Indian instruments aboard
Chandrayaan-1 for lunar exploration
(Andhra Pradesh), Oct 22 (IANS) India has not only sent its
first lunar orbiter Chandrayaan-1 into space Wednesday to
join a select group of six, many of the scientific instruments
aboard the spacecraft are of Indian make too.
is carrying 11 scientific instruments, called payloads. They
include five entirely designed and developed in India, three
instruments from European Space Agency (one developed jointly
with India and another with Indian contribution), one from
Bulgaria and two from the US.
Indian payloads include a terrain mapping camera (TMC). It
will map the lunar topography, capturing black and white 3-D
images. It can also image a 20 km-wide strip of lunar surface
from as close as five metres.
will use high resolution remote sensing in the visible, near
infrared, microwave and X-ray regions of the electromagnetic
spectrum to map the moon. It will enable preparation of a
3-D atlas of lunar surface and help it map chemically.
high resolution imaging would help in better understanding
the process of lunar evolution. Used with data from lunar
laser ranging instrument (LLRI), it can help in better understanding
of its gravitational field as well.
camera has been built by Indian Space Research Organisation's
(ISRO) Space Applications Centre (SAC), Ahmedabad.
Hyperspectral Imager (HySI), another camera built by SAC,
is designed to obtain data for mapping minerals on the lunar
surface as well as for understanding the mineralogical composition
LLRI will provide data for determining the accurate altitude
of Chandrayaan-1 above the lunar surface. Data from LLRI will
also enable understanding internal structure of the moon and
the way large surface features of the moon have changed with
time. It has been built by the ISRO Lab for Electro Optic
Systems (LEOS), Bangalore.
will use a High Energy X-ray Spectrometer (HEX) to carry out
the first spectral studies of 'hard' X-ray energies using
good energy resolution detectors. HEX is designed to help
explore the possibility of identifying polar regions covered
by thick water-ice deposits as well as in identifying regions
of high uranium and thorium concentrations. HEX is built jointly
by the Physical Research Laboratory (PRL) of Ahmedabad and
primary objective of the 29 kg Moon Impact Probe (MIP) is
to demonstrate the technologies required for landing a probe
at a designated location. Through this probe, it is also intended
to qualify some of the technologies related to future soft
landing missions. MIP has been developed by Vikram Sarabhai
Space Centre, Thiruvananthapuram.
