DESCRIPTION:"JEM-EUSO\, POEMMA\, and PBR: Hunters of UHECRs and VHENs from 
 Orbital and Suborbital Altitudes" \n\n \n\nPresented by Dr. Johannes Eser\
 , Associate Research Scientist\, from Columbia University\n\n \n\nUltra-hi
 gh-energy cosmic rays remain one of the major open questions in astroparti
 cle physics. Answering these questions requires next-generation instrument
 s\, which can be divided into high-accuracy and high-exposure observatorie
 s\, the latter providing far greater exposure than current ground-based de
 tectors. The long-term goal of the JEM-EUSO and POEMMA programs is to maxi
 mize exposure at the highest energies by building a space-based multi-mess
 enger observatory capable of detecting ultra-high-energy cosmic rays and v
 ery-high-energy neutrinos with full-sky coverage.\n\nA major step toward t
 his goal is the POEMMA-Balloon with Radio mission\, PBR\, an ultra-long-du
 ration balloon payload planned for launch from Wanaka\, New Zealand\, in S
 pring 2028. As the latest and most advanced pathfinder designed and built 
 by the JEM-EUSO collaboration\, PBR will validate key elements of the inst
 rument design and observation strategy. While circling over the Southern O
 cean during an expected flight of more than 20 days\, PBR will pursue thre
 e main scientific objectives: (1) fluorescence detection of ultra-high-ene
 rgy cosmic rays (E>1EeV) from suborbital space\, (2) optical Cherenkov and
  radio observations of high-altitude horizontal air showers\, and (3) foll
 ow-up of astrophysical alerts in the search for very-high-energy neutrinos
  (E>1PeV). In this talk\, we will discuss the motivation why going to spac
 e is advantages\, present the design of POEMMA  followed by close look at 
 its latest pathfinder PBR.
