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 conducted its first test of a Minuteman III intercontinental ballistic missile in 2026 on March 3, launching an unarmed missile from Vandenberg Space Force Base, Calif., equipped with two test reentry vehicles at 11:01 p.m. Pacific Time.
