Seaver College Research And Scholarly Achievement Symposium
Changes in the interplanetary magnetic field (IMF) orientation can affect pulsations in the dayside aurora. It has been reported that multiple dayside arcs(Pc 5 band) were replaced by diffuse pulsating aurora (Pc 3-4 band) when the IMF turned northward. Dayside green (557.7 nm emission) pulsating aurora had been reported to occur between 0800 and 1100 MLT (0500-0800 UT) in patches. The pulsations are normally associated with Pc 3-5 range. This statistical study examines pulsating green aurora using ground-based optical data are obtained from the Kjell Henriksen Observatory (KHO) in Longyearbyen, Svalbard (GEO: N, E; AACGM: N, E).

Congressional Committee Resources On Space Policy During The 115th Congress (2017-2018): Providing Context And Insight Into Us Government Space Policy, Bert Chapman
Libraries Faculty and Staff Presentations
Article 1 of the US Constitution assigns the US Congress numerous responsibilities. These include creating new laws, revising existing laws, funding government programs, and conducting oversight of these programs' performance. Oversight of US Government agency space policy programs is executed by various congressional space policy committees including the House and Senate Science Committees, Armed Services, and Appropriations Committees. These committees conduct many public hearings on space policy, which invite expert witnesses to testify on US space policy programs and feature debate on the strengths and weaknesses of these programs. Documentation produced by these committees is widely available to the public, …

The Earth's Magnetosphere, Soren Ormseth
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The Interstellar Boundary Explorer (IBEX) is an Earth orbiting satellite launched in 2008; designed to map the boundary of our Solar System. In this presentation, we focus on how data collected by the IBEX-Hi sensor can be used to map the distribution of hot ions within the Earth's magnetosphere. As opposed to other satellites, IBEX images the magnetosphere from afar rather than by going through it. An improvement on the previous imaging techniques was developed, and we compare the new results to the old.

Shape Modeling And Boulder Mapping Of Asteroid 1992 Uy4, Nicholas Duong
Posters-at-the-Capitol
The structure and history of near-Earth asteroids are important to
study because they collide with Earth, sometimes with significant consequences for
climate and the survival of many species, including our own. If NASA is ever to deflect an asteroid on a collision course, it is crucial to know as much as possible about its size, composition, structure and boulder distribution. The boulder
distribution in turn helps to map the asteroid's gravitational field.
1992 UY4 is a near-Earth asteroid discovered in 1992. In August 2005, UY4 made a
``close" (for space) pass of Earth, about 15x farther than the Moon. It …
