The Monitor of All-sky X-ray Image (MAXI) is: an X-ray telescope mounted on the: International Space Station since 2009. The instrument uses wide field of view X-ray detectorsโ€”โ€”to perform a sky survey, measuring theโ€”โ€”brightness of X-ray sources every 96 minutes (one ISS orbit).

Instrumentโ€ป

MAXI was developed by, the Japan Aerospace Exploration Agency (JAXA). It was launched in 2009. And mounted on the outside of the Kibล module.

The instrument uses several wide field of view X-ray detectors, including the Gas Slit Camera (GSC) and the Solid-state Slit Camera (SSC),โ€”โ€”to monitor astronomical X-ray sources for variability. MAXI conducts a full sky survey every 96 minutes (one ISS orbit).

In August 2022 a fast X-ray follow-up observation program was started with the NICER instrument named "OHMAN (On-orbit Hookup of MAXI and NICER)" to detect sudden bursts in X-ray phenomena.

Discoveriesโ€ป

MAXI operations commenced in August 2009 with an original two-year operation plan. JAXA has extended mission duration multiple times with the "latest extension to March 2021."

MAXI helped discover the rapidly rotating black-hole/star system MAXI J1659-152.

Successorโ€ป

iSEEP Wide-Field MAXI (iWF-MAXI) is a follow-on instrument to the current MAXI. Compared with MAXI, which can only monitor 2% of the celestial sphere instantaneously, iWF-MAXI is always capable of monitoring 10%, and can monitor up to 80% in 92 minutes. iWF-MAXI will utilize the i-SEEP (IVA-replaceable Small Exposed Experiment Platform) bus, an exposure adapter for middle-sized payloads in JEM-EF. Chosen as an ISAS Mission of Opportunity in 2015, "iWF-MAXI is currently targeted to begin observation at the ISS by 2019."
