  • NASA Spacecraft Reactivated to Hunt for Asteroids

    A NASA spacecraft that discovered and characterized tens of thousands of asteroids throughout the solar system before being placed in hibernation will return to service for three more years starting in September, assisting the agency in its effort to identify the population of potentially hazardous near-Earth objects, as well as those suitable for asteroid exploration missions.

    The Wide-field Infrared Survey Explorer (WISE) will be revived next month with the goal of discovering and characterizing near-Earth objects (NEOs), space rocks that can be found orbiting within 28 million miles (45 million kilometers) from Earth’s path around the sun. NASA anticipates WISE will use its 16-inch (40-centimeter) telescope and infrared cameras to discover about 150 previously unknown NEOs and characterize the size, albedo and thermal properties of about 2,000 others — including some which could be candidates for the agency’s recently announced asteroid initiative.

  • Private Asteroid-Mining Project Launching Tiny Satellites in 2014

    A billionaire-backed asteroid-mining company aims to start putting its big plans into action soon, launching its first hardware into space by this time next year.

    Planetary Resources, which counts Google execs Larry Page and Eric Schmidt among its investors, plans to loft a set of tiny “cubesats” to Earth orbit in early 2014, to test out gear for its first line of asteroid-prospecting spacecraft.

    “Our belief and our philosophy is that the best testbed is space itself,” Chris Voorhees, Planetary Resources’ vice president of spacecraft development, said Wednesday (April 24) during a Google+ Hangout event.

    “Despite the fact that we’re a deep-space company, we’re going to use Earth orbit as much as possible,” Voorhees added. “For us, it’s a valuable learning experience, and that’s what we plan on doing one year hence.”

    The cubesats slated for launch in 2014 will measure 12 inches long by 4 inches wide by 4 inches tall (30 by 10 by 10 centimeters), company officials said. These “Arkyd-3” satellites will test out technologiesfor Planetary Resources’ Arkyd-100 scouts, which the firm hopes to launch to low-Earth orbit on asteroid-hunting missions in 2015.
