• 2021/03/02 DARPA Announces Research Teams Selected to Semantic Forensics Program
  Media manipulation capabilities are advancing at a rapid pace while also becoming increasingly accessible to everyone from the at-home photo editor to nation state actors. As the technology evolves so does the national security threat posed by compelling media manipulations. While the issue today may be Deepfake videos, the ability to generate falsified multimodal assets - such as news stories with embedded photos and videos - from whole cloth may not be far off. To take on this growing threat, DARPA created the Semantic Forensics (SemaFor) program.
• 2021/03/01 Episode 40: Sounds of Innovation 2
  Welcome to Sounds of Innovation, an intermittent feature of our Voices from DARPA podcast. Rather than hearing the voices of program managers, which is normally what you get in a Voices from DARPA podcast, in each Sounds of Innovation episode, you will hear some of the soundscapes of research and development…and learn just a little bit about the world-changing capabilities those sounds could lead to. See if you can guess how the sounds were produced before our podcast host reveals their origin.
• 2021/02/23 Technologies to Rapidly Restore the Electrical Grid after Cyberattack Come Online
  Some 330 million Americans rely on the nation's critical infrastructure to keep the country humming. Disruptions to electrical grids, communications systems, and supply chains can be catastrophic, yet all of these are vulnerable to cyberattack. According to the government's 2019 World Wide Threats Hearing, certain adversaries are capable of launching cyberattacks that can disrupt the nation's critical infrastructure - including electrical distribution networks.

• ARISS, NASA, and ESA Continue to Probe Amateur Radio Problems on ISS
  03 March 2021

  Amateur Radio on the International Space Station (ARISS) International Chair Frank Bauer, KA3HDO, reports that the ARISS team has been working closely with NASA and the European Space Agency (ESA) to identify what may have caused what ARISS is calling a “radio anomaly” on January 27. The net result has been an inability to use the NA1SS ham station gear in the ISS Columbus module. For the time...

• AMSAT-DL Operators Track Mars Probes
  03 March 2021

  Members of Germany’s AMSAT organization, AMSAT-DL, in cooperation with the Sternwarte Bochum Institute in Bochum, Nordrhein-Westfalen, Germany, have been using the institute’s 20-meter (65.6-foot) diameter dish antenna to listen directly to signals from probes in Mars orbit.

  Signals have been copied from the Chinese Tianwen-1 and the Hope Emirates Mars Mission (EMM) spacecraft now orbiting Mars...
