  • Scientists Have Developed a Way to Make Human Skin More Protected from Space Radiation

    07/09/2020 7:07:14 PM PDT · by BenLurkin · 15 replies
    NASA says that astronauts can be exposed to doses of radiation ranging from 50 to 2,000 Milli-Sieverts (mSv). Researchers already know that melanin has potential to protect astronauts from radiation. But there are different types of melanins. The one being tested on the ISS is actually a composite of fungal melanin and polymers. The lead researcher on that work is Radamés J.B. Cordero from Johns Hopkins. But this new research is going in a slightly different direction, by looking at melanin enriched with selenium. Selenium has an interesting relationship with light, and is used as a pigment, in glassmaking, in...

    NASA's Perseverance Mars rover has been attached to the top of the rocket that will send it toward the Red Planet this summer. Encased in the nose cone that will protect it during launch, the rover and the rest of the Mars 2020 spacecraft – the aeroshell, cruise stage, and descent stage – were affixed to a United Launch Alliance Atlas V booster on Tuesday, July 7, at Cape Canaveral Air Force Station in Central Florida. The process began when a 60-ton hoist on the roof of the Vertical Integration Facility at Space Launch Complex 41 lifted the nose cone,...
  • NASA Mars Helicopter Will Be Red Planet’s ‘Wright Brothers Moment’

    06/23/2020 11:26:09 AM PDT · by Red Badger · 42 replies ^ | June 23, 2020 | Staff
    NASA is about to take to the air on another planet. As part of its next mission to Mars, leaving Earth this summer, the space agency will attempt to do something that has never been done before: fly a helicopter through the rarefied atmosphere of Mars. If it works, the small helicopter, named Ingenuity, will open a new way for future robotic explorers to get a bird’s-eye view of Mars and other worlds in the solar system. “This is very analogous to the Wright brothers moment, but on another planet,” said MiMi Aung, the project manager of the Mars helicopter...

    By harnessing the innovation unleashed by the free enterprise system, private space enterprise is ready to explore the next untapped horizon: asteroids. We’re going to the moon. We’re going to Mars. And, before you know it, we’ll be going to the asteroid belt.Space is back, baby. It’s back in the news, back in our thoughts, and back in the culture. America, and the world, are better for it.Over the past few years, space exploration has returned to public consciousness in ways not since the first shuttle mission in 1981, or even since Americans landed men on the moon then brought...

    VIDEO There was very much of a "2001: A Space Odyssey" vibe when the SpaceX Crew Dragon docked with the International Space Station (ISS). Therefore it just had to be done. Setting that docking event to the tune of the Blue Danube. Welcome to "2020: A Space Odyssey." No Stanley Kubricks were harmed in the making of this video.
  • SpaceX Launch Represents President Trump's Commitment to America-First Leadership

    NASA and SpaceX launched the first space exploration from American soil in nearly a decade, from the Kennedy Space Center, after the Space Shuttle and Constellation programs were retired under the Obama administration. The latter program was created in hopes of sending Americans to the moon by the year 2020, but President Obama canceled the effort during his first term in office.  Restoring American space exploration was a key campaign goal of President Trump’s, and Saturday’s launch is years in the making. President Trump re-established the National Space Council, created the Space Force as the official sixth branch of...

    Amid the pandemic, the SpaceX launch should inspire us to be risk-takers, trying new things and starting new ventures. We can only achieve great things if we don't let fear dictate how we live our lives. Two American astronauts, Doug Hurley and Bob Behnken, will strap themselves in the Dragon capsule, which sits on top of the Falcon 9 rocket — both built by Elon Musk’s company SpaceX — and depart for the International Space Station on May 27.This extraordinary event embodies much historic significance. The Falcon 9 rocket will be launched from the same launch pad at the Kennedy...

    NASA’s top executive concentrating on human spaceflight, Doug Loverro, has resigned just a week before the scheduled start of a milestone space mission. Loverro became NASA’s associate administrator for human exploration and operations last December, and was playing a leading role in NASA’s Artemis moon program as well as preparations for next week’s launch of a SpaceX Crew Dragon mission to the International Space Station. That mission, set for liftoff on May 27 from NASA’s Kennedy Space Center in Florida, is due to send NASA astronauts Doug Hurley and Bob Behnken to the station for a stay that could last...

    Perseverance's descent stage was also fueled up last weekend, just before the helicopter integration, NASA officials said. The descent stage is the rocket-powered sky crane that will lower Perseverance onto the Martian dirt via cables in February 2021. Gassing up the crane was no trivial task; the craft's four tanks hold a total of 884 lbs. (401 kilograms) of hydrazine propellant, agency officials said. "The last hundred days before any Mars launch is chock-full of significant milestones," David Gruel, the Mars 2020 assembly, test and launch operations manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, said in a...

    A team of astronomers from NASA’s New Horizons mission has unveiled our best look yet at the far side of Pluto, which went unseen to the spacecraft during its historic July 2015 flyby of the dwarf planet. We have only seen one hemisphere of Pluto in high-resolution because the New Horizons flyby of Pluto lasted just hours, whereas the dwarf planet takes 6.4 Earth days to rotate. Thus as New Horizons flew past, one side of the world was illuminated by the Sun, but the other was shrouded in darkness. However, using images taken by the spacecraft while it was...

    The race to conquer space is real – and the United States could lose to China if we don’t act now.We know that China continues to work to consolidate opposition to the U.S. through its alliances with Iran, Russia, and North Korea. Just last week, the president of China met with the president of Iran to continue to foster their relationship. This is a slap in the face to the U.S. given that Tehran was—a few days prior—directly implicated in the attack on two tankers. And with China’s aggressive actions at sea, it’s only a matter of time before there...

    On April 20, 2019, the space community was buzzing from its most recent frustrating setback: The Crew Dragon, SpaceX’s most advanced space launch capsule, suffered some catastrophic anomaly. A day later, leaked footage from the incident purportedly showed the vehicle erupting in a fireball as it self-destructed during testing. The critical failure of the Crew Dragon—a shuttle designed to transport astronauts into space—does little to build confidence in the ongoing partnership between SpaceX and NASA. As the Trump Administration begins its push to send Americans back to the moon, SpaceX’s recent misfortunes have left many questioning whether Musk’s company should be...
