The primary goal of the Stardust mission was to collect samples of a comet and return them to Earth for laboratory analysis. Comets are ancient bodies of frozen ice and dust that formed beyond the orbit of the most distant planet. They were expected to contain materials that the solar system formed from, preserved in ice for billions of years. When the international team of 200 scientists began examination of the returned particles, we found that the particles were indeed ancient building blocks of the solar system but the nature and origin of the particles was quite unexpected.

The Joint Tactical Ground Station (JTAGS) is the Army’s element to USSTRATCOM’s Theater Event System (TES). TES The ongoing cooperation between the Army and Air Force continues to be essential to the long-term growth of the Army’s space professional cadre. High Frontier provides an integrated, in-theater, 24-hour overhead non-imaging infrared detection capability for processing and disseminating missile early warning, alerting, and cueing information data to combatant commanders and missile defense assets through the use of stereo processing of the Defense Support Program (DSP) satellite data. The TES is composed of three ground elements: the Space-Based Infrared System (SBIRS) Mission Control…
The following documents are not categorized in their proper sub-category. Until then, they will remain indexed here: Survey of Communication and Navigation Concept for Space Escape System, 16 Jun 1969 [61 Pages, 2.92MB] – During manned space operations in near earth orbit, an emergency can occur where mission abort or onboard procedure is incapable of resolving the hazard. A space eacape system is, therefore, being investigated as a possible solution. Since the escape system is an emergency device, its design is not constrained by purely military consideration. Thus, while military missions require secure communication links and recovery sites, space escape systems are not…
