The interaction between the solar wind and the medium of our galaxy creates a complex host of interactions, which is thought to shield the majority of harmful galactic radiation that reaches Earth and fills the solar system.
The magnetic fields of our galaxy may change the protective layers of our solar system that regulate the entry of galactic radiation, which affects Earth and poses hazards to astronauts," said Nathan Schwadron of Boston University's Center for Space Physics and the lead for the IBEX Science Operations Center at BU.
Solar and galactic radiation of meter to millimeter wavelengths was discovered last.
Even before the official formation of Program C, the Naval Research Lab pioneered space reconnaissance with the development of the Galactic Radiation and Background (GRAB) satellite launched in 1961 to collect electronic intelligence.
The purpose of GRAB, the Galactic Radiation and Background Experiment, was to measure solar radiation.
It was in 1965 that two Bell Labs physicists, Arno Penzias and Robert Wilson, set up an experiment to measure the radio emission coming from the Milky Way galaxy and were in the process of calibrating their antenna at a wavelength of 7 cm, where galactic radiation was at a minimum.
U-2 spy aircraft was shot down over the Soviet Union, Lorenzen's most notable achievement became the Galactic Radiation and Background payload, GRAB, the earliest space-based reconnaissance satellite and the first U.
In 1965, a couple of physicists at Bell Labs, Arno Penzias and Robert Wilson, were in the process of measuring the radio mission coming from our galaxy, the Milky Way, and had calibrated their antenna at a wave-length of 7 cm, where galactic radiation is at a negligible minimum.
This testing will focus on medical device sterilization radiation requirements, galactic radiation test protocol for space-based applications and weapons radiation protocols.
