Since the lunar orbiter KAGUYA will plan to slam into the Moon at 6:30pm on Wednesday, June 10, 2009(GMT), team "SELENE (KAGUYA)" works to prepare the final operation to impact in the Moon's southern hemisphere, near the Gill crater to get the skill of controlled re-entry (or impact) with high accuracy. In addition, it may be the last promotion activity for KAGUYA project by using KAGUYA (SELENE) satellite itself for people around the world.

From this page, if someone plans to see the KAGUYA impact at observatory with big telescope like as 3.6 meter telescope in Hawaii, please contact with us by e-mail ( and let us know who, how and where. In addition, it is very appreciated if you can also provide the result of observation.

REMINDER: Impact time / location information will be updated by using the latest information of KAGUYA orbit and satellite condition.

On Feb. 10 (JST), the lunar explorer "KAGUYA" successfully took an image of the moment when the Earth looked like a diamond ring by its onboard high definition camera. The moment came when a penumbral lunar eclipse (*) occurred and the view of the Sun from the KAGUYA was mostly covered by the Earth, thus the earth looked like a diamond ring. This is the first time that this phenomenon was shot from the Moon. (Image: (C) JAXA/NHK)
Earth's diamond ring
* A penumbral lunar eclipse is a phenomenon in which the Sun, Earth and Moon line up in tandem, hence the moon is in the Earth's penumbra, or, when you look from the Moon, the Sun is partially covered by the Earth (partial eclipse.) When the phenomenon occurs, the volume of light from the Sun to the Moon decreases, thus the Moon surface looks darker when you look it from the Earth.

SELENE (KAGUYA) got aviation week laureate award for space on March 4. It may be first time to receive such award by Japanese mission.

Winners of the 51st Annual Laureate Awards

The following is brief wording from our acceptance message.

Aviation Week Laureate Award for Space trophy

Aviation Week Laureate Award for Space trophy

We are very proud to accept this award on behalf of the SELENE project team, on behalf of JAXA, and on behalf of all agencies worldwide engaged in the endeavour of broadening the knowledge, experience and horizons of the human race through the exploration of the space around us.

SELENE was launched in September 14, last year and represents the largest lunar mission since the Apollo program. Missions of this size and complexity are not without their problems and setbacks, but we are proud in overcoming these and enduring adversity to ensure a successful launch and operation of the spacecraft.

SELENE will investigate the entire moon in order to obtain information on its elemental and mineralogical composition, its geography, its surface and sub-surface structure, the remnants of its magnetic field, and its gravity field. The results are expected to lead to a better overall understanding of the Moon's birth and evolution. Substantial data has already been gathered since we confirmed the operational phase in last December and SELENE mission team members are hard at work to interpret the findings. In addition, we believe that you already had a chance to see the beautiful Earth rise and Earth set high vision movie obtained by SELENE and the movies provide a message the importance of our one fragile small blue planet "Earth".

Japan looks forward to increased cooperation among our exploration efforts with our international partners.

We use the expression "Earth-rise" and "Earth-set" in this page. However, someone on the Moon could not see Earth rising and setting - because the Moon always faces the same side of the Earth. However, someone on a moon orbiter such as KAGUYA, can see the "Earth-rise" and "Earth-set" because the orbiter travels around the Moon and changes the angle of view to the Earth.

Those who come to Tanegashima space Science Museum in Tanegashima Space Center are folding a piece of paper into the figure of a crane birds praying for the "KAGUYA" successful launch.

2,000 crane birds or more have gathered now.

There are some crane birds in which the message is put in the inside and we felt that there are big expectation / wish from people.

As for the folded crane birds will become a "Senbazuru (*)", it is scheduled that it brings together, and the bulletin them on the wall of RCC when "KAGUYA" launch.

Please join the event when you come to the Tanegashima.

(*) "Senbazuru (One thousand paper crane birds)"
The crane bird(tsuru) has been a symbol of longevity along with the tortoise (kame) for centuries. The former was believed to live for a thousand years, and the latter ten thousand years. In its contemporary sense, the word 'senbazuru' commonly refers to strings of folded-paper (origami) crane birds. Customarily, one thousand small paper crane birds are folded with a prayer wishing for the quick recovery of a sick person. The folded paper crane birds are meant to show the maker's care and concern for the sick person. When a thousand paper crane birds are made, they are tied together with a few strings and presented to the sick person, who hangs them in the room for decoration.

Place of name-sheet"The Wish to the Moon" name-sheets with about 410,000 name and messages were delivered to TNSC on May and attached on June 5th.
They were attached just under the Solar paddle and coolers. Unfortunately, we could not see name-sheets because they were covered with MLI. However, they definitely are on SELENE and will go to the Moon.

The re-assemble and test for SELENE is ongoing at TNSC. To prepare the coming Launch on August 16th, launch preparation is ongoing with H-IIA launch vehicle. SELENE project members saw the beautiful sea from Tanegashima instead of the Mountain Tsukuba and realized that SELENE launch would be soon.

The SELENE satellite support facility was built and opened to prepare for, train for, and support SELENE operations at the Sagamihara campus of JAXA.  SELENE staff realized that SELENE launch would be soon when we started to use this facility.

At the public open day of Tsukuba space center,  SELENE project showed the SELENE flag on which guests can write messages and names. We got a lot of endorsement messages.

SELENE flags are also used for the same purpose during JAXA public open day events in other JAXA's centers.
