    Space Age, scientists have understood how beyond Earth’s magnetic field, space is permeated by radiation. This includes Galactic Cosmic Rays (GCRs), Solar Particle Events (SPEs) ... NASA is able to protect crews from SPEs by advising them to seek shelter in more heavily shielded areas of the station... GCRs are more of a challenge. These energetic particles, which are primarily composed of high-energy protons and atomic nuclei, can come from anywhere within our galaxy and are capable of penetrating even metal. To make matters worse, when these particles cut through material, they generate a cascade reaction of particles, sending neutrons,...

    A thruster that's being developed for a future NASA mission to Mars broke several records during recent tests, suggesting that the technology is on track to take humans to the Red Planet within the next 20 years, project team members said. The X3 thruster, which was designed by researchers at the University of Michigan in cooperation with NASA and the U.S. Air Force, is a Hall thruster — a system that propels spacecraft by accelerating a stream of electrically charged atoms, known as ions. In the recent demonstration conducted at NASA's Glenn Research Center in Ohio, the X3 broke records...

    One of the techniques currently under development that it is following is NMN, a compound expected to enter clinical trials after it was shown to rejuvenate elderly mice in laboratory tests. It is also considering making more advanced tweaks or alterations to the DNA of its astronauts, although the moral implications of such a radical step will need to be addressed. This includes epigenetic modifications, which alter the way genes are read by the body without making changes to the underlying DNA code. Using such a technique would allow Nasa's scientists to turn up the volume on one genetic instruction...

    Mars Base Camp is very simple. Basically, it consists of an orbital outpost where scientist-astronauts will be transported to after leaving Earth and flying from the Deep Space Gateway into orbit around Mars. From this base, crews will be able to conduct real-time scientific exploration of the Martian atmosphere, followed by missions to the surface. ...[T]he major components of their base camp will be launched separately. Some will be pre-positioned in orbit around Mars ahead of time while others will be assembled in cis-lunar space for the journey to Mars. In the end, six astronauts will launch on an Orion...

    Lockheed Unveils Plans for Orbiting Mars Base Camp and Lander Within 10 Years By Mike Killian Mars Base Camp is Lockheed Martin’s vision for sending humans to Mars in about a decade. The Mars surface lander called the Mars Accent Descent Vehicle (MADV) is a single-stage system that uses Orion systems as the command deck. It could allow astronauts to explore the surface for two weeks at a time before returning back to the Mars Base Camp in orbit around Mars.

  • Study of Martian Sedimentary Layers Reveals More About the Planet’s Past

    universe today ^ | 19 Sep , 2017 | Matt Williams
    For years, Aeolis Dorsa has been of interest to scientists since it contains some of the most densely-packed sedimentary layers on Mars, which were deposited by flowing water (aka. fluvial deposits). These deposits are visible from orbit because of the way they have undergone a process known as “topographic inversion” – which consists of deposits filling low river channels, then being exhumed to create incised valleys. By definition, incised valleys are topographic lows produced by “riverine” erosion – i.e. relating to a river or riverbank. On Earth, these valleys are commonly created by rising sea levels, and then filled with...

    The human immune system is so weakened by space travel that even a simple virus could prove deadly [...snip...] Yet although we now have the technological ability to leave Earth, scientists have found another stumbling block to colonising new worlds - our own immune system. Although it is said we are all made of ‘star stuff’ when it comes to travelling away from our home planet humans are far more vulnerable to the rigours of space than our interstellar origins might suggest. Billions of years of evolution has effectively backed mankind into a corner of the Solar System that it...

    The InSight project, NASA’s first mission to study the Red Planet’s deep interior, is on track for a 2018 liftoff after needing to be delayed two years due to a technical issue. Scientists hope that it will help explain the formation of rocky planets, including our own. ... InSight is expected to launch sometime in the five weeks following May 8, 2018, with a course charted for its arrival shortly after Thanksgiving. Lockheed Martin Space Systems has constructed the mission’s spacecraft — a stationary lander that will be positioned near the Martian equator — and is currently testing it at...

    A mysterious ‘stone circle’ has been spotted on the surface of Mars, according to alien hunters. The image, captured by NASA’s Mars Curiosity Rover, was featured on the secureteam10 YouTube channel after it was spotted by a UFO hunter. In the YouTube video, secureteam10 describes the image as “a very strange formation of rocks that are put together in what appears to be a very artificial way, arranged in a perfect circle.” The formation is “much different from the craters that we normally see on Mars and the moon and the other planets in the solar system,” secureteam10 added. “This...

    President Donald Trump continues to sign legislation, an achievement he deemed “nice” Friday. The bills include an act to improve weather forecasting, a long-term vision for the National Aeronautics and Space Administration (NASA) and reforms for the Department of Veteran Affairs. The three pieces of legislation all had bipartisan support. The National Aeronautics and Space Administration Transition Authorization Act of 2017 calls for a $19.5 billion budget for NASA — an increase from $19.3 billion in 2016 — and also asks that NASA create a plan for getting humans “near or on the surface of Mars in the 2030s.” During...

    A mysterious circular rock formation on the surface of Mars has been captured by one of NASA's Orbiters. The formation was photographed by the Curiosity Rover this week and has excited alien hunters who invited speculation over how it came to be online. They suggested that the rocks were 'arranged', laid out by another form of life, or that it was part of a larger, buried structure which has never before been seen.

    Since it first began orbiting Mars in 2006, the HiRISE (High-Resolution Imaging Science Experiment), a powerful camera attached to the Mars Reconnaissance Orbiter, has captured some 50,000 images of the planet. Its photographs have given scientists unprecedented access to Mars’s canyons, craters, mountains and sand dunes – the most detailed looks at the topography of another planet to date. In making A Fictive Flight Above Real Mars, the Finnish filmmaker Jan Fröjdman transformed stereoscopic anaglyphs taken by HiRISE into coloured, seemingly three-dimensional moving images, giving viewers something resembling the experience of a leisurely flight above our neighbouring planet. While often...

    In an upcoming BBC program, Stephen Hawking has a new message for humanity: Get off Earth within the next 100 years or perish. In order to survive as a species, humans must colonize other planets. But Canadian astronaut Chris Hadfield has previously said that humans just aren't ready to live on other worlds. In 2015, he visited Business Insider to discuss his thoughts on where humans will go next and why. Hadfield became a mainstream figure thanks to his YouTube videos from space and wide social media presence. Now retired, Hadfield is the best-selling author of "An Astronaut's Guide to...

    Known as the Martian Moons Exploration (MMX) mission, the plan is to have a robotic spacecraft fly to Phobos and Deimos to explore their surfaces and return samples to Earth for analysis. The spacecraft would be deployed sometime in the 2020s, and would be tasked with two main objectives. The first would be to help scientists determine the origins of Phobos and Deimos, which has been a subject of debate for some time. Whereas some believe that these moons are capture asteroids, others have argued that they were created when fragments ejected from Mars (due to giant impacts on the...
