DESCRIPTION:The Growing Interest in Space Constellations and Their Potentia
 l Effects on the Durability and Reliability of the Space Environment\nTues
 day\, August 29\, 2023\, at 12:50 pm\nLocation: In-Person MAE-A\, Room 303
 \nNorman Fitz-Coy\, PhD\nAssociate Professor\, UF Department of Mechanical
  &amp\; Aerospace Engineering\nAbstract\nThe space environment surrounding
  the Earth is becoming more\ncongested with systems that vary in mass\, sh
 ape\, and material (e.g.\, spacecraft\, launch vehicles\, and subsystem/co
 mponents of either). Recent collisions and/or ASAT missions have (i) resul
 ted in increased debris fragments generated in orbit.\nBiography\nNorman F
 itz‐Coy is the Director of the Space Systems Group (SSG) at the\nThe Uni
 versity of Florida focuses on the development and validation of\ntransform
 ative technologies with specific applications to small satellites. Within 
 SSG\, his recent activities focus primarily on technologies for small sate
 llites and space situational awareness (SSA). With regard to small satelli
 tes\, he has developed the smallest control moment gyroscopes (CMGs) for t
 he attitude control of CubeSats and have also developed and flown a missio
 n to demonstrate these devices. SwampSat\, UF’s first CubeSat in 2012\, 
 was a 1U CubeSat (10 cm x 10 cm x 10 cm) that included as its payload thes
 e CMGs. Unfortunately\, none of the three CubeSats within the launch pod (
 SwampSat and two other 1U cubes) were successfully launched\, and prelimin
 ary analysis indicated a short circuit occurred within the launch pod. Dr.
  Fitz‐Coy followed this mission with SwampSat II in 2019\, which was a 3
 U CubeSat also developed by SSG and was designed to measure very low frequ
 ency (VLF) wave propagation in Earth’s upper atmosphere. The spacecraft 
 utilized a novel 16‐meter square‐loop antenna system designed to fit w
 ithin the small envelope of a 3U CubeSat. For his SSA efforts\, the past d
 ecade has seen the\ndesign of a generalized low Earth orbit (LEO) satellit
 e\, its fabrication and testing\, the performance of a hypervelocity impac
 t test at the Arnold Engineering Development Complex in Tennessee\, the co
 llection and transportation of the resulting debris fragments to UF for ch
 aracterization\, and now the development of a one‐of‐a‐kind debris d
 atabase for NASA and DoD to characterize potential debris fields resulting
  from on‐orbit‐collisions. His talk today discusses will emphasize thi
 s project\, referred to as DebriSat.\nMAE Faculty Host: Larry Ukeiley
