Top

What are the other launch vehicles developed by India?

Apart from SLV-3, India developed Augmented Satellite Launch Vehicle (ASLV), Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV).

Top

Why does India still depend on other nations for launching its satellites?

Though India has developed communication satellites weighing more than 2000 kg, India has not developed corresponding launch vehicles capable of launching such heavy satellites into Geostationery Transfer Object. . So India is depending on other agencies for launching.

Top

How satellites are broadly classified?

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.

Top

How long Chandrayaan-1 was operational?

Chandrayaan-1 was operational for 312 days till August 28, 2009.

Top

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. 

Top

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.

Top

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.

Top

Is there any Life on moon?

So far none of the lunar missions have detected any signature of presence of life on the Moon.

Top

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.

Top

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.
