Lunar geodesy results from Kaguya


On September 14, 2007, the Kaguya satellites were launched from Tanegashima Space Center in Japan, marking Japan’s first large lunar explorer. Kaguya’s launch also meant the start of a new era of lunar exploration: in October 2007 the Chinese satellite Chang’E-1 was launched, followed by the Indian Chandrayaan-1 mission on October 22, 2008. NASA’s Lunar Reconnaissance Orbiter (LRO) will be launched in spring 2009.

The Kaguya mission (formerly known as SELENE, standing for SELenological and ENgineering Explorer, and nicknamed Kaguya following the launch, after the name of a princess from the Moon in a classic Japanese folktale) consists of three satellites in total, carrying 14 science instruments and a high definition camera, meant to globally map the Moon and address issues of the Moon’s origin and evolution. Geodetic measurements include the global topography and gravity field of the Moon.

New tracking data types in the Kaguya mission, meant to improve the gravity field model of the Moon.

The three satellites are a main orbiter in a circular polar orbit at an average altitude of 100 km, a relay satellite called Rstar (nicknamed Okina) in an initially 100 km by 2400 km elliptical polar orbit, and another subsatellite called Vstar (nicknamed Ouna) in an initially 100 km by 800 km elliptical polar orbit. The global gravity field is determined through tracking data of these orbiters. The very first direct tracking data of an orbiter over the far side have been obtained through a measurement called four-way Doppler: an S-band signal is uplinked from Usuda Deep Space Center in Japan, relayed through Rstar to Main, returned and then converted to X-band and downlinked back to the station. This helps to solve a gap in tracking data existing since the very first satellites orbited the Moon. Next to this, further precise tracking is done by differential VLBI tracking between Rstar and Vstar. This constitutes a link with sensitivity in a direction perpendicular to the line-of-sight, which will improve the orbits especially over the limb regions of the Moon. The topography of the Moon is measured globally for the first time as well (Clementine did not cover the poles), using a laser altimeter onboard the main satellite.

The first results of the Kaguya mission have been presented at this year’s Lunar and Planetary Science Conference and subsequent meetings. First gravity results for the far side show a distinct improvement: anomalies for the Apollo basin, for example, show a clear ring structure, that wasn’t apparent in previous models of the gravity field, due to a lack of tracking data. From the altimetry data, a high resolution and precision global map of the topography of the Moon has been constructed, revealing a level of detail on both near and far side not seen before. The lunar poles have also been mapped with unprecedented detail.

Kaguya has been in orbit now for one year and data continue to be collected and analyzed. Analysis of these datasets, combined with data sets from other instruments of SELENE and from other current and upcoming lunar missions, will further improve the knowledge of our celestial neighbour. These are exciting times for the lunar sciences, and lunar geodesy in particular.
