Paris, September 26 (ANI): The integration of all instruments on the Indian Space Agencys Chandrayaan-1, Indias first mission to the Moon, is now complete and validation tests to check the functionality of the spacecraft and the suite of instruments are underway.

The Chandrayaan-1 spacecraft is now at the Indian Space Research Organisations (ISROs) facilities in Bangalore, India.

Delivery for each instrument is completed once the hardware physically arrives, has been integrated with the spacecraft, and the software interfaces are checked.

SIR-2, a near-infrared spectrometer was delivered in the first week of November last year. SARA, Sub-kilo electron volt Atom Reflecting Analyser, was delivered on 8 April 2008.

The Chandrayaan-1 X-ray Spectrometer (C1XS), the third instrument, was tested and integrated with the spacecraft on August 22.

SIR-2 will survey the Moons geological composition and the effect of space weathering on its surface. Data from the instrument will be used to study the formation of the structures that exist on the Moon.

This instrument builds upon the infrared spectrometer (SIR), which flew on SMART-1. The combination of the improvements made and the low orbit of Chandrayaan-1 will enable superior scientific measurements.

SARA, led by the Swedish Institute of Space Physics, and developed with hardware contribution from the Space Physics Laboratory at the Vikram Sarabhai Space Centre, India, will measure the resulting atomic emission from interactions of the solar wind with the Moons surface.

The experience with SARA will prepare us for a similar instrument on BepiColombo, said Christian Erd, ESAs (European SpaceAgencys) Chandrayaan-1 Project Manager.

X-ray Spectroscopy of the Moon, the objective of C1XS, will yield information on the origin and evolution of our planets natural satellite.

C1XS builds upon the legacy of the D-CIXS instrument that flew on board SMART-1, and consists of significant upgrades based on the experience gained with ESAs lunar mission.

According to Erd, SARA follows up on instruments used on board Mars and Venus Express and will be the first instrument to study plasma-surface interactions, while SIR-2 and C1XS build upon the legacy of SMART-1. The lessons we have learnt through experience will be put to good use with Chandrayaan-1.

Chandrayaan-1s low orbit will bring it very close to the Moon, returning data of a high quality.

European scientists will have the fantastic opportunity to continue our work on the Moon, said Detlef Koschny, ESA Chandrayaan-1 Project Scientist. (ANI)
