The Upper Atmosphere Research Satellite (UARS) was a NASA-operated orbital observatory whose mission was to study the Earth's atmosphere, particularly the protective ozone layer. The 5,900-kilogram (13,000 lb) satellite was deployed from Space Shuttle Discovery during the STS-48 mission on 15 September 1991.
The UARS mission objectives were to provide an increased understanding of the energy input into the upper atmosphere, global photochemistry of the upper atmosphere, dynamics of the upper atmosphere, the coupling among these processes, and the coupling between the upper and lower atmosphere. This provided data for a coordinated study of the ...
UARS may refer to: Upper Atmosphere Research Satellite, an orbital observatory whose mission was to study the Earth's atmosphere, particularly the protective ozone layer, and which crashed on Earth in 2011; Upper airway resistance syndrome, a sleep disorder characterized by airway resistance to breathing during sleep
The Upper Atmosphere Research Satellite (UARS) was a science satellite used from 1991 to 2005 to study Earth's atmosphere, including the ozone layer. Planned for a three-year mission, it proved much more durable, allowing extended observation from its instrument suite.
The USART's synchronous capabilities were primarily intended to support synchronous protocols like IBM's synchronous transmit-receive (STR), binary synchronous communications (BSC), synchronous data link control (SDLC), and the ISO-standard high-level data link control (HDLC) synchronous link-layer protocols, which were used with synchronous voice-frequency modems.
Upper airway resistance syndrome (UARS) is a sleep disorder characterized by the narrowing of the airway that can cause disruptions to sleep. [ 1 ] [ 2 ] The symptoms include unrefreshing sleep, fatigue , sleepiness, chronic insomnia , and difficulty concentrating.
Flight tracking enables travellers as well as those picking up travellers after a flight to know whether a flight has landed or is on schedule, for example to determine whether it is time to go to the airport. Aircraft carry ADS-B transponders, which transmit information such as the aircraft ID, GPS position, and altitude as radio signals.
At the time, there were few enterprise solutions that offered this kind of service. Baker recruited friends Karl Lehenbauer and David McNett to help create a free public flight tracking service. On March 17, 2004, FlightAware was officially founded and began processing live flight data. [4]
