Dr. Saganti earned his BSc degrees in Physics and Mathematics (1982) from Andhra Christian College, his MSc degree in Nuclear Physics from Andhra University in India (1986), another MS degree in Electro Optics (1991) from University of Houston, and a PhD degree in Theoretical Nuclear Physics (1994) from Andhra University in India.  His other educational training includes – University of Southern California (2007), Oxford (2008), Stanford (2011), ICTP (2012), Harvard (2014-2015), and Columbia (2016). His other National Labs research experiences as a guest scientist include – Brookhaven National Lab (from 2001) and Los Alamos National Lab (from 2004). Dr. Saganti is a tenured Professor of Physics at Prairie View A&M University, a member of Texas A&M System, with an additional responsibility as a Coordinator of the Physics Program appointed as a NASA-CARR Faculty.  He received several recognitions as a faculty member including Chancellor’s Teaching Excellence Awards (2009 and 2010).  In 2016, Dr Saganti was awarded the prestigious Regents Professor award by Chancellor Sharp.

Currently, Dr Saganti is leading the efforts of the first Chancellor Research Initiative (CRI), outside of the TAMUS campus as a Research Director of the Radiation Institute for Science and Engineering (RaISE) at Prairie View A&M University.  In partnership with Kyushu Institute of Technology (KIT-Japan) and NASA-JSC, Dr Saganti led his team to build and launch their first radiation detector payload onboard the Shinen2 spacecraft to deep-space launched by JAXA in 2014.  Dr Saganti is currently leading a new radiation payload for a polar orbit for Ten-Koh spacecraft of KIT-Japan to be launched by JAXA in August 2018. https://urldefense.proofpoint.com/v2/url?u=http-3A__www.pvamu.edu_raise&d=DwIF-g&c=oqyuZuih6ykib6aKiBq22_bich4AVfYGoLertJN0bEc&r=hjwEO_XYlnwAQWUGeaCrW47w4mK-Al28-BKyRvaivBs&m=Yge6dN1QqCIorusqUzKvIurN0LMtCD0aTHRV1LT_4YU&s=mRJ6zrS0a0Em-Vb_b8fud6QD_gYgNQwJvr9m5GYknBo&e=

Abstract

The Shinen2 spacecraft, currently in an elliptical orbit around the Sun between Venus and Mars orbits, was launched on December 3, 2014 as part of Hayabusa2 mission (an asteroid exploration mission on a second sample return challenge). The Shinen2 spacecraft, designed and built by the Kyushu Institute of Technology (KIT-Japan), is a hexagonal shaped, 15-kg, 47 x 49 x 49-cm structure built with light-weight and durable Carbon Fiber Reinforced Polymer (CFRP) with dual batteries charged by solar panels on each side of the structure and redundant UHF transmission systems at 437 MHz.  Shinen2 proved its success by transmitting data from Moon orbit and beyond at launch and after one orbit around the Sun. Shinen2's only payload is a radiation detector designed and built by Prairie View A&M University in collaboration with NASA Johnson Space Center (NASA-JSC), University of Texas (UT-Austin), and University of Nevada Las Vegas (UNLV).  The radiation particle pixel detector (PPD), a 10 x 10 x 10-cm cube structure was designed and developed as: (i) low weight (~ 800 gr), (ii) low power (~ 1 W), (iii) high reliability over few years (~ 5+ years), (iv) high tolerance in deep-space harsh radiation environment for a broad range of temperatures (-50o C to +50o C), and (v) with a unique capability to provide data downlink over a low bit rate communication transmission to Earth (few kilobytes) from deep-space. First results through the radiation belts and first orbit data will be presented and discussed with future anticipated plans.
