Lockheed Martin SR-72 Lockheed Martin SR-72 The Lockheed Martin SR-72 is an American hypersonic UAV concept intended for intelligence, surveillance and reconnaissance. Lockheed Martin privately proposed it to succeed the retired Lockheed SR-71 Blackbird. The SR-71 Blackbird retired in 1998, leaving what was considered a coverage gap between surveillance satellites, manned aircraft, and unmanned aerial vehicles for intelligence, surveillance and reconnaissance (ISR) and strike missions. With the growth of anti-satellite weapons, anti-access/area denial tactics, and counter-stealth technologies, a high-speed aircraft could penetrate protected airspace and observe or strike a target before enemies could detect or intercept it. The proposed reliance on extremely high

An understanding of space weather and – in particular – its impacts on society are in their infancy, but there is broad agreement that societal sensitivity to high-impact, low-frequency events is obviously substantial. Equally important is the need to thoroughly investigate how space weather impacts various components of our high-tech society, and identify the mechanisms by which it does so.
