The mission, supported by a grant from the <strong>National Science Foundatio<\/strong>n (NSF), aims to investigate regions of natural ionospheric turbulence. According to the release, these patches of disturbed ions and electrons corrupt radio transmissions and wreak havoc on essential Earth and space-based communication and navigation channels.<\/p>\n<p>The ISX investigation is meant to examine thousands of Digital Terrestrial Television (DTT) channels known to penetrate the patch regions for evidence of signal corruption. Because the ground-based DTT transmitters have fixed locations and stable operating frequencies, they form a global network of signals ideally suited for imaging the internal structure of the disturbed ionospheric patches. As the ISX orbits, it will receive signals from multiple DTT transmitters to form a 3D image of emergent disturbances, an observational technique similar to a medical CAT scan.<\/p>\n<p>The DTT scan technique relies on a multi-channel digital radio receiver developed at SRI International specifically for the ISX space weather mission. The design and operation of this receiver is based on two prior <strong>National Science Foundation<\/strong> (NSF) space weather missions, the Radio Auroral Explorers (RAX-1 and RAX-2), which discovered similar ionospheric turbulence patches driven by the aurora in Earth\u2019s polar regions. &nbsp;SRI researchers have also designed, assembled, and successfully flown radio and ultraviolet sensors on space-weather research missions for <strong>NASA<\/strong>, NSF, and the <strong>U.S. Air Force<\/strong>.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An&nbsp;SRI International cubesat space-weather mission, the Ionospheric Scintillation Explorer (ISX), was launched into space on Dec. 15 as one of the payloads on the most recent Rocket Lab launch.
