The small satellite 'Galileo Galilei' (GG) will test the universality of free fall and hence weak equivalence principle which is founding pillar general relativity to 1 part in 1017. It use proof masses whose atoms differ substantially from one another their mass energy content, so as maximize chance violation. GG improve by four orders magnitude current best 'Eöt-Wash' tests based on slowly rotating torsion balances, have been able reach thermal noise level. In GG, expected violation signal...
Abstract The China Seismo-Electromagnetic Satellite ( CSES ) aims to monitor electromagnetic, particle, and plasma perturbations in the iono-magnetosphere inner Van Allen radiation belts originated by electromagnetic sources external internal geomagnetic cavity, cosmic rays, solar events. In particular, objective of space mission is investigate lithosphere–atmosphere–ionosphere coupling mechanisms (including effects lightning, earthquakes, volcanoes, artificial emissions) that induce top...
Abstract High-energy, long gamma-ray bursts (GRBs) can be generated by the core collapse of massive stars at end their lives. When they happen in close-by universe exceptionally bright, as seen from Earth case recent, giant, long-lasting GRB221009A. GRB221009A was produced a collapsing star with redshift 0.152: this event observed many space experiments, which also detected an extraordinary afterglow. The large fluence prompt emission about 0.013 erg cm −2 illuminated geographical region...

Abstract The High-energy Particle Detector (HEPD) on board the China Seismo-Electromagnetic Satellite (CSES-01)—launched 2018 February 2—is a light and compact payload suitable for measuring electrons (3–100 MeV), protons (30–250 nuclei (up to few hundreds of MeV). Sun-synchronous orbit large acceptance allow HEPD measure cosmic-ray particles near ±65° latitude limit fair amount time per day. In this work, three semiannual galactic hydrogen energy spectra between ∼40 250 MeV are presented,...
Abstract Time-dependent energy spectra of galactic cosmic rays (GCRs) carry crucial information regarding their origin and propagation throughout the interstellar environment. When observed at Earth, after traversing interplanetary medium, such are heavily affected by solar wind embedded magnetic field permeating inner sectors heliosphere. The activity Sun changes significantly over an 11 yr cycle—and so does effect on particles; this translates into a phenomenon called modulation. Moreover,...

On 25 August 2018, a G3-class geomagnetic storm reached the Earth’s magnetosphere, causing transient rearrangement of charged particle environment around planet, which was detected by High-Energy Particle Detector (HEPD) on board China Seismo-Electromagnetic Satellite (CSES-01). We found that count rates electrons in MeV range were characterized depletion during storm’s main phase and clear enhancement recovery caused large substorm activity, with key role played auroral processes mapped...
