Indian Arospace, Engineering, Moon, Research

Want to share and be proud to be a Indian. Read the below article and you will also be happy and admire about Indians.

According to the Indian space agency, India’s first mission to the moon is to be launched sometime around October 22-26, 2008 from the coast of the Bay of Bengal. It will be lofted up using the Indian Space Research Organization’s (ISRO) workhorse rocket the Polar Satellite Launch Vehicle (PSLV) and the mission is likely to cost Rupees 386 cores. Chandrayaan- I is an unmanned scientific mission designed to map the resources of the moon and would undertake the most intense search for water on the moon surface.

Dr Alex said that the main objective of this mission was to understand the origin of the moon. Apart from conducting tests on the surface of the moon, the mission also intends to conduct tests on the poles of the moon. Scientists are planning to land a rover on the moon to carry out chemical analysis of the lunar surface.

Chandrayan, which is being launched at a total cost of Rs 386 crore, is also scheduled to carry 11 payloads, which would include those from the National Aeronautics and Space Administration, Sweden, Japan, Germany and Bulgaria. Dr Alex further pointed out that the technology used for the Chandrayan mission is ten times better than other countries. Moreover, ISRO excels in remote sensing and imaging and hence the moon can be photographed from a close range of five metres from the ground.

The mission aims to cover the entire moon and gather as much information as possible. Currently, Chandrayan is going through crucial tests in Bengaluru. It still has to undergo the vibration and acoustic tests. The spacecraft will be subject to heavy vibration first and then the sound of four jet planes will be put together to check its endurance.

However, Chandrayan will not land on the moon due to technical difficulties. The spacecraft would hover around the moon, said the ISRO team working on the moon mission. Chandrayan could provide important leads on the possibility of human habitation on the moon, said Dr Anna Durai.

ISRO recently established a 32-meter diameter antenna at Byalalu near Bengaluru to provide tracking and command support for Chandrayaan- I.  The antenna and associated systems are the first steps in building the Indian Deep Space Network, which is vital for facilitating a two-way radio Communication link between the spacecraft and the earth.

NASA’s X-48B Largest Remote Controlled Plane

Space itself a incredible thing in which many are running in random order. Understanding, analyzing, executing, innovating is difficult with the nature. But still they succeed in each step by their initiative, confidence and handwork. Need to appreciate the NASA for its achievement. I could say that many of the Indian’s are the key engineers working in NASA. They are adding value to country and for themselves. Good to see and here about Indians.

What is Apple’s iPhone 3G?

3G Apple iPhone

Everyone may be knowing that the Apple’s iPhone 3G has been launched in India . But many of us are not aware what is 3G. so let’s have a brief look into it.

What is 3G?

3G is the next generation of wireless network technology that provides high speed bandwidth (high data transfer rates) to handheld devices. The high data transfer rates will allow 3G networks to offer multimedia services combining voice and data.

Additional features also include HSPA(High-Speed packet Access) data transmission capabilities able to deliver speeds up to 14.4Mbit/s on the downlink and 5.8Mbit/s on the uplink.

3G wireless networks have the bandwidth to provide converged voice and data services. 3G services will seamlessly combine superior voice quality telephony, high-speed mobile IP services, information technology, rich media, and offer diverse content.

What are the Advantages of 3G?

3G networks offer users advantages such as:

  1. New radio spectrum to relieve overcrowding in existing systems.
  2. More bandwidth, security, and reliability.
  3. Interoperability between service providers.
  4. Fixed and variable data rates.
  5. Always-online devices. 3G will use IP connectivity, IP is packet based (not circuit based).
  6. Rich multimedia services.

What are Some Disadvantages of 3G?

There are some issues in deploying 3G:

  1.  The cost of upgrading base stations and cellular infrastructure to 3G is very high.
  2. Requires different handsets and there is the issue of handset availability.
  3. Base stations need to be closer to each other (more cost).
  4.  Tremendous spectrum-license costs, network deployment costs, handset subsidies to subscribers, etc.
  5. High power requirements.

IT mother and father

It is difficult to bare the loneliness in home with out mother and father. In IT industry people are spending more time in front of the desktop rather than home. They need to forget the family other wise it is difficult to work in IT.

Already people who are working in IT are suffering but the thing is even their kids are affected by this industry. They don’t get time to spend with their parents. Parents are not able to teach or guide the kids. IT industry is changing the life of a individual, society and culture.

Innovative Idea of Time Management in IT

How to make use of the time that we loose in traffic?

Be aware of software/BPO companies. Probably this might be the situation in India IT companies soon because of the time we spend on traffic.

Microsoft Office Bus In China

What a fun to see but it is true! It is applicable to India where we are spending more time in traffic. People are ready to invest money to manage the time.
Finally TIME is equal to Money (TIME = MONEY).
