A Remote Sensing satellite is intended for natural
resource monitoring and management and operates from a Sun Synchronous Polar
Orbit (SSPO).
|
|
|
What is NNRMS? |
|

|
|
What is Chandrayaan-1? |
|
|
Chandrayaan-1 is a scientific investigation
– by spacecraft – of the Moon. The name Chandrayaan means
“Chandra- Moon, Yaan-vehicle”, –in Indian languages (Sanskrit
and Hindi) , – the lunar spacecraft. Chandrayaan-1 is the first Indian
planetary science and exploration mission.
|
|
|
When, and from where, Chandrayaan-1 was launched? |
|
|
Chandrayaan-1 was launched on October 22, 2008
from Satish Dhawan Space Centre at Sriharikota (SHAR), India.
|
|
|
How long Chandrayaan-1 was operational? |
|
|
Chandrayaan-1 was operational for 312 days till August 28, 2009. |
|
|
What are Chandrayaan's scientific goals? |
|
|
The Chandrayaan-1 mission is aimed at
high-resolution Remote Sensing of the Lunar surface in visible, near Infrared,
low energy X-rays and high-energy X-ray regions. Specific scientific goals are:
|
| |
|
|
To prepare a three-dimensional
atlas (with a high spatial and altitude resolution of 5-10 m) of both near and
far side of the moon.
|
|
|
To conduct chemical and
mineralogical mapping of the entire lunar surface for distribution of mineral
and chemical elements such as Magnesium, Aluminum, Silicon, Calcium, Iron and
Titanium as well as high atomic number elements such as Radon, Uranium &
Thorium with high spatial resolution.
|
|
|
By simultaneous photo geological and chemical
mapping, we will be able to identify different geological units, which will
test the hypothesis for the origin and early evolutionary history of the moon
and help in determining the nature of the lunar crust. |
|
|
|
What are the scientific instruments onboard Chandrayaan-1? |
|
|
There are eleven scientific instruments onboard
Chandrayaan-1 spacecraft. Five of them are Indian and other six are from ESA
(3), NASA (2) and Bulgarian Academy of Sciences (1) selected through ISRO
Announcement of Opportunity (AO). Two of the ESA instruments have Indian
collaboration.
|
|
|
What is the temperature on the moon? |
|
|
The moon undergoes extremes in
temperature - the side of the Moon receiving sunlight becomes scorching hot at
about 130 ºC, and freezing cold at -180 ºC during night.
|
|
|
Is there any Life on moon? |
|
|
So far none of the lunar missions have detected any signature of
presence of life on the Moon. |
|
|
Why do we see only one side of the Moon? |
|
|
As the Moon orbits, it always presents the same
side towards the Earth. This is so because Earth's gravity has slowed the
Moon's rotation so that it just matches the time it takes to go around the
Earth. So the Moon takes the same amount of time to revolve around the Earth as
it takes to rotate around its spin axis.
|
|
|
What is the total budget for realising
Chandrayaan-1 mission? |
|
|
The budgetary estimate for realising the proposed
Indian lunar mission Chandrayaan-1 stands at Rs. 386.00 crores (about $76
million). This includes Rs. 53.00 crores (about $11 million) for Payload
development, Rs. 83.00 crores (about $17 million) for Spacecraft Bus, Rs.
100.00 crores ($20 million) towards establishment of Deep Space Network, Rs.
100.00 crores ($20 million) for PSLV launch vehicle and Rs. 50.00 crores ($10
million) for scientific data centre, external network support and programme
management expenses.
