I saw this recently on Space – On This Day in Space! March 26, 1958: US Army Launches Explorer 3 Satellite: https://www.space.com/39251-on-this-day-in-space.html// Slightly longer article, but here’s what I considered the first portion of the article. I thought it was a good Space Saturday post.

On March 26, 1958, the United States launched its third satellite into space. Explorer 3 was almost identical to Explorer 1, the first satellite the U.S. ever launched.
Explorer 3 launched on a Juno I rocket from Cape Canaveral and entered an eccentric orbit. This means it was following a long elliptical path around the Earth. Its payload included a cosmic ray counter and a micrometeorite detector.
