  • A High Energy Revelation

    A High Energy Revelation

    Measurements of unprecedented detail returned by Japan’s Hitomi satellite have allowed scientists to track the motion of X-ray-emitting gas at the heart of the Perseus cluster of galaxies for the first time. Located about 240 million light-years away and named for its host constellation, the Perseus galaxy cluster contains a vast amount of extremely hot gas. At temperatures averaging 90 million degrees Fahrenheit (50 million degrees Celsius), the gas glows brightly in X-rays. Prior to Hitomi’s launch, astronomers lacked the […]

    Asteroid Redirect Mission Robotic Trajectory and Crew Operations

    This concept animation opens with a rendering of the mission’s spacecraft trajectory, rendezvous, and approach to asteroid 2008 EV5. Although the mission’s target asteroid won’t officially be selected until a year before the robotic spacecraft is launched, 2008 EV5 is used as a reference for mission planning details. The animation concludes with the notional crew operations that will take place after the asteroid boulder is placed in lunar orbit. Enjoy and share……..

    On the Edge of Forever – International Cooperation

    Star Trek first hit the airwaves in 1966 – a period of time when geopolitical tensions were at their highest. Not that you would know that by looking at the diverse crew of the Enterprise. The creators of Star Trek knew that if humans are to someday explore the universe, we would need to put aside our differences and boldly go forth as citizens of Earth. NASA and its international partners adopted a similar model when conceiving humanity’s first International […]

  • To Bennu And Back

    To Bennu And Back

    NASA’s latest New Frontiers mission, OSIRIS-REx, will venture to a near-Earth asteroid to discover clues about the unique resources asteroids hold, processes that affect asteroids’ orbital paths and their potential for impacting Earth, and the origins of life in the solar system. In addition, OSIRIS-REx will collect a sample from the surface of the asteroid and return it to Earth for generations of scientists to study and analyze, making this the first American asteroid sample return mission and the largest […]

  • Breakups

    Breakups

    Breakups: You think yours were bad? You might think your breakup with your high school sweetheart after 2 years of canoodling was bad but it’s got nothing on what happens to asteroids. These space rocks smash into each other, hurtling towards the inner Solar System and after writing a love letter identifying all those responsible; they stream towards Earth meeting the atmosphere. Here’s where it gets messy, there are recorded accounts of these jilted monsters putting on spectacular light shows […]

Credit: NASA/JPL-Caltech; D. Lang/Dunlap Institute While taking a second look at data collected by the Wide-field Infrared Survey Explorer (WISE) space telescope, two scientists confirmed the presence of an X-shaped star structure in the Milky Way’s central bulge. The existence of the structure has been a subject of debate […]

    Morse Code Message On The Surface Of Mars?

    NASA Has Found A “Morse Code Message” On The Surface Of Mars NASA’s eyes in the Martian sky came across some odd-looking dashes and dots on the surface of the Red Planet recently, which they pointed out has an eerie similarity to Morse code. The image was taken on February 6, 2016, by the High Resolution Imaging Science Experiment (HiRISE) onboard the Mars Reconnaissance Orbiter (MRO), which has been exploring Mars since 2005.

  • Surveying an Asteroid with X-rays

    Surveying an Asteroid with X-rays

    NASAs OSIRIS-REx mission launches in September 2016 and plans to return a sample of asteroid Bennu to Earth in 2023. This video profiles a student-built instrument aboard the OSIRIS-REx spacecraft called REXIS – the Regolith X-Ray Imaging Spectrometer. The purpose of REXIS is to collect and image fluorescent X-rays emitted by the asteroid, which will give scientists information regarding atomic elements that comprise it. Enjoy and share…….
