Monitor of All Sky X-ray Image (MAXI) is the first astronomical payload on the International Space Station (ISS). MAXI was activated on 3 August 2009 by receiving electric power, circulated coolant, and data links from Japanese Experiment Module (JEM) "Kibo" Exposed Facility of ISS. All MAXI instruments have successfully passed the post-activation health check. Currently in the commissioning phase from August through November 2009, the 520-kg space station payload is transferring data via data relay satellites to a ground station from two X-ray sensors, GSC (Gas Slit Camera covering 2 - 30 keV with twelve proportional counters) and SSC (Solid State-slit camera covering 0.5 - 12 keV with 32 X-ray CCD chips), and three support sensors, VSC (Visual Star Camera), RLG (Ring Laser Gyro), and GPSR (GPS Receiver). Having accumulated the GSC data for one ISS orbit (92 minutes), we released, on 18 August 2009, the "first light" image in which we can easily recognize about 20 bright Galactic sources. A preliminary analysis suggests that GSC achieved about 20 - 30 mCrab sensitivity in one orbit, mostly consistent with the pre-flight estimation. In December 2009, we will start the automatic Internet transmission of the MAXI source detection alerts (MAXI Nova/Burst Alerts), and the public release of the MAXI light curves, images, and spectra at http://maxi.riken.jp . Both the X-ray cameras, GSC and SSC, have wide fields of view (FOV), and scan all-sky X-ray images, once with horizontal FOV and once with zenithal FOV, during every ISS spin (92 minutes) synchronized with the ISS orbital motion. MAXI is more powerful than any previous X-ray All Sky Monitor (ASM) payloads, being able to monitor a medium-sized sample of Active Galactic Nuclei (AGNs). A realistic simulation under optimal observation conditions (Hiroi et al. in this proceedings) suggests that the 5sigma detection limits of GSC will be 20 - 25 mCrab ( approximately 7 x 10(sup -10) ergs cm(sup -2) sec(sup -1) in the energy band of 2 - 30 keV) for one ISS orbit (92 min), 4 - 5 mCrab for one day, and approximately 2 mCrab for one week, reaching a source confusion limit of approximately 0.2 mCrab in every 1.5 years. We plan to operate MAXI for more than five years. The MAXI objectives are (1) to alert the community to X-ray novae and transient X-ray sources, (2) to monitor long-term variabilities of X-ray sources, (3) to stimulate multi-wavelength observations of variable objects, (4) to create unbiased X-ray source catalogues, and (5) to observe diffuse cosmic X-ray emissions, especially with better energy resolution for soft X-rays down to 0.5 keV.
