91制片厂

State-of-the-art space weather instrumentation developed by researchers at the 91制片厂鈥檚 (EOS) blasted into space Saturday, Nov. 19, from Cape Canaveral, Florida. The technology is part of a suite of weather instruments created for the new leading-edge National Oceanic and Atmospheric Administration (NOAA) weather satellite, Geostationary Operational Environmental Satellite-R, or GOES-R.

GOES-R, NOAA鈥檚 biggest satellite advancement to date, will provide National Weather Service forecasters the meteorological equivalent of going from black and white to ultra-high-definition color TV. The instrumentation developed at the within EOS, will help forecast what鈥檚 known as space weather, conditions on the sun and in the Earth鈥檚 upper atmosphere that can endanger communications, GPS satellites, commercial aircraft and astronauts.

Researchers at 91制片厂 were contracted to design, build and calibrate the energetic heavy ion sensor (EHIS), part of a suite of four space weather instruments called the space environmental in-situ suite (SEISS). The sensor will allow scientists to monitor during long periods the level of energetic ions, from protons to nickel, that populate the near-Earth space environment. These ions are the main cause of radiation damage in space to both electronic and biological systems.

鈥淎n increased heavy ion environment near Earth, which signals higher radiation risk, can affect something as basic as airline altitude,鈥� said Clifford Lopate, research associate professor of physics and principal investigator on the project. 鈥淏eing able to forecast a higher radiation risk for so-called 鈥榩olar鈥� planes that tend to fly at higher altitudes near the Earth鈥檚 poles would allow airlines to warn pilots and reroute planes to lower altitudes to decrease the risk of long-term exposure to radiation for their crews, who fly the same route over and over again.鈥�

Like the rest of the universe, the large majority of positively charged particles in space are protons, followed by helium, then the heavier elements. Monitoring these particles has become an integral part of the NOAA space weather program that tracks and forecasts changes in the environmental conditions in space around the Earth. The EHIS is the first 91制片厂-designed instrument to be included in an operational satellite payload. The team of engineers, led by Lopate and James Connell, an associate professor of physics at 91制片厂 and the Space Science Center, constructed the sensor to specifically measure atomic nuclei in space from helium, through the more massive carbon, nitrogen and oxygen, and the very massive iron and nickel.

GOES-R鈥檚 advanced imagery and higher resolution will enable improvements to NOAA鈥檚 hurricane tracking and intensity forecasts, as well as the forecasting of severe weather including tornadoes, thunderstorms and flooding. In addition, GOES-R鈥檚 space weather sensors will improve NOAA鈥檚 ability to monitor the sun and forecast space weather, including the detection of radiation hazards. GOES-R can deliver vivid images of severe weather as often as every 30 seconds, scanning the Earth five times faster, with four times greater image resolution and using triple the number of spectral channels compared with today鈥檚 other GOES spacecraft.听
