Interplanetary space is permeated by energetic particles from galactic cosmic rays and from the Sun. This Rapid Response Research (RAPID) project will make unique measurements of energetic particles in interplanetary space by integrating the Relativistic Electron and Proton Telescope integrated little experiment-2 (REPTile-2) into the Emirates Mission to the Asteroid Belt (EMA). This is a unique opportunity to refurbish instrumentation originally developed as part of the NSF CubeSat program for a new active mission with an international collaboration with the United Arab Emirates. A graduate and two undergraduate students will gain hands-on experience in building, testing, and calibrating the space flight instrument.The United Arab Emirates (UAE) is currently developing the Emirates Mission to the Asteroid Belt (EMA). University of Colorado Boulder’s Laboratory for Atmospheric and Space Physics (LASP) is the “knowledge transfer partner” on EMA, involved with spacecraft bus building and integration of the science instruments. EMA will have a narrow launch window in March 2028 to carry out the mission. The spacecraft will perform a series of flyby/gravity assists at Venus, Earth, and Mars, before the first asteroid flyby in early 2030. The mission will conclude by rendezvousing with a seventh main belt asteroid, Justitia, in October 2034. This project will support refurbishment of the REPTile-2 instrument, originally developed as part of the successful NSF Colorado Student Space Weather Experiment (CSSWE) CubeSat mission, for integration with the EMA spacecraft. The new REPTile-3 instrument will provide detailed measurements of energetic particles from 3-100 MeV protons and 0.2-5 MeV electrons in 129 channels. The following science questions will be addressed: (1) How do the energy spectra of solar energetic particles (SEPs) evolve with time and location in the heliosphere? (2) What is the relative contribution of SEPs vs galactic cosmic ray (GCR) and anomalous cosmic ray (ACR) protons with energies up to 100 MeV near the Earth’s space environment, including Moon’s surface? (3) What is the energy spectrum dependence of space weather effects on spacecraft either in the interplanetary medium or orbiting around the Earth but exposed to direct entrance of SEPs, GCRs, and ACRs?This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

行星际空间充满了来自银河宇宙射线和太阳的高能粒子。该快速响应研究（RAPID）项目将通过集成相对论电子和质子望远镜集成小实验 2（REPTile-）对行星际空间中的高能粒子进行独特的测量。 2) 进入阿联酋小行星带任务 (EMA) 这是一个翻新仪器的独特机会，这些仪器最初是作为 NSF CubeSat 计划的一部分开发的。与阿拉伯联合酋长国进行国际合作的新的活跃任务。一名研究生和两名本科生将获得建造、测试和校准太空飞行仪器的实践经验。阿拉伯联合酋长国（阿联酋）目前正在开发酋长国任务。科罗拉多大学博尔德分校大气与空间物理实验室 (LASP) 是 EMA 的“知识转移合作伙伴”，参与航天器总线的建造和科学仪器的集成，将有一个狭窄的发射窗口。三月2028 年执行任务。在 2030 年初首次飞越小行星之前，该航天器将在金星、地球和火星上进行一系列飞越/重力协助。任务结束时将与第七颗主带小行星 Justitia 会合。 2034 年 10 月。该项目将支持 REPTile-2 仪器的翻新，该仪器最初是作为成功的 NSF 科罗拉多州学生空间天气实验的一部分而开发的(CSSWE) CubeSat 任务，用于与 EMA 航天器集成，新的 REPTile-3 仪器将在 129 个通道中提供 3-100 MeV 质子和 0.2-5 MeV 电子的高能粒子的详细测量，将解决以下科学问题： (1) 太阳高能粒子 (SEP) 的能谱如何随时间和日光层中的位置而演变？ (2) SEP 与银河系的相对贡献是什么？地球空间环境（包括月球表面）附近能量高达 100 MeV 的宇宙射线 (GCR) 和反常宇宙射线 (ACR) 质子（3）空间天气对行星际介质或航天器的影响的能谱依赖性如何？绕地球轨道运行但暴露于 SEP、GCR 和 ACR 的直接入口？该奖项反映了 NSF 的法定使命，经评估认为值得支持利用基金会的智力优势和更广泛的影响审查标准。
