nasa研究太陽與地球輻射帶之影響

Mission managers at NASA's Kennedy Space Center in Florida have given the go for the launch of the Radiation Belt Storm Probes spacecraft, targeted for 4:08 a.m. EDT on Thursday, Aug. 23.
RBSP will study the Earth's radiation belts to help us better understand the Sun's influence on Earth.
At NASA's Kennedy Space Center in Florida, the Flight Readiness Review for the agency's Radiation Belt Storm Probes spacecraft and the United Launch Alliance Atlas V rocket is complete. There were no significant issues identified that would be a constraint to launch on Aug. 23. A launch countdown dress rehearsal will be conducted on Friday. The Launch Readiness Review is to be held Aug. 20 and will give the launch team the nod to proceed toward liftoff, with rollout of RBSP atop the Atlas V on Aug. 21.

The Radiation Belt Storm Probe mission (RBSP) will explore the Van Allen Radiation Belts in the Earth's magnetosphere. The charge particles in these regions can be hazardous to both spacecraft and astronauts. Project Scientist David Sibeck explains the how the mission will explore space weather -- changes in Earth's space environment caused by the sun -- that can disable satellites, create power grid failures and disrupt GPS service. The mission also will allow researchers to understand fundamental radiation and particle acceleration processes throughout the universe.

The 2-year mission is scheduled to launch no earlier than 4:08 a.m. Thursday, Aug. 23 from Cape Canaveral Air Force Station in Florida. The twin probes will lift off on a United Launch Alliance Atlas V rocket.

動態摘要：
美國航天局宣布將於8月23日發射兩個探測器，研究地球上空的輻射帶範艾倫帶。探測器將進入橢圓形軌道，研究範艾倫帶內的粒子如何產生、它們在太空氣候事件中的活動以及促使這些粒子加速的機制。該“輻射帶風暴探測器”任務將持續兩年。範艾倫帶是科學家詹姆斯·範艾倫於1958年發現的由高能粒子組成的輻射帶，其內帶位於地球上空650公裏至6300公裏處，外帶位於地球上空1萬至6.5萬公裏處。範艾倫帶內的高能粒子對載人空間飛行器、衛星等都有一定危害，其內外帶之間的縫隙則是輻射較少的安全地帶。
