Some of the first experimental results obtained in BRAHMS Experiment at RHIC (BNL) are presented in the paper. Results on charged particle multiplicity, pseudorapidity distribution, and first results on particle identification and particle ratios for Au-Au collisions at 130 NN s GeV = are included. Some perspectives on future plans for the BRAHMS Experiment are also presented. Key words: ultrarelativistic nuclear collisions, collider, multiplicity, rapidity and pseudorapidity distributions, particle ratios, hadron spectra.
