  • Should Space X Be Trusted to Lead Us Back to the Moon?

    04/27/2019 5:53:46 AM PDT · by Kaslin · 30 replies ^ | April 27, 2019 | Jerry Rogers
    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...

    There’s a new member of an exclusive space race club this week. India announced that they successfully shot down a small satellite in low Earth orbit. But if you think this is a reason for anyone other than India to celebrate, you’ll probably want to reconsider that idea. (The Independent) India has shot down a live satellite in space as part of a successful test of new missile technology, prime minister Narendra Modi has announced.The operation, dubbed Mission Shakti, makes India part of a “super league” of nations to have achieved such a feat, Mr Modi said, alongside the...

    India shot down one of its satellites in space with an anti-satellite missile on Wednesday, Prime Minister Narendra Modi said, hailing the country’s first test of such technology as a major breakthrough that establishes it as a space power. India would only be the fourth country to have used such an anti-satellite weapon after the United States, Russia and China, said Modi, who heads into general elections next month.

    That sad trombone you hear is the sound of NASA’s attempt at a history-making spacewalk falling apart. After conducting the first spacewalk this week, astronaut Anne McClain noted that the large suit she was wearing did not allow her to move effectively. “McClain learned during her first spacewalk that a medium-size hard upper torso – essentially the shirt of the spacesuit – fits her best,” according to a statement from NASA. Because only one medium-size torso would be ready by the planned Friday spacewalk, NASA astronaut Christina Koch will use the suit.

    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."

    "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...
  • 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...

    While the team found that the bacteria isolated from the ISS did contain different genes than their Earthling counterparts, those genes did not make the bacteria more detrimental to human health. The bacteria are instead simply responding, and perhaps evolving, to survive in a stressful environment. As the conversation about sending travelers to Mars gets more serious, there has been an increasing interest in understanding how microbes behave in enclosed environments. "People will be in little capsules where they cannot open windows, go outside or circulate the air for long periods of time," said Hartmann. "We're genuinely concerned about how...

    Research has shown that time in space can increase the risk of cancer and trigger gene mutations. But a new study has found that one crucial part of the human body remains unaffected by zero-gravity. in space didn’t alter an astronaut’s levels of B-cell immunity — the white blood cells that create antibodies to fight off infections. B-cell levels need to be maintained in order to help astronauts fight off disease-causing viruses and bacteria. For the study, scientists took blood samples from 23 crew members stationed at the International Space Station for six months, before, during and after their stays....

    TOKYO (AP) — A German-French observation device safely landed on an asteroid on Wednesday after a Japanese spacecraft released it as part of a research effort that could find clues about the origin of the solar system, Japanese space officials said. The Japan Space Exploration Agency said the Mobile Asteroid Surface Scout, or MASCOT, was released from the unmanned spacecraft Hayabusa2 and successfully landed on the asteroid Ryugu. The spacecraft went as close as about 50 meters (160 feet) to the asteroid’s surface to release the box-shaped lander.
  • How Fast Is Earth Moving?

    How Fast Is Earth Moving? As an Earthling, it's easy to believe that we're standing still. After all, we don't feel any movement in our surroundings. But when you look at the sky, you can see evidence that we are moving. Some of the earliest astronomers proposed that we live in a geocentric universe, which means that Earth is at the center of everything. They said the sun rotated around us, which caused sunrises and sunsets — same for the movements of the moon and the planets. But there were certain things that didn't work with this vision. Sometimes, a...

    Starting? When did it stop? The real question is: who’s paying for it now? Space has just come to the forefront because we now recognize how critical Space has become to our life. Civil space technology is now WAY ahead of our military. Strangely this is more a race between US Venture Capitalists and the Russians, Chinese, North Korea and Iran. The military is along for the ride. The Space Race has become one where our commercial companies are now developing and providing capabilities at a price that our military can only dream of and foreign country militaries just read...

    NASA's newest planet-hunting telescope is officially at work. The Transiting Exoplanet Survey Satellite (TESS), which is designed to hunt for alien worlds around stars not too far from the sun, began gathering science data Wednesday (July 25), members of the instrument team announced yesterday (July 27). TESS will send that initial data to Earth in August, with new observations arriving every 13.5 days after that, mission team members said in a statement. "I'm thrilled that our planet hunter is ready to start combing the backyard of our solar system for new worlds," Paul Hertz, director of NASA's Astrophysics division, said...
