Pentagon To Test First Outer Space Laser Beam

  • The U.S. Naval Research Laboratory launched the Space Wireless Energy Laser Link—or SWELL—late Tuesday to demonstrate laser power beaming in space as part of a scheduled Defense Department Space Test Program H9 mission to the International Space Station, according to an agency announcement.
  • The SWELL experiment was launched aboard the SpaceX Dragon cargo vehicle to the ISS to “collect data during a laser power beaming link in space conditions.” According to the announcement, power beaming is a way to deliver energy in the form of electromagnetic waves that do not require transporting mass alongside them, so energy can be sent almost instantaneously. This method has been proven achievable on the ground and is now being tested in space. Specifically, it will explore the challenges for power beaming and its viability in space applications, as well as highlight the possibilities for using power beaming to address Earth’s energy challenges.
  • SWELL is one of many experiments on the SpaceX Dragon vehicle. The experiment is sponsored by the Office of the Under Secretary of Defense for Acquisition and Sustainment and supported by the Operational Energy Capability Improvement Fund.
