New Tactical ISR Satellites Provide Global, Persistent Support For Warfighters
Lockheed Martin is addressing the accelerating demand for space-enabled warfighting capabilities with a new line of rapid, integrated and affordable tactical Intelligence, Surveillance and Reconnaissance (ISR) satellites.
These satellites, based on Lockheed Martin's LM 400 mid-size bus, enable tactical warfighters to track moving targets at long ranges and operate in contested and denied e Fast-spinning black holes narrow the search for dark matter particles
Ultralight bosons are hypothetical particles whose mass is predicted to be less than a billionth the mass of an electron. They interact relatively little with their surroundings and have thus far eluded searches to confirm their existence. If they exist, ultralight bosons such as axions would likely be a form of dark matter, the mysterious, invisible stuff that makes up 85 percent of the matter
