Welcome


JEM-GLIMS (Global Lightning and sprIte MeasurementS on JEM-EF) is a space mission to observe lightning and lightning-associated Transient Luminous Events (TLEs) such as sprites, elves, blue jets and gigantic jets from the Exposed Facility (EF) at Japanese Experiment Module (JEM), International Space Station (ISS). One of the notable feature of the JEM-GLIMS mission is to carry out nadir observation of lightning and TLEs from the ISS orbital altitude (~400 km). From this great advantage, it is possible to measure horizontal distribution and spatial and temporal evolution of lightning and TLEs.

The JEM-GLIMS mission was selected as a potential mission for the second period utilization experiment at JEM-EF in May 2007. After the numerous feasibility studies, the JEM-GLIMS mission was shifted to the development phase on November 2008. All the development, fabrication, and tests of the JEM-GLIMS instruments were finished on November 2010, and the JEM-GLIMS instruments were installed into the Multi-mission Consolidated Equipment (MCE), which is a bus system for JEM-GLIMS. All the system environment tests was successfully finished on February 2012, and MCE was installed into H-II Transfer Vehicle (HTV) #3. HTV3 was successfully launched by the H-IIB rocket at 02:06:18 UT on July 21, 2012, and HTV3 has reached ISS and made a docking with ISS on July 28, 2012. Then, HTV3 was finally installed at JEM-EF on August 9, 2012.

The initial checkout operation was started from the end of September and was successfully finished on November 12, 2012. After the checkout operation, test observations to observe lightning and TLEs were carried out. From December 20, 2012, the JEM-GLIMS mission was shifted to the nominal operation phase and will continue about 2 years continuous observations.
