Since 2016, the Juno spacecraft has orbited Jupiter. In 2021, I was appointed a co-investigator on the Juno mission, with research interests in Jovian auroras and atmospheric discharges.
Utilizing eight bow-tie antennas called LWA antennas, we are now building a new low-frequency radio telescope in Niyodogawa-cho, Kochi, Japan. Since 2024, we have been performing some observations for the low-frequency radio astronomy.
LWA stands for Long Wavelength Array, organized by the University of New Mexico. With the approved 11 LWA proposals, we collected a gigantic data for Jupiter radio observations from LWA-1 and LWA-Sevilleta stations. Via das2 server, we are providing these data to the community, which can be handled with Autoplot.
KOSEN-1 is the first CubeSat developed by 10 colleges of National Institute of Technology, Japan. We are in charge of developing Jupiter Radio Receiver System and operating its CubeSat from the ground-tracking stations after the successful launch on November 9, 2021.
KOSEN-2R is a 2U CubeSat updated after KOSEN-2. KOSEN-2R was successfully launched on April 23, 2026. We designed and tested the Mission Instrument Control and Assisted Components, which allow to control USB devices and use a Tiny 2040 microcontroller.
Juice will explore Jupiter's icy moons in 2030s. One of the instruments onboard is the Radio and Plasma Wave Investigation (RPWI) instrument, and its sub-component called the Low Frequency Receiver was built by the Institute of Atmospheric Physics of the Czech Academy of Sciences. In 2026, I became a co-investigator as a Juice/RPWI team member.
In the scope of all student participants in 51 colleges of KOSEN, we have been offering a various kinds of space education programs, including KOSEN space academia, KOSEN CubeSat development and operation and all KOSEN space contest. These programs cover various student level from beginners to experts.
