Explorer 19 1963 53A Inflatable Balloon Atmospheric Research Spacecraft Family
Explorer 19 was a NASA inflatable spherical balloon satellite launched December 19, 1963 into a near-polar orbit. Its very low mass-area ratio enabled atmospheric-density measurements from orbital drag, while its beacon and tracking observations supported studies of ionospheric electron content and communications conditions.
