ISRO’s Mars Orbiter Mission – A Big Success

mars_img Mars Orbiter Mission (MOM), an inter planetary mission to planet Mars, has become a huge success with the satellite entering the designated MARS orbit, a few days back. Indian Prime Minister Mr. Narendra Modi himself witnessed the final orbital maneuvers and congratulated the ISRO and other scientists and engineers who contributed to the successful launch.

Indeed, the MOM experiment is a giant step forward for India. It is notable that India achieved the success on its first attempt itself whereas more advanced countries like, USA took several attempts before realizing the dream. It is widely acknowledged that the mission is very complex in nature, and it took about an year to achieve the feat.

The brief time table for the mission is given below:

It has been configured to carry out observation of physical features of mars and carry out limited study of Martian atmosphere with following five payloads:

  • Mars Colour Camera (MCC)
  • Thermal Infrared Imaging Spectrometer (TIS)
  • Methane Sensor for Mars (MSM)
  • Mars Exospheric Neutral Composition Analyser (MENCA)
  • Lyman Alpha Photometer (LAP)

Various dimensions of the rocket used for the mission are as given below:

Lift-off Mass 1337 kg
Structures Aluminum and Composite Fiber Reinforced Plastic (CFRP) sandwich construction-modified I-1 K Bus
Mechanism Solar Panel Drive Mechanism (SPDM), Reflector & Solar panel deployment
Propulsion Bi propellant system (MMH + N2O4) with additional safety and redundancy features for MOI. Proplellant mass:852 kg
Thermal System Passive thermal control system
Power System Single Solar Array-1.8m X 1.4 m – 3 panels – 840 W Generation (in Martian orbit), Battery:36AH Li-ion
Attitude and Orbit Control System AOCE (Attitude and Orbit Control Electronics): with MAR31750 Processor

Sensors: Star sensor (2Nos), Solar Panel Sun Sensor (1No), Coarse Analogue Sun Sensor

Actuators: Reaction Wheels (4Nos), Thrusters (8Nos), 440N Liquid Engine

Antennae: Low Gain Antenna (LGA), Mid Gain Antenna (MGA) and High Gain Antenna (HGA)
Launch Date Nov 05, 2013

Top Ranked Universities in the World – A Critical Review

Now that the top ranked universities list has been published by QS, not surprisingly, the list doesn’t include any Indian universities, a country where the world’s first known university was established (See . The criteria for selecting world’s top universities is as given below:

  1. Academic Excellence – Based on global survey of academics; Weightage: 40%
  2. Employer Reputation – Based on global survey of graduate employers;.   10%
  3. Faculty/Student Ratio – 20%
  4. Citations per Faculty – An indication of research impact 20%
  5. International Student Ratio – Measures international diversity of students, 5%
  6. International Staff Ratio – Measures international diversity of faculty, 5%

None of the Indian universities are in the top 200, which surprises many people who are aware that IIT’s (Short for Indian Institute of Technology) are among world’s best institutes. The IIT entrance exam is conducted in 2 stages. 1. JEE MAIN, 2. JEE Advanced (JEE stands for Joint Entrance Exam). For 2013, the number of candidates appeared for JEE MAIN stands at around 1.5 million as against an intake of about 10,000 by all IITs in India. Successful candidates, may appear for IIT Advanced. The number of students who appeared for IIT Advanced in the year 2012 stands at 506,000. That is one student is selected out of 50, just to get entry in an IIT, irrespective of the branch of study. Apart for IITs, there are other primier institutes like NIT (National Institutes of Technology) and BITS (Birla Institute of Technology), and others.

The very fact that none of these institutes appear in top 200, one wonders if there is any improvements that need to be done.  It may be necessary to include the following in selecting the best universities:

1. Competition that a student has to face to get selected (total number of students applied to the number of seats available)

2. Competition that a faculty member has to undergo for getting selected (number of applications received for a faculty position).

3.  The international staff ratio may be waived for universities in India because being a populous country, lot of talent exists withing the country.

4. Number of entrepreneurs created over the past 10 years or so on a rolling average basis.

On the other hand just see the stats released by PitchBook Data, a US-based private equity and venture capital research firm.  Indian Institutes of Technology (IITs) are ranked fourth on a list of 50 best entrepreneurial undergraduate institutes in the worl

Indian look forward to a more inclusive stats during the years to come.

Vijayawada – The New Capical of Andhra Pradesh!

Nara C Babu
Nara Chandra Babu Naidu

AP cabinet, headed by the Chief Minister of Andhra Pradesh, has finally resolved to announce the capital of Andhra Pradesh. It is going to be developed around Vijayawada on the banks of river Krishna.

It may be recalled that the state had been divided by creating a new state of Telangana,  and the state of Andhra Pradesh remained without capital for over 6 months. The existing capital of AP (Hyderabad) had been announced as the capital of Telangana.

Vijayawada, along with Guntur, Tenali, and Mangalagiri (called VGTM) is going to form the new capital of Andhra Pradesh. The whole region is likely to be part of greater Vijayawada.

The state is still looking at the center for implementing the promises that it had agreed to while dividing the state. Most notable among these are:

1. Financial help in the development of new state capital

2. Declaration of residual state of AP with Special Ss, which means that the companies enjoy tax holiday for a pre-determined period of time (about 5 to 10 years).

3. Special package to backward districts in AP

4. Completion of Polavaram Dam

however, no significant funds have been allocated for so far for development of state by the Modi government so far.  Also, the special status is still pending. It remains to be seen whether the AP govt will succeed in getting required resources and assistance for the central government to fulfill its promises to the people of AP.

Good luck!

Indian Prime Minister Narendra Modi Completes 100 days in Office

Narendra Modi

Indian Prime Minister Narendra Modi completed 100 days in office. Here are a few observations:

1. Set the ball rolling on un-earthing black money stashed in swiss banks by constituting a committee.

2. Visited Bhutan for improving bilateral trade and cultural relations.

3. Presented first budget,in which he contemplated smart cities, and bullet trains.

4. Visited Japan for investments in India and exchange of cultural activities. Japan promised to invest up to 35 billion USD in India during next 5 years.

5. Expedited road and rail constructions in border areas to improve movement of army personnel, and civilians in border areas.

6. Chinese premier will be visiting next week with a proposal to set up technology parks in Ahmadabad and Pune, with investment up to 7 billions.

7. The GDP of the country seen a small improvement during the first 3 months of this FY 2014-15, which may be primarily distributable to Modi sentiment.

There are great expectations from Modi government, and it is generally believed that the economic, social, and defense areas are going to be strengthened over the next few years.

Good luck!
