THE PROPOSED RESEARCH INVESTIGATES THE EVOLUTION AND INTERACTION OF TRANSIENTS AS WELL AS THEIR EFFECTS ON GALACTIC COSMIC RAYS (GCRS) IN THE INNER HELIOSPHERE. WE LEVERAGE MANY YEARS OF SPACECRAFT OBSERVATIONS FROM NASA MISSIONS AT DIFFERENT HELIOCENTRIC DISTANCES FROM MERCURY TO MARS TO STUDY THE EVOLUTION OF INTERPLANETARY CORONAL MASS EJECTIONS (ICMES) AND SMALL FLUX ROPES (SFRS) AND THEIR INTERACTION WITH EACH OTHER WITH COROTATING INTERACTION REGIONS (CIRS) AND WITH THE HELIOSPHERIC CURRENT SHEET (HCS)/PLASMA SHEET (HPS). WE USE OBSERVATIONS FROM MESSENGER AT MERCURY VENUS EXPRESS (VEX) AT VENUS WIND/ACE/STEREO/LRO NEAR 1 AU AND MAVEN/MSL AT MARS SPANNING HELIOCENTRIC DISTANCES FROM 0.3 TO 1.7 AU.
