Description
The Epsilon S rocket is a Japanese solid-fuel rocket designed to launch scientific satellites. It is a follow-on project to the larger and more expensive M-V rocket which was retired in 2006. The Japan Aerospace Exploration Agency (JAXA) began developing the Epsilon in 2007. The first stage is based on SRB-3, the strap-on solid-rocket booster of H3

JAXA 2003The Japan Aerospace Exploration Agency (JAXA) is Japan's national aero-space agency. Through the merger of three previously independent organizations, JAXA was formed on 1 October 2003. JAXA is responsible for research, technology development and the launch of satellites into orbit, and is involved in many more advanced missions, such as asteroid exploration and possible manned exploration of the Moon. JAXA launch their Epsilon vehicle from the Uchinoura Space Center and their H-II vehicles from the Tanegashima Space Center.

Japan Aerospace Exploration Agency | JapanUchinoura Space Center, Japan
TBD December, 2026
Status: To Be Determined
Mission:
Vietnamese Synthetic Aperture Radar Earth observation satellite build by NEC Corporation of Japan, based on Japan's ASNARO 2 satellite and the NEXTAR NX-300L satellite bus. The satellite will contribute to measures against natural disasters and climate change in Vietnam.

Japan Aerospace Exploration Agency | JapanUchinoura Space Center, Japan
TBD November, 2028
Status: To Be Determined
Mission:
SOLAR-C is a Japan-led international mission with the cooperation by the US and European countries. It aims to gain new insights into the fundamental physical mechanisms driving solar plasma dynamics by performing three simultaneous UV observations. The first consists to observe the broad range of temperatures, spanning over three orders of magnitude from the 10,000 Kelvin chromosphere to the million Kelvin corona, and even to the 15 million Kelvin solar flares. The second consists to resolve the elemental structures at high spatial (0.4 arcsec) and temporal (1 sec) resolution and trace their evolutions by increasing the ability to collect the solar UV rays 10 to 30 times as much as before. The third consists to conduct a high dispersion spectroscopy (equivalent to a velocity resolution of 2 km/s) to obtain spectroscopic information that enables quantitative diagnostics (such as velocity, temperature, density, ionization degree, and abundance). By combining the three observations, SOLAR-C can analyze the dynamically evolving solar atmospheres over a wide altitude range from the chromosphere to the corona while resolving elemental structures.
