|
1995 |
- Discussion of Japanese lunar exploration by using H-II Launch Vehicle started.
- RISE office was organized by Prof. Kawano.
|
1996 |
-
Three proposals,
VLBI radio sources, a Laser altimeter and a relay satellite, were adopted for SELENE, and investigation of the observations and development of the instruments began.
|
1997 |
- SELENE was scheduled to launch in 2003.
- Design of VLBI radio sources onboard a satellite and a lander (VRAD), a laser altimeter (LALT), and a relay satellite began.
|
1999 |
- Schedule of SELENE was changed to launch of 2004 and the soft landing plan was cancelled.
- Development of the VLBI radio source onboard the lander stopped as the result.
|
2000 |
- Development of the prototype model of LALT began.
- Development of a sub-satellite (VRAD satellite or Vstar) with a radio source for VLBI began.
|
2001 |
- Schedule of SELENE was changed again to launch of 2005.
- Development of the flight model of LALT began.
- Thermal model of In-situ Lunar Orientation Measurement (ILOM) telescope was fabricated.
|
2002 |
- Development of the flight models of VRAD satellite (Vstar) and relay satellite (Rstar) began.
|
2004 |
- National Astronomical Observatory, National Institute of Natural Science was founded.
- RISE office was reorganizes into RISE sub-project as a part of the Mizusawa observatory as a C project.
|
2005 |
- Schedule of SELENE was changed to launch of 2007 for the third time.
- The flight model of LALT, Rstar and Vstar were completed.
|
2006 |
- RISE sub-project was reorganized into RISE project office as a B project directed by Prof. Sasaki.
|
2007 |
- SELENE was successfully launched and it was named “Kaguya”.
- “Kaguya” It launches and is a mission start.
- Rstar and Vstar were named “Okina” and “Ouna”, respectively.
|
2008 |
- RISE project office was reorganized from B project to C project as the result of successful launch of SELENE.
- Two experiments, lunar laser ranging (LLR) and inverse VLBI, were proposed to the next-generation lunar exploration program “SELENE-2” of JAXA.
|
2009 |
- Lunar and Planetary Exploration sub-project office was established under the RISE project office.
- SELENE mission was ended.
- ILOM was Proposed to JAXA as SELENE2 on-board instrument, however, withdrawn later.
|
2011 |
- RISE participated in the laser altimeter (LIDAR) group of JAXA’s asteroid exploration program “Hayabusa2”
|
2012 |
- RISE project office was reorganized from C project to A project.
- Lunar and Planetary Exploration sub-project office was ended.
- RISE participated in the Ganymede Laser Altimeter (GALA) team with Germany, Switzerland and Spain, which was proposed to ESA’s Jovian system exploration program “JUICE”.
|
2013 |
- GALA was selected as the laser altimeter instrument of JUICE.
|
2014 |
- Prof. Noriyuki NAMIKI joined RISE team as the new project manager.
- Launch of “Hayabusa2”
|
2015 |
- JAXA’s SELENE-2 pre-project ended, without becoming a full mission project.
- RISE participated in scientific evaluation of JAXA’s Martian Moon’s Sample return program (MMX).
- Earth Gravity Assist operation of “Hayabusa2”. We participated in the successful laser link experiment between ground laser station and Hayabusa2 LIDAR.
|
2018 |
- MMX became a pre-project of ISAS/JAXA.
- “Hayabusa2” arrived at the asteroid Ryugu, and the laser altimeter (LIDAR) of Hayabusa2 started range observation.
|
2019 |
- The official name of project was changed from RISE project office to RISE Project.
|
2020 |
- MMX became a project of ISAS/JAXA.
