It's the end of another era at NASA, although this one was perhaps more inevitable than others. Chief Information Officer Linda Cureton announced in a blog post over the weekend that the agency's last mainframe computer was shut down this month, marking an end to decades of room-filling computers. Of course, that last mainframe was considerably more recent than that pictured above. It was an IBM Z9 (pictured at the source link below), still quite a behemoth and useful for certain applications, but deemed unnecessary by NASA in the face of other more flexible alternatives. Feeling nostalgic or curious about those days gone by? You can find a bit of mainframe history at the links below.
