<p>The ability to predict the occurrence and magnitude of solar particle events (coronal mass ejections and solar flares) has been elusive so exposure of astronauts and flight electronics to this radiation is a serious concern for NASA.&nbsp;&nbsp;This&nbsp;work&nbsp;focuses on exposure of operational flight electronics to solar particle events, which can jeopardize human safety.&nbsp; The NOAA Space Weather Scale uses the terminology &ldquo;Solar Radiation Storms&rdquo; to describe solar particle events and categorizes the level of event severity on a scale from S1 (Minor) to S5 (Extreme).&nbsp; The size of these events spans orders of magnitude and therefore the resulting exposure to energetic particle radiation can cause a wide range of effects depending on the severity of the event.&nbsp; For an S1 level event the effect on satellite operations according to the NOAA scale would be &ldquo;none&rdquo; while for an S5 level event &ldquo;satellites may be rendered useless, memory impacts can cause loss of control, may cause serious noise in image data, star-trackers may be unable to locate sources; permanent damage to solar panels possible&rdquo;.</p><p>The end result of this IRAD will be a <strong>quantitative</strong> &ldquo;nowcasting&rdquo; tool for solar storms with classification of the severity of the storm according to the NOAA Space Weather Scale for ease of interpretation by mission operations.&nbsp; &nbsp;This would be used by mission operations as input for making decisions on whether systems and instrumentation should be shut down during an event.&nbsp; These decisions would be driven by the particular features and susceptibilities of each spacecraft and its payload.</p><p>FY13 will be dedicated to development and verification of the quantitative aspects of the model techniques.&nbsp;&nbsp;Short term predictions of solar storms will be verified based on space data taken by the GOES Space Environment Monitor (SEM) and the CRaTER instrument on the LRO spacecraft.&nbsp; The latter is in an approximately 50 km circular lunar orbit.</p>

Summary
Description
A new secure web-based system that tracks the approval process of the DS-2019 applications and participant information. The Office of Education uses VCS to track the foreign national's entry to, and departure from, the US, their attendance at training/exchange visitor programs, and to obtain the State Department's DS-2019 form in order to apply for a visa for travel to the United States. VCS facilitates data interchange between TraiNet and Student and Exchange Visitor Information System (SEVIS). VCS performs three functions: First, it implements a process to verify data from TraiNet. Second, it translates TraiNet data to the format required by SEVIS and manages its transmission. Lastly, it provides approval management of requests for applications as they move through the workflow process. VCS holds data regarding foreign nationals who receive instruction funded by USAID, whose training will take place in the United States, and to request a J-1 visa for travel to the United States.
