The Associated Press reports that two NASA Viking space probes visiting Mars in 1976-77 may have come across alien microbes and killed them by drowning and overheating them, according to a paper released at an American Astronomical Society meeting in Seattle. It was accidental, since the probes were looking for Earth-like life, not the hydrogen peroxide-based life that could have evolved on Mars in the Red Planet’s cold, dry conditions. A NASA official told AP the agency is revising its definition of “life.”
The Air Force is shoring up its cyber defenses both on and off base for critical infrastructure such as water and electrical power, and industry experts are calling for more, even specialized, dedicated microgrids offsite to support USAF operations in case of a total blackout caused by cyberattacks.
