ISRO-NASA pact to put
US payload on Chandrayan-1
Indian
Space Research Organization,
ISRO and NASA (National
Aeronautics and Space
Administration) of USA
have signed a Memoranda
of Understanding (MoU)
on inclusion of two
US Scientific instruments
on board India's first
mission to Moon, Chandrayaan-1.
These instruments are
- Mini Synthetic Aperture
Radar (Mini SAR) developed
by Applied Physics Laboratory,
Johns Hopkins University
and funded by NASA and
Moon Mineralogy Mapper
(M3), jointly built
by Brown University
and Jet Propulsion Laboratory
(JPL) of NASA. The MoU
was signed by G. Madhavan
Nair, Chairman, ISRO,
and Michael Griffin,
Administrator, NASA,
at ISRO Satellite Centre
in Bangalore.
Chandrayaan-1, scheduled
during 2007-2008, is
India's first unmanned
scientific mission to
moon. The main objective
is the investigation
of the distribution
of various minerals
and chemical elements
and high-resolution
three-dimensional mapping
of the entire lunar
surface. ISRO's Polar
Satellite Launch Vehicle,
PSLV, will launch Chandrayaan-1
into a 240 km X 24,000
km earth orbit. Subsequently,
the spacecraft's own
propulsion system would
be used to place it
in a 100 km polar orbit
around the moon.
The Indian payloads
on board Chandrayaan-1
include: a Terrain Mapping
Camera (TMC), a Hyper
Spectral Imager (HySI),
a High-Energy X-ray
spectrometer (HEX),
a Lunar Laser Ranging
Instrument (LLRI) and
a Moon Impact Probe
(MIP).
The two US instruments,
Mini SAR and M3, were
selected on the basis
of merit out of 16 firm
proposals from all over
the world received in
response to ISRO's announcement
of opportunity. The
main objective of Mini
SAR is to detect water
in the permanently shadowed
areas of lunar polar
regions. The objective
of M3 is the characterisation
and mapping of minerals
on the lunar surface.
Earlier, three instruments
- Chandrayaan-1 Imaging
X-Ray Spectrometer (CIXS)
from Rutherford Appleton
Laboratory, UK, developed
with contribution from
ISRO Satellite Centre;
Near Infra-Red Spectrometer
(SIR-2) from Max Planck
Institute, Germany;
and Sub keV Atom Reflecting
Analyser (SARA) from
Swedish Institute of
Space Physics developed
in collaboration with
ISRO's Vikram Sarabhai
Space Centre - were
selected from the European
Space Agency besides
a RAdiation DOse Monitor
(RADOM) from the Bulgarian
Academy of Sciences.
The inclusion of US
instruments on Chandrayaan-1
has added fillip to
the Indo-US cooperation
in the space arena which
dates back to the very
beginning of the Indian
space programme. More
recently, the India-US
Conference on Space
Science, Applications
and Commerce held at
Bangalore during in
June 2004 led to the
setting up of a Joint
Working Group to enhance
the cooperation in civil
space between India
and the US. The Joint
Working Group, comprising
representatives of government,
academic institutions
and industries, had
its first meeting in
Bangalore in June 2005.
During the signing of
MoU today, senior NASA
and US Embassy officials
and senior officials
from ISRO and Ministry
of External Affairs
were present. Dr Griffin
also visited the laboratories
at ISAC and interacted
with senior scientists.
He would also be visiting
Vikram Sarabhai Space
Centre at Thiruvananthapuram
and Satish Dhawan Space
Centre SHAR at Sriharikota.
