  • 2021/01/15 DARPA Project Drives Simulation Technology for Off-Road Unmanned Vehicles
    DARPA's Robotic Autonomy in Complex Environments with Resiliency - Simulation (RACER-Sim) project is seeking innovations in technologies that bridge the gap from simulation to the real world and significantly reduce the cost of off-road autonomy development. DARPA invites proposals for promising solutions that support these goals.
  • 2021/01/15 DARPA Opens Door to Producing “Unimaginable” Designs for DoD
    DARPA's TRAnsformative DESign (TRADES) program, which began in 2017, set out to develop foundational design tools needed to explore the vast space opened by new materials and additive manufacturing processes commonly called 3D printing. The program recently concluded having successfully developed new mathematics and computational techniques, including artificial intelligence and machine learning, that will allow future designers to create previously unimaginable shapes and structures of interest to defense and commercial manufacturing.
  • 2021/01/13 Episode 38: The Oceanic Defender

    In this episode of the Voices from DARPA podcast, John Waterston, a program manager since 2017 in the agency's Strategic Technology Office, lets listeners in on his oceanic immersions both as a naval officer and a technology developer. Now a commander in the U.S. Naval Reserves, John offers snapshots of living, working, and serving on our nation's nuclear submarines before describing his current work at DARPA to develop technologies to better understand, monitor, and navigate the planet's most prevalent environment-the oceans. In one of his ambitious programs, John seeks to deliver what has been a coveted but elusive capability-the equivalent of GPS that operates even in the deep ocean. In a related program, John explains how very low-frequency (VLF) electromagnetic signals from lightning that occurs relentlessly around the world can become a key to a back-up positioning, navigation, and timing (PNT) system in case our must-have GPS goes down.

  • The K7RA Solar Update
    22 January 2021

    Tad Cook, K7RA, Seattle, reports: We just witnessed 12 consecutive days with no sunspots, which many of us found a bit unsettling. Fortunately, Solar Cycle 25 activity returned with new sunspot 2796 on January 15. Instead of moving from the east across the solar horizon, it emerged in the southern hemisphere, just west of center.

    Currently we are seeing sunspot regions 2797 and 2798, which emerg...

  • Eastern Iowans Rely On Ham Radio When Severe Weather Strikes
    21 January 2021

    A derecho with winds of 80 to 100 MPH struck eastern Iowa last August, disrupting power and telecommunications for some 400,000 residents. But, asARRL member and Amateur Radio Emergency Service (ARES®) volunteer Scott Haney, N0GUD, recently explained to The Gazette in Cedar Rapids, that’s when amateur radio shines.

    Haney, the president of the Cedar Valley Amateur Radio Club (CVARC), was the foc...
