ISRO successfully launched PSLV-C25 Mars Orbiter Mission

About 450 crores of rupees expenditure, is it really needed? this type of critics are araised so many on ISRO. However, ISRO has only one determination to make India among one of the best countries in Space Research, in the view of that ISRO is doing its best by its experiments.

Recently, ISRO successfully launched Mars Orbiter Mission which costs less compared to sophisticated war craft. All phases of rocket are completed successfully and the Mission is travelling towards Mars and it will reach Mars in 300 days approximately. After that it reaches Mars, even though sending Mission to Mar’s Orbit is a great victory by ISRO scientists.

Shortly India is going to sign its victory on Mars, India has its valuable time today. ISRO scientists received so many appreciations from different parts of the world.

Till now there are only three nations that reached Mars, now India is on its race to get that fame and create history. Lets pray ISRO will reach that credit hopefully.

PSLV-C22 Successfully Launches IRNSS-1A, India’s First Navigation Satellite


ISRO’s Polar Satellite Launch Vehicle, PSLV-C22, successfully launched IRNSS-1A, the first satellite in the Indian Regional Navigation Satellite System (IRNSS), in the early morning hours of today (July 2, 2013) from Satish Dhawan Space Centre, Sriharikota. This is the twenty third consecutively successful mission of PSLV. The ‘XL’ configuration of PSLV was used for the mission. Previously, the same configuration of the vehicle was used thrice to launch Chandrayaan-1, GSAT-12 and RISAT-1 satellites.

At the completion of the countdown, PSLV-C22 lifted off from the First Launch Pad at 23:41 hrs IST yesterday (July 1, 2013) with the ignition of the first stage and four strap-on motors of the launch vehicle. The important flight events, namely, stage and strap-on ignitions, heat-shield separation, stage and strap-on separations and satellite injection took place exactly as planned. After a flight of 20 minutes 17 seconds, the IRNSS-1A Satellite, weighing 1425 kg, was injected to the intended elliptical orbit of 282.46 km X 20,625.37 km.

After injection, the solar panels of IRNSS-1A were deployed automatically. ISRO’s Master Control Facility (at Hassan, Karnataka) assumed the control of the satellite. In the coming days, five orbit maneuvers will be conducted from Master Control Facility to position the satellite in its Geosynchronous Circular Orbit at 55 deg East longitude.

IRNSS-1A is the first of the seven satellites constituting the space segment of the Indian Regional Navigation Satellite System. IRNSS is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland. IRNSS would provide two types of services, namely, Standard Positioning Services (SPS) – provided to all users – and Restricted Services (RS) provided only to authorised users.

A number of ground stations responsible for the generation and transmission of navigation parameters, satellite control, satellite ranging and monitoring, etc., have been established in as many as 15 locations across the country.

The entire IRNSS constellation of seven satellites is planned to be completed by 2015-16.
