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 Space Force should take bold, decisive steps—and soon—to develop the capabilities and architecture needed to support more flexible, dynamic operations in orbit and counter Chinese aggression and technological progress, according to a new report from AFA’s Mitchell Institute for Aerospace Studies.
