made of 25 nickel discs that are each only 40 microns thick. An 84-page document...

    On board Beresheet is a specially designed disc encoded with a 30-million-page archive of human civilization built to last billions of years into the future. The backup for humanity has been dubbed "The Lunar Library" by its creator, the Arch Mission Foundation (AMF). The disc aboard Beresheet is about the size and thickness of a DVD, but consists of 25 stacked thin nickel films that AMF insists can resist radiation, extreme temperatures and other harsh conditions found in space for billions of years. There is, of course, no way to test how long it will last, but if it survives...
  • SpaceX’s New Crew Capsule Aces Space Station Docking

    03/03/2019 8:04:04 AM PST · by BenLurkin · 40 replies
    While SpaceX has sent plenty of cargo Dragons to the space station, crew Dragon is a different beast. It docked autonomously under the station astronauts’ watchful eyes, instead of relying on the station’s robot arm for berthing. The capsule’s nose cap was wide open like a dragon’s mouth, to expose the docking mechanism. Behnken said that’s the way it should work when he and Hurley are on board; they may push a button or two and will have the ability to intervene, if necessary. As part of Sunday’s shakedown, the station astronauts sent commands for the Dragon to retreat and...

    After years of on-the-ground development and testing, the SpaceX spaceship that’s destined to carry NASA astronauts is going on its first uncrewed test mission to the International Space Station tonight — and you can watch the historic liftoff from multiple angles. When SpaceX’s Crew Dragon capsule lifts off from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida, atop a Falcon 9 rocket, there won’t be any humans aboard. But there will be a crew member of sorts. SpaceX has placed a spacesuit-wearing, sensor-laden mannequin in one of the Dragon’s seats, to gather data about how rigorous the...
  • NASA’s Curiosity Mars Rover Recovers After Serious Glitch

    When Curiosity attempted to come back online after an inactive period — a process it’s completed more than 30 times previously, according to the post — a glitch triggered a “protective safe mode.” Scientists back on Earth are working to forensically reconstruct what happened during the hiccup by downloading a snapshot of its memory. They’re also taking a hiatus from its scientific work — which is frustrating for researchers, pointed out, because they’d been about to drill an “intriguing rock” about 650 feet from the rover’s current location. “In the short term, we are limiting commands to the vehicle...
  • Why It'll Take Israel's Lunar Lander 8 Weeks to Get to the Moon

    The robotic lander, called Beresheet, launched atop a SpaceX Falcon 9 rocket yesterday evening (Feb. 21) from Florida's Cape Canaveral Air Force Station. If everything goes according to plan, Beresheet will zip around Earth for about six weeks in ever-widening orbits before heading toward its final destination. The craft will arrive in lunar orbit in early April and attempt a landing on the 11th of that month. Beresheet's lengthy stay in Earth orbit may seem surprising. After all, China's Chang'e 4 farside lander reached lunar orbit just 4.5 days after its Dec. 7 liftoff (though Chang'e 4 didn't actually touch...
